Sleep more and more every day, and leave your pillow under it every time you wake up. Recently found to be more serious. Does anyone know why?

This is called "running pillow", mainly because of pillow design and personal sleeping habits and posture. The latter is as dishonest as kicking a quilt while sleeping. The former is mainly because of sleeping on the side and sleeping on the back. Different people like different postures, such as me. Sometimes sleeping on your side will roll off the pillow. . . . Also, if the position of the back of the head is right, it will not go down more and more.

General pillows definitely don't have these functions. I have seen Tokyo Nishikawa (Pillow ~) in Japan before, with a history of more than 450 years. It is very famous in Japan, characterized by four divisions, sleeping on one side and sleeping on the back, the back of the head and the neck. It is a three-dimensional structure with a central depression.

I hope to adopt.
