39: The Healing Power of Nature: Nervous System, Sunlight & Immune Regulation

Nature is free, accessible, and backed by a growing body of science — but for people managing autoimmune disease, it's not just a nice-to-have. In this episode, Jaime and Marie-Noelle explore the specific biological mechanisms that make nature exposure a meaningful part of your healing protocol. From the nervous system-calming effects of forest bathing to the way morning sunlight anchors your immune function, this conversation bridges the science and the practical in a way that's genuinely actionable, wherever you are and however you're feeling. What You'll Learn in This Episode Why the HPA axis is uniquely disrupted in autoimmune disease — and why that matters for your daily habits How chronic sympathetic activation suppresses immune repair while amplifying inflammation The UC Berkeley research on awe and its measurable anti-inflammatory effects What Shinrin-yoku (forest bathing) is and the remarkable NK cell findings from Japanese and South Korean studies Why you don't need access to a forest to get the nervous system benefits of nature How your circadian rhythm governs immune function — and which autoimmune conditions are most affected by circadian disruption The cortisol awakening response: what it is, why morning light triggers it, and what happens when it's blunted Why sunlight and vitamin D supplements are not the same thing How artificial light at night disrupts melatonin — and why melatonin is far more than a sleep hormone Simple, low-barrier practices you can start this week, even during a flare Resources & Links The Awe & Cytokines Study (UC Berkeley / Dacher Keltner) Stellar, J.E. et al.
