The autonomic nervous system (ANS) controls involuntary bodily functions: heart rate, breathing, digestion, blood pressure, temperature regulation. It operates largely outside conscious control.
Two Branches
| Branch | Function | State | |--------|----------|-------| | Sympathetic | Mobilization | Fight or flight | | Parasympathetic | Recovery | Rest and digest |
Polyvagal Refinement
Stephen Porges' Polyvagal Theory further divides the parasympathetic into ventral vagal (social engagement, safety) and dorsal vagal (freeze, shutdown). The ANS can be trained toward "smart parasympathetic" — calm alertness.
In ONDA Life
Part 5 activates the Ventral Vagus for "calm alertness" — the heart beats powerfully and steadily, the brain is ready for effective dominance rather than panic.
Scientific Basis
Built on: Polyvagal Theory (Porges); Psychoneuroimmunology (Ader & Cohen); neuroplasticity research.
