*[[Erector Muscle|Erector muscles]] relax allowing the body hairs to lie flat on the [[skin]].
*[[Blood Vessel|Blood vessels]] near the surface of the [[skin]] [[dilate]] to allow more of the warm [[blood]] to pass its [[Thermal Energy Store|thermal energy]] on to the [[skin]].
*[[Sweat Gland|Sweat glands]] stop [[secrete|secreting]] [[sweat]] and the [[skin]] becomes dry.
*[[Erector Muscle|Erector muscles]] contract causing body hairs to stand on end. This creates a pocket of trapped air under the hairs which insulates the body.
*[[Blood Vessel|Blood vessels]] near the surface of the [[skin]] [[constrict]] reducing [[blood]] flow close to the [[skin]] preventing [[Thermal Energy Store|thermal energy]] being lost to the [[skin]].
*[[Muscle]]s throughout the body begin to shake. This is called shivering.
