Hypnotherapy is therapy that is undertaken with a subject in hypnosis.
The word “hypnosis” (from the Greek hypnos, “sleep”) is an abbreviation of James Braid’s (1843) term “neuro-hypnotism”, meaning “sleep of the nervous system”.
A person who is hypnotized displays certain unusual characteristics and propensities, compared with a non-hypnotized subject, most notably hyper-suggestibility, which some authorities have considered a sine qua non of hypnosis. Hypnotherapy is often applied in order to modify a subject’s behavior, emotional content, and attitudes, as well as a wide range of conditions including dysfunctional habits, anxiety, stress-related illness, pain management, and personal development.
Many people routinely experience a trance-like state while they are watching television or sitting at a red light. A person in a trance or deeply focused state is unusually responsive to an idea or image, but this does not mean that a hypnotist can control the person’s mind and free will. On the contrary, hypnosis can actually teach people how to master their own states of awareness. By doing so they can affect their own bodily functions and psychological responses.
