The meaning of "not lying on your back" is exactly the same as that of "not lying dead". According to modern medicine, most people advocate lying on the side, preferably on the right side, which not only conforms to the body shape, relieves the pressure on the heart, but also relaxes the nerves, improves the quality of sleep and gives the tired body the greatest rest.
Many people think that "the legs are not stretched", which is the constraint of feudal ethics on women's behavior. Actually, it's not. Both men and women are indecent behaviors. On the one hand, this behavior will occupy a lot of public space, which is not in line with the traditional etiquette of the Chinese nation. In ancient times, it was considered as an insult to Sven to "show one's hips". For a woman, it can be said that she is a degenerate.
Lying on your back means sleeping on your back, which means don't sleep on your back like a dead man. First of all, in the eyes of the ancients, this would make people feel very taboo. Second, sleeping on your back is not good for your health. Such a sleeping position, with hands naturally placed on the chest, will oppress the heart and make people prone to nightmares and snoring, which will lead to chest tightness, shortness of breath, difficulty breathing and loss of energy. Third, people who sleep with their heads usually sleep tightly, react slowly to the outside world and have a dull mind.
China culture is extensive and profound. Our ancestors summed up many philosophical classics with their own originality. Because these ancient proverbs can be circulated for thousands of years, the vicissitudes of life are still brilliant. With the light of wisdom, we should follow these teachings of our ancestors.
