Frostbite! What should I do?

What is frostbite? Which department should I go to for frostbite?

Have you heard? The entire central and eastern regions will experience continuous rain, snow and freezing weather. I heard that this rain and snow weather will last the longest and affect the widest area!

Although the cold wave is fierce, it can't stop people. After all, the Spring Festival travel rush is about to begin, and we will always go out for activities. In this kind of weather, frostbite is an inevitable problem. So, what is frostbite? What department should you go to if you encounter frostbite? And how to prevent frostbite? Let's talk about this topic today.

First of all, we need to understand that frostbite is a local or systemic injury caused by the cold and damp external environment. Usually, the most common frostbite we see is local frostbite, which mainly occurs in the extremities, face, and auricle. Although it is not common to freeze to death directly now, local frostbite still occurs from time to time.

If the human body is exposed to cold for a long time, it will cause systemic hypothermia. When the core temperature of the human body is lower than 34℃, freezing will occur, and all parts of the body will be affected, including the heartbeat and breathing will stop. However, through effective preventive measures, we can still effectively avoid frostbite.

With the arrival of cold winter, people often get frostbite due to carelessness when doing outdoor activities or working. The location of frostbite is also relatively consistent, mainly occurring in the extremities with poor blood circulation, such as fingers, toes, ears and other parts. According to them, the severity of frostbite can be divided into four degrees. First-degree frostbite is what we often call "frostbite", which is only frostbite on the surface, with redness, swelling and congestion of the skin, feeling hot, itchy, and burning, and will heal itself within a few days. Second-degree frostbite will damage the superficial dermis, the skin will become red and swollen, and blisters of varying sizes may appear. There may be blood in the blisters, and there will also be edema and severe pain, and the skin will feel dull. Third-degree frostbite occurs under the skin, and the skin will turn black-brown or purple-brown. This type of frostbite is not easy to heal and will cause long-term allergies and pain. Fourth-degree frostbite is more serious and may damage muscles and bones, and even cause necrosis of limbs. In severe cases, it may even cause systemic frostbite, leading to cardiac arrest and sudden death.

So, what should we do if we encounter frostbite in our daily lives? First, we should immediately leave the cold environment and wrap the frostbitten part with warm and dry clothes. If the frostbite is serious, you need to see a doctor as soon as possible and never treat it yourself.

So, how to prevent frostbite? In this cold winter, preventing frostbite is related to our knowledge of cold-proofing, using appropriate warm clothing and equipment, etc. Although clinical treatment technology continues to advance, prevention is still the key.

First of all, when we go out or have outdoor activities, we should take protective measures in advance, add clothes in time, protect the parts that are susceptible to cold, and change wet gloves and shoes and socks in time. Never touch cold metal objects with bare hands. When choosing clothes, we should choose warm, waterproof and breathable clothes, such as down jackets, waterproof gloves, windproof caps, etc. At the same time, we should also pay attention to keeping our hands and feet warm and not expose them to the cold environment.

In addition, in winter, it is also important to eat more foods that can prevent cold. For example, black foods, such as black rice, black beans, black sesame, black fungus, etc., can replenish blood and promote blood circulation. Spicy foods such as ginger and pepper also have the effect of keeping out the cold. Beef, mutton, etc. are also good choices for keeping out the cold. In addition, eating more hot meals and drinking hot drinks can also enhance the resistance to cold and immunity.

In addition, we should also strengthen exercise to promote blood circulation. Moderate exercise can increase our body temperature, enhance our ability to resist cold, and reduce the occurrence of frostbite. In winter, we can choose to do some indoor sports indoors, such as yoga, Tai Chi, etc.

At the same time, we would like to remind everyone that people who work in outdoor environments for a long time should remember not to stay still for a long time. In addition to taking good warm-keeping measures, they should also strengthen exercise and walk regularly to promote blood circulation. If you feel unwell during work, you should stop working immediately and rest in a warm place indoors.

In short, in this cold winter, I hope everyone can stay away from the trouble of frostbite. Remember, keeping warm is important, but health is more important! Protecting yourself from freezing is not only about your body, but also about our beautiful and healthy future!

In addition, attention should be paid to coordination with the surrounding environment. For example, public places should be equipped with enough heaters and drinking water equipment so that people in need can use them at any time. At the same time, publicity and education should be strengthened to remind everyone to pay attention to warm-keeping measures and safety matters when going out in winter to avoid accidents caused by the cold.

Finally, let us once again emphasize the importance of preventing frostbite. Only through effective preventive measures can we stay healthy and warm in this cold winter.

Salute to the PLA soldiers who guard the stability of the motherland in the ice and snow!
