In ancient times, a day was divided into 12 hours, that is, zi, ugly, yin, Mao, Chen, Si, noon, Wei, Shen, You, Xu and Hai, and each hour was equivalent to two hours now, so there was a regimen of 12 hours in ancient times. 12 hour is closely related to our internal organs and meridians. During this 12 hour, there is a meridian and a zang-fu organ on duty every hour. Therefore, we should keep their internal organs at different times.

Hours: From the evening 1 1 to the next morning 1, when courage is in season, the "season" is on duty.

When you are young, it is best to sleep to protect the yang.

This period of time should be the darkest time of the day, and the yang begins to grow. There is a saying in Huangdi Neijing that "all the eleven zang's are taken from bravery". This is what Chinese medicine says: "When you are young, courage is the order." This means that the other eleven organs depend on the growth of gallbladder and bile. If bile can grow, the human body will be fine. Zishi is the time when the meridians of traditional Chinese medicine run to the liver and gallbladder. If you miss this sleep time because you stay up late, then your liver and gallbladder will not get enough rest. Therefore, people who often stay up late will have health problems such as rough skin, dark spots and yellow complexion.

Noon and noon are two extremes. One is the weakest and the other is the strongest. After noon, the sun's spirit rises, and in the afternoon, the sun's spirit drops. From noon, Yang will drop, and when it drops to the cathode, it is the lowest time. Then people with qi deficiency are easy to overdraw the yang at this time; People with poor kidney disease are prone to accidents at this time; People with bad hearts are prone to sudden death at this time; People with hypoglycemia are prone to get sick at this time. Therefore, if you have the above phenomenon, you'd better take medicine in advance to ensure that you spend your time safely every day.
