A year is divided into December and a day is divided into twelve hours. Health preservation should not only conform to the changes of the four seasons, but also follow the law of twelve o'clock a day. Now we divide a day into 24 hours, while the ancients divided a day into 12 hours. According to the meridian flow injection method of Chinese medicine theory recorded in Huangdi Neijing, 24 hours a day is divided into 12 hours, that is, two hours are equivalent to one hour, meridian refers to one hour, flow is flow, and injection is perfusion. In the meridian stream theory, 12 hour corresponds to the twelve branches related to the human body: purple, ugly, yin, hair (mǐo), Chen, Si (sǐ), Wu, Wei, Shen, You (yǒu), Xu (xū) and Hai. 12 hour is closely related to our internal organs and meridians. During this 12 hour, a zang-fu organ is on duty every hour. Therefore, it is necessary to maintain the relative viscera at every different time, so daily health preservation is also called 12 hour health preservation.

Zishi: 23: 00 am ~1:00 am-gallbladder meridian is on duty.

Midnight, also called "Midnight", also called "Midnight, Midnight", is the first hour of twelve o'clock. At this time, the underground Chuyang is gradually emerging, and biological buds have begun to sprout. It symbolizes that the fetus is conceived in the mother's abdomen, and also represents the image of the beginning of the sun spirit. The full spirit of the sun can promote the growth of human qi and blood, and sleeping is the spirit of nourishing the sun. So what should we do at this time? Very simple, that is to sleep. Falling asleep before childhood is the best care for gallbladder meridian. Usually, those who fall asleep before childhood wake up the next day with clearer heads and ruddier faces.

Clown time: 65438+ 0: 00 ~ 3: 00 in the morning-liver meridian is on duty.

According to the theory of hiding images in TCM, storing blood in the liver is one of the physiological functions of the liver, and "blood belongs to the liver when lying down", so staying asleep when ugly is the best care for the liver. If we don't rest in the middle of the night 1 3, the blood will continue to "transport in the meridians" and cannot return to the meridians to nourish the liver. Over time, it will affect the normal activities of the human body, and it is often prone to blood diseases, such as sallow complexion and hair loss.

Yin Shi: 3: 00 am to 5: 00 am-Lung Meridian is on duty.

This time is the time when the human body goes into deep sleep, and it is also the process when the qi and blood of the human body turn from static to static. Lung meridian is the source of qi and blood circulation in the twelve meridians. In Yin Shi, the circulation of qi and blood in the meridians flows to the lung meridian, so people with deficiency of qi and blood or lung diseases often wake up at this time. The common symptoms of lung qi deficiency are qi deficiency and fatigue, asthma when moving, and physical weakness. Clinically, according to the principle of "deficiency can replenish its mother", the method of "nourishing soil and generating gold" can be adopted, that is, the method of invigorating spleen and benefiting lung.

Mao (): 5: 00 ~ 7: 00-the duty of the large intestine meridian.

Lung and large intestine are opposites. The lungs spread fresh blood all over the body, and then promote the large intestine to enter an excited state, completing the process of absorbing water and nutrients in food and discharging garbage. Shi Mao's large intestine meridian is the best time to expel intestinal toxicity, clear lung turbidity and clean skin. Therefore, during this time, develop a good habit of defecating regularly and removing garbage toxins from the body. If the defecation reflex is not obvious, you can drink warm water or honey water on an empty stomach to wake up the gastrointestinal tract and promote defecation.

Morning: 7: 00 ~ 9: 00-stomach meridian is on duty.

4: 00 ~11:00-spleen meridian is on duty.

"Spleen governs transport and transformation, and blood governs." We need spleen to transport and transform what we eat, and spleen is the leader in managing digestion, absorption, excretion and human blood. After the food is digested and absorbed by the gastrointestinal tract, the subtle Shui Gu spreads to the whole body through the ascending and clearing action of spleen yang, and the spleen meridian is on duty, so as to prevent the spleen yang from being damaged. While strengthening the spleen, we should also nourish the stomach. "Spleen and stomach are the foundation of the day after tomorrow", and spleen and stomach are not divided. Try to avoid eating spicy food, so as not to hurt the stomach and spleen.

Noon:11:00 ~13: 00-Heart Meridian on duty

At noon, 12, the peak of a day in Yang Qi, is the critical point of alternating transformation of qi, blood and yin. As far as the changes of human qi activity are concerned, Yang is born at midnight and is most vigorous at noon. After noon, the yin gradually flourished, and the yin was the most vigorous at noon, so the exchange of yin and yang qi and blood in the human body was at noon. At noon, the heart meridian is in power, which has the functions of promoting blood circulation, regulating the mind, calming the heart and calming the nerves. It's best to be quiet and not move at noon, so your heart will drop. Taking a nap at noon is good for nourishing the heart and can make you energetic in the afternoon or even at night. Of course, the nap time should not be too long, and it is best not to exceed 1 hour.

Non-time (wè i):13: 00 ~15: 00-the responsibility of small intestine meridian.

At the end of the day, the yang begins to decline and the yin begins to rise, which is the best time to maintain the meridians of the small intestine. The small intestine can digest and absorb food from the stomach, distinguish turbidity, return water to the bladder and send garbage products to the large intestine. Shui Gu is subtle, that is, what we call nutrients are transported to the spleen, so we should finish lunch before 1 in the evening, so that the small intestine can absorb nutrients at the most vigorous time. Therefore, ancient doctors said "no food in the afternoon", and at this time, they often massage along the meridians, which can make two stools pass and make the whole body feel comfortable.

Applicable time:15: 00 ~17: 00-bladder meridian is on duty.

The bladder meridian is the longest and most numerous acupoint in the twelve meridians and Ren Du, and it is also the most important detoxification meridian for human body. The bladder stores water and body fluids. Water is excreted and body fluids circulate in the body. When smearing, pressing the acupoints on the bladder meridian properly can effectively dredge the bladder meridian, relieve the blockage of the meridians and ensure the smooth metabolism of water and liquid in the body. At the same time, you should drink water properly, or drink some tea that helps to detoxify, and promote the waste in the body to be excreted.

Unitary (yǒu), hour:17: 00 ~19: 00-the responsibility of kidney meridian.

You refers to 17 o'clock to 19 o'clock, also known as "sunrise", "sunset" and "dusk", indicating when the sun goes down. At this time, the kidney meridian is in season and the kidney meridian is the most vigorous, which is the best time to maintain the kidney meridian. Kidney storing sperm, now enter the time of storing sperm, it is recommended to rest at this moment, not easy to be tired and consume sperm.

Pericardium is the epicardial tissue of the heart, which can protect the normal work of myocardium and is also the channel for qi and blood to run. Beating the middle point between the two nipples (the tomb of pericardium meridian) can enhance the vitality of the heart and prevent heart disease.

During the period of Shihai (2 1 to 23: 00), Sanjiao Meridian was the most popular.

Sanjiao is the largest of the six fu-organs, which has the functions of controlling qi movement and dredging waterways. Triple energizer is connected with pulse. If people sleep when they go to sea, their pulse can rest and keep healthy, which is very beneficial to their health. Rest at this time will keep people in a good state of mind and body.
