BRS6(FM2) - HPA Axis Rhythm & Cortisol Regulation
Functional control of cortisol rhythm, circadian timing, and stress-hormone regulation across waking, feeding, and recovery cycles.
Functional Role
↑ cortisol rhythm stability; ↑ morning activation; ↓ evening stress-hormone drift
Underlying Mechanisms and Requirements
PMs (Primary Mechanisms)
KCs (Key Constraints)
- BRS6(KC1) - Glucose / Energy Substrate Availability
- BRS6(KC2) - Stress-Response Micronutrient Sufficiency
Cross-BRS Links
- BRS1(PM1) — Dopaminergic Signalling
- BRS4(FM1) — Cellular Bioenergetics
Interventions
Diet
regular protein-rich breakfast → morning energy/catecholamine support; consistent meal timing with early-day energy loading → circadian metabolic entrainment; reduced late-night eating → lower circadian misalignment pressure
Lifestyle
morning daylight exposure → circadian alignment; reduced evening light and stable sleep-wake timing → improved cortisol amplitude and phase alignment; stress regulation practices → reduced evening cortisol spillover
Outputs / Functional Effects
↑ cortisol rhythm stability; ↑ morning activation; ↓ evening stress-hormone drift

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: Lifestyle-dominant FM with strong diet timing support. Avoid overclaiming food-only control of cortisol. [1] [2] [3]
