As we all know, the factors leading to cervical spondylosis are incorrect sitting posture, playing mobile phone, professional work (such as long working hours) and lack of exercise. However, there is another important factor that is easily overlooked, and that is sleep.
"Many people have neck and back pain, numbness of limbs and other discomfort after getting up in the morning, which is manifested as' stiff neck' symptoms. People usually think that this is caused by poor sleeping posture or cold wind. In fact, this may be caused by improper pillows.
Extended data:
Hard pillows are good for human health, but hard pillows make the contact surface between the head and the pillow too small, and the local pressure is too large, which makes people feel uncomfortable, and it is likely to cause too much pressure on the local nerves, leading to numbness or pain in the head, neck, back, arms and hands the next morning.
Too soft a pillow is difficult to keep the height of the pillow, because too soft will oppress the scalp and is not conducive to blood circulation. At the same time, there is also the problem of poor air permeability, which can not ensure adequate breathing during sleep, and there may be potential safety hazards.
Therefore, the hardness of the pillow should be moderate, and the height of the pillow is different in different sleeping positions. It must be noted that the height of the pillow is about 15-20cm when we lie on our back and side. For the health of cervical spine, please choose pillows rationally.
