Abstract

Abstract Breathwork which increases ventilatory rate or depth represents an accessible nonpharmacological modality for potentially inducing altered states of consciousness (ASCs). Despite gaining traction as a therapeutic tool, empirical research remains limited, hence we conducted the first randomised-controlled trial (NCT06916312) on breathwork and ASCs. We examined the effects of a single session of high ventilation breathwork, compared to body scan meditation, in 24 healthy adults with primary outcomes of acute ASCs including mystical experience and emotional breakthrough. Sub-acute secondary outcomes were collected one week later. Breathwork was associated with considerable effects on oceanic boundlessness ( p = 0.007, r = 0.63), visionary restructuralisation ( p = 0.018, r = 0.60), total mystical experience ( p = 0.007 r = 0.66), oneness ( p = 0.018, r = 0.60), positive mood ( p = 0.007, r = 0.66), ineffability ( p = 0.038, r = 0.55), and emotional breakthrough ( p = 0.028, r = 0.45). At follow-up, breathwork induced substantially greater psychological insight ( p = 0.002, r = 0.67) and behavioural change ( p = 0.008, r = 0.60). Stress, anxiety, depression and wellbeing improved in both groups over time. Results from this trial indicate that breathwork induces greater acute psychedelic-like effects than meditation, paired with substantial effects on emotional breakthrough, insight, and behaviour. These novel findings are relevant for future characterisation of breathwork’s potential in therapeutic contexts.
