In recent years, hypnosis has become an accepted medical therapy to address a variety of conditions, including childbirth pain and weight loss, which are concerns for many women. This increased popularity is probably due to research that shows hypnosis can produce profound improvements in health—though we know very little about the mechanisms by which these improvements are made. The word hypnosis comes from ancient Greek and means “a mental state like sleep” -but as a therapy, it isn’t so easily defined. Though hypnosis produces changes in the body, it appears as if these physiological changes occur through our own mental processes.
