I remember reading in the magazine that if I sleep on my back all the time, my thighs are always pressed by my bed and my own weight. If you do this all night, or often, it's like a quilt. No matter how fluffy the quilt is, it will flatten out. So if you have the habit of sleeping on your back and want to have sexy upturned thighs, you should avoid sleeping like this for a long time.
Also, if you sleep to the left or right for a long time, it will lead to the situation that the left face is big and fleshy, and the right face is small and fleshy. This is actually the same as putting the baby to sleep. Tilt to one side for a long time, and the meat will fall to the piece next to the bed. After a long time, your face will have big and small reasons.
Also, if some people sleep with their mouths open for a long time, many people should have seen many heroines in TV dramas with their mouths open slightly, which is very cute. In fact, sleeping like this will make you grin in reality, and the reason is that if you sleep with your mouth open for a long time, your teeth will change after a long time. Because of inhaling and exhaling, your teeth will turn to the foreign minister.
In fact, these effects generally do not appear. These say that it is possible for a person to sleep like this every day.
