Nighttime heart flutters (nocturnal palpitations) are often caused by benign arrhythmias triggered by stress, caffeine, alcohol, dehydration, poor sleep posture, or undiagnosed sleep apnea. Acute episodes can typically be calmed with deep breathing, the Valsalva maneuver, position changes, hydration, or relaxation techniques.
Long-term relief involves diagnosing and treating sleep apnea (CPAP, oral appliances, weight management), improving sleep hygiene, optimizing diet, managing stress, and exercising regularly. However, causes vary widely—and some heart flutters warrant closer medical attention.
Because palpitations can range from harmless to serious, the smartest next step is understanding your specific symptoms. Take a free, instant, AI-powered symptom check to identify possible causes, gauge urgency, and get personalized guidance on what to do next—no signup required.

Heart flutters—also known as palpitations—are a common complaint, especially when you're trying to rest. Feeling like your heart is skipping beats, racing or pounding in the middle of the night can be alarming. While most episodes are harmless, they can still disrupt your sleep and cause anxiety. This guide explains why these palpitations happen, how sleep apnea can trigger them, and practical steps to calm your heart at night.
Heart flutters or palpitations are sensations that your heart is:
These sensations often stem from benign arrhythmias—non-life-threatening irregularities in heart rhythm. At night, you're more aware of these sensations because external distractions are minimal.
Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. Each pause in breathing temporarily lowers the oxygen level in your blood. To restart breathing, your heart may beat faster or irregularly, causing palpitations.
By treating sleep apnea effectively, you'll likely see a decrease in nighttime heart palpitations.
If you're lying awake with palpitations, try these simple techniques:
These steps may help halt flutters quickly, but they're not a substitute for medical evaluation if episodes persist.
Beyond immediate relief, adopting heart-healthy habits can reduce the frequency of nighttime palpitations:
