It’s normal to sweat more after you finish exercising than you do while you exercise. Your body temperature varies throughout the day, going from about 97 degrees in the early morning to about 99 degrees in the early evening. Exercise raises body temperature considerably.
More than 70 percent of the energy that powers your muscles is lost as heat, so your body temperature usually rises during exercise. To keep your body temperature from rising too high, your heart pumps the heat in your blood from your muscles to your skin, you sweat and the sweat evaporates to cool your body.
Sweating is controlled by the temperature of the blood flowing to the part of the brain called the hypothalamus. When your temperature rises, you sweat more. During exercise, your heart beats very rapidly to pump extra blood to bring extra oxygen to your muscles and extra hot blood from the muscles to the skin where the heat can be dissipated. When you stop exercising, your heart immediately slows down, decreasing the amount of blood pumped to your skin, so your temperature rises higher which causes you to sweat even more.
