How long does a normal person sleep?

The average normal adult sleeps about 6-8 hours.

The normal sleep time of people is 7 9 hours, children and babies can sleep more time, and the middle-aged and elderly people can maintain 7 hours of high-quality sleep is enough to provide a day's mental energy.

Why do people sleep? It is to fully relax the body, eliminate and self-repair all kinds of unsuitable cells in the body, make the human body as full of vitality as machine parts, and ensure that the next day's energy is accurate. The purpose and benefits of sleep are many:

1. Eliminating fatigue and restoring physical strength are the main functions of sleeping. The gastrointestinal tract and its related organs synthesize and produce energy substances required by the body during sleep. Body temperature and blood pressure decrease, and basal metabolic rate decreases, so that physical strength can be restored.

2. Sleep re-characterizes the memory of reading and writing and all the information received during the day, keeping the mind rejuvenated.

3. Sleep enhances the body's ability to produce antibodies and improve resistance. Sleep makes tissues and organs recover faster on their own.

Normal adults sleep 7-8 hours at night, teenagers need 9-10 hours, children need about 12 hours, and infants need more than 14 hours of sleep.

Adults don't need exactly the same amount of sleep, and a small number of people only sleep 4-5 hours at night, and such people are called short sleepers. Although the sleep time is short, the deep sleep period is similar to that of normal people, that is to say, although the sleep time is less, it is the light sleep and dreaming period that is reduced, and the deep sleep period, which is the most important for energy and physical recovery, is enough. So such a person will not feel tired the next day, or not sleep well.

There are also long sleep needs, which may require 9-10 hours of sleep at night, or even more than 10 hours. Therefore, for sleep, the sleep time is not always certain, and the main purpose of sleep is to have sufficient energy for work and life the next day. If you feel refreshed the next day, it means that you have enough sleep the night before, and you don't have to worry about how long you have to sleep.

How long should a normal person sleep?

A normal adult's normal sleep time is about 6-8 hours a day, but in fact, whether each person's sleep time is sufficient mainly depends on whether a person is energetic the next day, whether there are symptoms such as sleepiness, dizziness, dizziness, fatigue, and memory loss.

If an adult sleeps less than 6 hours a day, but is still able to maintain full energy the next day without any of the above symptoms, it is normal for an adult to sleep less than 6 hours. If an adult sleeps more than 8 hours a day, but still feels uncomfortable, drowsy, memory loss, energy loss and other symptoms the next day, 8 hours of sleep is not enough for him.

If you don't get enough sleep for a long time, it will not only affect people's spirits, but also lead to disorders of various organ functions, including increased blood pressure, abnormal blood sugar, heart and lung functions, as well as cerebrovascular lesions, which may be related to sleep deprivation.

In the case of children, a longer amount of sleep is required, and infants and toddlers are required to have at least 15-18 hours of sleep.

If there is a long-term lack of sleep time and sleep disorders, you should consider using sleep aids**, whether it is difficulty falling asleep or the sleep duration is short, you can use sleep aids to help**.

Therefore, the probability of a person's normal sleep time is 6-8 hours, but it mainly depends on whether there are symptoms such as sleepiness and lack of energy on the next day to judge whether the sleep time is sufficient.

This varies from person to person depending on the age group and the individual's constitution. That is to say, people of different ages, different individuals, and different states have different physiological requirements for sleep, and even obvious differences.

In the case of adults, for example, a normal adult should sleep 6 to 8 hours a day. In the case of teenagers, children will ask for more sleep. Babies and toddlers sleep longer, ranging from 15 to 20 hours.

If an adult sleeps less than six hours a day, but is still able to maintain full energy the next day without any discomfort, such as: drowsiness, dizziness, dizziness, fatigue, memory loss and other symptoms, then less than six hours of sleep is enough for him. And if an adult sleeps more than eight hours a day, but still feels unwell the next day, then eight hours of sleep is not enough for him.

It can be said that judging whether a person's sleep time is sufficient, mainly to see whether he is energetic the next day, whether he has various symptoms such as drowsiness, dizziness, dizziness, fatigue, and memory loss.

If you don't get enough sleep for a long time, it will not only affect your spirit, but also cause dysfunction of various organs in the body, including increased blood pressure, abnormal blood sugar, and affected heart and lung functions. In addition, cerebrovascular lesions may be related to sleep deprivation.

Therefore, if you have a lack of sleep time for a long time, or sleep disorders, you should go to the doctor, and under the guidance of a doctor, use sleep aids and carry out **. Don't stay up late, and certainly don't be overly nervous.

Everyone's sleep time is not bad, there are certain differences, mainly determined by sleep quality.

Usually it is between 7 and 9 hours.

First of all, sleep is needed for life, and sleep helps relieve brain fatigue. A normal person must sleep more than eight hours a day to ensure a normal sleep quality for a day.

Adults need a slightly different amount of optimal sleep per day depending on their age

18-65 years old: Approximately 7-8 hours of sleep per day, some people may need 9-10 hours, and at least 6 hours.

Over 65 years old: Most people need 7-8 hours a day, and some people may only need 5-6 hours.

Therefore, for people of different ages, the daily sleep time required is generally shortened with age, and sometimes it varies due to individual differences, as long as the sleep time can meet the needs of daily work and life, it is suitable.

The average amount of sleep for a normal adult is 6-8 hours, but it is not absolute, it varies from person to person and varies from person to person. In addition to the amount of sleep, the quality of sleep is also very important. Some people who sleep *** can sleep for five hours to meet their sleep needs, while some people sleep for eight hours still have a feeling of not getting enough sleep, and still can't meet the needs of work and study the next day.

