Is it true that increased vagal tone is associated with greater parasympathetic nervous system activity and cardiovascular health?

Yes. Increased vagal tone corresponds to enhanced parasympathetic activity, which promotes restorative cardiovascular regulation and protects against autonomic imbalance and disease.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The retrieved papers consistently support the physiological understanding that vagal tone reflects parasympathetic nervous system activity and that maintaining or enhancing vagal/parasympathetic function is beneficial for cardiovascular health and resilience.

Mental health consequences of early life stress in children - The autonomic nervous system as a potential target for early detection and intervention?

2025

Highlights that parasympathetic (vagal) activity is protective and that autonomic imbalance characterized by vagal underactivity is linked to cardiovascular disease.
