Which of the following is a defining feature of anxiety disorders?

The defining feature of anxiety disorders is characterized by tension that arises from perceived or imagined threats. Individuals with anxiety disorders often experience excessive worry or fear that is out of proportion to the actual danger present. This can manifest through constant apprehension about various aspects of life, leading to physical symptoms such as increased heart rate, muscle tension, and restlessness. Unlike other issues like low self-esteem or compulsive eating, which may be associated with different mental health conditions, the core of anxiety disorders is the heightened sense of danger and the emotional and physical tension that comes with it. Thus, the essence of anxiety disorders lies in the intense and persistent reactions individuals have towards threats they foresee, whether those threats are real or not.
