126. Blue Light, Melatonin & The Modern Sleep Crisis with Sam Nahna

Blue light is everywhere… but most people have no idea what it’s actually doing to their bodies.In this episode of the Everyday Epigenetics: Raw. Real. Relatable podcast, Susan sits down with Sam Nahna from Block Blue Light to unpack the real science behind blue light exposure, circadian rhythms, melatonin production, sleep disruption, and why modern lighting may be affecting your health more than you realize.From doom scrolling at night to overhead LED lights, Sam explains how constant exposure to artificial blue light impacts sleep quality, recovery, focus, mood, and long-term wellbeing. The conversation dives into the differences between clear, yellow, amber, and red blue light blocking lenses, why cheap “blue light glasses” often don’t work, and how to create a more sleep-supportive environment without completely disconnecting from modern life.Susan also shares her own experience using red light glasses and how dramatically they’ve helped her wind down, improve sleep quality, and support her natural rhythms during longer summer evenings.This episode is packed with practical, easy-to-understand information for anyone struggling with sleep, screen fatigue, nighttime stimulation, or feeling “wired but tired” at the end of the day.Key Takeaways:What blue light actually is and how it affects the body and brainWhy artificial light exposure at night disrupts melatonin and circadian rhythmsThe difference between clear, yellow, amber, and red blue light blocking lensesHow poor sleep impacts recovery, mental health, hormones, and overall healthSimple ways to reduce blue light exposure and create a healthier nighttime environmentConnect with Sam Nahna + Block Blue Light:Website: https://www.blockbluelight.com/Instagram: https://www.instagram.com/blockbluelight_official/Learn more about Sam Nahna:At BlueBlockLight, we create research-backed products designed to support health, circadian biology, and light-conscious living.Sam has been with the company since its early stages and has become a leading product expert in the field of blue light mitigation and blue light blocking technology.
