Frostbite is a skin disease caused by local skin inflammation due to cold weather. Therefore, it is crucial to prevent frostbite by avoiding prolonged exposure to cold, low-temperature environments. If it is necessary to be in such environments, it is essential to keep both the local areas and the entire body warm. You can wear hats, earmuffs, and gloves, and put on thicker shoes and socks. However, shoes, socks, and gloves should not be too tight, as overly tight clothing can also lead to frostbite.
