For many, it’s a clock-swinging magician or a comedy act that forces an unwitting volunteer to make embarrassing public admissions on stage. But hypnosis has a surprisingly robust scientific framework. Clinical research has shown that it can help relieve [pain](https://www.tandfonline.com/doi/abs/10.1080/00207144.2021.1920330?journalCode=nhyp20) and [anxiety](https://www.tandfonline.com/doi/abs/10.1080/07357907.2021.1998520?journalCode=icnv20) and aid [smoking cessation](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6568235/), [weight loss](https://psycnet.apa.org/record/2018-03961-001), and [sleep](https://pubmed.ncbi.nlm.nih.gov/26365453/). It can help children and adolescents better regulate their feelings and behaviors. Some people can even use “[self-hypnosis](https://psycnet.apa.org/record/2018-53495-001)” to manage stress, cope with life’s challenges, and improve their physical and emotional health. Hypnosis creates “a non-judgmental immersive experience,” says Dr. David Spiegel, a Stanford University psychiatrist and leading researcher of hypnosis. It’s been used in various forms for centuries, but it wasn’t until 1843 that the Scottish surgeon Dr. James Braid [popularized](https://www.britannica.com/biography/James-Braid-British-surgeon) the term “hypnosis.” Braid’s central discovery—that concentration can guide the brain toward a more suggestible state—was and remains controversial. But physicians have continued to test and teach the technique over the centuries with great success, Spiegel says. --- ### More from TIME --- Today, a psychologist, psychiatrist, or other healthcare professional certified in hypnotherapy will first screen a potential client for their ability to be hypnotized using a validated [suggestibility scale](https://hypnosisandsuggestion.org/suggestibility-scales.html). (Not everyone is equally susceptible to hypnosis, but research has found that about [two-thirds of adults](https://www.sciencedirect.com/topics/medicine-and-dentistry/hypnotic-susceptibility) are.) The hypnotherapist will talk with them about what sort of sensory experiences make them feel safe, like a lakeshore retreat or a beach vacation. Then, the hypnotherapist will conjure that imagery—focusing, for example, on the salt spray of the ocean, seagulls calling overhead, and sun-kissed skin—to help the person go deeper into the calming visualization. If done right, the patient’s physical surroundings will melt away. The result is a [powerful combination](https://psycnet.apa.org/record/1991-98107-004) of dissociation, immersion, and openness to new experiences, which culminates in what was once called a “trance,” but which modern hypnotherapists simply refer to as a “hypnotic state.” It can be achieved in just a few minutes, Spiegel says. Such scene-setting techniques can create the ideal stage for positive transformation, says Binghamton University psychology professor Steven Jay Lynn. During hypnosis, people are more open to the [suggestions of the hypnotherapist](https://www.youtube.com/watch?v=qlm4owCjqZI), whether those ask the patient to detach themselves from a past painful experience or visualize a solution to their problem. For some people, these changes may be catalyzed in a one- or two-hour session. For others, hypnotherapy or self-hypnosis may be a regular part of their mental health care. “Hypnosis can modify consciousness in many ways,” Lynn says. This state of deep relaxation isn’t particularly difficult for most people to dive into or emerge from. It’s similar to a [“flow state](https://time.com/56809/the-science-of-peak-human-performance/),” Spiegel says, or an altered state of consciousness in which a person is so immersed in a given activity, their focus narrows and their sense of time shifts. It’s also reminiscent of what happens during meditation, except instead of training people to tune into the present moment, hypnosis makes them [more receptive to suggestion](https://www.psychologytoday.com/us/blog/understanding-hypnosis/202111/what-s-the-difference-between-hypnosis-and-meditation). Like meditation practice, many people are capable of doing hypnosis on their own, Spiegel says. In 2020, he co-founded [Reveri](https://www.reveri.com/), a subscription-based self-hypnosis app that’s structured a lot like Calm or Headspace. A user can access recordings that guide them into a hypnotized state, after which they’re given suggestions or statements that lead them toward a goal the person selects before the session. “We do it all the time,” Spiegel says of entering and exiting these mental states, “but in hypnosis you do it more.” Brain-imaging studies have helped to illuminate what happens