Self-hypnosis works because we are able to condition ourselves to various stimuli. We condition ourselves consciously and unconsciously to many activities. When we experience anxiety, it stems from a conditioning process which could have been conscious or unconscious. In self-hypnosis, the individual consciously works toward implementing and strengthening his own inherent strength and resources. These objectives, when attained, result in feelings of confidence, relaxation, self-mastery and well-being. Furthermore, hypnosis utilizes a natural mental process. We all know that placebos work admirably in numerous cases. The dictionary defines the word placebo as, "an inactive substance or preparation, administered to please or gratify a patient, also used in controlled studies to determine the efficiency of medicinal substances." Many controlled experiments have shown that people achieve similar results whether they take a placebo (which they think is the real medication) or real medication that was prescribed. Several years ago many such tests were carried out with antihistamines to prevent colds. The results were always the same. We are interested in what makes the placebo act as effectively as the true medication. It stands to reason that a chain reaction is set up, actually causing a physiological result from a psychological reaction. The unsuspecting patient declares, "I've never felt so good in my life." Yet, this would never have happened if he didn't think he was taking the marvelous new medicine. A recent scientific study by one of the leading pharmaceutical houses concluded that one third of the effectiveness of any medication depends upon the faith and trust that the patient has in the prescribing physician. I am sure that the placebo results and the patient's faith in the physician as contributing factors to the effectiveness of medications do not come as a revelation. We are all aware of such information. Our problem is how to harness this unconscious process for constructive goals. The answer is through self-hypnosis.
