Well, good day and welcome to Day 28! Well done on getting here. I really, really appreciate you and commend you if you've made it all the way through to this point. If you have, you've learned so much.

You know that amazing organ inside your chest is beating 100,000 times a day for you. It starts beating within weeks of conception in utero and will give you three billion beats in a lifetime. And if it stops, so do you.

So, how do you look after it? We've touched on diet. We've talked about exercise. We've covered the importance of sleep and stress. We've discussed the Harvard longevity study and the importance of relationships. We've talked about genetics—you can't change those. We've talked about medications, and we've even talked about risk and the kinds of testing you can do to be more precise about your risk.

What are you going to do from here on? I hope one of the things you've really taken on board is the importance of being precise about your risk and the value I've attached to individuals considering a coronary artery calcium score as a rite of passage. Men moving from 45 to 50 years of age and beyond, and women from about 55 to 60 years of age and beyond, should consider it—unless there's a risk enhancer like a premature family history of coronary disease or significantly elevated cholesterol levels.

How are you going to lock some of these changes into place? One of the key things is to make small, doable changes. Lock in with someone—maybe your partner, spouse, someone at work, or someone you care about—and support each other’s health. Do it together. Look at things you can change in your diet. Look at things you can change with exercise. Simple things.

Set goals. Use the SMART goals process—specific, measurable, achievable, relevant, and time-bound. Don't put things off. Recognize that your healthy heart journey is about being informed before a problem occurs. Get those checks. Know your cholesterol levels. Know your blood pressure. Make sure you're not pre-diabetic. Sleep well. Exercise regularly. Know your calcium score. These are all key pieces of information that can be addressed before a problem arises. Embrace them and think about how you can integrate them into your ongoing health journey.

Once you've done that, simple things on a daily basis will make an enormous difference. If you are given medications, don’t stop them unless it’s clear, with the person who prescribed them, why you would stop or what the strategy is around stopping them.

There will be lots of resources at the end of this. If you're interested, I'd love to support you with even more detail for an ongoing deep dive into heart health and broader health-related issues. My Healthy Heart Network has been evolving into the Healthy Life Network. Every fortnight, I present a live session where members can contribute, ask questions, and even suggest topics for me to cover in a live Zoom call. We've got plenty of resources attached to that, so check out the resources on this particular day and see if it could be valuable for you or someone you care about.

Again, congratulations on getting this far. I am truly grateful that you've listened and engaged to this stage, and I genuinely hope that I’ve given you information that will make a real and meaningful difference in your life.

I honestly hope you live as well as possible for as long as possible. Take care and bye for now.

Are You at Risk of a Sudden Heart Attack? How Healthy is Your Heart? Really?

Heart disease is the #1 killer in the Western World. In Australia, someone dies every 28 minutes from heart disease. That’s 51 people a day. In the US, someone has a heart attack every 40 SECONDS! Fortunately, many heart attacks are preventable. However, regular exercise and eating healthy are no guarantee you won’t succumb to this silent killer.

94% of Australians have at least One Risk Factor for heart disease.
59% of Australians have been Touched by heart disease.
Yet only 3% of Australians have had a Full Heart-Health Assessment in the past 12 months.

G'day and welcome to Day 27! We're really so close to the end of this challenge. First of all, thank you for getting this far. We are at the stage where we need to be thinking about locking in some of the things that you've learned over these last, well, almost three weeks.

It's really important to understand that small changes that can be sustained can make big dividends over a long period of time. So just think about some of those small changes that you can make in your diet—maybe adding a little bit of extra veggies or salad into your meals, leaning towards leaner protein choices, particularly trying to get more fish on board, especially fatty fish. Make an effort to seek out and reduce saturated fats, processed foods, and foods high in salt. Little changes, sustainable changes—they'll make a big difference.

Exercise is also really important. As we went through the exercise days, I made the point that you've got to enjoy it. If you don't enjoy your exercise, you won't do it. So whatever it is for you, I hope you're able to find several sessions a week—maybe five sessions of 30 minutes of moderate exercise, walking, or something that makes you happy and fits into your life. Also, try to incorporate more movement into your daily routine—taking the stairs instead of the elevator or parking a bit farther away instead of always opting for the closest spot.

We will have touched on smoking. If you've got this far, my gut feeling is you're probably not a smoker, but if you are, no one's going to judge you. Just for your own health and for those who love you, please think about quitting.

Managing stress is also crucial, as stress has a negative impact on your health. Sleep is really important too. Many of us enjoy alcohol—some go without it, but others may drink a bit too much. What starts as one or two glasses can easily become three or four. Keeping hydrated is also essential, so take a bottle of water with you throughout the day.

It's really nice to try and support local, especially if you know the provenance of your groceries. Try to reduce waste and bring simple, sustainable habits into practice. By walking just 30 minutes a day, you can reduce your risk compared to someone who isn’t active by over 30%. Eating two servings of fish a week can reduce your risk of an event by nearly the same amount. Similarly, not getting enough good-quality sleep increases your risk.

So as you reflect on what you've learned over these past three weeks, think about the little changes you can implement easily and sustainably to support your best health journey moving forward.

For now, I’m going to wish you the very best. I do hope you live as well as possible for as long as possible, and I look forward to speaking with you tomorrow. Take care and bye for now.

Welcome! Today is the 26th, and we are talking about medication. There are millions of people who take heart-related medications, and the really good thing is that we have plenty of medications in the cardiovascular realm to help with all sorts of aspects of cardiovascular care. So, let's talk about blood pressure tablets.

First of all, we've got beta blockers. They dampen down the sympathetic nervous system, slow the heart, and reduce blood pressure. We also have these wonderful agents called angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, which work through the angiotensin system to help blood vessels relax. The same agents are really good for cardiac failure—so are beta blockers, as it happens.

Calcium channel blockers come in different types. Some slow the heart while also opening the arteries, while others work more peripherally by opening the arteries with less effect on heart rate. We can also use diuretics, such as thiazide diuretics, and sometimes mineralocorticoid-blocking diuretics like spironolactone, which can help with blood pressure as well.

When it comes to cholesterol lowering, you’ve likely heard of statins, but these days, we're adding other agents as well. Ezetimibe, for example, blocks cholesterol absorption from the gut. We're also using agents called PCSK9 inhibitors because PCSK9 is a protein that, if blocked, improves the cycling of cholesterol receptors on liver cells. If the receptor is working better, it pulls more cholesterol out of the bloodstream, reducing LDL cholesterol—the "bad" cholesterol.

We've also got drugs that prevent blood clots, such as aspirin and aspirin-like medications, which are used routinely if you’ve had a stent. Additionally, we have blood thinners that work differently, known as anticoagulants. You may have heard of warfarin—it was once referred to as rat poison, and in its first iteration, it was. However, in very controlled doses, warfarin has been used to thin the blood. These anticoagulants differ from antiplatelet agents, which act on platelets—the tiny components that clump together in the blood to aid in clotting. Aspirin and aspirin-like agents target platelets, while blood thinners work on the proteins that aid in coagulation.

Newer blood thinners, available for about five years, are called non-vitamin K oral anticoagulants. We also have medications that reduce chest pain, such as nitrates—sprays used under the tongue to open up arteries and ease anginal pain. It's important not to mix this spray with certain medications, particularly Viagra.

Without going into further detail about these heart-related medications, I really want to stress two key points. First, if you are on heart-related medications, please carry an up-to-date list with you at all times. If you see a doctor and they ask what medications you are on, don’t shrug your shoulders—pull out your list and show them. Imagine how much better care you'd receive in an emergency if that was the case.

Second, and this is extremely important, if a cardiologist has prescribed you medication for a specific purpose and you believe you're having a problem with it, please go and talk to the person who prescribed it. Understand exactly why you are on it and what strategies you need to implement to assess whether it is causing an issue.

For example, if you were to stop taking a blood thinner like aspirin after receiving a stent, you would run an extremely high risk of a clot forming within the stent, suddenly blocking the artery. That could be the last thing you ever remember. So, please don't just stop your tablets—talk to someone, be clear on what the medication is doing, and understand the next steps.

Well, that's it from me. I do hope you live as well as possible for as long as possible, and I look forward to seeing you tomorrow. Take care, and bye for now.

