How do I know how long I need to sleep?

The human body has its own biological clock and regulator, and in general, if you go to bed at one point in time and get up at one point in time for a long time, you will feel sleepy and wake up naturally after a long time. We feel that when we wake up at noon, it is because our own schedule is irregular, either too tired, or too late to brush Douban at night, and there are no good habits. So if you want to check how much sleep you need, start by overcoming procrastination and having a regular schedule.

When the time comes, force yourself to sleep (except for the next day, you must hand in the work task), if you wake up naturally, such as your alarm clock is set at half past seven, but you will wake up naturally at half past six, some people want to go to bed early and go back to sleep, in fact, this is harmful, because natural awakening shows that the rest that the body needs is enough, and returning to the cage will make you wake up in a daze by the alarm clock, and accompanied by getting up gas, and even miss the time, resulting in a bad spirit of the day, chaotic arrangements, don't care what time it is, get up immediately, make a plan for the day, Eat breakfast, read, have more time and jog for a few minutes. Keep yourself refreshed throughout the day. <>

I've also been bothered with this issue for a long time. You're not waking up naturally, it's "sleep compensation". I did an experiment by myself, for a month, without relying on the external time rhythm system, I slept naturally, woke up naturally, recorded it with software, and found that:

In an average of 8 hours plus or minus 1 hour. It does not shorten the sleep time because it does not do energy-consuming things during the day, but it does delay the time of sleep, so that the start and end times of sleep are not fixed during the month. I can't yet:

Why do people sleep Different people do not have the same need for sleep time (different ages) How the body determines how long you should sleep. But there is a discussion on Zhihu about how the human body recognizes the cycle of day and night. I'd love to know these answers as well.

So far, the results of my own experiments have been that sleep time can be overdrawn, not stored. <>

Under normal circumstances, it takes about 10 hours for children and about 7 hours for adults. And the old man is about six hours. This is generally the case.

But specific to each person, it should be different, because some people have to work overtime frequently, so each person's specific situation should be different, there is also a biological clock, some people get up early and work in the dark, so he gets up early in the morning and goes to bed early at night. In short, the average sleep should be about seven hours, and the normal standard should be the next day, when you are more energetic and not sleepy, and you can reach this level, then this kind of sleep time should be relatively normal and it is also a standard for judging how much sleep you need.

The quality of a person's sleep is important. Because good sleep helps to keep the body healthy, improve immunity, make people energetic, work more handy and smoother.

Generally speaking, 11 p.m. to 6 p.m. is the most appropriate place to sleep for four or five hours a day.

Hello. It definitely takes time to sleep by yourself, and the minimum is generally 6 hours, so it is better for us to get enough sleep.

If you want to judge how much sleep you need, you need to see whether you are refreshed after sleep, and good sleep quality can bring energy to the day.

The standard sleep time is from 10 p.m. to 6 a.m. the next morning, during which falling asleep is conducive to the rest of the body's organs, metabolic repair, hormone secretion, and the stability of metabolic levels in the body. The average adult can sleep 6-8 hours to replenish physical strength and meet the physical needs of study and work the next day.

Judge your sleep time, this can determine your rest time according to your recovery after resting, and according to your mental condition!

When your body is tired, dark circles, yellow, and no energy, you should pay attention to rest and combine work and rest.

The average person needs to sleep at least 8 hours a day to recuperate, let the body organs rest, promote gastrointestinal digestion and blood circulation, and improve the body's immunity.

The spirit of work is measured by the level of fatigue, for example, if your fatigue level is not so severe, and the integration of memories can also help. The next day, you will have the energy to go to bed late and stay up late after twelve o'clock. This will only make the body worse and worse.

If you are very tired during the day and do hard work, then you should sleep for 8 or 9 hours, if you are not tired during the day, then you can sleep for 7 hours, and see if you are tired for a day.

The time that people need to sleep is determined according to their age, and also according to the intensity of their labor and study during the day.

If you want to determine how much sleep you need, then measure it by your mental and fatigue level during the day, for example, if your fatigue level is not so severe and you are not sleepy, that is the right sleep time for you.

Summary. Hello dear! How long to sleep! The normal sleep time of a person is 6-8 hours a day, and generally speaking, the sleep time of a person is constantly decreasing with age.

Hello dear! How long to sleep! The normal sleep time of a person is 6-8 hours a day, and generally speaking, the sleep time of a person is constantly decreasing with age.

