Research
The evidence behind the work.
Hypnotherapy is often mistaken for a stage act. In clinical settings it is a well-studied tool. Below are peer-reviewed studies, systematic reviews, and meta-analyses on hypnosis for fertility, stress, performance, chronic pain, and pain in childbirth — with a plain-language note on what each one found.
Fertility and IVF
Fertility treatment is physically and emotionally demanding. These trials look at what happens to stress hormones, coping, and outcomes when hypnosis is added to standard care.

Stress and anxiety
Most of what I treat starts with a nervous system stuck in high alert. Hypnosis has one of the more consistent evidence bases for turning that volume down.
Hypnosis and the Treatment of Anxiety: A Meta-Analysis
Valentine KE, Milling LS, Clark LJ, Moriarty CL
International Journal of Clinical and Experimental Hypnosis, 2019

Read the study →Brain Activity and Functional Connectivity Associated with Hypnosis
Jiang H, White MP, Greicius MD, Waelde LC, Spiegel D
Cerebral Cortex, 2017 (Stanford)
Brain imaging during hypnosis showed measurable changes in the regions that govern attention, self-awareness, and body control — evidence that the hypnotic state is a real, distinct brain state.

Performance and habit change
The same focused state that quiets fear can also sharpen confidence, focus, and follow-through — in sport, in work, and in changing a habit.

Barnes J, et al.
Cochrane Database of Systematic Reviews
Cochrane reports hypnotherapy performs comparably to other behavioral counselling for quitting; evidence is promising but not yet conclusive — an honest look at where the science stands.

Chronic and acute pain
Pain is processed in the brain, which is exactly where hypnosis works. This is the strongest evidence base of all the areas on this page.
The effectiveness of hypnosis for pain relief: A systematic review and meta-analysis of 85 controlled experimental trials
Thompson T, Terhune DB, Oram C, et al.
Neuroscience & Biobehavioral Reviews, 2019
Across 85 controlled trials, hypnotic analgesia produced clinically meaningful pain reduction — with the largest effects in people with medium-to-high suggestibility.

Systematic review, 2025
Journal of Clinical Medicine, 2025

Pain and coping in childbirth
Hypnosis for birth is not about a pain-free promise. The research points to less need for pharmacological pain relief and a calmer, more self-directed experience.
Hypnosis for pain management during labour and childbirth (Cochrane Review)
Madden K, Middleton P, Cyna AM, Matthewson M, Jones L
Cochrane Database of Systematic Reviews, 2016
Women using hypnosis were less likely to use pharmacological pain relief or epidural analgesia, though the review calls for larger, higher-quality trials.

An honest note
Research describes averages, not promises. Hypnosis works differently for different people, and it is a complement to medical care — never a replacement for it. As a registered nurse, I will always encourage you to keep your care team in the loop.
