This year January turned out to be really winter and cold. And all sorts of problems immediately began: the car does not start, you can only move along the street with short dashes. And several times he froze his hands so that the pain persisted throughout the day. He rubbed his hands with snow several times, since he had heard about this method since childhood, but he only tore the skin, and the pain became even stronger. What should you do if you got frostbite? Ilya Shkurin, Yekaterinburg Usually, frostbite is understood as tissue damage that appears under the influence of low temperature. Among the main symptoms are called pallor of the skin, loss of skin sensitivity, painful sensations. Open parts of the body most often suffer from frost - ears, nose, cheeks. Hands may also be injured if gloves are not worn, or feet if, for example, tight shoes are used. FROSTBITE is not such a rare problem for humans, and it can happen to anyone. Therefore, it is very important to know and understand how to act correctly in this case, since, as practice shows, many people are subject to harmful stereotypes and make mistakes that lead to serious complications. One of the most common is just the one that the author of the question told about - rubbing the damaged area with snow in order to disperse the blood. In fact, as experts say, this is not necessary. They are based on the fact that snow has a crystalline form, and when rubbed, acts on the skin as a kind of abrasive, damaging its surface layers. In addition, snow is also cold and can itself cause hypothermia (cooling). And, in all honesty, in large cities there is practically no pure snow. The second common myth is to smear the affected area with something greasy and nutritious. The fact is that, according to doctors, fat forms a film that clogs the pores and disrupts the natural thermoregulation of the skin - one of its main functions is the ability to warm and cool. The fatty film interferes with this process, and the superficial part of the skin does not work as it should. Finally, the third mistake is to try to warm up the frostbitten area with water. It all depends on the degree of frostbite. For example, if a person has been in the cold for a long time or got frostbite by going under water in clothes, then the frostbite process penetrates very deeply, and in this case even a cool liquid may turn out to be hot for the victim. And in such a situation, an option occurs, as with a burn. If you pour ice water over the burn, it will cause a spasm of the superficial vessels. Thus, blood flow to deeper tissues is disrupted and heat transfer is reduced, thereby leaving heat in the depths. In a situation with frostbite, cold remains in the depths. Using too hot water will lead to a situation where only superficial vessels will expand, and it is necessary to warm up from the inside and gradually. How to properly keep warm with frostbite? First you need to move from the cold to a warm room. If the victim is in wet clothes, then it is necessary to remove them. Next, you need to give a warm drink - plain water or weak tea is best suited. It is important that the drink is exactly warm, so that the patient can warm from the inside. You can also cover the victim with a warm blanket or blanket. In addition, experts advise to apply heating pads with warm water - not too hot, but heated to a temperature close to the temperature of the human body. Well, what you should definitely not do is try to warm yourself with alcohol. And even more so, you should not drink alcohol before going outside, when it is frosty there, since the pores and surface vessels expand. And this can be the reason that a person will really be hot for a while, he will sweat, unbutton, and then he can freeze even more, and there will be a risk of illness. And of course, frostbite should never be ignored. Especially if the above measures did not help. It is imperative to consult a medical professional to determine the degree of frostbite and hypothermia of the body. This will help in deciding whether further hospitalization is required, followed by monitoring of the patient's condition. And this point must be taken with full responsibility. After all, frostbite is fraught with serious complications. With severe hypothermia, vascular spasm occurs, blood supply is disrupted. Fingers and toes are most commonly affected. Peripheral circulation is impaired, there is a risk of necrosis of these zones, the development of necrosis. So you have to take care of yourself. Dear Readers!
