For a long time, the internet has been circulating a called " da Vinci sleep method" sleep method. This method of sleep is named after Leonardo da Vinci, a great man with many titles, such as scientist, artist, inventor and so on. According to legend, da Vinci sleeps 15 - 20 minutes every four hours, so that he sleeps only about two hours a day, and has plenty of time to do his work and stay energetic. This kind of sleep is actually a polysphasic sleep, which means that the whole sleep time is divided. Many superstitious people hope that this method of sleep through it to shorten the overall time of sleep, at the same time, people's mental state can and sleep for nine hours in a row of single-phase sleep, you can have more time to work and study.
However, by searching you will find that there is no reliable evidence that Leonardo da Vinci is using this sleep method on a long - term, regular basis, other than the article describing the da Vinci sleep method.
Although many people claim that this polyphase sleep can greatly improve productivity, not everyone is willing to take their own example. The only documented long-term da Vinci sleep was performed by buck minster fuller, an engineer and designer. He published his two-year sleep plan in time magazine in 1943. During this time, he sleeps 30 minutes every six hours, which means he sleeps only 2 hours a day. In the end, his plan had to be terminated because his business partners tried to stop, because his schedule and others are too inappropriate. It is not known whether fuller followed what he called his sleep plan, but he was the first person ever to actually report successful polyphasic sleep.
The most recent notable polyphase sleep experimenter is Steve pav Lina, a prominent blogger. He insisted on multi-phase sleep for more than two months, a total of only three hours of sleep a day, and published his own sleep log on the blog. He said it was difficult to adapt at first, but by the second half of the experiment the body gradually adapted to the sleep cycle, also can keep awake at night. But towards the end of the experiment, he tried to reduce the number of naps to make sleep shorter, but often can't hear the alarm clock and sleep directly for six hours. It seems that it is not easy to keep a record of polyphasic sleep for a long time.
