Why do I get night sweats?
Last updated September 3, 2026.
Night sweats means soaking through nightclothes and bedding in a cool room - and the usual causes are menopause hot flushes, anxiety, medicines like some antidepressants and steroids, low blood sugar, or alcohol. The check-it lines are sweats plus fever, cough, diarrhoea, or weight loss without trying. Pymander is a free AI doctor, 24/7 by text, and can help you map your pattern.
What to do
- Rule out the room first: heavy duvet and warm bedroom mimic night sweats.
- Review your medicines with a GP or pharmacist - several common ones list night sweats.
- Keep a two-week diary: sweats, alcohol, stress, and any other symptoms.
- Sweats plus fever, cough, diarrhoea, or weight loss? Book a GP visit.
