Biometric-Driven Work Cycles

Based on the concept of ultradian rhythms, this item suggests tracking heart rate variability (HRV) or using simple focus tracking to identify your "Biological Prime Time." Instead of the standard Pomodoro (25/5), this contributor shares a system of 90-minute sprints followed by 20-minute active recovery (walking/stretching). In the Hub, members can share their data logs to see if there are common patterns across different time zones or professions. It’s about working with your body, not against it, to prevent burnout.
