Why boundaries matter for nervous system health

For many people with a history of chronic stress, attachment wounds, or complex trauma, boundaries don't land as neutral information — they register in the nervous system as abandonment, threat, or loss of connection. In this episode of Trauma Rewired, we explore why that happens and what it actually takes to rewire those responses at the level that matters most: the body.

This conversation reframes boundaries not as walls, ultimatums, or communication strategies, but as a nervous system skill that emerges from regulation, capacity, and internal coherence. Together with our guest, we unpack why setting boundaries from anger can feel easier than setting them from truth, why receiving boundaries can activate shame or collapse, and how post-traumatic growth allows boundaries to become a source of safety rather than disconnection.

If you've ever understood boundaries intellectually but struggled to live them relationally, this episode offers a deeper, more compassionate lens — one rooted in neuroscience, somatics, and the lived process of healing.

In this episode of Trauma Rewired, co-hosts Jennifer Wallace and Elisabeth Kristof are joined by Margy Feldhuhn, co-owner of Brain-Based Wellness, for a grounded, practical conversation about boundaries.

The conversation addresses why boundaries can feel threatening for people with relational or developmental trauma, how control dynamics get confused with protection, and what it looks like to set limits without shame, punishment, or power struggles. Whether you struggle to set boundaries, feel triggered by others' boundaries, or worry about being "too much," this episode offers language and perspective that supports safety rather than disconnection.
