The low pillow makes the blood supply unbalanced. High pillows are not good. Is it better to use a low pillow or no pillow at all? Director Lu said that it is unhealthy to use pillows too low or not. Some people suffering from cervical spondylosis think that they can recover without pillows. In fact, this idea is unscientific. If you don't put a pillow on your back, your body will lean back too much, and it is easy to open your mouth and breathe, resulting in dry mouth, sore throat and snoring. If you don't lie on your side with a pillow, the neck muscles on one side will cramp and ache due to overstretching and fatigue, resulting in "stiff neck".
The pillow is too low and the blood supply is unbalanced, which is easy to cause congestion and swelling of the nasal mucosa, which is very sensitive and will affect breathing. If the neck and shoulders are sore after waking up, it may also be caused by the pillow being too low or not using the pillow.
So, how high should the pillow be? It is pointed out in the ancient medical books in China: "When you lie on your back, you will feel comfortable, even if you lie on your back." In other words, the height of the pillow should be level with the trunk when lying on your back, that is, the pillow is one punch high when lying on your back and one punch and a half high when lying on your side. Generally speaking, the height of the pillow is 10- 15 cm, and the specific size depends on the physiological radian of each person.
In addition to the height of the pillow, experts believe that the hardness of the pillow should also be paid attention to. Excellent pillow, small contact area with head, increased pressure and uncomfortable scalp; On the other hand, the pillow is too soft to maintain a certain height, and the neck muscles are easily tired, which is not conducive to sleep, and the head is trapped in it, affecting blood circulation. Therefore, the pillow should be slightly Microsoft, without losing a certain hardness.
Pillows should also have some elasticity. If the pillow is too elastic, the head will be constantly subjected to external elasticity, causing muscle fatigue and injury. Such as "spring pillow" and "air pillow", are not considered as healthy pillows.
