Breathing techniques used to alter arousal and consciousness, from clinical to non-ordinary-state contexts.

State of the evidence

Synthesized

Synthesized from 24 studies in the library · AI-generated, grounded in the abstracts below

Found by searching the library for Breathwork, holotropic breathwork, pranayama, conscious breathing, then ranked by relevance.

Breathwork research points in a mostly positive direction: across pranayama, box breathing, Holotropic Breathwork and mixed breath interventions, studies report reduced anxiety, stress and negative affect, improved mood and well-being, and some cardiovascular and sleep benefits, with small randomized trials supporting short-term effects. Results are not uniform: several trials show no between-group differences on pain, anxiety, depression or sustained attention, and reviews describe heterogeneous protocols and inconsistent autonomic findings. The main caveats are small samples, short follow-up, frequent lack of blinding or control groups, and multi-component programs that cannot isolate breathing itself.

How we analyze this

This synthesis reads the 15 most-cited and 10 most recent studies whose primary subject is Breathwork, up to 25 in all. The most-cited set anchors the established evidence, and the recent set surfaces work that is too new to have gathered citations yet.

A study qualifies only when Breathwork or a known alias appears in its title or keywords, so broad reviews that mention it only in passing are left out. Each study is read from its abstract, strongest evidence first, and the summary reports the direction of the results along with any conflicts and gaps.

From Supervised Program to Personal Practice: Design Rationale for an AI-Assisted Pranayama Application for Adolescents

INTERNATIONAL JOURNAL OF COMPUTER APPLICATION September 20, 2026 Bindu Madhavi Chintha* preprint

ABSTRACT Structured pranayama programs delivered in schools depend on a supervising instructor, a fixed schedule and an institution’s continued cooperation, and each of these ends when the program does. What remains available to a young person afterwards is rarely considered at the design stage. Existing digital tools offer limited help: few breathing and mindfulness applications have been...

High ventilation breathwork as a non-pharmacological model for inducing psychedelic-like states: expert evaluations of therapeutic potential and risk

npj Mental Health Research September 17, 2026 U. Lueken, Isabel Dziobek, Martha N. Havenith et al.

High ventilation breathwork (HVB) can induce altered states of consciousness with phenomenological similarities to those reported following administration of serotonergic psychedelics such as lysergic acid diethylamide (LSD), psilocybin or ayahuasca. Non-pharmacological methods capable of reliably eliciting such states may provide scalable models for investigating therapeutic mechanisms...
