It was generally recognized by health care practitioners in ancient times. According to the medical thinking book, "Walk like a goose Wang Bu, sleep like a lion". Lying on the right side, also known as lion king lying, is the most suitable lying position for practitioners. The right lateral position refers to the sleeping position of the right arm under the body when sleeping.

The human heart is on the left, and the blood circulation itself is slow when people sleep. If you take the left position to press the heart, it is not good for your health.

Extended data

Lying on the left side is not recommended, especially for obese people and patients with respiratory diseases. Prone position will hinder thoracic dilatation, affect breathing and increase cardiopulmonary workload, which is not conducive to health.

In addition, the lateral rotation of the head when prone will not only lead to stiff neck and neck muscle sprain, but also cause respiratory discomfort and lack of depth, and even lead to cardiac ischemia and hypoxia. Therefore, people suffering from heart disease, hypertension and cerebral thrombosis should not choose prone.

When lying on your side, the spine bends forward into an S-shape, and the limbs are easy to put into a comfortable posture, which can relax the muscles of the whole body and help to eliminate fatigue.
