Hot flash

A sudden feeling of feverish heat in the upper body. Hot flashes are one of the symptoms of menopause and on average, persist for more than seven years. Hot flashes can cause flushing, increased heart rate, heavy sweating, cold shivering, and long-term sleep disruptions. Symptoms may be mild or so intense as to disrupt daily activities. Most hot flashes last from 30 seconds to 10 minutes and can occur several times per hour or week.
