In the theory of traditional Chinese medicine, not only the change of four seasons is a complete cycle, but also a set of corresponding health preservation theory, 24 hours. Because the ancients divided a day into twelve hours, this method of health preservation was specially called "twelve-hour disease-free method" by health experts in Qing Dynasty. Chinese medicine believes that the qi of meridians in the human body, like the tide, will fluctuate and flow between meridians with the flow of time, and different meridians are on duty at all times. If we can adapt to this change of meridians and adopt different methods, we can achieve good health preserving effect. Shihai (9- 1 1 at night) is the season of Sanjiao Classic. The word "sea" means the rebirth of life in ancient Chinese, so if you want your body to have a good starting point, you should have a good sleep from now on. For the elderly, it may be difficult to sleep, but no matter what way you take, try to fall asleep before 1 1: 30 in the evening. At midnight (midnight 1 1- morning 1), the gallbladder meridian is in season. This period of time is the "conscious" time that is particularly emphasized in TCM health preservation. In Huangdi Neijing, it is said that there are 1 1 organs in the human body that are supported by the function of the gallbladder meridian, so it is necessary to have enough high-quality sleep to ensure that the gallbladder meridian gets enough energy.
