How much sleep is appropriate?

7 hours of sleep is sufficient, feel not so energetic and have some headaches, it is best to see a doctor.

When I was in high school, there were only about 6.

When you become an adult, 7 is enough.

There is no benefit to whoever has more.

Also remember that you must take a nap for 20 to 30 minutes at noon.

The afternoon was full of experiences.

Is it? I am a high school 2 student, and my classmates sleep 8 hours a day, but they are still quite sleepy every day. I've heard of Leonardo da Vinci's habit of sleeping for half an hour every few hours. Of course, he is not an ordinary person and has no comparison, but I still recommend taking a nap when you are sleepy.

Adults sleep 8 hours a day, and children aged 6-13 years sleep 8-10 hours appropriately. As we age, we get less sleepy, and many older people get enough sleep for 6 hours. Sleep time varies from person to person, so it's better to stay energized during the day.

In addition, the daily sleep time of adults varies greatly due to work and lifestyle habits, which fluctuates around 5-8 hours. While most people may get 7-8 hours of sleep, some people need 8-9 hours or more of sleep to feel sufficient, while others get comparatively less sleep and 4-5 hours of sleep feel sufficient. At this time, it should be judged according to the situation of waking up the next day, if you feel full of energy after waking up, no longer sleepy, and can concentrate on your work and life during the day, it proves that your brain and body have been rested enough at night, and the sleep time of the previous night can meet your needs.

If you wake up with headaches, sore eyes, and low energy, it means that you haven't rested well. If you feel dizzy after thinking about it, although you are not sleepy but you are not motivated, it means that you have slept too much, and you can get up early appropriately.

From a health point of view, sleeping for four hours is not necessarily good for the body, it varies from person to person, the length of sleep of people, this is based on science, so for most people, sleeping for four hours is harmful to physical health, and the wisdom of the hour was certainly not perfect last year.

First, everyone's sleep time is different, some people sleep for a long time, some people sleep for a short time, as long as they wake up the next day is not dizzy, not there is nothing uncomfortable, as long as you feel that you have a special energy after getting up, you will say that you have slept well, whether it is four hours or six hours or eight hours, as long as you get up the next morning to be particularly energetic, it means that you have slept well.

Second, sleep is based on science, and it is generally accepted that the sleep time is generally eight hours, yes, this time has a certain scientific truth, not which person has the final say, so everyone is also recognized, if friendship Some people sleep for four hours are particularly spiritual, then he may have adapted to this time, but the most people are not necessarily suitable.

Third, sleep is also different, some people sleep and fall asleep soon after lying down, and some people may not be able to enter the sleep state after lying down for an hour, so the quality of sleep is not the same, some people are deep, it is also different, some people lie down and quickly enter the sleep state, and soon enter the deep sleep people, as long as they enter the deep sleep to have a good rest Deep sleep, good, sleep quality.

Fourth, sleep, four hours or six hours, or eight hours, this varies from person to person, this is not a unified standard, but most of the cognition is eight hours, as long as you have a deep sleep, you have rested, but your sleep quality is not good, you can't beat your sleep quality, it will be harmful to the body.

In short, four hours of sleep, or six hours, or eight hours? As long as you are used to it, as long as you wake up the next day, you are energetic and can go to work normally, it means that your sleep quality is already very good.

If you only occasionally sleep for four and a half hours at a time, it may not cause significant physical discomfort. However, this is a lack of sleep for a long time, which is a great loss to the human body. It is generally recommended to stay about eight hours of sleep, but the exact amount of sleep is also affected by age, and usually the amount of sleep required decreases as you get older.

1. Harm to sleep for four and a half hours for a long time can easily lead to physical exhaustion, poor mental state, fatigue, drowsiness, loss of concentration, memory loss and other uncomfortable symptoms, as well as irritability, irritability, anxiety and other negative psychological states, which not only affect daily work and life, but also accelerate the failure of various organs or tissues, which will seriously threaten physical health.

