In this episode of The Commune Podcast, Jeff Krasno explores how our relationship with light — both natural and artificial — shapes every system in the body. From sleep and mood to metabolism and longevity, light governs our circadian rhythm and hormonal balance in profound ways.

Jeff breaks down the science of blue light, infrared radiation, and vitamin D synthesis, revealing how morning sunlight, time in nature, and even darkness play essential roles in human health. You’ll also learn simple, evidence-based protocols for aligning your body’s natural clock, improving sleep quality, and reducing stress — by returning to the rhythms our ancestors lived by.
