Your body isn’t running on random signals. It’s operating on a tightly controlled internal clock that influences nearly every system, from hormones and metabolism to sleep, mood, and cellular repair. When that clock is off, things start to break down in ways most people don’t even realize.

In this episode, we dive into the real science of circadian biology and why light, especially sunlight, is one of the most powerful inputs shaping your health. Our guest, Zaid K Dahhaj, cuts through the noise and challenges the common narratives around sun exposure, unpacking what’s actually happening at a biological level versus what you’ve been told to believe.

This conversation goes beyond surface-level advice and gets into how your environment, habits, and daily rhythms are either supporting your physiology or quietly working against it.

Zaid is a Circadian Biology Educator, Host of the popular substack "The Circadian Classroom," teaching people how light, time, and environment shape every system in the body. His work bridges molecular biology with practical lifestyle design rooted in sunlight and ancestral rhythm.
