Reiki for Pain Relief
Reiki for Pain Relief
Reiki is a gentle, non-invasive complementary therapy rooted in Japanese tradition. Practitioners place their hands lightly on or just above the body with the intention of supporting the flow of what is called universal life energy. It is used alongside conventional care as a tool for relaxation, stress reduction, and pain management (National Center for Complementary and Integrative Health [NCCIH], 2018). Reiki does not replace medical treatment; rather, it is designed to work with it.
How a Session Works
Sessions typically last 30 to 90 minutes, with the recipient lying down fully clothed. The practitioner moves through a sequence of hand positions intended to support energetic balance throughout the body. Proponents suggest that this process encourages deep physical relaxation, may ease the perception of tension and discomfort, and supports the body's own restorative processes (Dyer et al., 2019). Reiki is offered in hospitals, hospices, and wellness centers for conditions including chronic back pain, arthritis, fibromyalgia, cancer-related pain, and post-operative recovery. Shorter sessions of 10 to 20 minutes have also been explored in community settings with meaningful results (Richeson et al., 2010).
Most recipients report a notable sense of calm and ease during and after sessions, along with reduced discomfort and improved mood.
What the Research Shows
The body of evidence for Reiki as a pain management tool is growing, and increasingly encouraging, though it comes with important caveats.
A 2018 meta-analysis of four randomized controlled trials (212 participants total) found that Reiki produced a statistically significant reduction in pain scores on the Visual Analogue Scale (VAS), with a standardized mean difference of −0.927 — a large effect size relative to control groups (Demir Doğan, 2018).
A widely cited 2014 literature review calculated Cohen's d effect sizes across seven randomized trials. Within-group effect sizes for pain ranged from d = 0.24 to d = 2.08, and between-group comparisons ranged from d = 0.32 to d = 4.5, suggesting meaningful benefits for pain and anxiety beyond what rest alone provides (Thrane & Cohen, 2014).
A large-scale 2019 effectiveness trial conducted across private Reiki practices in the United States (1,411 sessions; 99 certified Reiki Masters) found statistically significant improvements in pain, anxiety, depression, fatigue, and overall wellbeing following a single session (Dyer et al., 2019).
A 2025 systematic review and meta-analysis of randomized controlled trials (661 participants) found significant improvements in quality of life following Reiki therapy (SMD = 0.28; p = 0.043). Subgroup analysis indicated that protocols involving eight or more sessions of 60 minutes or longer were most effective for sustained outcomes; acute sessions of 20 minutes or under also produced meaningful short-term improvements (Xu et al., 2025).
A 2017 review of 13 controlled studies found that 8 of them demonstrated Reiki outperforming sham (placebo) Reiki, suggesting benefits that go beyond the relaxation response or therapeutic touch alone (McManus, 2017).
Institutional Recognition
Reiki is recognized as part of integrative medicine by Mayo Clinic Press Mayo Clinic Press, which lists it among techniques used to support people through cancer treatment alongside massage, acupuncture, and meditation. Major U.S. institutions including the Mayo Clinic's integrative oncology center, Cleveland Clinic, and New York Presbyterian Hospital have incorporated Reiki into their programs.
The NCCIH acknowledges Reiki's safety record and its use in research contexts, while noting that there is no scientific evidence supporting the existence of the energy field thought to play a role in Reiki, and that Reiki hasn't been shown to have any harmful effects NCCIH (NCCIH, 2018). The agency's position reflects the general limitation of the existing research: most studies to date are small, and placebo-controlled design is genuinely difficult given that Reiki involves touch (NCCIH, 2018). As of July 2024, there are 140 Reiki research papers published in peer-reviewed journals, though most are pilot studies with fewer than 20 participants per group CRR (Baldwin, 2024). The field is actively evolving.
Realistic Expectations and Safety
Reiki has an excellent safety profile. No negative effects from Reiki have been reported in any of the research studies — which is understandable given that no substance is ingested or applied to the skin, and Reiki touch is non-manipulative Taking Charge of Your Wellbeing (University of Minnesota, n.d.).
Results vary person to person. Some people feel a meaningful shift after a single session; others find that cumulative sessions over time produce the most benefit. The research supports it most strongly as a complement to other therapies, not as a standalone treatment.
If you are considering Reiki for pain management: Seek a qualified practitioner (Reiki Master level is recommended). Always keep your primary care provider informed, particularly for acute injury, severe pain, or serious medical conditions. Reiki is not a replacement for medical care but can be a meaningful part of a broader, integrative approach to wellbeing.