Hi and welcome to Day 25, and this is probably one of the most important days if you ask me. What I want to get across is how heart attacks can occur out of the blue in people who otherwise seem healthy—no signs, no problems.

I am going to ask you to take a moment to check out the resources associated with this particular day because I'm going to include my TEDx talk, which is a personal experience where I dealt with a patient who had exactly that occur, and it changed the way I practice cardiology. So please check it out.

What's really, really important is to understand that we don't feel raised cholesterol. But what's also really important is some of these statistics that we know: nearly 50% of heart attacks occur in people who have normal cholesterol. So don't use that as a reassurance. For many people, the very first symptom of heart disease is a heart attack—nearly 20%. And of heart attacks, one in six, that's 15%, will be fatal.

When we look at people who have heart attacks, up to 20% to 25% of all heart attacks occur in individuals 65 years of age or less. Since heart disease affects nearly 20% to 25% of the entire population, we are all at risk until we know otherwise.

So what really catches us? Cholesterol building up in the arteries doesn't give you a symptom. And here's the key: you won't get a symptom from the buildup of cholesterol in the arteries until that cholesterol has built up so much that it limits flow down the arteries, or becomes flow-limiting.

That makes sense—if you exercise and have flow-limiting plaque in your arteries, not enough blood gets down that artery to supply the heart as it should. The heart then suffers the consequences of this lack of blood flow, which is equivalent to cramp. This gives rise to pain, stiffness, shortness of breath, and discomfort—the anginal syndrome you may have heard of.

But here’s the bit I really want you to understand. Before plaque builds up to being flow-limiting, it is non-flow-limiting. If it's non-flow-limiting, it does not restrict blood flow down the artery at all, even when someone exercises full tilt.

Why is that important? At autopsy, when doctors cut open the arteries to examine what happened, they find that nearly 40%—that's almost half—of all heart attacks occur on plaque that was not limiting flow up until the moment it ruptured, burst, and formed a clot.

This is so, so important to understand. It means you can be walking around completely symptom-free with a plaque that is not limiting blood flow but has the potential to rupture suddenly. When a clot forms on that ruptured plaque, it can block the artery suddenly, leading to a heart attack out of the blue.

So what can you do? We've talked about traditional risk checks. We've talked about checks with your GP. We've talked about managing blood pressure. But in my opinion, one of the single most important things to do is to look at the health of your arteries and consider getting a coronary artery calcium score.

I've talked about this multiple times. You can check it out at virtualheartcheck.com, where you can organize a scan for yourself. Men aged 45 to 50 and above, and women aged 55 to 60 and above, should think of it as a rite of passage to see what's going on.

Please check out the resources for today. I'm really looking forward to tomorrow and the last couple of days. Thank you so much for being attentive and getting this far. I really hope that today sinks in, resonates with you, and leads to action.

For now, I truly hope you live as well as possible for as long as possible. Take care and bye for now.

Hello and welcome to Day 23, and we are on one of my favourite soapboxes—the role of traditional risk calculators, but most importantly, their limitations.

I really, really, really want you to pay attention here. This is super duper important. By the time you get through this podcast, my short video, and the resources—which I'm really going to ask you to check out this time—I hope you realise traditional risk factor calculators are really quite a waste of time. We've used them for years, but it's only because they've been the best that we've had.

To a large degree, these risk calculators work by observation—observing populations and the rates of events in people with different characteristics, and therefore taking those characteristics as associations to an event. Now, that might mean, for example, if we put some details into a risk calculator—say a man 50 to 55, his cholesterol is borderline average, his blood pressure is borderline average, his ECG is normal, he's not diabetic—his risk might be calculated at, say, 5 or 6% over the next 10 years.

Now, a couple of problems with this. When that risk calculator says the risk is 5 or 6% over the next 10 years, what it's really saying is if you take a hundred people with the same characteristics and follow those 100 people for 10 years, then 5 or 6 of those people will have a cardiac event. 94 won't, but 5 or 6 will.

A risk calculator doesn't tell you your risk. What it does is it tells the doctor and you the rate of events within a population of people just like you. Now, I don't have any patient who comes into my practice and says, "Dr. Bishop, I'd like to know the rate of event within the population I sit," because that's meaningless. What the person wants to know is, am I going to have an event?

And the reality is that for anyone over the next 5 to 10 years, their event rate will either be 0%—nothing will happen—or 100%. You can't have an event rate for an individual of 5 or 6%. So, a risk factor calculator does not calculate the risk of the individual if you're using those traditional risk factor associations—things like age, sex, blood pressure, smoking history, diabetic history, cholesterol levels, and so on.

This is why I'm so passionate about people getting a direct evaluation of the health of their arteries. Imagine if we could take that population of 100 people where we know 5 or 6 of them will have an event. And what if we could scan all those people and look at their arteries using their coronary artery calcium score and identify those who are truly at high risk or appear to be at high risk? We can implement therapy for those, and we can genuinely reassure the others.

So, when it comes to traditional risk factor calculators, they're not a bad idea. They were the best that we had a long time ago. My own feeling is we do much better bringing precision for an individual.

I'm going to leave you with that for now, and I really look forward to catching up with you tomorrow. In the meantime, live as well as possible for as long as possible.

Take care and bye for now.

Hi and welcome to Day 24, and we're talking about testing of the heart.

Well, we've talked about traditional risk factor calculators, and I'm not sure that they're the bee's knees, so let's talk about some other stuff. I've already touched on coronary artery calcium a few times, and this is a great way to actually be precise about your risk.

In my perfect world, every male 45 to 50 years of age and every female 55 to 60 years of age should have a coronary artery calcium score done as a rite of passage as we age. One in four people are affected by coronary artery disease, so why wouldn't we check? That's pretty straightforward, and I think I've even got links to show you where you can organize your own scan without even the need to see a GP or a specialist. Check that out—that's virtualheartcheck.com—and you can pursue that as you see appropriate. Those ages I gave you? You might even do that scanning a little bit earlier if there's a really bad family history.

Well, what are the other tests we can use? If we think that there is a buildup of plaque in the arteries, or rust in the pipes if you like, and we think that buildup is so much that it might be limiting flow, we can put people through some sort of stress test or functional test. If we combine that with an ultrasound or an echocardiogram, then we can get readings on the electrical response of the heart and how the heart contracts by looking at it with ultrasonography.

A heart that's not getting enough blood shows electrical changes that we monitor, and a heart that's not getting enough blood cramps—it doesn't move properly. So stress echocardiography is a great way to assess if there's flow limitation.

You may have heard of coronary artery calcium scoring because I've been talking about it a lot, but if we take a coronary artery calcium score-style test and add dye or contrast and inject at the same time, we can outline the arteries with even more detail. This is called a CT angiogram, and it's really, really valuable. We tend to use it for individuals who have symptoms. It's not standard for risk.

You may have also heard of MRI scanning of the heart, and this is a beautiful tool used for a number of different parameters within heart evaluation, particularly things like the quality of the heart muscle itself. Are there changes that point to there being deposition of some sort of compound, chemical, or protein within the muscle? How well is the muscle working? Can we see scar within the muscle of the heart?

MRI also helps assess how well the valves are working, and we can get very, very accurate assessments of valve leakage. We can also get very accurate assessments of the function of things like even the aorta. So cardiac MRI imaging provides exquisite images for really evaluating hearts when we have some uncertainty and need more detail.

To summarize:

Coronary artery calcium scoring – Highly recommended to really figure out your risk.

Stress testing/functional testing – Used if we think there could be a risk of any flow-limiting plaque buildup in the arteries.

CT coronary angiography – A great test, more precise than coronary artery calcium scoring, and used for people with symptoms.

Cardiac MRI – A beautiful test giving us exquisite images, but it does take a while and is fairly expensive. It provides great insight into the integrity and quality of the muscle, any features of scar, and any problems with the valves.

For now, I'm going to wrap up. I look forward to seeing you at Day 25. Until tomorrow, I hope you live as well as possible for as long as possible.

Take care and bye for now.

Welcome to Day 22, and we're talking about the importance of checkups. Well, honestly, for me, this seems like common sense.

