Parasympathetic Nervous System

The "rest and digest" branch of the autonomic nervous system — promotes recovery, digestion, and calm.

The parasympathetic nervous system (PNS) is one of two branches of the autonomic nervous system. It promotes "rest and digest" — slowing heart rate, stimulating digestion, and enabling recovery.

Key Effects

  • Slowed heart rate
  • Deep, diaphragmatic breathing
  • Activated digestion and peristalsis
  • Reduced cortisol
  • Social engagement capacity

In ONDA Life

Level 1 practices aim to activate the parasympathetic system through diaphragmatic breathing, extended exhales, and interoceptive awareness. The vagus nerve is the primary channel of parasympathetic influence.

Scientific Basis

Built on: Polyvagal Theory (Porges); HRV & vagal tone (Thayer & Lane).
