When a person is under hypnosis, he is in a state of increased suggestibility and focused attention. With these factors at hand, a person is made to believe or feel what is needed to improve behavior. In the case of a person with low self-esteem, hypnosis helps in a way that it makes the person overcome his social and emotional insecurity by auto suggesting positive reinforcements. The person is made to focus on the idea that he can do whatever others can and that he is someone very special. Given the right focus, the person receives the idea and thought that eventually translates to better conduct and performance.
Hypnosis has many practical benefits aside from what is commonly depicted by the media. Although the founding concept of hypnosis is heightened suggestibility, it is not something as exaggerated as whats shown on tv or movies. Hypnosis can bring a lot of advantages to a persons physical, emotional and social skills through its idea of concentrating or focusing towards a certain subject (whatever is needed in the instance).
