Summary
Matt Maruca, founder of Ra Optics and the Light Diet joins me to talk about the healing power of sunlight and the dangers of artificial light. He shares practical tips that one can integrate when traveling across time zones. He talks about why he likes to eat his biggest meal in the middle of the day, the specific problem with LED lighting, why the smart phone slow motion feature is not accurate to prove flicker rate of healthy bulbs, what the color rendering index means, why we want our indoor lighting to be at eye level or lower at night, his thoughts on Starlink and X, ultraviolet light therapy, and more.

Key Moments
Cheap blue blockers use deceptive marketing and are not real solutions
Matt Blackburn introduces Matt Maruca, who explains how inexpensive blue light blocking glasses use deceptive marketing claims and fail to actually block the harmful wavelengths that disrupt circadian rhythm and mitochondrial function.
"how cheap blue blockers are using deceptive marketing and aren't a real solution to the real problem"
Overhead lights versus eye-level lighting and circadian disruption
Maruca discusses the importance of light positioning, explaining that overhead lights are more disruptive to circadian biology than lights placed at eye level or below, and that smartphone slow-motion video can reveal harmful flicker in bulbs.
"circadian light bulbs on the market. He said that the slow-mo test to see the flicker on your smartp"
From gut issues to light science through Jack Kruse
Matt Maruca shares his origin story of childhood gut issues and allergies that conventional medicine failed to resolve, leading him through paleo nutrition to Jack Kruse's work on light, mitochondria, and quantum biology.
"As a teenager or even younger, as a young kid, I was having gut issues, allergi"
