A wide variety of the complementary therapies claim to improve health by producing relaxation. Some use the relaxed state to promote psychological change. Others incorporate movement, stretches, and breathing exercises. Relaxation and “stress management” are found to a certain extent within standard medical practice. They are included here because they are generally not well taught in conventional medical curricula and because of the overlap with other, more clearly complementary, therapies.​therapies.
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.

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.
But how does the suppression mechanism decide what to suppress? In this study, movie content but not movie context was influenced by PHA. Memories involve the “what,” “how,” “when” and “where” of an event interwoven together, such that distinctions between content and context may be blurred (for example, “Was the movie shot with a hand-held camera?”). To make such fine discriminations, the brain’s suppressor module presumably needs to process information at a sufficiently high level. Yet this module needs to act quickly, preconsciously suppressing activation of the information before it even enters awareness. Brain imaging technologies with superior temporal resolution to fMRI, such as magnetoencephalography (MEG), might help to resolve this seeming paradox of sophisticated, yet rapid, operations.
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.
The American Society of Clinical Hypnosis (ASCH) is unique among organizations for professionals using hypnosis because members must be licensed healthcare workers with graduate degrees. As an interdisciplinary organization, ASCH not only provides a classroom to teach professionals how to use hypnosis as a tool in their practice, it provides professionals with a community of experts from different disciplines. The ASCH's missions statement is to provide and encourage education programs to further, in every ethical way, the knowledge, understanding, and application of hypnosis in health care; to encourage research and scientific publication in the field of hypnosis; to promote the further recognition and acceptance of hypnosis as an important tool in clinical health care and focus for scientific research; to cooperate with other professional societies that share mutual goals, ethics and interests; and to provide a professional community for those clinicians and researchers who use hypnosis in their work. The ASCH also publishes the American Journal of Clinical Hypnosis
Changes in brain activity have been found in some studies of highly responsive hypnotic subjects. These changes vary depending upon the type of suggestions being given.[168][169] The state of light to medium hypnosis, where the body undergoes physical and mental relaxation, is associated with a pattern mostly of alpha waves[170] However, what these results indicate is unclear. They may indicate that suggestions genuinely produce changes in perception or experience that are not simply a result of imagination. However, in normal circumstances without hypnosis, the brain regions associated with motion detection are activated both when motion is seen and when motion is imagined, without any changes in the subjects' perception or experience.[171] This may therefore indicate that highly suggestible hypnotic subjects are simply activating to a greater extent the areas of the brain used in imagination, without real perceptual changes. It is, however, premature to claim that hypnosis and meditation are mediated by similar brain systems and neural mechanisms.[172]
It appears that hypnosis, under other names, has been used since the beginning of time. In fact, it has been insinuated that the earliest description of hypnosis may be portrayed in the Old Testament and in the Talmud. There is also evidence of hypnosis in ancient Egypt, some 3,000 years ago. However, the man credited with the development of what has become modern hypnosis is Friedrich Anton Mesmer, an Austrian physician. One day, Mesmer watched a magician on a street in Paris demonstrate that he could have spectators do his bidding by touching them with magnets. Fascinated by the demonstration, Mesmer believed the magnets had power of their own and from this belief developed his theory of "animal magnetism." He also believed that good health depended on having correct magnetic flow and that the direction of one's magnetic flow could be reversed easily. He further believed that he could direct this magnetic flow into inanimate objects, that could then be used for the good health of others. The term "mesmerism" came to be applied to his mystical workings. He experienced much success in helping the people of Paris as well as visitors who came from other countries, upon hearing of his powers. Later he was completely discredited by a special commission of the French Academy appointed by the King of France, causing him to leave the country. Two of the more famous members of the French Academy at the time were chairman of the commission Benjamin Franklin, American ambassador to France, and Dr. Guillotine, the inventor of the execution device.
The therapy is commonly used as an aid to psychotherapy due to the relaxed nature brought on by the hypnotic state that allows people to explore painful and suppressed feelings and emotions or memories that are often hidden from their conscious minds. This change in consciousness can often lead patients to experience things differently outside of hypnosis, such as criticism at work or home, stage fright, or even pain.
Many religions do not condone the practice of hypnotherapy. Leaders of the Jehovah's Witnesses and Christian Science religions oppose the use of hypnotherapy and advise their members to avoid it completely, whether for entertainment or therapy. The Church of Jesus Christ of Latter-Day Saints approves it for medical purposes, but cautions members against allowing themselves to be hypnotized for entertainment or demonstration purposes.

