First of all, it is scientifically proved that normal people sleep for 6-8 hours for adults and 8- 10 hours for children. Children or teenagers should try to fall asleep before 9: 30 pm, and adults should try to fall asleep before 1 1:30 pm. In fact, I personally have reservations about how long I sleep, because I think how long I sleep should be determined by personal factors. For example, Huangdi Neijing once mentioned the problem of choosing sleep time according to seasons. For example, you should go to bed early and get up late in winter, and you can go to bed late and get up early in summer. However, Huangdi Neijing advocates the unity of man and nature, which is different from our modern health preservation in some aspects.
However, in any case, what we need to pay attention to is that we must not stay up late. I have consulted a lot of materials, and all of them have the same taboo, that is, whether in ancient times or in modern times, we all think that staying up late is very harmful to human body. Once, a famous doctor said, "The way to stay healthy is to go to bed before midnight. If I stay up late one day, even if I rest for half a year, I can't recover it. " It can be seen that normal work and rest is indeed an iron law that we must abide by.
In addition, developing a good schedule can not only make our bodies well regulated, but also keep us away from the pain of insomnia. So I hope everyone will follow the laws of nature and let us all have a good sleep.
