Why are so many things positively affected by one procedure?

The body is a self-healing organism. With your nervous system free from interference your body can start to bring back balance to multiple systems, allowing your body to function at its best.

By improving spinal alignment people experience improved posture. This postural balance leads to better body-weight distribution which improves the structures acting to stabilize the spine. As less energy is required to oppose gravity, you will have more energy to think, function, heal and maintain yourself.