We all get our car checked. When I get an email or a text from the local Toyota dealer, I take my car in and get it checked, even if it's running well. And that's because things can go wrong even when things appear to be going smoothly—and the heart is no different.

You may have elevated cholesterol levels. You can't feel that. The only way you can know is by checking. Your blood pressure may be up a bit. You don't know that unless you go and get it measured. It's so important to be proactive about your heart health. If you believe that nothing will ever happen to you, then you probably have a misplaced belief. Everyone will have something go wrong over time, given long enough.

So what can you do? We're just going to get checked up. Get simple things done like blood pressure, cholesterol, and sugars. All these are super duper important. I talk about coronary artery calcium scoring over and over in this 28-day program, so please think about that. I've even provided a link for you to be able to obtain that without the need to see a GP or a specialist.

It's really important to recognize that there can be significant problems within the arteries, and people can feel well right up until the time that they don't. The very first presentation of problems with the arteries can be a heart attack. And of those heart attacks, one in six people die. They don't necessarily give you a second go. Heart attacks are not charitable.

So who should get checked? Well, certainly blokes 45 to 50 should be thinking about getting screened for cardiovascular disease. Women about 55 to 60. And you'd probably do that a bit earlier if there was a family history. In families where there's very high, very, very high cholesterol, we might screen the children at an early age. We also know that some of our First Nations people should probably be screened earlier as well—maybe 30, 35 years of age.

What's really important to recognize is that if we can identify problems with the heart early, we've got really good strategies that can prevent a problem in the longer term. Routine checkups give us the opportunity, the charge, to identify these issues and potentially mitigate the risk or even create an alternate universe where you remain fit and well.

Do get your blood pressure checked. Make sure your weight's okay. Check your sugars. And I've flagged coronary artery calcium scoring a number of times—check that out as well.

For now, I'm going to wish you the very best. I really look forward to catching you tomorrow. Thank you for getting this far, and we are on the home straight.

Till next time, take care and bye for now.

Well, welcome to day 21, and let's blame our parents. Look, even if you eat well, exercise, and have good cholesterol, your genetics could still alter your risk of heart attack.

When we talk about family history, we're talking about young people. We're talking about males, 55 years of age or less, who don’t have a clear reason for having a heart attack early—things like smoking, obesity, or severe hypertension. When we're talking about women, it's about those 60 years of age or younger. We’re not talking about great-uncle Bulgaria who had a stroke or a heart attack at 93, because that’s not premature.

So if you do have those sorts of risk factors in the family—premature coronary disease—be aware, because there are risk factors worth checking. And sometimes we can't check them, so you just have to look.

One of the things that we're most concerned about is a lipoprotein particle or a carrier of cholesterol called lipoprotein, lowercase a, little a. This is probably the most significant genetically inherited risk that we know of. If we find families with premature coronary artery disease or early coronary artery disease within the family, we will often check for LP(a).

Currently, it’s not covered by Medicare rebate in Australia, so you will be out of pocket, probably $50 to $80, depending on where you get that done. But it’s certainly well worthwhile.

One of the other things that we often do for people who don’t appear to have traditional risks but have a family risk—because often the traditional risk calculators don’t factor family risk very well—is we think about imaging the arteries of the heart. A really good way to do that is a coronary artery calcium score. This could be done for men as young as 40, and for women as young as 50, particularly if there is a significant family history of early problems.

Obviously, if there is a bad family history, avoid the traditional things like smoking. Do try and exercise well. Do look after your diet. What’s really important to know is that just because there are bad hearts in the family doesn’t necessarily mean that’s your destiny. Remember, if it’s your mother or your father passing on the genes, you’ve only got a 50% chance of actually picking up the gene from them.

My own practice and my preference is to look and see what’s going on. I see many people who have fairly unremarkable traditional risk factors—things like blood pressure, diabetes, exercise habits, and cholesterol levels. But I go on and get imaging of the arteries done, and that really helps. If we can then identify people who’ve got the gene and we know they’re at risk, we can put strategies in place to make a huge difference.

So remember, your family is not necessarily your destiny. Though you can pick your friends, you can't pick your family. You are best playing the cards that you've been dealt, but trying to look at those cards beforehand.

Until next time, I’m going to wish you the very best. I do hope you live as well as possible for as long as possible. Take care and bye for now.

Well, welcome to day 20, and I have to say, I've got a bit of apprehension about today. We're talking environmental factors and heart health, and I feel a little bit despondent, almost embarrassed, sad that our species have taken the world to this place, where really we're talking about the impact of man on our own health, but probably the health of other animals and plants on the planet, and the impact is so detrimental. It's just, it's actually quite depressing, and it's unfortunate that we have to think about it, because it's real, and we're starting to observe it more and more.

Things like air pollution can affect your heart, because tiny particles that are called PM2.5s, these tiny little particles of, well, pollution, can end up being inhaled into your lungs, get through the blood vessels in the lungs, and into the blood vessels of your body, causing an inflammatory response. This inflammatory response can drive blood pressure. We've even found evidence of tiny bits of fragments of microscopic plastic within plaque within arteries.

Look, I honestly think this is a little bit depressing, but we have to be aware of it, because we don't want to be putting ourselves in the way of these exposures, and we need to be avoiding them where we can, and we need to be, I think, trying to hold people accountable wherever possible, and hoping, by shining a light on it, that the very people who could make a difference do start to make a difference.

So, air is problematic, particles within the air can be problematic, but also things like, well, heavy metal within contaminated soils, or even contaminated waters can be problematic. Pesticides, cleaning our food properly before we wash it, as long as our water is not tainted by lead or some other impurity, because of storage or pipes or various other aspects of the delivery of that water to us.

We do know that sudden exposures of pollution would be problematic, and one of the really interesting things that I've come across in my reading is the impact of noise pollution, and what an impact that can have, particularly on things like blood pressure, and we almost take it for granted.

What can we do? Well, I think we need to raise awareness. I think we need to talk to the people who are at the coalface of making the decisions in industry about what can be done to really move away from what's probably been historically choices that have been based on economics to choices that are based on health, and not just health of humans, but health of the planet and other organisms.

We can use filters. That's not a bad idea. You can run your car on, recirculate with its air conditioning. As you travel through traffic, you can eat an antioxidant-rich food and be mindful of chemical exposures, buying organic. All those things make perfect sense.

So, you know, it's a bit of a shout-out to a heads-up to be aware and talk to people about this. We can make small changes in our own lives, but we really need to be, I guess, talking at dinner table conversations, talking in groups, clubs, societies, and hopefully talking to our politicians and business leaders to start making the changes, not just for us, but for our kids and for other people on the planet.

So, I don't think I like that topic today. So, I'm going to sign off now. I am going to wish you the very best. Drink clean water, breathe fresh air, eat wholesome food, and wash it well, even if it is organic.

For now, I am going to wish you the very best. I do hope you live as well as possible for as long as possible, and I look forward to speaking with you tomorrow. Take care, and bye for now. Bye for now.

Greetings and welcome to day 19.

Now, we're going to be talking about social connections and heart health. I'm not sure if this is going to surprise you or if it’s common sense, but it turns out that your relationships are really important—not just for your mental health, but for your heart health as well.

The famous Harvard Longevity Study of Adult Development has clearly indicated that people with strong and supportive relationships tend to live longer, healthier lives with lower rates of nearly all diseases, including heart disease. This sort of begs the question: how do social connections protect your heart?

One possibility is that being supported by family, friends, or even your community helps lower your stress levels, and we know stress isn’t good for you. As we reduce our stress, we lower stress hormones like cortisol and adrenaline, which impact blood pressure, arteries, and heart rhythm.

Another factor is the release of feel-good hormones that come from positive social interactions. For example, oxytocin, also known as the "love hormone," helps promote feelings of calm and counteracts chronic stress.

Good social connections can also encourage healthier habits. If we are surrounded by people who support us in exercising, eating well, or getting regular medical checkups, we are more likely to adopt those behaviors ourselves.

One of the more surprising findings is that social isolation has been linked to increased inflammation. Studies have shown that people who are socially isolated have greater markers of inflammation, which increases the risk of heart disease. Observational data has also shown that loneliness is a major risk factor for heart attacks and heart-related disorders. Poor social connections are associated with high blood pressure, coronary artery disease, stroke, and early death.

