Meditation

Training attention on purpose, usually by resting it somewhere specific like the breath, a sound, or the sensation of the body. Mindfulness meditation, the most studied kind, emphasises noticing what shows up without arguing with it. It is a skill you practise, not a treatment you receive.

The documented roots are in ancient India, where the Upanishads describe breath control and seated posture and Patanjali's Yoga Sutras name dhyana as one of yoga's eight limbs, with parallel practices developing in early Buddhism. It entered Western clinical practice in 1979, when Jon Kabat-Zinn founded the Stress Reduction Clinic at the University of Massachusetts Medical School and built the eight-week Mindfulness-Based Stress Reduction course there.

Well studied

The best studied practice here. A Johns Hopkins review of 47 randomised trials found moderate evidence that meditation programmes ease anxiety, depression, and pain, with small to moderate effect sizes. Worth knowing: that same review found no evidence meditation beat other active treatments like exercise or medication. It is one good option among several, not a replacement for care.

Breathwork

Deliberately changing the pace, depth, or pattern of your breathing. Breathing is one of the few automatic functions you can take manual control of, which is why slowing it down measurably changes heart rate and heart rate variability. Techniques range from simple slow breathing to faster, more intense protocols.

Breath regulation, pranayama, is the fourth of the eight limbs in Patanjali's Yoga Sutras, with a parallel breath-attention practice in Buddhism. The modern Western forms are recent: Leonard Orr developed Rebirthing in California in the 1970s, and Stanislav and Christina Grof developed Holotropic Breathwork at the Esalen Institute in the mid-1970s, following Grof's years of psychedelic research.

Some good evidence

The mechanism is real and well documented: slow breathing shifts the autonomic nervous system toward its recovery branch. Outcomes are more modest. A 2023 meta-analysis of randomised trials found a small to medium effect on self-reported stress, and its authors explicitly warned against the gap between hype and evidence. Intense breathing protocols can cause dizziness or tingling, and can be difficult for people with a trauma history. Sit out anything that does not feel right.

Sound bath

A group session where you lie down and rest while someone plays sustained tones on instruments like crystal bowls, gongs, and chimes. There is nothing to do. Most people describe it as deeply restful. It is best understood as guided rest with live sound, not as a medical treatment.

Worth being straight about, since the usual story is wrong. Metal bowls have been made across the Himalayas for centuries, mostly as eating, storage and offering vessels. The Tibetan singing bowl as a healing instrument is a twentieth-century Western invention: there is no Tibetan word for a singing bowl, a standard catalogue of Tibetan ritual instruments lists twelve instruments and thirty-six variations with no bowls among them, and the practice enters the record around the 1972 album Tibetan Bells by two American musicians. Real metalwork, genuinely modern practice.

Early research only

We want to be straight about this one, because a lot of what gets written about sound baths is not supported. A 2025 systematic review found only 19 clinical studies worldwide, and rated the randomised ones as high risk of bias. Its conclusion is deliberately careful: singing bowls may have potential to help with anxiety, sleep, and mood. The most quoted study has no control group at all. Claims about healing frequencies, clearing blockages, or specific tones repairing the body are not supported by evidence. What we can say honestly is that people find it restful, and the early research points the same direction.

Ecstatic dance

Free-form dancing in a group, with no steps to learn and no one demonstrating at the front. Typically sober, usually without talking on the floor. Researchers file it under conscious dance, alongside 5Rhythms and Open Floor. There is no governing body and no standard format.

Its modern shape comes from Gabrielle Roth, who developed the 5Rhythms at the Esalen Institute in California through the 1970s. The drop-in format now called Ecstatic Dance started around 2000 at the Kalani Honua retreat centre in Hawaii, where Max Fathom set the template of freeform dance to DJ'd music with no alcohol or drugs, and it reached Oakland in 2008.

Early research only

Almost no direct research exists. A search of the medical literature returns a single study naming ecstatic dance: a survey of 1,003 dancers that found people who practise more often report higher mindfulness and life satisfaction. That is an association in people who already chose to be there, not proof the dancing caused it. Related work on moving in synchrony with others is stronger, but it studied taught, synchronised movement, which is a different thing from a free-form floor.

Contact improvisation

A partnered, improvised dance form started by Steve Paxton in 1972. Two or more people move together while keeping a rolling point of contact, sharing weight and playing with momentum and gravity. Nothing is choreographed. Its early practitioners deliberately never codified it or created a certification.

Originated by the American choreographer Steve Paxton, who danced with Merce Cunningham's company and helped drive the Judson Dance Theater. He made the precursor piece Magnesium at Oberlin College in January 1972, then presented the form that June at the John Weber Gallery in New York with around seventeen dancers, among them Nancy Stark Smith and Nita Little.

Early research only

Fifty years of practice and a serious body of writing sit behind this form, most of it in dance scholarship rather than medicine. The handful of academic papers are qualitative studies of how dancers read each other and make decisions mid-movement, which is genuinely the interesting question. No clinical trials exist. It earns its place in our events on the strength of the form itself.

Guided movement

Plain description rather than a discipline: a facilitator offers cues and prompts instead of teaching choreography or leaving the room to figure it out alone. In our events it is usually how the first twenty minutes works, moving people from standing still to moving together.

No single origin, and no founder to name. It describes a way of running a room that shows up across many lineages, from early twentieth-century somatic education through Chace's clinical work onward.

A descriptive term, not a studied one

This is a description of a format rather than a named method, so there is no body of research attached to the phrase itself. The nearest studied category is what the NIH calls mind and body practices, covering yoga, tai chi, and dance therapies. Rather than borrow a study about a different practice, we will just tell you what happens: someone guides the room from standing still to moving together, and nobody has to know any steps.

