How Does Light Exposure Control Your Hormones?

In this episode, hosts Emma Sullivan and David Park explore how natural light exposure—specifically, outdoor light hitting your eyes within the first hour of waking—acts as a biological reset button for your hormones, sleep, and mood by signaling your brain's master clock. They break down the science of intrinsically photosensitive retinal ganglion cells and how morning light regulates everything from cortisol timing to melatonin production, plus why this matters even more as you age. You'll walk away with a simple, evidence-backed practice: five to thirty minutes of outdoor light exposure before caffeine or screens, and an understanding of why this low-cost habit is one of the highest-leverage interventions for circadian health.Follow The Wellness Rhythm Show:  ▶️ YouTube: https://www.youtube.com/@TheWellnessRhythmShow  📖 Newsletter: https://thewellnessrhythmshow.substack.com  Powered by VoxCrea.AI
