Scientific research says that sleeping on the right side may be the best sleeping position for human beings, but the best is universal. For example, fat people can only choose a sleeping position that is considered bad by science-sleeping on their back. If the fat man sleeps on his side, the whole weight is on his arm, so he won't sleep for long. The fat man sleeps on his back, his huge body is scattered on his broad back, and the oppression of each part is light. Plus, fat people sleep more dead, so they sleep longer.

Thin people can sleep in any position except the left, because the most important organ in the whole body is on the left, and the most important organ can't be oppressed, especially the bigger and heavier people.

To sum up, as long as gravity exists, the relationship between oppression and oppression will always exist. When oppression always exists, we have to choose a relatively comfortable oppression posture to sleep.

Extended data
