The benefits of hot compressing neck and shoulder mainly include the following: 1. Hot compressing can improve the local blood circulation, so that the neck and shoulder muscles can get good blood supply. 2. it can improve the strain of neck and shoulder muscles, because after the blood supply of neck and shoulder muscles is improved, the degree of strain will be further relieved. 3. it can reduce the pressure of intervertebral disc, because through hot compressing, the strain of neck and shoulder muscles will be reduced and the tension will be enhanced. The pressure on the intervertebral disc can play a good role in relieving pressure, and after the pressure on the intervertebral disc is relieved, the clinical symptoms of cervical spondylosis, cervical disc herniation and other diseases can be improved. Therefore, the benefits of hot compressing the neck and shoulders are mainly to improve the degree of strain on the neck and shoulder muscles, reduce the pressure on the intervertebral discs, and relieve the early symptoms of cervical spondylosis.
