Hot flashes are a form of flushing due to reduced levels of estradiol.

They are typically experienced as a feeling of intense heat with sweating and rapid heartbeat, and may typically last from 2 to 30 minutes for each occurrence.

Hot flashes, a common symptom of menopause and perimenopause, are typically experienced as a feeling of intense heat with sweating and rapid heartbeat, and may typically last from two to thirty minutes for each occurrence, ending just as rapidly as they began. The sensation of heat usually begins in the face or chest, although it may appear elsewhere such as the back of the neck, and it can spread throughout the whole body. Some women feel as if they are going to faint. In addition to being an internal sensation, the surface of the skin, especially on the face, becomes hot to the touch. This is the origin of the alternative term 'hot flush', since the sensation of heat is often accompanied by visible reddening of the face. Excessive flushing can lead to rosacea.
