What if your chronic stress, emotional triggers, anxiety, or exhaustion are not a mindset problem, but signs that your nervous system has learned protective survival patterns? In this episode of Trauma Rewired, Elisabeth Kristof and Jennifer Wallace explore the science of nervous system regulation and unpack a common phrase in trauma spaces: "trauma lives in the body."
While the body plays a central role, they discuss how trauma may be more accurately understood as patterns of brain-body communication, interpretation, prediction, and response shaped through experience. Through the lens of predictive processing and applied neuroscience, they explore how the nervous system uses past experiences to anticipate safety and threat, influencing emotions, behaviors, and physical symptoms in the present.
Together they break down the autonomic nervous system, fight and flight responses, interoception, chronic stress, and why nervous system healing is not about forcing calm or chasing a quick reset. Instead, recovery happens through small, consistent practices that help create greater flexibility, resilience, and new experiences of safety over time.
