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.

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.

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.

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.

• 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)

• 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.
