Reiki in Clinical Practice

Peer review studies

The Center for Reiki Research (CRR) cites 33 Peer‑Reviewed Studies. The CRR maintains the most widely cited, continuously updated database of peer‑reviewed Reiki research which currently includes 33 studies, each with a critical summary.

Additional to the above a 2025 meta‑analysis identified several randomized controlled trials evaluating Reiki’s impact on quality of life, while a 2017 topical review examined English‑language clinical studies with more than 20 participants in the treatment arm. Additional review articles focusing on outcomes such as pain, anxiety, and palliative care further demonstrate that Reiki research spans multiple decades, though no single review provides a total study count.

Summary of what peer‑reviewed research says about the benefits of Reiki in clinical practice. The findings below synthesize results from systematic reviews, meta‑analyses, and curated peer‑reviewed studies, including the 33 studies catalogued by the Center for Reiki Research.

1.Quality of Life Improvements

A 2025 meta‑analysis of randomized controlled trials found that Reiki therapy is associated with measurable improvements in overall quality of life, based on pooled data from multiple RCTs.

These improvements often include:

Better emotional well‑being
Reduced fatigue
Enhanced sense of calm and coping

2. Stress Reduction & Relaxation

Across multiple clinical studies reviewed in integrative analyses, Reiki consistently shows:

Reduced stress levels
Deep relaxation responses
Lower physiological arousal (e.g., heart rate, tension)

Nursing and integrative medicine reviews highlight stress reduction as one of the most reliable outcomes.

3. Emotional Health: Anxiety & Depression

Several peer‑reviewed studies report:

Reduced anxiety during medical procedures, cancer treatment, and chronic illness care
Improved mood and reductions in depressive symptoms in some populations

These effects are often comparable to other relaxation‑based complementary therapies.

4. Pain Relief

Reiki has shown moderate reductions in pain across various conditions, including:

Post‑operative pain
Cancer‑related pain
Chronic pain conditions

While not a replacement for medical treatment, studies suggest Reiki may serve as a supportive adjunct for pain management.

5. Support for Healing & Recovery

Some studies reviewed in integrative analyses indicate:

Faster wound healing in certain contexts
Improved physiological markers of relaxation that support recovery

Evidence here is promising but less consistent than for stress and anxiety.

6. More Than Placebo?

A peer‑reviewed topical review examining controlled studies with >20 participants concluded that Reiki performs better than placebo in several well‑designed trials.

This suggests that Reiki’s effects are not solely due to expectation or attention.
