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
