Can a person sleep less and still be healthy?

It is important to ensure a normal amount of sleep every day, and the average adult should be between 6 and 9 hours. For example, going to bed at 10 or 11 o'clock at night and getting up at 6 or 7 o'clock in the morning can enable people to maintain a more stable biological rhythm, which is beneficial to the human body and mind.

There is no universal statement about the length of sleep. It can be divided into long sleep type (about 8 hours) and short sleep type (about 6 hours) depending on the person, in fact, 4 to 10 hours are within the normal range, mainly based on the next day after waking up full of energy. In fact, various groups of people have different sleep requirements.

Generally speaking, people aged 10 to 18 need 8 hours of sleep a day, 18 to 50-year-olds need 7 hours of sleep a day, and 50 to 70-year-olds need 5 to 6 hours a day. Especially for the elderly, it is a natural law that the quality of sleep is not as good as that of young people, as long as it does not affect physical health. As for how many hours of sleep you should sleep every day, depending on your physical fitness, as long as you are in line with your sleep habits, you can ensure that you are energetic during the day, and you do not feel tired after waking up.

Many great men, (it is said that Napoleon, in his free time during the day, took a nap to make up for the lack of sleep at night and to maintain energy) they slept very little, but they were energetic, because they mainly supplemented deep sleep, which was small in quantity but high in quality.

I've tried sleeping only 5 hours a day, and I've had to rely on chicken essence and the like to refresh me almost every day. But as the days went by, I gradually got used to getting up at what time I went to bed. As you get older, you feel that you don't have enough time, and sleeping becomes a waste of time (you can sleep as long as you want with your feet extended).

In fact, if adults can sleep for 5 hours a day, with exercise, health care, and a balanced diet, I believe they can maintain good health.

See how long you've been asleep. How can an adult ensure 6 hours of sleep a day, you can practice sleeping a little later every day.

Eight hours is normal, and there is no need to reduce it. Reducing will reduce the trouble, so why bother yourself?

In the real world, many of us have experienced drowsiness, sleepiness, and the feeling of not being able to open our eyes when we wake up. In this case, it must be a lack of sleep. Most people are well aware of the dangers of sleep deprivation, such as memory loss, weakened immunity, and unresponsiveness.

It is widely accepted that adults should get eight hours of sleep a day to maintain good health. But a recent study conducted by the University of California found that getting 8 hours of sleep a night is not bad for your health.

How long is the best amount of sleep? It's not 8 hours, which is surprising to anyone who knows the answer.

The best time to sleep is 6 to 7 hours a day, and an experimental study by the University of California found that people who slept 6 to 7 hours a night had significantly lower mortality rates than those who slept 8 hours or more, and those who slept less than 4 hours. People who slept for 7 hours had the lowest risk of dying, and even those who slept 5 hours had a lower risk of dying than those who slept 8 hours. In this case, sleeping too much is not good for the body, but rather slows down the body's metabolism.

Six to seven hours of sleep is ideal. Not only can people get a good rest and have enough energy to maintain normal work and life, but they can also avoid excessive sleep that damages their health.

Sleeping too long is harmful to long sleep, although the mind is resting, but the other parts of the body organs are still working. In particular, food that accumulates in the intestines during the night needs to be excreted after digestion. Prolonged sleep will allow these food debris to continue to stay in the intestines, allowing the intestines to absorb toxins from waste products, which will affect your health.

How long is the best amount of sleep? Not 8 hours, which is surprising to anyone who knows the answer, the most serious thing is that sleeping too much time also reduces the physical activity of the body. As a result, the heart may receive less blood and organs in other parts of the body receive less nutrients.

Due to the lack of blood**, these organs will be chronically deprived of oxygen, which will shorten the life span of the person.

Adults should choose 8 to 10 hours to get a good rest, and they will also get a very good body, they will not feel particularly tired, and they should go to bed before 11 o'clock every night to not stay up late.

8 hours of sleep is the most reasonable, so as to ensure the quality of sleep, will not be harmful to the body, but also ensure a healthy body.

About 8 hours of sleep is the most reasonable, because within 8 hours people's body functions can be restored and they can get a good rest.

In childhood, it is generally necessary to maintain about 10 to 12 hours a day, and it is generally recommended to start going to bed around 8 p.m. and take a nap as much as possible at noon. As older children get older, 10 hours or even 8 hours of sleep is sufficient. If children do not get enough sleep, they will not only lose energy and have low immunity, but also affect their growth and development.

Sleep, like air, water, and food, is a necessary physiological need for the human body's survival. Sleep well is listed as one of the top 10 healthy and strong by the WHO, and sleep is also a physical and mental health need.

The low pillow or flat pillow is not good, Sun Fu will put the neck in a state of excessive supine extension, so that sleeping is not only easy to have a puffy face, but also easier to breathe, easy to open the mouth to breathe, snoring, drooling, which is also not good for sleep. A few hours of sleep at night is the healthiest night. Some people sleep for four or five hours is enough, and some people sleep for six or seven hours and do not wake up, which depends on the person's physique.

Personally, I think that as long as you don't work during the day, have a clear mind and have vitality, this is healthy!

Sleep and health are closely related, and there is no way to talk about longevity without health; Sleep must be regular, fall asleep regularly, and get up regularly; Infants and toddlers "under 6 years old" are not less than 10-13 children; Childhood "6-10 years old" is not less than 11 children; In childhood, "10-12 years old" is not less than 10 young marquis; "Over 12 years old" in adolescence is not less than 9 hours.

There is no standard answer. Each person is an independent individual, and their physical state is different, and the results are completely different from person to person. If the next day is refreshed and energetic.

Then the amount of sleep for the first day is appropriate. On the contrary, You Qing needs to adjust the extension time. Common problems in the elderly are insomnia and dreaminess.

