Research into hypnosis in military applications is further verified by the Project MKULTRA experiments, also conducted by the CIA. According to Congressional testimony, the CIA experimented with utilizing LSD and hypnosis for mind control. Many of these programs were done domestically and on participants who were not informed of the study's purposes or that they would be given drugs.
Cancer patients use relaxation and hypnosis. Evidence from randomized trials shows hypnosis and relaxation are effective for cancer-related anxiety, pain, nausea, and vomiting, particularly in children. Some practitioners also claim that relaxation techniques, particularly the use of imagery, can prolong life, although currently available evidence is insufficient to support this claim.
According to Dr. Clifford N. Lazarus, speaking for Psychology Today, hypnosis is a “genuine psychological phenomenon that has valid uses in clinical practice … hypnosis is a state of highly focused attention or concentration, often associated with relaxation, and heightened suggestibility. While under hypnosis (i.e., in a hypnotic trance), it seems many people are much more open to helpful suggestions than they usually are.” The suggestions made in a therapeutic setting get deep into a person’s brain, beyond their conscious thinking, leading to behavior change and the ability to overcome challenges that might otherwise seem insurmountable.
But psychiatrists do understand the general characteristics of hypnosis, and they have some model of how it works. It is a trance state characterized by extreme suggestibility, relaxation and heightened imagination. It's not really like sleep, because the subject is alert the whole time. It is most often compared to daydreaming, or the feeling of "losing yourself" in a book or movie. You are fully conscious, but you tune out most of the stimuli around you. You focus intently on the subject at hand, to the near exclusion of any other thought.
Sometimes those shoulds and shouldn'ts seem to only take us so far, before we reach a seemingly insurmountable hurdle that even the strongest willpower just can't quite conquer. This is because we're trying to address these issues on a purely conscious level, which is similar to applying a bandaid over an internal wound. Sooner or later, we need to deal with the root cause.
A 2006 declassified 1966 document obtained by the US Freedom of Information Act archive shows that hypnosis was investigated for military applications. The full paper explores the potentials of operational uses. The overall conclusion of the study was that there was no evidence that hypnosis could be used for military applications, and no clear evidence whether "hypnosis" is a definable phenomenon outside ordinary suggestion, motivation, and subject expectancy. According to the document:
