Frostbite happens mostly in your hands, feet, nose, and ears. It happens when skin is bare or gets wet in sub-freezing temperatures. The low temperatures cause ice crystals to form in your skin.

Here are a few things to help you spot frostbite before it gets too serious:

* It hurts in small areas

* You get numb in the same spots that it hurts

* You feel tingling in those same spots

* Your skin gets hard and white

* Your skin starts to peel or get blisters

* Those parts start to itch

* Your skin gets firm, shiny, and grayish-yellow

If you think you have frostbite you should go to a sheltered place and take the wet clothes off the places that have frostbite. You shouldn't rub the spots that are frostbitten or it will damage your skin. Put your frostbitten skin into water that is around 100 degrees Fahrenheit. Use a thermometer to check the water's temperature, because if the water is hotter than 100 degrees it can make your frostbite worse. If you don't have warm water wrap the frostbitten body parts in warm blankets, coats or other materials. If you don't have enough blankets or other things to wrap yourself in, put your frostbitten parts on a warmer body part. If you have frostbite on your feet, don't walk. If your frostbite is serious get to a hospital as soon as possible.
