Combining the advantages and disadvantages of supine position, lateral position, prone position and curled position, the right position is healthier, followed by supine position. However, few people can really stay in the same sleeping position all night. So before you go to bed, try to choose the right sleeping position. How to sleep after falling asleep depends purely on fate.

There is also a saying in Qian Jin's cultivation in Fang Yao Daolin: "Bend your knees and lie on your side, which will benefit people's strength, win righteousness and restrain lying", and advocate "semi-lateral lying", which can ensure the smooth flow of qi and blood, relax the whole body and access the viscera. Good sleeping posture can eliminate fatigue and nourish the spirit.

When lying on the right side, the air intake of both lungs is the largest. In addition, the heart is located on the left side of the chest, and lying on the left side is easy to be squeezed, which is easy to increase the burden on the heart, so generally speaking, it is appropriate for people to lie on the right side.

It is worth noting that the pillow should not be too low when lying on your side, otherwise it will make your neck uncomfortable and easy to get stiff neck.
