How to Lower Resting Heart Rate with Diet & Exercise

Your resting heart rate (RHR) — the number of heartbeats per minute when your body is at complete rest — can reveal much about your cardiovascular health. A lower RHR generally indicates more efficient heart function and better cardiovascular fitness. Most adults’ normal resting heart rate ranges from 60 to 100 beats per minute. However, athletes or physically active individuals may have a lower RHR, often as low as 40 bpm. If your resting heart rate is on the higher side, you can take actionable steps to bring it down naturally. Two of the most effective ways are through diet and exercise. Let’s explore how these lifestyle changes can help you support a healthier heart.

Why Resting Heart Rate Matters

A consistently high RHR can be a sign of increased stress on the heart and may raise the risk of heart disease, stroke, and other complications. Lowering your resting heart rate, on the other hand, is linked to improved heart efficiency, reduced blood pressure, and a decreased risk of cardiovascular events. That’s why managing it through sustainable changes is a smart long-term health goal.

Exercise: The Fastest Natural Way to Lower RHR

1. Aerobic (Cardio) Exercise

Regular aerobic exercise is the most effective way to reduce your resting heart rate over time. Activities like walking, jogging, cycling, swimming, or dancing condition the heart muscle, allowing it to pump more blood with each beat. This efficiency means your heart doesn’t have to work as hard when you’re at rest.

  • Aim for at least 150 minutes of moderate aerobic activity per week.
  • Start slow if you’re new to exercise and gradually increase intensity.
  • Use interval training for a greater impact — alternating between high and low intensity can improve heart rate variability and endurance.

2. Strength Training

While cardio directly improves cardiovascular endurance, strength training complements it by improving muscle function, insulin sensitivity, and overall metabolic health.

  • Incorporate strength training 2–3 times a week, targeting major muscle groups.
  • This helps balance your exercise routine and further supports a healthy RHR.

3. Stretching and Recovery

Stretching, yoga, and breathing exercises support the nervous system, particularly the parasympathetic (“rest and digest”) system, which helps regulate and lower your resting heart rate.

  • Practicing deep breathing or meditation for 10–15 minutes daily can calm your nervous system.
  • Gentle yoga sessions improve flexibility and support relaxation.

Diet: Fueling a Heart-Friendly Lifestyle

The foods you eat can significantly impact your resting heart rate by influencing blood pressure, cholesterol, and inflammation levels.

1. Eat More Omega-3s

Fatty acids found in fish like salmon, mackerel, and sardines — or plant sources like flaxseeds and chia seeds — help reduce inflammation and improve heart rhythm.

  • Eat fatty fish 2–3 times a week or take an omega-3 supplement if advised by a doctor.
  • Walnuts and algae-based omega-3 supplements are great plant-based options.

2. Focus on Whole, Plant-Based Foods

A diet rich in vegetables, fruits, legumes, nuts, and whole grains supports heart health and keeps the cardiovascular system functioning efficiently.

  • Foods high in potassium (like bananas, spinach, and sweet potatoes) help control blood pressure and ease strain on the heart.
  • Fiber from whole foods helps manage cholesterol and body weight, both of which influence RHR.

3. Reduce Processed and Sugary Foods

Highly processed foods, trans fats, excess salt, and added sugars can increase inflammation and contribute to high blood pressure, thereby raising your resting heart rate.

  • Limit fast foods, sugary snacks, sodas, and refined carbs.
  • Replace these with healthier snacks like fruit, nuts, yogurt, or hummus.

4. Stay Hydrated

Even mild dehydration can make your heart work harder to pump blood, which may elevate your resting heart rate.

  • Drink at least 8 glasses of water daily, more if you exercise or live in a hot climate.
  • Herbal teas and water-rich foods like cucumbers and watermelon also help.

Other Supportive Lifestyle Habits

While diet and exercise form the foundation of lowering resting heart rate, a few other habits can also make a big difference.

1. Get Quality Sleep

Poor or insufficient sleep can spike your resting heart rate due to increased stress hormones and reduced recovery.

  • Aim for 7–9 hours of quality sleep each night.
  • Maintain a consistent bedtime and limit screen time before bed.

2. Manage Stress Levels

Chronic stress activates the sympathetic nervous system, increasing heart rate and blood pressure.

  • Practice mindfulness, journaling, or light nature walks to decompress.
  • Avoid overworking and build time for rest into your routine.

3. Avoid Excessive Caffeine and Alcohol

Both substances can elevate heart rate and interfere with sleep and hydration.

  • Limit caffeine to 1–2 cups of coffee per day and monitor how your body reacts.
  • Keep alcohol intake moderate or eliminate it if it spikes your heart rate.

When to Seek Medical Advice

If your resting heart rate is consistently above 100 bpm or below 50 bpm (and you’re not an athlete), you should consult a healthcare provider. Sometimes, an abnormal RHR can be a symptom of an underlying health condition such as thyroid disorders, arrhythmias, or anemia.
