What is hypnotherapy and what it isn’t
There are few therapeutic modalities more misunderstood than hypnotherapy. The popular image draws from stage performances, old films, mind-control thrillers, and a few centuries of theatrical history. The clinical reality is something different. It’s considerably less dramatic, better supported by research than most people realise, and worth understanding on its own terms before deciding whether it’s for you.
This is an attempt to lay it out plainly: what hypnotherapy actually is, what it isn’t, what the evidence supports, and where it might fit in the broader landscape of mental health and wellbeing care in Australia. I’m a practising clinical hypnotherapist; this is my perspective on the field, informed by clinical work and the research literature. As with anything else worth understanding, it pays to do your own reading and form your own view.
Disclosure: I’m a practising clinical hypnotherapist based in Sydney, a member of the Hypnotherapy Council of Australia, and a founding member of the International Strategic Psychotherapists Association. I run a separate clinical practice; this article isn’t promoting it. See editorial standards for the full picture.
What hypnotherapy actually is
The clearest contemporary definition comes from the American Psychological Association’s Division 30 (Society of Psychological Hypnosis), which in 2014 published the field’s most widely used working definitions:
Hypnosis: A state of consciousness involving focused attention and reduced peripheral awareness characterised by an enhanced capacity for response to suggestion. Hypnotherapy: The use of hypnosis in the treatment of a medical or psychological disorder or concern.
These definitions are deliberately spare. They don’t claim hypnosis is mystical, magical, or unusual. They describe a state of focused attention with reduced peripheral awareness, framed neutrally so that the working definition is compatible with multiple theoretical understandings of how hypnosis actually works.
The everyday version of this state is more familiar than people realise. Becoming completely absorbed in a book, losing track of time during a long drive on a familiar route, getting “in the zone” during exercise or creative work, slipping into reverie while listening to music. All involve a similar narrowing of attention and reduced awareness of surroundings. Clinical hypnosis induces a comparable state more deliberately and uses it as the context for therapeutic work.
Throughout that state, the client remains aware. They can hear what’s being said. They can open their eyes, speak up, end the session, or simply ignore a suggestion that doesn’t sit right. The process is collaborative; the hypnotherapist is a guide, not an operator.
A brief history of why this is confusing
The popular perception of hypnosis is at least a century behind the clinical reality, and there are reasons for that.
The modern story of hypnosis begins in the late 1700s with Franz Anton Mesmer, a Viennese physician who claimed to manipulate a universal “animal magnetism” flowing between living beings. His salons in Paris were theatrical, his patients often dramatic, and his framework was eventually rejected by the scientific establishment of the day, including by a French royal commission that included Benjamin Franklin. The word “mesmerism” survived. The theory did not.
What did survive was the observation that something real was happening to Mesmer’s patients, even if his explanation for it was wrong. The Scottish surgeon James Braid, who observed mesmeric demonstrations in the 1840s, recognised the phenomenon as psychological rather than mystical. He coined the term “hypnosis” from the Greek word for sleep, a choice he later regretted because the state isn’t sleep. The name stuck anyway.
Over the 19th and early 20th centuries, hypnosis moved through several reputational phases. The French neurologist Jean-Martin Charcot used it in his studies of hysteria. Sigmund Freud experimented with it before moving toward psychoanalysis. Stage hypnotists toured for entertainment and built the cultural image that still shapes public perception today. By the early 20th century, the clinical use of hypnosis had become marginal and the theatrical version dominant.
The modern era of clinical hypnotherapy began in the 1930s, when the American psychologist Clark Hull and his student Milton Erickson began rigorous experimental and clinical work. Erickson went on to develop therapeutic approaches that still underpin much of contemporary practice. The American Psychological Association and American Medical Association formally recognised hypnotherapy as a valid clinical procedure in 1958. The US National Institutes of Health endorsed its use for chronic pain in 1995. More recent neuroimaging studies, including work from Stanford’s David Spiegel and colleagues, have mapped what changes in the brain during hypnosis. Particularly, reductions in activity in the brain’s default mode network (the part responsible for self-referential thought and mind wandering) and shifts in connectivity between regions involved in attention and body awareness.
So the science has been quietly building for nearly a century. The public perception has been catching up much more slowly. Most people considering hypnotherapy today are working from a mental image shaped by entertainment, not by the clinical literature, and that’s the gap this article exists to close.
