1. What is Frostbite?
It’s no joke when Jack Frost is nipping at your fingers, nose, ears, and toes so severely that it causes frost bite.
Frostbite occurs when skin tissues, typically the extremities, are exposed to cold temperatures over long periods and literally freeze. Frost bite occurs in super cold conditions when the body constricts blood vessels to the arms and legs in order to send more blood towards the vital organs in order to keep you alive.
If your skin looks white or grayish-yellow, is very cold and has a hard or waxy feel, you may have frostbite. Your skin may also itch, burn or feel numb. Severe or deep frostbite can cause blistering and hardening. As the area thaws, the flesh becomes red and painful.
