Hypnosis, also referred to as hypnotherapy or hypnotic suggestion, is a trance-like state in which you have heightened focus and concentration. Hypnosis is usually done with the help of a therapist using verbal repetition and mental images.
Hypnosis has been used in the treatment of pain; depression; anxiety and phobias; stress; habit disorders; gastro-intestinal disorders; skin conditions; post-surgical recovery; relief from nausea and vomiting; childbirth; treatment of hemophilia and many other conditions.
“In hypnosis, we know you can alter things like gastric acid secretion, heart rate, blood pressure and skin conductance,” Spiegel said. “Your brain is very good at controlling what’s going on in your body, and the insula is one of the pathways that does that.”
Extreme cases of repeated hypnosis can even eventually derange the brain, as when ordinary people start behaving in grotesque ways and think of others not as humans but as ‘things’.
