"Ling Shu Shun Qi is divided into four hours a day" records: a day is divided into four hours, the morning is spring, the day is summer, the day is autumn, and the midnight is winter. Understanding the principle of "four seasons in a day" can help us grasp the natural rhythm of the body in a day.

Get up in the morning like spring, clear the intestines and detoxify.

Yin Shi (3:00 ~ 5:00) corresponds to the lung meridian, so it is advisable to clear away heat and reduce turbidity. Three o'clock in the morning is equivalent to a day's beginning of spring. After Yin Shi wakes up, you don't have to sleep, or you will be more and more tired. At 5 o'clock, the human body is full of qi and blood, and some people will be sore all over. Getting up will help ease.

Shi Mao (5:00 ~ 7:00) corresponds to the large intestine meridian, so it is advisable to clear the intestine and detoxify. Chinese medicine believes that the lung and the large intestine are the same. After the lungs distribute fresh qi and blood to the whole body, they urge the large intestine to enter an active state, thus absorbing the surplus nutrients of food and discharging the dregs accumulated by metabolism in one day. Getting up at this time can help the large intestine to carry out full activities.

In the morning (7:00-9:00), corresponding to the stomach meridian, breakfast should be used for tonic. When the stomach wakes up, breakfast must be balanced and comprehensive, and we must resolutely avoid sloppy breakfast, Chinese food and dinner. On holidays, some people sleep until noon, and the dragon elephant still doesn't get up at this time, as if it has not experienced the bud of spring. Without spring, there is no summer, without exercise, there is no life, and the human body is prone to weakness and other discomfort without the support of yang.

Noon nourishes the soul just like summer rest.

4 o'clock (9:00- 1 1:00) corresponds to the spleen meridian, which should be digested and absorbed. At this time, the spleen meridian is in season, and the absorption capacity of transport and transformation is the best. If you haven't eaten it yet, you will be deficient in qi and blood, and your spleen and stomach will be damaged, which is prone to diseases such as stagnation of middle qi.

At noon (1 1 to 13), it is appropriate to take a nap to nourish the heart. Taking a nap at noon is good for maintaining the mind and promoting blood circulation, and it can also play a role in supplementing fire and helping digestion. Nap should not exceed 1 hour, otherwise it is easy to lose sleep, resulting in insomnia at night.

At the end of the period (13 ~ 15), it is appropriate to distinguish turbid secretions. When the small intestine is on duty, the small intestine can distinguish turbid secretions, so that water and liquid return to the bladder, dregs enter the large intestine, essence enters the spleen, and nutrition is adjusted and absorbed. Therefore, having lunch before 13 is helpful to fully absorb nutrition.

Dusk is like autumn, consolidating the foundation and cultivating the yuan.

Kidney excess (15 to 17) corresponds to bladder meridian, which is beneficial to promoting diuresis and removing blood stasis. During this period, memory and judgment are good, and it is the second prime time for work and study. So the ancients said, "teach in the morning and learn at night." When smearing, the body temperature is high, especially for those with yin deficiency. At this time, you can exercise more, drink afternoon tea and promote body fluid circulation.

The unitary time (17 ~ 19) corresponds to the kidney meridian, and it is appropriate to consolidate the foundation and strengthen the yuan. The sun sets, which indicates that it is about to enter the turn of autumn and winter in one day, corresponding to the season of harvesting and storing grain. Therefore, the evening is a good time for the human body to store the essence of the day, recuperate the kidneys, and consolidate the foundation and cultivate the yuan.

At that time (19: 00 to 2 1: 00), it is appropriate to be safe and steady. At this time, Yin Qi was in full bloom and Yang Qi was exhausted, which was the time when qi and blood flowed into the pericardium. Because cardiovascular and cerebrovascular diseases and psychological diseases belong to the jurisdiction of pericardium meridian, patients with related diseases can use pericardium meridian to massage related points for conditioning. At this time, take a proper walk, chat, enjoy your body and mind, and avoid strenuous exercise.

Night is like winter.

Shihai (2 1-23:00) corresponds to the triple energizer meridian, and it is appropriate to harmonize the hundred veins. At this moment, wait and see, it is advisable to look back, calm down, avoid exultation and great sorrow, and try to avoid getting angry or quarreling with others. In ancient times, Shihai was also known as "the time when man is determined". When Shihai falls asleep, all the pulse conditions are nourished, which can greatly replenish vitality and enhance immunity.

Midnight (23:00- 1) corresponds to the gallbladder meridian, so it is advisable to dive into the gallbladder meridian. The ancients defined 23 o'clock at the beginning of childhood as the beginning of a new day, corresponding to the winter, when Yang was born in an extreme state. At this moment, deep sleep is urgently needed to preserve the newborn Yang. Children fall asleep before children in the season, which is conducive to smooth bile metabolism and innovation.

Clown (1:00 ~ 3:00) corresponds to the liver meridian, so it is appropriate to sleep to protect the liver. When you fall asleep, you can give full play to the function of the liver to store blood and brew new blood. If you don't fall asleep, the liver is still consuming energy to support human activities, and it is difficult to complete the task of metabolism.
