About a third of his life man spend in his sleep. In this time, he is protective and defenseless. But the night’s rest is essential für Köbody functions such as immune defense, healing, and Gedämemory formation
Vital energy-saving mode: No other creature schläft as deep as the human
Night für night diving, the people in your second, rätselhaftes life. The caps and their connection to the Außworld. How gelähmt, you are lying there, wäwhile your brain Selbstgespräche führt, and in your Inner whimsical images to life. "When sleep is not life a absolute important role, then he is the größte mistake the evolutionary process ever hat" made;, ruled work of the American sleep researcher Allan Law. Schließaddresses human and animal are never so defenseless.
The Fäability to sink into an unconscious, has verstä in the course of Evolution even;rkt. To awaken a slumbering man in his usual environment from the deep sleep, you’ll need a beträconsiderable Lautstärke. "No living creature we know, schläft so tief", the Tü says;binger researcher Professor Jan Born. But why we sleep üin General?
Näsmall energy-saving mode für diurnal creatures
The origin of the Bedürfnisses may simply lie in the fact that the earth pretending to be the majority of organisms, a rhythm of day and night. Flowers öopen and schließthe "Sonnenuhr", even some protozoa tick in your clock, sometimes more active, sometimes less. In the animal Kingdom, the one adapted to the bright, warm day, others developed to Geschöbounce of the night.
Für diurnal as human beings, it made sense, at night in front of the predators zurückzuziehen to remain motionless and to turn into a power-saving mode. However, this can be really the cause für a universal Bedürfnis to be? How strong this is, to show also the trick adjustments to the range of some animals. So dolphins are dormant with only a Hirnhähalf. Schließlich müyou need to sleep coming up for air. Zugvögel make it äsimilar.
"Lerchen" and "Eulen": Üremnants from prehistoric times
Also in the human snooze the traces of the prehistoric times. So fümany feel after the first night in a strange bed gerädert. The reason is that The left Hirnhähalf remains in a kind of Have, such as researchers in the US found out. The Schläfer is easier to awake. "The Ü us;survival gesichert", erklärt Dr. Hans-Günter Weeß, Director of the sleep centre in the Palatinate-Klinikum in Klingenmüwindow. Because in a strange place with new dangers were threatening.
Also differences in the sleeping behaviour nü were once;in addition. When snooze time is, says an internal clock that is ticking around in the 24-hour rhythm. In some people, this is something else. Chrono-biologists, such as the MüMunich sleep researcher Professor Till Roenneberg speak of "Lerchen" and "Eulen". As the people slept in groups, were able to beat will always be some Alarm.
However, whether with a Hirnhähalf or with both: Sleep müshot all the animals – from the thread of the worm to the whale –, if also different. Wäwhile the little pocket mouse 20 hours of the day, overslept, genügene the Giraffe for two hours. "The man is with his six to eight hours between the Asian elephant and the Hausschwein", so Weeß, the sleep already some Bücher has dedicated.
Lack of sleep schwächt the immune system
The energy of the main reason dafü is not save for sure;r, that we spend a third of our lives in the springs. "If we don’t sleep, die wir", Weeß says;. Experimentally nachshown this was not, of course. However, much speaks dafür. So weiß one of the rats that they spätesting, after two sleepless weeks on end. Your immune system breaks down, the Köbody temperature plays verrückt.
In the case of humans, there is a hereditary disease, in the case of victims of serious Schlafstöbrackets are haunted. After the Occurrence of the symptoms of this familiä ends;re insomnia within a few months, always töSouth. Many die of Lungenentzümaking. The cause of death fits perfectly to what you previously üabout the sleep weiß. So wä is formed, ;while we slumber, our Köbody defense. A party night schwächt, this is measurable. Test subjects were following vaccination through the night, developed a schwämore protection.
During sleep growth hormones ausgeschü are also;ttet and Schäthe repaired. "Wounds heal then schneller", Weeß says;. Anyone who suffers from a chronic lack of sleep, prone to high blood pressure, Ümountain guy, Stoffwechselstöbrackets and ill even häsingle-stage cancer. Our brain needs sleep to Müll get rid of. The Zwischenräume between the cells-wide, schäharmful products of metabolism, the tagsüabout arise, köcan be washed out.
Sinneseindrücke land in the Langzeitgedämemory
But erkläthe not rt, why do we lose sleep our consciousness. Gedämemory researcher Jan Born is the Rätsel for decades on the trail. "In sleep our Gedä forms;chtnis", erklähe rt. Countless Experiments have the bestäneeded. Especially in deep sleep, when our Brain vibrates in long Delta waves, solidify memories.
Sinneseindrücke, the tagsüber in the short-term memory of the brain to land, in the Hippocampus, in the Langzeitgedämemory of the neocortex anchored. This content will not be copied from one location to the other. "The Gedämemory formation is a höfirst, active Prozess", Born says. New experiences with old memories verknüpft, Unimportant things sorted out. But why not also in the waking state?
In the long term Gedäto form memory, müthe content is shot in short-term memory to be reactivated again. Measurements of the Gehirnströme make the visible. Wüauthorities at the same time Sinneseindrücke einströmen, köcould the problems führen. The result köcould hallucinations be – as they occur at sleep deprivation is often. Learning in your sleep is not a myth. It is everyday life.
Learning is in the sleep verknüpft
But happens even more. In an attempt ließ Born subjects of the series of numbers ergäcoins. Did you know that there is a pattern hid. Those who recognized it, quickly had the Lösung. After eight hours, the test persons had to compete once again. The one slept, the other had not. Under the Schläremote twice as many detected in the System. "In sleep a kind of synopsis passieren" must;, concludes Born. Üto sleep about something, so problems lösen.
We overslept, our life is meaningless, can be regarded as proven. Nevertheless, our society has a rather tense Verhäratio to the dark third of our lives. "We are seemingly meaningless in the sheets, wearing nothing to the economic success of bei", expert Weeß says;. According to surveys, Schlafstö are;conclusions längst to a popular disease. Because even if we don’t sleep our life perfect by cycles: at the push of a button. The way in Morpheus’ Arms führt only üa relaxed Release – above all, the desire to be in control. "Who wants to sleep, remains awake."
