The fight response is often misunderstood as a personality flaw, but it’s actually a deeply wired survival adaptation shaped by past experiences and trauma. In this episode of Trauma Rewired, we explore the difference between healthy, time-bound anger and the chronic fight state, how they’re created in the brain and body, and why learning to process anger is essential for emotional safety and healthy connection.

You’ll learn how the amygdala, hypothalamus, periaqueductal gray, insular cortex, and prefrontal cortex interact during a fight response, and how trauma can train the brain to see threat everywhere. We break down the health consequences of chronic fight, the relational patterns it creates, and why suppression of anger doesn’t make it go away — it stores it in the body.

From personal stories to neuroscience, this conversation offers tools to recognize the signals of fight mode, regulate your state, and reclaim anger as a clarifying force for setting boundaries and protecting what matters — without living in constant defense mode.
