Chinese medicine says that "the order of heaven" is to follow the movement order of "heaven" itself, that is, southeast and northwest, that is, spring, summer, autumn and winter, that is, germination, growth, convergence and collection. If you violate this order, you will get sick. If you follow this order, you will live a long and healthy life. Therefore, the time medicine of TCM takes the twelve meridians as the reference of daily rhythm. Circadian rhythm refers to the ups and downs of yin and yang in a day and night. When a child is young, it means 1 1- 1 at night, which is also called "human hour". This moment was originally the time when the sun was the soul of all things, so it was called metaplasia. According to the theory of the rise and fall of Qi in TCM, Qi in human body is born from childhood every day. "After children, he will get angry, and in the afternoon, he will get angry" (Zhang Jiebin). Qi and blood circulation of gallbladder meridian in childhood. This is also the fundamental origin of "eleven zang-fu organs all depend on gallbladder" in Neijing, that is, the function of zang-fu organs depends on whether gallbladder can grow. People often have this experience in their daily lives. People usually feel sleepy at nine or ten o'clock in the evening, but staying up late until 1 1 will make them feel refreshed, which is the reason for the growth of gallbladder meridian. However, Yang's growing strength is still very small. Therefore, in the zodiac, "Zi" is "Rat". At this time, although Yang was as small as a mouse, he was extremely active. Therefore, to ensure that you sleep before 1 1 at night is to maintain this vitality through sleep. "Zi" stands for 1 1 month in the middle of the month, emphasizing the use of winter clothes to keep fit. Ugly time refers to 65438+ 0-3 o'clock at night. At this time, it is ugly time, and qi and blood flow in the liver meridian. Liver governs blood, therefore, ensuring sleep at this time is to nourish liver and gallbladder and nourish blood. Compared with qi, blood belongs to yin and is the main source of accumulation. Therefore, in the zodiac, the word "ugly" is "cow", which means that although the vitality of hair growth is great at this time, it cannot only rise but not fall, which is the beauty and broadness of China culture. So change the word "ugly" from "hand" to its third finger to indicate that. Traditional Chinese medicine "the liver is the official of the general, and the strategy cannot be made" also expressed the same meaning. The general is not only brave and good at fighting, but also must think twice before attacking. Yin Shi refers to the time when Yin Qi and blood flow into the lung meridian at 3-5 o'clock at night. In ancient times, China established Yin in the first month, and Liu Zhu in the twelve meridians started from the lung meridian, which meant the beginning. Who started it? It is the beginning of yang and the beginning of man. At noon, all parts of the human body began to turn from static to static, and the demand for qi and blood in all parts began to increase. At this time, the lung, as a "mutual aid official", must assume the responsibility of balancing the world (body). Once they fail to "declare" and "suppress blood", it will have serious consequences. For example, the increasing demand for qi and blood in all parts of the body will increase the burden on the heart, which is why many heart patients die at 3 or 4 in the morning (Western doctors probably don't understand why they died at this time). Healthy people should be in deep sleep at this time, that is, through deep sleep to complete the transition from static to dynamic life. However, people who are weak or the elderly will lose sleep or wake up. This is because the demand for blood in various parts of the body increases, and the corresponding blood obtained by the brain decreases. In the words of Chinese medicine, only "propaganda" does not exist, and life is naturally dangerous. Shi Mao refers to 5-7 o'clock in the morning, when qi and blood flow in the meridians of the large intestine. Traditional Chinese medicine believes that "the lung and the large intestine are in the exterior and interior". When the lung is full of yin, there should be normal stool when it is hairy, and the image of heaven and earth in Mao represents the opening of heaven and earth, representing February, and everything emerges from the ground because of the growth of yang. Chen Shi refers to 7-9 am, when qi and blood flow in the stomach meridian. At this time, it is as necessary and important for people to eat breakfast as the grass that emerges from the ground is nourished by the oblique wind and drizzle in March. Just as the sun be the spirit grows, the earth needs the surge of lightning and the moisture of spring rain. Shi Si refers to 9- 1 1 in the morning when qi and blood flow into the spleen meridian. Chinese medicine believes that the spleen governs transportation, which is also the reason why eating breakfast will not make people fat. If the spleen has a good transport function, it can be digested and absorbed smoothly. "April" should be in April, when the sun rises and the shadows hide, and everything in the mountains and rivers is lush. Noon means 1 1- 13 at noon, qi and blood flow into the heart meridian. Traditional Chinese medicine believes that the mind is "the official of the monarch, the god comes out", and the noon is the time when yin is born, and the yin is against the yang. It is the so-called "Yin and Yang God". For practitioners, it is a good opportunity to practice "meridians". For people who can't control their qi and blood, only sleep is the closest time to the so-called "intersection of heart and kidney", so they should do it at noon. Noon is in May. At the end of the season 13- 15 pm, qi and blood flow into the small intestine meridian. Shuowen said, "No, it's delicious. In June, it tastes good. " The taste of things is essence, and the function of small intestine in traditional Chinese medicine is to absorb essence. God refers to 15- 17 pm, and qi and blood flow into the bladder meridian. The bladder meridian is the pulse of the sun, reaching the top of the forehead. Qi deficiency and qi deficiency can easily cause headache or eye swelling. Healthy people at this time is a good time to study and research, so the ancients advocated "starting in the morning and ending in the evening." At this time, because qi and blood are easily lost to the brain, the learning efficiency will be high. Besides, the sun is responsible for gasification. Drink more water and eat some fruit at this time, which is good for your health. "Shen" should be in July and June. You's finger 17- 19 pm, and qi and blood flow into the kidney meridian. "Unitary" means achievement, and the month should be August. If the Shi Mao at 5-7 am represents the beginning of a day or a year, then the unitary at 5-7 pm represents the end of a day or a year. From this moment on, the small world of nature and human body began to meet in autumn and winter. At this time, the pathological changes of the body are all caused by the failure of the collection function of the kidney, and the low-grade fever of one yuan is very harmful to the kidney, especially for men in adolescence or after marriage. At that time, it meant 19-2 1 at night, and qi and blood flowed into the pericardium meridian. Chinese medicine believes that at this time, the yang of the human body should enter the turn of yin, when yin flourishes and yang declines, and "pericardium meridian" is the main pleasure, so people generally have entertainment at this time. Hai Shi refers to 2 1-23 pm, when qi and blood flow into the triple energizer meridian. Sanjiao is a concept that is not easy to explain clearly in Chinese medicine. The word "jiao" means roasting birds with a small fire. Therefore, three contacts means living in a warm atmosphere, whether it is up and down the human body or at home and abroad. China people use "dense" to describe it, and Chinese medicine attributes this blended state to Shaoyang ... so ". The last word is "sea" If "one" represents the innate chaos in ancient culture, then "sea" means returning to the original chaotic state and the cycle of life begins again. Therefore, in the traditional culture of China, we can always see the unity of its spiritual core. Whether it is medical ethics or philology, we can always see the ancient people's understanding and attitude towards the natural life of the universe. Not only does the sun rise as usual every day, but human life and life will also move and develop in the original order, and everything can be restarted at the end ... At this time, people should sleep peacefully and let the whole body (triple energizer) have a rest, and thus be completely relieved.
