When exposed to very cold temperatures, skin and underlying tissues may freeze, resulting in frostbite. The areas most likely to be affected are your hands, feet, nose and ears.
You can identify frostbite by the hard, pale and cold quality of the skin that has been exposed to the cold. As the area thaws, the flesh becomes red and painful.
If your fingers, ears or other areas are frostbitten:
1.Get out of the cold.
2.Warm your hands by tucking them into your armpits. If your nose, ears or face is frostbitten, warm the area by covering it with dry, gloved hands.
3.Don’t rub the affected area, especially with snow.
4.Get emergency medical help if numbness remains during warming. If you can’t get help immediately, warm severely frostbitten hands or feet in warm — not hot — water. The water temperature should be between 100°F to 105°F.
