In women, the decline in ovarian function and lower levels of oestrogen during menopause can cause night sweats during sleep. In addition, night sweats can be associated with a variety of factors such as postnatal deficiency, hyperthyroidism, rheumatic fever, tuberculosis and anxiety disorders. If a female patient experiences night sweats with other clinical symptoms, it is advisable to visit a hospital in a timely manner so that the cause can be identified and treated early.
