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:
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]
It may here be requisite for me to explain, that by the term Hypnotism, or Nervous Sleep, which frequently occurs in the following pages, I mean a peculiar condition of the nervous system, into which it may be thrown by artificial contrivance, and which differs, in several respects, from common sleep or the waking condition. I do not allege that this condition is induced through the transmission of a magnetic or occult influence from my body into that of my patients; nor do I profess, by my processes, to produce the higher [i.e., supernatural] phenomena of the Mesmerists. My pretensions are of a much more humble character, and are all consistent with generally admitted principles in physiological and psychological science. Hypnotism might therefore not inaptly be designated, Rational Mesmerism, in contra-distinction to the Transcendental Mesmerism of the Mesmerists.[56]
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.

Surgery/Anesthesiology (In unusual circumstances, hypnosis has been used as the sole anesthetic for surgery, including the removal of the gall bladder, amputation, cesarean section, and hysterectomy. Reasons for using hypnosis as the sole anesthetic may include: situations where chemical anesthesia is contraindicated because of allergies or hyper-sensitivities; when organic problems increase the risk of using chemoanesthesia; and in some conditions where it is ideal for the patient to be able to respond to questions or directives from the surgeon);
Hypnotherapy has been used to stop self-destructive and addictive habits like smoking. It has also been used to curb the urge to eat for overeaters, to stem the disruptive actions of tics, cure insomnia , stop bed-wetting, and minimize anxiety. Excessive stress can be generated from any number of sources and can be the springboard for anxiety. Some of the more prominent sources of anxiety and stress for which people seek hypnotherapy are: public speaking, test taking, and job stress. Hypnotherapy also works well for other anxiety disorders such as phobias and has proven to be an effective treatment for mild to moderate depression. In one study, hypnotherapy was used in conjunction with traditional cognitive therapy, to assist persons who had severe aversion to needles. The treatment was necessary, because it was essential that each participant receive periodic medical injections. However, the participants would have become non-compliant without the adjunct intervention of hypnotherapy. In another case, involving care for terminally ill cancer patients, it was concluded that hypnotherapy was more effective at enhancing quality of life and relieving anxiety and depressive symptoms, when compared to others who received traditional care.
Therefore, Braid defined hypnotism as a state of mental concentration that often leads to a form of progressive relaxation, termed "nervous sleep". Later, in his The Physiology of Fascination (1855), Braid conceded that his original terminology was misleading, and argued that the term "hypnotism" or "nervous sleep" should be reserved for the minority (10%) of subjects who exhibit amnesia, substituting the term "monoideism", meaning concentration upon a single idea, as a description for the more alert state experienced by the others.[23]

Meditation practice focuses on stilling or emptying the mind. Typically, meditators concentrate on their breath or a sound (mantra) they repeat to themselves. They may, alternatively, attempt to reach a state of “detached observation,” in which they are aware of their environment but do not become involved in thinking about it. In meditation, the body remains alert and in an upright position. In addition to formal sitting meditation, patients can be taught mindfulness meditation, which involves bringing a sense of awareness and focus to their involvement in everyday activities.
Pierre Janet originally developed the idea of dissociation of consciousness from his work with hysterical patients. He believed that hypnosis was an example of dissociation, whereby areas of an individual's behavioural control separate from ordinary awareness. Hypnosis would remove some control from the conscious mind, and the individual would respond with autonomic, reflexive behaviour. Weitzenhoffer describes hypnosis via this theory as "dissociation of awareness from the majority of sensory and even strictly neural events taking place."[38]
It is used for a wide variety of applications, and studies into its efficacy are often of poor quality[2] which makes it difficult to determine efficacy. Several recent meta-analyses and systematic reviews of the literature on various conditions have concluded that the efficacy of hypnotherapy is "not verified",[3] that there is no evidence[4][5] or insufficient evidence[6][7] for efficacy.
