Hypnotherapy is widely used for the kinds of things that tend to quietly run people's lives — habit change, fears and phobias, limiting beliefs, performance anxiety (in sports, public speaking, and high-stakes professional situations), and the chronic stress that accumulates when you've been pushing too hard for too long. It's also clinically applied for anxiety, pain management, IBS, and surgical relaxation.
And yes — the evidence base has grown substantially. Across 49 meta-analyses covering 261 randomized controlled trials, hypnosis has been shown effective across all of these areas. For anxiety specifically, people receiving hypnosis showed greater reduction than the large majority of those who didn't — with even stronger results at follow-up. Meaning the changes don't just hold. They tend to deepen.
