The specific way to prevent frostbite is to start in late fall and early winter by soaking parts of the body that have often had frostbite in previous years, such as hands and feet, in cold water. Soak for half an hour every day at first, and for an hour later. Next, pay attention to local warmth, such as using masks, gloves, windproof ear muffs, scarves, etc. early when going out in the cold. Shoes should be worn warm, but not too tight, to avoid local pressure. In addition, now you can eat some beef, mutton, drink ginger tea and other warm food to enhance the body’s ability to withstand the cold. You can also go play ball, run, climb mountains to enhance physical fitness and promote blood circulation. Many people know that they are prone to frostbite, but they don’t pay attention to prevention. When frostbite sets in, they remember to keep warm and cold or go to the hospital for treatment, but by then they have already missed the best time to treat it. If you have frostbite, you need to treat it in a timely manner. The physical therapy department of Hangzhou Red Cross Hospital has a wax therapy machine that can prevent frostbite, especially for those who have recurring attacks, and people with recurring frostbite can try it.