Normal people's sleep is divided into light sleep and deep sleep, and only enough deep sleep can allow the brain and body to be fully rested and adjusted. People with high sleep quality sleep are more deep, and only more than five hours of sleep can meet the needs of the next day's work and life, and they are still full of energy. Some people have more light sleep, are always dreaming, sleep is lighter, and wake up easily, which requires sleep time to make up for the lack of sleep quality.

If there is no daytime sleepiness the next day, whether it is more than five hours of sleep or more than eight hours, it is appropriate for the individual.

Generally, adults can maintain a sleep time of about 8 hours, but there is no mandatory requirement for sleep time every day, and it is generally based on their own situation. As long as you are in a good state of mind the next day, you will get enough sleep according to your needs.

People of all ages need different amounts of sleep. Generally, newborns sleep for about 18 hours; Babies are about 12 hours; Preschoolers sleep for about 10 hours; Adolescents sleep for 8-9 hours; 7-8 hours for adults; Older people may have their sleep reduced to about 6 hours due to various functional declines.

People with sleep disorders can drink a glass of warm milk before going to bed, and do appropriate physical exercise during the day to help them fall asleep, improve sleep quality, and ensure that the brain is fully rested.

With enough sleep, nerve cells and memory cells are likely to play their best role. If you don't get enough sleep for a long time and have poor sleep quality, it is easy to cause various health problems, such as mental weakness, sleepiness, malnutrition, etc. Therefore, in order to ensure good health and maintain high efficiency in daily work and study, adequate sleep time should be ensured.

Sleep is an indispensable and important part of human life, and about 1 3 of a person's life is spent in sleep.

Primary school students should be guaranteed 10 hours of sleep per day and secondary school students 9 hours a day. Children and adolescents are in an important stage of growth and development, and adequate sleep is very needed, which can not only eliminate fatigue and restore physical strength, but also promote normal growth and development. Lack of sleep can make it difficult for students to concentrate, have memory loss, affect brain development, and even cause serious physical and mental illnesses.

On the one hand, the cause of sleep deprivation in children is due to the heavy learning burden of children, especially in urban areas, parents have higher expectations for their children, so that children attend various cram schools, tutoring classes, on the other hand, it may also be related to children watching TV or participating in other entertainment activities at night. Children should be trained to develop a healthy lifestyle of regular work and rest to promote their healthy growth.

The problem of insufficient sleep time and excessive sleep time among adults in China exists at the same time. Studies have found that insufficient and excessive sleep time increases the risk of impaired glucose tolerance and diabetes, and is also an important factor in the increase in cardiovascular disease and all-cause mortality.

The elderly are also a key group of people who do not get enough sleep time, which may be related to the higher incidence of difficulty falling asleep and early awakening in the elderly. Because the metabolism of the elderly slows down and physical activity decreases, the need for sleep time can be less, generally 5 7 hours, some studies believe that the sleep time of the elderly can not be reduced, and with the increase of age 60 70 years old elderly sleep time should increase to about 8 hours, 70 90 years old people should sleep about 9 hours, 90 years old people, should sleep 10 12 hours a day. There is still very little data on sleep duration and disease and mortality in China, and further research is needed.

Individual time is self-employed, and varies according to the length of time of different people. For example, eight hours is enough, and some are long sleeps, and ten hours of sleep a day are enough. Take Albert Einstein, for example.

Some have short sleeps, sleeping four or five hours a day, such as ***, he just sleeps four hours is enough. So the average sleep time is about eight hours, some are eight to ten hours, but I think sleep must be based on your own situation, you need a few hours of sleep is appropriate for you. It's usually about eight hours to ten hours, some people try ten hours, some people say six hours is enough, six hours I have a clear mind, very energetic, it doesn't affect my state, it's been like this for decades, then your sleep is reasonable.

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.

It is about seven hours for adults and 22 hours for newborn babies.

The amount of sleep required per day varies greatly from person to person, with an average of about 8 hours, some people may need 4 to 5 hours to suffice, and about 10% of healthy people fall into this condition. 15% slept more than 8 hours or more. In different stages of a person's life, the sleep time is not the same, the newborn baby needs to sleep more than 16 hours a day, with the passage of time, the child grows up, the sleep time gradually decreases, the youth takes about 8 hours, which is relatively longer than that of adults; In adulthood, each person stabilizes on their particular sleeping habits; Generally, after entering the old age, the sleep time gradually decreases, such as if the adult or the elderly sleep more than 10 hours or less than 4 hours, then it should be considered whether there is something wrong with the person, and the hospital needs to be examined.

In addition, the required sleep time will increase or decrease due to changes in physiological state of the same person at different times. For example, women may sleep more during menstruation, and pregnant women often need more than 10 hours of sleep a day. Sleep is generally prolonged after heavy physical work or physical activity, while excessive mental work often results in less sleep.

Therefore, it is impossible to generalize about how much sleep people need.

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

2. The time of beauty sleep is 22 o'clock - 2 o'clock in the morning.

3. 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.

4. It is best for children to go to bed before 20:30 at night, because of the long body.

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

6. As for beauty lovers, they must go to bed before 2 a.m., because ** metabolism before 2 a.m.

7. The elderly should sleep between 21 and 22 o'clock at night. Therefore, people's sleep time should not be too long, 7 to 8 hours of day and night for adults is enough, if you want to increase sleep time to get healthy, it will be counterproductive and increase diseases.

In general, 6 to 8 hours of normal sleep a day is enough. If you miss sleep due to work or other things, you can make up for it appropriately depending on the amount of delay, and the total amount of compensation should not exceed two hours.
