Reiki is a non-invasive, fully clothed, technique for helping the body heal naturally.
How Does Reiki Work?
At the simplest, most obvious level, it appears that Reiki treatment helps lessen the impact of stress, releasing tension from the entire system. Not only does the person move toward his or her own unique balance in body, mind and spirit, but also, depending on the level of physical health when Reiki begins, the body's own healing mechanisms often begin functioning more effectively.
What is Reiki doing?
How exactly does Reiki release tension and help the body heal? Some scientists believe that we can actually see this energy or "life force" through the use of Kirlian photography. Although there is increasing research evidence documenting the effects of Reiki (such as lowered heart rate, blood pressure, and stress hormones; increased immune strength), we have only broad theories as to what causes these effects or the pathways through which the healing occurs.
The multi-leveled, rapid response to Reiki suggests a complex process that engages many body systems, simultaneously or in quick succession, shifting the body from domination by the "fight or flight" (stress) response to the relaxation response, and supporting the body's own healing mechanisms. (For more information about the relaxation response, see the Mind-Body Therapies section.) Some researchers theorize that Reiki's physical, mental, emotional, and spiritual healing effect is triggered on a sub-physical level, perhaps in what science refers to as the biofield.
