Hypnosis is the induction of a deeply relaxed state, with increased suggestibility and suspension of critical faculties. Once in this state, sometimes called a hypnotic trance, clients are given therapeutic suggestions to encourage changes in behaviour or relief of symptoms. For example, in a treatment to stop smoking a hypnosis practitioner might suggest that the client will no longer find smoking pleasurable or necessary.
A child with behaviour difficulties might be more confident about managing themselves and more containment.
