It is often said that “a high pillow is not a worry”. However, from a medical point of view, the high pillow is not worry-free, we found that a considerable number of cervical spondylosis patients have the habit of lying on a high pillow. Long-term high pillow is often an important cause of recurrent pillow and cervical spondylosis. Yunyang County Hospital pain department Huang Wei Everyone has about l/4-1/3 of the day due to sleep and use the pillow. The pillow is indeed an important tool to maintain the normal position of the head and neck, especially for the head and neck section to maintain the physiological curvature of the forward projection is very useful. Because this physiological curvature is not only the cervical spine external muscle groups to ensure balance, but also to cushion the human movement from the lower extremities to conduct upward vibration, the cranial brain has a protective role, to maintain the physiological state of the spinal canal is indispensable conditions. If the pillow is too high, it is easy to make the head and neck excessive forward flexion, resulting in imbalance inside and outside the vertebral canal, the cervical spine posterior muscle groups and ligaments in this state for a long time and strain, the posterior wall of the dural sac in the vertebral canal is stretched tight, and displaced to the front and the formation of pressure on the cervical medulla. In the long run, once the posterior edge of the vertebral body and the corresponding part of the strain have obvious bone spur formation, it is easy to produce pressure on the cervical marrow, nerves and blood vessels, and cervical spondylosis symptoms such as neck and back pain and numbness of the upper limbs appear. Therefore, patients with cervical spondylosis and healthy people should not use high pillows to sleep. In order to maintain the physiological position of cervical convexity and prevent cervical degeneration, it is necessary to choose a pillow with the appropriate height.
