Episode Details

Stress is not just a feeling — it's a biological force that can directly influence your immune system.

In this powerful episode of The GoodLife in Health and Wellness, Dr. Kate Duncan dives deep into the connection between trauma, cortisol dysregulation, and autoimmune flare-ups. If you've ever noticed your symptoms worsen during periods of emotional stress, poor sleep, or burnout, this episode will help you understand why.

We explore how the HPA axis becomes dysregulated, how chronic fight-or-flight activation drives inflammation, how stress damages the gut barrier, and why unresolved trauma can alter immune signaling at a cellular level. You'll learn how cortisol acts as both regulator and disruptor, how sympathetic dominance keeps the immune system on high alert, and what it truly means to retrain your nervous system for resilience.

Autoimmune disease is not simply a genetic lottery. It's often the result of immune overload, gut dysfunction, environmental triggers, and long-standing stress patterns. The good news? Your nervous system is trainable, and healing becomes possible when safety is restored at the cellular level.

If you're living with Hashimoto's, rheumatoid arthritis, lupus, psoriasis, or unexplained inflammatory symptoms, this episode will help you connect the dots between stress and your immune health — and give you practical direction for moving forward.
