Posture and health are very interrelated. According to the American Journal of Pain Management, posture affects and moderates every physiological function from breathing to hormonal production. Also, abnormal posture is evident in patients with chronic and stress related illnesses. Homeostasis and nervous system functions are ultimately connected with posture. As well as causing neck, back and shoulder pain, poor posture contributes to degenerative disc disease and other degenerative neck problems.
The American Journal of Pain Management also says despite the considerable evidence that posture affects physiology and function, the significant influence of posture on health is not addressed by most physicians. Unfortunately, most physicians are not really addressing the issue even though there is considerable evidence that supports that they are interrelated.
