Hypervigilance: Signs, Causes and When to Get Help
Hypervigilance means constantly scanning for danger, feeling on edge and easily startled. Learn the signs, causes like PTSD and anxiety, and treatments that help you feel safe.
Hypervigilance is a state of heightened alertness in which you constantly scan for threats. Signs include being easily startled, sitting facing the door, monitoring people and noises, difficulty relaxing or sleeping, irritability and exhaustion.

You choose the seat facing the door. You notice every sound, every face, every exit. A dropped plate makes you jump out of your skin. At night you check the locks twice and still lie awake listening. If you feel like you can never fully relax, you may be experiencing hypervigilance.
This guide explains what hypervigilance is, its signs, why it happens, how it connects to trauma and anxiety, and how to help your body feel safe again. See also PTSD treatment.
What is hypervigilance?
Hypervigilance is an enhanced state of sensory sensitivity and alertness aimed at detecting danger. It is useful in genuinely dangerous situations, but when it persists in safe environments it becomes draining and disruptive. It reflects an overactive threat-detection system, especially the amygdala, and a nervous system stuck in fight-or-flight.
