BRS6(FM3) - Autonomic Balance & Vagal Recovery Capacity
Functional control of sympathetic–parasympathetic balance, vagal recovery, and physiological downshifting after stress or cognitive demand.
Functional Role
↑ vagal recovery; ↑ HRV context; ↓ chronic sympathetic load
Underlying Mechanisms and Requirements
PMs (Primary Mechanisms)
- BRS6(PM5) - Sympathetic Activation & Parasympathetic Recovery
- BRS6(PM6) - Vagal Tone / HRV Regulation
KCs (Key Constraints)
Cross-BRS Links
- BRS5(FM3) — Gut–Vagal Neuromodulation & ENS Signalling
- BRS3(FM1) — Inflammatory Tone Regulation
Interventions
Diet
omega-3-rich foods → HRV support context; magnesium-rich foods → neuromuscular relaxation support; fermented foods plus fibre → gut-vagal signalling support; stable meal composition → reduced sympathetic-reactive swings
Lifestyle
slow breathing and vagal training practices → increased parasympathetic tone; recovery-focused exercise dosing → improved autonomic flexibility; sleep continuity and stress downshifting routines → reduced chronic sympathetic load
Outputs / Functional Effects
↑ vagal recovery; ↑ HRV context; ↓ chronic sympathetic load

Scoring Interpretation
Low support and high support interpretation should be defined in narrative only; no formulas are included in this test generation.
Evidence Base
- Evidence Type: Human + mechanistic [1] [2] [3]
- Evidence Notes: Central lifestyle-crossing FM. Diet supports the system but breathing, recovery, and stress practices are often dominant. [1] [2] [3]
