You finally lie down. The room is quiet. Your body wants to rest. And then, suddenly, you notice it — your heart feels like it’s racing, pounding, or fluttering just as you’re trying to fall asleep.
For many people, this moment is startling. It can pull you fully awake, spark worry, and make it feel impossible to relax again. If this has been happening to you, it’s important to know this experience is far more common than most people realize.
Heart racing when trying to fall asleep is often a sign of nervous-system activation rather than danger. The sensation feels intense, but it usually reflects how your system is responding to the transition into rest — not a problem with your heart itself.
