Hypnotherapy may help treat any number of medical conditions in which psychological factors influence physical symptoms. Common mental health uses include: Stress and anxiety, especially before medical or dental procedures; panic attacks; and post-traumatic stress syndrome (PTSD).

Relaxation techniques — including hypnosis — can sometimes ease anxiety. Hypnosis tends to be more effective in people whose anxiety stems from a chronic health condition — such as heart disease — rather than from a generalized anxiety disorder.
