What is the best hours of sleep for a person, and what is the best time for a human body to sleep?

Normal people should sleep for about 6-8 hours, and teenagers should sleep for a relatively longer time, about 8-10 hours is more appropriate, because teenagers need to grow their bodies and enough sleep can make the release of growth hormone more favorable, thereby promoting growth and development, which has many benefits for the body.

A normal person's sleep time is generally 6-8 hours. If the sleep time is less than 6 hours and more than 9 hours, it is abnormal, less than 6 hours is considered sleep deprivation, and more than 9 hours is considered excessive sleep time. The optimal amount of sleep is 8 hours.

In fact, I think it's best to sleep 7 or 8 hours as an adult, because I am already very tired from my usual work. For children, I think I'll have to sleep a little longer, because I'm still growing up, so it's about 8 or 9 hours.

It is recommended to sleep 6-8 hours a day, and if it is an adolescent, it is recommended to sleep for 8-10 hours, because adolescents need to grow their bodies, and long nighttime sleep is conducive to the release of growth hormone, which is beneficial to the long body.

Adults generally get enough sleep for 6 to 8 hours.

9 to 10 hours for the youngest child, and 8 hours for the older child in junior high school.

The above time refers to the time after falling asleep.

Generally speaking, children should be more than 9 hours, middle-aged people should be more than 7 hours, and elderly people should be more than 5 hours.

The optimal sleep time for the human body is 6 to 8 hours.

Adults should sleep for 7 to 8 hours.

The duration of sleep varies from age to age, with children sleeping longer, teenagers sleeping at least eight hours or more, and adults sleeping for six to eight hours.

The amount of sleep varies for each age, and when it comes to growing your body, it's best to get ten hours. When you are young, seven to eight hours is recommended.

From a medical point of view, the best time for a person to sleep is generally 8 to 10 hours, and if it is half an hour less, it will be sad.

The average sleep time is 6 to 8 hours, but some people may only get 4 or 5 hours of sleep.

The best sleep time for the human body is generally 8 to 10 hours, and the elderly should sleep more.

The best sleep time for the human body is about 8 hours, and sleeping too much is not good, and too little is not good.

Seven to eight hours is about the same!

7 to 8 hours of sleep is best.

Ten p.m. to seven a.m.

Many people think that they need to sleep for 8 hours a night to get enough sleep, but this is not the case, because everyone's perception of sleep length is different, some people need to sleep for 8 hours, and some people sleep for 5 hours to be energetic, so they can only give an average range according to the relevant statistics as a reference:

Infancy: 14-18 hours.

Early childhood: 11-14 hours.

Childhood: more than 10 hours.

Adults: 7-8 hours.

The optimal amount of sleep varies greatly from person to person.

First we need to understand the four types of biological clocks:

1.Dolphin type. Dolphins sleep with only half of their brain at rest, and the other half of their brain is alert to control swimming, predation and other behaviors, so this type is also known as unilateral hemicerebral sleep, especially suitable for insomnia patients - they are highly intelligent, slightly nervous, very shallow sleep, and have low sleep urges.

2.Lion type. Lions at the top of the food chain like to hunt in the morning. This type is suitable for people who are used to waking up early, they are generally more optimistic and have a moderate urge to sleep.

3.Bear type. Bears generally like to go with the flow, wander around, hunt everywhere, and sleep well. This type is suitable for fun-loving and outgoing people. They are active during the day and have a high urge to sleep.

4.Wolf type. Wolves generally hunt at night, so this type is suitable for people who love nightlife and are creative. They are extroverted and have a moderate urge to sleep.

After understanding and judging your own type, I believe the following content will help you

How much sleep is enough? I'm asked this question at least five times a day. The answer is:

It depends. Babies need to sleep 12 to 18 hours a day. Toddlers need 11 to 13 hours of sleep.

School-age children need 10 to 12 hours of sleep. Eleven or twelve-year-olds need 10 to 11 hours of sleep. Teens need 8 to 10 hours of sleep.

