How long does it take to sleep a day, and how is it best for your body?

In order to ensure deep sleep, you should try to go to bed early and wake up early. Although many white-collar workers are busy, it is better to start their working hours earlier than to end them later. Between 10 p.m. and 4 a.m., the best time to sleep is to fall asleep at 11 a.m.

After 11 o'clock, people will become more excited and have a harder time falling asleep. Two or three o'clock in the morning is the time when people who stay up late feel the most sleepy, and after dawn, people begin to enter a period of light sleep, when they begin to dream more and wake up easily. Some people like to sleep "back to sleep" to increase sleep time.

Of course, this is a way to supplement lack of sleep, and it should be reminded that "back to sleep" is mainly light sleep, and the effect is not as good as the deep sleep obtained by going to bed early and getting up early, and it is better to get up at 5 o'clock in the morning than to go to bed at 12 o'clock at night. 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 people, they sleep very little, but they have a lot of energy, because they supplement mainly deep sleep, although the quantity is small, but the quality is high. China's traditional health science advocates sleeping "meridian sleep".

"sub" refers to 23 1 o'clock at night, and "noon" refers to 11 13 o'clock during the day. It is believed that sleeping in the "sub-hour" can nourish energy, and sleeping in the "noon" can conform to the development of yang energy.

From a health point of view, sleeping for four hours is not good for your health. The latest research has found that adults should sleep a little more than 7 hours, which is the most suitable for the human body and is beneficial for longevity. It is generally believed that more than 80% of adults sleep for about hours a day, teenagers need more, teenagers need about 8-9 hours, and children need more, children need 10 hours of sleep.

But this is only for most people, there are individual differences. Some people take short sleeps and only need 4-5 hours of sleep every night. These 4-5 hours of sleep will not cause any physical discomfort to these people, so there is no need to force 6-7 hours, or 7-8 hours of sleep, so that they will feel uncomfortable.

Some adults may need to sleep for a longer period of time, perhaps 9-10 hours. This is a long sleeper, accounting for about 1%-3% of the population. So how long you sleep depends mainly on whether you can sleep well, and you can be clear during the day, and you don't feel tired or sleepy, so you don't have to worry too much about how long you have to sleep.

Moderate sleep time is best.

Sleep should generally be maintained for 7 to 8 hours, but it is not necessary and should vary from person to person. Those who fall asleep quickly and sleep deeply, and generally have no dreams or few dreams, can fully recover their energy after 6 hours of sleep; People who fall asleep slowly and have many light sleepy eyes, often dream and nightmares, even if they sleep for 10 hours, it is still difficult to be refreshed, and they should go through various ** to get effective sleep, but prolonging sleep time is harmful to the body. Since everyone has a different biological rhythm, the arrangement of sleep in the morning and evening should be different from person to person!

In fact, different circadian rhythms cause two conditions of sleep, namely "night owls" and "larks". Adapting to this circadian rhythm is good for work efficiency and quality of life, and vice versa, it is bad 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.

Sunny, hot days with short sleep durations; Bad weather, such as rainy days, cooler winters, and long sleep hours. With the increase of altitude in the area, the sleep time decreased slightly; With increasing latitude, sleep duration is slightly longer.

In fact, sleep problems still vary from person to person, and everyone's physical condition is different, so the time of sleep should also be adjusted.

The average adult sleep time under normal circumstances, I personally think that about seven hours can be enough, more than seven hours or less than seven hours, it is a relatively unreasonable state, because, after you sleep too much, you will enter a state of drowsiness, you feel that your sleep time is enough, but your body will let you continue to enter the state of sleep, in fact, this is an adverse reaction, at the same time, if you do not reach seven hours of sleep time, Then your energy at the end of the day is not enough. <>

The sleep time of the elderly is relatively short, which is not that the elderly do not want to sleep, but when they rest to a certain time, the body's natural response will make them wake up, generally speaking, this time cut-off point is about six hours, this amount of time is more than enough for the elderly to carry out normal social activities.

For infants and toddlers, the sleep time may reach about 16 hours, after all, we all know that infants and young children have no other social activities, and long-term sleep is good for their growth and development, and the time of primary and secondary schools is probably in.

Eight or nine hours, in this age group, I personally recommend that parents should strictly enforce, although children in this age group already have heavy academic pressure, but sufficient sleep time is very good for their development and good physical and mental health. <>

In addition, there are some people who love sports, for this group, my personal suggestion is to do what you can, based on your own feelings, mainly without the so-called fatigue, and there will be no negative impact on the mental state.

In the final analysis, the problem of sleep time is adjusted according to one's own state, although there will be a relatively reasonable range from the data, but after all, it should be based on body feeling. <>

7-9 hours. Because 7-9 hours of sleep is enough.

The optimal amount of sleep each person can get each day varies greatly, and it is related to many factors such as personality, health status, sleep habits, work environment, labor intensity, etc.

Adults are generally 6 to 9 hours, and children need more sleep than they get, and newborns can sleep up to 20 hours.

1.Newborns: The average sleep time per day is about 18 hours (16 to 20 hours).

2.Infants: Sleep is shorter than that of newborns, about 9 to 12 hours by 2 years of age.

3.School-age children: Sleep about 10 hours a day.

4.Adults: The duration of sleep varies greatly from person to person, usually ranging from 6 to 9 hours, and 8 hours of sleep is generally considered appropriate.

5.Older people: sleep time is often reduced to 6 hours.

As we age, we are more likely to suffer from some diseases, such as prostatic hyperplasia in men, which leads to more frequent urination at night and interferes with sleep at night. As a result, nighttime sleep time may decrease overall, while daytime sleep time may increase relatively while total sleep time may remain stable.

8 hours is the best for the human body, 8 hours can give the body enough rest, and it will not be too dizzy.

Because each person's sleeping habits and sleeping environment are different, there are individual differences in the amount of sleep time per day, and the daily sleep time of minors is usually controlled at about 8 to 10 hours; Young and middle-aged people usually sleep 7 to 8 hours a day; The sleep time of the elderly will be relatively reduced, and the sleep time will also decrease, generally about 6 hours.
