Prolonged exposure is a therapeutic technique primarily used to treat anxiety disorders, especially post-traumatic stress disorder (PTSD) and obsessive-compulsive disorder (OCD). This method involves repeatedly exposing individuals to the thoughts, feelings, and situations associated with their anxiety in a controlled and safe environment. The goal is to help individuals confront their fears, reduce avoidance behaviors, and ultimately desensitize them to the anxiety-provoking stimuli over time.
