112 - The Sun, Circadian Rhythm & Quantum Biology: Why Light May Be the Missing Piece with Rachel Maurice MD

Is the sun really as dangerous as we have been led to believe?

I've always questioned this and have never chosen to shun the sun as a result.

What if some of the most important inputs to your health aren’t found in a bottle—but in sunlight, darkness, and the timing of your daily life?

In this episode, Rachel Maurice returns to continue the conversation from Episode 106 and dives deep into circadian biology, light as a biological signal, mitochondrial function, structured water, melanin, sleep, and the fundamentals of quantum biology.

Rachel shares her own experience with chronic fatigue and sleep struggles after leaving the medical system in 2021—and how two simple changes, morning sunlight and blue-light blocking at sunset, dramatically changed her energy and sleep within weeks.

We also explore why modern indoor environments may be disrupting the signals our biology evolved around, why when you get light matters, the importance of darkness at night, and why getting the fundamentals right may matter more than constantly searching for the next supplement or health hack.
