Sleeping with a pillow is closely related to the human spine. When the human body stands up straight, it will be found that the human spine has a certain physiological curvature, which is not straight, but more like a curved curve with a little forward invasion. That's why you feel uncomfortable lying flat. If the pillow is not selected properly, the pillow is too high or too low, which may affect the curvature of the cervical spine. Not only do you feel uncomfortable when you sleep, but you may also have the risk of spinal diseases in the long run.

Harm of improper pillow sleep;
1, the pillow is too high: some people like to sleep on a high pillow, which is very comfortable. But in fact, this is not only "sit back and relax", but also affects your spine. The pillow is too high, indicating that the human body is in a posture of bowing its head, which is no different from playing with a mobile phone.
Usually, when people play with their heads down, they will feel uncomfortable for a long time, but when they fall asleep, their self-feeling function is greatly reduced. Even if the spine is compressed for a long time, they don't know, let alone think it's the pillow. If the pillow is too high when sleeping, it will change the normal bending of the cervical spine, causing muscle fatigue and ligament strain.
2, the pillow is too low: the pillow is too high or too low, and some people even like to sleep without a pillow. In fact, this will make the neck in a transitional state, and the mouth will unconsciously open when it is upturned for a long time. Sleeping like this easily affects the respiratory system, causing snoring and breathing with the mouth. Even if I fell asleep at night, I didn't know that a foreign body had entered my mouth.