What hypnotherapy isn’t
Most of what people imagine when they think about hypnotherapy is closer to fiction than fact. The misconceptions persist partly because they’re entertaining and partly because the visible examples of hypnosis (stage shows, films) are designed to dramatise rather than explain. Here’s what hypnotherapy isn’t.
It isn’t stage hypnosis. Stage hypnosis is entertainment. The performer pre-selects highly suggestible audience members (a small fraction of any crowd), and the social context (the lights, the audience, the implicit permission to play along) does much of the work. The behaviour you see isn’t representative of clinical hypnosis any more than a cooking competition is representative of nutrition science.
It isn’t mind control. This is the single most common misconception, and it isn’t accurate. Hypnotherapy cannot compel a person to act against their values, beliefs, or wishes. The state of focused attention doesn’t override agency. A client who finds themselves uncomfortable with the direction of a session can open their eyes, speak up, or end the session entirely. Research from the American Psychological Association and others has shown consistently that hypnosis is collaborative, not coercive.
It isn’t sleep. Despite the name (which Braid himself regretted), hypnosis isn’t a sleep state. EEG studies show hypnosis produces brainwave patterns distinct from any stage of sleep. Clients are alert, aware, and processing what’s said to them, often more attentively than in ordinary conversation.
It isn’t memory recovery. A school of hypnotherapy popular in the 1980s and 1990s used hypnosis to “recover” supposedly repressed memories, particularly of childhood trauma. Subsequent research found that hypnosis substantially increases the risk of false memories. The recall feels vivid and certain even when the content is constructed. The contemporary clinical consensus, including from the American Psychological Association, is that hypnosis is not an appropriate tool for memory recovery. Reputable contemporary practitioners do not work this way.
It isn’t supernatural or spiritual. It isn’t channelling, energy healing in any clinical sense, or contact with guides and ancestors. Practitioners who frame hypnotherapy as a mystical practice are doing something different from clinical hypnotherapy, even when they share the word.
It isn’t only for the highly suggestible. A worry I hear from clients before they start: “what if hypnosis just doesn’t work on me?” Decades of research using standardised scales (the Stanford and Harvard hypnotic susceptibility scales) have suggested that around 10 to 15 percent of adults are highly responsive, around 10 to 15 percent are minimally responsive, and most people sit somewhere in between. Those scales exist for academic research; they aren’t typically used in clinical practice. My own view, drawn from working with clients, is that what gets called “susceptibility” looks much more like willingness once you’re actually doing the work. The people who get the most from hypnotherapy aren’t the ones with some special hypnotic gift. They’re the ones who arrive wanting to change something specific and ready to engage with the process.
Here’s a small demonstration of what I mean. Imagine biting into a lemon. Picture cutting it open. The smell, the wet pulp, the moment your teeth break the skin. Notice what happens. Most people find their mouth starts to water and a faint sour sensation appears, all from imagined input alone. That’s called an ideosensory response, and it’s a small version of the same mind-body link clinical hypnotherapy works with at greater depth. If imagining a lemon produced any noticeable physical effect, you’ve already shown more capacity than the susceptibility framing typically suggests.
It isn’t a substitute for medical or psychiatric care. Hypnotherapy may have a useful supporting role in many conditions, but it isn’t a primary intervention for acute mental illness, severe depression, suicidality, untreated psychosis, or significant medical conditions. The right starting point for these is a GP, psychiatrist, or psychologist, with hypnotherapy potentially in a supporting role if and when appropriate.
What actually happens in a session
A typical clinical hypnotherapy session in Australia runs around 60 to 90 minutes. The structure varies between practitioners and modalities, but a common pattern looks something like this.
The first part of the session is conversation. The hypnotherapist asks about the issue you’re bringing, what you’ve already tried, what outcome you’re hoping for, and any context that matters. Some sessions are entirely conversational on the first visit, with the hypnotic work beginning at the second.
When the hypnotic part of the session begins, the hypnotherapist will typically guide you through some form of induction. This is a process designed to settle attention and bring you into the focused state. Common inductions involve guided relaxation, attention to breathing, attention to a specific image or sensation, or simply directed conversation. Different modalities use different inductions, and some are more direct than others.
Once you’re in the state, the actual therapeutic work happens. The exact content depends on what you’re working on and the practitioner’s approach. It might involve suggestions for change, working with imagery, exploring patterns, or rehearsing different responses to a situation that’s been giving you trouble. The hypnotic portion of a session is often around 20 to 30 minutes within the broader session length.
