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.

Hyperthermia and Hypothermia Digestive Hyperthermia If heat gain exceeds the ability of the body to lost heat, then body temperature increases above normal levels, a condition called hyperthermia. Hyperthermia can result from exposure to hot environments, exercise, fever, and anesthesia. Exposure to a hot environment normally results in the activation of heat loss mechanisms, and body temperature is maintained at normal levels. This is an excellent example of a negative-feedback mechanism.
