Reiki

Reiki is a form of therapy that uses simple hands-on, no-touch, and visualization techniques, with the goal of improvingthe flow of life energy in a person. Reiki (pronounced ray-key) means “universal life energy” in Japanese, and Reiki practitioners are trained to detect and alleviate problems of energy flow on the physical, emotional, and spiritual level.
Reiki claims to provide many of the same benefits as traditional massage therapy, such as reducing stress, stimulating the immune system, increasing energy, and relieving the pain and symptoms of health conditions. Practitioners have reported success in helping patients with acute and chronic illnesses, from asthma and arthritis to trauma and recovery from surgery. Reiki is a gentle and safe technique, and has been used successfully in some hospitals.
