Breaking the Cycle of Stress: How Your Mind Rewires Your Immune System

#35: 2025’s Nobel Prize in Physiology/Medicine puts regulatory T cells (Tregs) and the FOXP3 gene center stage—and in this episode, Christian Fowler joins host Aaron Fournier to connect that discovery to everyday tools that lower stress and inflammation. We break down how IL-10 from Tregs crosses the blood–brain barrier to reduce neuroinflammation, why chronic stress down-regulates FOXP3 (and Tregs), and how mindset, vagal tone, sleep, sunlight, movement, and targeted sound (like 528 Hz) can help flip you from fight-or-flight into rest-and-digest. We also discuss studies showing Treg expansion reduces anxiety-like behavior, brief/acute stress boosts dopamine and learning, and chronic stress suppresses immune tolerance—plus practical “wins” (make your bed, humming, Mindful Intentions) that build resilience daily. 🔬 Studies & Resources Mentioned: 1.
