Is night sweats a sign of perimenopause?
Severe hot flashes that occur during sleep and can cause heavy sweating.
Why it happens
Estrogen fluctuations disrupt the hypothalamus -- your brain's internal thermostat -- causing it to misread normal body temperature as dangerously high. The result is a sudden night sweats as your body attempts to cool itself. These episodes can occur dozens of times a day and are one of the strongest predictors of cardiovascular risk later in life.
