The movement of your spine is very important because spinal movement is estimated to generate 90% of the nutrition and stimulation to your brain. This means that if your spine is stiff and out of adjustment that your brain is paying the price. It was Roger Sperry, the Nobel Prize recipient for brain research who made this observation, linking a healthy spine with a healthy brain.
Imaging holding a bowling ball, close to your body, for a prolonged time. Now imagine holding that same bowling ball with your arms stretched out in front of you. With a slumped upper back (kyphosis) and a forward head (anterior head carriage) increased stress is on the spine. For every inch ones head is forward it can increase the weight of your head on your spine by an additional 10 pounds.
Over time anterior head carriage (where instead of being in alignment with your shoulder your ear is anterior to your shoulder) leads to muscle strain, disc herniations, arthritis and pinched nerves. It was the Mayo Clinic which made this observation.
With these anterior head carriage postural changes, the normal neck curve (lordosis) diminishes and researchers have observed that this can stretch the spinal cord as much as 5 to 7 cm. It was A. Breig, MD, a neurosurgeon, also a Nobel Price recipient, who made this observation. What happens with chronic increased spinal cord tension? We’re not sure, but it might be wise thing to prevent if we can.
In an article published in The Journal of the American Medical Association on aging and posture it was once stated that, “Deviations in the body’s center of gravity caused poor posture, which resulted in intestinal problems, hemorrhoids, varicose veins, osteoporosis, hip and foot deformities, poor health, decreased quality of life, and shortened life span.” Freeman JT, Posture in the Aging and Aged Body, JAMA 1957; 165(7) pp 843-846.
