When a bone moves out of alignment in the spinal column it can put pressure on a nerve exiting the spinal cord at any particular level. These nerves control EVERY single function in our body, anything from digesting food to regulating the thyroid gland and hormone production. Misalignments of the spine cause abnormal stress and strain on the spinal cord. The spinal cord requires an abundance of energy to carry out its function, even at rest. After the age of 18, direct blood supply to our spinal cord, vertebrae, and discs is shut off and our body depends upon the movement of the bones in our back to pump blood, nutrients, and oxygen into our spine. Our nerve tissue demands high amounts of energy to function properly, so it is vital that each and every one of our spinal segments is moving properly. When the spine is misaligned, it takes a surplus of ATP (energy) to meet the high demands of our nervous system. This can cause the mitochondria (where energy is manufactured) of our nerve cells to malfunction leading to problems such as chronic fatigue, low energy, decreased performance, weight gain etc; eventually it can get so serious that it causes clinical diseases such as Multiple Sclerosis and Amyotrophic Lateral Sclerosis (ALS).
Bad posture, which is usually the side effect of spinal misalignment, can also cause our body to waste energy. The muscles and ligaments in our spine are specifically designed so that normal/correct posture is an efficient energy consuming process. The human body was designed to conserve energy, and conserving energy is the body’s number one goal in order to survive. By having to hold an abnormal position day in and day out, more energy (ATP) is needed to stabilize and move the spine and extremities. This creates a problem with our energy metabolism, and sets the stage for chronic disease.
Poor posture and spinal misalignments abnormally stretches and contorts the spinal cord. A study by Yamada et al. observed that when traction was applied to the end of the spinal cord in dogs, derangement of neural tissue metabolism was seen due to the longitudinal tensile stress. More specifically, it was the oxidative metabolism of mitochondria that was hampered. The cells that make up nerve tissue rely solely on oxidative metabolism for energy; therefore any alteration in the efficiency of this process in the mitochondria is likely to lead to progressive neuronal dysfunction. To put this in laymen’s terms, tension on the spinal cord interrupts nerve tissue metabolism, which disrupts transmission of nerve signals to organs, muscles, and joints in the body. Prolonged tension on the spinal cord can cause nerve damage leading to dysfunction and chronic disease. Lower your risk of chronic disease and make sure your spine is in proper alignment, today!
