Clinical hypnosis for hot flashes

Clinical hypnosis is a mind-body therapy delivered by a trained clinician over about five weekly sessions, with daily self-practice at home. It is one of only two behavioral treatments, alongside CBT, that The Menopause Society recommends for hot flashes with Level I evidence. In its best trial, it reduced hot flashes by about three-quarters, far more than an active control, and improved sleep.

What it is and how it works

Clinical hypnosis involves a deeply relaxed state combined with focused attention, individualized mental imagery, and therapeutic suggestion. It has a long history in managing pain and anxiety. For hot flashes, the protocol developed at Baylor University by Gary Elkins uses:

• A hypnotic induction to reach a calm, absorbed state.
• Imagery chosen with the participant, typically of coolness and safety: walking in snow, a cool breeze, cold water.
• Suggestions for reduced perception of heat, improved sleep, and a sense of control.
• Self-hypnosis practice at home between visits.

The mechanism is not fully established. Hot flashes begin with a narrowed thermoneutral zone in the hypothalamus; hypnosis may act on the autonomic nervous system and on how the brain interprets the heat signal. Whatever the route, the 2013 trial measured hot flashes both by diary and by physiological monitoring, and both fell.

What the evidence shows

The 2013 Baylor trial. This randomized, single-blind trial enrolled 187 postmenopausal women having at least seven hot flashes a day (or 50 a week). Half received five weekly clinical hypnosis sessions; half received a structured-attention control that matched the time, attentive listening, discussion of symptoms, and encouragement from a trained clinician, but without hypnotic induction or cooling suggestions. At 12 weeks:

• Self-reported hot flash frequency fell by 55.8 flashes a week (74%) with hypnosis versus 12.9 (17%) with control.
• Hot flash score (frequency times severity) fell 80% versus 15%.
• Physiologically monitored hot flashes fell 57% versus 10%.
• Hot flash interference, sleep quality, and treatment satisfaction were all significantly better with hypnosis.

A follow-up analysis cited by the position statement found that the effect was not related to participants’ expectations about whether hypnosis would work.

The 2008 breast cancer survivor trial. Sixty women with a history of breast cancer and at least 14 hot flashes a week were randomized to five weekly hypnosis sessions or no treatment. Hot flash scores fell 68% from baseline in the hypnosis group, with significant improvements in anxiety, depression, interference, and sleep compared with controls.

How strong is this? The 2013 trial is well designed: randomized, with an active control that rules out the effect of simply receiving attention, and with physiological as well as self-reported outcomes. In percentage terms its results are larger than those reported in SSRI or gabapentin trials, although trials with different designs cannot be compared directly. The weakness is replication: both trials come from one research group, the 2008 trial used a no-treatment control, and no independent large trial has repeated the result. The position statement rates the body of evidence Level I and recommends it, while describing hypnosis as having been studied in “two trials.”

How it is delivered and how long it takes

The tested protocol is five weekly in-person sessions with a trained clinician, plus at-home self-hypnosis practice. Benefit built over weeks 2 to 6 and was measured at week 12. The position statement notes the program can be delivered by a trained provider or accessed through a smartphone application.

Hypnosis is sometimes combined with CBT-based elements. The two approaches overlap in psychoeducation and relaxation but differ in the use of hypnotic induction and imagery.

Side effects and who it may not suit

The trial reports reviewed here do not describe safety problems with hypnosis. Hypnosis is not mind control; you stay aware throughout. If you have a mental health condition or a trauma history, mention it so the clinician can decide whether hypnosis fits and adapt the imagery. Hypnosis treats the symptom experience; it does not address bone loss, vaginal symptoms, or other consequences of low estrogen.

Cost and access in the US

There is no standard price. When a licensed psychologist, physician, or other licensed clinician provides it, sessions may be billed as behavioral health visits; coverage depends on your plan. Not everyone who advertises hypnosis is a licensed health professional, so for a medical symptom, look for a licensed clinician with hypnosis training through a recognized body such as the American Society of Clinical Hypnosis or the Society for Clinical and Experimental Hypnosis. Ask whether they use a hot-flash-specific protocol and what their experience with menopausal patients is.

How it compares with other options

Option	Reduction in hot flashes	Control type	Other benefits	Main limitation
Clinical hypnosis	74% vs 17% (self-report); 57% vs 10% (physiological)	Active attention control	Sleep, interference	Few trials, one research group
CBT	Small effect on count	Usual care or waitlist	Bother, sleep, mood	Does not lower frequency much
SSRIs/SNRIs	About 1 to 2 fewer/day vs placebo	Placebo	Mood	Side effects
Gabapentin	45% vs 29% placebo at 900 mg	Placebo	Sleep (sedation)	Drowsiness
Fezolinetant	About 2.5 fewer/day vs placebo	Placebo	Early onset	Liver tests, cost
Hormone therapy	Most effective overall	Placebo	Bone, vaginal symptoms	Contraindications

Percentages across trials are not directly comparable because the populations and controls differ. Hypnosis is a reasonable first choice for women who want to avoid medication, who have had side effects from drugs, or who are breast cancer survivors seeking a non-pharmacological option. It can also be added to a medication.

Questions for your clinician

• Do you know a licensed clinician trained in clinical hypnosis for hot flashes, or a program that follows the tested five-session protocol?
• Would hypnosis be billed as a behavioral health visit under my plan?
• Can I start hypnosis while continuing or trialing a medication?
• If I have a trauma history, how will the imagery be adapted?
