The Life-Changing Power of Sunlight: Light as Nutrition, Near-Infrared Science & Human Health
Dave speaks with Dr. Nicholas Witton, a sleep medicine and light researcher, about the critical role of natural light, especially near-infrared (NIR) light, in human health.
Nicholas explains how we've shifted from living outdoors to spending over 90% of our time indoors under artificial light, particularly LEDs, which emit mainly blue light and lack the full spectrum, including the NIR wavelengths that make up over 50% of solar energy.
They explore how NIR light supports mitochondrial function, ATP production, and glucose regulation, with implications for metabolic health, sleep, mood, and…
