If the skin temperature drops below 37C a variety of responses are initiated to conserve the heat in the body and to increase heat production.

Body temperature is regulated by a system of sensors and controllers across the body. The brain receives signals regarding body temperature from the nerves in the skin and the blood. These signals go to the hypothalamus, which coordinates thermoregulation in the body. Signals from the hypothalamus control the sympathetic nervous system, which affects vasoconstriction, metabolism, shivering, sweating, and hormonal controls over temperature
