Resonant Breathwork As Multimodal Vagal–Interoceptive Modulation: An Empirical Synthesis Of Non-Invasive Vns, Breathing-Driven Interoception And Respiratory Tools, Piper Hutson, James Hutson
Resonant Breathwork As Multimodal Vagal–Interoceptive Modulation: An Empirical Synthesis Of Non-Invasive Vns, Breathing-Driven Interoception And Respiratory Tools, Piper Hutson, James Hutson
Faculty Scholarship
Resonant Breathwork is proposed as a layered, measurable intervention that modulates vagal activity and interoceptive processing through acoustic vocalization, respiratory mechanics, and biofeedback. This review synthesizes human empirical studies from 2022–2025 across five domains: (1) noninvasive transcutaneous auricular vagus nerve stimulation and acoustic or vocal vagal engagement; (2) interoception targets modulated by breathing; (3) respiratory rehabilitation tools, including oscillatory positive expiratory pressure and inspiratory muscle training; (4) virtual or augmented reality breath biofeedback; and (5) neuroimaging of high ventilation breathwork with music. Evidence shows taVNS can acutely increase vagal indices, with effects contingent on frequency and pulse width, while paced …

Introduction. Accumulating evidence indicates that exposure to electronic cigarettes (e-cigs) promotes sympathetic dominance and electrophysiologic instability in the heart, potentially culminating in arrhythmogenesis. E-liquids contain various formulations of nicotine and flavorings, but the effects of specific e-liquid constituents and their concentrations on e-cig-induced autonomic imbalance and electrical dysfunction are unresolved. To that end, we tested the hypothesis that e-cigs modify cardiac autonomic balance and ventricular arrhythmogenesis in mice dependent on e-liquid constituent type and concentration. Methods. Using a crossover design and a serial exposure regimen, ECG-telemetered male C57BL/6J mice underwent whole-body exposure to e-cig aerosols generated from e-liquids containing different …

Equine-assisted learning (EAL) may improve the health of older adults, but scientific data are sparse. This study investigated whether people aged 55 and older show increased heart rate variability (HRV) during EAL and awareness of bodily sensations that are overall pleasant. Subjects (n = 24) participated in mindful grooming during which they slowed their breathing and brushed a horse while noticing sensations in their body and watching the horse’s reactions. The subject’s and horse’s HRV were recorded simultaneously before, during, and after mindful grooming. For control, the same subjects performed mindful grooming with a plush simulation horse. During exit …

Equine-facilitated learning (EFL) helps people access their immediate sensations and feelings because horses, as prey animals, are continually aware of their environment and provide instant feedback to human behaviors and emotions. We hypothesize that during EFL, older people become more aware of their bodily sensations and emotions, leading to increased heart rate variability (HRV), improved self-esteem (Rosenberg scale), and improved immune function. Twenty-four subjects (age > 55) participated in a single 15-minute EFL activity, Con Su Permiso, during which they focused on their bodily sensations and the responses of the horse as they moved toward and around the horse. Subjects …
