Hypnosis is similar to meditation or guided imagery and can help to calm the nervous system, relieve pain, and achieve your goals. Have you ever had the experience of being so absorbed in a book or a movie, or conversation that you lost track of time, or forgot about something else? That's an example of hypnosis. It's a natural state we go in and out of all the time. Hypnotherapy is the use of hypnosis to treat behavioral health and medical conditions, such as chronic pain, anxiety, phobias, addiction, and PTSD. Studies have found that hypnosis can relieve different kinds of pain in 75% of the population.
