Heart palpitations – those unsettling moments when you can feel or hear your own heartbeat—can be alarming. Whether it’s a pounding sensation in your chest or a rhythmic thumping in your ears, understanding why this happens is essential. Here are seven reasons why you might experience heart palpitations, as explained by cardiologists.
1. Physical Exercise
Feeling your heartbeat during physical activity is normal and expected. Dr. Anjali Dutta, a cardiovascular specialist, explains that during exercise, your heart rate increases to pump more blood and oxygen to your muscles.1 This increased demand causes the heart to beat faster, which can be felt as pounding in the chest, especially during intense workouts. However, if you experience additional symptoms like chest pain or dizziness, it’s advisable to consult a doctor.
2. Stress and Anxiety
Emotional stress and anxiety are common triggers for heart palpitations. Dr. Sam Setareh, a cardiologist, notes that stress and anxiety can lead to an adrenaline rush, causing your heartbeat to be quicker and more forceful. This response is part of the body’s natural “fight or flight” mechanism. If you frequently experience palpitations during stressful times, relaxation techniques like deep breathing, yoga, or meditation can help manage them.2
3. Dehydration and Electrolyte Imbalances
Dehydration can lead to a decrease in blood volume, making the heart work harder to pump blood, resulting in palpitations. Dr. Setareh also points out that imbalances in electrolytes, like magnesium and potassium, can affect heart rhythm. Ensuring you stay hydrated and maintaining a balanced diet rich in these nutrients can help prevent palpitations.
4. Sleep Position
Interestingly, the way you sleep can also affect your heart. Dr. Setareh mentions that sleeping in a curled or bent position can increase internal pressure, leading to heart palpitation. This is particularly noticeable when lying on your side. If you frequently feel your heartbeat while lying down, consider adjusting your sleeping posture.

5. Consumption of Stimulants
Caffeine, nicotine, and certain medications can stimulate your heart, leading to palpitations. These substances increase your heart rate and can cause irregular heartbeats. Reducing intake of these stimulants can help manage and reduce the frequency of palpitations.
6. Medical Conditions
Various medical conditions can cause heart palpitations. These include anemia, thyroid disorders, low blood sugar, and heart disease. According to Dr. Dutta, people with these conditions may experience palpitations more frequently. Regular medical check-ups and managing these underlying conditions are crucial in preventing palpitations.
7. Pulsatile Tinnitus
If you hear your heartbeat in your ear, it could be due to a condition known as pulsatile tinnitus. Dr. Setareh explains that this rare form of tinnitus causes individuals to hear their pulse in their ear, often in sync with their heartbeat. While it can be benign, it’s essential to consult a doctor for a thorough evaluation to rule out any serious conditions.
When to See a Doctor
While heart palpitations are usually harmless, certain symptoms should prompt a visit to a healthcare provider. These include persistent palpitations, dizziness, chest pain, shortness of breath, and fainting. If you experience these symptoms, it’s essential to seek medical advice promptly.
Understanding the reasons behind feeling or hearing your heartbeat can help alleviate concerns and guide you in managing your heart health effectively. Always consult with a healthcare professional if you have any doubts or persistent symptoms.
