Night sweats

Overview

Most people sweat during the night. If you regularly wake up with soaking wet sheets you should get it checked by a GP.

It's normal to sweat during the night if the room or your bedding is making you too hot.

Night sweats are when you sweat so much that your night clothes and bedding are soaking wet, even though where you're sleeping is cool.

Adults and children can get night sweats.

See a GP if you:

If you have night sweats, you will not usually need treatment, but the GP will want to check if you have any other symptoms.

If you're taking medicine and the GP thinks it might be causing night sweats, they may prescribe a different one.

The most common reasons for night sweats are:

menopause symptoms ("hot flushes")
anxiety
medicines - some antidepressants, steroids, painkillers
low blood sugar (hypoglycaemia)
alcohol or drug use
a harmless condition called hyperhidrosis that makes you sweat too much all the time

Sometimes the cause of night sweats is unknown.
