Polyvagal Theory Autonomic Benefits

Dr. Stephen Porges' Polyvagal Theory establishes that extended exhalations activate the ventral vagal complex, sending afferent inhibitory signals to the sinoatrial node via the vagus nerve. This slows heart rate, increases respiratory sinus arrhythmia (RSA), and swiftly transitions the body from sympathetic hyperarousal into a restorative state of social engagement and physical relaxation.

Step-by-Step Instructions

4 Steps to Completion
1Phase 1

Select your breathing protocol (Resonance 0.1 Hz, Physiological Sigh, Box Breathing 4-4-4-4, or 4-7-8 Sleep).

2Phase 2

Set session duration (3, 5, 10, or 20 minutes) and toggle optional audio bell guiding.

3Phase 3

Align your breathing with the expanding (inhale), holding, and contracting (exhale) visual circle.

4Phase 4

Complete the session and observe the post-session autonomic coherence score and calming summary.
