Episode Description from the Publisher

Metabolic syndrome, long-haul syndromes, hypersensitivity, and autoimmunity are four ways the immune system adapts to a nervous system living in fear. Each one is the immune system adapting to a fear-driven nervous system. These are adaptations. The body is doing what bodies do. In this solo episode, Dr. Aimie walks through all four immune adaptive patterns. The fear pattern behind each one. What your diagnosis is actually telling you. And why hope lives in a simple fact: most immune cells turn over every three days. She also shares her own experience with all four. This is also her own story. Her work in repairing the Biology of Trauma®  started here. ➡️ Full show notes: https://www.biologyoftrauma.com/post/what-fear-does-to-your-immune-system-biology-of-trauma In This Episode You'll Learn: [01:00] Why our nervous system always adapts (and our immune system follows) [03:00] The first immune adaptive pattern: metabolic syndrome [06:00] What the lab markers actually point to (it lives upstream) [08:00] The second immune adaptive pattern: long-haul syndromes [11:00] Pre-existing nervous system state matters more than the exposure [13:00] Dr. Aimie's college mono-like illness and the decade-long pattern [15:00] The third immune adaptive pattern: hypersensitivity [18:00] Why some people don't know they're hypersensitive [21:00] The three-day window: how fast the immune system can shift [22:00] What changed in three days with adopted children [24:00] The fourth immune adaptive pattern: autoimmunity [27:00] Fear that turned inward as anger (and why) [29:00] Having all four patterns: Dr. Aimie's own story Resources/Guides: Read Chapter 10 of The Biology of Trauma —The Biology of Trauma book goes into all four immune adaptive patterns and the shared root in nervous system dysregulation in chapter 10. ➡️ Full show notes for resources and links: https://www.biologyoftrauma.com/post/what-fear-does-to-your-immune-system-biology-of-trauma
