What It Actually Means When You Feel Heart Palpitations After Lying Down

Before diving into why you might feel heart palpitations after lying down, let’s clarify what palpitations are. Essentially, they are sensations where you become acutely aware of your heartbeat. You might feel like your heart is pounding, fluttering, or beating irregularly. It’s a common experience and often, it’s not a sign of anything serious.

Why Palpitations Occur When Lying Down

When you lie down, several changes occur in your body that can affect your heart:

1. Change in Blood Flow

Lying down alters the way blood flows in your body. Gravity isn’t pulling blood to your lower body as much, so more blood returns to your heart. This increased volume can temporarily make your heart work harder, potentially causing palpitations.

2. Pressure on the Heart

In some positions, especially on your left side, the weight of your body can press against your heart, making its movements more noticeable. Sleeping in a hunched position on your side can naturally increase pressure inside your body, resulting in heart palpitations.

3. Relaxation and Awareness

When you’re relaxed and quiet, you’re more likely to notice bodily sensations that you might ignore during the hustle and bustle of the day.

Common Causes of Palpitations in This Position

While lying down, certain factors can trigger palpitations:

1. Stress and Anxiety

If you’re stressed or anxious, your body releases adrenaline, which can increase your heart rate and cause palpitations. When you lie down and try to relax, you might become more aware of your stress levels and, consequently, your heartbeat.

2. Indigestion or Acid Reflux

Digestive issues, like acid reflux, can stimulate nerves in the esophagus that are close to the heart, potentially causing palpitations.

3. Hormonal Changes

Hormonal fluctuations, particularly in women during menstruation, pregnancy, or menopause, can cause palpitations.

When to Be Concerned

Most of the time, palpitations are harmless. However, you should pay attention if they’re accompanied by:

These symptoms, especially if they’re new or worsening, warrant a consultation with a healthcare professional.

Managing Palpitations

To manage palpitations, especially at night:

  1. Practice Good Sleep Hygiene: Create a calming bedtime routine and ensure a comfortable sleep environment.
  2. Manage Stress: Techniques like deep breathing, meditation, or gentle yoga can help reduce stress.
  3. Avoid Stimulants: Before bed, steer clear of caffeine, nicotine, and excessive alcohol as they can exacerbate palpitations.
  4. Stay Hydrated: Dehydration can affect your heart rate, so make sure you’re drinking enough water.


While heart palpitations after lying down can be startling, they’re usually not a cause for alarm. However, if you’re concerned or if palpitations are accompanied by other symptoms, it’s wise to seek medical advice. By understanding your body’s responses and maintaining a healthy lifestyle, you can manage these sensations effectively.
