Hypervigilance

« Back to Glossary Index

Hypervigilance is a state of increased alertness. If you’re in a state of hypervigilance, you’re extremely sensitive to your surroundings. It can make you feel like you’re alert to any hidden dangers, whether from other people or the environment. Often, though, these dangers are not real. Hypervigilance can be a symptom of mental health conditions, including anxiety and PTSD.
