As the ancients say, if you obey heaven, you will live; if you disobey heaven, you will die. What is obedience to heaven? Lei Zhengke, chief physician of the Department of Traditional Chinese Medicine at Zhujiang Hospital of Southern Medical University, has been persisting in his research in this area. A few days ago, he gave a lecture on “Twelve Hours and Health”, the center of which is: twenty-four hours a day, the five organs and six bowels of the human body are in the process of dynamic changes. Therefore, of course, human work and rest need to follow the laws of nature.

Drink more water at this time to help digestion. Noon 11-1 (noon), is the most unbalanced time of the external yin and yang.