So, while taking care of ourselves physically is crucial, it’s just as important to care for our mental and spiritual well-being. That’s where social connection comes in. Interestingly, it’s not about the number of friends you have—having 2,000 Facebook friends is nowhere near as valuable as having a handful of close, meaningful connections.

Whether it’s a cup of coffee with a friend, a phone call, a chat, or simply sitting down with a loved one before dinner, all these moments contribute to the importance of social connection.

So, make it a priority. Think about the people in your life who are your rocks—the foundation of your social world. Value them, appreciate them, and enjoy a healthier life with them by your side.

I'm going to wish you the very best. I do hope you live as well as possible for as long as possible. Really looking forward to talking to you tomorrow.

Take care and bye for now.

Hi, and welcome to day 18. We're going to be talking about fasting, basically, and why are we doing it and why do we bother? Well, for some people, it's potentially a way to try and drop a bit of weight, but for others of us, and I include myself, because I'm a bit of a faster, we may do it for other reasons. And when we look at fasting, if we look at cultures, we see that certain cultures that practice fasting, Lent and Ramadan and the like, these cultures with fasting as part of their cultural practices seem to show some benefit in terms of lifespan and wellbeing.

So what could be happening?

Well, it turns out that after several hours without food, your body starts to clean up the debris within the body. We call that autophagy, eating up the cells that are not doing the right job. It happens relatively soon within a fasting process, but sometimes going a little bit longer gives the body a better chance to really engage in that autophagy, that process of getting rid of the dead cells or the cells that are due for programmed cell death.

This is useful because it can reduce those cells, which as they get older can be drivers for inflammation. So getting rid of them is not a bad thing. Certainly fasting in almost all its forms improves insulin sensitivity. So someone who's carrying a bit too much weight, who reduces, who stops eating will see an improvement in the way their body responds to carbohydrate, i.e. better insulin response. With that blood pressure may improve as well.

So that's worth thinking about. And there can also be some hormonal change.

My understanding is that testosterone levels for men can pick up a little during times of fasting. Well, there are different ways to restrict food. You can use time restricted eating. That's sort of what I do. I tend to eat between the hours of about six o'clock, five thirty, six o'clock at night through till eight, eight thirty at night.

So I eat in probably a, maybe a three or four hour window. That would be referred to as four slash 20 eating. I eat in a four hour window, have 20 hours when I don't eat. For me, I find it really beneficial for my hands. I get arthritis in my thumbs. And if I break that routine, perhaps if we go skiing with friends or we're traveling and the routine gets shifted around, I find the arthritis comes back.

You could eat alternate days. You can do a 5-2 diet. You can do basically whatever works for you, or you can even follow the cultural norms within the society or community in which you live. It is interesting to see what benefit fasting can have. My own experience has been fairly positive. It's different for different people. You need to be aware that if you're looking at fasting for an extended period of time, you still need to be able to get the right amount of protein in. That's particularly important.

For me, I find it helps me maintain my weight, but really importantly, I find that it gives me quite a lot of mental clarity in the afternoons because I'm not consuming food, which often has carbohydrate in it. And then I'm not subject to that fluctuation of sugar levels, which can leave you, well, a little bit tired and yawning in the afternoon.

So fasting, very interesting. Check it out. May or may not be for you. Look at the resources we've pulled together on this one, because it is interesting.

And for now, I'm going to wind it up. I'm going to wish you the very best. I do hope you live as well as possible for as long as possible. Take care. Bye for now. I look forward to seeing you tomorrow, or at least hearing you tomorrow. Bye.

Hi, and welcome to day 17.

Look, I think I just realized I had a bit of brain fog a couple of days ago when I said, “Welcome to the home straight where you've only got a week left.” Goodness gracious. I must have thought it was a 21-day challenge. Of course, it’s not—it’s 28 days! So hang in there. But we are over the hump, so let's carry on.

Day 17, we're talking antioxidants.

What is this all about? Antioxidants, free radicals—we hear these terms all the time. Free radicals are highly reactive molecules that are generated during oxidation when oxygen is used for energy. They are a byproduct of metabolism and simply living.

The problem is that some of these highly reactive molecules can damage your cells, and in particular, we worry about the delicate lining of your arteries. When this damage occurs due to oxygen free radicals, it’s called oxidative stress. Oxidative stress is linked to atherosclerosis, increased blood pressure, and unfortunately, an increased risk of heart attack and stroke.

By dampening some of this oxidative stress, we can improve blood pressure, enhance blood vessel function, reduce inflammation, and even reduce the oxidation of LDL—the so-called “bad” cholesterol.

So what are the common antioxidants, and where do you find them? Generally, bright-colored fruits and vegetables are the best sources. Make sure there are a few of these on your plate. Berries, leafy greens, carrots, and citrus fruits all contain antioxidants. Nuts, seeds, and whole grains provide vitamin E, which is also a strong antioxidant.

Certain herbs and spices can be helpful as well. You may have heard of turmeric, which many people use for arthritis. Cinnamon and oregano also contain beneficial compounds. Dark chocolate and green tea are rich in polyphenols, which help neutralize free radicals, acting like antioxidants.

Then there are well-known vitamins like vitamin C, a powerful antioxidant. You’ll find it in citrus fruits, but the key is that the fruit must be fully ripe. Vitamin C doesn’t appear in citrus fruits until just days before they drop from the tree. So the fruit we buy in supermarkets—often picked weeks early—probably doesn’t have much vitamin C left.

Vitamin E is found in nuts, seeds, and plant oils. Lycopene, another antioxidant, is present in tomatoes and even watermelon. Lutein comes from spinach and kale. Flavonoids are found in apples, green tea, and onions. We used to say red wine was a source, but we can’t encourage drinking red wine anymore since there’s no real health upside to alcohol.

Coenzyme Q10 is another compound you may have heard of. I’ve touched on it in some of the other podcasts. All these agents may play a role in protecting the body from free radicals and have potential benefits for heart health.

Eating a rainbow-colored diet is a great way to proactively support your health. If you’re inclined, you might also consider antioxidant supplements, but always check reliable resources before making a decision.

For now, I’m going to sign off. I wish you the very best and hope you live as well as possible for as long as possible.

Take care and bye for now.

G'day and welcome to day 16, and today we're talking gut health and, importantly, the gut microbiome. Well, wow, this is interesting. And I'm obviously a cardiologist—don't know much about the gut—but I wandered into a gut microbiome presentation a number of years ago in the States at the American College of Cardiology meeting, and it was just fascinating talking about the impact of altering the gut microbiome on cardiovascular function.

Well, my brief for these short podcasts is about three to five minutes, so I'm not going to be able to cover everything I'd like to, but I have done a more extensive podcast on salt and gut microbiome health, and I strongly recommend you have a listen to that if you're at all interested. It's absolutely fascinating. But what we don't realize is that the gut really is critical to our total body well-being. And if we really, really think about it, it's really an externalized surface of our bodies internalized, because if you swallow a string from your mouth, you could follow that string all the way through to the other end. So your gut is actually exposed to what we would quite reasonably say is the outside world. The intestine is keeping our bodies from the world. And it turns out that the microbiome are protecting us from that outside world.

And that gut microbiome is complicated. Many of the bugs have features which allow them to survive in oxygen—we call those aerobic. But many cannot survive in oxygen because, deep in the gut, oxygen doesn't get in there. And we call those anaerobic. It makes it extremely difficult to measure exactly or grow exactly what bugs are in the microbiome.

But how do we do that then? Well, there are clever tests that allow us to collect a stool sample, a poo sample, send that poo sample off for evaluation where they look at the DNA particles within that stool poo sample to try and figure out exactly what gut microbiome balance, what bugs are specifically present.

Well, why do we worry about it? For a whole lot of reasons. But one of the reasons is that if you feed the right bacteria fibre, you'll get those bacteria in your gut making short-chain fatty acids, things like butyrate, which are considered to be protective for the development of large bowel cancer. We also know that feeding the right microbiome looks after that microbiome. And that microbiome then protects the endothelial lining of the gut, stopping it from becoming stressed and leaky. And if we don't have a leaky gut, that improves our immune system.

