How many hours do you think a normal sleep should be?

Sleep is the most important way for people to rest, normal people need 8-10 hours of sleep every day, but children can be appropriately extended, especially newborns sleep up to 10 hours a day, the elderly will sleep less, but not less than 5 hours.

Personally, I feel that sleeping is generally correct to meet the normal 8 hours of sleep. If you can't guarantee such a long time, then your spirits won't be too good during the day! Another thing is to go to bed as early as possible, it is best to start going to bed at 10 o'clock at night, no more than 11 o'clock at the latest, and sleep until 6 or 7 o'clock in the morning.

If you sleep too late, you won't be in a good mood the next day.

Generally speaking, the normal time is about 8 hours. From 10 p.m. to 7 a.m. the next morning, this is still a reasonable time arrangement according to your own situation.

I think that if you are a child, you should have nine hours of sleep, but for a young person in your 30s, I think seven hours is enough, and if you sleep for too long, you will not be refreshed.

I think the normal sleep time should be eight hours, eight hours, enough to nourish the spirit.

Sleep in moderation. One of our key points is that you can't sleep less.

In many books, it is said that adults generally sleep 7 to 8 hours a day. However, Dr. James Maas, a professor of psychology in the United States, recently pointed out that 6 to 7 hours of sleep at night is not enough for a person.

The results of his sleep studies show that only 8 hours of sleep can bring the body to its peak function. So what is "in moderation" is mainly "mental and physical recovery" as a criterion.

I remember that a scientist in the UK said that the normal sleep of the human body should be controlled within eight hours, and death will be accelerated if it exceeds eight hours, and I don't know if there is any scientific basis, but I have read this article, I remember it for a long time, and I don't know if I can find it, but what we already know is that from 23 o'clock to 1 o'clock in the morning, the human body is a deep sleep, and from 1 o'clock to 3 o'clock it is a deep sleep, but it is still recommended not to stay up late, go to bed early and get up early.

This varies from person to person. Some of them were also very energetic for five or six hours. Some take seven or eight hours. In short, it is recommended that you sleep no more than 9 hours a day.

Babies sleep for more than 10 hours. Children's sleep is more than eight hours. Adults sleep more than six hours.

Usually 6-8 hours, if it is less than 6 hours, I will feel very uncomfortable, and the next day I will not be in a good state. But sleeping too much is not good, on the contrary, it will cause headaches. All 6-8 hours is relatively appropriate.

Eight hours is optimal, but it's hard for young people nowadays to get enough sleep.

<>1. In fact, the best time to sleep is probably 7-8 hours. Not really. For most people, this time can be counted as an average time, but it is not suitable for people who sleep for a short period of time.

You may have both of these people around you. One of them doesn't sleep much every day, but is still in good spirits, while the other needs a long sleep time, otherwise it is difficult to get rid of fatigue. Human sleep has deep sleep and light sleep, and the cycle is hours.

2. The brain is at rest during deep sleep, while dreaming is during light sleep. Deep sleep is divided into four phases that gradually deepen. After the peak of sleep, it gradually becomes lighter.

This cycle is hours, and finally returns to a state of light sleep. To stay awake, it's best to wake up during light sleep hours. If you wake up in a deep sleep, your brain will wake up when it's resting, so even if you wake up, you will feel groggy and it will take a long time for your brain to wake up.

That's why we sometimes want to sleep more and more.

3. The harm of excessive sleep, increasing the probability of depressionRelated studies have found that long sleep time will increase the probability of depression. If you only sleep seven to nine hours a night, the relative probability of depression is lower. Once this time is exceeded, the probability of depression can be more than double that of seven to nine hours.

Damage to the brain, if you sleep too much, can cause damage to your brain in the long run, causing your brain to function as a decline. There are also studies that have found that sleeping brains outside the normal range will age two years above the normal range.

4. To make up for the lack of sleep, take a nap for 15-30 minutes at noon. This also follows the sleep cycle, most importantly getting up during the early light sleep period. Even if it's just for a short time, the body can rest and the brain will become clear.

However, more than 30 minutes is not acceptable. The deeper you sleep, the less likely you are to wake up, which is counterproductive. It's also good to have some coffee before bed.

The effects of caffeine will be visible 30 minutes after drinking coffee, so take a half-hour nap after drinking coffee to get up.

I think 8 hours is the best choice, these 8 hours can make the body well, recover, and not easy to make people dizzy.

It is best to take about 7 hours for adults, and about 10 hours for children.

A normal person should maintain about eight hours of sleep a day. Lack of sleep can lead to a lack of energy, and excessive sleep can also lead to a worse complexion.

A normal person should sleep for 6-8 hours. Everyone has to get a good night's sleep after a busy day. Sleeping is a physiological response, part of the brain's neural activity, and the result of inhibition after nerve cells in the cerebral cortex continue to be excited.

When the inhibitory effect is dominant in the cerebral cortex, the person sleeps.

In life, people have work and rest; In neural activity, there is excitation, and there is inhibition. Inhibition is done to protect nerve cells so that they can be re-excited and people continue to work. Children must sleep for 11 hours per day, 10 hours for elementary school students, 8 hours for junior high school students, and 7 hours for high school students.

1. Newborns from birth to 3 months old should sleep for 14 to 17 hours.

12 to 15 hours for infants from months to 11 months.

