“Hypnosis, also referred to as hypnotherapy or hypnotic suggestion, is a trance-like state in which you have heightened focus, concentration and inner absorption. When you’re under hypnosis, you usually feel calm and relaxed, and you can concentrate intensely on a specific thought, memory, feeling or sensation while blocking out distractions. “
“Under hypnosis, you’re more open than usual to suggestions, and this can be used to modify your perceptions, behavior, sensations and emotions. Therapeutic hypnosis is used to improve your health and well-being and is different from so-called stage hypnosis used by entertainers. Although you’re more open to suggestion during therapeutic hypnosis, your free will remains intact and you don’t lose control over your behavior. “
“Hypnosis is intended to help you gain more control over undesired behaviors or emotions or to help you cope better with a wide range of medical conditions. Hypnosis isn’t considered a treatment or a type of psychotherapy. Rather, it’s a procedure typically used along with certain treatments and therapies to help a wide variety of conditions.”
“Hypnosis may help you cope better with certain medical conditions, stop unwanted habits or reduce stress related to medical procedures. The effects of hypnosis can be long lasting and can improve your overall quality of life.”
