Our night sleep consists of 4-5 cycles, each cycle is divided into phases of slow and fast sleep. During the phases of slow sleep, muscles relax, brain activity decreases, but the phase of fast sleep, which occupies about 20% of total sleep, is the most intense. In this phase, rapid movements of eyeballs occur (which is why it is also called the BDG phase) and the most colorful dreams. A quick sleep takes about 10 minutes in the first cycle, and then increases to 20 minutes with each cycle. And for this time a person can see a situation picture, which is equivalent to several days, i.e. In the fast sleep phase, you can see how you spent many days at work, and so on, in a few minutes. Maybe that's why the eyes are moving so fast in this phase, but the paradox is that the eyes in a dream are moving also for people who are blind from birth.
Condition of fast sleep
A quick sleep is the most necessary for restoring the body's strength. In this phase, only the brain is involved, and almost every muscle in the body is relaxed and resting. In addition to recovery, the fast phase of sleep allows you to better absorb the information received for the day. That's why the students are so important full sleep, and if you "cram" all night - the result will be zero.
The technique of fast sleep
To quickly cause a phase of fast sleep and restore body strength in just 4-5 hours rest, it is necessary to observe several rules. You can not eat up before going to bed, because food requires energy and active work of the intestinal tract - so your muscles will not be able to completely relax. Try, falling asleep, not to think about problems, but to present nice pictures - you can make mistakes or dream. Be sure to take care of comfortable conditions - you should be comfortable, soft and warm, the perfect solution - a water mattress with heating, on which the body takes the most natural and relaxed poses.
