Dark circles don't mean lack of sleep, and from the perspective of Chinese medicine, dark circles represent many symptoms, such as visceral problems, such as physical problems. Although you can't say that a person is unhealthy just because he has dark circles, the most basic thing is that he has some physical problems. The lightest thing is lack of sleep. He should sleep seven or eight hours a day, but he can only sleep five hours a day, or even less, which will lead to these physical problems for a long time.
We should pay attention to other parts of the body. Youth is not our pride and laissez-faire capital, so we still have to rest. Sleep at 2 o'clock and hang on the wall at 6 o'clock. You sleep at 3 o'clock and get up at 6 o'clock. It's really no exaggeration. Now that you feel young and unresponsive, your normal work and life will not be affected the next day. In fact, how can it not be affected? Just because you are young now, it may not be a problem when you show it in the future, because it will consume people's vitality invisibly.
To put it more bluntly, consuming people's vitality means shortening people's life span. How old can a person's body be maintained? That's not raising birds and fish after retirement, so that they can live a good life. The efforts they made when they were young will be reflected in their bodies. Those who are overworked and lack of rest will gradually show various problems with the increase of age and the decline of immune ability. At that time, show them again, and it will be difficult to cure them again.
