The Power Of Circadian Rhythms
- Circadian rhythms govern many of our biological processes on a ~24-hour cycle.
- We often ignore these natural daily rhythms despite their strong influence.
Ultradian 90-Minute Cycles
- Ultradian rhythms operate at a higher frequency than circadians and repeat roughly every 90 minutes.
- The term "ultradian" was coined in the 1960s to describe these shorter performance cycles.
Performance Peaks Last 90 Minutes
- Research shows our upper threshold for peak performance in a single burst is about 90 minutes.
- Working beyond that without breaks causes endurance stress, reducing performance and risking chronic fatigue.
