Hypnosis is effective in decreasing the fear of cancer treatment[127] reducing pain from[128] and coping with cancer[129] and other chronic conditions.[116] Nausea and other symptoms related to incurable diseases may also be managed with hypnosis.[130][131][132][133] Some practitioners have claimed hypnosis might help boost the immune system of people with cancer. However, according to the American Cancer Society, "available scientific evidence does not support the idea that hypnosis can influence the development or progression of cancer."[134]
Self-hypnosis happens when a person hypnotises oneself, commonly involving the use of autosuggestion. The technique is often used to increase motivation for a diet, to quit smoking, or to reduce stress. People who practise self-hypnosis sometimes require assistance; some people use devices known as mind machines to assist in the process, whereas others use hypnotic recordings.
As we celebrate 50 years in the field and 40 years as a leading school, hypnotherapy is transforming many aspects of the health professions and is truly revolutionizing the counseling professions. We are honored to have a major role in this, leading the way with powerful, innovative therapy methods and by using the insights and therapy methods of ourselves and others to train thousands of graduates from 50 countries, including many leaders in the field.
Hypnosis is normally preceded by a "hypnotic induction" technique. Traditionally, this was interpreted as a method of putting the subject into a "hypnotic trance"; however, subsequent "nonstate" theorists have viewed it differently, seeing it as a means of heightening client expectation, defining their role, focusing attention, etc. There are several different induction techniques. One of the most influential methods was Braid's "eye-fixation" technique, also known as "Braidism". Many variations of the eye-fixation approach exist, including the induction used in the Stanford Hypnotic Susceptibility Scale (SHSS), the most widely used research tool in the field of hypnotism.[33] Braid's original description of his induction is as follows:
Hypnotherapy is used for nonmedical patients as well as those who wish to overcome bad habits. Hypnotherapy has been shown to help those who suffer from performance anxiety, such as in sports, and speaking in public. In academic applications, it has also been shown to help with learning, participating in the classroom, concentrating, studying, focusing attention span, improving memory, and helping remove mental blocks about particular subjects.

Neuro-Linguistic Programming (NLP) is the name given to a series of models and techniques used to enhance the therapist's ability to do hypnotherapy. NLP consists of a number of models, with a series of techniques based on those models. Sensory acuity and physiology is one model whose premise is that a person's thought processes change their physiological state. People recognize such a physiological change when startled. The body receives a great dose of adrenaline, the heart beats faster, the scare may be verbalized by shouting, and the startled person may sweat. Sensory acuity, (i.e., being attuned to changes occurring in another person) will strengthen communication to a person in ways over and above simple verbal cues, therefore making the therapist more effective. A second model of NLP deals with representational systems. The idea behind this model is that different people represent knowledge in different sensory styles. In other words, an individual's language reveals that person's mode of representation. There are three basic modes of representation. These are: Auditory, Visual, and Kinesthetic. The same information will be expressed differently by each. For example, the auditory person might say, "That sounds good to me;" the visual person might convey, "I see it the same way;" and the kinesthetic person would offer, "I'm comfortable with it too."
The earliest definition of hypnosis was given by Braid[contradictory], who coined the term "hypnotism" as an abbreviation for "neuro-hypnotism", or nervous sleep, which he contrasted with normal sleep, and defined as: "a peculiar condition of the nervous system, induced by a fixed and abstracted attention of the mental and visual eye, on one object, not of an exciting nature."[21]
So far, so good. For people in the PHA group, brain activation measured by fMRI correlated with the failure to remember. But what if reduced activation is always found in such people regardless of whether they are remembering or forgetting? We can rule this possibility out because people in the PHA group showed reduced activation only when they (unsuccessfully) answered questions about the content of the movie, not when they (successfully) answered questions about the context of the movie. Indeed, for the context questions, they showed the same activation as people in the non-PHA group. Perhaps then, the reduced activation reflects complete forgetting of the information, not just temporary suppression? We can rule this possibility out also because, in a neat reversal, people in the PHA group showed normal activation—just as those in the non-PHA group did—as soon as the suggestion was cancelled.
In 2013, the then-40-year-old amateur hypnotist Timothy Porter attempted to sexually abuse his female weight-loss client. She reported awaking from a trance and finding him behind her with his pants down, telling her to touch herself. He was subsequently called to court and included on the sex offender list.[161] In 2015, Gary Naraido, then 52, was sentenced to 10 years in prison for several hypnosis-related sexual abuse charges. Besides the primary charge by a 22-year-old woman who he sexually abused in a hotel under the guise of a free therapy session, he also admitted to having sexually assaulted a 14-year-old girl.[162]
Adverse events resulting from relaxation techniques are uncommon. Rare reports describe basilar or vertebral artery occlusion after yoga postures that put particular strain on the neck. People with poorly controlled cardiovascular disease should avoid progressive muscle relaxation because abdominal tensing can cause the Valsalva response. Patients with a history of psychosis or epilepsy have reportedly had further acute episodes after deep and prolonged meditation.
Hypnosis is a powerful tool to help clients overcome challenging issues such as anxiety, phobias, pain management, hot flashes and more. Hypnosis is also a way to help let go of addictions like smoking, overeating and gambling. In and of itself, hypnosis is not a therapy, but it can be used in conjunction with therapy to empower and encourage the person receiving it to make positive change. Some people are more susceptible to hypnosis and will benefit more from hypnotherapy than others.
Abnormal results can occur in instances where amateurs, who know the fundamentals of hypnosis, entice friends to become their experimental subjects. Their lack of full understanding can lead to immediate consequences, which can linger for some time after the event. If, for example, the amateur plants the suggestion that the subject is being bitten by mosquitoes, the subject would naturally scratch where the bites were perceived. When awakened from the trance, if the amateur forgets to remove the suggestion, the subject will continue the behavior. Left unchecked, the behavior could land the subject in a physician's office in an attempt to stop the itching and scratching cycle. If the physician is astute enough to question the genesis of the behavior and hypnosis is used to remove the suggestion, the subject may experience long-term negative emotional distress and anger upon understanding exactly what happened. The lack of full understanding, complete training, and supervised experience on the part of the amateur places the subject at risk.
Around 1900, there were very few preoperative anesthetic drugs available. Patients were naturally apprehensive when facing surgery. One out of four hundred patients would die, not from the surgical procedure, but from the anesthesia. Dr. Henry Munro was one of the first physicians to use hypnotherapy to alleviate patient fears about having surgery. He would get his patients into a hypnotic state and discuss their fears with them, telling them they would feel a lot better following surgery. Ether was the most common anesthetic at that time, and Dr. Munro found that he was able to perform surgery using only about 10% of the usual amount of ether.

Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
