Reiki, a healing practice codified in the early 20th century in Japan, was until recently an unexpected offering for a VA medical center. In Japanese, rei roughly translates to “spiritual”; ki is commonly translated as “vital energy.” A session often looks more like mysticism than medicine: Healers silently place their hands on or over a person’s body to evoke a “universal life force.” A Reiki treatment can even, practitioners believe, be conducted from miles away.
Reiki’s growing popularity in the U.S.—and its acceptance at some of the most respected American hospitals—has placed it at the nexus of large, uneasy shifts in American attitudes toward our own health care. Various non-Western practices have become popular complements to conventional medicine in the past few decades, chief among them yoga, meditation, and acupuncture, all of which have been the subject of rigorous scientific studies that have established and explained their effectiveness. Reiki is the latest entrant into the suite of common additional treatments. Its presence is particularly vexing to naysayers because Reiki delivers demonstrable salutary effects without a proven cause.
Over the past two decades, a number of studies have shown that Reiki treatments help diminish the negative side effects of chemotherapy, improve surgical outcomes, regulate the autonomic nervous system, and dramatically alter people’s experience of physical and emotional pain associated with illness. But no conclusive, peer-reviewed study has explained its mechanisms, much less confirmed the existence of a healing energy that passes between bodies on command. Nevertheless, Reiki treatment, training, and education are now available at many esteemed hospitals in the United States, including Memorial Sloan Kettering, Cleveland Clinic, New York Presbyterian, the Yale Cancer Center, the Mayo Clinic, and Brigham and Women’s Hospital.
