Frostbite

Frostbite occurs when a part of the body becomes so cold that blood flow to the area is restricted. It most commonly affects exposed areas such as the hands, feet, ears, nose, and cheeks.

The first symptom of frostbite is typically that the skin turns pale or white and feels cold to the touch. Sensation in the affected area gradually disappears. When the skin begins to warm up again, you may experience stinging or burning pain. The area can become red and swollen, and blisters may develop as it thaws.

Warm slowly – skin to skin

Frostbite should be treated immediately, as delayed warming can lead to severe tissue damage. Rewarm the frozen area gently using body heat—place a warm hand against a frozen cheek or tuck frostbitten fingers under your armpits. To rewarm toes, use another person’s body heat, such as placing the feet against their stomach or under their armpits. Continue warming until normal color and sensation return, even if it causes discomfort.
