Facial Signals

Playing Section
  • 1

    Faces broadcast internal physiological states more than words.

  • 2

    Nervous systems evolved to detect safety cues through facial and vocal expressions.

  • 3

    Effective listening requires embodied presence, not just hearing words.

Polyvagal Theory, developed by Stephen Porges, explains that the autonomic nervous system operates through three distinct states—calmness (social engagement), mobilization (fight/flight), and shutdown (immobilization)—which fundamentally shape how we perceive and respond to the world; trauma occurs when the body becomes chronically retuned to a threat state, disrupting normal physiological regulation and manifesting as various physical and psychological symptoms, but healing is possible through practices that restore vagal tone and promote social co-regulation.
