Unhealthy Habits Speed Up Heart Aging — Here’s How To Keep Your Heart Young

Your heart’s biological age — how well it’s functioning — can be much older than your actual years if unhealthy habits take over. New research shows that factors like high blood pressure, diabetes, obesity, and smoking can speed up the aging of your heart, increasing the risk of heart disease and stroke.

But here’s the good news: by adopting heart-smart lifestyle changes, you can slow down this process, improve your heart’s “functional age,” and add quality years to your life.

What Is “Heart Age” — And Why It Matters

Doctors are increasingly using the concept of “heart age” — an estimate of how old your heart really is based on health measures — to predict your risk for heart problems. This goes beyond just counting your chronological age in years.

For example, a new “heart age” calculator called PREVENT (published in JAMA Cardiology) factors in blood pressure, cholesterol, kidney health, smoking status, diabetes, and more to give a personalized heart age estimate. Researchers found that most Americans’ hearts are older than their actual age, signaling the urgent need for lifestyle changes.

Another exciting breakthrough uses cardiac MRI scans to measure the heart’s “functional age” by assessing how well the heart’s left atrium contracts and pumps blood. This method identifies early signs of heart disease before symptoms appear — a true game-changer in cardiology.

Signs Your Heart Might Be Aging Too Fast

As we get older, some changes in the heart are normal, such as:

Occasional extra heartbeats or skipped beats (usually harmless unless persistent)
Enlarged heart chambers with thicker walls, reducing blood volume capacity
Increased risk of arrhythmias like atrial fibrillation, which raise stroke risk
Thickening and stiffening of heart valves, which can limit blood flow or cause leaks

However, these changes can happen prematurely if you have certain health conditions or unhealthy habits.

What Causes Premature Heart Aging?

According to the CDC and recent research, four main factors speed up heart aging:

High Blood Pressure (Hypertension): Forces the heart to work harder, thickening the heart muscle and increasing heart attack risk.
Diabetes: High blood sugar damages blood vessels, promoting plaque buildup that blocks blood flow.
High LDL (“Bad”) Cholesterol: Leads to artery plaque buildup, restricting circulation to the heart and other organs.
Obesity: Often linked with hypertension and high LDL, making the heart’s job even tougher.

Unhealthy lifestyle choices like smoking and physical inactivity also accelerate this process, making your heart age faster than your body.

How to Keep Your Heart Young: Expert Tips

While measuring heart age is still an evolving science, you can take control today by following heart-healthy habits recommended by the American Heart Association’s Life’s Essential 8 and other experts:

1. Get Moving: Exercise for Heart Longevity

Aim for at least 150 minutes of moderate aerobic activity weekly (like brisk walking) or 75 minutes of vigorous exercise (like running), combined with strength training twice a week.

Sitting too much can harm your heart even if you exercise regularly. To keep your blood flowing and arteries healthy:

Take regular walking breaks during your workday
Use the stairs instead of the elevator
Dance, garden, or play a sport you love
Try yoga or simple stretches

Regular movement lowers blood pressure, improves circulation, reduces inflammation, and helps manage weight.

2. Eat a Heart-Smart Diet

Focus on whole, unprocessed foods rich in nutrients and fiber:

Vegetables and fruits: Loaded with vitamins, antioxidants, and minerals
Whole grains: Such as brown rice, quinoa, and oats
Lean proteins: Skinless poultry, fish (especially fatty fish rich in omega-3s), legumes, nuts, and seeds
Healthy fats: Extra-virgin olive oil, avocado oil, nuts, and fatty fish

Limit processed meats, fast foods, and ultra-processed snacks high in trans fats and sodium, which harm your heart.

Stay hydrated with water; unsweetened coffee and tea are also good choices.

3. Quit Smoking and Avoid Secondhand Smoke

Smoking raises blood pressure and damages blood vessels, reducing oxygen flow and accelerating heart damage. Quitting smoking is one of the most effective ways to improve heart health.

4. Limit Alcohol Intake

Stick to moderate alcohol consumption: no more than one drink per day for women and two for men. Excessive drinking increases risks of stroke and other heart problems.

Some individuals may benefit from avoiding alcohol altogether due to cancer risk and heart health concerns.

5. Manage Stress and Prioritize Mental Health

Mental wellbeing and heart health are deeply connected. Chronic stress, anxiety, and depression increase heart disease risk, while social isolation compounds the problem.

Incorporate stress-reducing activities like:

Engaging in hobbies you love
Spending time with friends, family, or pets
Laughing and enjoying lighthearted moments
Practicing mindfulness, meditation, or deep breathing

The Bottom Line: Take Charge of Your Heart Age Today

Your heart’s biological age may tell a different story than your birth certificate. But with the right lifestyle choices, you can slow down heart aging, prevent complications, and live a vibrant life.
