What is a hot flash?

Hot flashes refer to a sudden feeling of intense heat that spreads over the upper part of the body and may accompany sweating, flushing, and palpitations. They are a common symptom of hormonal changes, particularly during perimenopause and menopause in women, but can also occur in men with hormonal imbalances. Hot flashes are characterized by a rush of blood to the skin's surface, causing discomfort and sometimes disrupting daily activities.
