The Body of Evidence
There is a significant body of evidence which suggests Reiki’s positive effects for the relief of stress, anxiety, sleep deprivation, chronic and acute pain, especially among staff with burnout syndrome. By helping to promote relaxation and improve sleep, Reiki may help to boost the immune system.

First Reiki Medic-Care findings
Preliminary results of the Reiki-Medic Care programme were presented at the International Congress of Integrative Medicine and Health in 2021. Interim analysis of interim data collected from doctors, nurses and paramedics treated through Reiki Medic-Care show improvements in their anxiety, stress, and levels of wellbeing.
The abstracts from the congress are available here (see abstract P13.07).
Our research mission
Recipients are able to opt in to complete a short
questionnaire addressing their symptoms before and after their four treatments if they wish to do so. Although there is anecdotal evidence that Distant Reiki is effective in reducing stress and burnout, there is very little published research on the topic. By opting to participate in this study, frontline medical professionals will make a valuable contribution to scientific research on Reiki.
Effects of Reiki on stress, anxiety, sleep and pain
Reiki can be helpful to both the body and mind. One of the most commonly reported effects of Reiki is that of relaxation or a reduction in stress. It is believed that a link may exist between ‘energy’ therapies and activation in the autonomic nervous system (ANS) (1,2).
For instance, Wardell and Engebretson (3) measured the biological effects of Reiki on the ANS and found significant reduction of anxiety and systolic blood pressure, and a significant increase in salivary immunoglobulin A (IgA) levels.
Three studies show that Reiki reduced burnout syndrome (BS) in health-care professionals. Diaz-Rodriguez et al (4) indicated that Reiki treatment produces a mild but significant relaxation response in nurses with BS symptoms. A second study (5) showed that a single session of Reiki brought immediate and measurable physiological stress relief to nurses as indicated by reduced blood pressure and enhanced secretion of the protective antibody IgA. Rosada et al (6) showed that Reiki treatments given weekly for six weeks significantly reduced BS among mental health clinicians. Specifically, Reiki reduced emotional exhaustion and feelings of depersonalization.

Related Research
At St George’s University Hospital, London, UK, the areas of anxiety, sleep and pain look promising for Reiki research based on raw data collection at the Connecting Reiki with Medicine project (7). This comes under the umbrella of Full Circle Fund Therapies a charity working within the hospital. The Connecting Reiki with Medicine website references resources for well-designed Reiki research studies, critical evaluations and systematic reviews which have been published in Clinical, Nursing or peer-reviewed journals.
Randomized, controlled clinical studies
In addition, short descriptions of the more recent randomized, controlled clinical studies (the scientific “gold standard”) published in peer-reviewed journals after 2017, are listed here.
