But the reason why this ever works, for anyone, is still not clear. Some researchers argue that hypnosis may help us tap into “the autonomic nervous system to influence physical systems that aren’t usually under voluntary control,” Marchant writes in her book. She points to Karen Olness, a retired pediatrician and former member of the NIH Council for Complementary and Alternative Medicine, who has worked with children who could, through hypnosis, increase the temperature of their fingertips “way beyond what would be achieved merely from relaxation.”
The British Psychological Society commissioned a working group to survey the evidence and write a formal report on hypnotherapy in 2001. They found, “Enough studies have now accumulated to suggest that the inclusion of hypnotic procedures may be beneficial in the management and treatment of a wide range of conditions and problems encountered in the practice of medicine, psychiatry and psychotherapy.”

Hypnosis is not a substitute for medical treatment or psychotherapy. Bryan Bennett does not practice medicine or psychotherapy and his services are not a replacement for counseling, psychotherapy, psychiatric or medical treatment. No service or product provided is intended to diagnose or treat any disease or illness, psychological or mental health condition.
In 1784, at the request of King Louis XVI, a Board of Inquiry started to investigate whether animal magnetism existed. Among the board members were founding father of modern chemistry Antoine Lavoisier, Benjamin Franklin, and an expert in pain control, Joseph-Ignace Guillotin. They investigated the practices of a disaffected student of Mesmer, one Charles d'Eslon (1750–1786), and though they concluded that Mesmer's results were valid, their placebo-controlled experiments using d'Eslon's methods convinced them that mesmerism was most likely due to belief and imagination rather than to an invisible energy ("animal magnetism") transmitted from the body of the mesmerist.
So long as the therapist is trained and follows basic ethical norms, hypnotherapy is safe. Some people may feel dizzy or nauseous during or after being hypnotized. People who discuss traumatic memories may be subject to feelings of panic, flashbacks, or general feelings of anxiety, and the clinician or client may elect to discontinue treatment when symptoms are severe.

SWIHA offers two Hypnotherapy programs: One is a 100-hour Certificate of Excellence and the other is a Clinical Hypnotherapy Certificate. The 100-hour certificate is designed for personal enrichment, self-empowerment, or offers skills that could be added to an existing Holistic Healthcare Practitioner’s practice. The 100-hour certificate prepares graduates for membership into the American Board of Hypnotherapists (ABH) or National Association of Transpersonal Hypnotherapy (NATH).
Joe Griffin and Ivan Tyrrell (the originators of the human givens approach) define hypnosis as "any artificial way of accessing the REM state, the same brain state in which dreaming occurs" and suggest that this definition, when properly understood, resolves "many of the mysteries and controversies surrounding hypnosis".[29] They see the REM state as being vitally important for life itself, for programming in our instinctive knowledge initially (after Dement[30] and Jouvet[31]) and then for adding to this throughout life. They explain this by pointing out that, in a sense, all learning is post-hypnotic, which explains why the number of ways people can be put into a hypnotic state are so varied: anything that focuses a person's attention, inward or outward, puts them into a trance.[32]
In Test 1 Mendelsohn and colleagues found that people in the PHA group (who could experience PHA) forgot more details from the movie than people in the non-PHA group (who could not experience PHA). But in Test 2, after the suggestion was cancelled, this memory loss was reversed. People in the PHA group correctly recognized just as many details from the movie as people in the non-PHA group. Somewhat surprisingly, however, the suggestion to forget was selective in its impact. Although people in the PHA group had difficulty remembering the content of the movie following the forget suggestion, they had no difficulty remembering the context in which they saw the movie.
Hypnosis might not be appropriate for a person who has psychotic symptoms, such as hallucinations and delusions, or for someone who is using drugs or alcohol. It should be used for pain control only after a doctor has evaluated the person for any physical disorder that might require medical or surgical treatment. Hypnosis also may be a less effective form of therapy than other more traditional treatments, such as medication, for psychiatric disorders.
Hypnosis is not a psychotherapeutic treatment or a form of psychotherapy, but rather a tool or procedure that helps facilitate various types of therapies and medical or psychological treatments. Only trained health care providers certified in clinical hypnosis can decide, with their patient, if hypnosis should be used along with other treatments. As with psychotherapy, the length of hypnosis treatment varies, depending on the complexity of the problem.
