Altered states of consciousness (ASCs), induced e.g. during psychedelic-assisted therapy, show potential to treat prevalent mental health disorders like depression and posttraumatic stress disorder. However, access such treatments is restricted by legal, medical, financial barriers. Circular breathwork may present a non-pharmacological hence more accessible alternative engage similar therapeutic processes. Scientific studies are only just emerging its physiological psychological mechanisms largely unknown. Here, we track experiential dynamics throughout session, comparing two forms breathwork: Holotropic Conscious-Connected breathwork. We that reduction in end-tidal CO2 pressure due deliberate hyperventilation significantly correlated ASC onset (r = -0.46; p < 0.001). Based on standard questionnaires (MEQ-30 11-DASC), the ASCs evoked resembled those produced psychedelics across several domains as ego dissolution, their depth predicted follow-on effects, including improved well-being reduced depressive symptoms. Further analysis showed different approaches highly outcomes. Our findings identify boundary conditions for arise context, shedding light functional well psychotherapeutic tool.

Abstract Breathwork is an understudied school of practices involving intentional respiratory modulation to induce altered state consciousness (ASC). We simultaneously investigate the phenomenological and neural dynamics breathwork by combining Temporal Experience Tracing, a quantitative methodology that preserves temporal subjective experience, with low-density portable EEG devices. Fourteen novice participants completed course up 28 sessions—of 20, 40, or 60 min—in days, yielding neurophenomenological dataset 301 sessions. Using hypothesis-driven data-driven approaches, we found “psychedelic-like” experiences were associated increased Lempel-Ziv complexity during breathwork. Exploratory analyses showed aperiodic exponent power spectral density—but not oscillatory alpha power—yielded similar associations. Non-linear features, like exponent, neurally map both multidimensional composite positive experiences, aspects psychedelic-like experience states such as high bliss.

Background: Non-ordinary states of consciousness induced by psychedelics can be accompanied so-called “peak experiences,” characterized at the emotional level their intensity and positive valence. These experiences are strong predictors outcomes following psychedelic-assisted therapy, it is therefore important to better understand biology. Despite growing evidence that autonomic nervous system (ANS) plays an role in mediating experiences, its involvement psychedelic experience poorly understood. The aim this study was investigate what extent changes relative influence sympathetic (SNS) parasympathetic systems (PNS) over cardiac activity may reflect subjective short-acting N,N-Dimethyltryptamine (DMT). Methods: We derived measures SNS PNS from electrocardiograms 17 participants (11 males, mean age = 33.8 years, SD 8.3) while they received either DMT or placebo. Results: Results show joint (“sympathovagal coactivation”) positively related participants’ ratings “Spiritual Experience” “Insightfulness” during experience, also being improved well-being scores 2 weeks after session. In addition, we found state balance between two ANS branches balance”) before injection predicted as well subsequent sympathovagal coactivation. Conclusion: findings demonstrate psychedelic-induced peak pave way development biofeedback-based tools enhance therapy.
