Think 8 hours of sleep is enough? Think again. I used to think I had a sleep issue—turns out, it was a light issue. In this video, I break down why light exposure, not just sleep duration, controls your circadian rhythm, energy, and recovery. From morning sunlight to blocking blue light at night, I’ll show you how to biohack your environment for deeper sleep, better performance, and real recovery. Your biology is programmable—let’s upgrade it.
