This is a term used to describe very specific types of intervention that affect the involuntary tension and movement patterns of our muscular system. When muscle tone is too low, its base value can be increased, when too high, it can be decreased. Hands-on techniques use spinal reflexes to achieve this. Positioning of the body in exactly the right way for maximum stretch or relaxation of a specific muscle are other ways to affect positive change in muscle tone.
Deep breathing exercises not only affect muscle tone and pain, but also decrease blood pressure by switching the involuntary nervous system from the fight-or-flight response to the relax-restore-repair mode. Learning practical ways for intentional physical relaxation is giving you a tool to use on your own to alleviate stress, which truly is a killer.
