The straightening of the physiological curvature of the spine is mainly caused by prolonged head bowing, lumbar activities and prolonged cervical and lumbar spine work in one posture, thus causing the straightening of the curvature of the cervical or lumbar spine. After this happens, you must pay more attention to keep warm, avoid getting cold, and avoid prolonged head-down and waist-bending activities. During bed rest, you can strengthen the muscle strength of the cervical and lumbar muscles, you can perform the exercise of five-point support of the back arch and flat support exercise, so as to strengthen the muscle strength of the neck and lumbar region and reduce the force on the spine of the neck and lumbar region. If necessary, you can hang more bars or go to the local hospital acupuncture and physiotherapy department to perform traction and physiotherapy treatment of the spine to promote the physiological curvature of the spine to straighten.