11 to 14 hours for toddlers up to 2 years old.

For children up to 5 years old, 10 to 13 hours is recommended.

9 to 11 hours for school-age children up to 13 years old, and 8 to 10 hours for adolescents aged 14 to 17 years.

The age group for young adults up to 25 years old, although 7 to 9 hours is recommended for both them and adults between 26 and 64 years old.

For those over the age of age, it is recommended to sleep for 7 to 8 hours.

Sleep occupies one-third of a person's life, so sleep is very important for people!

When people sleep, all physiological functions such as metabolism are reduced, and the human body is in a protective inhibition state, avoiding excessive consumption of nerve cells, and also helping the human nervous system to restore normal function.

During sleep, the body's anabolism is greater than catabolism, so when you wake up when you get enough sleep, you can feel energetic.

Sleep is necessary to maintain the body's immune function, and if a person does not get enough sleep at night, the number of immune system cells and activity will decrease.

Good sleep is especially important for babies, growth hormone is very important in the development and growth of children, and the human body secretes the most growth hormone in the first half of the night.

Having a good night's sleep is the guarantee of labor efficiency and the maintenance of human health!

The length of sleep is different from that of people at all ages, babies are generally about 15 hours, preschool children need 12 hours of sleep, primary school students need about 10 hours, young adults maintain 7-8 hours, and the elderly keep about 9 hours.

What is the best sleep time for a person, the survey results show that 7-8 hours of sleep per night is the best, those who sleep less than 6 hours are prone to diabetes and obesity, if they do not get enough sleep, vascular disease is twice as high as that of people who sleep well, and the mortality rate of people who sleep for more than 9 hours is also relatively high, and too much sleep is also easy to cause some health problems!!

Normal people sleep 6-8 hours, children sleep 10 hours, and babies sleep more.

Staying up late for a long time, even if you sleep for 8 hours, you will be prone to endocrine disorders in a few years, and the biological clock will be messed up.

It is best for children to go to bed around 20:30 at night, because the body grows, and the development of various organs is at its peak from 10:00 to 11:00, and it must be completed under deep sleep.

Teenagers should go to bed before 10 p.m. to help with their learning status for the next day.

Adults should pay attention to the normal sleep time before 11 o'clock, usually maintain at least seven hours of sleep time, pay attention not to stay up late, and have a regular schedule.

It is often said that it is best to get enough sleep for eight hours a day.

But that's not the case, according to the report:

In general, it is mainly the quality of sleep that is related to age. ：

Ages 14-25: 8 hours Age 26-40: 7 hours Age 40-58: 6 hours Over 58: 5 hours – 6 hours.

In fact, there are some young people who only need to sleep for a few hours a day, and even if they sleep for a few hours, they can maintain sufficient energy, so it may vary from person to person.

Finally, I would like to add that too much sleep is bad for your body. For example, it induces diabetes, weight gain, memory loss, and increases mortality.

Regarding the normal sleep time, the more popular saying on the Internet is 8 hours, or 6 to 8 hours, but in fact, there are certain individual differences in sleep time, some people sleep four or five hours a night and wake up the next day are still energetic, while some people sleep for 8 hours but are not awake.

Therefore, it can only be said that most people's sleep time is between 6-8 hours, if their sleep is less than this time or more than this time, as long as it does not affect the mental state and work efficiency, it is counted as normal sleep time.

Even the same person may have different sleep durations at different ages. Babies and toddlers need up to 17 hours of sleep, and in childhood they need more than 10 hours of sleep, and the amount of sleep they need gradually decreases as they age. Although the elderly sleep less at night, they sleep more during the day, and the total sleep time is not much less.

In short, as long as it does not affect energy and life, it is acceptable for there to be individual differences in sleep time.

Newborn 20-22 hours 2 months Infant 18-20 hours 1 year old 15 hours 2 years old 14 hours 3-4 years old 13 hours 5-7 years old 12 hours 8-12 years old 10 hours 12-18 years old 9 hours Adults 7-8 hours (not less than 6 hours) 60-70 years old 9 hours 70-90 years old 10 hours Over 90 years old It should not be less than 10 hours.

1.Normal people sleep for 6-8 hours (10 hours for the elderly and children, and longer for infants).

2.Beauty sleep hours are 22 o'clock - 2 o'clock in the morning.

3....... staying up late for a long timeEven if you sleep for 8 hours, you will be prone to endocrine disorders in a few years, and the biological clock will be messed up.

4.It is best for children to go to bed before 20:30 at night, because they are long.

5.Teenagers should go to bed around 10 p.m.

6.As for beauty lovers, be sure to sleep before 2 a.m., because ** metabolism before 2 a.m.

7.For the elderly, it is better to sleep between 21-22 o'clock in the evening.

It is important to get a normal amount of sleep every day, and the average adult should be 6-9 hours. For example, going to bed at 10-11 o'clock at night and getting up at 6-7 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, 4-10 hours is in the normal range, mainly after waking up the next day. In fact, various groups of people have different sleep requirements.

Generally speaking, people aged 10-18 need 8 hours of sleep per day, people aged 18-50 need 7 hours of sleep per day, and people aged 50-70 need 5-6 hours of sleep per 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.
