Heart Health as You Age: The Essential Habits Made Simple

Your heart and blood vessels change with age. Artery walls stiffen, maximum heart rate falls and blood pressure tends to rise. The research is consistent that a large share of how this plays out is linked to everyday habits: movement, sitting time, food, sleep, stress, tobacco and knowing your numbers. Many of those habits are still worth starting in your sixties, seventies and beyond.

This guide explains what normally changes, what large studies and major guidelines say about each habit, how to read your own heart health numbers, and a simple weekly checklist you can take to your next appointment.

• Normal ageing: stiffer arteries, a lower maximum heart rate and a slower heart rate recovery after effort are all expected. A lower peak is not the same as disease.
• Fitness is modifiable: cardiorespiratory fitness tracks closely with healthy ageing in population studies, and older adults still adapt to training.
• The big guideline habits: regular movement, less long unbroken sitting, a whole-food eating pattern with less salt, 7 to 9 hours of sleep and no tobacco.
• Know your numbers: blood pressure, cholesterol and blood glucose often give no symptoms, so checks matter.
• Talk to your doctor or pharmacist before a big change in exercise, diet or supplements, especially if you have a heart condition or take regular medicines.

At a glance

• Stiffer arteries, rising blood pressure and a lower maximum heart rate are normal with age, but habits shape how much they matter.
• The WHO recommends 150 to 300 minutes of moderate activity a week, plus strength work on two or more days.
• Break up long sitting, eat a whole-food pattern and keep salt below 5 grams a day.
• Aim for 7 to 9 hours of sleep and avoid tobacco.
• The biggest mistake is waiting for symptoms, because blood pressure, cholesterol and glucose are often silent, so get them checked.
• Talk to your doctor or pharmacist before big changes, and call emergency services for chest pain or sudden weakness on one side.

What normally changes in the heart and blood vessels with age

The heart does not simply wear out in a straight line. Ageing brings a collection of changes that together shift how the system works.

Stiffer arteries and rising blood pressure

The large arteries gradually lose some of their springiness. When they stiffen, the pressure wave from each heartbeat travels faster and the top number in a blood pressure reading (systolic pressure) tends to drift upwards with age. This is one reason blood pressure checks become more important as the years go on, even in people who feel perfectly well.

A stiffer heart muscle

The heart muscle tends to relax a little less readily between beats, so filling relies more on the final squeeze from the upper chambers. Day to day you will not notice this, but it helps explain why hard efforts feel different at 70 than at 40.

Lower maximum heart rate

Resting heart rate often stays much the same, while the maximum heart rate you can reach during hard effort typically falls with age. That is expected, and it is why age-adjusted training zones exist. It is not a sign that the heart is failing.

Changes that are not just about time

Researchers separate changes caused by time alone from changes linked to inactivity, weight gain, smoking, poor sleep and high blood pressure. Studies of lifelong exercisers show that some age-related stiffening is smaller in people who stay active, which is the encouraging part: much of what people assume is inevitable is partly habit-linked.

Why heart health deserves attention after 50

According to the World Health Organization, cardiovascular disease is the leading cause of death worldwide. Risk rises with age, and many of the main risk factors, including high blood pressure, high cholesterol and raised blood glucose, give no warning signs. That combination is why guidelines put so much weight on habits and on regular checks rather than waiting for symptoms.

The American Heart Association groups the evidence into a checklist it calls Life’s Essential 8: eat better, be more active, avoid tobacco, get healthy sleep, manage weight, and keep cholesterol, blood glucose and blood pressure in a healthy range. Sleep was added in 2022, a sign of how the research has moved. The sections below follow that structure.

Fitness and movement: the habit with the strongest signal

Cardiorespiratory fitness, meaning how well your body takes up and uses oxygen during effort, is one of the measures most closely linked to healthy ageing in large population studies. The link holds even after researchers account for familiar risk factors such as blood pressure and cholesterol.

The more useful finding is that it is not too late to improve. Training studies in people in their sixties and seventies find that fitness still responds to regular activity. You do not need to run marathons: moderate activity, the kind where you can talk but not sing, counts.

