what causes sweating at night

Night sweats can be caused by a variety of factors, including medications, hormonal changes, stress, sleepwear and sleep environment, and underlying medical conditions. Drinking before bedtime, stress levels, and sleepwear and sleep environment can all contribute to variations in body temperature while sleeping, which can lead to sweating. In some cases, night sweats can be a sign of a medical condition or disease, such as autoimmune disorders, infections, or some kinds of cancer. If night sweats are accompanied by other concerning symptoms, such as fever, weight loss, pain in a specific area, cough, or diarrhea, it is important to see a doctor. Depending on the cause of night sweats, wearing loose-fitting pyjamas made of natural fibres such as cotton or linen, using lightweight bedding, and avoiding spicy foods or hot drinks before bedtime may help reduce sweating while sleeping.
