Interoceptive exposure is a specific technique that may be used during exposure therapy for certain anxiety disorders, especially panic disorder and PTSD. Specifically, interoceptive exposure is designed to help individuals directly confront feared bodily symptoms often associated with anxiety, such as an increased heart rate and shortness of breath. The therapist may assist this by having the client (in a controlled and safe manner) hyperventilate for a brief period of time, exercise, or hold his breath.
Interoceptive exposure was originally designed to treat panic disorder. However, there is evidence that it may be successful in the treatment of PTSD as well.
