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. In a hot flash, the hypothalamus seems to sense that your body is too hot even when it is not, and tells the body to release the excess heat.
During the first two weeks of a woman's cycle, her body temperature is lower (97.0 to 97.5 F), due to the presence of estrogen. With ovulation, a rise in body temperature takes place - caused by an increase of the hormone progesterone - in order to provide a warmer, more fertile environment. A minimum temperature rise of 0.4 to 0.6 degrees F can be measured - and this change will last through the duration of the menstrual cycle.
