Why do some people get frostbite in their ears and hands in winter?

Although many people wear gloves, earmuffs and cotton shoes in winter, they will still get frostbite, and some people will not get frostbite even without gloves and earmuffs. Why? Then let's look at Bian Xiao, why some people get frostbite on their ears and hands in winter.

First of all, frostbite is usually born in winter, but rarely in summer, because frostbite is most directly related to cold weather. Because of the cold winter, the skin of human hands and ears is tender compared with other parts. Once exposed to cold air for a long time, it will be attacked by cold air. Moreover, it is cold in winter and the blood circulation of human body decreases. Healthy people, such as construction workers and athletes, rarely get frostbite even if they are exposed to the cold wind for a long time. Mainly because they are active every day, the blood circulation is vigorous, the blood flow is unobstructed, and all bare parts of the body have enough heat to provide, so they are not easy to get frostbite. But some people are relatively weak and have anemia, heart disease or other problems. Even if it is well protected in winter, it is easy to get frostbite, because these people are weak, lack of exercise, poor blood circulation in winter, and even cause local tissue necrosis.

Moreover, scientific research shows that frostbite has a certain relationship with heredity. Living in the same environment, everyone's situation is different. Most people prone to frostbite have poor peripheral blood circulation and sweaty hands and feet. Compared with others, people whose parents are prone to sores are also prone to frostbite. And frostbite is also related to occupation. If you still need to work outdoors or touch cold water in winter, such as sanitation and catering workers, the incidence rate will be higher than that of the general population.

In short, there are many reasons for frostbite, both our own reasons and genetic factors. We should apply some drugs in time after frostbite. If it is serious, you need to go to the hospital for a physical examination, otherwise frostbite in winter is very painful.