inside the hypnotized brain, though much still remains a mystery. During hypnosis, activity in a brain region that helps people switch between tasks [quiets down](https://www.nature.com/articles/s41598-021-84954-8), Spiegel says. This same region seems to [disconnect](https://academic.oup.com/cercor/article/27/8/4083/3056452) from another area responsible for self-reflection and daydreaming—which may be why hypnotized people aren’t worried about who they are or what they’re doing. Researchers have also found that hypnosis can calm brain regions that help control [autonomic functions](https://www.tandfonline.com/doi/full/10.1080/00029157.2021.1873099) like heart rate, blood flow, and breathing. This is likely what leads to the physical relaxation that’s a hallmark of hypnosis, Spiegel says. One of the most interesting modern applications of hypnosis is in the operating room, says [Lorenzo Cohen](https://faculty.mdanderson.org/profiles/lorenzo%5Fcohen.html), director of the Integrative Medicine Program at the University of Texas MD Anderson Cancer Center. For some localized breast cancer surgeries, namely lumpectomies, the center lets patients choose between general anesthesia or a localized anesthetic and hypnotherapy. Those who choose the second option remain fully awake during their surgery, but a hypnotherapist first helps them enter a state of deep relaxation, or “[hypnosedation](https://www.tmc.edu/news/2018/03/hypnosis-operating-room/),” Cohen says. “The local \[anesthesia\] should be doing its thing,” Cohen says. “The rest is in your head.” More than 30 clinical trials have affirmed the use of hypnosedation, says Cohen (who is also researching the practice). Studies have shown that people who received hypnosedation experienced less preoperative [anxiety](https://pubmed.ncbi.nlm.nih.gov/20099953/), required [less pain medication](https://academic.oup.com/jnci/article/99/17/1280/2522362) during surgery, and reported less post-operative [pain intensity](https://academic.oup.com/jnci/article/99/17/1280/2522362?login=false), nausea, fatigue, and discomfort than people who chose general anesthesia, Cohen says. “The hypothesis is that the patients who are under general anesthesia, even though they’re not conscious, are having an intense stress response,” he says. This can suppress an immune system that, in cancer patients, is already compromised by the disease and its treatments. When patients choose hypnosis, Cohen believes the body’s fight-or-flight response may be reduced. Despite the mounting evidence, hypnosis is not without skeptics. Randomized controlled trials have found that hypnosis can help with pain and anxiety associated with a range of medical conditions, but even the best studies can’t meet the gold-standard of a double-blind design, Spiegel says. While patients and practitioners can be kept in the dark about what pill they’re administering or receiving, it’s almost impossible to design a study where neither side knows hypnosis is being delivered, he adds. And historically, the power of hypnosis hasn’t always been wielded responsibly. The imaginative potential of hypnosis has been shown to create false memories—sometimes with devastating effects. At least [27 states](https://www.theguardian.com/science/2019/oct/04/false-witness-us-using-hypnosis-convict-criminals) ban hypnotically-elicited testimony from appearing in court. Hypnotherapists should avoid using the technique to “recover” memories, Lynn says. But when conducted by a trained professional and properly applied, modern hypnotherapy can provide powerful results. Susceptibility to suggestion is often “viewed as a liability or a weakness,” Spiegel says, “but it’s really a strength.” ## Transcript [00:00] For mental health issues you might be avoiding right now. [00:03] One, you don't have the life you had before the pandemic. [00:06] You never will again. [00:07] When the pandemic was happening and everyone was experiencing [00:11] lots of like mental health issues, it [00:12] put a spotlight on mental health creators that were posting online. [00:17] You can't love someone else until you love yourself as bullsht. [00:20] Because one end implies that people with low self-esteem [00:23] or mental health issues are incapable of loving others. [00:27] Just so. [00:27] With that, I have a disclaimer on my, you know, TikTok and Instagram [00:32] that this is not therapy [00:33] or my mental health pics are not specifically tailored to you. [00:36] Sure, I'm a licensed therapist, but I'm not your lessons therapist. [00:40] All the online spaces where I share content. Yes. [00:43] Even those livestreams where you shoot me questions are not