Seven faces of hyperarousal: a new map of stress responses
A study of 467 adults by the Netherlands Institute for Neuroscience identifies seven distinct dimensions of hyperarousal—anxious, somatic, sensitive, sleep-related, irritable, vigilant, and sudomotor—each with different symptoms. The findings suggest hyperarousal is multi-dimensional and linked to conditions like insomnia and ADHD, with potential implications for diagnosis and treatment.
