There is a direct link between the spine and energy levels. When the spine is unbalanced, fatigue is often the result. The 24 movable vertebrae, as well as the sacrum, hips, and pelvis, need proper alignment in order to make efficient use of energy. With proper posture, the body is positioned in such a way that the least amount of strain is placed on supported muscles and ligaments while in any position. This prevents fatigue because muscles are being used more efficiently, allowing the body to use less energy.
Any type of misalignment or unbalance (for example, having one leg shorter than the other) could translate into a considerable amount of wasted energy. The alignment of the neck and the shape of the neck are particularly important. While the head weighs between ten and 14 pounds, a misaligned neck could create an additional load of exponentially increasing pounds to the supporting tissues; fatigue can be exacerbated when the body is carrying an extra 20 or 30 pounds.
When the spine is healthy, the nervous system keeps the flow of energy between the brain and nerves balanced. If the spine is unbalanced, it creates a situation in which the body experiences physical and emotional fatigue, as well as a lowered immune response.
