Sleep can be eliminated or the key to life. Nancy Cres's "Spanish Asses" tells the concept of the futuristes who do not need to sleep; it further addresses the idea of sleep and genetic change that leads to sleeping becoming an unnecessary routine. There is a clear social boundary between a person who can sleep and a person who is genetically modified so that sleep is no longer necessary. Indeed, sleep can be eliminated from everyone's daily life without adversely affecting the physiology and psychology of the body.
Sleep is the key to creating a healing environment for the body and mind. For example, sleep deprivation and response time are shortened, glycogen and carbohydrate intake (two important energy sources of the body), cortisol (the main stress hormone of the body) increase. All of these will have a negative impact on your thinking and behavior. The scientific reason behind it is that the blood vessels contract (tighten) at low temperatures and the vessels are dilated (expanded) at high temperatures. This alternating motion of the vessel mimics the body's "muscle pumping" effect - it reduces inflammation and eliminates waste of muscle metabolism
Lack of sleep has been underestimated for a long time as a necessity for survival, but the seriousness of sleep deprivation can have a negative impact on your health and life. Problems include hypothermia, cognitive dysfunction, and hallucinations. The mechanism of sleep is unknown, but the side effects of sleep deprivation are so. Headache begins 24 hours after sleep. After 72 hours, memory has been compromised, and the reality has been distorted. Driving at this time is very dangerous. After 96 hours of no sleep, cognitive impairment was severely compromised. After 144 hours, hallucinations begin, you can not concentrate on or do the work. Lack of clear thinking may endanger life