Dreaminess is the deterioration of brain function in the elderly: insomnia is caused by the decrease in the secretion of melatonin in the body, which is one of the factors of human sleep. Experts remind everyone:

The elderly who do not sleep well at night can develop the habit of taking a lunch break, not too long, not more than 1 hour.

8 hours of sleep is the most reasonable and healthiest to slip, because only *** own sleep time of 8 hours can make your own family body and body very healthy.

About 8 hours. If it's less than that, I think it's a lack of sleep. The second day will be very uncomfortable.

Sleeping 8 hours a day is the most reasonable sleep time to seep, and it is also good for the body, we are very energetic all day, very shouting sleepy excellent, very good. Thoughts.

Generally, everyone has a different sleeping time, and children generally sleep for a long time, but for some adults, it is necessary to ensure that there are eight hours of sleep per day.

8 hours of sleep a day is the most reasonable, because 8 hours of sleep can give you enough rest and relieve your fatigue.

If a person only sleeps 6 hours a day, according to scientific research, the most important thing is to ensure the quality of sleep at the beginning, because as long as you ensure that you will not be disturbed by the outside world at the beginning of sleep, then the impact of less sleep time can be minimized. In the book "Stanford Efficient Sleep Method", the concept of "**90 minutes" is proposed, and the most critical thing for high-quality sleep is 90 minutes at the beginning of sleep.

As long as no one is disturbed for the first 90 minutes, even if we only sleep 6 hours a day, we will get a good night's sleep. But if we are disturbed by the outside world, or if we can't sleep because of our own situation, then no matter how long we sleep, we won't have any energy the next day.

In order to improve the quality of sleep, you can go to bed at 12 o'clock at night and wake up at 6 o'clock in the morning. You can take a short lunch break at noon, why do you choose such a rest schedule? Because everyone is busy with work now, and many people have a lot of workload, which causes a situation of poor sleep quality.

In order to avoid this from happening, it is best to improve the quality of sleep at night as the main premise.

Let's talk about how to spend the day efficiently. In the morning, you can set two alarms, and points, the first alarm should be gentle; When you wake up to the alarm, open the curtains and wash your hands with cold water; Have breakfast and start your day. In the evening, after dinner, start soaking your feet, finish after 10 minutes, and then have fun or read a book for a while until you start to fall asleep.

Go to bed early and get up early is in good health, the plan of the day lies in the morning, I believe that with a good work and rest habits, the day will be a hundred times more energetic.

In the case of not harming health, you can try to eat a little less starch, so that you can be less sleepy, and eat more protein, so that you can also bask in the sun and drink more water, and how to reasonably reduce sleep time, there is a way to take one and a half hours as a cycle, and strive for an integer multiple of one and a half hours, that is, three hours, 6 hours, 9 hours, if you want to reduce your sleep time, you can first try to reduce sleep to 7 and a half hours, Then 6 hours depends on whether you can stand it, but it's best to focus on 8 hours, 8 or 9 hours is the best.

First of all, it should be clear that the human brain has a strong self-regulating ability, and compressing sleep time within a reasonable range will not have any negative effects on the body and mind.

When the sleep duration is shortened, the person's sleep efficiency will increase, thus making up for the lack of sleep time.

Therefore, if you are preparing for the college entrance examination, graduate school entrance examination, etc., you can appropriately compress your sleep time, which will not have a negative impact on your studies.

In 1989, psychologist Rachel Chafin et al. (Rechtschaffenet alThere have been a series of studies on people and animals to reduce sleep.

In the experiment, participants were asked to gradually reduce the amount of sleep they slept each day, such as 30 minutes every two or three weeks, until the volunteers did not want to reduce their sleep time again.

It was found that most people could reduce their sleep time to 5 hours per night.

After reduced sleep, the volunteers' performance on several test tasks was not significantly affected, and their mood and health remained good.

The study found that when sleep time was reduced to 5 hours per day or less, sleep efficiency increased. Volunteers fell asleep quickly, and the proportion of deep sleep increased.

Studies conducted in animals have found similar results: reduced sleep did not have significant adverse effects.

As a result, you can gradually shorten your sleep time. With a reasonable amount of sleep (five hours is probably the most basic night's sleep, but it varies from person to person), a small amount of sleep can still help you stay energized and healthy during the day.

Because when it comes to sleep, it has a sleep cycle. Every hour and a half to two hours, he has a fluctuating cycle. If you can get a good grasp of your sleep routine, you can do it.

If you choose a few cycles in the sleep center, for example, a normal person, he can go through 6 or 7 of these cycles every night. If you can control it, then he goes through 4 or 5 cycles and you save it, two hours or four hours. In this way, you wake up without harming your health, and then you get more sleep time, and you don't have one after you wake up.

A groggy feeling.

It is especially important to cultivate a regular schedule and not stay up late, especially to ensure quality sleep from 11 o'clock to 4 o'clock in the morning every night, the detoxification effect of the body's immune system is mainly carried out at this stage, and some hormones that affect the body are also at the peak of secretion at night, so at least ensure sleep at this stage.

During the day, you can take a nap, close your eyes more, exercise appropriately, pay attention to a comprehensive diet, and reduce your thoughts and mood swings before going to bed.

The best way to reduce your sleep is to increase your sleep level. You have a heavy study task now, but you must ensure that you have enough sleep time, the average adult sleeps 6-7 hours, and children must reach 8-9 hours. Good sleep habits are the best way to improve your sleep levels.

I hope you go to bed at 10 p.m. every night, wake up at 6 a.m., and sleep for 1 hour between 12 and 2 p.m. if you have time at noon. If you do this for a week, you will feel better and better and more relaxed in your studies. Good luck with good health!

Develop good habits.
