Hypnotherapy is the use of hypnosis in a therapeutic context, to help clients master their own states of awareness, bodily functions, and psychological responses. Although some believe that hypnosis is a form of mind control through which a person's behavior and judgment can be controlled, this is not actually the case. A hypnotic subject is in a deep state of relaxation, and yet alert and always aware at some level.

Hypnosis has been known to work in a variety of situations, to relieve conditions with an emotional or psychological component. According to various studies, hypnosis may improve immune function, increase relaxation, decrease stress, and ease feelings of anxiety. It is for these reasons that hypnotherapy has been proven effective in reducing the fear and anxiety that accompany pain and uncomfortable medical or dental procedures. Studies indicate that using hypnosis can decrease the patient’s need for medication, improve mental and physical condition before an operation, and reduce the time it takes to recover. Hypnotherapy is also used in cases of obesity, asthma, sleep disorders such as insomnia, addictions, skin disorders such as acne and psoriasis, and migraines.

Before the first session, the hypnotherapist will ask the client a series of questions to determine the nature of problem. The specialist will explain what hypnosis is and how it works, and then direct the client through relaxation techniques with a series of mental images and suggestions to help the client change behaviors and alleviate symptoms. The hypnotherapist may also teach the client the basics of self-hypnosis to help recreate the feelings experienced during the session. Each session lasts about an hour, and most people begin to improve their condition within four to ten sessions.
