◆ "Father of sleep research" Nathaniel Klitman
Nathaniel Klitmann, who is said to be "the father of contemporary sleep research"REM sleepOne of the scientists who revealed the existence. Until Mr. Klitmann engaged in sleep research, the definition was not clearly defined with the recognition that sleeping is not any condition of "wake-up, unconsciousness, death". Mr. Klitmann's initial experiment was to conduct physical and psychological durability tests on subjects who did not sleep for days.

Mr. Klitman himself also participated in the experiment as a subject, and continued to wake for 115 hours longer than anyone else, as a result, I discovered that "human beings see hallucinations when the state of sleep deprivation becomes more than a certain amount." In addition, I have lived underground for 6 weeks to see if I can live on "28 hours a day", but the experiment has failed.

◆ Presentation of "REM sleep" and progress of sleep research
In the early 1950's Mr. Klitmann met a student named Eugene Azelinsky. As a research for the thesis, Mr. Azelinsky observed the person sleeping using the early EEG diagram, and found that there was a point where the eyes of the sleeping person move violently back and forth.

Mr. Klitmann who was interested in this research worked with Mr. Azelinsky, and in 1953 this phenomenon was called "Rapid Eye Movement sleep (REM sleep)We announced it to the world as. REM sleep is the state in which the brain is active with the body asleep, besides the brainAlpha waveFrom "stage 1" to give out,Delta wave"Stage 5" that emanates the stage, sleep stage is found to be.

As a result of the drastic progress of sleep research, many researchers have started on the field of "sleeping" and also studied sleep modes of nonhuman animals, such as "Bottlenose dolphins are half drowned because they are not drowned" Has advanced.

As new technologies on sleep are born, as of 2014 there are over 2000 sleeping specialized clinics in the USA,National Academy of Sciences, It is speculated that 50 to 70 million Americans suffer from chronic insomnia disorder. The US Department of Transportation announced that the accident caused by "DWD (Driving While Drowsy)" driving in sleep deprivation state, over 1,500 people dead in the United States alone, and more than 40,000 injured people in the United States alone doing.

◆ What is the correct sleep cycle?
Also, Associate Professor Matthew J. Wolf-Meyer of the Department of Anthropology at the University of California at Santa Cruz conducted research on the sleep cycle. We interviewed medical professionals and patients involved in sleep research for four years,The Slumbering Masses"It summarized it in a book called. In modern people's life it is thought that it is a healthy sleep cycle to get up at 7 o'clock while sleeping around 23 o'clock, but Mr. Mayer insists that this is a mistake.

The human race up to about 150 years ago lives in the cycle of taking "first sleep" from 4 hours to 5 hours when the sun goes down and taking "second sleep" during the day,Benjamin FranklinHe liked this sleep cycle as well. Mr. Meyer is a modern8 hour labor systemPointed out that sleep is not getting enough and accuses American capitalistic aspect.

◆ Lark type and owl type
"Internal TimeMr. Till Loenberg also criticized the modern working hours as Mr. Mayer, and the human body clock wakes up at dawn asleep at sunsetLark"Type or the" owl "type that sleeps late at night and happens late in the morning.

ByBecky EnVérité

Work starts at 9 o'clock in the morning is a suitable environment for people with a lark-type body clock, but owl-shaped people will get up earlier for 2-3 hours than biological clocks. Mr. Loneburg said "Social jet lagI call it. Through 'social time zone bokeh', people of the owl type will be sleeping over the weekend to regain lack of sleep on weekdays, while lark-shaped people are staying up late on weekends Friday and Saturday I can not sleep well at the weekend, and finally I will be able to rest my body from Monday.

Because teens are often owl-shaped, Mr. Loneburg claims that efficiency, motivation and attendance rate will rise by shifting so that the high school timetable starts late in the morning, and indeed this At the school in Minnesota state where time schedule was introduced,SAT (university admissibility test)Has risen by more than 200 points. However, because teachers and school administrators can not understand this effect, Mr. Loneburg thinks "It will be difficult for the timetable to be changed in general."
