One of the mechanisms that help the body to conserve its heat is the slowing down of the blood flow towards the parts of the body exposed to cold temperatures. Another is to shiver when it is cold to keep the warmth of the body through movement.
The mechanisms that are used to help the body conserve heat are vasoconstriction and shivering. Vasoconstriction occurs when the blood vessels constrict causing the blood pressure to rise. Shivering occurs when the body becomes cold and it helps to maintain homeostasis.
