Light is something we often take for granted. We flip a switch, our rooms brighten, and we move on with our day. But what if the light we’re exposed to is impacting our sleep, health, and overall longevity? Dr. Martin Moore-Ede, a pioneer in circadian science, joins me on A Productive Conversation to discuss the powerful role light plays in our lives. His latest book, The Light Doctor: Using Light to Boost Health, Improve Sleep, and Live Longer, dives deep into how modern lighting affects our bodies and what we can do to make healthier choices.

In this episode, we explore the unseen effects of artificial lighting, how night owls (like me) can optimize their routines, and why the right type of light exposure is as critical as nutrition and exercise. If you’ve ever wondered why you feel wired at night, sluggish in the morning, or just can’t seem to get restful sleep, this conversation will shine a light—literally—on what might be going on.
