Understand light.
Perform better.
The education centre for endurance athletes on sun, UV, circadian rhythm, and photobiomodulation. Start with the fundamentals, then follow the applied protocols.
The curriculum
Six subject areas, each with fundamentals, applied protocols, and a reading list.
How ultraviolet radiation reaches you, what it does to skin and DNA, and how to dose it for endurance sport.
Light as the master signal for sleep, hormones, and next-day performance. Timing, intensity, spectrum.
Photobiomodulation for recovery, mitochondria, and inflammation. What the evidence says, what it doesn't.
Blue light, glare, sunglasses, and the ocular pathway that drives your circadian clock.
Applied light protocols for cyclists, runners, triathletes. Training, racing, travelling.
Sunscreen, sweat, thermoregulation, and repair. How to protect skin without cooking performance.
Getting started
Four short reads. About twenty minutes. You'll leave with a working model of how light shapes performance.
- 01What light actually isPhotons, wavelengths, and why the units matter.
- 02The three bands that matterUV, visible, and infrared — what each one does to a training body.
- 03The circadian pathwayHow light in the eye becomes hormones, temperature, and readiness.
- 04Dose, timing, spectrumThe three levers you actually control.
