The Hidden Link Between Light, Cancer, and Weight Gain | Dr. Martin Moore-Ede

Host Sarah Kleiner interviews Dr. Martin Moore-Ede, a Harvard-trained physician-scientist who helped identify the human circadian clock in the suprachiasmatic nucleus and showed humans are synchronized by light timing. They discuss how modern indoor living mimics shift work—dim days, blue-rich nights—and its links to disrupted sleep physiology, suppressed melatonin, metabolic effects, and increased risks including cancer and cardiovascular disease, citing a new study associating as little as 3 lux at night with measurable heart damage in 11,000 people. Moore-Ede explains why lux/lumens miss health-relevant wavelengths, the narrow circadian-sensitive blue band (~480 nm), and the importance of full-spectrum daylight (especially before 10 a.m.) and blue-free evenings. He highlights infrared’s…
