How many years does a person have to sleep in a lifetime, and how long does a person have to sleep i

Sleep for a lifetime, when you live, when you sleep, and when you die, you will always "sleep" and be satisfied.

About one-third of a person's life is spent in sleep, which seems to be a fundamental element of biology, but scientists still don't know why they sleep. According to the British magazine New Scientist, scientists have come up with several theories about the cause of sleep, ranging from simple theories to complex theories involving memory processing, but none of them have been confirmed. Sleep is made up of two completely different states:

One is fast-wave sleep, when the eyes are constantly turning and the brain is very active, and most dreams appear during this period; The other is slow-wave sleep, which is a deeper state of unconsciousness. The roles of the two states are obviously different, but they are inexplicably intertwined. In natural sleep, slow-wave sleep is always followed by a period of fast-wave sleep, so it's likely that their functions are interrelated in some way.

Sleep is at the service of the brain. One of the reasons is that animals sleep and plants do not sleep, and other organs of the human body, such as muscles and liver, do not rest. This year, scientists have confirmed that the cerebellum sleeps.

This suggests that sleep is a brain-wide phenomenon, and researchers are beginning to agree that at least slow-wave sleep is the time when the brain repairs free radicals and causes damage. Free radicals are by-products of metabolism and can damage the body's cells. Other organs can mend this damage by giving up and replacing damaged cells, but the brain can't do that.

Therefore, slow-wave sleep is like a team that repairs a highway at night, working in the dead of night. So what is fast-wave sleep? Some researchers have suggested that this is a tinkering made by the brain when examining slow-wave sleep.

Other researchers believe that it is related to early brain development, but they do not know for sure. It seems that this issue will have to be left to be resolved later. The Importance of Sleep:

In modern society, the pace is tense, and more and more people are bothered by poor sleep, and improving sleep quality has become a top priority. Sleep can replenish physical strength, napping is the happiest habit, like first love and hot love: sleep at night, like a stable relationship, soothing the soul; Insomnia is the same as falling out of love, feeling sad every night, long nights, when to wait until dawn?

This is a very vivid statement, but in fact, sleep is more important than love. If you don't eat, you can live for 20 days, if you don't drink water, you can live for 7 days, and if you don't sleep, you can only live for 5 days.

People from 1 --- 80 years old sleep for about 30 years (let's give points).

Sleep six to eight hours a day, which means that a person spends a quarter to a third of his life sleeping. So how long it depends on how long you can live.

The average human sleeps 8 hours a day, and sleeps two-thirds of the day, and sleeps for an average of 27 years out of 81 years in a lifetime.

About 1 3 hours of life are spent sleeping, people have to sleep enough for 7 8 hours a day, basically 1 3 of the day sleeping

People spend a third of their lives sleeping, and adults sleep less than babies and the elderly, and people sleep all year after year according to the average age in our country.

Adult sleep duration.

It should generally be maintained for 7 to 8 hours, but it is not necessary to force it and should vary from person to person.

Those who fall asleep quickly and sleep with deep sleep and generally have no dreams or few dreams can fully recover their energy after sleeping for 6 hours; Falling asleep slowly and lightly, with many sleepy eyes and frequent dreams.

Nightmares, even if they sleep for 10 hours, it is still difficult to refresh their spirits, and they should go through various ** to get effective sleep, but prolonging sleep is harmful to the body. Since everyone has a different biological rhythm of the mu model, the arrangement of sleep in the morning and evening should be different from person to person! In fact, different circadian rhythms cause sleep to occur in two ways, namely "night owls" and "larks."

Adapting to this circadian rhythm is conducive to improving work efficiency.

and quality of life, and vice versa, not good for health.

According to the medical theory of the motherland, it is advisable to go to bed late and get up early in spring and summer, and you need to sleep 5 to 7 hours a day; In autumn, it is advisable to go to bed early and get up early, and you need to sleep 7 to 8 hours a day; In winter, it is advisable to go to bed early and wake up late, and you need to sleep 8 to 9 hours a day. Conform to the laws of natural growth and collection.

Therefore, as long as you are refreshed and happy after sleeping, that is the best time for you to sleep.

People 7 to 8 hours a day, so.

If 7 hours a day:

7 365 = 2555 hours.

If 8 hours.

8 365 = 2920 hours.

It should be: between 2555 hours and 2920 hours.

Under normal circumstances, eight hours of sleep, according to eight hours of sleep a day, 2920 hours of sleep a year is enough.

Calculated as 8 hours of sleep per day:

8 365 = 2920 hours.

Total in a year: 24 365 = 8760 hours.

A normal person has about 7 hours a day and no more than 8 hours, except for lunch breaks. (Lunch break for one class time, it's fine.)

If you live a normal life, sleep 8 hours a day.

If you live the life of a robot, sleep 3-4 hours a day.

If you live like a pig, you can sleep more than 12 hours a day.

If you are a person in the soil, you should sleep 24 hours a day.

Not necessarily 8 hours a day is better.

Normally, 7 to 8 hours, how much each person has a little difference, Sunday, the holiday will be lazy, roughly calculated.
