## 4. Biochemical Synergies & Evidence Strengths
- **Anchor Elements (Highest Evidence Pillars)**: morning_sunlight, cold_water_immersion, zone_2_cardio, cyclic_sighing
- **Detected Biological Redundancies**: [object Object]
- **Identified Longevity Gaps**: Dedicated bone density heavy axial loading

### ⚠️ Critical Stack Conflicts & Separation Advice
- **morning_sunlight vs blue_light_blocking**: Wearing tinted or UV-blocking glasses during the morning photon window prevents melanopsin retinal ganglion cell activation.
- **resistance_training vs cold_water_immersion**: Cold water immersion <4 hours post-lifting blunts p70S6K and muscular hypertrophy.
