There are numerous case histories of chronic cold sufferers having less or no colds after chiropractic care.  For example, when spinal motion was restricted, people tended to have more ear infections, bronchitis, and/or pneumonia.  However, if motion could be maintained or reestablished, patients recovered without complications. 

 

In another study, 92% of patients with chronic obsturctive pulmonary disease had improvement of their respiratory symptoms after spinal care.
