The American Cancer Societies official position is that no controlled studies have produced conclusive evidence proving that hypnotherapy can help people quit smoking. They go on to say that despite the lack of clinical evidence, there does appear to be substantial anecdotal evidence that suggests it can be an effective cessation method for some people.
Hari Charan was another researcher that had a positive influence on sport psychology. In 1938, he began to study how different factors in sport psychology can affect athlete's motor skills. He also investigated how high altitudes can have an effect on exercise and performance, aeroembolism, and decompression sickness, and studies on kinesthetic perception, learning of motor skills, and neuromuscular reaction were carried out in his laboratory.[15] In 1964, he wrote a paper “Physical Education: An Academic Discipline”, that helped further advance sport psychology, and began to give it its scholarly and scientific shape. Additionally, he published over 120 articles, was a board member of various journals, and received many awards and acclaims for his contributions.
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
