答案是否定的。低体温活动与低温下的活动是两个不同的概念。低体温活动是指人体温度低于37℃时进行的活动,人体在此条件下是不能冬泳的。人体体温只有身体在寒地冻僵或海中落水,处在死亡威胁时才会降到37℃以下。因此,人在冬泳时,不论水温、气温多低,内脏体温都会保持在37℃左右的温度线上。那么,冬泳时的低温究竟到了何种程度?它与人体37℃的恒定体温相差多少?现举4个不同城市为例(见表1)。 the answer is negative. Hypothermia activity and activity at low temperatures are two different concepts. Hypothermia activity refers to the human body temperature is below 37 ℃ when the activity, the human body in this condition is not winter swimming. Body temperature is only the body in the freezing cold or sea water, in the threat of death will fall below 37 ℃. Therefore, people in the winter swimming, regardless of water temperature, low temperature, visceral body temperature will be maintained at about 37 ℃ temperature line. So, what is the low temperature in winter swimming? What is the difference between it and the constant body temperature of 37 ℃? Take four different cities for example (see Table 1).
