Worry is a common phenomenon that involves a specific type of repetitive and uncontrollable thinking focused on future events or potential threats. It is characterized by a feeling of unease, nervousness, or fear about possible outcomes and is often accompanied by physical symptoms such as muscle tension, restlessness, and difficulty concentrating. Research on worry often examines the cognitive, emotional, and behavioral aspects of this phenomenon, as well as its impact on mental health and well-being. Additionally, studies may explore the factors that contribute to excessive worry, such as personality traits, cognitive biases, and environmental stressors, and the effectiveness of different interventions for managing and reducing worry.
