brief introduction
From the point of view of natural science, it is best to wake up naturally, otherwise everyone will die. A regular life is a good foundation, but it is dangerous to work hard for a long time for the sake of "regularity" Scientists suggest that people with financial ability had better let nature take its course and don't damage their health just to flaunt morality.
Because after all, for farmers, "going to bed early and getting up early is good for health" is linked to the relations of production. If farmers don't get up early to work, herd cattle and farm, they will have no food. How to be healthy without eating for a long time? Therefore, if you are not a farmer or just trying to make a living, there is absolutely no need to torture and abuse yourself.
