Light Diet - Part 2: How Modern Life Is Wrecking Your Health (And What to Do About It) with Roderick Lambert

The Animal Based Dad Podcast

Is your lifestyle silently sabotaging your health? In this episode, Roderick and Ricky explore how modern indoor living, blue light exposure, and sunscreen overuse are contributing to a growing "light deficiency epidemic." They reveal how our natural circadian rhythms, metabolic health, and even skin resilience are being disrupted by artificial environments and digital habits.

You’ll learn:

• Why natural sunlight exposure is essential for mitochondrial and hormonal health.
• How blue light from screens and LEDs impacts sleep, insulin sensitivity, and mood.
• The surprising truth about sunscreen, UV light, and cancer myths.
• Practical strategies to optimize light exposure for better energy, immunity, and longevity.
• Tools like infrared panels, light-tracking apps, and full-spectrum bulbs to biohack your environment.

Perfect for health seekers, wellness enthusiasts, and biohackers looking to reclaim their vitality by syncing with the natural light-dark cycle.
