Stephen Porges explains how a locked nervous system drives chronic anxiety
Polyvagal Theory: Why You Feel So Anxious All The Time - Dr Stephen Porges - #1128
Understanding how the autonomic nervous system locks into survival mode offers a physiological roadmap to overcoming chronic anxiety, trauma, and stress-induced physical illnesses.
- 1The autonomic nervous system dictates our daily perception, behavior, and social interactions based on perceived safety.
- 2Trauma and chronic stress lock the body into defensive states, leading to physical ailments like gut issues and long COVID.
- 3Vagal nerve stimulation, humming, and co-regulation can actively signal safety to return the body to a calm state.

Dr. Stephen Porges explains how a history of trauma physically locks the nervous system into a defensive mode, making it difficult to feel safe even in secure environments.
The brief
Neuroscientist Dr. Stephen Porges explains how our underlying physiological state dictates our perception and social interactions, moving beyond the traditional fight-or-flight model to explain chronic anxiety.
When trauma or chronic stress locks the nervous system into defensive survival mode, the body remains hypervigilant, manifesting physically as poor sleep, gut issues, and even long COVID symptoms.
To pull the body out of defense, we must signal safety to the brain through melodic voices, facial expressions, and practical exercises like resonance breathing, humming, and vagal stimulation.
This physiological state also forms the biological basis of love and co-regulation, showing how cultural environments and transgenerational trauma can physically lock bodies into defense.
