Understanding the Impact of the Nervous System on Stress Responses

What if your constant stress, emotional triggers, and exhaustion aren’t a mindset problem, but a sign your nervous system is stuck in survival mode? 

In this episode of Trauma Rewired, we explore the science of nervous system reset, nervous system regulation, and how to restore the nervous system after chronic stress and trauma. Jennifer Wallace and Elisabeth Kristof unpack how the autonomic nervous system governs your reactions, why trauma is stored as patterns in the body, and how to begin the process of nervous system recovery without forcing or overwhelming yourself.

You’ll learn how the sympathetic (fight or flight) and parasympathetic (rest and digest) branches work together, why dysregulation is not a personal failure, and how practices like movement, breathwork, and interoception can help you regulate more effectively. This conversation also covers the difference between “big T” and “small T” trauma, why nervous system healing requires both individual and collective approaches, and how to build resilience so you can meet life’s challenges without staying stuck in survival mode.

This episode is both a science-backed education and a compassionate guide for anyone ready to experience a genuine nervous system reset.
