Despite extensive daily duties, always missing a few hours a day, mostly reimbursed by sleep. But the question is how long we can stay awake and the consequences of it?
Nouveau parents think that nobody sleeps as little as them. Major competitors certainly are students when making compensation between learning, publishing and sleep, the last (non) action usually "eats". But the longest period that a person had undergone without sleep is 11 days.
Randy Gardner, 17-year-old high school student from California decided to spend awake 264 hours without interruption. May be decided more, but so served. The remains had numerous consequences of memory loss, paranoia and hallucinations.
Were later made other studies examining the lack of sleep in mice, and the consequences that were similar to Alzheimer's disease, and in some cases, chronic lack of sleep causes weight gain, heart disease, high blood pressure, depression and diabetes.
Sleep is necessary because it allows the brain to develop and make neurological connections, improve the immune system to memory devices, process information and to rest the body.
But people do not take seriously sleep, seeing it as a waste of time. In an examination of the National Foundation for the Study of sleep, 43 percent of people said they almost never or very rarely manage to get some sleep on the weekend, and 15 percent of adults and 7 percent of children aged 13 to 18 said they sleep more than six hours per day during the working week.
In terms of how many hours we really needed to naspieme, scientists argue that individual, but generally speaking, women need to sleep longer than men, younger and much longer than adults. Otherwise, the body is tired and feel the need to sleep in small intervals throughout the day.
