Overview

Anxiety is a psychological and physiological state characterized by feelings of worry, fear, nervousness, or apprehension, often accompanied by bodily symptoms such as increased heart rate, muscle tension, and restlessness. As a normal emotion, anxiety serves an adaptive function, alerting people to potential threats and preparing them to respond, but when it becomes excessive, persistent, or disproportionate to actual circumstances, it can interfere with daily functioning and constitute an anxiety disorder. Anxiety involves the interplay of cognitive processes, emotional responses, and neurobiological systems, including stress-response pathways and neurotransmitter signaling, and it is influenced by genetic, developmental, environmental, and social factors. It frequently co-occurs with depression and other conditions, and it can be assessed and treated through psychological therapies, behavioral approaches, and, where appropriate, medication. Within the scope of Human Psychology, this collection includes directly relevant work, including a review of the role of cholecystokinin in fear and anxiety, a study of the effectiveness of treating anxiety with Reiki, research on anxiety and depression among nursing students, and a randomized trial of somatosensory stimulation for reducing stress-related cortisol and anxiety. The page gathers peer-reviewed, open-access research relevant to anxiety, its mechanisms, its measurement, and its treatment.
