How much sleep should a young person in his 20s get? There is a lunch break at noon, one hour .

If you can get 7-8 hours of sleep, just keep sleeping normally, so that the body's endocrine system will not be out of balance, and if you stay up too long, if you stay up too long, the hormones in the body will be out of balance, and the body will be vulnerable to disease.

8 hours, I slept when I was young, and I couldn't sleep when I was old.

No more than 8 hours a day!

Young people in their 20s like to sleep, and 7-8 hours of sleep are enough.

I can sleep for eight hours, I am not sleepy at noon, and I can take a walk.

Napping can be said to be a habit that men and women of all ages will have, especially when summer comes, because of the problem of long days and short nights, many people feel that they can't wake up, so how long is the normal nap time has become a question that everyone has, let's take a look.

Napping is good for the body, taking a nap for 20-30 minutes a day helps brain cells recover, and it can make you more energetic in the afternoon and improve the efficiency of work and study. Many people want to take a nap and wake up naturally, but it's actually okay. But as soon as you wake up, you should get up, move and get your body into a working state.

By 20 minutes, it is conducive to restoring alertness and energy, because the sleep time is very short, only in the non-REM sleep period during sleep, and wakes up soon after waking up, and can quickly go to work. It is suitable for office workers with short lunch breaks.

After waking up, the body usually has a shaky "drunken feeling", which is called "sleep retardation", which lasts for about half an hour before weakening, and the energy recovery is slow.

In about a few minutes, the brain will enter a slow-wave sleep during this long nap, which is conducive to memory. However, just like about 30 minutes of sleep, there is also the phenomenon of "sleep retardation".

Minutes of napping, this length of sleep, the brain will go through a complete sleep cycle, light sleep, deep sleep, REM sleep, can effectively restore the fatigue of the brain, at the same time easy to wake up, wake up more awake, will not be unresponsive.

15-30 minutes is the most appropriate.

After all, in life, both students and office workers have a 1-2 hour lunch break at noon, but a healthy nap is the most appropriate for 15-30 minutes, and the longest should not exceed 1 hour. If the time is too short to achieve the effect of resting, you will still doze off in the afternoon. If you sleep too long, you will fall asleep more deeply, and after waking up, you will feel a slight headache and general weakness, and it will not be easy to wake up, and it will also affect your sleep at night (insomnia).

A 20-year-old adult needs to get a full 8 hours of sleep a day.

Generally speaking, the best time for people to sleep is from 11 p.m. to 6 a.m., and it is extremely beneficial for the body to be able to fall asleep on time during this time period, especially from 11 p.m. to 3 a.m.

In addition, adequate sleep time is also extremely beneficial to the body, if you are over 60 years old, you need to sleep for about 6 hours a day.

Teenagers and young adults have about 8 to 12 hours a day, middle school students have about 9 hours a day, and college students and adults can basically have 8 hours a day.

A study released by University College London on May 28 said that sleeping less than 7 hours or more than 9 hours a day may have a negative impact on cognitive performance, including memory and reaction time.

Overall, people who slept less than 7 hours a day made 5% more mistakes on visual memory tests, while those who slept more than 9 hours made 9% more mistakes.

However, the researchers also said that further research is needed to clarify the relationship between sleep duration and changes in cognitive performance, especially since there is not much evidence linking the former with the risk of developing dementia, and further research is needed in this area in the future.

1.Normal people sleep for 6-8 hours, and some sleep for 10 hours ......2.Beauty sleep is available from 10 a.m. to 2 a.m.

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.

5.If you want to sleep normally, it is recommended to take oral sleep fragrance and stick to it for a period of time, it will be well improved.

The normal sleep time of 20-year-old people a day is 7-8 hours, the quality of sleep is not only determined by the length of sleep, the quality of sleep is also very important, if you want to improve the quality of sleep, the most important thing is to take oral sleep fragrance every day to regulate sleep, which can improve sleep, insist on taking it, can improve sleep quality and have a good sleep.

Normally healthy people should generally sleep for 7 to 8 hours, depending on the individual. 20-year-old people generally fall asleep quickly and sleep deeply, generally no dream or less dream, sleep 6 hours at night can fully recover energy, plus 40 minutes of rest at noon, is conducive to improving work efficiency and quality of life, according to the medical theory of the motherland, spring and summer should go to bed late and get up early, need to sleep 5 7 hours a day; In autumn, it is advisable to go to bed early and get up early, and you need to sleep 7 to 8 hours a day; In winter, it is advisable to go to bed early and wake up late, and you need to sleep 8 to 9 hours a day.

Sunny, hot days with short sleep durations; Bad weather, such as rainy days, cooler winters, and long sleep hours. With the increase of altitude in the area, the sleep time decreased slightly; With increasing latitude, sleep duration is slightly longer.

Not enough, the normal sleep time is generally more than eight hours

While the dangers of sleeping too little are well known, too much sleep can be just as harmful, according to a new study.

Researchers at the University of California, San Diego, found that people who slept 9-10 hours a workday appeared to have more problems with falling asleep and sleep quality, as well as other sleep disorders, compared to those who slept eight hours a day.

Sleep disorders include waking up in the middle of the night, waking up early in the morning, not being able to fall asleep again after waking up, and being tired during daily activities.

In addition, people who slept only seven hours per night compared to those who slept eight hours a day also reported that they had a harder time falling asleep and waking up in the morning feeling less refreshed.

The findings, published in the journal Psychosomatic Medicine, suggest that people who want a good night's sleep may not have to aim for more than eight hours of sleep.

Study author Daniel Kripke said it might be "a good idea" for people who sleep more than eight hours or eight and a half hours a night to consider reducing their sleep time. But he is also cautious that more research is needed to prove it.

Previous studies have shown that chronic sleep deprivation is potentially harmful. For example, one report showed that a person who habitually slept less than seven hours a night had a higher risk of dying in a certain period of time than someone who slept more.

It can be seen that a person's healthy sleep time should be 6-8 hours a day!

Recently, some foreign medical studies have found that many people who often feel tired do not feel sick or lack of sleep, but are caused by too much sleep! Why does too much sleep affect mental and physical strength? Because during sleep, blood circulation slows down, and nutrients and oxygen are greatly reduced to the brain.

If you sleep too much, your brain cells don't get enough oxygen and nutrients, and your ability to move is weakened. Sleeping too much reduces the activity of muscles and muscles, and the muscles get less oxygen and nutrients from the blood, so they become relaxed and weak, and naturally feel tired.

For many people who feel tired due to excessive sleep, if they reduce some sleep time and do appropriate physical exercise, they can fall asleep faster, sleep deeper, and eliminate the feeling of fatigue and weakness.

So sleeping a lot is not a good thing either.

According to the body's biological clock, it is more advantageous to go to bed around 11 o'clock in the evening, because brain activity and metabolism are between 10 and 2 o'clock when they need to get enough rest.

First of all, it is best to set your sleep time, if your sleep time is often more than eight hours, it is a normal person's sleep time (8 10 hours). But if you sleep from 2 a.m. to 10 a.m., then you definitely don't get enough sleep.

Therefore, you should make a schedule and go to bed at this time and wake up on time the next day. In addition, if you don't have much to do in the morning, you can take a nap and exercise a lot to keep your brain and body in balance.
