The sympathetic nervous system (SNS) is the "fight or flight" branch of the autonomic nervous system. It mobilizes the body for action — increasing heart rate, redirecting blood flow, and releasing stress hormones.
Key Effects
- •Increased heart rate and blood pressure
- •Redirected blood flow to muscles
- •Cortisol and adrenaline release
- •Suppressed digestion
- •Heightened alertness
In ONDA Life
Chronic sympathetic activation (stress) keeps the body in deficit mode. Level 1 practices help restore balance by activating the parasympathetic system, allowing the sympathetic branch to return to baseline when not needed.
Scientific Basis
Built on: Polyvagal Theory (Porges); Psychoneuroimmunology (Ader & Cohen); neuroplasticity research.
