Hypnotherapy is a form of talking therapy that uses hypnosis, a state of focused attention and deep relaxation, to help someone work toward a specific goal, such as reducing anxiety, easing a phobia, or breaking a habit. A trained hypnotherapist guides the person into this state and then uses suggestions or other techniques to support change. This guide covers how hypnotherapy works, what it may help with, whether research supports it, what to expect from a session, and how to find a properly qualified practitioner.
What Is Hypnotherapy?
Hypnotherapy is the therapeutic use of hypnosis. A trained practitioner guides a person into a state of focused attention and relaxation, sometimes described as a hypnotic state or trance. Within this state, the person is generally more open to suggestions related to their goal, whether that is managing anxiety, changing a habit, or reducing pain.
Hypnosis is not sleep, and it is not unconsciousness. Most people remain aware of their surroundings, can hear what is being said, and are able to speak or move if needed. Some people experience it as similar to the relaxed, drifting feeling just before falling asleep, while others describe a deeper sense of focus. Everyone experiences it a little differently, partly because of something called hypnotic susceptibility, the natural variation in how readily someone responds to hypnotic suggestion.
You may see the term subconscious used to explain how hypnotherapy works. Be cautious here: there is no scientifically settled mechanism, so it is more accurate to say hypnotherapy works through focused attention and suggestion, not a proven reprogramming of the subconscious.
How Does Hypnotherapy Work?
A typical course of hypnotherapy follows a few clear stages.
- Initial discussion. The hypnotherapist talks with you about what you want to work on and what a realistic goal looks like.
- Induction. Using relaxation techniques and verbal guidance, the therapist helps you enter a state of focused attention.
- Deepening and suggestion. Once relaxed, the therapist may offer suggestions, guided imagery, or other techniques aimed at your specific goal.
- Return to alertness. The therapist brings you gradually back to normal, full awareness.
- Follow-up. Many practitioners teach self-hypnosis techniques you can practice between sessions.
Not everyone responds to hypnosis in the same way, and hypnotic susceptibility varies from person to person. Some people find it easy to enter a focused state quickly, while others take longer or respond more mildly. Neither is a sign that hypnotherapy will or will not work for you.
Researchers are still studying exactly what happens in the brain during hypnosis. Some studies using brain imaging show changes in activity in areas linked to attention and self-awareness. Still, there is no single agreed theory that fully explains the mechanism, so claims about precise neurological effects should be treated with some caution.
What Is the Difference Between Hypnosis and Hypnotherapy?
Hypnosis is a state, a period of focused attention and increased responsiveness to suggestion. Hypnotherapy is what happens when that state is used within a therapeutic setting to work toward a specific goal, such as reducing anxiety or managing pain.
Stage hypnosis, the kind seen in entertainment shows, also uses hypnosis, but for performance rather than treatment. Performers often select volunteers who are naturally more responsive to suggestions and use the format to create an entertaining show. It is not representative of what happens in a clinical hypnotherapy session.
A few common misconceptions are worth clearing up:
- Hypnosis is not the same as being asleep.
- It is not mind control, and a hypnotherapist cannot make you do something against your will or values.
- You do not lose consciousness or all sense of control.
- You can typically stop or speak up at any point during a session.
What Is Hypnotherapy Used For?
Hypnotherapy is used for a range of goals. The most common areas include:
- Anxiety and stress. Managing anxious thoughts and physical tension. For ongoing anxiety, anxiety therapy that combines several approaches is often the more established starting point. Hypnotherapy is typically used as a complementary option alongside this, rather than on its own.
- Phobias. Often used together with gradual exposure techniques for specific phobias.
- Pain management. Used for certain types of pain, including procedural pain and some chronic pain conditions.
- Irritable bowel syndrome (IBS). Used as a psychological intervention alongside CBT and psychotherapy for people who have not responded to standard treatment.
- Smoking cessation. Widely marketed as a stop-smoking aid, though this is one of the more debated uses, covered in the next section.
Hypnotherapy is not a cure for underlying medical or psychiatric conditions. It works best as part of a wider treatment plan, not in place of one.
Does Hypnotherapy Work?
The honest answer is that it depends on what you are using it for. Evidence quality varies significantly by condition, and a single yes or no answer would be misleading.
Working through the four areas covered earlier shows just how much this varies.
IBS sits at the stronger end. NICE guidance recommends hypnotherapy be considered, alongside CBT and psychotherapy, for people with refractory symptoms who have not responded to treatment after 12 months, based on multiple studies showing benefit, though NICE has also flagged a need for larger, higher-quality trials.
Pain management is similarly well supported. Several studies and reviews back hypnotherapy as a genuinely useful tool, particularly for procedural pain.
Smoking cessation, by contrast, is where the evidence is weakest. The most recent Cochrane review of 14 studies and nearly 2,000 participants found no reliable evidence that hypnotherapy works better than other support methods or quitting unaided, despite how widely it is marketed for this purpose.
