A recent study by scientists from Germany showed that 15 minutes of sleep may be more beneficial than resting for two or even three hours. It turns out that many of the beneficial properties of sleep are manifested precisely in the initial stages, so a short period of time is enough to activate the activity of the central nervous system. But these are "extreme measures", since not only the brain should rest, but the whole organism as a whole.
Sleep in several phases
Some people can sleep several times a day, with waking time significantly exceeding the allotted for sleep. Nikola Tesla preferred 2 hours of sleep at night and 20 minutes of naps in the afternoon. Representatives of the Piraha tribe consider prolonged sleep unhealthy, so they sleep for short periods of time. Leonardo da Vinci's dream lasted from 15 to 20 minutes, and his periods of wakefulness were no more than 4 hours.
The above examples characterize polyphasic sleep patterns, for which specific periods of time are allotted over a 24-hour period. This method allows you to increase productivity time, but it also has some disadvantages.
Benefits of 15 minutes sleep
This technique allows you to give the necessary rest to the main body systems, to increase productivity in a short period of time. It promotes relaxation of the brain, accumulation of energy necessary for the performance of various organs. Some scientists believe that 15 minutes of nap is equivalent to a full hour of rest at night.
Studies by American scientists have shown that sleep in several phases should be practiced for no more than 5 months, since a negative effect on the body is possible. Since long-term studies have not been conducted, there are no data on the possible harm when using the technique for more than 1 year.
Another disadvantage is the period of adaptation to the new regime (from 7 to 10 days), during which productivity can significantly decrease. In addition, the frequency of food consumption, as well as portions, will increase.
People who have chosen polyphasic sleep for themselves are advised to stop drinking alcohol. You should also reduce your intake of coffee, tea and other caffeinated beverages. During the adaptation period, you should refrain from driving.
