What is a hot flash?
Symptoms of vasomotor instability associated with menopause are commonly termed "hot flashes". Hot flashes are recurrent, transient episodes of flushing, perspiration and a sensation ranging from warm to intense heat on the upper body and face, sometimes followed by chills. Hot flashes that occur with perspiration during sleep are termed night sweats. The terms hot flash, hot flush and vasomotor symptoms are often used to describe the same phenomenon.[i]
