You're in a meeting, mid-sentence, and the heat starts at your chest and climbs straight up your neck. Now imagine that part of how you handle it is picturing a cold mountain stream you've practiced imagining every day for six weeks. It sounds a little woo. It also has better clinical trial data behind it than most of the supplements sold in the menopause aisle.
So, what is self hypnosis, really? Let's clear out the purple capes first.
What is self hypnosis (and what it definitely isn't)
Mayo Clinic describes hypnosis as a changed state of awareness with deep relaxation and sharper focus, usually guided by a trained professional using repetition and mental images. Once you're relaxed, the guide makes suggestions toward a goal, like easing pain or reducing cravings.
What it isn't: mind control. You don't lose control of your behavior, and you usually stay aware and remember the session afterward. Nobody is making you cluck like a chicken. Stanford researcher David Spiegel put it this way: hypnosis is the oldest Western form of psychotherapy, 'but it's been tarred with the brush of dangling watches and purple capes.'
Self hypnosis is the same idea, minus the person in the room. You guide yourself into that focused, relaxed state, often with an audio recording, and use imagery or a short phrase tied to your goal. Mayo notes that with practice, many people can get there on their own.
What's happening in your brain
In a 2016 study published in Cerebral Cortex, Spiegel's team screened 545 people and brain-scanned 57 of them: 36 who were highly hypnotizable and 21 who barely responded to hypnosis at all. Only the highly hypnotizable group showed three changes during hypnosis. Activity dropped in a region involved in deciding what deserves your attention (part of the dorsal anterior cingulate). Connection increased between a planning region and the insula, which helps the brain track what's going on in the body. And connection decreased between that planning region and the network that runs when your mind wanders.
In Spiegel's words, 'In hypnosis, you're so absorbed that you're not worrying about anything else.' According to the Stanford team, roughly a tenth of people are highly hypnotizable. Most people fall somewhere in the middle, which is a fair reminder that results vary from person to person.
The hot flash research
This is the part that matters most for us, and the research is surprisingly solid for a mind-body practice.
In a trial published in the journal Menopause, Gary Elkins and colleagues at Baylor University randomly assigned 187 postmenopausal women who were having at least seven hot flashes a day to either five weekly sessions of clinical hypnosis or five weekly sessions of structured attention (time with a clinician talking about symptoms, without hypnosis). The hypnosis group also practiced daily at home with an audio recording, choosing imagery of coolness, a safe place or relaxation. After 12 weeks, hot flash frequency dropped 74 percent in the hypnosis group versus 17 percent in the comparison group. The researchers didn't rely on diaries alone; they also measured hot flashes with skin monitors, and no side effects were reported beyond temporary skin irritation from those monitors.
The newer study is the one that makes it practical. In a 2025 trial in JAMA Network Open, the same research group tested hypnosis with no therapist sessions at all. 250 postmenopausal women (average age about 56, with at least four hot flashes a day) listened to a 20-minute self-hypnosis recording daily for six weeks, built around relaxation and imagery of coolness. The comparison group got recordings of white noise labeled as hypnosis. At 12 weeks, hot flash scores in the hypnosis group were down about 61 percent. In the white noise group, they were down about 44 percent.
Look at that second number for a second. Forty-four percent from white noise. Expectation, attention and time all do a lot with hot flashes, which is exactly why studies need a fake version to compare against. Hypnosis still came out clearly ahead, especially for moderate hot flashes, which kept dropping in the hypnosis group while the white noise group leveled off. Mild side effects were rare and about equal in both groups (3.2 versus 4 percent). Nearly a quarter of participants had a history of breast cancer, a group that often can't use hormone therapy, and their hot flashes dropped 64 percent after six weeks.
The Menopause Society's 2023 position statement on nonhormone therapy recommends clinical hypnosis, along with cognitive behavioral therapy, for hot flashes. The same panel did not recommend paced breathing, yoga, mindfulness or general relaxation for them, which suggests the panel saw hypnosis as more than generic relaxation. The statement also says hormone therapy remains the most effective treatment for hot flashes. Hypnosis is a real option, especially for women who can't or don't want to use hormones, not a replacement everyone should choose.
What else self hypnosis might help with
The evidence elsewhere is more mixed. According to the National Center for Complementary and Integrative Health, gut-directed hypnotherapy may ease irritable bowel syndrome, and the American College of Gastroenterology recommends it, but conditionally and based on very low-quality evidence. Results for anxiety before medical or dental procedures look promising but aren't conclusive. Studies on quitting smoking have conflicting results. A growing body of research suggests it may help with some kinds of pain. It's a reasonable thing to try for stress and sleep, as long as you're realistic about the evidence.
How to try self hypnosis at home
The trials used professionally made recordings, and a reliable recording is the easiest place to start. If you'd rather try it on your own, here's a simplified version of the steps Cleveland Clinic outlines:
- Find a quiet spot where you won't be interrupted for 10 to 20 minutes. Sit or lie down comfortably.
- Pick one clear goal. For hot flashes, that might be 'my body feels cool and calm.'
- Breathe slowly. Let your eyelids feel heavier until they close.
- Tense and release your muscles from your toes up to your face.
- Picture a place that feels cool and safe, using every sense: the cold air on your skin, the sound of water, the color of the light.
- Repeat your phrase quietly to yourself a few times.
- Come back slowly. Wiggle your fingers and toes, then open your eyes.
Consistency mattered in the trials: the self-hypnosis study used daily practice for six weeks. One session isn't a fair test. If your mind wanders, that's normal; you just bring it back, the same way you would in meditation.
Who should be careful
When it's done by a trained therapist, hypnosis is considered safe, according to Mayo Clinic. Mayo also says it may not be safe for some people with severe mental illness, and rare side effects include headache, dizziness, nausea and anxiety. Cleveland Clinic suggests checking with a professional first if you have schizophrenia, a dissociative disorder, PTSD, recent significant trauma, a seizure disorder or another neurological condition, or if you're in severe emotional distress. And it advises caution about using hypnosis to dig into painful past events, since that can stir up strong reactions. Avoid recordings that promise to rewrite your past or make major life decisions for you.
If hot flashes are the reason you're here, start a simple log this week (how many, how strong, what was happening) before you try anything. It'll show you whether a new tool is helping, and it's the most useful thing you can bring to a menopause appointment.
