Frostbite can severely damage skin, because ice crystals form within the tissue and deaden it. If not treated properly and immediately, the person might lose their sense of feeling.
If you know you are going to be outside in the cold, take precautions by wearing insulated gloves. Make sure to come inside every so often to warm up and keep your hands dry.
Step2
Immediately retreat to a warm environment upon recognition of frostbite.
Step3
Fill a bowl with lukewarm water and place the frostbitten area in the water. The water should not be hot.
Step4
Refill the bowl of water when it cools. Try to keep it at the same temperature each time. It could take a few hours to thaw the frostbitten skin.
Step5
Seek medical attention immediately even if you have successfully thawed the skin.
