#32 - Is Modern Lighting Disrupting Your Metabolism? Mitochondria & Photometabolism With Prof Bob Fosbury

Astrophysicist Professor Bob Fosbury joins Dr Sara Pugh to explain photometabolism — the role of light, and especially near-infrared, in mitochondrial health, diabetes, obesity and ageing. We look at how modern lighting starves us of the infrared our mitochondria evolved to expect, why white LEDs are not the neutral choice they appear to be, and what incandescent bulbs, red light, sunlight, cold exposure and forest bathing actually do at the level of the electron transport chain. Bob takes us through water vibrations as an intermediary in electron transport and gives practical, actionable lifestyle suggestions.    Metabolism in the Solar Photon Field — paper by Bob Fosbury, Glen Jeffery, Scott Zimmerman & Roger Seheult 📰👉 https://www.biorxiv.org/content/10.64898/2026.08.11.744135v1 Substack post 'Why Food Is Only The Beginning of Metabolism: Store Fat Or Use It?' 📰👉 https://drsarapugh.substack.com/p/why-food-is-only-the-beginning-of-d86 Retreats In France 2026 — Learn More & Download The Brochures 👇👇 https://busysuperhuman.com/retreats-events/ To book on a retreat or ask questions, book a 30 min Zoom call 👉 https://calendly.com/sara-pugh/enquiry-call-to-retreat Sponsored by Litewater Scientific Deuterium Depleted Water, Deuterium tests, Hydrogen Water Bottles, Quinton Minerals, Hydrogen Tablets Click The Link Below For 10 %OFF https://bit.ly/4aN9zdI Or Use Code: DRSARA https://www.drinklitewater.com/ New Content 🌞 Quantum Starter Kit - 50 Slides - 5 Videos 👇👇👇 https://courses.busysuperhuman.com/the-quantum-starter-kit 🍚 Light, Water, Charge & Sugar eBook - Prevent Insulin Resistance.

Infrared light acts as a lubricant for the mitochondrial engine rather than as a fuel. Water vibrations work as an intermediary in electron transport, and Marcus theory explains the barrier crossing involved. Gentle, broad-spectrum infrared — incandescent bulbs, firelight, sunlight through leaves — matters more than intensity. Natural environments, forest bathing and cold exposure act on the same metabolic machinery as light does.
