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.
The hypothalamus is the temperature-regulating centre of the brain. It contains receptors which are sensitive to the temperature of the blood flowing through the brain. Temperature sensitive receptors in the skin also feed back information to the hypothalamus about the temperature of the skin surface.Changes in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature.If the core temperature goes up the body loses heat to bring it down again.hanges in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature.
