What if light is one of the most important signals controlling your biology?
In this episode, Roudy Nassif, founder of VivaRays, explains how natural light, artificial blue light, darkness, mitochondria, circadian rhythms, dopamine, sleep, and brain health are interconnected.
We explore the idea that light acts as biological information, why sunlight and darkness are important signals for human biology, and how artificial light exposure at the wrong time may disrupt circadian rhythms, sleep, hormones, energy, and dopamine regulation.
Roudy also shares his personal experience transforming his energy, focus, and mental health by changing his light environment, before explaining the role of blue light blocking glasses in modern environments filled with artificial light.
The conversation explores the connection between light and mitochondrial health, circadian biology, brain function, dopamine, melatonin, sleep, and overall wellbeing—and why the daily cycle of natural light and darkness is an overlooked part of modern health.
