Sleeping eight hours a day is a luxury, but what is the scientific sleep time?

I think we need to choose the sleep style that suits us, and I also think that there is no fixed time requirement for scientific sleep time, but we need to ensure our sleep quality.

Humans spend 1 3 hours of their time sleeping, especially people who sleep less than 8 hours a day, and even if they sleep enough for 8 hours, they will feel tired. For most people, getting enough 8 hours of sleep a day is already a luxury. This is because when we fall asleep, the body is in a state of dormancy, relaxation, and even inhibition.

On the one hand, this can promote our metabolism, delay aging, improve immunity, and on the other hand, it can make people more energetic and more efficient. <>

We need to ensure that we sleep well.

Since the length of sleep has a great impact on our physical health, for people who have the habit of sleeping enough for 8 hours, both sleep quality and sleep time have reached a very ideal state. However, when we sleep less than 8 hours, it will cause certain damage to our body, so we need to take the initiative to ensure our sleep quality, so that our body can get enough rest and recovery. <>

We also need to pay attention to our sleep status.

No matter how short your sleep is, you should fall asleep from now on. At the same time, at this stage, our body produces a type called melatonin, which has a very important role in regulating the wakefulness and fatigue of the human brain. So, when you fall asleep, you will slowly fall asleep and stay asleep until 2 a.m.

During this time, if you can maintain a good quality of sleep without getting too tired, it will be enough to meet our needs. <>

Finally, we need to develop a regular sleep habit and don't let ourselves sleep late or early in the morning. If you feel that you don't get enough sleep, then you should make up for it in time. And you should make sure that you get 7 or 8 hours of sleep every day.

The scientific sleep time is 8 hours, and you have to fall asleep after 10:30 every night, and more than 10:30 is a late night.

Scientific sleep time is to ensure that you have a good mental state and your body can get enough rest.

The scientific sleep time is that adults should sleep more than seven hours a day, and my current sleep time is up to the standard, and I can sleep up to 9 to 10 hours a day.

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.

Everyone's sleep needs and habits are different. While some people do need 8 hours of sleep to feel energized, there are also many people who feel tired even when they get enough sleep.

This may be due to poor sleep quality, such as sleep disturbances, disturbances in sleep, etc. Common sleep disorders include sleep apnea syndrome, insomnia, increased pressure in the arteries during sleep, and more. When the body does not get adequate and deep sleep, the body can feel exhausted even if it has enough sleep.

In addition, the feeling of fatigue in the body may also be related to the sleep cycle. The sleep cycle consists of two states: rapid eye movement (REM) and non-rapid eye movement (NREM).

REM is present during the deepest part of sleep, when the person is in a dream state, whereas NREM is considered to be the deeper period of sleep. If you wake up during NREM, your body will still feel tired even after 8 hours of sleep.

There is also a common questionSome people may have the root cause of physical fatigue in their daily lives, such as lack of exercise, overwork, eating problems, and more. These problems can have a negative impact on physical fatigue.

Therefore, it is recommended that you pay attention not only to the time you sleep, but also to the quality of your sleep. At the same time, it is also important to maintain a healthy lifestyleThis includes adequate exercise, a sensible diet, and a regular lifestyleThese measures can help improve sleep quality and relieve fatigue in the body.

It is definitely true that you must have enough sleep so that you can strengthen your body's immune system and avoid a decrease in immunity.

This statement is correct, because only *** 8 hours of sleep, our body resistance will be strong, immunity will be strong, physical fitness will be good, if less than 8 hours, it may have a certain impact on our body.

Actually, it's not quite true, even 6 hours can keep you in better shape. It also depends on the person's constitution.

I don't think so. Some people are in a better state of mind and don't need to sleep for 8 hours at all.

I don't think 8 hours is enough, I have to get 10 hours of sleep.

Not necessarily, because some people are old or children, their sleep time is different, and it is not suitable for everyone.

No, if you are a baby or a teenager, they will need more sleep, and not everyone is suitable for this time.

It is a normal sleep, everyone will sleep for 8 hours, and this sleep is just right for the human body.

Not all people are suitable for eight hours of sleep a day, for example, some elderly people, maybe they can't sleep for eight hours at all, followed by some children's sleep to be about 9 or 10 hours is normal.

It still has to be divided into different situations. Everyone's needs are different, so the length of sleep is also different. It is not possible to generalize.

I don't think so, because children need a lot of sleep to ensure that they are in good health and healthy.
