长期生活于极寒冷地区的居民,由于寒冷的刺激可以产生一定的对外环境的适应能力。不少学者通过冬季行军锻炼,冬季体育锻炼,局部冷水锻炼和控制条件下的冷室锻炼等方法进行了提高人体耐寒能力的研究,并取得了一定的效果。但也有学者认为暴寒时间过短,不大可能产生完善的冷适应;冷水洗脸、手、足等局部锻炼,对部队一是难以坚持、二是短期内尚难肯定效果。目前,寒区部队进入冬季后大部分时间停留于室内,室外活动时间一般为4小时左右,由于接受寒冷刺激少,人体的抗寒能力一般停留于季节性适应的 Long-term residents living in extremely cold areas, due to the cold stimulation can have some adaptability to the external environment. Many scholars through the winter march exercise, winter sports, local cold water exercise and cold conditions under the control of the room to improve the body’s ability to improve the research, and achieved some results. However, some scholars think that the outbreak of cold is too short, it is unlikely to produce a complete cold adaptation; cold water, hands, feet and other local exercises are difficult to persuade the army one, and second, it is difficult to confirm the effect in the short term. Currently, cold-tempered troops stay indoors for most of the winter after entering the winter, and outdoor activities usually take about 4 hours. Due to less cold stimulation, the cold-resistant ability of the body generally stays in seasonally adjusted
