Actually, it's a little hard to say. The main reason is that modern people have too little rest time and too much work time. If we really want to work at sunrise and rest at sunset, there is really no way, unless the elderly or people who pay more attention to health, or young people like us, it is difficult for students nowadays to rest according to this schedule.
However, I have to say that this timetable is most in line with the human biological clock and some methods of health preservation. You know, after 10 pm, flatulence such as liver and kidney is in a detoxification stage. If we don't have a rest, we still work or play outside, and some people even eat supper, which will do great harm to our health.
Therefore, as contemporary young people, we should pay enough attention to this problem so that we can have a normal rest time and have a healthy body to cope with our future life. Sometimes we just need to change our abnormal schedule, and we can really get enough rest. This is a sign of being responsible for your health. In a word, a healthy body is determined by good living habits.
