At the beginning of the New Year, with the heavy snowfall and plummeting temperatures, there has been a significant increase in the number of patients coming to the hospital for frostbite. Frostbite is a limited blood circulation disorder and inflammation of the skin caused by cold irritation. Many people think that frostbite only occurs when the temperature is below zero degrees Celsius, but in fact, it can be caused when the temperature is below 10 degrees Celsius, and of course, the lower the temperature, the higher the chance of frostbite occurring and the faster the time. Frostbite is especially likely to occur in people who lack exercise, have poor peripheral blood circulation, are anemic, have poor nutrition, and have sweaty hands and feet. Frostbite can also occur in people who do not pay attention to warmth when riding a bike, children who do not pay attention to insulation during outdoor activities, and women who wear thin, tight pants or skirts.
Performance of frostbite
1. Most often seen in children, women, the elderly and outdoor workers.
2. Frostbite occurs on the toes, ankles, fingers, backs of hands, ears, face and other exposed parts of the body. The outer thighs and buttocks of those who have worn thin tight pants or skirts are also good sites.
3.The lesions are characterized by limited bright red or dark red edematous erythema and plaques. For those who have been exposed to frost for a long time or repeatedly have frostbite, chaps, blisters, erosions and ulcers are likely to appear on top of the erythema, leaving pigmentation or scars afterwards.
4. There is obvious itching or itching pain, which is aggravated by heat.
Prevention of frostbite
1.Strengthen exercise and promote blood circulation.
2.Pay attention to nutrition and improve the ability to resist cold.
3. Pay attention to heat preservation, and do not wear thin or tight clothing and footwear.
Treatment of frostbite
There are many ways to treat frostbite, and here are a few small, easy-to-use methods.

But do not start with higher temperature water soaking, nor should you immediately bake on the stove.
