AFib in Adults: 5 Lifestyle Shifts That Support a Healthier Heart Rhythm

Atrial fibrillation (AFib) is an arrhythmia that makes your heart's upper chambers beat irregularly, sometimes rapidly. It can make you feel a fluttering or racing sensation in your chest, or you might have no noticeable symptoms at all.

AFib is most commonly diagnosed in older adults, but familial AFib is genetic, and it can be diagnosed in younger adults, teens, and even children. If you’re a young adult living with AFib since adolescence, you know that managing your heart rhythm through medication, monitoring, and lifestyle choices is a lifelong commitment.

Devyani Chowdhury, MD, MHA, and our team at Cardiology Care for Children are ready to help you find habits that fit your needs, whether you’re a teen or a young adult navigating your care. Here are five lifestyle factors that help support a healthy heart rhythm.

1. Establish a consistent exercise routine

Regular physical activity strengthens your heart, which helps regulate heart rate, reduces stress that can trigger AFib episodes, and improves your overall heart function. Most people should aim to get at least 150 minutes of exercise weekly. However, you need to approach exercise thoughtfully with AFib.

If you don’t already have an exercise routine that works for you, talk to our team. Sudden or intense exertion can trigger AFib episodes, so we generally recommend moderate-intensity aerobic activity like brisk walking, cycling, or swimming. These activities improve your heart's efficiency without creating excessive strain on your cardiovascular system.

2. Prioritize stress management

Both emotional and physical stress can trigger AFib episodes in many people. Your nervous system's stress response increases heart rate, and this can precipitate irregular rhythms. That means developing effective stress-management techniques becomes essential for AFib control.

Identify what helps you relax — whether that's time in nature, creative pursuits, or social connection — and prioritize these activities regularly. If you’re not sure where to start, meditation, yoga, and mindfulness practices can help calm your nervous system, promote heart rhythm stability, and reduce AFib frequency.

3. Eliminate or minimize arrhythmia triggers

Caffeine is an AFib trigger for a lot of people. Coffee, tea, energy drinks, and caffeinated sodas increase heart rate and elevate your risk of AFib episodes, so eliminating or drastically reducing caffeine consumption can have a big effect on how you feel.

Alcohol is another common AFib trigger. Even moderate alcohol consumption can trigger AFib episodes, so if you drink alcohol, do so sparingly and monitor your heart's response.

Nicotine from smoking and vaping is another AFib trigger. Nicotine constricts your blood vessels and increases heart rate, while quitting smoking benefits your heart in countless ways.

4. Maintain a heart-healthy diet and weight

A heart-healthy diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats supports cardiovascular health. Limit sodium intake, as excess sodium increases blood volume and can trigger arrhythmias. Maintain healthy electrolyte balance with potassium and magnesium-rich foods, as electrolyte imbalances can worsen AFib.

Your body weight also affects your cardiovascular health, and obesity increases AFib risk and can worsen existing arrhythmias. If you have weight to lose, following a heart-healthy diet and exercising regularly can help you shed those extra pounds to promote your overall well-being.

5. Get quality sleep

Sleep deprivation triggers AFib episodes and worsens heart rhythm stability, so make sure to prioritize sleep as you move beyond your teenage years. Set a goal to get seven to nine hours of consistent, quality sleep nightly. Maintain regular sleep and wake times, keep your bedroom cool and dark, and avoid screens for at least one hour before bed.

Living with AFib means taking a proactive approach to heart care, and you don’t have to navigate it alone.
