The short version
- •Clinical hypnosis (hypnotherapy) uses a guided state of focused attention and heightened suggestibility to help change perceptions, sensations, or responses — it is not mind control or stage hypnosis, and you stay aware and in control.
- •Its strongest evidence is for pain (including chronic and procedural pain) and irritable bowel syndrome, where meta-analyses support meaningful benefit.
- •For depression and anxiety the evidence is more modest, and it is generally adjunctive — a helpful add-on to first-line treatments rather than a standalone treatment.
- •It is typically brief and is often combined with CBT ("cognitive hypnotherapy").
- •Effectiveness varies with individual hypnotic suggestibility, which differs from person to person.
- •Hypnotherapy is the most cautiously framed option here: real and evidence-based for specific indications, but not a substitute for established treatments of moderate-to-severe depression, anxiety, or PTSD.
What it is
Clinical hypnosis is the therapeutic use of hypnosis — a state of focused attention, absorption, and heightened responsiveness to suggestion, guided by a trained clinician. It bears no resemblance to stage hypnosis or popular myth: people under clinical hypnosis remain aware, retain control, cannot be made to act against their values, and can end the state at will. In treatment, the focused state is used to deliver therapeutic suggestions — for example, altering the experience of pain, calming physiological arousal, or reinforcing coping and new perspectives — and it is frequently integrated with cognitive-behavioral techniques ("cognitive hypnotherapy"). Responsiveness varies: hypnotic suggestibility is a measurable trait that differs across individuals and predicts how much benefit hypnosis adds. The honest evidence picture is uneven by indication — robust for some physical conditions, more modest and adjunctive for mood and anxiety — so hypnotherapy is best understood as a useful tool for specific purposes and as an adjunct, rather than a primary treatment for serious mental illness.
What it helps with
Among hypnosis's strongest indications — meta-analyses support meaningful pain reduction, especially in more suggestible individuals.
Anxiety
Can help as an adjunct, particularly for procedural and situational anxiety; more modest evidence as a standalone.
Some evidence exists, but it is more limited; used adjunctively, not as a primary treatment for moderate-to-severe depression.
Relaxation-focused hypnosis can support sleep as an adjunct.
What to expect
Induction and focused state
The clinician guides you into a relaxed, absorbed, focused state — you stay aware and in control throughout.
Therapeutic suggestion
Targeted suggestions address the specific goal (pain, calm, coping), often combined with CBT skills.
Brief and skill-building
Often a short course, with self-hypnosis taught for ongoing use.
Variable response
Benefit depends partly on individual hypnotic suggestibility.
The evidence
The evidence for hypnosis is genuinely indication-dependent. For pain, a systematic review and meta-analysis (Thompson 2019) found hypnosis produces clinically meaningful pain relief, especially in those with higher suggestibility, and it has strong evidence in IBS as well. For depression, a meta-analysis (Milling 2019) found hypnotic interventions had a positive effect, though this literature is smaller and hypnosis is generally used adjunctively rather than as a standalone treatment for moderate-to-severe depression. The honest summary: well-supported for specific physical and adjunctive uses, more modest for primary psychiatric treatment.
How it pairs with ketamine
Hypnotherapy is the most adjunctive of the therapies here, and its relationship to ketamine is correspondingly modest. Where it may add value is in the shared territory of focused attention and absorption: relaxation and self-hypnosis skills can help some patients prepare for and settle into the ketamine experience, and hypnotic techniques are sometimes used to support pain and anxiety that co-occur with the conditions Tovani treats. But for moderate-to-severe or treatment-resistant depression, anxiety, or PTSD, the established treatments — including ketamine and the better-evidenced psychotherapies — remain primary, with hypnosis a possible complement rather than a substitute.
Frequently asked
Is hypnosis real / does it actually work?
Clinical hypnosis is real and evidence-based for specific uses — particularly pain and IBS, where meta-analyses show meaningful benefit. It is not stage hypnosis or mind control: you stay aware and in control. For depression and anxiety the evidence is more modest, and it is generally used as an add-on rather than a standalone treatment.
Can I be hypnotized against my will?
No. Clinical hypnosis is a collaborative, guided state of focused attention; you remain aware, retain control, can't be made to act against your values, and can end it at any time. Responsiveness also varies — hypnotic suggestibility differs from person to person.
What is hypnosis best for?
Its strongest evidence is for pain (chronic and procedural) and irritable bowel syndrome. It can help anxiety adjunctively and has some evidence in depression, but for moderate-to-severe mental illness it is a complement to first-line treatments, not a replacement.
Does hypnosis fit with ketamine therapy?
Modestly. Relaxation and self-hypnosis skills may help some people prepare for and settle into the ketamine experience, and hypnosis can support co-occurring pain or anxiety. But for the depression, anxiety, or PTSD Tovani treats, ketamine and the better-evidenced therapies remain primary, with hypnosis a possible add-on.
