Keep Your Heart Young: How to Know If It's Aging Too Fast — And What to Do About It

By Lilla Fonyo — Healthy Lifestyle & Longevity Writer

Last update March 2026

Quick Summary

Your heart age may not match your actual age. Many people have hearts that are several years older than they are, which increases the risk of heart disease and stroke. The good news is that simple lifestyle changes — such as improving your diet, moving more, managing stress and stopping smoking — can help protect your heart and even slow down its ageing process.

Why Heart Age Matters

When we talk about ageing, we usually think about our chronological age — the number of years we’ve been alive. But doctors are increasingly interested in something called “heart age”, which reflects how healthy your cardiovascular system really is.

Research from Northwestern University’s Feinberg School of Medicine suggests that many adults have hearts that are four to seven years older than their actual age. When the heart ages faster than the rest of the body, the risk of conditions such as heart disease, stroke and high blood pressure rises significantly.

According to cardiologist Dr Sadiya Khan, several common lifestyle factors can accelerate heart ageing, including:

High blood pressure

High cholesterol

Physical inactivity

Poor diet

Long-term stress

These factors place extra strain on the heart and blood vessels over time.

Understanding Your Heart Age

Traditionally, doctors estimate cardiovascular risk using percentages — for example, the likelihood of having a heart attack within the next ten years. However, these figures can be difficult for many people to interpret.

To make the information easier to understand, researchers developed a heart age calculator that translates risk into an estimated “age” for your heart. The idea is simple: if your heart age is higher than your actual age, your cardiovascular risk may be higher too.

A study of more than 14,000 adults aged 30 to 79 found:

Women’s hearts were typically around four years older than their real age

Men’s hearts were around seven years older

In some groups, particularly those facing economic or educational disadvantages, heart age could be up to ten years older

Knowing your heart age can help motivate positive lifestyle changes.

Simple Ways to Keep Your Heart Young

Fortunately, heart health is highly responsive to everyday habits. Even small changes can make a meaningful difference over time.

1. Stop Smoking

Smoking is one of the most harmful habits for the heart. Chemicals in cigarette smoke damage blood vessels, raise blood pressure and increase the risk of blood clots. Quitting smoking is one of the most effective steps you can take to protect your cardiovascular health.

2. Move More Every Day

Physical activity strengthens the heart and improves circulation. You don’t need intense workouts to benefit — walking, gardening or taking the stairs all count. Even adding a few hundred extra steps per day can support long-term heart health.

3. Eat a Balanced Diet

Focus on whole, nutrient-rich foods such as:

Fruit and vegetables

Whole grains

Beans and legumes

Healthy fats like olive oil and oily fish

Try to limit processed foods, added sugars and foods high in saturated fat.

4. Build Strength

Strength training exercises such as squats, push-ups or resistance workouts can support both muscle health and cardiovascular fitness.

5. Manage Stress

Long-term stress can increase blood pressure and strain the cardiovascular system. Practices such as meditation, yoga, breathing exercises or spending time outdoors can help reduce stress levels.

6. Stay Connected

Strong social relationships are linked with better mental health and lower stress levels. Even short conversations with friends or family can have positive effects.

What If Your Heart Age Is Healthy?

If your heart age is close to — or even younger than — your actual age, that’s great news. But maintaining heart health still requires ongoing care.

Healthy habits such as regular activity, a balanced diet, stress management and good sleep help preserve cardiovascular health over the long term.

What the NHS Says About Heart Health

The National Health Service (NHS) highlights several key risk factors that can damage the heart and blood vessels over time.

Smoking

Smokers are almost twice as likely to have a heart attack compared with people who have never smoked. Tobacco chemicals damage artery walls and reduce the blood’s ability to deliver oxygen to the body.

Physical Inactivity

The heart is a muscle and needs regular activity to stay strong. According to global health recommendations, adults should aim for:

150 minutes of moderate activity per week, or

75 minutes of vigorous activity, plus

Strength training on at least two days each week.

Regular activity helps control blood pressure, cholesterol and body weight.

High Blood Pressure

High blood pressure can damage artery walls and make it easier for fatty deposits to build up, increasing the risk of heart attacks and strokes. Because it often has no symptoms, regular checks are essential.

Diabetes

High blood sugar can inflame blood vessels and increase the likelihood of plaque build-up in the arteries. Managing weight, diet and physical activity helps reduce this risk.

Guidance from the British Heart Foundation

The British Heart Foundation (BHF) emphasises the importance of a balanced diet for protecting cardiovascular health.

Key recommendations include:

Eating at least five portions of fruit and vegetables per day

Choosing wholegrain carbohydrates such as wholemeal bread or brown rice

Including beans, pulses and fish as healthy protein sources

Limiting foods high in salt, sugar and saturated fat

Choosing healthier fats such as olive or rapeseed oil

The BHF also encourages gradual, sustainable dietary changes rather than strict diets that are difficult to maintain.

What PubMed Research Says About Heart-Healthy Diets

Scientific research strongly supports the role of nutrition in preventing cardiovascular disease.

A review published in PubMed (PMID: 37113563) highlights that lifestyle changes — particularly diet — are among the most effective strategies for reducing cardiometabolic risk factors.

Researchers found that diets rich in:

Fruits and vegetables

Whole grains

Legumes

Lean protein sources

are consistently linked to better heart health.

Several dietary patterns show particularly strong evidence, including:

Mediterranean diet

DASH diet (Dietary Approaches to Stop Hypertension)

Plant-based diets

These eating patterns emphasise whole foods while limiting processed foods, trans fats and sugary drinks.

The research also suggests that diet may influence gut microbiome health, which could play an emerging role in cardiovascular disease prevention.

Takeaway

Your heart doesn’t have to age faster than the rest of your body. By adopting simple lifestyle habits — such as staying active, eating a balanced diet, managing stress and avoiding smoking — you can significantly reduce your risk of heart disease and help keep your heart healthy for years to come.

Small, consistent changes today can make a powerful difference to your long-term heart health.

❓ FAQ: Keep Your Heart Young

What does “heart age” mean?

Heart age is an estimate of how healthy your heart and blood vessels are compared with your actual age. If your heart age is higher, your risk of cardiovascular disease may be increased.

How can I check my heart health?

Regular health checks with your GP can measure important indicators such as blood pressure, cholesterol, blood sugar and weight. These factors help estimate your cardiovascular risk.

Can lifestyle changes really reduce heart disease risk?

Yes. Research suggests that up to 80% of heart disease cases could be prevented through lifestyle changes such as healthy eating, regular physical activity and not smoking.

How much exercise does my heart need?

Most health guidelines recommend at least 150 minutes of moderate exercise per week, such as brisk walking, cycling or swimming.

Does stress affect the heart?

Yes. Long-term stress can raise blood pressure and contribute to unhealthy habits such as overeating, smoking or poor sleep, all of which can increase cardiovascular risk.

Which foods are best for heart health?

Foods that support heart health include fruit, vegetables, whole grains, beans, nuts, seeds, fish and healthy oils such as olive oil.
