Night sweats, including those from the head, can be caused by a hot bedroom, menopause, infections and some forms of cancer, notes eMedicineHealth. If sweats continue after adjusting bedroom temperature and the bedclothes, seek medical attention.
Women going through menopause often experience hot flashes at night and wake up drenched with sweat, reports eMedicineHealth. Tuberculosis is an infection traditionally connected with night sweating, but other bacterial infections, such as endocarditis, osteomyelitis and some abscesses, cause night sweating, as does HIV infection.
Some cancers, most commonly lymphoma, present with nighttime sweat, notes eMedicineHealth. Other forms of cancer cause night sweats and unexplained weight loss before diagnosis. Some people respond to antidepressant medications with night sweats, and people who take fever medicines, such as acetaminophen or aspirin, can end up sweating at night. Other classes of drugs can cause flushing, a similar condition that involves increased blood flow to the face and upper torso. People who suffer from hypoglycemia, who take medicines for diabetes and who suffer from certain hormone disorders or some neurologic conditions experience night sweats, including from the head. Because of the variety of potential causes, people sweating from the head at night even when the bedroom is cool should visit their primary care physician.
