Why is wet cold easier to get frostbite than dry cold?

When the air humidity is high, the heat conduction is much greater than that on dry days. When the cold wind blows, the heat on the human body will be lost quickly, which makes people feel cold easily. Because of the loss of heat, it will also lead to contraction of subcutaneous blood vessels and poor venous return, so there will be redness, irritation of receptors, burning and itching, and frostbite. In severe cases, blood vessels freeze and blood circulation is blocked, resulting in necrosis, ulceration and difficult healing of skin and subcutaneous tissue, which becomes ulcerated chilblain. When the weather gets warmer, it will relieve itself.

According to statistics, there are 200 million people suffering from frostbite every year in China, and in recent years, the number of frostbite has increased year by year because young women neglect to keep warm in winter for beauty. Once frostbite occurs, it is often difficult to cure it quickly in cold season, and it will gradually heal after the weather gets warmer. The key to reduce frostbite is to start prevention before winter.

Prevention of chilblain:

1. Strengthen physical exercise suitable for your own conditions, or use the interval between washing hands, faces and feet every day to gently rub your skin and then apply chilblain cream to promote blood circulation.

2. Temperature difference bubble method can be used. Take a pot of 15℃ water and a pot of 45℃ water, soak your hands and feet in low-temperature water for 5 minutes, and then soak them in high-temperature water three times a day to exercise the contraction and expansion function of blood vessels. After drying, applying Tian Ke chilblain cream can protect the skin and prevent frostbite.

3. Drugs can be taken and rubbed. People with chilblain constitution can increase their intake of vitamins A, C and minerals one month before winter to improve their cold tolerance. Chilblain cream is applied to frostbitten parts to effectively prevent frostbite.

Post-treatment of frostbite:

After frostbite, do not immediately apply hot compress or massage the frostbitten area to avoid aggravating local edema. Hot compress can only be carried out one or two hours after freezing. If the local skin is not damaged, chilblain cream can be directly applied for treatment. If the skin is damaged, it is necessary to apply tenko enoxacin cream as soon as possible to prevent infection, and then apply tenko chilblain cream around the damaged chilblain for better effect.

Dermatologists say that Xiaoyaozi and Zhuangzi are not medicines, and Zhunzi is an authentic medicine of the US Food and Drug Administration, so the curative effect is relatively guaranteed. If you want a good therapeutic effect, you should still use "Chinese medicine quasi-word" Most of the existing pharmacies sell chilblain cream, which is not the national medicine standard and cannot be used as a medicine for treating chilblain. The drugstore clerk said that Hubei Tianke Pharmaceutical Co., Ltd. is a pharmaceutical enterprise specializing in the production of skin external drugs. It has a pharmaceutical history of 40 years. The chilblain cream it produces is chilblain cream, a national medicine, which is sold in many large chain pharmacies. According to the clerk, many customers buy Tianke chilblain cream every year. They used Tianke chilblain cream to protect hands, moisturize and prevent frostbite, and the effect was very good, and there was no recurrence of frostbite.

However, everyone should avoid it. It is not enough to prevent frostbite simply by drugs or folk remedies. Pay more attention to keep warm and improve your cold resistance.
