The neck will not become thicker if you twist it often, but this action can easily lead to degeneration of the synovial joints, so it is not recommended to do it often. This synovial joint disorder occurs because the cervical spine is in a state of chronic fatigue due to prolonged head down time, and is often accompanied by cold. This leads to a slight displacement of the synovial joints and produces a feeling of discomfort in the cervical spine. By shaking the neck, the synovial joints can be reset, and this uncomfortable symptom can be effectively relieved. However, over time, the ligaments and soft tissues around the synovial joints become loose and their elasticity decreases, resulting in local degeneration, wear and tear of the articular cartilage, osteophytes and calcification in the synovial joints, which can lead to more pain and unfavorable movement of the cervical spine. Therefore, after this situation occurs, try to avoid lowering your head for too long to avoid fatigue of the cervical spine, so as to prevent degeneration of the cervical spine, resulting in hyperplasia and calcification of the synovial joint parts.
