It takes about 40 minutes until the skin color turns dark red or purple. Frostbite of auricle or face can be soaked with warm water towel for local hot compress. In the absence of warm water, the frozen limbs can be placed in other people's chest, abdomen, armpit and other warm parts to rewarm. If the pain is severe during rewarming, analgesics can be given.
