SYMPTOM
This is that feeling where your heart seems to thump loudly or beat very fast when you're trying to relax and drift off to sleep. Often, it's down to everyday things like stress, anxiety, or having caffeine too close to bedtime, but it can sometimes signal other issues.
For general awareness only. This is not medical advice. If symptoms are severe or persistent, consult a healthcare professional.
Showing 8 causes
Alcohol rebound effect
After alcohol wears off, your body could have a rebound effect, increasing heart rate and making you feel restless. This disrupts your ability to fall asleep peacefully.
Stress-induced adrenaline release
Stressors trigger your body to release adrenaline, speeding up your heart. You'll feel a racing heart when you're trying to relax.
Residual stimulant effects
Caffeine or other stimulants could keep your nervous system active long after you've consumed them. This makes your heart race even as you try to sleep.
Blood sugar fluctuations
If your blood sugar dips too low, your body releases adrenaline to compensate, speeding up your heart. This could feel like a pounding heart when trying to rest.
Sleep onset palpitations
Your heart could temporarily increase its rate as you transition into sleep. This is often benign and feels like a brief pounding.
Mild dehydration
Not drinking enough fluids makes your blood volume slightly lower, so your heart works harder to circulate it. You may feel your heart pounding as a result.
Arrhythmia episode
A temporary disturbance in your heart's electrical rhythm could cause it to beat too fast or irregularly. This could feel like a noticeable pounding sensation.
Thyroid overactivity
An overactive thyroid gland produces too much thyroid hormone, which speeds up your metabolism and heart rate. This could make your heart pound even when resting.