We also know that an imbalanced gut microbiome, sometimes linked to low fibre and high processed foods, can increase the production of trimethylamine N-oxide. Well, that's a mouthful. And that mouthful is abbreviated to TMAO, T-M-A-O, which has been linked to an increased risk of cardiovascular disease. So a by-product of the wrong sort of food for our gut microbiome.

Feeding your gut things like vegetables for fibre is really, really valuable. And when you do eat, instead of thinking about what you're feeding yourself for your own well-being, see if you can start to reframe it as what you're eating in terms of the well-being of your gut microbiome. Because I can assure you, if you look after your gut microbiome, it will look after you.

If you do want to know a bit more, check out the podcast on salt and gut microbiome. It's absolutely fascinating. For now, I am going to leave you. I do hope you live as well as possible. I look forward to seeing you tomorrow. Take care and bye for now.

G'day and welcome to Day 15!

Congratulations—you must see the finish line in sight! Only seven days to go. Today, we’re talking about hydration, and when it comes to hydration, the best choice is water.

Why Water?
Let’s face it—your body is about 60-65% water, and your blood is about 90% water. So staying properly hydrated is essential. However, hydration does not come from cups of tea, coffee, sweet drinks, beer, wine, or whiskey.

Water is the good stuff, so let’s stick with it.

Choosing Good Quality Water
If you’re in an area where you’re unsure about water quality, consider using a filter. You can get:

Jug filters for easy home use

Built-in water filters for your plumbing (if you own your home)

Even rainwater is worth filtering because microorganisms can contaminate it. Think about birds or possums leaving droppings on roofs, which then wash into rainwater collection systems.

Why Hydration Matters
Staying hydrated helps maintain blood volume. Dehydration thickens the blood, making circulation harder, and generally, you just don’t feel great when you’re not well-hydrated.

One of the most important long-term effects of chronic dehydration is its impact on the kidneys. Your kidneys need a steady fluid supply to function properly. This becomes especially important as we age, because our thirst response weakens over time.

Tips to Stay Hydrated
As we get older, we may not feel thirsty as quickly as we should. That’s why it helps to:

Set reminders to drink water throughout the day.

Place a glass of water in visible spots—morning, midday, and evening—to make sure you actually drink it.

Drink before you feel thirsty—by the time you’re thirsty, dehydration may have already set in.

If you’re exercising, remember:

If you feel thirsty while exercising, you’ve already waited too long.

Take small sips of water regularly when walking, running, or cycling.

Final Thoughts
Water is essential—don’t ignore it! As you age, or if you have older loved ones, be mindful of reduced thirst responses and make hydration a deliberate habit.

For now, I’m off to grab myself a glass of water—because I’m due for one!

I hope you live as well as possible, for as long as possible. Until tomorrow, take care and bye for now.

Oh, good day and welcome to Day 14!

Well done on reaching the end of week two of your 28-day challenge! Over the past two days, I’ve talked about cholesterol and blood pressure, two of my pet topics. But today, we’re tackling one of my arch-enemies—sugar and heart disease.

Why is Sugar Such a Problem?
Let’s take a moment to travel back in time—three or four million years ago, to the African plains where our ancestors roamed. Do you think there was much sugar available back then? Probably not. Sugar in their diet was likely rare and seasonal, coming from fruits or honey.

We know that sugar is an incredibly rich energy source, so when we consume it, our body reacts the same way it did millions of years ago—thinking, "Wow! What are we going to do with this great energy source?" The answer? Store it.

How Does Sugar Affect the Body?
When we consume sugar, our blood sugar levels rise, triggering the release of insulin. Insulin’s job is not only to regulate blood sugar, but also to store excess sugar in our fat reserves.

Yes, sugar gets converted into fat. If you didn’t know that before, you do now! This process leads to the formation of triglycerides, which are stored primarily around our tummy and internal organs. And that’s where the real problems begin.

The Link Between Sugar, Insulin Resistance, and Disease
Fat storage around the tummy and organs is associated with high insulin levels, which can lead to insulin resistance. This means that when you're exposed to carbohydrates, your body produces even more insulin, making it easier to store fat.

This cycle becomes self-perpetuating—the more insulin resistant you become, the more fat you store, and so on. Over time, this process also triggers inflammation, which contributes to:

Weight gain, which increases blood pressure

Higher triglyceride levels, linked to worse health outcomes

Lower HDL (good cholesterol) levels

Increased risk of coronary artery disease, cancer, and dementia

Where Does It All Go Wrong?
Much of the problem lies in modern diets full of processed foods. These often contain hidden sugars, fueling insulin resistance, weight gain, and inflammation.

What Can You Do?
Stick to whole foods—avoid processed foods whenever possible.

Drink water—it’s the best form of hydration.

Avoid sugary drinks, including fruit juices. Fruit juice is high in fructose, which is processed by the liver and, in excess, can be toxic.

Choose healthy snacks—skip chocolates, biscuits, and cakes, especially if you are insulin sensitive.

Watch your waistline—excess fat storage is a sign of underlying metabolic issues.

Final Thoughts
Be mindful of sugar. Focus on whole, sensible foods, drink plenty of water, and take good care of yourself.

I look forward to seeing you tomorrow. Live as well as possible, for as long as possible. Take care, and bye for now.

Hi, and welcome to Day 13.

Yesterday, I mentioned that cholesterol was my favorite topic and that I could talk about it for hours. Well, today we’re talking about blood pressure, and I have to confess—it’s probably equally my favorite.

I don’t want to sound boring or dull, but while many of my colleagues get excited about inserting new heart valves, placing stents, or implanting devices to help failing hearts, I get really excited when we can do the simple things really well. And one of the simplest yet most powerful things we can control is blood pressure.

Why is Blood Pressure So Important?
Let me paint a picture for you. Imagine my blood pressure is 100/120, which is absolutely fine. Over time, it creeps up to 130-135 systolic. Should I be worried? Should my doctor say, “Your blood pressure is a little high, let’s just keep an eye on it”?

Well, consider this: Going from 100 to 130-135 is about a 10% increase. And your heart beats 100,000 times a day. Do you really want your heart—the most important pump in your body—to work 10% harder than necessary? I certainly wouldn’t.

The Consequences of High Blood Pressure
Raised blood pressure has serious effects on your body:

It damages arteries, increasing the risk of stroke and heart attack.

It puts stress on the heart, which can lead to atrial fibrillation (AFib) and heart failure.

It harms the kidneys, damaging the delicate glomerular filtering system, which can lead to renal failure.

It’s linked to dementia, and studies suggest that lowering blood pressure can help reduce dementia risk.

So, in short, high blood pressure increases your risk of stroke, heart attack, heart failure, kidney failure, and dementia. That’s why controlling it is so critical.

What Should You Do?
If you haven’t had your blood pressure checked recently, go and get it done. If it’s even slightly high, don’t let your doctor say, “Let’s just keep an eye on it and check again in a few months.” It’s not their heart, it’s yours.

One tool I frequently use is a 24-hour blood pressure monitor. This is a cuff you wear for an entire day, taking multiple readings to give a detailed picture of your blood pressure patterns. It can help detect white coat syndrome (when blood pressure spikes at the doctor’s office) and identify high nighttime blood pressure, which is particularly concerning.

Final Thoughts
Be sure to check out today’s resources—there’s a lot of great information to dive deeper into this topic. But above all, get your blood pressure checked and make sure it’s properly controlled.

At 100,000 beats per day, your heart deserves to work as efficiently as possible. Take care of it.

I look forward to seeing you tomorrow. Live as well as possible for as long as possible. Take care and bye for now.

Hi, and welcome to Day 12.

My brief is to keep this podcast between three to five minutes, but today we're talking about cholesterol and heart disease—and honestly, I could talk about this for hours! I don’t even know where to start, and I definitely don’t know where to end. But one key concept I really want to convey is the misconception about “good” and “bad” cholesterol—because this causes a lot of confusion.

Right now, I’m in the process of writing a book called "Cholesterol Explained" with a colleague of mine, an Australian expert who is world-renowned in this field. Our goal is to give people all the information they need to make the best decisions regarding cholesterol and to work with their doctor more effectively.

