In summer, when out side temperature is more than our body temperature, we sweat profusely. The resulting evaporative cooling, similar to what happens with a desert cooler in operation, brings down the body temperature. In winter when the temperature is much lower $37^o C$, we start to shiver a kind of exercise which produce heat and raises the body temperature. They are called.
