It does this by widening (opening or broadening) veins (blood vessels) to discharge heat, or by “choking” veins to hold heat. Another method is by emitting sweat which then evaporates on the skin’s surface so as to initiate a cooling system. Also, the hypodermis layer of the skin gives protection in addition to maintaining heat. The hypodermis is the layer under the dermis and is mostly made up of fat.
