Why incandescent was better than modern LEDs

We obsess over food and supplements. Meanwhile, the light we live under every day is quietly wrecking our biology.

In this episode, I sit down with Matt Maruca, founder and CEO of Ra Optics, to discuss how artificial light, blue light, and disrupted circadian rhythm quietly impact energy, sleep, and long-term health. Matt shares how a years-long personal health journey led him to study circadian biology and the essential role light plays in human physiology.

We explore why modern indoor environments are so biologically mismatched, how LED lighting and screens affect mitochondrial health, and why sunlight is powerful but not something to mindlessly overdo. Matt also explains how light influences hormones, mental health, and recovery, and why most wellness conversations miss this entirely.

Beyond the science, we touch on Matt’s broader work teaching how to think differently about light exposure, health, and performance.

If you’re interested in biohacking, sleep optimization, blue light, or understanding why your nervous system feels constantly overstimulated, this episode will shift how you see your environment.
