Night sweats

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

What night sweats are

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.

Non-urgent advice: See a GP if you:

  • have night sweats regularly that wake you up or you're worried
  • also have a very high temperature (or feel hot and shivery), a cough or diarrhoea
  • have night sweats and you're losing weight for no reason

Treatment from a GP

Often you won't need treatment, but your GP will want to check if you have any other symptoms.

If your GP thinks your medicine might be causing night sweats you could be prescribed a different one.

Causes of night sweats

The most common reasons for night sweats are:

  • menopause symptoms ("hot flushes")
  • anxiety
  • medicines – some antidepressants, steroids and 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.