What the guidelines recommend

The World Health Organization’s 2020 guidelines on physical activity recommend that adults, including older adults, aim for:

• 150 to 300 minutes a week of moderate aerobic activity, or 75 to 150 minutes of vigorous activity, or a mix of both.
• Muscle-strengthening activity on two or more days a week.
• For older adults, varied activity that includes balance and strength on three or more days a week, to support function and reduce the chance of falls.
• Less sedentary time, replacing some sitting with activity of any intensity.

The guidelines also say that some activity is better than none. If 150 minutes sounds like a lot, start with what you can do and build up. For balance work specifically, see what the guidelines say about balance habits, and for the strength side, how strength training supports bone and muscle.

The hours you are not exercising

Structured exercise gets the attention, but research on sedentary time finds that long, unbroken periods of sitting are associated with poorer cardiovascular and metabolic markers, and this shows up even in people who exercise. Breaking up sitting with short bouts of movement is associated with better markers than sitting straight through. Standing for calls, walking after meals and taking the stairs all add up. The detail is in our guide to everyday movement and sitting time.

Eating patterns and the heart

Current guidelines have moved away from single nutrients towards overall eating patterns. Diets built on vegetables, fruit, whole grains, legumes, nuts, fish and unsaturated oils, with less highly processed food, show consistent associations with better cardiovascular health in long-term studies. Quite different cuisines, from Mediterranean-style to traditional Asian patterns, share these features.

Salt and blood pressure

Sodium is the clearest example of a single nutrient that still matters. The World Health Organization recommends adults keep salt intake below 5 grams a day, which is just under a level teaspoon, and points out that most people eat well over that. Controlled feeding trials such as the DASH-Sodium study found that average blood pressure readings were lower when participants ate less sodium. Individual responses vary, so your own readings are the best guide. Most salt in modern diets comes from packaged and restaurant food rather than the salt shaker.

Fibre, fats and supplements

Fibre-rich foods such as oats, legumes and whole grains are part of most heart-health guidance; our guide to dietary fibre sources and labels covers where to find it. Guidelines generally favour unsaturated fats (olive oil, nuts, fish) over saturated and trans fats. Supplements are a different question: a large Cochrane review of omega-3 trials found little or no effect on overall deaths or cardiovascular events, so food patterns, not capsules, are where the evidence sits. If you are weighing a fish oil product anyway, our omega-3 label guide explains what to look for, and the supplements evidence and label guide covers how to judge any product. Talk to your doctor or pharmacist before starting one, because some interact with blood-thinning and blood pressure medicines.

Sleep, stress and the heart

During normal sleep, blood pressure dips and heart rate slows. Short or broken sleep over long periods is associated with higher blood pressure and poorer cardiovascular markers in population studies, which is why the American Heart Association now lists 7 to 9 hours of sleep for adults as part of its heart health checklist. Loud snoring with pauses in breathing is worth mentioning to your doctor, as sleep apnoea is common in older adults and is linked to blood pressure. Our guide to sleep and healthy ageing covers practical changes.

Long-term stress affects stress hormones, blood pressure and behaviours such as sleep, eating and activity. Practices such as time outdoors, social connection, regular movement and relaxation techniques have been studied for their effects on blood pressure and heart rate variability as well as on mood. If worry or anxiety is a regular feature of your days, our guide to understanding everyday anxiety is a starting point, and your GP can help.

Know your numbers: what each check tells you

Several of the most important heart health factors are silent. The table below summarises the common checks. Target ranges differ between countries and between individuals, so your doctor will tell you what applies to you.

Check	What it measures	Why it matters with age	Practical note
Blood pressure	Pressure in the arteries during and between beats	Tends to rise as arteries stiffen; usually no symptoms	Home monitors can help; ask your pharmacist about a validated, correctly sized cuff
Cholesterol (lipid profile)	LDL, HDL, triglycerides	Contributes to plaque build-up in arteries over decades	Results are read alongside your overall risk, not in isolation
Blood glucose or HbA1c	Blood sugar, short and longer term	Raised glucose is linked to blood vessel changes	Often checked in the same blood test as cholesterol
Waist and weight	Body size and fat distribution	Weight around the waist is linked to cardiometabolic markers	A tape measure trend is more useful than a single reading
Combined risk assessment	Your overall risk, using age, sex, numbers and history	Puts individual numbers in context	In Australia, the Medicare Heart Health Check is available for people aged 45 and over (30 and over for First Nations people); other countries have their own programmes