In general, young adults in their early twenties stop growing and have a reduced need for sleep. The National Sleep** recommends that adults and seniors get up to 9 hours of sleep per night.

I've observed that focusing on numbers causes a lot of sleep disturbances, just as trying to reach your target weight can keep going through a vicious cycle of frustration and disappointment. The need for sleep is based on genetics. I talked about the sleep rush back in chapter 1.

Some people have genes that dictate that they need more sleep than others. Those with the long per3 gene are most vulnerable to the harms of sleep deprivation, including heart disease, stroke, diabetes, obesity, depression, and cognitive memory problems. You may have the short per3 gene, and six hours of sleep is enough.

You may have the long per3 gene and will be uncomfortable without seven or eight hours of sleep.

So, how many hours of sleep should we have? What is the prescribed number?

First of all, let me clarify ......

8 hours of misconceptions.

Everyone's sleep time is different.

8 hours of sleep is the best for people.

But not everyone's optimal sleep is 8 hours, and there are many reasons that affect the amount of sleep, such as: fatigue, weather, physical condition, etc.

It is recommended that every normal person sleep every day is guaranteed to be 8 hours, and failure to reach this level is a harm to the human body, which can affect the function of various organs.

Children have to sleep for more than ten hours, but five or six hours for the elderly is enough.

Scientists say it's eight! Personally, I think ten!

Minor. Newborn. Newborns do not yet have a relatively constant biological clock, and it is difficult to distinguish between day and night.

The recommended daily sleep duration is: 16-17 hours of sleep per day for 1-week-old newborns; 1-4 months, 14-16 hours of sleep per day. Newborns should not sleep less than 11 hours a day, otherwise normal development will be affected.

Infant. Babies sleep longer than newborns. In general, babies aged 5-12 months sleep 12-16 hours a day. At this time, parents should help their children maintain regular naps and sleep no less than 10 hours a day, otherwise normal development will be affected.

Toddlers and preschoolers. At this stage, children are more active and sleep is more important for their development. For children aged 1-2 years, the recommended sleep time is 12-14 hours per day; 3-5 years old, 11-13 hours of sleep per day is recommended.

Schoolchildren. After children enter primary school, only adequate sleep can ensure the efficiency of activities and learning in the day. Therefore, it is recommended that children aged 6-12 years old ensure 9-12 hours of sleep every day, not less than 8 hours, otherwise it will seriously affect learning efficiency.

Juvenile. At this stage, children are still in the period of growth and development, and the pressure of learning gradually increases, and the sleep time is relatively reduced. Children aged 13-17 should sleep for 8-10 hours a day, less than 7 hours, and will lose concentration and exercise, which will seriously affect learning efficiency.

1] Adults. Age group.

Sleep time.

Older teenagers aged 18-25 years.

26-70 years old.

7-8 hours (but the study found that it should not be less than 9 hours).

71-99 years old.

Over 100 years old.

hours (some experts believe that the elderly should also sleep more than 9 hours).

Assuming age x, the optimal sleep time y approximately satisfies y=21-6x. However, some experts have suggested that the elderly need longer sleep than adults due to their weak qi and blood, so they have y=22-7x. In this function, people over the age of 65 have an increasing trend in sleep time.

Longevity research. The six-year experiment was conducted by the University of California, San Diego School of Pharmacy and the American Cancer Society. They observed a million subjects between the ages of 30 and 102.

Sleep time refers to a natural physiological phenomenon of humans and animals, consciousness is natural, usually regular temporary suspension, during which the process time of physical recovery can reach the time of closing the eyes and resting, and the cerebral cortex is in a state of rest. The best time to sleep for adults is between 10 p.m. and 6 a.m.

Sleep time can be divided into intermittent sleep and continuous sleep, and the sleep time referred to in general life refers to the total sleep time in a day, that is, the sum of all the time in the sleep state. The body's biological clock recommends going to bed before 10 p.m. and waking up before 7 a.m. Go to bed early and wake up early to enhance immunity, which is conducive to fighting the invasion of viruses and thus improving work efficiency.
