Feeling your heartbeat strongly when lying down is often described as experiencing heart palpitations. This sensation, where you are acutely aware of your heartbeat, can have several causes.
Common Causes of Palpitations When Lying Down
Several factors can contribute to noticing your heartbeat more when lying down:
-
Body Position: Sleeping in certain positions, such as hunched over on your side, can increase internal pressure and make your heartbeat feel more pronounced. Changing positions can often alleviate this. [Source: Some people get heart palpitations when lying down because of the position in which they sleep. Sleeping hunched over on your side can increase pressure inside your body, causing palpitations.]
-
Stress, Anxiety, and Depression: These mental health conditions can significantly impact heart rate and rhythm, leading to noticeable palpitations, especially when resting. [Source: Many other common causes of heart palpitations include: Anxiety, stress and depression.]
-
Stimulants: Consumption of caffeine, nicotine, or alcohol can increase heart rate and make palpitations more noticeable, particularly when lying down and relaxing. [Source: Many factors, including alcohol, caffeine, nicotine, stress or hormones can cause them.]

Vagus Nerve Stimulation: Lying on your left side may stimulate the vagus nerve, influencing your heart rate and potentially causing you to perceive your heartbeat more strongly.

-
Low Abdominal Fat: In individuals with low abdominal fat, the pulse might be more easily felt in the stomach area, particularly when lying down and with knees raised. [Source: You might also feel it if you lie down and raise your knees. And if you don't have much abdominal fat, you may even see your stomach pulse.]
-
Sleeping Position: Sleeping on your back may also increase the likelihood of feeling palpitations due to pressure changes within the body while lying down. [Source: Some experts say people who sleep on their backs may be more likely to feel palpitations because of pressure changes in the body when in bed.]
When to See a Doctor
While often harmless, persistent or severe heart palpitations warrant medical attention. Consult your doctor if you experience:
- Frequent or severe palpitations
- Palpitations accompanied by chest pain, dizziness, or shortness of breath
- Sudden onset of palpitations
