Reiki has its roots in ancient Japanese healing techniques from Shingon and Tendai Buddhist practices. The modern version of Reiki was popularized by Mikao Usui in the early 1900s and has since spread worldwide. The practice involves channeling universal ki (also known as chi or qi) into the client's energy field to promote overall health and wellbeing. In-person sessions involve hovering the hands over the body or light touching, but sessions can also be conducted at a distance using specific techniques (1, 2)

There is evidence to suggest that Reiki can improve mental health, reduce pain, and complement medical care by promoting relaxation. Although more research is needed, Reiki often performs better than a placebo in studies, and there are Reiki practitioners in hospitals and clinics around the world (3). Reiki can also be a spiritual experience, offering insight, fostering growth, and removing blocks on the client's spiritual path.
