BRS6(PM7) - Vagal Tone / HRV Regulation
1. Definition
Regulation of vagal tone and heart-rate-variability-related recovery capacity.
2. Mechanistic Basis
↑ vagal tone context; ↑ HRV; ↑ recovery signalling
3. Dependencies
3.1 KCs (Key Constraints)
3.2 Optional BRSX Modifiers
- None listed
3.3 Co-factors
- omega-3
- magnesium
4. Dietary Modulation
breathwork / meditation → HRV support; omega-3-rich foods → HRV context; fibre/fermented foods → gut–vagal support; sleep regularity → recovery physiology
5. Functional Outputs (Directional Effects)
↑ vagal tone context; ↑ HRV; ↑ recovery signalling
6. System Integration
Integrated within BRS6(FM3) as an autonomic recovery mechanism linking vagal signalling to stress-downshift capacity.
7. Key Insight
PM6 reflects whether recovery signalling is physiologically available after demand, with HRV context as a practical readout of this regulation axis.
8. Functional Mechanism Ownership
- BRS6(FM3)
9. Intervention Dominance
- Lifestyle-Dominant
10. Constraints and Failure Modes

11. Notes
- Evidence Type: Human + mechanistic
- Evidence Notes: Crosses BRS5 strongly; kept in BRS6 because autonomic regulation is the control target.
