Nadi Shodhana and Polyvagal Nervous System Balance

Nadi shodhana—alternate nostril breathing—is Patanjali's practice for balancing the body's energy channels and calming the mind. While ancient, this practice aligns remarkably with modern polyvagal theory: emotional dysregulation often reflects imbalance in the autonomic nervous system, oscillating between sympathetic activation (fight/flight) and dorsal activation (freeze/collapse). Nadi shodhana gently restores ventral vagal tone—the calm, socially-engaged state where emotion regulation is possible. By alternating breath between nostrils, the practice creates hemispheric balance and activates the parasympathetic nervous system. For DBT practitioners, this becomes a paced breathing skill with theoretical depth: you're not just distraction, you're systematically rebalancing the nervous system's baseline. The practice is portable—available during dysregulation moments—and works biochemically rather than cognitively, useful when rational mind is offline. Patanjali understood experientially what neuroscience confirms: breath rhythms directly regulate emotional states. For emotional dysregulation, nadi shodhana bridges ancient yogic wisdom and contemporary neuroscience, offering a somatic tool that works with the body's natural regulation capacity rather than fighting dysregulation through willpower alone.
