Beyond daily rhythms, longer cycles affect decision energy:
Seasonal Affective Patterns - Winter: Lower morning energy, protect afternoons - Spring: Natural energy boost, leverage mornings - Summer: Extended peak hours, watch for overcommitment - Fall: Energy decline, increase recovery time
Monthly Hormonal Patterns (for those who menstruate) - Days 1-5: Lower energy, avoid major decisions - Days 6-14: Rising energy, schedule important choices - Days 15-20: Peak decision-making capacity - Days 21-28: Declining energy, routine decisions only
Tracking these patterns prevents scheduling important decisions during predictable low points.
