According to William Ray, a professor of psychology and Penn State hypnosis-researcher, more than 6,000 articles on the benefits of hypnosis have been published in medical and psychological journals since the 1950s.

Documented benefits of hypnosis include:

* Can help patients allay the fear and anxiety associated with hospital life.
* Reducing or eliminating chronic pain.
* Relieving pre-operative fear, thus reducing post-surgical pain and promoting healing.
* Relief of gastrointestinal disorders such as ulcers, irritable bowel syndrome, colitis, and Crohn's disease.
* Reducing or eliminating nausea and vomiting associated with chemotherapy and pregnancy.
* Hypnosis is also effective in helping to ease fears, tension, and pain during labor and delivery.
* Asthma, allergies, and many skin disorders are often responsive to hypnotic suggestion.
