Guest: Forrest Smith — serial founder bringing clinic-grade photobiomodulation to a safe, wearable form factor. Theme: Why dose and delivery matter more than raw wattage for red light therapy. Key takeaways Wavelengths that work: Deep red 660 nm (blood flow, NO release, shallow penetration) + 808 nm near-IR (deeper tissues/joints).Mechanisms: Hemoglobin photodissociates NO → vasodilation + better O₂ delivery; mitochondria’s cytochrome c oxidase bottleneck relieved → higher ATP output; downst...
