Self-hypnosis happens when a person hypnotizes oneself, commonly involving the use of autosuggestion. The technique is often used to increase motivation for a diet, quit smoking, insomnia or to reduce stress. People who practice self-hypnosis sometimes require assistance; some people use devices known as mind machines to assist in the process, whereas others use hypnotic recordings.

Self-hypnosis is claimed to help with stage fright, relaxation, and physical well-being.
