Reiki and Science. An Overview and most Relevant Research Articles

As Society has become increasingly Interested and Inquisitive about Holistic Complementary Therapies, various Sectors of the Medical Community and Universities around the World have begun to Study and Incorporate Complementary Therapies into their Practice, studying their Impact on Client Health and their Effectiveness in treating specific Symptoms, Emotions and Mental States.

Reiki Energy Healing is one of the most studied Techniques after Meditation and Yoga and there are at the moment around 5000 Approved Scientific Articles (plus of less relevant) about this Bio-Energetic Treatment.

A Reiki Treatment works on Human Bio-Field and it is Given by the Practitioner placing their Hands gently on your Body (or at the distance of 5 Centimeters) in a Pre-Determined Sequence of Hand Positions, spending several Minutes holding each Position. These Hand Positions are non-manipulative and during a Complete Reiki Treatment they cover both the Front and/or Back of the Client Body.

According with the Original Tradition of Reiki of Mikao Usui, Reiki is an Universal Energy Flow ables to Restore and Rebalance Human Energetic Body and Chakras by letting Flow and Integrating Energy where it misses, charging with Universal Energy. Reiki also raises the Vibratory Level of the Energy Field in and around the Physical Body where the negative Thoughts and Feelings are deposited, Clearing, Straightening and Harmonizing the Energy pathways, thus allowing the life Force to Flow in a Healthy and Natural Way. However at the moment there is an enormous diversity among Professionals in terms of Practice Styles, Trainings, and Experiences and just in le last few Years some Authorities as example National Center for Complementary and Integrative Health (NCCIH)  in USA,  I Comitati Tecnici Scientifici Regionali delle Discipline Bio Naturali (C.T.S.) , Association Conacreis (in Italy) and Asca Foundation (in Switzerland) are working to Regulate and Unified the Visions about this and other Holistic /Complementary Disciplines and the Complementary Operator Professional Figure. 

Traditional Medical Schools and HealthCare Professional Figures working in Hospitals and HealthCare Institutions doesn’t and cannot recognize the Original (Eastern) Definition of Reiki (as noted above). In Fact, there is not any Scientific Evidence in Official Science/Medicine about this Universal Energy (called Reiki) Existence. However Official HealthCare Institutions are even more open to Include Studies and Experimentations (also as Nurse Practice and/or Volunteering) in their Structures given the wide informal diffusion of This and other Complementary Therapies in the population and also because this Practice has no Medical Contraindications. Most of Scientific Studies introduces Reiki as a Bio-Photon Complementary Therapy working on Human Bio-Field.

A significant number of Scientific Studies have already observed that Reiki Treatments create a registrable Change in the General Persons Well-Being in terms of Improvement of Quality of Life (overall in Patients recovered for Cancer/Oncology disease) and it has Generalize Effects on Chronic Pain, Stress, Mood, Anxiety and Fatigue. On the other Hand, Clinical Changes are difficult and mostly Impossible to study because in deep contrast with the Medical Ethic and Protocols.

Here a List of some of the most Interesting and Relevant Scientific Research Articles about Reiki and Reiki Treatments

The effect of reiki on pain: A meta-analysis.Complementary Therapies in Clinical Practice | Vol 31, Pages 384-387 | May 2018

Objectives: Pain is one of the most common symptoms and may lead to important psychological, mental, and physiological problems in individuals. According to data by The Center for Reiki Research, Reiki is an effective approach to decrease the levels of pain, depression, and anxiety. Therefore, the aim of thismeta-analysis was to investigate the effect of Reiki on pain level.

Results: The result obtained after the final Reiki application was evaluated in VAS pain score. When Reiki (n = 104) group was compared with control group (n = 108), standardized mean difference was observed to be −0.927 (95% CI: −1.867 to 0.0124). Reiki was observed to cause a statistically significant decrease in VAS score.

Conclusions: Consequently, this meta-analysis revealed that Reiki was an effective approach in relieving the pain.


A prospective research study to investigate the impact of complementary therapies on patient well-being in palliative care  Complementary Therapies in Clinical Practice | Volume 31, Pages 118-125 | May 2018,

Summary: Eight patients; mean age 52.87years, range 40–64years presenting in the palliative care phase for life limiting conditions comprising one male and seven females agreed to participate in the study between March and September 2015. All eight participants reported perceived benefited from the therapies and that their identified concerns had been ameliorated. Participants reported feeling relaxed, calmer and being able to carry on with their daily lives and refocussing on themselves and what is important in life. Complementary therapies played a positive role, and therefore, an acceptable model of supporting palliative care patients.


