How long to sleep is the healthiest time to sleep, and how long to sleep is the healthiest time to s

17 hours for newborns and at least 9 hours for elementary school students.

Of all health indicators, sleep duration and *** bad accounted for a large percentage. The latest issue of Taiwan's "Health Magazine" pointed out that different groups of people need different amounts of sleep.

Newborns within 1-2 weeks of age. The average total amount of sleep in a day (including night and day breaks) should be 17 hours. During this period, the quality of newborn sleep has a great relationship with the development and maturity of newborns, and many newborns also have a very high rate of dreaming, which may account for 40%-50% of the night's sleep.

Babies after 6 months of age. At this time, the average amount of sleep a day drops to 13-14 hours. At this stage, it is advisable for parents to ensure that their children maintain a wakefulness interval of at least two hours after the last sleep to ensure a good night's sleep.

Preschoolers. The total amount of sleep throughout the day is reduced to about 12 hours. At this time, your child will usually take a nap during the day, and this small amount of sleep is very important for preschoolers to help them develop and grow.

After entering elementary school. The total amount of sleep in a day will be reduced to 9-11 hours.

Adolescents entering puberty. During this period, the sleep pattern is similar to that of adults, and it is recommended that secondary school students sleep a total of 7-8 hours a day.

Adult. Ideally, 7-8 hours. However, according to statistics, people now have a serious lack of sleep time, and it is recommended to rest at least 10-15 minutes at noon every day to ensure a good mental state.

Middle-aged and older people. Sleepiness during the day and shorter sleep duration at night. In other words, it is not because the need for sleep has decreased, but because their ability to maintain a long night's sleep has deteriorated.

Studies have shown that middle-aged and elderly people sleep an average of 6 hours a night, and the dreaming stage accounts for about 20%.

Wu Jiashuo, a clinical psychologist at the Sleep Center of Taiwan Chang Gung Hospital, pointed out that when you find a sleep time that suits you, you can have good physical strength during the day and a good sleep at night. Therefore, instead of worrying about how many hours of sleep you need to be healthy, it is better to take some time to observe whether you are in good spirits, emotions and other aspects during the day, and whether you are satisfied with the quality of sleep. If you feel comfortable during the day and at night, you have slept well.

If you open a so-called popular science and health content about sleep time, you will find that many of the content is the same and overemphasizes the 8-hour sleep time theory.

Because of this, we have formed a unique and inherent sleep thinking that belongs to the Chinese, believing that only if you must sleep enough for 8 hours can you meet the sleep needs of the human body.

In fact, the so-called sleep time refers to a natural physiological phenomenon in humans and animals, and consciousness is natural and usually a regular temporary suspension. During sleep, physical strength can be effectively restored, and all organs can be fully rested.

Macro osmosis and sleep time is divided into tip and contact sleep, and the sleep time referred to in general life refers to the total sleep time in a day, that is, the sum of the time of all sleep states. However, the sleep time that we emphasize on a daily basis is actually nighttime sleep.

In the process of sleep, people seem to fall asleep all the time, but in fact, people have a sleep cycle, which is a biological rhythm of sleep, which includes two stages: non-REM period and REM period, and the two alternate for a sleep cycle. There are 4-5 sleep cycles per night, and each cycle is about 90-110 minutes.

So the question is, how much sleep is a day, and how many hours of sleep is the best?

First of all, how much sleep a person needs is mainly determined by age. After countless years of evolution and development, human beings have formed a constant biological clock in their bodies, that is, the sunrise and the sunrise are the daily income and rest.

However, newborns, infants, toddlers and preschoolers usually sleep for a relatively long time, especially newborns sleep about 14-16 hours a day. After that, as the body gradually matures, the biological clock will be formed.

In adulthood, adults need about 7-9 hours of sleep per day. However, this is not completely fixed, because everyone's living environment, physical and mental exertion, and physical needs are different, so the specific amount of sleep required is also different. 7-9 hours, 6-8 hours is just a data range.

As people get older, the amount of sleep they need will decrease. In particular, middle-aged and elderly people over 50 years old will need a significant reduction in sleep time when physical activity decreases, mental work decreases, and various organs of the body age. From a scientific point of view, 5-7 hours of sleep is enough to meet the needs of seniors over 50 years old throughout the day.

It should be emphasized here that sleep time is not a complete criterion for judging whether a person sleeps well, and we also need to observe the state after waking up.

If you wake up, you feel clear-headed, light-headed, and have sufficient physical strength and energy, then even if you only sleep for 5 hours, your body's needs have been met. On the other hand, if you wake up feeling physically and mentally exhausted and tired, this is a sign of poor sleep quality.

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. For example, infants and young children sleep for a long time, often needing about 16 hours of sleep; For example, primary school students also sleep for a long time, and they should ensure eight to nine hours of sufficient sleep time every day; And it's best to take a lunch break at noon; If you are an elderly person, you may need to sleep for about six hours.

