About Reiki
Reiki involves energy healing through the channeling of universal life force energy for balance and well-being.
Reiki was developed in 1922 by Mikao Usui, a Japanese Buddhist monk and scholar. According to tradition, Usui spent 21 days in meditation and fasting on Mount Kurama, seeking spiritual enlightenment and the ability to heal.
On the final day, he experienced a profound spiritual awakening and received what he called "Reiki" - universal life force energy. He discovered he could channel this healing energy through his hands to promote healing in others.
Usui opened a clinic in Tokyo and trained others in Reiki, establishing a system with specific hand positions and three levels of training (later expanded to four in some lineages). One of his students, Chujiro Hayashi, further developed the system and taught Hawayo Takata, a Japanese-American woman who brought Reiki to the Western world in the 1970s.
Since then, Reiki has spread globally with various lineages and styles emerging. While some practitioners maintain traditional Japanese approaches, others have adapted the practice to different cultural contexts. Despite variations, all Reiki shares the core principle of channeling healing energy through the hands.
Approaches
Styles & approaches
Reiki isn’t a single method. Practitioners may train in one tradition or blend several — here are the styles you’re most likely to meet.
Usui Reiki
The foundational modern Reiki lineage taught through levels, hand positions, and attunements.
Jikiden Reiki
A Japanese Reiki lineage that emphasizes traditional teaching and hands-on practice.
Karuna Reiki
A later Reiki system that uses additional symbols and compassion-focused practice.
Tibetan Reiki
A Western Reiki stream that incorporates Tibetan-influenced symbols or practices.
Distance Reiki
Uses Reiki practice at a distance rather than in the same room.
Mechanism
How it works
Reiki is best framed as a traditional, symbolic, energetic, reflective, or spiritual practice rather than a validated medical mechanism. Practitioners may use ritual, attention, sound, imagery, touch-free work, cards, symbols, prayer, or intention to support meaning-making and a sense of connection. People may explore it for reflection, calm, or spiritual context, while health claims should remain cautious and personal. A Reiki practitioner places their hands lightly on or just above the recipient's body, typically working through a sequence of hand positions covering the head, torso, and limbs.

Your first visit
What to expect from a session
A typical session outline to help you feel prepared
A Reiki session is a calm, fully clothed experience where a practitioner channels gentle energy to support your body's natural balance and relaxation.
Welcome and Intake
Your practitioner will greet you and ask about your health history, intentions for the session, and any areas of tension or concern. This is a relaxed conversation, not a medical interview.
Setting Your Intention
Together you may briefly set a focus or intention for the session, such as stress relief or emotional calm. There are no wrong answers — even simple curiosity is a perfect starting point.
Getting Comfortable
You lie fully clothed on a padded table, usually with a blanket available. Shoes come off, but that is typically the only thing you remove. Soft music or silence helps you settle in.
Practitioner Centering
Before touching you, your practitioner takes a moment to quiet their own energy and attune to the session. You may notice them standing still with eyes closed at the head of the table.
Energy Assessment
The practitioner may slowly sweep their hands a few inches above your body to sense areas of tension or imbalance in your energy field before any hands-on work begins.
Hand Placements
The practitioner gently places their hands on or just above specific areas — head, shoulders, chest, abdomen, legs — holding each position for several minutes. You may feel warmth, tingling, or a pleasant heaviness.
Receiving the Session
This is your time to simply rest. Many people drift into a deeply relaxed, almost dreamlike state. Some notice emotional releases like unexpected tears or a sense of lightness. All responses are welcome.
Closing and Aftercare
Your practitioner will gently signal the session's end and give you a moment to reorient. They will share any observations and suggest drinking water, resting, and noticing how you feel over the next day or two.
The Evidence
What does the research say about Reiki?
Reiki is widely used in integrative care settings. Research shows consistent relaxation effects, though the underlying mechanism remains scientifically unresolved.
Overall pictureModerate & Promising Evidence
Relaxation benefits are consistent; mechanism remains debated
Some studies report measurable relaxation responses from Reiki, though findings vary across trials and methodological challenges are well documented. Whether effects stem from energy transfer, therapeutic touch, or practitioner presence remains an open question in the research.
What the research showsConsistent relaxation effects; moderate support for anxiety and pain reduction.
