Energy healing therapies such as Reiki have been used in hospitals world-wide. According to the American Hospital Association, more than 800 American hospitals offered Reiki as part of hospital services in 2007 and the use of such services has been rapidly growing in hospitals and clinics.   There is also a growing body of research indicating that energy therapies are effective in reducing pain, depression and anxiety as well as accelerating the healing process and boost the immune system.

Surgical units in hospitals are using energy therapies such as Reiki before surgery to help people with anxiety and after surgery to help rebalance the body and accelerate recovery time and decrease the length of time medication is needed after surgery.

Such hospitals as Columbia University Medical Center, NY, New York-Presbyterian Hospital, NY, Memorial Sloan-Kettering Cancer Center, NY, Dana Farber Cancer Institute, MA, Sharp Memorial Hospital, CA and St. Joseph's  Medical Center, CA are just a few hospitals that offer Reiki services as part of their integrative program.
