What should you know about sweating profusely at night?

Notice whether sweat soaks sleepwear or bedding, whether the room is hot, and whether episodes occur with fever, cough, itching, palpitations, weight change, or swollen glands. Menopause commonly causes night sweats through changing hormone signals. Hyperthyroidism can also increase heat production and sweating.

Night sweating is a presentation of several conditions, including Brucellosis, Glandular Fever, HIV Infection, Lymphoma, and Hodgkin Lymphoma. This does not mean sweating identifies any one of them; the wider pattern and examination matter.

Keep the bedroom comfortably cool, choose breathable sleepwear, and replace wet clothing or bedding. Drink enough to replace fluid lost overnight. Review medicines, supplements, alcohol, and spicy foods with a clinician rather than stopping prescribed treatment yourself.

Record episode timing, severity, temperature, menstrual or menopause symptoms, new medicines, and associated symptoms. Arrange a routine appointment if the problem recurs or disrupts sleep.

Arrange prompt medical review for drenching sweats that recur, unexplained weight loss, persistent fever, a new lump, ongoing cough, unusual bruising, or significant tiredness. Seek urgent help for breathing difficulty, confusion, fainting, severe weakness, or a rapidly worsening illness.

Ask whether your symptom pattern suggests a hormonal, medication-related, infectious, thyroid, or blood-related cause, and what examination or tests may clarify it.
