Side Effects of High Ventilation Breathwork: A Naturalistic Online Survey on Prevalence, Time Course, and Predictors

Open Mind May 28, 2026 Josephine Jörke, Lena Erdmann, Michael A. Rapp et al. preprint

This project investigates the safety profile of high ventilation breathwork (HVB). HVB has been shown to reliably induce altered states of consciousness (ASCs) comparable to psychedelics and has demonstrated multiple positive effects on mental health in clinical and non-clinical populations. Although HVB is regarded as generally safe when considering contraindications, intense somatic,...

From Altered States to Well-Being: A Mechanistic Model about Acceptance and Experiential Avoidance in High Ventilation Breathwork

2026 Lena Erdmann, Josephine Jörke, Martha N. Havenith et al. 1 citation preprint

This project investigates whether high ventilation breathwork (HVB) may support mental health through psychological mechanisms that have been proposed in the psychedelic-assisted therapy literature. HVB can reliably induce altered states of consciousness (ASCs) and has been discussed as a potentially low-threshold, non-pharmacological alternative to psychedelic interventions for conditions such...

Side Effects, Benefits and Associated Mechanisms in High Ventilation Breathwork: A Naturalistic Online Survey

2026 Josephine Jörke, Lena Erdmann, Michael A. Rapp et al. preprint

High ventilation breathwork (HVB) has received growing interest as a potential therapeutic tool in the context of the psychedelic renaissance and the expanding scientific research on mind–body practices. It involves intentionally increasing the speed and/or depth of breathing and is often conducted in groups, guided by facilitators and accompanied by evocative music. HVB has been reported to...

Shall we really say goodbye to first rank symptoms?

European Psychiatry July 17, 2016 Andreas Heinz, Martin Voss, Stephen M. Lawrie et al. 84 citations

BACKGROUND: First rank symptoms (FRS) of schizophrenia have been used for decades for diagnostic purposes. In the new version of the DSM-5, the American Psychiatric Association (APA) has abolished any further reference to FRS of schizophrenia and treats them like any other "criterion A" symptom (e.g. any kind of hallucination or delusion) with regard to their diagnostic implication. The ICD-10...
