Is it possible to live without sleep?

Being able to sleep approximately eight hours a day plays an important role in the body, not doing so will lead to a series of health effects.

The dream in which we spend part of our life, why is it so necessary? The schedule of sleep and wakefulness is one of the elements that governs the sun, being able to see altered by the electric light, which allows us sometimes to late until the end of the television program, and even sleep with the television set, or to get up before it leaves S OL to take advantage to move to our job before the rest do and avoid traffic. Both late and early rise are alterations of the natural cycle of sleep, but when we think of the sun, and in the hours of light, it must be taken into account, that these not only change from summer to winter, but it also does according to the place of the world where we are , so at the poles in summer you can get to have days of nineteen hours of light and in winter the opposite, that is to say scarce of three to five hours of light. So, what is the best time to sleep?, this should be given by the place where he lives, adjusting as much as possible to the natural cycle of light-dark, so that they can receive the benefits of the first rays of the day, as they did in the old Egyptian culture. And the same should be done to sleep, ie when the sun goes, lie down, and with it naturally we would be regulated between the eight hours of sleep that usually requires the person to rest and replenish, also takes advantage of the organism to archive the Traces of memory on the experiences learned during the day, among others. But this sleep-wake cycle that we find so stable is varying slightly over time and once stabilized lasts a lifetime. In the first days of life, and still within the process of internal maturation, the baby sleeps between 16 and 20 hours a day. Being their sleep interruptions becoming more and more spaced as the months go by. It will gradually decrease until it approaches the eight hours when it will stabilize for a good part of our life, but with the aging there is a slight shortening, reducing in an hour or an hour and a half, and that even though it increases the Total time you are in bed. The Cronodisrupción is the technical term used to call the alterations provoked in the natural cycles of the person, as in the case of the jet-lag that is experimental when moving to another locality that is governed by a different day-night cycle, or as in the Deprivation of sleep shortening by both late and excessively early, which will provoke alterations both in the short and long term, being responsible for a higher incidence of metabolic syndrome, cardiovascular disease, Cognitive impairment, affective disorders and even premature ageing. The lack of sleep, i.e. sleeping less than the organism needs, to the lengthening will go to the detriment of the health of the person.
There have been experiments of deprivation of sleep, and it has been observed, that the not sleeping sufficiently, prevents to make new learnings, since the memory footprint is not recorded; Similarly, the immune system, which defends us against infections and attacks from outside, significantly lowers its performance; It produces a hypersensitivity to the light and the stimuli of the outside, being more irritable to any external fact. And that alone with thirty six hours of experimentation without sleep. Beyond this temporal limit, it has not been considered ethical to continue with the studies, for the irreversible damages that could be produced in the patient. Hence the importance of sleeping and doing it in an environment, ventilated and without noise, because despite being asleep our organism maintains a safeguard mechanism, by which, if there is some kind of noise we wake up as a safety measure, so that We can run or defend ourselves; A very useful mechanism, for our ancestors when they lived in the caverns, when faced with the threat of some scavenger, which gave them a few seconds to react. As we are now, if there is a loud noise, we quickly wake up, interrupting the cycle of sleep, and making it harder for us to go back to sleep.
