A hot flash is a brief feeling of intense warmth and sweating. Hot flashes commonly occur in women around the time of menopause. Researchers do not know exactly what causes hot flashes. Current theories suggest hot flashes are due to a menopause-related drop in the body's level of female hormones called estrogens. This drop affects the hypothalamus, an area of the brain that regulates body temperature.
