Frostbite and Pernio
Cold temperatures and wind can lead to frost bite, which is similar to a burn. Frost bite can be superficial or deep. You can prevent frost bite by wearing a face protector. Types of face protectors include neck gators and nose protectors. Applying a heavy coating of Vaseline to the cheeks and nose can help protect delicate skin. Hand and boot warmers and boot gloves are also beneficial.
Early signs of frostbite include whiteness of the skin, stinging or numbness. If you or any person you know is experiencing these symptoms, rapid and moist re-warming in a tub or steam room is the best method for preventing permanent damage. If the skin is injured, do not go back outside on the same day.
Over-the-counter cortisone or a prescription cream can effectively treat frostbite. Keeping the injured area moist using Vaseline can speed healing.
Pernio, or chilblains, is a condition characterized by purple, painful, itchy bumps on the fingers, toes, ears and nose due to exposure to cold and wet conditions. Keeping your face, hands, and feet warm and dry can prevent this condition.
