What the Research Says About Self-Hypnosis

These are the studies we cite across Mind Refuge, grouped by topic, with what each one found and its limits. We list only studies we have read on PubMed, and we say so when the research is thin.

Keep in mind that these studies looked at hypnosis in general, not at Mind Refuge. Mind Refuge is a wellness and self-improvement tool: it doesn’t diagnose or treat any condition, and it doesn’t replace a doctor or therapist.

Stress and anxiety

The strongest evidence is for anxiety, where hypnosis works best alongside other psychological care. For everyday stress, the evidence is promising but smaller.

Valentine et al. (2019). The efficacy of hypnosis as a treatment for anxiety: a meta-analysis. Int J Clin Exp Hypn.
Pooled 17 controlled trials. People who received hypnosis reduced anxiety more than control groups, and hypnosis worked best when combined with other psychological treatment.
Fisch, Brinkhaus & Teut (2017). Hypnosis in patients with perceived stress: a systematic review. BMC Complement Altern Med.
Six of nine small randomized trials found less perceived stress with hypnosis, but all had a high risk of bias. The authors concluded the effect on stress was still unclear.
Fisch et al. (2020). Group hypnosis for stress reduction and improved stress coping: a multicenter randomized controlled trial. BMC Complement Med Ther.
95 stressed but healthy adults. Five weekly group sessions plus hypnosis recordings for home practice lowered perceived stress more than an educational booklet alone, at 5 and 12 weeks.

Before a stressful moment

Much of the research looks at hypnosis before or during medical procedures. These are clinical settings, but they show how a calm, guided state can help ahead of a stressful moment, including with recordings.

Holler et al. (2021). Efficacy of hypnosis in adults undergoing surgical procedures: a meta-analytic update. Clin Psychol Rev.
50 randomized trials, 4,269 patients. Hypnosis reduced mental distress and pain around surgery, though results varied widely between studies.
Walter et al. (2025). Hypnosis as a non-pharmacological intervention for invasive medical procedures: a systematic review and meta-analytic update. J Psychosom Res.
20 randomized trials, 1,250 patients. Hypnosis reduced anxiety and pain during invasive medical procedures compared with standard care, with minimal side effects.
Lahoud, Gurary & Elia (2026). Hypnosis for anaesthetists: a systematic review and meta-analyses. Anaesthesia.
142 studies, more than 9,000 patients. Hypnosis before a procedure was linked to less anxiety and pain afterwards, but its effect on most other outcomes remains unknown.
Montgomery et al. (2002). The effectiveness of adjunctive hypnosis with surgical patients: a meta-analysis. Anesth Analg.
20 controlled studies of surgical patients. Patients who received hypnosis had better outcomes, with no significant difference between live and recorded hypnosis.
Napp et al. (2021). Audio-guided self-hypnosis for reduction of claustrophobia during MR imaging. Eur Radiol.
An observational study, not a randomized trial. Patients who listened to an audio self-hypnosis recording before an MRI had fewer claustrophobic events (16% vs 43%) than a comparison group.
Pachaiappan, Tee & Low (2023). Effect of self-hypnosis on test anxiety among secondary school students in Malaysia. Int J Clin Exp Hypn.
22 students, with no control group. Test anxiety scores went down over five weeks of self-hypnosis practice. A small, early study.

Focus and attention

Research on hypnosis and attention is early and comes from the lab. It shows that suggestion can change performance on an attention task in highly suggestible people. We found no study showing that self-hypnosis improves everyday focus or concentration.

Raz et al. (2006). Suggestion reduces the Stroop effect. Psychol Sci.
A lab study with highly suggestible adults. A suggestion to see words as meaningless symbols reduced Stroop interference, a classic test of attention control, with or without a formal hypnotic induction.
Raz et al. (2007). Suggestion overrides the Stroop effect in highly hypnotizable individuals. Conscious Cogn.
A follow-up lab study: in highly hypnotizable people, a posthypnotic suggestion reduced, and in some cases removed, Stroop interference.
Augustinova & Ferrand (2012). Suggestion does not de-automatize word reading: evidence from the semantically based Stroop task. Psychon Bull Rev.
Replicated the reduced Stroop interference, but found that people still processed word meaning. Suggestion seems to change how competing responses are handled, not switch reading off.

Procrastination

We found no studies on hypnosis for procrastination. Research on procrastination itself helps explain why starting is hard, and what tends to help.

Steel (2007). The nature of procrastination: a meta-analytic and theoretical review of quintessential self-regulatory failure. Psychol Bull.
Not a hypnosis study. The strongest predictors of procrastination were how unpleasant a task feels, how far off its reward is, low self-efficacy and impulsiveness.
Rozental et al. (2018). Targeting procrastination using psychological treatments: a systematic review and meta-analysis. Front Psychol.
Not a hypnosis study. Psychological treatments had a small effect on procrastination overall; cognitive behavioural therapy did better, in only three studies.

Sleep

Research on hypnosis for sleep is promising but limited.

Chamine, Atchley & Oken (2018). Hypnosis intervention effects on sleep outcomes: a systematic review. J Clin Sleep Med.
24 studies. 58% reported a sleep benefit from hypnosis, but samples were small and study quality was modest.

Hypnosis and meditation

Hypnosis and meditation overlap but are not the same practice. Few studies compare them directly, and the ones that do show mixed results.

Penazzi & De Pisapia (2022). Direct comparisons between hypnosis and meditation: a mini-review. Front Psychol.
Few experiments compare hypnosis and meditation directly. Some point to distinct states, others to shared features, and there is no consensus yet.
Sim et al. (2024). Neural correlates of mindfulness meditation and hypnosis on magnetic resonance imaging: similarities and differences. A scoping review. J Neuroradiol.
Brain imaging studies show some shared patterns between meditation and hypnosis, and some differences. The authors call for more rigorous studies.
Jensen et al. (2025). Hypnosis and mindfulness audio recordings for reducing fatigue in individuals with multiple sclerosis: a randomized controlled study. Mult Scler.
333 people with multiple sclerosis. Access to either hypnosis or mindfulness audio recordings reduced fatigue more than usual care, with similar results for both.
Reme et al. (2026). Preoperative hypnosis versus mindfulness for reducing postoperative symptoms in breast surgery: a randomized clinical trial. Anesthesiology.
203 women before breast cancer surgery. A brief hypnosis session led to less fatigue and emotional distress afterwards than a mindfulness session, but not less pain or nausea.

Hypnosis apps

Hypnosis apps vary widely in quality, and few say who provides the hypnosis. Every Mind Refuge session is voiced by a certified hypnotherapist; Mind Refuge itself has not been tested in a clinical trial.

Scheffrahn et al. (2025). Hypnosis apps: a systematic review. Int J Clin Exp Hypn.
168 hypnosis apps reviewed. Only 20% said the person providing the hypnosis was trained in hypnosis, and only four had been part of a clinical trial.
