For good health and well-being, proper sleep is a must. Unfortunately, with the modern rhythm of life, it is not always possible to ensure a good night’s rest.
It used to be thought that a full sleep should last about eight hours. So everyone has to spend almost a third of the day in bed? It’s not obligatory. There are special techniques that allow you to fully restore strength in a shorter time.
Sleep phases
Before you begin to study the methods of accelerated sleep, you should get acquainted with its structure. Sleep consists of two phases: REM and non-REM sleep. Each of these phases is necessary to maintain a full life and a complete rejection of one of them can lead to unpleasant consequences.
In the phase of REM sleep (“rapid eye movements”), which lasts about 20 minutes, recovery and optimization of brain functions occurs. During this period, the brain processes all the information received during the day. It is during REM sleep that a person sees dreams that are products of his own brain.
During slow sleep, the entire body is restored as a whole. In this phase, the hormonal and immune statuses are corrected, leukocytes and interleukins are formed that protect the body from infections, skin cells and the gastrointestinal tract are actively restored. The absence of this phase can lead to frequent viral and colds, diseases of the cardiovascular and endocrine systems. If you wake up a person in the phase of slow sleep, then he will feel tired, sleepy and lethargic.
How to sleep less and stay healthy?
A short nap can also become fulfilling if organized wisely. There are several techniques based on reducing sleep time due to the slow phase:
- The Siesta system involves the organization of a short daytime sleep and a long nighttime sleep. Daytime sleep should last no more than 20 minutes — during this time the brain will have time to recover and, as a result, the time of night rest will be reduced by a couple of hours;
- ladder system. The principle of this system is similar to “Siesta”, but there should be several sessions of daytime sleep. So, if you want to reduce sleep at night by 4 hours, you need to arrange two twenty-minute sleep sessions during the day;
- The “superhuman” method of sleep involves reducing the night’s rest by several short sessions of sleep during the day. This technique is very difficult for the body, it cannot be used for a long time due to the danger of symptoms of nervous overwork;
- the use of special alarm clocks and applications that control sleep phases. Today, a huge number of “helpers” have appeared that will help you wake up at the end of REM sleep. Their use is absolutely harmless and is an excellent prevention of chronic fatigue.
