A popular method of treating frozen fingers and toes in very cold, even freezing weather is to slowly rewarm them or rub them with snow. The best treatment, however, is not slow rewarming but rapid rewarming. Putting the frozen fingers or toes in a warm bath or using a hot water bottle are both good ways to treat them. Hot drinks to warm the body from within are also helpful. One must be careful about burning the skin, however. The temperature of any heat applied should not be greater than 43 C.
