Stress and Hypervigilance: When the Threat System Won't Turn Off

How hypervigilance drives Stress and evidence-based approaches for calming the overactive threat system.

Hypervigilance — a state of elevated threat detection that persists even in safe environments — is both a symptom and driver of stress.

What Hypervigilance Looks Like in Stress

  • Constantly scanning the environment for threats related to stress
  • Interpreting ambiguous information as threatening
  • Difficulty relaxing even when safe
  • Exaggerated startle response
  • Exhaustion from sustained threat monitoring

The Neurological Basis of Hypervigilance in Stress

Hypervigilance in stress reflects an amygdala that has been conditioned to fire easily. This is adaptive in genuinely dangerous environments but becomes a stress driver in safe ones.

Reducing Hypervigilance in Stress

  • Safety signaling: Deliberately noticing evidence of safety in the environment
  • Exposure: Gradual, safe exposure to stress triggers reduces amygdala reactivity over time
  • Somatic practices: Body-based calming directly addresses the physiological component of hypervigilance
  • Trauma therapy: When hypervigilance has trauma origins, trauma-focused therapy addresses roots
