Systematic desensitization is a psychological technique used to help individuals overcome phobias and anxiety disorders. It involves gradually exposing a person to the feared object or situation in a controlled manner while teaching relaxation techniques. This process helps reduce the fear response over time. The method typically consists of three main steps: creating a fear hierarchy, practicing relaxation techniques, and gradually exposing the individual to the feared stimuli, starting with the least anxiety-provoking scenario. By repeatedly facing their fears in a safe environment, individuals can learn to manage their anxiety and reduce their fear responses effectively.
