Peak-Trough-Recovery Model
Time management framework based on daily energy patterns, scheduling analytical work during morning peak, administrative tasks during afternoon trough, and creative work during evening recovery period.

Overview
The Peak-Trough-Recovery Model structures daily work based on natural energy fluctuations. Popularized by Daniel Pink in "When: The Scientific Secrets of Perfect Timing," it optimizes task scheduling for maximum productivity and well-being.
The Three Phases
Peak (Morning)
- Timing: First 2-4 hours after waking
- Energy: Highest cognitive capacity
- Best for: Analytical work, strategic thinking, important decisions
- Examples: Complex problem-solving, writing, coding, financial analysis
Trough (Early-Mid Afternoon)
- Timing: ~7 hours after waking (typically 2-4pm)
- Energy: Lowest point of day
- Best for: Administrative tasks, routine work
- Examples: Email, filing, data entry, meetings (if necessary)
Recovery (Late Afternoon-Evening)
- Timing: After trough, before sleep
- Energy: Moderate, different quality than peak
- Best for: Creative thinking, brainstorming, iterative work
- Examples: Ideation, collaboration, less structured tasks
Application Strategies
Schedule Matching
- List all daily tasks
- Categorize by type (analytical, administrative, creative)
- Map to appropriate phase
- Protect peak time vigilantly
Common Patterns
- 9am-12pm: Deep work, important projects
- 12pm-2pm: Lunch, lighter tasks, meetings
- 2pm-4pm: Administrative work, email
- 4pm-6pm: Collaborative work, planning
Individual Variations
Chronotypes
- Larks (Morning People): Earlier peak, earlier trough
- Owls (Night People): Later peak, later trough
- Third Birds (Majority): Standard pattern
Adjustments
- Track personal energy patterns
- Experiment with timing
- Adjust for age (peaks shift earlier with age)
- Account for sleep quality
Benefits
- Higher quality work output
- Better decision-making
- Reduced mental fatigue
- Improved work-life balance
- More sustainable productivity
Time Tracking Integration
- Log energy levels with time entries
- Track output quality by time of day
- Identify personal peak/trough/recovery times
- Optimize schedule based on data
- Correlate task type with performance
