Frostbite happens when the skin and the tissue below freeze. It happens on the fingertips, toes, ears, nose, cheeks, and chin.  first, your fingers get cold and turn red, then they become numb, finally, they become hard and pale. The image people associate the most with frostbite is the dark, dead skin when the limbs freeze. Most cases of frostbite could be cured with gradual warming. Severe cases end with a limb or two amputated. In order to stop frostbite or to keep from getting it,  wear anything warm such as gloves, beanies, earmuffs, scarfs, etc.
