Hypnotherapy is a form of psychotherapy used to create change in a patient while in a state of sleep, or unconsciousness, known as hypnosis. The word hypnosis comes from the Greek word “hypnos” which simply means, “sleep.” The therapy itself uses guided relaxation techniques from a trained hypnotist that invoke feelings of intense relaxation, concentration, and/or focus to achieve a heightened state of awareness or trance-like state.

“That study changed the whole landscape,” said Dave Patterson, a psychologist at the University of Washington in Seattle, who has been using hypnosis since the 1980s to help burn victims withstand the intense pain that comes with the necessary but excruciating bandage removal and wound cleaning. Since the ’90s, other well-designed, controlled studies have been published showing similar changes in brain activity. In another slightly trippy example, researchers suggested to people in a hypnotic state that the vibrant primary colors found in paintings by Piet Mondrian were actually shades of gray. “Brain-scan results of these participants showed altered activity in fusiform regions involved in color processing,” notes psychologist Christian Jarrett.

Several professional organizations and licensing agencies exist for hypnotherapy practitioners. Examples include the American Society of Clinical Hypnosis (ASCH) and the American Association of Professional Hypnotherapists. To be an ASCH member, practitioners must attend at least 40 hours of workshop training, 20 hours of individual training, and have completed at least two years of clinical practice as a hypnotherapist.
Hypnotherapy employs the use of hypnosis—an altered state of consciousness caused by little more than the power of suggestion—to help facilitate behavioral and emotional change. A trained hypnotherapist can cause a trancelike state in clients by using auditory, visual, or other perceptual cues. Once the person enters the hypnotic state, he or she is much more suggestible, making it easier to discuss memories, gain insight, and alter behavior.
For some psychologists who uphold the altered state theory of hypnosis, pain relief in response to hypnosis is said to be the result of the brain's dual-processing functionality. This effect is obtained either through the process of selective attention or dissociation, in which both theories involve the presence of activity in pain receptive regions of the brain, and a difference in the processing of the stimuli by the hypnotised subject.[137]
The American Psychological Association published a study comparing the effects of hypnosis, ordinary suggestion, and placebo in reducing pain. The study found that highly suggestible individuals experienced a greater reduction in pain from hypnosis compared with placebo, whereas less suggestible subjects experienced no pain reduction from hypnosis when compared with placebo. Ordinary non-hypnotic suggestion also caused reduction in pain compared to placebo, but was able to reduce pain in a wider range of subjects (both high and low suggestible) than hypnosis. The results showed that it is primarily the subject's responsiveness to suggestion, whether within the context of hypnosis or not, that is the main determinant of causing reduction in pain.[138]
Hypnosis, an enhanced state of inner focus, can be an effective tool for improving a range of symptoms, including those related to mood and learning. The ADHD drug methylphenidate (Concerta, Ritalin) has been shown to increase hypnotizability in a sample of patients with ADHD and thus may enable patients to benefit from adding hypnosis to their treatment regimens.

State theorists interpret the effects of hypnotism as due primarily to a specific, abnormal, and uniform psychological or physiological state of some description, often referred to as "hypnotic trance" or an "altered state of consciousness". Nonstate theorists rejected the idea of hypnotic trance and interpret the effects of hypnotism as due to a combination of multiple task-specific factors derived from normal cognitive, behavioural, and social psychology, such as social role-perception and favorable motivation (Sarbin), active imagination and positive cognitive set (Barber), response expectancy (Kirsch), and the active use of task-specific subjective strategies (Spanos). The personality psychologist Robert White is often cited as providing one of the first nonstate definitions of hypnosis in a 1941 article:

Pioneers in this field, such as James Braid and James Esdaile discovered that hypnosis could be used to successfully anesthetize patients for surgeries. James Braid accidentally discovered that one of his patients began to enter a hypnotic state while staring at a fixed light as he waited for his eye examination to begin. Since mesmerism had fallen out of favor, Braid coined the term hypnotism, which is derived from the Greek word for sleep. Braid also used the techniques of monotony, rhythm, and imitation to assist in inducing a hypnotic state. As of 2000, these techniques are still in use.

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]

Bryan is very insightful and caring individual. Back in August I was struggling with my direction in life, not knowing what and where to go next, I was feeling confused and stressed. I decided to drive to TX and meet with Bryan. After one hypnosis session with hm I felt so good and my mind was cleared, as it turns out all the answers were already inside of me, i just needed someone to help me access them. From then I knew what I was suppose to be doing in life. Today I have a wonderful practice in my profession. He took me from the place of fear and confusion to a place of clarity and confidence. Thumbs up! Erick S, Lexington KY
Mesmer developed a general theory of disease he called “animal magnetism,” which held that every living thing carries within it an internal magnetic force, in liquid form. Illness arises when this fluid becomes blocked, and can be cured if it can be coaxed to flow again, or so Mesmer’s thinking went. To get that fluid flowing, as science journalist Jo Marchant describes in her recent book, Cure, Mesmer “simply waved his hands to direct it through his patients’ bodies” — the origin of those melodramatic hand motions that stage hypnotists use today.”
Cognitive behavioural hypnotherapy (CBH) is an integrated psychological therapy employing clinical hypnosis and cognitive behavioural therapy (CBT).[14] The use of CBT in conjunction with hypnotherapy may result in greater treatment effectiveness. A meta-analysis of eight different researches revealed "a 70% greater improvement" for patients undergoing an integrated treatment to those using CBT only.[15]
