There is a saying in the Yellow Emperor’s Canon of internal medicine, which is called “lying down causes blood to return to the liver” and “lying down” means sleeping. When people sleep, the demand for blood decreases, and part of the blood can be stored in the liver for re filtration. Therefore, if you sleep well, you can make the liver fully rest, which is the most important point of nourishing liver and blood.
In terms of sleeping posture, traditional Chinese medicine believes that sleeping sideways is more conducive to nourishing the liver and blood. Because the liver meridian is distributed on both sides of the trunk of the human body, whether it is on the left side or on the right side, the blood is more easily classified into the liver meridian, which makes people sleep quietly and starts the hematopoiesis function of the day. In order to make lying on your side more comfortable and reduce the pressure on your body, you can find a pillow between your knees, which is conducive to relaxing your waist and back.
It is generally believed that lying on the right side is the most scientific, because the heart is on the left side of the chest, and the heart is less stressed when sleeping on the right side. In addition, the mouth from the stomach to the duodenum and the small intestine to the large intestine is opened to the right, which is conducive to the normal operation of the gastrointestinal tract. Therefore, sleeping on the right side is not only conducive to nourishing the liver, but also the heart, intestines and stomach. However, it should be noted that the volume of the right lung of the human chest is larger than that of the left. Lying on the right side will affect the respiratory movement of the lungs and is not suitable for patients with emphysema and pulmonary fibrosis.
In addition, I don’t have to sleep on the right side all night. I can turn it over naturally for comfort.
