The document discusses how misalignments of the spine called subluxations can affect health by interfering with the central nervous system. Subluxations are caused by a lifetime of stress and trauma from accidents, poor posture, lack of exercise, and can occur without symptoms. They compress and irritate the spinal cord and nerves, reducing nerve transmission by up to 60%. While doctors focus on symptoms, chiropractors seek to address subluxations and the body as a whole in order to support optimal health and function.
