First aid - Frostbite

When exposed to very cold temperatures, skin and underlying tissues may freeze, resulting in frostbite. The areas most likely to be affected by frostbite are your hands, feet, nose and ears.

You can identify frostbite by the hard, pale and cold quality of 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 suffer frostbite:

• Get out of the cold.
• Warm your hands by tucking them under your arms. If your nose, ears or face is frostbitten, warm the area by covering it with dry, gloved hands.
• Don't rub the affected area. Never rub snow on frostbitten skin.
• If there's any chance of refreezing, don't thaw out the affected areas. If they're already thawed out, wrap them up so they don't refreeze.
• 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. You can warm other frostbitten areas, such as your nose, cheeks or ears, by covering them with your warm hands or by applying warm cloths.
