Hypnotherapy is a use of hypnosis in psychotherapy.[84][85][86] It is used by licensed physicians, psychologists, and others. Physicians and psychologists may use hypnosis to treat depression, anxiety, eating disorders, sleep disorders, compulsive gambling, and posttraumatic stress,[87][88][89] while certified hypnotherapists who are not physicians or psychologists often treat smoking and weight management.
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.
Hypnosis is first and foremost a self-accepted journey away from the reality of the moment. Although the trance state is often referred to as if the patient is asleep, nothing could be further from the truth. The patient is fully awake at all times. The hypnotic subject is simply in a heightened, more receptive state of mind. This fact is proven with inductions called open-eye techniques, where the patient keeps his/her eyes open during the hypnotherapy. Full and deep trance is still achievable.

Take any bright object (e.g. a lancet case) between the thumb and fore and middle fingers of the left hand; hold it from about eight to fifteen inches from the eyes, at such position above the forehead as may be necessary to produce the greatest possible strain upon the eyes and eyelids, and enable the patient to maintain a steady fixed stare at the object.
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.
