Hypnotherapy is known to be effective in helping people with several unsavory issues. Namely, hypnosis has been used to help with sleeping issues, and is known to be effective treatment for insomnia, restlessness, gaining more restorative sleep and even sleepwalking. Hypnosis has also been used as an additional aid for other afflictions such as anxiety, addictions, and chronic pain. While not as common, hypnotism has been used to uncover traumatic memories, which, in some instances, can be beneficial for healing mental health conditions.