Studies report small to moderate reductions in anxiety, pain, and stress markers among Reiki recipients. Quality-of-life benefits have been noted in cancer care settings. Evidence is promising but limited by small sample sizes and methodological challenges common to touch-based practices.
Why research is difficultDesigning rigorous Reiki trials presents genuine methodological challenges.
Creating a credible sham Reiki condition is difficult, and blinding participants is nearly impossible. Practitioner training and lineage vary widely, making results hard to compare across studies. The proposed mechanism — subtle energy fields — is not currently detectable by standard instruments.
Reiki as an alternative practiceReiki sits within the Alternative category of the MACH framework.
As an Alternative modality, Reiki operates from a framework — universal life force energy — that sits outside conventional biomedical models. Many people use it alongside, not instead of, standard care. Its value for some users may lie in the relaxation response, the quality of practitioner presence, or personal meaning-making.
Origins and traditionReiki was developed in Japan in 1922 and has since spread globally.
Mikao Usui developed Reiki following a period of meditation and fasting, framing it as a system for channelling healing energy. The practice reached the West in the 1970s through Hawayo Takata. Multiple lineages and styles now exist, ranging from traditional Japanese approaches to adapted Western forms.
Safety and appropriate useReiki is considered very low risk and is used across diverse populations.
Reiki involves no manipulation, substances, or invasive contact, making it suitable for most people including those with serious illness. It should complement, not replace, professional healthcare or your existing care team. Occasionally, sessions may surface strong emotions — having support available is advisable when processing grief or trauma.
Choosing a practitionerTraining standards for Reiki vary considerably — knowing what to look for helps.
Reiki training ranges from short weekend courses to multi-year study. Look for practitioners who are transparent about their lineage, training level, and scope of practice. A reputable practitioner will not make inflated outcome claims or suggest discontinuing medical care in favour of Reiki.

FAQ
Common questions
What is Reiki and how does it work?
Reiki is a Japanese energy healing practice developed by Mikao Usui in the early 20th century. Practitioners work with what is understood in the Reiki framework as universal life energy (ki), channelling it through light touch or near-body hand positions to support the recipient's natural healing capacity. From a contemporary integrative health perspective, Reiki is positioned as a complementary practice that promotes deep relaxation and parasympathetic nervous system activation — creating conditions that support recovery, stress reduction, and emotional regulation. The proposed energetic mechanism is not established in conventional science, but the relaxation response it induces is well-documented.
What does a Reiki session feel like?
Most people report a profound sense of relaxation, warmth, or gentle tingling during a session. Some experience emotional release, vivid imagery, or a sense of heaviness in the body. Sessions are typically conducted lying fully clothed on a treatment table in a quiet, calm environment. The practitioner places hands lightly on or just above specific body areas for several minutes each. Sessions generally last 45–90 minutes. Many clients fall asleep. There is rarely any discomfort.
Is there scientific evidence for Reiki?
Research on Reiki is limited in scale and quality, but growing. Several small RCTs and controlled studies have found benefits for anxiety reduction, pain management in cancer patients, and physiological markers of relaxation (heart rate, blood pressure, cortisol). A 2014 meta-analysis found moderate evidence for Reiki reducing anxiety and pain compared to sham treatment. Larger, methodologically rigorous trials are needed. The NHS in the UK and several major hospitals in the US have integrated Reiki as a complementary support for patients — not as a treatment for disease, but as a tool for wellbeing and comfort.
Can Reiki help with anxiety and stress?
This is where Reiki has the most consistent evidence. The deep relaxation response produced during a session reliably reduces acute anxiety and perceived stress. Regular sessions over several weeks have been shown to reduce baseline anxiety levels in multiple studies. The combination of stillness, human touch, intention, and therapeutic attention creates a powerful context for nervous system downregulation — regardless of the specific mechanism. For people who find verbal therapies difficult to access or who want a somatic complement to psychological work, Reiki can be a useful and accessible entry point.
Who should not receive Reiki?
Reiki is among the safest complementary modalities — it is non-invasive, requires no substances, and is suitable for most people including children, pregnant women, and the elderly. It is not a treatment for any medical condition and should never replace medical care. People with active psychosis or severe mental illness should discuss with their mental health team before engaging with energy-based modalities. Reiki should never be used as an alternative to urgent medical treatment.
