每个人睡眠的时间都有所不同,有的人甚至声称自己几乎不睡觉。那么,人类能否不睡觉也能活着呢?科学家们对此进行了一项剥夺睡眠的实验。在第一个不眠之夜,几乎没有引起任何问题。到了第二个晚上,嗜唾现象就变得极其厉害,大脑的功能下降,无法从事脑力劳动。这表明,大脑比身体更需要通过睡眠来休息,失眠时几乎看不到躯体有任何不适,但大脑却感觉到了。第三个晚上,实验者靠自己的力量保持清醒已经不可能,如果要继续保持清醒的话,则会不可避免地出现几秒钟的短暂睡眠。由于心理疲劳的加重,人开始变得容易冲动,出现神经官能症的症状,比如狂躁和幻觉,实验者已不再能进行自我的心理调控。此外,动物实验表明,当动物被连续几个星期剥夺睡眠后,它们的体温会迅速下降,最后导致死亡。 Everyone’s sleep time is different, some people even claim that they hardly sleep. So, can humans live without sleep? Scientists carried out a sleep deprivation experiment. On the first sleepless night, there was hardly any problem. By the second night, the phenomenon of addicted saliva became extremely severe, the functioning of the brain was diminished and mental work was impossible. This shows that the brain needs rest more than the body through sleep, insomnia can hardly see any body discomfort, but the brain felt. On the third night, it is impossible for the experimenter to be awake by his own strength. If it is to remain awake, then a few seconds of short-term sleep will inevitably occur. Due to the aggravation of mental fatigue, one becomes more easily impulsive and develops the symptoms of neurosis, such as manic and hallucinations, and the experimenter no longer has the ability to regulate himself. In addition, animal experiments show that when animals are deprived of sleep for several weeks, their body temperature drops rapidly and eventually leads to death.
