High Ventilation Breathwork practices: An overview of their effects, mechanisms, and considerations for clinical applications

August 1, 2023 Guy W. Fincham, Amy Kartar, Malin V. Uthaug et al. 3 citations preprint

High Ventilation Breathwork (HVB), which involves deliberate manipulation of breathing, has a long history of use for psychological distress. This review examines its potential as a treatment for psychiatric disorders by analyzing its phenomenological and neurophysiological effects. Clinical observations and neurophysiological data show HVB produces extraordinary changes in subjective experience and profoundly affects central and autonomic nervous system functions by modulating neurometabolic parameters and interoceptive sensory systems. These effects may guide understanding and harnessing of HVB's volitional perturbation of psychophysiological states. Reports of beneficial effects for trauma-related, affective, and somatic disorders warrant further mechanistic research and rigorous clinical testing.

An exploratory study of breathwork-induced altered states of consciousness in experienced practitioners: the airways to alteration (A2A) trial

Frontiers in Psychology June 10, 2026 Guy W. Fincham, Edward Caddye, Amy A. Kartar et al.

A single session of high ventilation breathwork produced larger altered states of consciousness—including mystical experience, emotional breakthrough, and feelings of oneness—than body scan meditation in 24 healthy adults. One week later, breathwork was associated with greater psychological insight and self-reported behavioral change. Both groups showed improvements in stress, anxiety, depression, and well-being over time. These preliminary findings suggest breathwork can induce psychedelic-like effects and support further confirmatory research.
