Ultradian Rhythms
The 90-minute BRAC cycle aligns perfectly with 1:30 PM if you start deep work at 12:00 PM. Tracking this specific duration prevents cognitive burnout.
Post-Lunch Pivot
1:30 PM (13:30) typically marks the end of the "Post-Lunch Dip." It is the biological signal to switch from passive tasks (email) to active creation.
Meeting Psychology
Starting a meeting at 1:30 PM yields higher attendance than 1:00 PM. The specific offset creates a psychological "appointment urgency."
🧠 The Science of Timing

| Rest / Admin | 12:30 - 1:00 | Low-focus tasks, Email triage |
