随着环境湿度的变化,鱼类、青蛙和蛇的体温都会有所变化,但人的体温却“不为所动”,因为人是恒温动物。但你要是以为人的体温是绝对的“恒温”,那就大错特错了！人体所谓“恒温”,也是在一定的范围内波动,伴随人体冷暖的变化,会产生许多奥妙的生命现象。
As the humidity of the environment changes, the body temperature of fish, frogs and snakes will change, but the human body temperature will be “unmoved,” because humans are warm-blooded animals. But if you think people’s body temperature is absolutely “constant temperature”, then it is wrong! The so-called “constant temperature” of the human body also fluctuates within a certain range. With the change of body warm and cold, there will be many mysterious life phenomena.
