The great Renaissance creator, Leonardo da Vinci, had time the most valuable thing. He needed hours to work with ideas, so he thought he would take some hours of sleep.
Thus he created a new sleeping system. He slept for 15 minutes every four hours. He practiced this method for years and did not feel tired at all. He slept many times during the day, but by little. As a result, Da Vinci slept an hour and a half a day and all the other hours dedicated him to his productive work.
As is known to all, man is more productive after sleep. His abilities are greater. By interrupting the day to sleep a little bit, man is added to the productive ability.
After many years of experimentation, those who followed the Da Vinci sleep method have proposed how to alternate sleep with productive hours.
Sleep 30 minutes every 6 hours (dymaxion method)
Sleep 20 minutes every 4 hours (uberman method)
Sleep at night for 1.5 to 3 hours and during the day 3 times out of 20 minutes (everyman method)
Sleep 2 hours during the night and 20 minutes in the afternoon (tesla method)
Sleep 5 hours at night and 1.5 hours in the afternoon (siesta method)
All methods are effective. It should be noted here that each body responds differently to sleep time, so it should be found most suitable for you.
