In fact, modern people are facing more serious sleep problems, so we should pay more attention to sleep health. Understanding the experience of ancient people's sleep regimen will give us some useful lessons.
What do you mean, "Don't die lying down"? From the Analects of Confucius, the land of hard work, the original words are "sleeping without corpse" The "body" here. Lie on your back like a corpse. In other words, sleeping on your back, like a corpse in the eyes of the ancients, is very unlucky and unhealthy.
From the point of view of modern medicine, it does make sense. The study found that in all sleeping positions, sleeping on your back is the worst relaxation, and it is easy to put your hands on your chest and abdomen, causing discomfort and even nightmares.
Most importantly, sleeping on your back may induce sleep apnea, even saliva flowing into organs, and more seriously, it may lead to food reflux and suffocation. Therefore, it is not an exaggeration for the ancients to regard sleeping on their backs as a "corpse".
The saying that "lying down without covering your head" comes from "a thousand dollars are needed." The original text says: "If you don't cover your head in winter, you will live a long life.". The head is the intersection of all yang, the place where all yang meridians converge, and the qi and blood run vigorously. Covered on the head, on the one hand, it is easy to affect the operation of qi and blood, and on the other hand, it may cause sweating on the head and muscle relaxation, thus making the disease and evil take advantage of it.
The so-called "can't sleep in the north" comes from the old saying. The original text said: "Don't lie north yet, which means avoiding Yin Qi." "One thousand dollars for the Party" also said: "Don't lie on your head and don't sleep on the north wall."
Why did the ancients avoid lying in the north? Quite simply, the north is cloudy. As a meeting of yang, when sleeping, the head is located in the north, which is easily disturbed. Especially in autumn and winter, the evil of cold easily comes from the north. If you enter the brain directly during sleep, it will easily lead to wind-cold headache and even affect the operation of qi and blood.
The head is a place where many meridians converge, and the gas it receives will flow down from the head to the whole body like a shower. The orientation of the head during sleep is indeed a noteworthy problem.
Sun Simiao, an ancient doctor in China, advocated: "Ordinary people lie down, facing east in spring and summer and facing west in autumn and winter." That is, in spring and summer, the head sleeps in the east to meet the sun, and in autumn and winter, the head sleeps in the west to nourish the yin.
If you are in trouble or need to supplement the yang, you can simply keep your head facing east, which is a good way to sleep. The Book of Rites Jade Algae requires "East Head", that is, sleeping in the East all the year round. It is said to be the sunrise in the east.
Methods of sleep have been studied and discussed since ancient times. Cao Tingdong, a great doctor in the late Ming and early Qing Dynasties, summed it up particularly systematically, and his "two methods of exercise and verticality" was more respected by people.
"Fuck" must first "think about the top of the head" (the idea is in front), then "silently count the breaths" (breathe through the nose and recite the times), and then "return to the abdomen" (then bring the idea back to the abdomen). If you repeat this many times, you can make the appearance of "the heart is settled and inseparable" and gradually fall asleep.
"Vertical" is the antonym of "fuck". "Let it go, wandering in a distant, boundless and irrelevant place" (that is, even if you forget yourself, you can gradually fall into a hazy sleep.
No matter which of the above two sleep modes is adopted, you can't "exercise" too fast. The most important thing is to calm down and forget yourself.
Therefore, there is a difference between "slap" and "doze" in ancient times: "God lives in the eyes of a slap; God living in his heart is the beginning. " Only when the "heart" meets the "God" can it really fall asleep.
Ancient people were also very particular about sleeping position.
"Yi Xi sleeping tactics" advocates that if you lie on the right, you will bend your right foot; Bend your right arm and hold your head with your hand; Stick out your left foot and put your hand between your thighs. Lying on the left, opposite to the front.
Buddhism stipulates that lying on the right side, which is called "auspicious sleep", is also scientifically justified, because a person's heart is on the left side, and if lying on the left side, it may oppress the heart.