Of course, the specific situation should be analyzed for specific individuals, if the sleep time is not very long, but the person feels very comfortable, without any fatigue, it can also be mainly based on self-feeling, adjusting the sleep state can indeed prolong life.

Hello, happy to answer for you!

The answer is no. Traditional Chinese medicine believes that lying down for a long time hurts qi, that is, too much sleep dissipates the essence and energy, and makes the yang energy and spirit slack. Modern research has proved that excessive sleep and bed rest can cause neurological depression of cerebral cortex cells, resulting in cerebral hypoxia.

Therefore, sleeping more is not good for your health.

So, how long is the right amount of sleep? The amount of sleep you spend varies from person to person, and there is no absolute value. It is generally accepted that 8 hours of sleep is normal.

In a survey of 1 million people, 80% of adults slept 7 to 9 hours a day. Another survey of 800 people found that the average sleep time was hours. In addition, the so-called short sleepers who slept for 4 to 5 hours and the long sleepers who slept for 10 to 11 hours accounted for only 1% of 2%, while the ultra-short sleepers who slept less than 4 hours and the ultra-long sleepers who slept more than 11 hours accounted for less than 1%.

In short, the duration of sleep varies from person to person, and the average person generally does it within the range of 6 to 9 hours.

Hope it helps!

Sleep is one of the most basic needs of the human body, and it is essential for health and physical condition. Insufficient sleep can lead to adverse effects such as physical exhaustion, headaches, and difficulty concentrating. Therefore, we need to get enough sleep to maintain a healthy lifestyle.

So, how long does it take to sleep to maintain good health? It is generally accepted that an adult needs 7-8 hours of sleep per day to stay healthy. This time may vary from person to person, and age and gender will also affect this time.

However, 7-8 hours is only a rough estimate, and the specific value depends on the individual's situation. First of all, you need to consider whether your body needs extra rest time, such as physical work or long mental work. If that's the case, you'll need extra sleep to recuperate.

Secondly, you need to consider your own physiological situation, such as whether you have sleep disorders or other health problems. If you have health problems that require more sleep time, then you need extra sleep time.

Overall, how long you sleep to stay healthy depends on the individual's physical and physiological condition. Everyone needs adequate sleep to stay healthy, but the exact amount of sleep may vary from person to person. If you're feeling exhausted, it may be helpful to increase your sleep time.

If you don't feel this way, then you may only need to sleep for 7-8 hours to maintain good health.

Sleep is not the longer you sleep, the better you sleep. Generally, normal adults can sleep about 7-8 hours a day to ensure normal sleep.

If the sleep time is too long, it is not conducive to the health of the body, and the sleep time makes the mountain too late and slippery, which will cause some symptoms of dizziness and discomfort in the mind, which will affect the study and work status during the day, and for a long time, it is easy to lead to biological clock disorders and poor sleep at night.

Therefore, it is better to go to bed early and wake up early, have a regular schedule, go to bed before 22:30, and wake up before 7:00.

Usually you can take a lunch break at noon, 30-60 minutes is fine, and you don't need to sleep for 2-3 hours.

Generally speaking, sleep time of 6 to 8 hours is the best, in addition to the elderly and children, adults sleep for 6 to 8 hours, are OK, there are individual groups, sleep four or five or five or six hours a day can also ensure that the working condition is very good, these are normal sleep, sleep less than six hours In general, sleep time of 6 to 8 hours is the best, in addition to judging the dust and children, the sleep time of adults is generally 6 to 8 hours, which can be missingThere are also some people who can sleep four or five or six hours a day to ensure that they are in good working condition, which are all normal sleep.

People need different amounts of sleep at different ages. The right sleep time and good sleep quality are the reasons for good health. In some special cases, some people sleep longer, such as the famous scientist Albert Einstein, who sleeps about 10 hours a day.

Some people get very little sleep, such as *** Prime Minister, who only sleeps 4 to 5 hours a day. But they all made remarkable achievements.

Newborns need more than 20 hours of sleep a day. By about one year of age, about 15 hours of sleep per day are required, and from one year to 18 years old, the amount of sleep required per day gradually decreases. By the age of 13 to 18, the need for sleep is about 9 hours a day.

Adults need about 7-8 hours of sleep per day. As people reach old age, the amount of sleep they need will increase again. 60 to 70 years old, it takes about 9 hours.

70 90 years old, it takes about 10 hours. People over the age of 90 need more than 10 hours of sleep a day.

It is usually seven hours of sleep every day, which is relatively healthy, but because of different personal conditions and physical fitness, everyone's sleep time is also different, some people's sleep time is relatively short, usually seven hours of rest can meet the body's needs for sleep, but young people are best to meet eight hours of sleep time, the general work and rest is from 22 o'clock to six o'clock is more suitable for the human body's sleep time, and the reasonable sleep time is also good for their own health, It helps the liver to produce blood better, if you feel that you don't get enough sleep, you should rest more, try to avoid staying up late, and keep your work and rest habits regular.

I think it's about nine hours.