One of the main things we want to make clear in the book is that cholesterol itself is neither good nor bad—it just is. Cholesterol is a molecule. It’s present in the cell membranes of every cell in the body. It plays a crucial role in bile salt production, is essential for vitamin D synthesis, and is a key component of hormone production. So cholesterol itself isn’t the problem.

When we talk about “good” and “bad” cholesterol, what we’re actually referring to is the way cholesterol is transported in the blood. Cholesterol is a type of fat, and since fat doesn’t mix well with water, it can’t just float around in the bloodstream on its own. Instead, it needs to be carried in particles called lipoproteins.

The two main types of lipoproteins are:

Low-Density Lipoprotein (LDL) – Often called “bad” cholesterol.

High-Density Lipoprotein (HDL) – Often called “good” cholesterol.

But here’s the thing—cholesterol is the same in both LDL and HDL. The difference lies in the particles carrying it.

To put it simply, LDL particles deposit cholesterol in the arteries, which can lead to plaque buildup and heart disease. In contrast, HDL particles help remove cholesterol from the arteries and transport it back to the liver, where it can be broken down and eliminated.

Think of it this way: cholesterol is like a young man. A young man in a bikie gang may behave very differently from a young man in a church group. The young man is still the same person, but his behavior is influenced by the company he keeps. Similarly, cholesterol’s impact on your health depends on which lipoprotein is carrying it.

So instead of asking, "Is cholesterol good or bad?", we should be asking, "Do we have too many LDL particles and not enough HDL particles?" That’s what blood tests measure, and that’s what really matters for heart health.

Please check out the resources for today—we go into this topic in even more detail.

Wow, I love cholesterol, and I hope you do too! For now, I’m going to wish you the very best. Have a great day, live as well as possible for as long as possible, and I’ll see you next time.

Take care and bye for now!

Hi, how are you going? It's day 11, and today we're talking about hot and cold therapy—saunas and ice baths. You might think these are just another wellness fad, but interestingly, these practices have been around since ancient times. Many traditions have stood the test of time because people have observed benefits. If something appears to work, people keep doing it! The good news is that you don’t have to be a top-level athlete to enjoy the benefits of hot or cold therapy—anyone can take advantage of them.

So, what does a sauna do? Well, it helps to "sweat out toxins," so to speak, but it also aids relaxation and stress relief. More importantly, saunas activate heat shock proteins—special proteins within muscle cells that alter metabolic pathways, making the cells more efficient under stress. If you think about it, the human body is an adaptive organism that responds to environmental stressors. When faced with heat, it adapts to become stronger.

Cold therapy works similarly. Cold exposure reduces inflammation and constricts blood vessels, but just as heat activates heat shock proteins, cold triggers cold shock proteins. Some people find that alternating between hot and cold exposure enhances their well-being. The idea is that exposing the body to controlled extremes toughens the physiology, potentially improving metabolism and even the immune response.

What can you do? If you're listening to this, there's a good chance you're aware of Younger Longer and the resources available there on hot and cold therapies—so be sure to check them out! But if you don’t have access to a sauna, you can try a hot bath for 10–15 minutes, as hot as you can tolerate, followed by a cold shower for a minute or two. This simple routine can give you a taste of the benefits of contrast therapy.

Hot and cold therapy is a great way to reap some of the benefits of exercise in a different form. It can be a solo practice or a social experience. In Finland, where much of the research on saunas has been conducted, regular sauna use has been linked to better cardiovascular health. Interestingly, saunas are often enjoyed in a social setting, adding a connection component to the practice.

I'm going to leave it there. Whether you’re running hot or cold on your shower tomorrow, I hope you’ve had a great day today. I wish you the very best—live as well as possible for as long as possible. I look forward to catching you tomorrow.

Take care, and bye for now!

Day 10: The Role of Aspirin in Heart Health

Hi, and welcome to day 10! Today, we're talking about aspirin, and I love discussing this topic. Aspirin is such a wonderful drug.

It was first patented by the German drug company Bayer in the 1800s, believe it or not. Since then, billions of these tablets have been produced and consumed worldwide, making it one of the most ubiquitous pharmaceutical agents. Aspirin does a heap of things—it keeps the blood thin by preventing platelets (which are involved in clot formation) from clumping together. It’s also effective for pain and inflammation because it affects prostaglandins, which play a role in temperature regulation, pain sensation, and blood clotting.

In heart health, we primarily use aspirin for people with plaque buildup in their arteries. It’s almost a non-negotiable for individuals who have already had an event such as a stroke, heart attack, stent placement, or bypass surgery. These people are at high risk, and aspirin helps prevent a second event—a strategy known as secondary prevention.

For those allergic to aspirin, alternative agents are available. However, if you have unhealthy arteries or have experienced a cardiovascular event, aspirin is one of the most affordable and effective medications to reduce your risk of further complications.

One of the more confusing aspects of aspirin use is whether people should take it before they have any heart problems. At first glance, this seems like a good idea—why not take aspirin to prevent an issue before it arises? However, taking aspirin without a clear medical reason can pose risks. Since aspirin thins the blood, it increases the risk of bleeding. For people with healthy arteries, the potential harm of aspirin often outweighs the benefit, which is why we generally do not recommend it for primary prevention.

In my own practice, I focus on identifying high-risk individuals who may look healthy on the outside. I often use a calcium score scan to assess whether plaque is present in their arteries. If I find someone with high-risk plaque—essentially, a lot of “rust in the pipes”—then I believe they might benefit from taking aspirin preemptively.

Interestingly, we don’t yet have randomized controlled trials to support this approach. However, if we follow the logic, it makes sense. If someone is going to have a heart attack at midnight, and we know that giving them aspirin at 12:00 sharp would help, then giving it to them at 11:59 should also be beneficial. By extension, if we identify high-risk patients and start aspirin treatment days, weeks, or months earlier, the benefits could be significant.

There’s a lot more to explore on this topic, so be sure to check out today’s resources. Additionally, some research suggests that aspirin may reduce the risk of colorectal cancer recurrence, which is another fascinating area of study.

That’s it for today. I wish you the very best—keep going with your challenge, and I hope you live as well as possible for as long as possible. Take care, and bye for now.

Hi, and welcome to day nine. We're talking about supplements and heart health.

Many people take some form of supplement, but the research behind them is often patchy. It can be difficult to determine whether you should take them, what dose is appropriate, and which product or brand to trust. Unlike pharmaceutical drugs, which are highly regulated and tested, supplements fall into a more uncertain category.

That said, many people like to take supplements, and some do benefit from them. My general approach is to recommend supplements if there is a theoretical or practical reason that they may help a patient. I usually suggest trying them for a couple of months—if they help, great! If not, there's no harm in stopping.

When it comes to heart health, the main supplements I encounter are magnesium, coenzyme Q10, and omega-3 fatty acids. These are probably the most popular choices.

Magnesium is something I often recommend for people experiencing heart palpitations or extra beats, as it helps stabilize heart rhythms. It can also benefit individuals with high blood pressure by promoting blood vessel relaxation. Additionally, magnesium levels in our soils have likely declined due to continuous farming, so supplementation might be beneficial. A typical dose is around 400 mg per day. After exercising, I sometimes add a scoop of magnesium to my post-workout shake. However, I avoid magnesium supplements that contain pyridoxine (a B-group vitamin), as excessive pyridoxine can cause nerve-related issues.

Coenzyme Q10 plays a crucial role in energy production within the mitochondria and acts as an antioxidant. Some research suggests it may help individuals with poorly functioning hearts and could potentially reduce muscle aches associated with statin use. While the evidence isn’t definitive, it remains a supplement worth considering.

Omega-3 fish oils are particularly valuable, especially for those who don’t eat enough fish. The omega-3 index is a useful indicator of overall heart health, and these fatty acids are incorporated into cell membranes, producing several benefits. Omega-3s can help lower blood pressure, improve heart rhythm, and even enhance cholesterol levels. Some of my patients have also reported reduced inflammation, experiencing relief from sore hands, knees, and hips. To achieve these benefits, moderate doses are needed—around four grams per day of standard over-the-counter omega-3 oils.

So there you go—a quick guide to supplements for heart health. If you'd like to learn more, be sure to check out our additional resources, which are packed with valuable information.

