Why people need sleep?

Human need 1/3 time of their life to sleep. The reason that people must sleep is that cerebra need to relax and maintain some most important neuron group in deep sleep. There are 10 billions nerve cells in human cerebra which transfer messages to all the body corners, unused nerve cell will atrophy and even die. The animals experiment also proved that white rat will die one after another if they don’t sleep for several weeks, but their apparatus haven’t been found any obvious damage, just because they lack sleep serious lead to the immune function break down, and can’t resist the bacterial affect, and then it die. Also, some study & testing show that a person whose sleep less 4 hours will catch a disease more easier than those whose sleep time reach 7-8 hours, even die. And if a person who don’t sleep in 72 hours continuingly will be in deranged mentally.
According the EEG and other body’s change judged, a normal person when he sleep, first enter the NREMS, there are four stages: when people have just gone to sleep, he or she is easy to wake, and can listen the around voice, this is just the first stage; Then the secondly, it’s called Light Sleep (about 30-40 minutes), this stage is the longest, it’s composed 50% of the whole sleep time; The third and the fourth stage are the Deep-Sleep, during these two stages people sleep soundly, and have no consciousness. The NREMS pass about 70-90 minutes, will enter another different quality sleeping, there is a rapid circular movement of the eyes, it’s called REMS, from fall asleep to the REMS as the first cycle, and then from light sleep to the deep-sleep until the REMS are over as the second cycle, in this way, during the sleeping time people will go 4-5 alternations of sleep cycle, the best time to recover the organism is the second and the third cycle. The first REMS only keep 5-10 minutes, the last REMS (before you wake) can keep 30-40 minutes.
