在寒冷的季节和寒冷的地方,户外工作时间长久,就常会发生人体冻伤的现象。尤其如果当时冷、湿、风三个东西同时夹攻的时候就更严重。根据研究,冻伤基本上可以分三种,第一种是单纯由于寒冷所引起的;第二种是单纯由于潮湿所引起的;第三种是由于潮湿和寒冷两者共同的作用所引起的。冻伤是怎样产生的呢?原来细胞在不同的环境温度下,能够生存的日期是不同的,按照实验结果,在比较低的温度下(例如-5℃)能够生存的日期较长(约15天),在比较高的温度下(例如30℃)能够生存的日期也较长(约20天),除了过份高的温度(例如60℃)能使细胞中蛋白质凝固不能生存外,一般环境温度在10℃到25℃之间,细胞生存的日期最短,尤其当温度在15℃左右时,能够生存的日期更短,不到5天,就要死亡。
In the cold season and in cold places, when people work outdoors for a long time, they often suffer from frostbite. Especially if the cold, wet, and wind are caught at the same time, it is even more serious. According to the study, frostbite can be basically divided into three types, the first is caused simply by the cold; the second is caused solely by the damp; the third is caused by the common effects of both moisture and cold. How is frostbite produced? The original cells have different dates of survival at different ambient temperatures. According to the experimental results, it is possible to survive at relatively low temperatures (eg -5°C) for a longer period of time (about 15 days). ), The longer the survival time is (about 20 days), the higher the temperature (for example, 30 °C), in addition to excessively high temperature (for example, 60 °C) can make the protein in the cell coagulation can not survive, the general ambient temperature Between 10°C and 25°C, the date of cell survival is the shortest, especially when the temperature is around 15°C, the survival date is shorter, and less than 5 days, it will die.
