High Ventilation Breathwork (HVB)—volitional manipulation of breathing used historically for psychological distress—produces extraordinary changes in subjective experience and profound effects on central and autonomic nervous systems by modulating neurometabolic parameters and interoceptive sensory systems. Clinical observations and neurophysiological studies indicate these practices may have therapeutic potential for trauma-related, affective, and somatic disorders. The evidence base suggests that the phenomenological effects of HVB can be understood and potentially harnessed through volitional perturbation of psychophysiological state, but further research is needed for detailed mechanistic knowledge and rigorous clinical testing of these potential uses.
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.
