What Is Reiki Therapy?

Check out this answer from Consensus:

Reiki therapy is a popular complementary treatment that offers potential benefits for stress reduction, mental health, and pain management. However, the current scientific evidence is inconclusive, and more rigorous research is needed to validate its effectiveness. As interest in complementary and alternative therapies continues to grow, Reiki may become an increasingly accepted adjunct to conventional medical care, provided that future studies can address the existing methodological limitations.

Reiki is an ancient Japanese healing technique that has gained popularity worldwide as a complementary and alternative therapy. It involves the transfer of energy through the hands of a practitioner to promote physical, emotional, and spiritual healing. Despite its widespread use, the scientific community remains divided on its effectiveness due to limited and conflicting evidence.

History and Theory of Reiki

Reiki was developed in Japan at the end of the 19th century by Mikao Usui of Kyoto. The term “Reiki” is derived from two Japanese words: “Rei,” meaning universal wisdom or spiritual energy, and “Ki,” meaning life force energy3 10. The practice is based on the belief that this universal life force energy can be channeled through the hands of a practitioner to balance the biofield and strengthen the body’s ability to heal itself4.

Practice of Reiki

Reiki therapy typically involves a practitioner placing their hands lightly on or just above the client’s body in specific positions. The practitioner then channels energy into the client to activate the body’s natural healing processes and restore physical and emotional well-being3 4. There are different levels of Reiki training, from basic self-care techniques to advanced practices that allow practitioners to teach others10.

Therapeutic Effects of Reiki

Stress and Relaxation

Reiki is often used to reduce stress and promote relaxation. Studies have shown that Reiki can help lower stress levels and improve overall well-being. For example, a study on caregivers of cancer patients found that Reiki significantly reduced stress levels and regulated blood pressure and pulse rate8.

Mental Health

Reiki has also been explored as a treatment for mental health issues such as depression and anxiety. A systematic review found that Reiki demonstrated a greater therapeutic effect over placebo for clinically relevant levels of stress and depression, although the evidence was less conclusive for normal levels of these symptoms3.

Pain Management

Reiki is frequently used for pain management, particularly in palliative care settings. It has been reported to relieve pain, decrease anxiety and depression, and improve the quality of life for patients with various conditions7. However, the small number of studies in this area makes it difficult to draw definitive conclusions.

Physiological Effects

Some studies have attempted to measure the physiological effects of Reiki. For instance, a pilot study explored the impact of Reiki on heart rate, blood pressure, body temperature, and stress levels but found no statistically significant differences between the Reiki and control groups5.

Limitations and Future Research

Despite the promising preliminary results, the scientific evidence supporting Reiki is still limited and often methodologically flawed. Many studies suffer from issues such as small sample sizes, lack of randomization, and inadequate blinding1 6. High-quality randomized controlled trials are needed to establish the effectiveness of Reiki more definitively1 3.
