In this episode, I’m joined by Dr. Martin Moore-Ede, a Harvard-trained physician and pioneering circadian scientist, to explain how something as familiar as modern lighting is silently wreaking havoc on your health. From blue light's effects on metabolism and sleep to how most homes and workplaces are wired for illness, this conversation pulls back the curtain on a hidden environmental health crisis.
Dr. Martin Moore-Ede shares decades of research, including shocking studies on how artificial light can induce pre-diabetic states within hours, as well as insights on how to live longer, sleep better, and protect your body from the wrong light at the wrong time.
Learn how to audit your own light environment and take practical steps to protect your circadian rhythm, improve healthspan, and finally understand why your body feels “off," even when you’re doing everything else right.
