Heart Palpitations at Night During Menopause
Heart palpitations at night during menopause are common — and terrifying if you don't know what they are. You lie down to sleep and suddenly your heart feels like it's pounding, racing, or skipping beats. You wonder if you're having a heart attack.
In the vast majority of cases, you're not. Heart palpitations are a recognised symptom of perimenopause and menopause, caused by the same hormonal shifts that trigger hot flushes and night sweats. Oestrogen affects how your heart responds to the signals that control its rhythm, and when oestrogen fluctuates, palpitations can result.
Why menopause causes heart palpitations
Oestrogen has a protective effect on your cardiovascular system. It helps regulate heart rate and blood vessel tone. When oestrogen levels drop during perimenopause, your heart can become more sensitive to adrenaline and other stress hormones.
This is why palpitations often happen at night — your body is winding down, but your nervous system is in a state of mild overdrive due to hormone fluctuations. When you lie still and there are no distractions, you become acutely aware of your heartbeat. What was always happening in the background suddenly becomes loud and noticeable.
When to take palpitations seriously
Menopause-related palpitations are typically brief — lasting a few seconds to a few minutes — and come and go. They're not a sign of heart disease on their own.
However, you should see a doctor if your palpitations are accompanied by: chest pain, shortness of breath, dizziness, fainting, or palpitations that last more than a few minutes and don't stop. These could indicate a heart condition that needs investigation, regardless of menopause.
If you have no other symptoms and your doctor has cleared your heart, then the palpitations are almost certainly hormonal.
What helps reduce nighttime palpitations
Cut caffeine completely — not just in the evening. Caffeine stimulates adrenaline, and your heart is already more sensitive to adrenaline during perimenopause. Many women find that palpitations disappear entirely once they stop caffeine.
Manage stress and anxiety. Cortisol and adrenaline drive palpitations. Simple breathing exercises before bed — specifically 4-7-8 breathing or box breathing — can calm your nervous system and reduce nighttime heart awareness.
Avoid heavy meals and alcohol before bed. Both can trigger palpitations by affecting blood flow and heart rate during digestion.

Frequently Asked Questions
Are heart palpitations a menopause symptom?
Yes. Heart palpitations are a recognised symptom of perimenopause and menopause, caused by fluctuating oestrogen levels affecting your heart's sensitivity to stress hormones. They're common and, in the absence of other symptoms, not dangerous.
When should I worry about heart palpitations at night?
See a doctor if palpitations are accompanied by chest pain, shortness of breath, dizziness, fainting, or if they last more than a few minutes. If your doctor has cleared your heart and you have no other symptoms, they're most likely hormonal.
Can caffeine cause heart palpitations during menopause?
Yes. Caffeine stimulates adrenaline production, and your heart becomes more sensitive to adrenaline during perimenopause due to dropping oestrogen. Many women find that eliminating caffeine significantly reduces or eliminates palpitations.