At the end, the hypnotherapist guides you out of the hypnotic state and discusses what came up. Many practitioners provide a recording of the trance portion of the session for you to listen to between appointments. The next session usually picks up where the last left off and builds on the work.
The whole thing is more ordinary than the popular image suggests. There are no swinging pocket watches, no count-downs to dramatic unconsciousness, no sudden “you are getting sleepy” performances. A skilled practitioner makes the work feel like a conversation that occasionally moves into a deeper, quieter register, and then comes back out.
What the evidence supports
The evidence base for clinical hypnotherapy is stronger than its reputation suggests, particularly in specific applications. A short, honest summary of where the research currently stands:
Well-supported applications:
- Gut-directed hypnotherapy for irritable bowel syndrome (IBS). Multiple meta-analyses and randomised controlled trials show meaningful effects, often comparable to dietary interventions like the low-FODMAP diet. Australian research, particularly at Monash University, has contributed substantially to this evidence base.
- Chronic pain management. Hypnotherapy has been recognised by the US National Institutes of Health since 1995 as an effective adjunct for chronic pain. Subsequent meta-analyses have continued to support this finding.
- Procedural pain and anxiety. Hypnotic techniques are used in some hospitals around the world as adjuncts during medical procedures, with measurable reductions in reported pain and anxiety.
Moderately supported applications:
- Smoking cessation. The evidence is mixed but generally supportive. Hypnotherapy appears to be effective for some people, often comparable to or better than nicotine replacement therapy alone, though long-term outcomes are harder to demonstrate reliably.
- Anxiety symptoms. A 2019 meta-analysis published in the International Journal of Clinical and Experimental Hypnosis found hypnotherapy was associated with meaningful reductions in anxiety symptoms across multiple studies, with effects often maintained at follow-up.
- Insomnia and sleep difficulties. A small but growing body of research suggests hypnotic suggestion can deepen slow-wave sleep and reduce the time it takes to fall asleep.
Areas where claims should be treated cautiously:
- Weight loss as a standalone outcome. Hypnotherapy may support behaviour change around eating, but claims of substantial sustained weight loss from hypnotherapy alone are not strongly supported.
- “Cure” claims for any serious medical condition. Reputable practitioners do not make these claims.
The general principle worth carrying with you: the strength of evidence varies considerably across applications. Hypnotherapy is well-evidenced for some things and exploratory for others. A practitioner who treats it as universally effective for everything is overclaiming.
Different approaches within hypnotherapy
Hypnotherapy isn’t one single thing. Practitioners trained in different schools and traditions use distinct approaches, even when working on similar issues. Worth knowing the broad landscape, without me favouring any particular school.
Ericksonian hypnotherapy draws on the work of Milton Erickson. It tends to use indirect suggestion, metaphor, and storytelling rather than direct command. The approach is conversational and flexible, often tailored closely to each individual client.
Traditional or “classical” hypnotherapy uses more direct suggestion, formal inductions, and structured scripts. It’s the closest of the major approaches to the popular image, and it’s still used effectively in some contexts.
Strategic hypnotherapy and brief therapy approaches focus on identifying and interrupting specific patterns rather than processing content at length. Sessions are typically brief and outcome-focused.
Cognitive behavioural hypnotherapy combines hypnotic technique with cognitive behavioural therapy. The approach has growing evidence support, particularly for anxiety and mood-related issues.
NLP-influenced hypnotherapy draws on Neuro-Linguistic Programming alongside hypnotic technique. Some practitioners integrate this; others don’t. The evidence base for NLP itself is separately contested, which is worth being aware of.
A practitioner may draw on one approach predominantly, or combine several. None of these is the “right” form of hypnotherapy. They suit different practitioners and different clients, and the differences are part of why finding the right fit matters.
When hypnotherapy might be worth considering
Hypnotherapy tends to be most useful for issues that are pattern-based and discrete: anxiety responses, specific fears and phobias, ingrained habits, sleep difficulties, certain pain conditions, IBS, and similar. The evidence base is strongest in these areas, and the brief, focused nature of most clinical hypnotherapy fits the work well.
It tends to be less useful for diffuse, open-ended problems, complex trauma processing requiring longer-term work, primary psychiatric conditions, and situations where the issue is fundamentally medical rather than psychological.
For most people, the right question isn’t “is hypnotherapy a good idea generally?” The better question is “is hypnotherapy a good fit for what I’m trying to work on?” That’s a conversation worth having with a practitioner who’s honest about both what hypnotherapy can do and what it can’t.