Anxiety falls somewhere in between. A reasonable body of research suggests hypnotherapy can help some people manage symptoms, but study quality varies, and it is rarely tested as a standalone treatment compared with established approaches like CBT.
Results depend heavily on the individual, their hypnotic susceptibility, the skill of the practitioner, and how the therapy is combined with other support. Claims of guaranteed or permanent results are not supported by the current evidence base.
Is Hypnotherapy Safe?
For most people, hypnotherapy carries a low risk profile when delivered by a properly trained practitioner. It does not involve medication or invasive procedures, and serious adverse effects are rarely reported in the research.
That said, it is not risk-free for everyone. Mild, temporary effects such as light-headedness, drowsiness, or emotional discomfort during a session are the most commonly reported issues.
Certain groups are generally advised to avoid or approach hypnotherapy with caution, and should speak to a doctor first. This typically includes people with active psychosis, severe dissociative symptoms, or poorly controlled epilepsy.
A responsible practitioner should ask about your health history before starting, and refer you elsewhere if hypnotherapy is not appropriate for your situation.
What Happens During a Hypnotherapy Session?
Sessions vary between practitioners, but most follow a similar general shape.
Before hypnosis
The therapist talks with you about what you want to address, asks about relevant background, and explains what the process will involve so there are no surprises.
During hypnosis
You will usually be seated or lying comfortably. The therapist guides you through relaxation and focused attention, then may use suggestions, imagery, or other techniques aimed at your specific goal. You typically remain aware throughout and can respond if needed.
After hypnosis
The therapist brings you gradually back to full alertness, and you will usually spend a few minutes discussing how the session felt and what comes next, sometimes including self-hypnosis techniques to practice at home.
What a hypnotherapist actually does, in practical terms, is combine structured conversation with relaxation and suggestion techniques tailored to your goal, rather than following one fixed script for every client.
How Many Hypnotherapy Sessions Do You Need?
There is no set number that applies to everyone. Some specific goals, like preparing for a one-off event, might be addressed in a single session. Other concerns, such as ongoing anxiety or a long-standing habit, often involve several sessions over a few weeks.
How many sessions you need depends on the issue itself, your individual response to hypnotherapy, and whether it is being used alongside other treatment. A responsible practitioner will discuss realistic expectations with you early on rather than promising a fixed number in advance.
How Do You Find a Qualified Hypnotherapist?
Hypnotherapy is not regulated by law in the UK, which means anyone can technically call themselves a hypnotherapist regardless of training. This makes it especially important to check credentials before booking.
A few practical things to look for:
- Registration with an accredited body. The Complementary and Natural Healthcare Council (CNHC) runs a voluntary UK register that has been accredited by the Professional Standards Authority, an independent body accountable to Parliament. Practitioners registered here have met defined training and conduct standards.
- Relevant experience. Ask whether the practitioner has specific experience with the issue you want help with, since not every hypnotherapist works across every area.
- Insurance. A properly practising hypnotherapist should hold professional indemnity insurance.
- Clear fees and approach. They should be able to explain their pricing and general method before you commit to a course of sessions.
- Willingness to discuss your health history. A responsible practitioner will ask about any relevant medical or mental health history and refer you elsewhere if hypnotherapy is not appropriate.
It is also worth speaking to your GP first if you have a diagnosed medical or mental health condition, particularly if you are considering hypnotherapy alongside existing treatment rather than as a replacement for it.
Frequently Asked Questions
Is hypnotherapy the same as hypnosis?
No. Hypnosis is the state of focused attention and relaxation. Hypnotherapy is the therapeutic use of that state, guided by a trained practitioner, to work toward a specific goal.
Are you conscious during hypnotherapy?
Yes, most people remain aware of their surroundings and able to hear and respond throughout a session. It is not the same as being asleep or unconscious.
Can hypnotherapy make you do something against your will?
No. Hypnotherapy cannot override your values or make you act against your own will, despite how stage hypnosis is sometimes portrayed for entertainment.
Does hypnotherapy work for everyone?
No. Responses vary from person to person, partly due to differences in hypnotic susceptibility, and results also depend on the specific issue being addressed and the quality of the available evidence for that use.
Can hypnotherapy be done online?
Yes, many practitioners offer hypnotherapy over video call, and it is generally considered a suitable format for many goals, though some people prefer in-person sessions.
Can hypnotherapy replace other treatments?
A responsible practitioner should never suggest stopping prescribed medication or an existing course of treatment because of hypnotherapy. If a hypnotherapist tells you to do this, treat it as a red flag and speak to your doctor.
What is the negative side of hypnosis?
When side effects happen, they are usually mild and pass within a few hours, most commonly a headache or a lingering groggy feeling. There is no good evidence that hypnosis itself causes lasting harm in people without the specific risk factors covered above.