Live improvised music

An eight-piece band plays live and unscripted while the room moves. Nothing is pre-recorded and nothing is locked to a setlist, so the music can follow what is actually happening in front of it. This is a community music and movement experience, not music therapy, and no one on our team is working in a clinical role.

Early research only

A band that can hear the room and change what it is doing is a different instrument than a playlist. That is the whole reason we pay eight musicians instead of pressing play. Researchers have studied why moving together to music tends to feel bonding, including work on synchrony and endorphin release, though that work looks at group music broadly rather than at any one band. The wider evidence on music-based interventions is still early. We build it this way because of what happens in the room, and the research points in a direction we recognise.

Dance/movement therapy

A credentialed clinical profession, not a style of class. The American Dance Therapy Association defines it as the psychotherapeutic use of dance, movement, and embodied communication. Practitioners hold R-DMT or BC-DMT credentials and work in clinical settings. We are including it because people ask, and because we want to be clear that it is not what we do.

Founded by the dancer Marian Chace, invited in 1942 to work at St. Elizabeths, a federal psychiatric hospital in Washington DC, where her Dance for Communication groups became the basis of the profession. She was named the first full-time dance therapist in 1947, and the American Dance Therapy Association followed in 1966 with Chace as its first president.

Some good evidence

The strongest research on this page. A meta-analysis of 41 controlled studies with 2,374 participants found a medium overall effect on psychological health, though the authors flag methodological weaknesses and wide variation between studies. A separate 2024 review found dance worked about as well as other forms of exercise, not better. Our events are not dance/movement therapy and our facilitators are not dance/movement therapists.

Music therapy

Like dance/movement therapy, a licensed clinical profession. The American Music Therapy Association defines it as the clinical and evidence-based use of music interventions to meet individual goals inside a therapeutic relationship, delivered by a credentialed professional. Practitioners are board certified as MT-BC.

Some good evidence

Real clinical discipline with a real evidence base, and specifically not what happens at our events. If you are looking for music therapy, look for the MT-BC credential.

Reiki

A hands-on practice where a trained practitioner rests their hands lightly on or just above the body, moving through a set sequence of positions while you lie still and clothed. Practitioners describe the work as supporting the body's own healing response. A session is quiet and unhurried, and asks nothing of you.

Developed in Japan in 1922 by Mikao Usui, who taught it as a personal spiritual practice combining meditation, five guiding principles and hands-on work, before it travelled west and was reframed largely as a hands-on healing method. It is often described as ancient. It is about a hundred years old.

Early research only

The honest summary is that the evidence is thin rather than damning, and those are different things. The NIH states that reiki has not been clearly shown to be effective for any health purpose, that most studies have been low quality, and that results are inconsistent. A Cochrane review of reiki for anxiety and depression found only three eligible trials and concluded there was not enough evidence to say either way, which is a statement about how little research exists rather than a finding that it does nothing. A 2022 review of fourteen placebo-controlled trials found reiki outperformed sham reiki on some measures, though the authors called their own findings inconclusive. What is not in question is that there is no scientific evidence for the energy field reiki is traditionally described as working through. Worth saying plainly alongside that: an hour of quiet, undivided attention and light touch is a real experience, and controlled research on the practitioner relationship itself has found it produces meaningful benefit on its own.

The nervous system, and down-regulating

The autonomic nervous system runs the things you do not consciously drive: heart rate, breathing, digestion. It has two branches. The sympathetic branch handles fight or flight. The parasympathetic branch handles rest and recovery. Down-regulating is informal shorthand for shifting from the first toward the second.

Well studied

The underlying physiology is settled, textbook material, and slow breathing measurably shifts it. The vocabulary built on top is looser. Phrases like nervous system regulation and vagal tone come from the wellness industry rather than clinical practice, and dysregulation is not a diagnosis. We use the plain version here because it is more accurate, and because the real physiology is more interesting than the jargon.

Integration

The close. After the music stops, the room breaks into small groups, each with its own facilitator asking questions and holding the space, and people talk for fifteen to twenty minutes. Nobody has to speak. People trained in somatic work are on hand if something bigger surfaces. It is the part of the night we are least willing to cut, and the part most likely to be missing elsewhere.

The word comes into modern use through psychedelic practice, where clinicians from the 1960s onward, among them Stanislav Grof, Ralph Metzner and William Richards, built it into their protocols, drawing on ceremonial traditions that had carried the idea for far longer without writing it down. The first extensive academic analysis of integration as a concept was published in 2022, and most scholarship on it has appeared since 2017.

Some good evidence

This is the part of our work with the most research behind it, and the research is more interesting than a simple thumbs up. Frattaroli's meta-analysis of 146 randomised studies found that structured personal disclosure produces small but consistent improvements in psychological and physical health, and that sessions of at least fifteen minutes outperform shorter ones. Crystal Park's review of the meaning-making literature found that the quality of the processing matters at least as much as the quantity, and that experiences left unresolved tend to circle rather than settle. In clinical psychedelic research, Johns Hopkins safety guidelines treat a post-session meeting as standard protocol rather than a nice extra. Now the important counter-evidence: a Cochrane review of fifteen trials found that single-session psychological debriefing after trauma does not prevent PTSD, and in the longest follow-up the debriefed group had more than double the odds of PTSD a year later. The reviewers recommended that compulsory debriefing cease. That finding is about a specific practice: mandatory, one-off, immediately after a traumatic event, focused on recounting while people are still activated. It is the clearest evidence we know of that how a room is closed genuinely matters, which is why ours is voluntary, in small groups, held by a facilitator, with prompts that invite reflection rather than replay, and placed after the music has already brought the room down rather than at the peak. Two honest limits: the disclosure research studies individuals writing privately, not group circles, and the psychedelic work happens in clinical settings with screened participants. What carries across is the shape of the practice, not the setting.
