#270 Light Is Information, Not Just Illumination: How Your Light Environment Controls Energy, Sleep & Longevity | Roudy Nassif @Vivarays

What if the reason you feel tired, foggy, and wired, despite eating clean and training hard, is the light you're sitting under right now?

Engineer and VivaRays founder Roudy Nassif explains why light is information, not just illumination, and how your light environment quietly controls energy, sleep, mood, and longevity. He shares the science of human photosynthesis, melatonin as the body's strongest antioxidant, why blue light isn't the villain, and the exact protocol he used to reverse his own ADHD, depression, and chronic fatigue.
