Biohacker's PodcastBecome a healthspan optimizer and live longer, eat better, recover faster, perform better, and get more done. Author: Biohacker's Podcast
Welcome to the Biohacker's Podcast, where we explore the intersection of technology, nature, and self-development. As biohackers, we view our bodies as complex systems that can be analyzed and probed in order to gain a deeper understanding of ourselves. Through controlled experimentation, we pursue ways to optimize our physical and mental health, increase our longevity, and enhance our cognitive abilities. Join us as we delve into the latest research and innovative techniques in biohacking, while also exploring the natural world and how it can aid in our self-development. Produced by Biohacker Center, the leading healthspan optimization company focused on bringing you the world's best content, supplements, technologies, courses, and events to help you champion healthy habits, prolong your healthspan, and lead a productive life.

The Science of Light with Matt Maruca
Episode 73
Friday, 19 December, 2025
In this episode of the Biohacker's Podcast, Teemu Arina speaks with Matt Maruca, founder and CEO of Ra Optics, to examine the critical role light plays in human biology.Matt reframes light as a primary biological input that regulates circadian rhythm, hormone production, mitochondrial efficiency, and sleep quality. He explains how excessive exposure to artificial blue light (especially after sunset!) disrupts melatonin release and contributes to metabolic dysfunction, poor recovery, and chronic fatigue. Ra Optics was founded to address these challenges through scientifically engineered eyewear that selectively filters harmful wavelengths while preserving beneficial light.The discussion moves beyond blue light fear-mongering into practical circadian strategy. Matt emphasizes the importance of bright, full-spectrum light exposure during the day to anchor biological timing, while advocating warm, low-intensity lighting in the evening to support sleep. He highlights the role of red and near-infrared light in mitochondrial energy production and recovery, and cautions against low-quality lenses that distort vision or block indiscriminately.Looking forward, Matt envisions a future where personalized light environments - integrated with sleep and performance data - become central to health optimization. The episode concludes with a shared message: improving light hygiene is one of the highest-leverage, lowest-effort interventions available in modern biohacking.Learn more about Ra Optics at https://raoptics.com and follow Matt on Instagram: @thelightdiet!This conversation was recorded in October 2025.Check https://hololifesummit.com for upcoming events & tickets!
