Anxiety is a natural human response to stress or perceived danger, often characterized by feelings of worry, nervousness, or unease. It can manifest in various ways, including physical symptoms such as increased heart rate, sweating, trembling, or dizziness. Anxiety can be a normal reaction to certain situations, such as facing a big test or a job interview, but when it becomes excessive or chronic, it may interfere with daily life and well-being. People with anxiety disorders may experience persistent and intense anxiety that is out of proportion to the actual threat or situation. Common types of anxiety disorders include generalized anxiety disorder, panic disorder, social anxiety disorder, and specific phobias. Treatment options for anxiety may include therapy, medication, lifestyle changes, and stress management techniques. It is important to seek help if anxiety significantly impacts one's quality of life.
