The ancients did not know what scientific sleep was. They just followed people's own development and summed up a set of rules that are conducive to people's recuperation. In the wisdom of the ancients, everything in life has its own emphasis. Sleep plays an important role in people's lives, and a good sleep can refresh people. A good sleep must be matched with a good sleeping position and complement each other.
The ancients realized a long time ago that sleep was extremely important to people's health. In the early development, the ancients have deeply realized that sleep is extremely important to the human body. From a biological point of view, sleep is a kind of repair to human body and nervous system. The human body is like a precise instrument. In this case, each system plays a corresponding role and maintains the effective operation of the body.
But both the machine and the human body need rest. Therefore, sleep has become an essential thing. In life, about 30% of the time is spent sleeping. When people sleep, the nervous system and various systems of the human body are fully relaxed, and their physical strength and energy are greatly restored.
During sleep, cells are trimmed and renewed. The ancients liked this behavior very much and made appropriate adjustments according to the season and climate.
Even so, sleep is not only a simple physiological phenomenon, but also closely related to many factors. After thousands of years of exploration by the ancients, people's sleep is not only related to climate and season, but also related to people's sleeping posture.
There are many kinds of postures, so why does "sleeping with a corpse" become the target of public criticism? I believe that in daily life, sleeping posture is not limited to one or several. Some people like to lie on their backs, some people like to lie on their sides, and some people like to sleep on their stomachs. As early as thousands of years ago, the ancients recorded and evaluated these sleeping positions. The ancients commented that these three sleeping positions were also very vivid. The ancients called them "crouching tiger while crouching, paralyzing the corpse."
From the names of these sleeping positions alone, it can be seen that the ancients loved to lie on their sides and lie flat, but spurned sleeping on their backs. Then why does sleeping on your back become a target of public criticism?
Lying on your back was associated with a person's appearance after death by the ancients. After his death, the deceased usually lies on his back on the hearse. Lying on your back is also such a posture, which was considered by the ancients to be similar to "holding a corpse", so it was not respected by the secular. Moreover, this sleeping position, coupled with the hard pillows of the ancients, really has a great influence on people's comfort.
The ancients did not advocate prone position so strongly. In the eyes of the ancients, prone will oppress people's chest and have a great influence on breathing and heart movement. In severe cases, respiratory failure is likely to occur. The ancients may not have put forward a new viewpoint from the perspective of scientific development, but they abandoned this viewpoint from the perspective of comfort and health.
Lying on your side became a beacon in the eyes of the ancients. This behavior is recorded in many ancient books. According to the records in the Daojing of Kun Yuan, the ancients thought:
"Sleeping on your back, afraid of losing sperm and deliberately bending sideways."
As mentioned above, the ancients did not like lying on their backs or prone, but preferred lying on their sides. What's the difference between lying on the left and lying on the right?
It can be seen from some documents unearthed in ancient times that the ancients actually liked to lie on the right side. Although in the ancient concept, the left side is the top and the right side is the light, it seems that lying on the right side is more important in sleep. In fact, there are many reasons why the ancients respected lying on the right side. Because the heart of the human body is on the left, lying on the right can reduce the oppression of the body on the heart to a greater extent, which will make people feel more secure and comfortable, thus improving the sleep quality of the ancients.
Sleeping on the right side has become a new fashion posture, which not only reduces the oppression of the body on the heart, but also facilitates the peristalsis of the gastrointestinal tract, so it has become a beacon in the eyes of the ancients.
Having said so much, Bian Xiao only explained the influence of sleeping position on human body from a scientific point of view, and it doesn't apply to everyone. Some people like to lie prone, even if they are not so friendly to their bodies, they like to lie prone because they are used to it.
So, despite all this talk, life is only a few decades, and happiness is still the main thing.
