How is chilblain caused?

How is frostbite caused? Many people are afraid of the cold, especially in the south. At least the north has heating, and the south relies on its own willpower to resist cold. The weather in winter is so dry that many people will get frostbite if they don't pay attention to their hands. Here I'll tell you how frostbite is caused.

How is chilblain caused? 1 climatic reasons

In cold and humid areas, the incidence of chilblain is higher, for example, in rainy and cold Britain, the annual incidence rate is 10%. Although the winter temperature in the south of China is obviously higher than that in the north, the incidence of chilblain is close to that in the north, because the temperature in the north is low but dry, with indoor heating, while the winter in the south is wet and cold, with more rain, snow and frost.

Susceptibility problem

Even living in the same environment, everyone's situation is different, which shows that genetic susceptibility also has a certain impact on chilblain. Studies have shown that most people who are prone to frostbite have poor peripheral blood circulation or sweaty hands and feet, and are prone to microcirculatory disorders after catching cold.

Occupation is also one of the factors that affect the incidence of chilblain. In the cold season, people who need to work outdoors or have more contact with cold water, such as sanitation workers, catering workers and housewives, have a higher incidence rate than the general population. Especially in the middle and lower reaches of the Yangtze River, many waiters in hotels and restaurants are wet and cold because of contact with washing work in winter, and most of them have swollen hands when they see a doctor in the outpatient clinic.

Direct inducement

The direct cause of chilblain is cold, but anemia, endocrine disorders, chronic myelomonocytic leukemia, macroglobulinemia, cryoglobulinemia, antiphospholipid antibody syndrome, Raynaud's disease, anorexia nervosa and so on. Can induce chilblain.

How is chilblain caused? 2 1. The occurrence of chilblain is closely related to age.

According to research, children and adolescents are very prone to frostbite, and the probability of young adults is relatively low, and the elderly are the least prone to frostbite. This is because the contraction response of subcutaneous small vessels in children and adolescents is much stronger than that in middle-aged people, especially in the elderly. Under the stimulation of cold, the subcutaneous blood vessels of children and adolescents have spasmodic contraction and congestion, and local tissues are malnourished and easy to be injured, while the subcutaneous small blood vessels of the elderly are not sensitive to cold stimulation, so frostbite is not easy to occur.

2. Gender also has a certain influence on chilblain.

At the same time, the incidence of chilblain is also affected by gender. Young and mature women are more prone to chilblain than men of the same age, because women's skin has lower resistance to cold.

Physical strength and blood circulation are also closely related to frostbite. People with heart disease, vascular disease and poor peripheral blood circulation have poor adaptability, tolerance and resistance to cold and are prone to chilblain.

3. Lack of activity and cold.

Standing for a long time, lack of activity, narrow clothes, malnutrition and excessive fatigue are also easy to get frostbite.

Humidity is another cause of frostbite.

People who live and work in humid environment can obviously aggravate the influence and harm of cold on them, and it is easier to destroy the contraction and relaxation function of local blood vessels and promote the formation of chilblain. Therefore, frostbite is more likely to occur in a humid environment than in a dry environment.

How is chilblain caused? 3 1. The climate is cold.

Because the climate is cold, there will be a smooth blood flow in the local skin of the human body. If you don't pay attention to keep warm, it will easily lead to frostbite.

2. Age factor

Generally speaking, children and adolescents are most prone to chilblain, followed by young adults and finally the elderly. This is because the skin of teenagers and children is fragile. Once stimulated by cold, it is easy to cause the small blood vessels under the skin to contract sharply, and then there will be blood stasis. So the younger the person, the easier it is to get frostbite.

Step 3: physical strength

If a person's physique is weak, coupled with poor blood circulation, it is easy to grow frostbite in cold seasons. In addition, if an individual's skin has poor adaptability to cold stimulation, or can't stand the stimulation of cold air, it is easy to cause chilblain, which has a lot to do with personal physique.

4. Lack of exercise

People who often don't exercise are also prone to frostbite. This is because the lack of physical exercise is very easy to have poor blood circulation and the body's cold resistance is weak. Once stimulated by cold, it is easy to cause frostbite.

5, do not pay attention to keep warm

If you don't keep warm in the cold season, it is easy to cause frostbite. Frostbite generally occurs in ears and limbs, so it is necessary to strengthen the warmth of ears and limbs in winter to prevent frostbite caused by poor local blood flow.
