2. For treatment, we must first get rid of the cold environment, take off the wet clothes and gradually regain the temperature in warm water. For severe frostbite of the whole body, artificial respiration can be performed when necessary to enhance heart function, resist shock and replenish water. In addition to rewarming massage, chilblain can also be rubbed with alcohol and pepper water, which has a good effect, or rubbed with 5% camphor alcohol and various chilblain cream, which also has a certain effect. If there are blisters on the second degree chilblain, you can puncture with a sterile needle to extract the liquid, and then apply chilblain cream. Third-degree and fourth-degree frostbite should be treated with warmth.

chilblain
As we all know, chilblain is caused by cold stimulation on the exposed parts of human body. In people's imagination, the peak of frostbite should appear in the cold period of winter, but this is not the case. Experts pointed out that hand and foot frostbite, especially foot frostbite, mostly occurs in late autumn and early winter when the weather is not too cold. So this time is called the first frostbite peak in the whole year, and the best anti-freezing time is late autumn and early winter.
Countermeasures:
The specific method to prevent frostbite is to soak the parts where frostbite often occurs in previous years, such as hands and feet, with cold water from late autumn to early winter. Soak for half an hour every day, soak for another hour, and then pay attention to local warmth. For example, when going out in cold weather, use masks, gloves, windbreak earmuffs and scarves early. Shoes should also be warm, but not too tight. In addition, you can eat some beef and mutton isothermal supplements to enhance your body's cold tolerance. If it is a person diagnosed as yang deficiency and internal cold by traditional Chinese medicine, Chinese patent medicines such as Liuwei Dihuang Pill can be taken orally as soon as possible as a precaution.
Health reminder
Disease prevention: chilblain and dermatosis.
Diet regulation: Winter is the best period for tonic and health preservation, and drinking more soup is a good way to enhance physical fitness. Chicken soup, bone soup, fish soup and vegetable soup can enhance human resistance and purify blood.
Fitness exercise: strengthen exercise, do chest expansion exercise and breathing aerobics.
The injury caused by low temperature and cold invasion is called frostbite. Frostbite can be local or systemic (frozen stiff), which is mostly caused by cold, humidity and tight clothes and shoelaces, and mostly occurs in skin, hands, feet, fingers, toes, ears, nose and other parts. Frostbite is divided into four degrees. At one time, frostbite was the lightest, that is, the common "frostbite", which was damaged in the epidermis. The frozen skin was red, swollen and congested, and the symptoms disappeared after a few days. After healing, there is no scar except epidermis shedding. Second-degree frostbite damaged epidermis and dermis. After the injury, besides redness and swelling, it is accompanied by blisters, which can be bloody liquid, and edema, severe pain and skin insensitivity can occur in the deep part. Third-degree frostbite hurts the whole skin, showing black or purple-brown, and the pain disappears. It is not easy to heal after injury, except scar, which may cause long-term allergy or pain. Fourth-degree frostbite damages skin, subcutaneous tissue, muscles and even bones, which may lead to necrosis, loss of sensation and scar formation after healing.
In the process of treatment, we should first get rid of the cold environment, take off the wet clothes and gradually heat up in warm water. If necessary, artificial respiration is feasible for severe frostbite all over the body to enhance heart function, resist shock and replenish water. In addition to rewarming massage, chilblain can also be rubbed with alcohol and pepper water, which has a good effect, or rubbed with 5% camphor alcohol and various chilblain cream, which also has a certain effect. If there are blisters on the second degree chilblain, you can puncture with a sterile needle to extract the liquid, and then apply chilblain cream. Third-degree and fourth-degree frostbite should be treated with warmth.
Prevention of frostbite is mainly to keep warm and enhance cold resistance.
In winter, many people's hands, feet and ears are easy to freeze, which leads to chilblain pain and itching, and some even fester and infect. In addition to the cold weather, there is another important factor closely related to blood circulation. In winter, people's activity is less, blood circulation and metabolism slow down, especially on the back of hands, ears and feet, which is easy to cause local tissue necrosis and chilblain. In order to prevent frostbite, besides keeping warm, the best way is to rub and massage your hands, feet and ears frequently, and insist on washing your face with cold water or proper sports activities to speed up blood flow.
In the early stage of chilblain, two fresh peppers, two fresh eggplant roots, three fresh orange peels, eight slices of ginger and fifteen roses can be used. Stir-fry peppers, eggplant and ginger for fifteen minutes, then add roses and orange peel for eight minutes, and soak the juice on your hands and feet once a day. If it has festered, it can only be used after the wound has healed.
Prevention and treatment of chilblain
Frostbite is the most common skin disease in winter, which mainly occurs in exposed parts of the body and limbs far away from the heart, such as ears, nose, hands and feet.
① Physical exercise: This is the best way to prevent frostbite, and improve the body's adaptability to cold through physical exercise.
2 preparation method for keeping out the cold: when working outdoors in winter, be sure to eat and wear warm clothes and make all kinds of preparations for keeping out the cold. For example, wear gloves, hats and cotton shoes. Keep the inside of clothes dry. Always rub some oil on ears, face, hands, feet and other parts that are easy to freeze to protect the skin.
3 cold and warm water method: In order to prevent frostbite, you can usually rub the easy-to-freeze parts with cold water until they are red, and wash the easy-to-freeze parts with warm water every night before going to bed. Can increase the cold resistance of these parts.
④ Single-headed garlic method: This method can be used for parts prone to frostbite every year before the arrival of winter. Take a garlic with one end, mash it, heat it in the sun, gently rub it on the frostbite-prone part until small bubbles appear locally, and then pick out the bubbles with a disinfection needle. This method can make local qi and blood unblocked, thus reducing the occurrence of chilblain.
⑤ Raw radish method; Cut the radish or green radish into large pieces (slices), put them on the fire, then gently rub the frostbite-prone parts, cool them and bake them again until the radish is completely hydrated. This method can prevent frostbite and treat frostbite.
⑥ Ginger (slice) method: Gently rub chilblain with a slice of ginger until it has fever, or use a slice of fresh ginger, simmer it by the stove, cut it into slices, and rub the affected area. Or mash 50 grams of ginger, soak it in Chinese liquor once or twice, mix well and apply it to the affected area three times a day.
⑦ Vinegar therapy: Take a proper amount of vinegar and heat it on the fire, then cancel the poisonous gauze and apply it to the affected area with vinegar.
