Hypervigilance
Hypervigilance is a state of constant, increased alertness and hidden sensitivity to the surroundings, in which a person is continuously scanning the environment for potential threats or danger. This condition is based on the cognitive and behavioral defense mechanisms of the nervous system operating in a "fight or flight" mode. It is accompanied by persistent internal tension, high anxiety levels, and an accelerated response to any external stimuli (sounds, movements), often exhausting the nervous system. It serves as a key symptom of severe stress, traumatic conditions, or PTSD.
Hypervigilance continues to be a core focus of trauma studies in clinical psychology. It is surrounded by physiological changes that instill chronic exhaustion and sleep disorders. The intensity and manifestations of hypervigilance have varied depending on the duration of stress exposure. Outdated theories viewed it merely as a subjective emotional reaction, whereas modern evidence-based methods have re-established hypervigilance as a profound neurobiological response to trauma and PTSD. Currently, it is a widely recognized diagnostic criteria for trauma-related disorders, with empirical research building for many therapeutic applications.
