Ancient health care scholars have a saying that "sleeping like a bow". The so-called "lying like a bow" refers to the posture in which people lie on their side and bend over like a bow during sleep. In this posture, the limbs can be placed in a more comfortable position, and the muscles of the whole body can be satisfactorily relaxed.

According to modern medical theory, lying on the right side is better than lying on the left side. Because the heart is on the left, the opening of the gastrointestinal tract is on the right, and the liver is also on the lower right. Lying on the right side can make the heart bear less pressure, which is beneficial to the pumping of blood. The food in the gastrointestinal tract is normal, and the liver can get more blood. Therefore, lying on the right side is conducive to the digestion and absorption of food in the body, the smooth operation of blood circulation, detoxification and disease resistance.

Interestingly, the sleeping posture of "sleeping like a bow" is almost exactly the same as that of the fetus in the mother's womb, which is also beneficial to the life activities of the baby after birth. Of course, it should be pointed out that some patients or pregnant women cannot forcibly adopt the sleeping position of "sleeping like a bow" and should be treated differently according to the situation.
