What if the single most overlooked “nutrient” for your brain, mood, and longevity… isn’t a supplement at all, but light? In this episode, Professor & Podcaster John Torrens sits down with Tom Kerber, CEO & Founder of SunPowerLED, to unpack four decades of working with light, from early blue LED dental devices to cutting‑edge red and near‑infrared therapy. Together, they explore how different wavelengths interact with your eyes, skin, mitochondria, and even your brain through the skull and how you can use that knowledge to feel and perform better every day. You’ll hear how our modern, indoor, LED‑lit lifestyle has quietly created a light‑deprived biology, what that means for sleep, mood, and cellular health, and practical ways to reclaim healthier light exposure without turning your life upside down. In this episode, you’ll learn:• Why we’re “light malnourished” indoors and how that impacts circadian rhythm, mood, and cognitive function• The difference between blue, red, and near‑infrared light and why wavelength and depth of penetration matter• How red and near‑infrared support mitochondria, nitric oxide production, blood flow, and faster healing• Practical tips to use morning light, blue‑blocking, and targeted red light in your daily routine• When to be cautious: Botox, sensitive nervous systems, and dosing strategies for brain and neurological issues If you’re serious about longevity, performance, and nervous system health, this conversation will change the way you think about the light you live in.cTune in!
