- Professional Assessment
- Baseline indicates moderate stress-disrupted sleep with prolonged latency and reduced SWS. Typical of chronic HPA-axis activation. Week-one data shows recalibration toward parasympathetic dominance with architecture improvement but minimal duration change. Results align with hypothalamic modulation rather than direct sedation.
