In young people, the most common cause of cervical spondylosis is often not degenerative disc degeneration, osteophytes, disc herniation, but cervical instability due to chronic strain on the soft tissues around the cervical spine and the back of the shoulder, and the onset of cervical joint displacement under the action of certain triggers. Causes of this cervical spine physiological curvature abnormalities are: bad posture in work and life, such as office or classroom desk and chair height is not appropriate, long-term low head position; poor sleep posture, such as pillow too high or without pillow. Abnormal physiological curvature of the cervical spine can easily cause a series of clinical symptoms, such as neck weakness, headache and dizziness, nausea and vomiting, neck, shoulder and arm pain, arm numbness, and a feeling of heavy shoulders when working in a sitting position. The abnormal physiological curvature of the cervical spine mostly occurs in the third to fifth section (normal human cervical spine consists of seven cervical vertebrae), and this area may stimulate the tissue structures that cause blood pressure fluctuations and appear abnormal blood pressure. Patients with abnormal cervical physiological curvature can recover well after implementing correct treatment, maintaining good posture and reasonable neck and shoulder exercises. Recommended for long-term low head workers sitting neck and shoulder exercises: head forward flexion, backward extension; head left and right turn to look at the shoulders and back; stretch waist and chest, double upper limbs up, rear force out, that is, stretch lazy back; hands alternately pinch the back of the neck, while the head to the rear of the slight activity. Each of the above actions 3-5 times. When the above discomfort occurs, young people need to be alert to abnormalities in the physiological curvature of the cervical spine, which not only makes people feel uncomfortable, but also accelerates degenerative changes in the cervical spine, if necessary, promptly seek medical attention.
