Health care really needs to start with a little sleep. This sentence is very reasonable. Don't misunderstand this sentence. In the concept of health care, the body pays attention to "three-point nursing and seven-point training", that is to say, the effect of health care should be achieved through daily life such as sleep, diet and exercise.

How important is sleep to our human body? Usually everyone should have experienced it. If you don't sleep well after staying up late, you won't be in good spirits the next day. Then if you stay up late for a long time, you will be depressed for a long time, and long-term maintenance will lead to serious threats to your health.

In ancient China, Li Yu, a famous medical scientist, once said, "The key to keeping in good health lies in sleep. Sleep can be refined, sleep can nourish qi, sleep can strengthen the spleen and stomach, and sleep can strengthen bones and muscles. " It can be seen from here that the importance of sleep for health preservation has been deeply recognized by people since ancient times.

On the contrary, modern people have many misunderstandings about sleep, thinking that sleep is not important for health preservation, and they usually don't pay much attention to sleep. For example, many people think that sleeping seven or eight hours a day is enough, and it doesn't matter if they stay up late at night, as long as they make up for the daytime. Some people think that it will be quieter after midnight, so the work efficiency will be high at this time, which is also an act of adding mistakes to mistakes.

The neglected night time is the most beneficial to health. For most people, 9 pm to 3 am is the best time for healthy sleep. Even if you stay up late, it is best not to exceed 10:30 at night.