The sleep time is 18-20 hours in infancy, 10 hours in elementary school, 8-9 hours in middle school, and 6-8 hours in adulthood. It is generally recommended that 8 hours is better. However, in general, the sleep time will be reduced after old age, and some elderly people can sleep for 5-6 hours.

There is another criterion for judging whether the sleep time is enough, which is to see whether the mental state of the next day is good. If it does not affect your study and work, your mood is relatively happy, even if you sleep less than 6-8 hours, it is still normal.

Adults sleep 8 hours a day, and children aged 6-13 years sleep 8-10 hours appropriately. As we age, we get less sleepy, and many older people get enough sleep for 6 hours. Sleep time varies from person to person, so it's better to stay energized during the day.

In addition, the daily sleep time of adults varies greatly due to work and lifestyle habits, which fluctuates around 5-8 hours. While most people may get 7-8 hours of sleep, some people need 8-9 hours or more of sleep to feel sufficient, while others get comparatively less sleep and 4-5 hours of sleep feel sufficient. At this time, it should be judged according to the situation of waking up the next day, if you feel full of energy after waking up, no longer sleepy, and can concentrate on your work and life during the day, it proves that your brain and body have been rested enough at night, and the sleep time of the previous night can meet your needs.

If you wake up with headaches, sore eyes, and low energy, it means that you haven't rested well. If you feel dizzy after thinking about it, although you are not sleepy but you are not motivated, it means that you have slept too much, and you can get up early appropriately.

<> How to Know How Much Sleep You Need.

Getting enough sleep can prevent health problems, and the University of Chicago did an experiment in which volunteers slept only four hours a day for six days and recorded their changes, short-term sleep deprivation leads to difficulty concentrating, unresponsiveness, vision loss, driving difficulties, irritability, and memory loss, and chronic sleep deprivation can lead to obesity, stroke, memory loss, and heart disease.

Sleep needs are judged by age.

As we age, we need less and less sleep, with newborns sleeping between 11 and 19 hours a day, while people over 65 sleep the least, ranging from 5 to 9 hours a day. But everyone is unique and can always be affected by different factors that cause the amount of sleep needed to be greater than what is generally accepted to be normal.

The amount of sleep you get can change due to certain factors.

Sometimes stress and physical changes can also affect the amount of sleep needed, including illness, injury, intense physical exertion, emotional distress, or a lot of mental work, and getting a little more sleep at night to meet these additional needs.

Do a little sleep experiment (1).

Find the first and second day is a weekend or vacation time, don't set an alarm clock, sleep until you wake up naturally, most people will sleep longer on the first day, maybe even more than 16 hours, that is because your body is in a state of "lack of sleep", if the phenomenon of lack of sleep is very serious, before the experiment, make up for these sleep, and then take the test.

Do a little sleep experiment (2).

As mentioned above, you will sleep longer than normal on the first day, and the next day, choose the same time to fall asleep, or no alarm clock, and after a few days, you will gradually wake up naturally at the same time. This way you know how much sleep you need in a day, and the results of the experiment are not available in one day, but need to be verified over many days.

Lack of sleep is actually not getting enough sleep every day, and then accumulating day by day.

You may only miss a few minutes a day, or a few hours of sleep. This lack of sleep can be accumulated for a short period of time, or it can last for months, staying up late for work, study or play, and being woken up by the alarm clock the next day because you have to get up, this is the cause of your sleep deprivation, and you need to record the amount of sleep you miss every day. Of course, first of all, you also need to know how many hours of sleep you need in a day.

Be sure to learn to catch up on sleep.

Arrange a vacation for yourself, don't do anything, go to bed on time every day, sleep until you wake up naturally, make up for your lack of sleep, and go to bed on time every day, you will find that even if you don't have an alarm clock, you can wake up naturally on time every morning, provided you sleep early enough to meet the required sleep time.

There are many factors that affect it, and there is no standard answer to how long you should sleep each night. The most important thing is to form a regular sleep and have a stable biological clock, and more is not always better.

Because of the different personal conditions and physical fitness, everyone's sleep time is also different, some people's sleep time is relatively short, usually 7 hours of rest can meet the body's needs for sleep, but young people are best to meet 8 hours of sleep time, the general work and rest is from 22 o'clock to 6 o'clock, is more suitable for the human body's sleep time, and the sleep time is reasonable is also good for their own health, which helps the liver to better produce blood.
