How much time you need to sleep, each person decides for himself. The individual duration of sleep is also determined by the way of life, occupation, health status and climate of the country in which the person lives.
Statistics
Long studies and disputes between scientists on the issue of "how much sleep should be" led to the conclusion that the most healthy people are those who sleep about 6-8 hours a day. These people have lower mortality and cardiovascular disease. But for those who sleep less than 4.5 hours, life expectancy is reduced 1.6 times. Finding out how many hours to sleep, scientists were able to notice an interesting fact that sleep lasting more than 9 hours carries a great danger to the body. Such a duration of sleep shortens life by at least 1.7 times.
Factors that determine the duration of a healthy sleep
The reasons that cause a bad and unhealthy sleep can be different: an overly hot blanket, a stuffy room, an overly soft mattress, a bad mood (depression), a dirty body, or bedding.
The state of health is affected not only by sleep conditions, but also by how many hours a person is used to sleeping. This is always reflected in the quality of life.
Constant going to bed after midnight causes disturbances in brain activity, which negatively affects mental abilities and leads to chronic fatigue and, as a result, to an earthy complexion, dull look, constant headaches, lethargy, bad taste in the mouth, and malfunctions digestive tract and cardiovascular system.
If memory begins to deteriorate, which is a sign of depletion of brain functions, a person must determine how much his body needs to sleep.
Nervous exhaustion due to poor sleep often leads to the development of instability of mental reactions: conflict, tearfulness, anger, which is more pronounced in women.
How much to sleep and when to shower?
Full sleep time varies by age group. A person aged 20-50 needs to sleep about 8 hours, and for elderly people, 4 hours can be enough.
An individual feature of each person is daytime sleep. How harmful or useful it is, it is impossible to say unequivocally. It is known that sleeping at sunset is even dangerous, as this leads to a reduction in life expectancy, as the ancient scriptures say.
It should be noted that the solution to the question “how much time you need to sleep” is not always sufficient, because the amount of sleep will never replace its quality. The most important sleep interval is considered to be a dream until midnight, which contributes to deep relaxation of the body, proper rest, restoration and replenishment of health reserves.
Therefore, try to go to bed before 24 hours to already be in the phase of sound sleep before this time of day. Sleep quality up to 24 hours is two times higher than after midnight. Thus, how much we need to sleep depends on how much we go to bed.
Pay attention to an important point: if you wake up in bed for more than 30 minutes after waking up, the vitality of the body and the volitional qualities of a person are significantly reduced.
The secrets of sleep must be known for the concentration of mental forces. And already psychic energy contributes to the manifestation of willpower, the power of the mind, which affect the realization of human desires and his abilities. There are people who try to scream for something, but more often than not, no one hears them or wants to listen to them. Others, in almost a whisper, are able to drop the phrase that will be heard, and the will of the person will be fulfilled. Have you already decided for yourself how many hours you need to sleep?
