First of all, let's talk about going to bed early, which generally means taking a rest around 10, because when you enter 1 1, various organs of the human body begin to repair and detoxify, for example, the liver begins to detoxify at 1 1. If you sleep late, why do you sleep at 1 o'clock? If you do this for a long time, then your liver will. If you extend their working hours for a long time, you will know how amazing it is. Look at those people who died of cancer around the age of 40. Basically, their living habits were not good when they were young, and they have been like this for so many years. So there was a later result. If you sleep late, the whole person basically has no spirit of people who go to bed early. Let's talk about getting up early first, because the human body has a fixed physiological cycle and laws, such as the brain. After a night's rest, it will resume exercise at a fixed time, and if you force it to sleep at this time, you will find that the more you sleep, the more you want to sleep, and after waking up, your spirit seems to be good and your whole body is very tired. If you go to bed before 1 1 every day, get up around 7: 00 in the morning and have a rest at noon 15-30 minutes.
