Hypnosis for anxiety: what the research shows

Which kind of anxiety are we talking about?

Researchers separate two things that everyday language calls “anxiety”. State anxiety is how anxious you feel right now, for example in the hour before surgery or an exam. Trait anxiety and anxiety disorders are longer-lasting patterns: worry most days for months, repeated panic attacks, or avoidance that shapes your life.

The distinction matters because the evidence for hypnosis is not the same for both. A 2010 review concluded that hypnosis is efficacious for state anxiety before tests, surgery and medical procedures. The same review said more randomized trials are needed for GAD and for changes in trait anxiety.^[2] The newer research since then fits that picture.

What the 2019 meta-analysis found

The most cited summary is Valentine and colleagues’ 2019 meta-analysis. They screened 399 records and kept 15 studies containing 17 trials in which hypnosis was compared with a control condition.^[1]

• At the end of treatment, the mean weighted effect size was 0.79. The authors translate this as the average person who received hypnosis reducing anxiety more than about 79% of people in control groups.^[1]
• Seven trials had follow-up data. At the longest follow-up the effect size was 0.99, or better than about 84% of control participants.^[1]
• Hypnosis worked better when it was combined with other psychological interventions than when it was used on its own.^[1]

Two cautions. Seventeen trials is a small evidence base, and only seven measured whether the benefit lasted. The abstract also reports one pooled number across all the trials, so it cannot tell you how hypnosis performs for one specific diagnosis.

Anxiety before surgery, procedures and the dentist

This is where the evidence is largest. A 2025 meta-analysis of 20 randomized trials with 1,250 patients found that hypnosis reduced anxiety during invasive medical procedures compared with standard care (standardized mean difference −0.43). It also reduced pain, heart rate and blood pressure, with minimal adverse effects.^[4]

A 2026 review for anaesthetists pooled 142 studies with 9,238 patients. Hypnosis before or during a procedure reduced anxiety, but the authors stressed that its effect on most other outcomes is still unknown.^[3]

Dental research shows the same split between short-term and long-term anxiety. A 2024 review of 173 dental trials found moderate-certainty evidence that hypnosis reduces state anxiety during oral surgery. For long-standing dental anxiety and dental phobia, the supported treatment was CBT.^[5] If this is your situation, see our guide to hypnosis for medical procedure anxiety.

Test anxiety

Exam anxiety is a common target in hypnosis studies, but many of them are small. One of the better designed is a 2022 randomized trial in 90 medical students with high test anxiety. They received six weekly 30-minute sessions of either hypnosis or progressive muscle relaxation, with equal total time.^[6]

Both groups improved. About 64% of the hypnosis group and 62% of the relaxation group showed clinically significant improvement, but test anxiety scores were lower after hypnosis, both at the end and at a two-month follow-up.^[6] So on clinically significant improvement, a matched relaxation program did almost as well. That is a useful reminder that part of what hypnosis offers is structured relaxation practice.

What about GAD and panic disorder?

Here the trial base is thin. We did not find a meta-analysis of hypnosis limited to people diagnosed with GAD or panic disorder, and the 2010 review called for more randomized trials in GAD.^[2]

The first-line options are well established. The US National Institute of Mental Health describes CBT as the “gold standard” psychotherapy for GAD, and lists SSRI and SNRI antidepressants among the effective medicines.^[9] The UK’s NICE guideline offers CBT or applied relaxation as the high-intensity psychological options, or an SSRI such as sertraline, and says to base the choice on the person’s preference.^[10]

Panic attacks raise their own problems, such as why breathing advice often fails in the moment. We cover that in why “just breathe” fails during a panic attack.

Where hypnosis fits: an add-on to CBT

The idea of hypnosis as an add-on goes back to a 1995 meta-analysis by Kirsch, Montgomery and Sapirstein. Across 18 studies, the average client who got CBT plus hypnosis improved more than at least 70% of clients who got the same CBT without it.^[7]

That study needs two caveats. First, it covered several conditions, and the abstract singles out obesity, not anxiety, as the area with the largest effect.^[7] Second, a 1996 re-analysis of its weight-loss studies corrected transcription and calculation errors and found a much smaller effect.^[8] The more recent anxiety-specific data point in the same direction: hypnosis worked better alongside other psychological interventions than alone.^[1]

In practice, that means hypnosis can sit next to CBT. It gives you a relaxed, focused state in which to rehearse the skills therapy teaches. It does not replace the therapy.

What this means if you want to try it

• For a known stressful event, such as a procedure, an exam or a flight, the evidence for hypnosis is reasonable. Practice before the day, not only on it.
• For anxiety that has lasted months, start with an assessment and a first-line treatment. Use hypnosis alongside it if you find it helps.
• Expect a relaxation benefit even if you are not very responsive to hypnosis. The test anxiety trial suggests relaxation alone does a lot of the work.^[6]
