    Cold skin
Description:
The skin is used to regulate the temperature of the body. When the body is cold, hairs on the skin stand on end to try and trap air around them, in an effort to better insulate the body. Blood vessels also shrink away from the skin's surface in order to retain their heat. This is known as vasoconstriction.
