10 Powerful Ways to Lower Your Heart Disease Risk

The Truth About Heart Disease

Heart disease is the leading cause of death in America, but it rarely develops overnight. Heart disease risk builds over time due to a variety of factors—due to diet, stress, environmental exposures, and other lifestyle habits. While a heart-healthy diet and regular movement are critical, they’re just part of the equation. Nearly everything you do—how you sleep, how you deal with stress, how you move your body—it all determines your risk, so act wisely.

Read on to learn ten key strategies to avoid heart disease and prioritize heart health before problems start.

Why Lifestyle Changes Matter for Heart Health

Medications can help manage conditions like high blood pressure and cholesterol, but they’re not a substitute for consistent healthy habits. A 2024 study highlighted that while medications may help manage stress-related chronic conditions, lifestyle approaches are crucial for long-term stress reduction and cardiovascular health. This means that proactive steps today can significantly reduce your risk of heart disease in the future. Here are those proactive steps:

10 Action Steps to Lower Heart Disease Risk

1. Manage Air Pollution Exposure

Why It Matters

The air you breathe directly impacts your cardiovascular health. Short-term exposure to particulate matter (PM2.5) leads to oxidative stress and inflammation. Long-term exposure has been linked to higher blood pressure, atherosclerosis (plaque buildup), and a greater risk of cardiovascular disease. 

How Air Pollution Affects Your Heart

• Triggers oxidative stress and inflammation
• Raises hs-CRP, triglycerides, and LDL cholesterol while lowering HDL cholesterol
• Can contribute to the damage of arterial lining over time, increasing the risk of heart disease 

How to Reduce Exposure

• Monitor air quality indexes and limit outdoor activities on high-pollution days.
• Use HEPA air filters indoors to reduce exposure to airborne toxins.
• Avoid exercising near high-traffic areas where pollution is highest.
• Incorporate supplements to improve heart health, like CoQ10 and glutathione, to combat oxidative stress caused by air pollution.

2. Reduce Heavy Metal Exposure

Why It Matters

Heavy metals like mercury, lead, and arsenic have been shown to increase blood pressure and raise the risk of heart disease. These metals can accumulate in your system over time, interfering with metabolic processes that support cardiovascular health.

How Heavy Metals Affect Your Heart

• Damages blood vessels
• Increases oxidative stress leading to arterial plaque buildup
• Increases blood pressure

How to Reduce Exposure

• Filter drinking water using a system certified to remove heavy metals.
• Limit consumption of high-mercury fish like king mackerel and swordfish.
• Avoid lead-containing cookware and glassware.

3. Lower Your Stress

Why It Matters

Chronic stress is a silent killer. It raises cortisol levels (the stress hormone), which can increase inflammation and lead to hypertension and insulin resistance. Low levels of DHEA-S (a hormone impacted by stress) have also been linked to higher risk of cardiovascular disease. While you can’t avoid all the stressors of daily life, you can learn to manage them. 

How Stress Affects Your Heart

• Elevates cortisol and blood pressure
• Increases inflammation and arterial stiffness

How to Manage Stress

• Practice mindfulness techniques like deep breathing, yoga, or meditation—they’re proven to lower stress and cardiovascular risk.
• Exercise regularly to counteract stress and increase emotional resilience^.
• Strengthen social connections. 

4. Invest in Your Relationships

Why It Matters

Loneliness isn’t just emotional—it’s physical. Poor social connections are associated with a 29% higher risk of heart disease and a 32% higher risk of stroke. Strong relationships are powerful—they lower inflammation and reduce stress. If you care about your long-term health, relationships are essential to cultivate.

How Relationships Impact Heart Health

• Lowers stress hormones, which impact blood vessel function
• Reduces inflammation measured by hs-CRP, helping reduce heart disease risk

How to Strengthen Relationships

• Prioritize meaningful social interactions—schedule an activity with friends or invite loved ones over for dinner.
• Join community groups or engage in volunteer work—shared interests are a good way to spark up meaningful connections.

5. Improve Your Sleep

Why It Matters

Sleep issues are linked to a 75% higher risk of heart disease, a 105% higher risk of heart attack, and a 78% higher risk of stroke. Poor sleep affects cholesterol, blood sugar, and inflammation levels, disrupting the body’s natural ability to repair and regenerate.

How Poor Sleep Impacts Heart Health

• Disrupts glucose and insulin sensitivity
• Increases chronic inflammation (indicated by elevated hs-CRP)—a risk factor for heart disease
• Lowers HDL cholesterol and raises triglycerides

How to Improve Sleep

• Stick to a consistent bedtime schedule.
• Limit screen time and blue light exposure at least 30 minutes before bed.
• Reduce caffeine and alcohol intake in the evening.
• Consider incorporating magnesium to support sleep quality.

6. Stop Smoking

Why It Matters

Smoking can damage the cells that line blood vessels, decrease HDL cholesterol (good cholesterol), significantly raising heart disease risk. The good news? Quitting smoking can reduce heart attack risk in as little as a day.

How Smoking Impacts Heart Health

• Increases apolipoprotein B (ApoB), LDL cholesterol, and triglycerides—all indicators of heightened heart disease risk
• Lowers HDL cholesterol

How to Quit Smoking

• Seek professional support and nicotine replacement therapies.
• Join a smoking cessation program.
• Replace smoking habits with healthier stress management techniques.

7. Cut Out Sugary Drinks

Why It Matters

They’re more than a sweet treat—just one extra sugary drink a day increases heart disease risk by 19%. The risks are real. These beverages can fuel inflammation, disrupt blood sugar, and contribute to obesity—all major risk factors for heart disease.

How It Impacts Heart Health

• Increases glucose and insulin levels
• Can elevate inflammatory markers like hs-CRP
• Lowers HDL cholesterol (good cholesterol)
• Raises triglycerides

How to Reduce Sugary Drink Consumption

• Swap soda for sparkling water with fresh fruit.
• Choose unsweetened (herbal) teas.
• Gradually reduce sugar intake to avoid cravings.

8. Practice Meditation

Why It Matters

Meditation isn’t just for relaxation—it’s a powerful tool for cardiovascular health. A 2020 study published in the American Journal of Cardiology found that people who meditated had significantly lower rates of cardiovascular risk factors compared to those who did not. Meditation can lower blood pressure, improve heart rate variability, and reduce the risk of cardiovascular disease.

How Meditation Impacts Heart Disease Risk

• 51% lower risk of coronary artery disease
• 35% lower risk of high cholesterol
• 30% lower risk of diabetes
• 24% lower risk of stroke
• 14% lower risk of high blood pressure

How to Incorporate Meditation

• Start with 5-10 minutes daily and gradually increase.
• Use guided meditation apps for relaxation and stress reduction.
• Practice mindful breathing and focus on deep, slow breaths to regulate heart rate.

9. Eat for Heart Health

Why It Matters

What you eat shapes your future health. A heart-healthy diet has been found to support cholesterol balance, reduce inflammation, reduce blood pressure, and regulate blood sugar—all factors that impact your heart disease risk. 

How to Eat a Healthy Diet for a Healthy Heart

Prioritize heart-healthy foods, such as:

• Whole, nutrient-dense fruits, vegetables, whole grains, and legumes.
• Healthy fats like olive oil and nuts.
• Limit processed foods and refined sugars.
• High-quality sources of lean protein like fish and organic poultry.
