- Acute Sleep Architecture
- 14–21 days
- Daily (evening)
- Delta wave amplitude, sleep latency, REM distribution studies
- 14 days minimum
- Optimal for studies prioritizing rapid establishment of measurable sleep parameter changes with minimal confounding variables
- Chronic Adaptation Protocol
- 28–35 days
- Daily or 5x weekly
- HPA axis response, cortisol patterns, immune markers linked to sleep quality
- 21–28 days minimum
- Required when measuring secondary physiological responses that emerge only after sustained sleep architecture improvement
- Intermittent Dosing Model
- 21–28 days
- 3x weekly (Mon/Wed/Fri)
- Long-term homeostatic adaptation without continuous receptor occupation
- 14–21 days minimum
- Extends total study duration but may reduce receptor desensitization risk in extended observation protocols
- Dose-Response Study
- 7–10 days per dose level
- Daily within each phase
- Establishing minimum effective dose and ceiling dose parameters
- 14 days between dose levels
- Short cycle per dose justified only when measuring acute effects; secondary endpoints require standard 14+ day cycles
