Hello, especially in winter, the weather is cold. In our daily life, everyone will choose many warm artifacts, such as warm baby, hot water bottle, electric blanket and other "warm artifacts". Although it can make us warm up quickly, it is likely to cause skin burns if used improperly. Although these heating artifacts can't reach a certain high temperature, the skin burns caused by long-term contact with objects above body temperature, which is called "cryogenic burns".

Long-term exposure to moderate temperature (generally 44~50℃) is easy to cause progressive damage from superficial dermis to deep dermis and subcutaneous tissue. Although the pain of low-temperature burn is different from that of high-temperature burn, only the skin is red, swollen, blisters, peeling or whitening, and the area is small, but if we don't pay attention to it and treat it in time, it will easily lead to wound ulceration. If low-temperature burn is found, the heat source should be removed immediately, and the burned area should be washed with cold water for 30 minutes or partially iced. If there are blisters, avoid bursting if the blisters are not broken. Those with severe burns should go to the hospital in time after cold water washing. Toothpaste and soy sauce are not good medicines for treating scalds, which are easy to cause infection in scalds and increase the difficulty of treatment.

Therefore, when using the "heating artifact" in peacetime, we must develop good habits. Don't use the hot water bottle and warm the baby personally, and don't put it in the same place for a long time. When in use, wrap it with a towel or separate it with a blanket. Do not touch it directly. Take it out before bed. The use of electric blankets should be turned on before going to bed and turned off when sleeping. It is necessary to develop good habits so as not to cause injuries during use.
