In this episode, Dr. Jockers dives deep with Dr. Sara Pugh into how light influences your mitochondria, hormones, and inflammation in ways food alone never could. You'll hear how sunrise sets your body clock, why sunset prepares your system for rest, and how the balance of light and darkness fuels cellular health.
You'll learn how artificial blue light at night can disrupt cortisol, blood sugar, and cravings, and why the wrong kind of light exposure can be just as damaging as poor nutrition. Discover why your mitochondria respond to light as much as to food and how this hidden factor impacts your mood, metabolism, and resilience.
We also explore practical steps—like grounding, sauna use, and cold therapy—that boost your energy and improve sleep. Along the way, you'll find out why sunscreen and sunglasses may do more harm than good, and how structured water and omega-3 fats fit into the bigger picture of cellular repair.
