Exposure Therapy refers to a form of behavioral therapy that slowly exposes a person to whatever triggers their problem; a form of therapy in which clients are exposed to stimuli or situations for which they have great fear. Moreover, it is defined as a behavioral technique for reducing anxiety in which patients expose themselves in real life or in fantasy to stimuli or situations that are feared or avoided. The exposure must provoke anxiety, must be of sufficient duration, and must be repeated until all anxiety is eliminated, to be effective.
