History

The word "Reiki" is derived from two Japanese words: rei, or universal, and ki, or life energy. Current Reiki practice can be traced to the spiritual teachings of Mikao Usui in Japan during the early 20th century. Usui's teachings included meditative techniques and healing practices. One of Usui's students, Chujiro Hayashi, further developed the healing practices, placing less emphasis on the meditative techniques. An American named Hawayo Takata learned Reiki from Hayashi in Japan and introduced it to Western cultures in the late 1930s.

The type of Reiki practiced and taught by Hayashi and Takata may be considered traditional Reiki. Numerous variations (or schools) of Reiki have since been developed and are currently practiced.

Practice

Reiki is based on the idea that there is a universal (or source) energy that supports the body's innate healing abilities. Practitioners seek to access this energy, allowing it to flow to the body and facilitate healing.

Reiki may be offered in a variety of health care settings, including medical offices, hospitals, and clinics. It can be practiced on its own or along with other CAM therapies or conventional medical treatments.

In a Reiki session, the client lies down or sits comfortably, fully clothed. The practitioner's hands are placed lightly on or just above the client's body, palms down, using a series of 12 to 15 different hand positions. Each position is held for about 2 to 5 minutes, or until the practitioner feels that the flow of energy—experienced as sensations such as heat or tingling in the hands—has slowed or stopped. The number of sessions depends on the health needs of the client. Typically, the practitioner delivers at least four sessions of 30 to 90 minutes each. The duration of Reiki sessions may be shorter in certain health care settings (for example, during surgery).

Practitioners with appropriate training may perform Reiki from a distance, that is, on clients who are not physically present in the office or clinic.

Uses

According to the 2007 National Health Interview Survey, which included a comprehensive survey of CAM use by Americans, more than 1.2 million adults had used an energy healing therapy, such as Reiki, in the previous year. The survey also found that approximately 161,000 children had used an energy healing therapy in the previous year.

People use Reiki for relaxation, stress reduction, and symptom relief, in efforts to improve overall health and well-being. Reiki has been used by people with anxiety, chronic pain, HIV/AIDS, and other health conditions, as well as by people recovering from surgery or experiencing side effects from cancer treatments. Reiki has also been given to people who are dying (and to their families and caregivers) to help impart a sense of peace.

Effects and Safety

Clients may experience a deep state of relaxation during a Reiki session. They might also feel warm, tingly, sleepy, or refreshed.

Reiki appears to be generally safe, and no serious side effects have been reported.

Training, Licensing, and Certification

No special background or credentials are needed to receive training. However, Reiki must be learned from an experienced teacher or a Master; it cannot be self-taught. The specific techniques taught can vary greatly.

Training in traditional Reiki has three degrees (levels), each focusing on a different aspect of practice. Each degree includes one or more initiations (also called attunements or empowerments). Receiving an initiation is believed to activate the ability to access Reiki energy. Training for first- and second-degree practice is typically given in 8 to 12 class hours over about 2 days. In first-degree training, students learn to perform Reiki on themselves and on others. In second-degree training, students learn to perform Reiki on others from a distance. Some students seek master-level (third-degree) training. A Reiki Master can teach and initiate students. Becoming a Master can take years.

Reiki practitioners' training and expertise vary. Increasingly, many people who seek training are licensed health care professionals. However, no licensing or professional standards exist for the practice of Reiki.
