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:
There are fewer people lying prone, so this sleeping position is generally not recommended. Especially for obese people and patients with respiratory diseases, prone position will hinder thoracic dilatation, affect breathing, 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.
Lying on your side is a good posture. 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.
