Night sweats are episodes of heavy sweating during sleep that soak clothing or bedding. Common causes include a hot bedroom, perimenopause, thyroid overactivity, anxiety, infections, low blood sugar, alcohol and certain medicines.

Frequently asked questions
Are night sweats always menopause?+
No — perimenopause is common but thyroid, infection, anxiety, alcohol and some medicines also cause night sweats. A short blood panel distinguishes them.
When should I worry?+
Weight loss, persistent fever, new lumps or coughing up blood warrant prompt review.
Can Dubai heat cause it?+
A warm bedroom can. Genuine night sweats soak bedding even when the room is cool.
