A sudden wave of heat at night accompanied by sweating, reddening of the skin and increased heartbeat; waking in a cold sweat with wet bed sheets
Decreasing estrogen causes the hypothalamus, a structure in the brain that acts as the body’s thermostat, to become more sensitive to slight changes in body temperature. The brain believes your body is too warm and starts a chain of events to cool you down. When you are asleep, you don’t adjust your clothes or fan yourself like you would with a daytime hot flash, so by the time you wake you are in a full sweat.