therapy sessions, [00:47] so I want [00:48] somebody to like taking my content and then think about it and analyze it. [00:58] Therapy speak is a new way of saying psychobabble. [01:01] They're usually more like vulnerable words that talk about [01:05] like the primary emotions that you're experiencing. [01:19] But there's other ways that people are using that language, hurt people [01:23] or manipulate people or control people or sort of like shut down [01:27] conversations. [01:33] There's a difference [01:34] between selfishness and grandiosity and narcissism. [01:38] It's very rare [01:40] that you would be diagnosed with a narcissistic personality disorder. [01:44] They tend to believe everything [01:45] is everyone else's fault, and it comes out of early childhood. [01:49] There is a stage of development where your ego is separate [01:52] from other people's ego, and you're able to see that both of those are important. [01:57] Something is wrong and that development and it leads someone [02:01] having a really hard time seeing other people's needs as important as their own. [02:10] Gaslighting is a pretty [02:12] popular term these days, and what it means is somebody is trying [02:16] to manipulate you into believing in a reality that's not true. [02:22] But sometimes people are like, What? You're disagreeing with me. [02:25] You're not validating my experience, you're gaslighting me, [02:29] which is not actually what they're doing. [02:30] So if you say that somebody is a gaslighter, that can be like [02:34] a pretty incendiary accusation. [02:37] You and [02:41] I think that everybody should clearly express [02:43] what their boundaries are in relationships. [02:45] It's sort of like a blueprint that you'll offer somebody. [02:48] So a healthy boundary that somebody might create is I'm [02:51] not going to continue talking to you if you start to yell at me [02:55] a different way to use boundaries. [02:57] That's not exactly correct is to try to control somebody's [03:00] behavior and manipulate somebody's behavior. [03:02] You're allowed to say, I don't want to go to dinner, right? [03:06] That's a boundary. [03:07] But to be like, you know, well, I'll go if you go to this kind of place, [03:11] but I'm not going to go [03:12] if you go to this kind of place and you can't tell me, [03:13] I can't because I'm allowed to set boundaries. [03:16] Right. You're now like over stating it. [03:19] Five small but very brave green flags in a relationship. [03:22] One you sense their connection with you throughout the day. [03:25] We keep talking for decades and decades and decades in the field [03:29] of how we can improve mental health. [03:31] And the reality is, is that the way you improve anything is with education. [03:35] Therapists and Instagram and YouTube could do a better job [03:38] at verifying their licenses and degrees and trainings that therapists have. [03:44] And if therapists and mental health professionals [03:46] didn't have to talk about things in coded ways like eating disorders [03:50] or social justice or anxiety [03:53] or depression or suicidality, then I think that [03:58] there could be like some really good education happening online. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6171844/how-hypnosis-works/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6171844/how-hypnosis-works/"},"headline":"How Hypnosis Works, According to Science","datePublished":"2022-04-28T18:37:27.000Z","dateModified":"2026-02-24T14:11:33.854Z","description":"The practice helps people enter into a unique state of consciousness","url":"https://time.com/6171844/how-hypnosis-works/","keywords":["Mental Health","freelance","healthscienceclimate"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9a013b4bba191607/698a315eb3fce33ea30c9335/woman-on-beach.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Eleanor Cummins","jobTitle":null,"url":"https://time.com/author/eleanor-cummins/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9a013b4bba191607/698a315eb3fce33ea30c9335/woman-on-beach.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"woman-on-beach","caption":"woman-on-beach","creditText":"Rachen Buosa—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/tag/mental-health/","name":"Mental Health"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/6171844/how-hypnosis-works/","name":"How Hypnosis Works, According to Science"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Therapists Raise Red Flags About Using 'Therapy Speak' Online","description":"The classic vision of therapy revolved around a person on a couch, supine, tapping into their deepest and darkest hopes and fears.