Reiki for Hospice Patients and Their Caregivers: An In-Depth Qualitative Study of Experiences and Effects on Symptoms (S720) Journal of Pain and Symptom Management | Vol 53, Issue 2, Pages 420-421 | February 2017


Reiki Is Better Than Placebo and Has Broad Potential as a Complementary Health Therapy J Evid Based Complementary Altern Med  1051-1057 | September 2017

Conclusions: Viewed collectively, these studies provide reasonably strong support for Reiki being more effective than placebo. From the information currently available, Reiki is a safe and gentle “complementary” therapy that activates the parasympathetic nervous system to heal body and mind. It has potential for broader use in management of chronic health conditions, and possibly in postoperative recovery. Research is needed to optimize the delivery of Reiki.


The effect of Reiki therapy on quality of life of patients with blood cancer: Results from a randomized controlled trial. European Journal of Integrative Medicine | Volume 8, Issue 3, Pages 239-249 | June 2016

Objectives: Reiki therapy has been used for a variety of health issues. The aim of this study was to ascertain how Reiki therapy could help holistically in alleviating suffering in patients with blood cancer. Its main aims were to: (1) assess the effect of Reiki as a complementary therapy on the quality of life (QoL) of cancer patients, (2) compare the QoL of cancer patients receiving Reiki therapy with the QoL of cancer patients who received sham Reiki therapy.

Results: Sixteen patients who had been allocated to the control group died after recruitment into the study and before they took part in the study or had answered the questionnaire. The Reiki group showed significantly more improvements in the general, physical, environmental, and social dimensions of the WHOQoL-Bref (< 0.05). Only the psychological domain did not reach statistical significance. Multivariate clustering using latent class models revealed that being younger (under 52), an unmarried male, and having a higher level of education contributed to a greater satisfaction with life in those you received true Reiki therapy when compared with sham Reiki.

Conclusions: These findings suggest that Reiki may be an effective and safe option for improving well-being in patients with blood cancer. These findings may lend support for the inclusion of Reiki into national health services as it may provide a useful contribution to improving patients’ welfare and consequently a better quality of life.


Reiki Brief Report: Using Reiki to Reduce Stress Levels in a Nine-Year-Old Child.The Journal of Science and Healing | Volume 10, Issue 4, Pages 253-255 | July–August 2014

Conclusions: Reiki may be a useful adjunct for children with increased stress levels and sleep disturbances secondary to their medical condition. Further research is warranted to evaluate the use of Reiki in children, particularly with a large sample size, and to evaluate the long-term use of Reiki and its effects on adequate sleep.


Reiki and related therapies in the dialysis ward: an evidence-based and ethical discussion to debate if these complementary and alternative medicines are welcomed or bannedFerraresi M, Clari R, Moro I, Banino E, Boero E, Crosio A, Dayne R, Rosset L, Scarpa A, Serra E, Surace A, Testore A, Colombi N, Piccoli BG | SS Nephrology ASOU, San Luigi (regione Gonzole 10), Orbassano 10043, Torino, Italy | June 2013

Summary: this paper debates the current evidence on Reiki and related techniques as pain-relievers in an ethical framework, and suggests that physicians may wish to consider efficacy but also side effects, contextualization (availability and costs) and patient’s requests, according also to the suggestions of the Society for Integrative Oncology (tolerate, control efficacy and side effects)


Practicing Reiki does not appear to routinely produce high-intensity electromagnetic fields from the heart or hands of Reiki practitioners. Baldwin AL, Rand WL, Schwartz GE. | Laboratory for the Advances in Consciousness and Health, Department of Psychology, University of Arizona, Tucson, AZ 85724, USA | December 2012

Objectives: The study objective was to determine whether Reiki practice increases the electromagnetic field strength from the heart and hands of Reikipractitioners.

Results: For all subjects, under all conditions, sensors closest to the heart and the hands produced spikes of 2 pT corresponding to the heartbeat. Recordings from 2 Masters and 1 volunteer showed a low-intensity sine wave oscillation of 0.25-0.3 Hz (intensity 0.1-0.5 pT) whether or not they were practicingReiki. This oscillation probably reflected respiratory sinus arrhythmia, judged by comparison with recent previous studies. These signals were not detected in the original studies. In the current study, no electromagnetic field intensities greater than 3 pT were observed in any of the recordings

Conclusions: Practicing Reiki does not appear to routinely produce high-intensity electromagnetic fields from the heart or hands. Alternatively, it is possible that energy healing is stimulated by tuning into an external environmental radiation, such as the Schumann resonance, which was blocked in the present study by the strong magnetic shielding surrounding the SQUID.
