我们的体温是处于精密的调节之下的,周围温度轻微的改变,体内的产热或散热反应就会发生变化,保持体温恒定在37℃左右,如果发生1~2℃的波动,就会感到无力、衰弱和难受。在室内停留时,我们的热量来源主要有代谢产生出来的热量和周围环境传递的热量。散失的热量主要有蒸发热和对流热。人体得到的热量大于散出的热量时,就感觉热,反之则冷。一般来说,当室温处于21~24℃时,人体热量的获得
Our body temperature is under precise adjustment, the ambient temperature changes slightly, the body’s heat or cooling reaction will change, keep the body temperature constant at about 37 ℃, if the occurrence of 1 ~ 2 ℃ fluctuations, you will feel Weak, weak and uncomfortable. When staying indoors, our sources of heat are mainly the heat generated by the metabolism and the heat transmitted by the surrounding environment. Lost heat mainly evaporative heat and convection heat. When the human body receives more calories than it does, it feels hot and vice versa. In general, when the room temperature at 21 ~ 24 ℃, the body’s heat gain