Who this guidance suits, and who needs a tailored plan

The habits above are general guidance for healthy adults. You need a personal plan from your doctor before changing your activity or diet much if you:

• have a diagnosed heart condition, a pacemaker or a history of stroke
• get chest discomfort, unusual breathlessness, dizziness or palpitations with effort
• take blood pressure, blood-thinning or diabetes medicines
• have kidney disease (relevant to salt and potassium) or have been told to limit fluids

Chest pain, pain spreading to the arm, jaw or back, sudden breathlessness or sudden weakness on one side of the body are emergencies. Call your local emergency number straight away rather than waiting to see if they pass.

A simple weekly heart-health checklist

1. Move most days: add up your moderate activity for the week and work towards 150 minutes, at your own pace.
2. Strength twice: two short sessions of strength work, such as bands, body-weight moves or a class.
3. Break up sitting: stand or walk for a few minutes every half hour or so when you can.
4. Build plates around plants: vegetables, legumes, whole grains, fruit, nuts and fish feature most days.
5. Check salt on labels: compare sodium per 100 grams between similar products and choose the lower one.
6. Protect sleep: a regular wake time and a wind-down routine; mention loud snoring to your doctor.
7. Know your numbers: book blood pressure, cholesterol and glucose checks at the intervals your doctor suggests.
8. Review medicines and supplements: once a year, take everything you use to your pharmacist for a review.

Common mistakes

• Waiting for symptoms. High blood pressure and cholesterol usually feel like nothing at all.
• Assuming it is too late. Fitness, strength and blood pressure still respond to change in later life.
• Going from nothing to hard training. Build up gradually, and get medical advice first if you have a heart condition or symptoms.
• Relying on one food or supplement. The evidence is for overall patterns, not single ingredients.
• Cancelling out exercise with all-day sitting. A morning walk is good; long unbroken sitting afterwards still counts against you.
• Stopping or changing medicines on your own. Lifestyle changes work alongside prescribed medicines; any change to medicines is a conversation with your doctor.

For weekly targets, the talk test and an example build-up plan, see the guide to aerobic exercise for older adults.

Frequently asked questions

What happens to your heart as you get older?

Arteries tend to stiffen, the heart muscle relaxes a little less readily, and maximum heart rate falls. Blood pressure often rises gradually. These are normal changes, but how large they become is linked to habits such as activity, diet, smoking and sleep.

Is it too late to improve heart health at 60 or 70?

No. Training studies in older adults show that fitness and strength still respond to regular activity, and blood pressure responds to changes such as eating less salt. Start gently and build up, and check with your doctor first if you have a heart condition or symptoms.

How much exercise do older adults need for heart health?

The World Health Organization recommends 150 to 300 minutes of moderate activity a week, or 75 to 150 minutes of vigorous activity, plus strength work on two or more days. Older adults are also advised to include balance and strength activities on three or more days. Any amount is better than none.

What is a normal resting heart rate for older adults?

For most adults a resting heart rate between about 60 and 100 beats a minute is considered within the normal range, and it often changes little with age. Fit people may sit lower. A new, unexplained change, or a rate that feels irregular, is worth raising with your doctor.

Does sleep really affect heart health?

Population studies link long-term short or broken sleep with higher blood pressure and poorer cardiovascular markers, and the American Heart Association added sleep to its heart health checklist in 2022. It recommends 7 to 9 hours a night for adults.

Should I take a supplement for my heart?

The strongest evidence is for overall eating patterns, not supplements, and a large Cochrane review found little or no effect of omega-3 capsules on overall deaths or cardiovascular events. Some supplements interact with heart medicines, so talk to your doctor or pharmacist before starting any.

Heart health in later life is not settled by genetics or by choices made decades ago. It builds from ordinary habits, repeated week after week, plus regular checks of the numbers you cannot feel. Pick one item from the checklist this week, and take the rest to your next appointment.
