What is Reiki?

Reiki is a Japanese healing art developed by Mikao Usui in the early 1920s, based on the idea that a universal life-force energy flows through all living beings and that disruptions in this flow contribute to stress, illness, and imbalance. A Reiki practitioner, trained and 'attuned' through a structured process, places their hands lightly on or just above specific areas of the body to guide this energy and encourage the body's own natural healing response. It is widely used today as a complementary therapy in hospitals, hospices, cancer centers, and wellness clinics around the world.

How does Reiki work?

From a scientific perspective, Reiki appears to work primarily by activating the parasympathetic nervous system — the body's 'rest and digest' mode — which lowers heart rate, reduces cortisol, and eases the physiological stress response. The gentle, intentional touch also triggers the release of endorphins and oxytocin, which reduce pain perception and promote feelings of comfort and safety. Whether or not a measurable biofield energy exists, the profound relaxation response Reiki reliably induces has real, measurable effects on the body.

What forms does Reiki come in?

A standard Reiki session lasts 45–90 minutes. The client lies fully clothed on a massage table while the practitioner works through a series of hand positions covering the head, torso, limbs, and back. Distance Reiki sessions, where the practitioner works remotely using intention and symbolic techniques, are also a recognized part of the tradition. Self-Reiki is taught at the first level of training and can be practiced daily at home.

Where it comes from:

Mikao Usui developed Reiki Ryoho ('spiritual energy healing method') in Japan around 1922 after a period of fasting and meditation on Mount Kurama. His student Chujiro Hayashi refined the hand positions, and Hawayo Takata brought the practice to the West in the late 1930s. It is now one of the most widely practiced complementary therapies globally, with an estimated 1.2 million Americans having tried Reiki and hundreds of U.S. hospitals offering it as an integrative service.

What does Reiki help with?

• Stress and anxiety: Reiki reliably triggers a deep relaxation response, lowering heart rate and blood pressure and calming the nervous system within a single session. People with generalized anxiety or high daily stress often report feeling significantly lighter and more grounded after treatment.
• Chronic pain: Multiple trials in hospital and clinical settings have found that Reiki reduces pain scores meaningfully compared to no treatment, particularly for people with conditions like fibromyalgia, cancer pain, or post-operative discomfort. It appears to reduce pain perception by calming the nervous system rather than blocking signals the way medication does.
• Cancer-related fatigue and distress: Reiki is one of the most studied complementary therapies in oncology. Research in cancer patients undergoing chemotherapy or radiation consistently shows improvements in fatigue, anxiety, pain, and overall quality of life, which is why it is now offered in many major cancer centers.
• Depression and low mood: Studies in both healthy adults and clinical populations show that regular Reiki sessions are associated with meaningful reductions in depressive symptoms and improved emotional wellbeing. The compassionate, intentional attention of a Reiki session itself may be part of what helps.
• Sleep problems and insomnia: Because Reiki promotes deep parasympathetic relaxation, many people find it easier to fall asleep after sessions, and some report improved sleep quality over a course of treatment. It is particularly useful for people whose sleep problems are driven by stress or an overactive mind.
• Post-surgery recovery: Several hospital-based studies have found that Reiki given before or after surgery reduces pain, anxiety, and the need for pain medication, and may support faster recovery. It is gentle enough to use in acute care settings without any risk of interference with treatment.
• Palliative and end-of-life care: Reiki is widely used in hospice settings because it provides comfort, reduces pain and anxiety, and helps patients feel cared for and at peace. Families and caregivers also benefit from the calming presence it creates.
• Burnout and emotional exhaustion: For people running on empty — emotionally depleted caregivers, healthcare workers, or anyone in a demanding role — regular Reiki sessions provide a structured pause that helps restore a sense of inner calm and energetic balance.
• Fibromyalgia: Small but encouraging studies specifically in fibromyalgia patients show reductions in pain, fatigue, and anxiety following Reiki treatment. Because fibromyalgia is closely tied to nervous system sensitization, therapies that calm the nervous system like Reiki are a natural fit.

What can Reiki help prevent?

• Stress-related physical symptoms (when practiced regularly as a wellness habit)

Which foods are rich in Reiki?

Reiki is a hands-on energy healing practice, not a substance found in food. However, the traditions surrounding Reiki emphasize dietary choices that support energetic clarity and nervous system balance. Prioritize whole, minimally processed foods — especially leafy greens, berries, nuts, seeds, and fermented foods — which support a calm, resilient nervous system. Anti-inflammatory foods like fatty fish, turmeric, and olive oil complement the stress-reduction goals of Reiki practice. Limiting caffeine, alcohol, and ultra-processed foods before and after sessions is commonly recommended by practitioners to help you stay in a relaxed, receptive state. Staying well-hydrated is also encouraged, as some practitioners believe it supports the body's recovery process after energy work.

What are the side effects of Reiki?

• Temporary emotional release (some people feel tearful or emotional after a session as tension releases — this is considered a normal, healthy response)
• Mild fatigue or drowsiness after a session (your body is in a deep rest state — plan accordingly)
• Temporary lightheadedness (rare, usually resolves quickly with water and rest)
• Vivid dreams or increased dreaming in the night following a session
• Very rarely, temporary worsening of symptoms before improvement (sometimes called a 'healing crisis' in energy medicine traditions)

Good to know:

Reiki is one of the safest complementary therapies available — it is non-invasive, requires no substances, and has an excellent safety record across decades of clinical use in hospitals and wellness settings. Most people feel pleasantly relaxed and calm after a session.

How much Reiki should you take?

• Recommended daily: One 60–90 minute session per week for active concerns; monthly maintenance sessions for general wellness. Self-Reiki can be practiced daily for 10–20 minutes.
• Best time of day: Any time works, but late afternoon or evening sessions are ideal if the primary goal is sleep improvement or unwinding from the day. Morning sessions suit those using Reiki to set a calm, centered tone for the day.
• With or without food: Avoid a heavy meal immediately before a session — a light meal 1–2 hours prior is comfortable. Drink water before and after. Avoid caffeine for a few hours before if possible, as it can make it harder to relax deeply.
• Time to effect: Relaxation benefits are felt immediately during or after the first session. Sustained improvements in pain, anxiety, or sleep typically emerge after 4–6 weekly sessions.
• How long to take it: For specific health concerns (anxiety, chronic pain, cancer support), an initial course of 6–8 weekly sessions is commonly recommended, followed by monthly maintenance. For general wellbeing, even one session per month provides meaningful benefit. Self-Reiki can be maintained indefinitely as a daily practice.
