The cervical spine has a forward physiological curvature, and prolonged head-down playing with cell phones, working at a desk, sitting and driving, working in front of the computer, and head-down movements for a long time, contrary to the forward physiological curvature of the cervical spine itself, will easily lead to straightening of the physiological curvature of the cervical spine, and serious anti-arch may occur, which is mainly reflected in the X-ray examination and is a manifestation of cervical spondylosis. You can help restore the physiological curvature of the cervical spine by relieving the tension of the surrounding muscles through cervical traction, acupuncture and massage physiotherapy. Normally, you should pay attention to avoid always low head movements, do more swimming, kite flying, badminton, sports with more head lifting movements, and pay attention to maintenance methods to prevent further aggravation or recurrence.
