This time of year when the cold continues. You may also use disposable warmers or electric blankets. At that time, I would like to be careful about the fact that it is cold. The word cold often gives the impression that it’s mild, but there are actually serious cases.
◇ ◇ ◇
What are the causes of “burns” and which parts of the body tend to get cold?
It’s cold, but it occurs when you keep in contact with a heat source that is slightly higher than your body temperature for a long time. The main cause is using items that keep your body warm, such as body warmers, hot water bottles, electric warmers, electric blankets, and hot carpets, in the same place for long periods of time.
Areas that are particularly susceptible to this are areas that are easily compressed, such as heels, ankles, shins, and buttocks, where bones are prominent and there is little fat.
Also, although it may come as a surprise, laptop computers can also be a cause of this problem. If you use a battery or the area around the exhaust vent may become slow, if you continue to work for a long time with the device on your lap, the same area, such as vegetables, will come into contact with the heat source and will continue to be compressed, making you more likely to develop the condition even though it is at a low temperature.
It’s normal, but the only difference is that the symptoms are progressing.
General burns (high-temperature burns) are damage to the surface of the skin caused by short-term contact with a high-temperature heat source. On the other hand, the big difference is that the relatively low temperature heat source is slowly transmitted to the skin and deep layers (from the dermal layer to the subcutaneous tissue).
Therefore, the damage may progress without any symptoms, and by the time the injury is noticed, it is rarely serious.
However, over time, blisters (water damage) may develop, and the skin may become whitish or darkened. At this point, it is considered a sign that the damage has already reached deeper layers of the skin.
Burns are classified into three grades, starting with degree I, depending on how deep the skin damage has reached.In most cases, low-temperature burns are classified into degree II or degree III, which are more serious at the stage of onset. In cases of “grade III”, natural recovery is difficult and surgery (skin grafting) is required in most cases.
It’s cold, but it’s not temporarily “light”.