It depends on how well you sleep. High quality sleep, 5-6 hours should be no problem. If you have insomnia, dreams, and spend the whole night in tension, 10 hours are also in vain.

For those who practice the exercises, 2 hours of meditation may be enough for a day's rest, which is more energetic than the average person's 8 hours of sleep. 5-8 hours of high-quality sleep for young people is enough to ensure normal learning. The most scientific sleep time is 7 hours.

According to the research of experts, 7 hours of sleep is the most standard. It is also the most able to live a long life.

7 hours is better than 6 hours and certainly better than 8 hours. In this way, you can ensure the best state of study and work.

In general, 6-8 hours of sleep is optimal.

In addition to the elderly and children, adults generally sleep for 6-8 hours, and there are some groups of people who sleep 4-5 hours or 5-6 hours a day to ensure that they are in good working condition, which are normal sleep times. Sleep less than 6 hours or more than 9 hours is prone to hypertension, diabetes and other diseases, because lack and excess sleep may lead to sympathetic nervous system hyperfunction, endocrine and metabolic disorders, and the formation of inflammatory states that affect human health.

When it comes to how many hours of sleep is best for an individual, the doctor believes that the most appropriate amount of sleep depends on whether he or she can maintain his or her energy during the day. If you feel refreshed, energized, energized, and able to concentrate on certain things, your brain and body have been rested enough, and the sleep of the previous night is sufficient.

Try to make sure you fall asleep before 11-12 p.m. to help you feel more energetic the next day. At the same time, it is better to pay attention to the quality of sleep, and if you can take a lunch break, it is better to try to maintain a lunch break of about an hour. Avoid staying up late and develop a healthy lifestyle habit of going to bed early and waking up early.

6-8 hours.

However, there will also be some abnormalities, such as young people's sleep time is too short: young people may sleep late at night or like to stay up late, which is their own reason to shorten their sleep time and need to adjust their sleep habits.

Some people may have insomnia, which needs to be further investigated, and some may have psychological factors such as anxiety and depression, or shorten sleep time due to anxiety and depression, and need to be examined accordingly and judged by doctors;

Sleeping too long: In obese people, there may be signs of snoring at night, i.e., sleep apnea may be present at night. Although this group of people sleep for a long time, the quality of sleep is poor, and they will experience daytime sleepiness, sleepiness or excessive sleep, and may need to intervene for the corresponding problems,** to ensure a good sleep and help work and life.

How much sleep is appropriate for a person per day? The normal sleep time of a person every day is 6-8 hours of chain, generally speaking, the sleep time of people is constantly decreasing with age.

The sleep time is 18-20 hours in infancy, 10 hours in elementary school, 8-9 hours in middle school, and 6-8 hours in adulthood. It is generally recommended that 8 hours is better. However, generally the sleep time will be reduced after old age, and some elderly people can sleep for 5-6 hours.

There is another criterion for judging whether the sleep time is enough, which is to see whether the mental state of the next day is good. If it does not affect your study and work, your mood is relatively happy, even if you sleep less than 6-8 hours, it is still normal.

From a health point of view, sleeping for four hours is not good for your health. The latest research has found that adults should sleep a little more than 7 hours, which is the most suitable for the human body and is beneficial for longevity. It is generally believed that more than 80% of adults sleep for about hours a day, teenagers need more, teenagers need about 8-9 hours, and children need more, children need 10 hours of sleep.

But this is only for most people, there are individual differences. Some people take short sleeps and only need 4-5 hours of sleep every night. These 4-5 hours of sleep will not cause any physical discomfort to these people, so there is no need to force 6-7 hours, or 7-8 hours of sleep, so that they will feel uncomfortable.

Some adults may need to sleep for a longer period of time, perhaps 9-10 hours. This is a long sleeper, accounting for about 1%-3% of the population. So how long you sleep depends mainly on whether you can sleep well, and you can be clear during the day, and you don't feel tired or sleepy, so you don't have to worry too much about how long you have to sleep.
