Over the last few decades hypnosis has become increasingly recognized as a valuable therapeutic tool, not just by the public but also by the medical profession. As a consequence, research funds have been made available to run clinical tests to investi-gate the workings of hypnosis. Most research still comes from the US, but tests under laboratory conditions have also been carried out in Canada, Australia, Germany and other European countries.
Research has focused on a variety of physical functions which are measured before, during and after hypnosis. It has been found that, while a subject is in hypnosis, the breathing rate and heart beat slow down, the bronchi of the lungs dilate, blood-pressure drops and the production of stomach acid is reduced. In addition, no stress hormones are released into the bloodstream. Scientists at the University of Constance have observed that, even in subjects in only a light trance, white blood cells cling more firmly to blood vessels, which is thought to increase the body’s immune efficiency. The body also seems to produce more of these immune-enhancing lymphocytes while under hypnosis, which could explain why hypnosis has been used successfully in the treatment of cancerous cells.
These scientific findings make it clear why hypnosis (used either as self-hypnosis or induced by a therapist) is an ideal tool to help alleviate physical problems such as asthma, tension headaches, stomach disorders, high blood-pressure and many other stress-related problems.
