Pillows are a necessity in people's daily lives, and their role is to maintain the normal physiological position of the head and neck when people sleep. From a medical point of view, the appropriateness of the pillow has a certain causal relationship with the formation of cervical spondylosis.
If the pillow is too high, it is easy to make the head and neck excessively flexed. If the muscles and ligaments behind the cervical spine are in this state for a long time, it will cause strain. Long-term strain can cause chronic degeneration of the bone at the posterior edge of the vertebral body and the corresponding part of the strain. At this time, it is easy to form a bone spur and compress the cervical spinal cord, blood vessels and peripheral nerves, resulting in neck and back pain and upper limb numbness. Such as cervical spondylosis symptoms.
If the pillow is too low or does not pillow, it is not desirable. Because low or no pillow will make the head and neck excessively bent, it is also easy to fatigue the neck muscles and ligaments. It will form a chronic strain and become a prelude to cervical spondylosis.
So, what kind of pillow is appropriate? The pillows that meet the physiological requirements should be: the shape is generally high in the height of the two ends, the middle of the low gold ingot shape; the length of the pillow is generally more than 10 cm to 16 cm above the shoulder width It can be; the height of the pillow is equivalent to the height of the fist after the head and neck are depressed. In addition, the raw materials of the pillow core can be made of buckwheat husks, thin velvet, bean husks, tea leaves dried after drinking, etc., so that it is soft and hard. Children's pillows should be slightly stiffer.
