Unpacking psychological injury

What actually happens in our brains and bodies when stress crosses the line into psychological harm? In this episode of Relational Practice: A Social Work Podcast, hosts Dr. Jodie Park and Rose Mackey take a deep dive into the hidden mechanics of trauma, unpacking how chronic stress reshapes the mind, body, and daily relationships. Jodie and Rose blend neurobiology, developmental insights, and clinical wisdom to help practitioners move past surface symptoms. In this episode, we unpack: The Neurobiology of Threat: How an overactive amygdala, downregulated prefrontal cortex, and shrinking hippocampus keep the nervous system stuck in "survival mode". Age & Presentation: Why trauma looks like "high-functioning burnout" or physical pain in adults, but shows up as regression, self-blame, or behavioural disruptions in children. The Multi-System Ripple Effect: Using Dan Siegel's Window of Tolerance to understand emotional dysregulation, the shame loop, betrayal trauma, and why hyper-independence is often a trauma response in disguise. Practical & Safe Interventions: Why proactive screening matters, why single-session psychological debriefing can cause harm, and how first-line therapies like TF-CBT and EMDR foster genuine recovery. Whether you are a social worker, allied health professional, educator, or student, this episode offers a grounding, trauma-informed perspective on supporting survivors without burning out yourself.
