Due to the bowstring effect, the supraspinous ligament, interspinous ligament and erector spinae of the back are always in a state of tension, which leads to cervical spasm and ischemia, cervical curvature straightening, cervical degeneration, hyperosteogeny, intervertebral disc degeneration, and even compression of nerve roots, which damages spinal cord function, thus causing chronic strain.

It is suggested that patients should avoid looking down at mobile phones and using computers for a long time, get up and exercise every 1-2 hours, and actively stretch the cervical spine, which can keep the cervical spine in good mobility. By doing cervical exercise or swallowing-swallowing exercise, emergency resistance training, etc. The muscles around the cervical spine can better increase their functions and protect the stability of the spine, thus delaying the degeneration of the cervical spine and other parts of the spine.

You can also take the initiative to do functional exercises every day, such as swimming and jogging outdoors, which will help people relax physically and mentally, make the musculoskeletal system more developed, and thus provide better protection for human sports functions.
