The corresponding clinical symptoms of cervical spondylosis are aggravated after night, mainly for the following reasons: First, there is still work during the day, such as prolonged head bowing, desk work or prolonged sitting and driving, which further aggravates the strain and strain on the cervical spine and can produce an increase in symptoms. Second, compared to daytime, the temperature is lower and the humidity is higher at night, and if there is a cervical spine underlying disease, the muscles or tissues around the cervical spine are more sensitive to changes in the environment. Third, if there are bad habits at night, such as leaning on the sofa to watch TV, or sleeping with a pillow too high, these are also the reasons for the aggravation of cervical spondylosis symptoms. Therefore, if the symptoms worsen at night, you can no longer have cervical strain and strain work during the day, and you should go to the hospital for active treatment of cervical spine, such as traction, acupuncture, massage and physiotherapy for cervical spine.
