Wim Hof’s Breathing Method: Influence on the Autonomic Nervous System and Somatosensory Perception

Abstract

The rising prevalence of mental health challenges necessitates innovative interventions that extend beyond traditional therapeutic approaches. This dissertation explores the potential of the Wim Hof Method (WHM)—a breathwork technique combining controlled breathing, cold exposure, and meditation—as a complementary tool for improving mental health. Specifically, the study examines the WHM’s impact on the autonomic nervous system (ANS), somatosensory processing, and interoceptive awareness, with the aim of elucidating its mechanisms and therapeutic potential.Employing a randomized controlled trial (RCT) design, the research investigates the short-term effects of a 10-day WHM intervention on heart rate variability (HRV) as a marker of autonomic regulation and sensory processing patterns, as measured by the Adolescent/Adult Sensory Profile (AASP). While findings reveal modest changes in autonomic function and sensory processing, statistical significance was not achieved, underscoring the complexity of individual responses to the WHM. Theoretical frameworks, including polyvagal theory and interoceptive predictive coding, are applied to interpret the complex interplay between breathwork, autonomic regulation, and sensory engagement.The study identifies methodological limitations, such as the brief intervention period, reliance on self-reported measures, and a small sample size, which constrain the generalizability of the findings.
