## Items

- [Ultradian Rhythm 90-Minute Cycles](https://timetrack.works/es/items/ultradian-rhythm-90-minute-cycles) — Science-based productivity method using natural 90-minute biological cycles for focused work sessions. Based on ultradian rhythms, it optimizes cognitive performance through work-rest cycles aligned with body's natural patterns.
- [Circadian Rhythm Scheduling](https://timetrack.works/es/items/circadian-rhythm-scheduling) — Time management approach that schedules tasks according to your body's natural 24-hour biological clock, placing demanding cognitive work during peak alertness periods and lighter tasks during natural energy dips.
- [Neural Entrainment Music](https://timetrack.works/es/items/neural-entrainment-music) — Category of scientifically-designed audio that uses specific acoustic features to influence brainwave patterns and enhance focus, productivity, or relaxation. Used by services like Brain.fm and based on neuroscience research.
- [Ultradian Rhythms](https://timetrack.works/es/items/ultradian-rhythms) — Natural 90-120 minute cycles of alertness and energy that repeat throughout the day, forming the scientific basis for productivity techniques like 90-minute focus sessions and explaining why our concentration naturally waxes and wanes.
- [Ultradian Rhythm 90-Minute Focus Sessions](https://timetrack.works/es/items/ultradian-rhythm-90-minute-focus-sessions) — Productivity technique based on natural 90-120 minute biological cycles, maximizing focus during peak performance periods and scheduling recovery breaks.
- [Peak Performance Timing](https://timetrack.works/es/items/peak-performance-timing) — Science-based approach to scheduling tasks based on daily cognitive performance patterns. Uses research on circadian rhythms and ultradian cycles to optimize when different types of work are performed.
- [Ultradian Rhythm Method](https://timetrack.works/es/items/ultradian-rhythm) — Science-based productivity approach using natural 90-120 minute body cycles discovered by Nathaniel Kleitman. Research shows 40% higher productivity when aligning work with these cycles, with breaks after each 90-minute block.
