Reiki is becoming increasingly popular with the medical community, with over 800 hospitals across the U.S. offering Reiki as a standard part of hospital care. A research study at Hartford Hospital, Connecticut indicates that Reiki improved patient sleep by 86 percent, reduced pain by 78 percent, and reduced anxiety during pregnancy by 94 percent. In addition, nurses report that Reiki helps patients experience less pain, stress reduction and it improves mental attitude, appetite, and reduces the negative side effects of chemotherapy, radiation and other medical procedures. Reiki also is given to staff (nurses & doctors) to help relieve stress, keeping them calm and focused.
