Many reasons of sleep is not yet study...
But essential is a protection of organism.

Traduire cette page18 août 2014 - See what modern science says about the evolution of sleep, why ... to sleep regulation and the biological functions that manage sleep and ...
Sleep is necessary for the body to function properly. However, the fact that sleep makes us feel better and that going without sleep makes us feel worse indicate and explain why sleep might be necessary . Sleep helps someone to regain strength and relaxation of the body system after undergoing tedious work and day activities. We feel more alert, more energetic, happier, and better able to function following a good night of sleep. Sleep makes some one to be conscious after a stressful day.
From a biological point of view, the question ‘What is the function of sleep?’ admits more than one type of answer. One of them would be the functional response, involving the physiology of sleep (as the process is triggered?, what happens during sleep? and so on). But maybe we don’t need to know the functional response to be convinced that sleep should not be a vestigial feature. I’d mention two (a priori) reasons to think so. Firstly, we spend almost a third of our lives sleeping, and it is hard to imagine that a portion so expressive of our lives is occupied by something ‘vestigial’ (at least in the sense that we give to this word when we think in certain structures of our bodies, like the coccyx). Secondly, I suspect that the duration of sleep varies greatly between the different species of mammals, and I think this fact is connected (among other things) with the corresponding variation that these animals experience in the brain size.
Update (July 23). An extensive article about sleep (‘While we sleep, our mind goes on an amazing journey’, by M Finkel; to appear in August issue of the NG magazine) was published (today?) and can be read here: https://www.nationalgeographic.com/magazine/2018/08/science-of-sleep/.
Awesome ! Thanks for sharing the article. Will get back after reading it. May be!
