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

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.
