When sleeping at night, what's the difference between lying on your side and lying flat? How has your figure improved?

Lying on your side is different from lying flat. When reviewing, it will not oppress the organs and limbs of the body, which is beneficial to the circulation of blood and the metabolism of breathing, and it is not easy to feel tired. Lying on your side can reduce the pressure on your spine, make your sleep process more stable and make you feel more secure. It can't really improve your health, because when you fall asleep, you don't know your posture.