Until tomorrow, have a great day (or night), and I hope you live as well as possible for as long as possible. Take care and bye for now.

G'day and welcome to day eight. We're talking about sleep.

I bet you already know that sleep is really, really important. It almost underpins diet and exercise, and it wouldn’t be unreasonable to say that if you had to choose between good diet, good exercise, and good sleep, you would probably pick good sleep as the most important factor. You’ve likely experienced this firsthand.

It’s fascinating what happens while you sleep—or, more importantly, what happens when you don’t get enough sleep. Lack of sleep can impact the hormones in your body, including leptin and ghrelin. Leptin is responsible for signaling that you’re full, while ghrelin tells your body you’re hungry. When you don’t sleep well, leptin levels drop, making you feel less full, while ghrelin levels increase, making you feel hungrier. Ever had a late night and woken up the next day with the munchies? That’s sleep deprivation at work.

Sleep also has a profound impact on mental health. If you’ve ever been stressed or anxious, you may have noticed that poor sleep only makes it worse. It’s a vicious cycle—stress disrupts sleep, and lack of sleep increases stress. Breaking this cycle is crucial for overall well-being.

There are also some incredible processes that take place during sleep. The brain is surrounded by cerebrospinal fluid, which helps clear out waste products, including proteins that are linked to conditions like Alzheimer’s disease. These waste-clearing mechanisms only function properly while we sleep, making rest essential for long-term brain health.

One key thing to remember is that lost sleep early in the week can’t be fully recovered by sleeping in on the weekend. Once that sleep opportunity is gone, it’s gone.

So, how can you improve your sleep quality? Sticking to a regular sleep schedule and aligning with natural daylight hours can help. Using dim or red lighting before bed can signal to your body that it's time to wind down. Avoiding heavy meals and alcohol before sleep is also important. While alcohol may help you fall asleep faster, it actually reduces sleep quality.

There’s heaps of information about sleep, so be sure to check out some of our extra resources. Most importantly, make sure you get a good night’s sleep tonight!

For now, I wish you the very best, and I look forward to seeing you on day nine. Take care, and bye for now.

Hi, and welcome to day seven! Well done on completing the first week of the 28-day challenge. Today, we're talking about smoking and heart disease. You already know that smoking is linked to heart disease and cancer, and you don’t really need to be told that. My guess is that if you’ve gotten this far on this platform, looking after your own heart health, you’re probably not a smoker.

But if you are, I really appreciate you taking the time to listen because that means you’re open to possible change. When I speak with my own patients about smoking, I generally start off by saying, “Look, you are an adult. Whatever you do in your own life is your decision, and I have to respect that.” I’ve learned that I can barely influence my own children’s will, let alone the will of another adult who has made up their own mind.

What I then put to my patients who are smokers is this: Are they behaving with integrity in regard to who they are and the decisions they’ve made? What do I mean by that? Well, I often ask my patients who smoke, “If you had cancer, a heart attack, or a stroke—something directly related to smoking—would you continue to smoke in spite of that diagnosis? If you were told you were about to have a stroke or a heart attack, would you still smoke?”

Are you the sort of person who is a committed lifelong smoker no matter what? Do you believe that smoking is an integral part of who you are? Because if you do, then smoking makes sense—you recognize it, respect it, and understand that it’s part of your being, and I can live with that.

The flip side, though, is this: If you were to stop smoking when faced with the threat of a major diagnosis, then perhaps you’re not actually a committed lifelong smoker. Perhaps you’re more committed to your health and well-being. Perhaps you’re more committed to trying to live as long and as well as possible. And if that’s the case, then is smoking truly respecting the person you are?

I ask people to bring integrity and honesty to their own behavior. Are they behaving as someone who is a committed lifelong smoker? If so, I can respect that. Or are they behaving like someone who is not actually a committed lifelong smoker, but simply making poor choices? Those choices can be shifted. Often, it’s pain or pleasure that forces us to make changes in any particular endeavor.

I once had a wonderful patient who we had concluded was a lifelong committed smoker. I didn’t pick on him, challenge him, or ask about his smoking—I just took for granted that he was a rusted-on smoker. Then one day, he turned up and said, “Doc, I quit the cigarettes.” Naturally, I asked, “I hope you don’t mind me asking, but how were you able to change?” He said, “Doc, my grandson sat on my lap and said, ‘Grandpa, you stink.’” And there and then, he threw the cigarettes away.

That moment really underlined for me how important it is to put our choices into context. What’s the benefit for us? Where does that benefit lie?

If you’re a non-smoker and you’ve never smoked but have listened to this, I hope you’ve learned something. Share it with someone who smokes—someone you care about, or even someone you don’t know particularly well. You might make a difference in their life.

If you are a smoker and you’ve listened to this, I really hope I’ve opened the door for you to think about your smoking differently. Whatever the case, thank you for getting this far, and I look forward to the next couple of weeks.

For now, I hope you live as well as possible for as long as possible. Take care, and bye for now.

Hi, and welcome to day six, where we're talking about alcohol and the heart.

A number of years ago, probably a decade or two, we used to think that a glass of red wine was good for the heart because of antioxidants. For years, we’ve also seen advertisements for Guinness Stout portraying it as beneficial for health. However, research now suggests that there is no real health benefit when it comes to alcohol. In fact, national health councils worldwide are increasingly recommending lower alcohol consumption, particularly in relation to heart health.

Why is this the case? Alcohol can raise blood pressure, which contributes to wear and tear within the arteries. Excessive alcohol intake can also increase triglyceride levels, which is harmful. More importantly, alcohol is closely linked to atrial fibrillation, a condition characterized by an irregular heartbeat. Too much alcohol can also directly damage the heart muscle. Additionally, alcohol consists of empty calories, increasing the risk of weight gain, which in itself negatively affects heart health.

It's also worth noting that men and women are affected by alcohol differently. Women absorb and metabolize alcohol differently than men due to variations in body water and fat content. As a result, women are more likely to develop alcohol-related complications at lower doses, such as hangovers, blackouts, and even liver disease. If you're female, it’s wise to drink less than a male counterpart of the same weight, simply because of these metabolic differences.

The good news is that there are now more low-alcohol beverages available. This means you can still go out and enjoy a cider or a glass of wine, knowing that it’s a zero- or low-alcohol option. Meanwhile, your friends, who may not be as focused on their health, might choose the full-alcohol version.

For now, I wish you the very best, and I look forward to catching up with you tomorrow. Take care, and bye for now.

Hi, and welcome to day five, where we're talking about the benefits of mindfulness and meditation.

A couple of years ago, I had the privilege of looking after a patient—we’ll call him John for ease of reference. On this occasion, I was following up on his blood pressure. I had him wear a 24-hour blood pressure monitor, a small device attached to a cuff that automatically took readings. The device measured his blood pressure every 30 minutes from 7 AM to 10 PM and then hourly overnight, giving us a detailed profile of his blood pressure throughout the day.

When I reviewed John's results, something striking stood out. At around 7:30 AM, his blood pressure spiked, and then later in the day, around 5:30 or 6 PM, it noticeably dropped. Importantly, his blood pressure was perfect while he was asleep. So, I showed him the graph and asked, “John, what happens at 7:30 AM and 5:30 PM?”

His response was immediate: “I arrive at work at 7:30, and I leave at 5:30.” It was clear—his blood pressure rose as he started work and dropped as he left.

I then asked him, “Are you aware of any tension in your body while you’re at work? Do you feel like your blood pressure is up?” He admitted that he did, particularly when interacting with his staff—he owned the business, and giving instructions often made him feel tense.

I encouraged him to practice mindfulness during his work interactions. Holding onto tension and stress wasn’t improving outcomes at work, and he already knew that. However, it was harming his health. I asked him to become more aware of how his body felt while speaking to his employees—was he holding tension in his chest, his shoulders, or anywhere else? Was he feeling that same rise in blood pressure?

We repeated the 24-hour blood pressure monitor about three to six months later. The results were remarkable. By practicing focused mindfulness, John was able to significantly change his blood pressure responses. Not only was his nighttime blood pressure good, but now his daytime readings had also improved, even while he was at work.

