Neurological Sleep Architecture & Ultradian Rhythm Alignment

Preventing post-sleep grogginess requires aligning waking times with the brain's natural sleep patterns. This sleep tracker schedules rest intervals around standard 90-minute neurological cycles to prevent waking up during deep sleep phases.

Methodology: The system maps forward and reverse time pathways based on 90-minute cycles. It factors in a standard 14-minute sleep latency offset to ensure the user wakes up at the optimal point in their sleep cycle.
