Reiki for Psychological Disorders

Learn about Reiki, a form of alternative healing, that may reduce levels of depression, stress and pain.

Before engaging in any complementary medical technique, you should be aware that many of these techniques have not been evaluated in scientific studies. Often, only limited information is available about their safety and effectiveness. Each state and each discipline has its own rules about whether practitioners are required to be professionally licensed. If you plan to visit a practitioner, it is recommended that you choose one who is licensed by a recognized national organization and who abides by the organization's standards. It is always best to speak with your primary health care provider before starting any new therapeutic technique.

Background

The practice of Reiki, which may be as old as 2,500 years, is mentioned in Tibetan sutras and in ancient records of cosmology and philosophy. The name Reiki comes from the Japanese words rei, meaning "universal spirit," and ki, meaning "life energy." The Japanese physician and Buddhist monk Hichau Mikao Usui revitalized the practice of Reiki in the 19th century. Hawayo Tokata introduced Usui Reiki to the West in the 1930s.

Theory

Reiki practitioners believe that beneficial effects are obtained from a "universal life energy" that practitioners channel to patients, providing strength, harmony and balance to the body and mind. Reiki aims to treat health problems and to enable patients to feel enlightened, with improved mental clarity, well-being and spirituality. Reiki is sometimes administered to people who are dying, with the goal of instilling a sense of peace. Reiki masters believe that all living beings are affected by universal life energy, and animals may be treated in the same manner as humans.

It has been proposed that Reiki can lower heart rate and blood pressure, boost the immune system, alter hormone levels, stimulate endorphins and affect skin temperature and blood hemoglobin levels. However, these properties have not been well studied or clearly demonstrated in scientific studies.

In Reiki treatments, practitioners position their hands in 12 to 15 different positions, which are held for two to five minutes each. They may place their hands directly on a clothed patient or hold their hands one to two inches above the patient. Practitioners believe that hand positions can cover all of the body systems within 30 to 90 minutes. The number of sessions varies based on the judgment of the practitioner. Participants have reported warmth, tingling, sleepiness, relaxation or invigoration during Reiki.

Sometimes a technique called sweeping is used at the beginning of a session; sweeping involves the practitioner passing hands over the patient. This technique is proposed to allow the practitioner to detect areas of energy disruption, imbalance or blockage and allows the practitioner to cleanse patients of negative feelings, emotions or physical burdens.

Evidence

Scientists have studied Reiki for the following health problem:

Autonomic nervous system function
One randomized trial suggests Reiki may have an effect on autonomic nervous system functions, such as heart rate, blood pressure, or breathing activity. Large, well-designed studies are needed before conclusions can be drawn.

Depression and stress
There is evidence that Reiki can reduce symptoms of distress when compared with placebo. More information is needed before a conclusion can be drawn.

Pain
Patients in a preliminary ("phase II") trial of Reiki in combination with standard pain medications (with opioids) were reported to experience improved pain control. Further research is needed to confirm these findings.

Stroke recovery
In a randomized controlled trial, Reiki did not have any clinically useful effect on stroke recovery in patients receiving appropriate rehabilitation therapy. Selective positive effects on mood and energy were noted.

Unproven Uses

Reiki has been suggested for many other uses, based on tradition or on scientific theories. However, these uses have not been thoroughly studied in humans, and there is limited scientific evidence about safety or effectiveness. Some of these suggested uses are for conditions that are potentially life-threatening. Consult with a health care provider before using Reiki for any use.

Potential Dangers

Reiki is not recommended as the sole treatment for potentially serious medical conditions, and its use should not delay the time it takes to consult with a health care provider or receive established therapies. Serious adverse effects have not been reported in association with Reiki. Some Reiki practitioners believe that Reiki should be used cautiously in individuals with psychiatric illnesses.

Summary

Reiki has been suggested for many health conditions, but it is not well studied scientifically. Reiki should not be used alone to treat potentially dangerous medical conditions, although it may be used in addition to more proven medical treatments. Speak with your health care provider if you are considering Reiki therapy.
