Prolonged exposure to coldtemperatures can have a profoundeffect on the skin.When tissues are exposed toabove-freezing temperatures,localized vasoconstriction and increasedblood viscosity reduce bloodflow and decrease the amount ofoxygen available to tissues. Whentissues are exposed to freezing temperatures,water within those tissueschanges into ice crystals; this resultsin either intracellular or extracellulardamage and tissue necrosis.
