The word "hypnosis" (from the Greek hypnos, "sleep") is an abbreviation of James Braid's (1841) 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 can improve the success of other treatments for many conditions, including: Phobias, fears, and anxiety. Sleep disorders. Depression. Stress. Post-traumaanxiety. Grief and loss.
