One treatment procedure used to accomplish this goal is "interoceptive exposure," or the deliberate evocation of anxiety-related body sensations via exercises such as hyperventilation, spinning in a swivel chair, or running in place. By demonstrating that the experience of anxiety-related body sensations does not lead to physical catastrophes, interoceptive exposure exercises help individuals learn not to fear their own anxiety symptoms. Indeed, this procedure is considered an essential ingredient in evidence-based psychological treatment of panic disorder.
