Frostbite occurs because of prolonged exposure to below freezing temperatures or to above freezing temperatures if there is strong winds or if the person is at high altitude or wet. Because of prolonged exposure to cold condition the body tries to preserve heat. That results the constriction of blood vessels and forcing more blood into the core. It helps to keep a body’s temperature above the 93°F .To keep the extremities as warm as possible our blood vessels alternate between constricting and dilating, but below freezing temperature the vessels stop dilating .Then our skin temperature becomes low enough and some ice crystals are formed in our cells. This disease mainly affects the hands, feet, nose, cheeks and ears.