During hypnosis, a person is said to have heightened focus and concentration. The person can concentrate intensely on a specific thought or memory, while blocking out sources of distraction.[7] Hypnotised subjects are said to show an increased response to suggestions.[8] Hypnosis is usually induced by a procedure known as a hypnotic induction involving a series of preliminary instructions and suggestion. The use of hypnotism for therapeutic purposes is referred to as "hypnotherapy", while its use as a form of entertainment for an audience is known as "stage hypnosis". Stage hypnosis is often performed by mentalists practicing the art form of mentalism.

Hypnotherapy is used in a number of fields including psychotherapy, surgery, dentistry, research, and medicine. Hypnotherapy is commonly used as an alternative treatment for a wide range of health conditions, including weight control, pain management, and smoking cessation. It is also used to control pain in a variety of conditions such as headache, facial neuralgia, arthritis, burns, musculoskeletal disorders, childbirth, and many more. Hypnotherapy is being used in place of anesthesia, particularly in patients who prove to be allergic to anesthetic drugs, for surgeries such as hysterectomies, cesarean sections, certain cardiovascular procedures, thyroidectomy, and others. Dentistry is using hypnotherapy with success on patients who are allergic to all types of novocaine drugs. Hypnotherapy is also useful in helping patients overcome phobias.
Azam's enthusiasm for hypnotism influenced Ambroise-Auguste Liébeault, a country doctor. Hippolyte Bernheim discovered Liébeault's enormously popular group hypnotherapy clinic and subsequently became an influential hypnotist. The study of hypnotism subsequently revolved around the fierce debate between Bernheim and Jean-Martin Charcot, the two most influential figures in late 19th-century hypnotism.
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]
This state of awareness can be achieved by relaxing the body, focusing on breathing, and shifting attention away from the external environment. In this state, the patient has a heightened receptivity to suggestion. The usual procedure for inducing a hypnotic trance in another person is by direct command repeated in a soothing, monotonous tone of voice.
A hypnotherapist is a skilled and trained professional who, by inducing a trance-like state, helps people use their subconscious mind to change behavioural patterns or ways of thinking. It is important that the client is really wanting to change their negative thoughts, feelings or behaviours in order for the hypnotherapist be able to help the client.

Major Landmark Achievement for Hypnotherapy: The Hypnotherapy Academy of America is now exclusively providing the National Institutes of Health (NIH) with the hypnotherapy methods to use in their research of mind-body medicine. After a highly successful clinical trial at UNMH, in which our (copyright protected) “Integral Hypnotherapy™” methodology was utilized, it was concluded that our methods are “superior” when compared to another style of therapy. This led to the new, three-year NIH study of hypnotherapy in which its design parameters make the research the most trusted by physicians and behavioral health professionals.  Click here for details Scientific Research on Hypnosis
To investigate the effectiveness of cognitive hypnotherapy (CH), hypnosis combined with cognitive-behavioral therapy (CBT), on depression, 84 depressives were randomly assigned to 16 weeks of treatment of either CH or CBT alone. At the end of treatment, patients from both groups significantly improved compared to baseline scores. However, the CH group produced significantly larger changes in Beck Depression Inventory, Beck Anxiety Inventory, and Beck Hopelessness Scale. Effect size calculations showed that the CH group produced 6%, 5%, and 8% greater reduction in depression, anxiety, and hopelessness, respectively, over and above the CBT group. The effect size was maintained at 6-month and 12-month follow-ups. This study represents the first controlled comparison of hypnotherapy with a well-established psychotherapy for depression, meeting the APA criteria for a "probably efficacious" treatment for depression.
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.

Braid can be taken to imply, in later writings, that hypnosis is largely a state of heightened suggestibility induced by expectation and focused attention. In particular, Hippolyte Bernheim became known as the leading proponent of the "suggestion theory" of hypnosis, at one point going so far as to declare that there is no hypnotic state, only heightened suggestibility. There is a general consensus that heightened suggestibility is an essential characteristic of hypnosis. In 1933, Clark L. Hull wrote:
The weird thing is I was a really shy kid, and would never act like a moron or do embarrassing stuff (like he has us do) in front of my whole school - WILLINGLY! But I DID! I remember feeling really calm, and confident and WANTED to put on a fun show for the school. It felt like the audience was cloudy and obscured by a fog and I just felt so calm and zen like in a trance - but totally aware and intentionally playing along. The last thing he has us do at the end of the event was ask for a signature from anyone we met, believing they were a celebrity (we were instructed to have them sign our hands). I remember people's expressions, they thought we were insane, but i felt empowered by being able to convince others that I was hypnotized - like they were being laughed at not me.
     "When I started I was taking it for a thesis topic and only expected to complete the first level. The more I learned, the more I realized this is what I really wanted to do. By the time of my Level 4 Graduation, I felt this could be my profession. I quickly developed a full-time hypnotherapy practice, with at least 6-8 clients per day. I have referrals referring referrals!
