HPA Axis: Short-Term Help, Long-Term Harm

In this episode of Trauma Rewired, we explore autoimmune conditions through a nervous-system and psychoneuroimmunology lens—moving beyond the idea that the body is "attacking itself." Instead, we examine autoimmunity as an adaptive output of a system that has lived in chronic threat for too long.

Jennifer Wallace and Elisabeth Kristof unpack how immune response, emotional expression, boundaries, trauma history, and social stress intersect at the level of physiology. Drawing on research from ACEs, chronic inflammation, the HPA axis, the inflammatory reflex, and shame-based immune activation, they explain how the brain's predictions—rather than isolated biology—shape immune behavior.

You'll hear why autoimmune conditions disproportionately affect women and marginalized communities, how emotional suppression and boundary violations translate into inflammation, and why anger, shame, and safety are biological—not just psychological—processes. The episode closes with a grounded conversation on post-traumatic growth: what it means to live in partnership with the body, retrain predictions through sensory and interoceptive work, and expand resilience alongside medical care. This is an invitation to replace self-blame with curiosity—and to see regulation, expression, and safety as central to immune health.

• 00:00 – Intro: Autoimmune as protection, not self-attack

• 08:40 – Autoimmune, ACEs, gender, and nervous system prediction

• 21:05 – Chronic inflammation, HPA axis & the inflammatory reflex

• 35:20 – Boundaries, anger, shame & post-traumatic growth

• 52:00 – Closing reflections & integration

• Autoimmune responses can be understood as nervous-system outputs shaped by prediction and chronic threat.

• Early adversity, emotional suppression, and social stress significantly increase inflammatory load.

• Boundaries are physiological capacities rooted in interoception and proprioception—not just communication skills.

• Training safety, expression, and regulation can complement medical care and reduce flare frequency.
