What happens inside your body during a hot flash
Hot flashes are a common experience for many women during perimenopause and menopause. They are characterized by sudden heat surges, often accompanied by sweating and flushed skin, and can last from one to five minutes. The physiological cause involves changes in estrogen levels and the brain's temperature regulation, leading to a hypersensitive response to temperature changes.
