Reiki: What the Research Says (2025)

Reiki is gentle, noninvasive, and widely used as complementary care. What does current research actually show?

Quick Takeaway

• Major health agencies say research is mixed: many studies are small or low quality, so results aren’t conclusive. Reiki appears safe as a complementary practice.

• More recent reviews suggest Reiki may help with anxiety, stress, pain, and overall quality of life—especially with a series of sessions.

  
  

The conservative view

• The U.S. National Center for Complementary and Integrative Health (NCCIH) states that Reiki hasn’t been clearly proven effective for specific conditions, but also notes there are no known harms.

• A Cochrane Review on anxiety and depression found the evidence insufficient—meaning we simply need more and better studies.

  
  

What newer research suggests

• Anxiety & stress: Some studies show Reiki sessions reduce anxiety and create a sense of calm.

• Quality of life: A 2025 review found improvements in overall well-being when people received at least 8 sessions of 60 minutes or more.

• Pain & relaxation: Results are mixed, but some research suggests Reiki can support comfort and activate the body’s natural relaxation response.

  
  

Why results vary

• Studies use different protocols (session length, number, practitioner style).

• Many are small studies or lack blinding, which makes results harder to compare.

• More high-quality research is needed—but positive signals keep emerging.

  
  

What this means for you

• Reiki is gentle, noninvasive, and safe as a complement to standard medical care.

• The strongest research signals are around stress reduction, relaxation, and quality of life.

• It should be used to support, not replace, medical treatment.

  
  

Suggested session rhythm (based on studies)

• For stress and anxiety: Try a short series of 6–8 sessions over 3–4 weeks.

• For ongoing well-being: Consider 8 or more 60-minute sessions, then adjust as needed.