This shows just how important mindfulness is. Prolonged stress doesn’t just disappear—it accumulates over time and can have serious health consequences. Take a moment to consider: Are you holding onto more tension than necessary? Are there certain situations that are winding you up more than they should?

Check out the resources attached to today’s session. They are incredibly valuable and can help you on your journey to better heart health.

Until tomorrow, take care. Wishing you the very best—bye for now.

Day 4: Stress, Anxiety, and Heart Health

Mon, 17 Mar 2025 17:41:51 +1100

Chronic stress can significantly impact heart health by increasing the risk of heart disease through mechanisms like elevated blood pressure, increased inflammation, irregular heart rhythms, and promoting unhealthy coping mechanisms like poor diet and lack of exercise, ultimately leading to a higher likelihood of heart attacks and strokes; even short-term stress can trigger adverse effects on the heart, especially in individuals with pre-existing heart conditions.

Hi, and here we are at day four, talking about stress and anxiety. We all experience stress at some stage—it's a normal part of life. In small doses, short bursts of stress may not be so bad. A little bit of anxiety before an exam, for example, can help sharpen focus and put you in the right frame of mind. However, too much stress and anxiety can cause problems. If stress becomes prolonged, those "butterflies" in your stomach go from flying in formation to complete chaos, leading to serious health consequences.

When you're stressed, your body releases hormones like adrenaline and cortisol. These are fight-or-flight hormones, designed to prepare you for short-term, high-intensity situations. However, they are not meant to be active long-term. Chronic stress exposure can lead to high blood pressure, which increases the risk of atherosclerosis—the buildup of plaque in the arteries that can lead to coronary artery disease. Long-term stress also triggers inflammation, disrupts sleep, and can even cause irregular heartbeats.

To make matters worse, many people develop unhealthy coping mechanisms in response to stress. Some turn to smoking, drinking alcohol, or overeating, while others stop exercising altogether—even though exercise is one of the best ways to combat stress.

So, what can you do?
Recognizing when you’re stressed is the first step. Self-awareness is key. To manage stress, consider incorporating breathing exercises, meditation, yoga, or mindfulness into your routine. Regular exercise can be as effective as anti-anxiety medications and mild antidepressants. A healthy diet and good sleep hygiene are also critical for stress management.

If stress becomes overwhelming despite these efforts, seek help. Stress is a part of life, but learning how to manage it effectively gives you more control over your well-being.

Please check out the resources attached to today’s session—some of them may be incredibly valuable for you. For now, I’m going to sign off, and I look forward to seeing you on day five.

I wish you the very best—live well for as long as possible. Take care, and bye for now!

Day 3: The Role of Exercise in Heart Health

Mon, 17 Mar 2025 17:33:48 +1100

Regular exercise reduces blood pressure, improves circulation, and strengthens the heart muscle. In fact, exercise impacts a myriad of body systems including skeletal-muscular system, endocrine and neurological systems and resultant issues such as Diabetes and mental health, in addition to the benefits associated with cardiovascular function.

Hi, and welcome to day three! Today, we're talking exercise. You would have to have almost lived under a rock not to know that exercise provides significant benefits—not just for your heart but for your overall well-being.

When it comes to exercise, there are different types of activities we can do. Aerobic exercise, such as walking, swimming, or running, gets the heart rate up, improves circulation, and enhances oxygen delivery. This is a little different from strength training, which focuses on building muscle. So, which is more important? The truth is, you probably need both. What we do know is that regular exercise is incredibly beneficial. It can lower bad cholesterol, raise good cholesterol, and reduce triglycerides (the free fats in the body). It can also lower blood pressure, improve mental health, and help with weight control.

So, how much should you do? There’s really no upper limit unless taken to extremes, but any exercise is better than none. The general recommendation from major health organizations is 150 minutes of moderate exercise per week. If you prefer to do it in less time, 75 minutes of vigorous exercise is another option. That breaks down to about 30 minutes, five to six days a week, allowing for a rest day or two. If you're doing vigorous activity, 10 to 15 minutes, four to five times a week can be enough. You can break it up however you like—exercise is gold, and even small amounts make a difference.

Exercise changes insulin resistance, boosts metabolism, and provides benefits far beyond the time invested in it. Try to incorporate movement into your daily routine—take the stairs, and maybe even rush up them occasionally to get your heart rate up. The key is to find an activity you enjoy, because if you don’t enjoy it, you won’t stick with it. However, if you do, there’s every chance it will become a lifelong habit.

Check out the fantastic resources attached to today’s challenge for more ideas and inspiration. I look forward to seeing you tomorrow!

All the best, take care, and bye for now.

Hi, and welcome to day two! Today, we're talking about nutrition. You're probably aware that diet is a huge component of heart health because it has significant impacts. Good nutrition and sensible eating can alter your cholesterol—not by a lot, but a little. While eating cholesterol itself doesn’t have a huge impact on your measured blood cholesterol, consuming saturated fats will tend to push those levels up.

Certain foods can also increase your blood pressure and contribute to inflammation. One of the most interesting things we're beginning to observe is that when thinking about your diet, it's not just about how it affects your body directly, but also how it impacts your microbiome. Damage to the microbiome can harm the cells that line the gut, which in turn affects the junctions between those cells. This can lead to leaky gut and other related consequences.

So, what is key to a heart-healthy diet? Protecting your microbiome is crucial, and you can do this by including good grains and fiber in your diet. Healthy oils like olive oil, avocado, nuts, and seeds are also beneficial. Lean proteins help reduce saturated fat intake, which is another important factor for heart health.

What are some practical tips for everyday meals? Try swapping out white processed bread for something with more fiber. If possible, choose brown rice over white rice. Opt for unsalted nuts instead of chips, and use olive oil instead of butter. Cutting back on sugary drinks is also a great step. Vegetables are essential, not just for their nutrients but also for their fiber content. Remember, small changes made consistently over time can have a significant impact on your heart health.

Check out the resources attached to this day for more hints, tips, and guides. But most importantly, make a decision to prioritize your diet. We can’t be perfect all the time, but let’s try to be as kind to our hearts as often as possible.

Take care, and I look forward to seeing you tomorrow!

Day 1: Understanding Your Heart Health

Mon, 17 Mar 2025 17:03:39 +1100

The heart beats approximately 100,000 times a day, pumping blood throughout your body. Understanding how it works is the first step in taking control of your heart health. The primary function of the heart is to pump blood throughout the body, delivering oxygen and nutrients to tissues while simultaneously carrying waste products like carbon dioxide back to the lungs for removal; this process is achieved through the heart's four chambers and valves which regulate blood flow, all powered by the heart's intrinsic electrical system that maintains a steady rhythm of contractions and relaxations.

Hi, and welcome to day one! I'm really keen to talk about this amazing organ that lives in our chest and that most of us take for granted. You probably didn't know, but your heart starts to pulsate and beat at just 22 days post-gestation. At that stage, we're not even the shape of a living organism yet. It's quite remarkable! Over an entire lifetime, we get nearly two and a half to three billion beats from our heart. It pumps about 7,500 liters of blood every day—that's enough to fill 20 backyard swimming pools every year.

The structure of the heart consists of four chambers: two top chambers and two bottom chambers. The top chambers are called the atria, while the bottom chambers are called the ventricles. Each atrium and ventricle together form either the left or right side of the heart. The left side of the heart pumps blood out to the body, which we feel as the pulse at our wrist. Meanwhile, the right side of the heart pumps blood into the lungs. Valves positioned throughout the heart act as one-way gates, ensuring that blood moves in the correct direction as the heart squeezes.

One of the most fascinating aspects of the heart is that it pumps the blood that also supplies itself. The arteries carrying blood away from the heart eventually return oxygenated blood to nourish the heart muscle. This incredible pump accelerates, decelerates, and responds to our needs in seconds.

Another amazing feature of the heart is that it is made up of cells with a unique characteristic called automaticity. This means that if you were to take a single heart cell out of the body, it would continue to pulsate rhythmically on its own. It’s almost eerie to think about, but truly remarkable! When all the cells of the heart function together, they act as a single unit. The term for this is **syncytium**.

If you're looking for more information, please check out the printed resources attached to this day. Otherwise, I look forward to catching you tomorrow. Take care, and bye for now!
