Can anxiety make your heart race at night?

Yes. Anxiety switches on the body’s stress response, which raises your heart rate, and in a quiet, dark room you’re much more likely to notice it. Noticing it can then cause more worry, which keeps your heart rate up. Because a racing heart can also have medical causes, get checked by a doctor, especially if it’s new. If anxiety turns out to be part of it, therapy can help break the cycle.

Is it normal for your heart to race at night?

Noticing your heartbeat more at night is something many people experience, because the quiet and stillness make every beat easier to feel. A racing heart can come from anxiety, caffeine, alcohol, or a heavy evening meal, and it can also have physical causes that need checking. So even if it feels familiar, mention it to your doctor, especially if it’s new or getting more frequent. If anxiety is part of it, a therapist can help.

Why does my heart pound as soon as I lie down?

Lying down takes away the distractions that kept you from noticing your heartbeat during the day, and the position itself can make it easier to feel. If you’re already anxious, noticing it can set off a worry that something is wrong, which speeds your heart further. Mention it to your doctor so they can check for physical causes. If it’s anxiety, a therapist can teach you ways to respond to the sensation without it spiraling.

When should I go to the ER for a racing heart?

Get emergency care right away if a racing heart comes with chest pain or pressure, fainting or nearly fainting, severe shortness of breath, or if it doesn’t settle. In those situations, don’t wait to find out whether it’s anxiety. For episodes that aren’t an emergency, book a visit with your doctor to get checked, even if the episodes pass on their own.

Can therapy stop my heart racing at night?

When anxiety is part of it, a therapist can help you understand what’s driving the episodes and find ways to respond to them, alongside your doctor’s care once physical causes are ruled out. Therapists often use approaches like CBT, including techniques for getting used to physical sensations. On Alma, you can search for therapists who treat anxiety and panic and take your insurance.

The short answer

A racing heart at night is often caused by anxiety: as the day quiets down, the stress response can surge, raising your heart rate and making it more noticeable in the stillness. Caffeine, alcohol, and poor sleep add to it. Because a racing heart can also have physical causes, see a doctor to rule those out, then a therapist can help with the anxiety driving it.

What a racing heart at night can feel like

It often hits as you lie down: a pounding or fluttering chest, a pulse you can suddenly hear, maybe a wave of dread that something is wrong. The quiet makes every beat louder, which ramps the worry, which speeds the heart further.

For many people this is the physical side of anxiety rather than a heart problem, but because the two can feel identical, it’s always worth taking seriously rather than dismissing.
