Hypnosis Is Not Losing Control

Contrary to popular fear, hypnosis does not involve losing control. Instead, it teaches people to gain greater control over their mind and body. Dr. Spiegel emphasizes that stage hypnosis, while dramatic, demonstrates a person's willingness to let go of fixed self-identity, not surrender to external control. In clinical settings, hypnosis is self-directed and empowers individuals to manage pain, anxiety, and behavior.

Hypnosis enhances, not diminishes, personal control over attention and bodily states.
Stage hypnosis shows people 'trying on' different identities, not being controlled.
All hypnosis is self-hypnosis; the clinician merely guides the process.
Patients report feeling more in control, not less, during and after sessions.

“The biggest fear and misunderstanding is that it's losing control. And I'm here to tell you that hypnosis is a way of teaching people how…”

Hypnosis Is the Rodney Dangerfield of Medicine

Dr. Spiegel argues that hypnosis is underused in mainstream medicine due to misunderstanding, fear, and economic forces. Doctors often dismiss 'talking' as ineffective compared to drugs or surgery. Meanwhile, pharmaceutical companies spend billions promoting medications, while hypnosis—despite strong evidence—lacks marketing muscle. He calls it 'the Rodney Dangerfield of treatments' because it 'gets no respect.'

Doctors undervalue non-pharmacological interventions.
Fear and misunderstanding surround hypnosis.
Pharma outspends hypnosis advocacy by orders of magnitude.
Despite evidence, it remains sidelined in medical training.

“We don't get no respect. You know, he—I don't know if you remember him. He was a comedian. He said, 'They asked me to leave…”

How Hypnosis Changes Your Brain

Dr. David Spiegel explains the three key brain changes during hypnosis using fMRI data. These include reduced activity in the dorsal anterior cingulate cortex (the brain's 'alarm system'), increased connectivity between the prefrontal cortex and insula (enhancing mind-body control), and reduced activity in the default mode network (which governs self-identity and expectations). Together, these shifts allow deeper focus, reduced anxiety, and greater control over bodily sensations.

Reduces activity in the dorsal anterior cingulate cortex, lowering the brain's 'alarm response' to distractions.
Increases functional connectivity between the prefrontal cortex and insula, improving mind-body control and interoception.
Suppresses the default mode network, reducing self-judgment and allowing 'trying on' new behaviors.
These changes explain why hypnosis reduces pain, stress, and enhances performance.

“The more hypnotized they are, the more they turn down activity in a part of the brain called the dorsal anterior cingulate cortex.”

The COMT Gene and Hypnotic Ability

Dr. Spiegel discusses research linking hypnotizability to the COMT gene, which regulates dopamine metabolism in the prefrontal cortex. People with the Val/Val variant (fast dopamine clearance) tend to be more hypnotizable, while those with Met/Met (slow clearance) are less so. This genetic insight helps explain individual differences in responsiveness to hypnosis and suggests a biological basis for the trait.

The COMT gene affects dopamine levels in the prefrontal cortex.
Val/Val genotype (fast clearance) is associated with higher hypnotizability.
Met/Met genotype (slow clearance) correlates with lower hypnotizability.
Dopamine regulation influences cognitive flexibility and stress response, key to hypnotic responsiveness.

“There's one gene that's very interesting. It's catechol-O-methyltransferase. It's involved in the metabolism of dopamine in the brain. And it is involved in hypnotizability.”

Self-Hypnosis for Natural Childbirth

Dr. Spiegel shares a personal story about his wife, Helen, who used self-hypnosis to give birth to both of their children without anesthesia. She wanted to remain in control of the process and trusted her body's ability to manage pain. This experience highlights how hypnosis can empower individuals during intense physical events by shifting their relationship to pain and fear.

Helen used self-hypnosis to manage labor pain without medication.
She prioritized control and presence over pain elimination.
Demonstrates hypnosis as a tool for natural, empowered childbirth.
Reflects broader applications for pain management without drugs.

“My lovely wife Helen had both of our children without anesthesia. She wanted to be in control. And I've talked with other women who said,…”

Healing Childhood Trauma with Hypnosis

Dr. Spiegel recounts treating a woman abused at age 12 who carried shame and depression for decades. In hypnosis, he guided her to imagine comforting her younger self as a mother would. This shift in perspective—toward self-compassion—broke her emotional paralysis. She emerged from therapy transformed, no longer depressed, and unrecognizable to friends.

Patient had chronic depression from childhood sexual abuse.
Hypnosis allowed her to reframe the event with self-compassion.
She visualized comforting her 12-year-old self as a mother.
Resulted in rapid, lasting emotional healing.

“I want you to answer one question for me. Is this her fault? And she started to cry harder and she said, 'No, I'm stroking…”

Hypnosis and Psychedelics: Similar Brain Effects

When asked about parallels between hypnosis and psychedelics, Dr. Spiegel confirms that both reduce activity in the default mode network—the brain system linked to self-identity and rumination. This shared mechanism may explain why both can produce profound shifts in perspective, ego dissolution, and therapeutic breakthroughs in trauma and depression.

Both hypnosis and psychedelics reduce default mode network activity.
This allows detachment from fixed self-narratives and shame.
The effect enables new perspectives on traumatic memories.
Hypnosis offers a non-chemical, controllable alternative.

“The reduction in default mode network activity happens with psychedelics. It happens with meditation too. So there is that common ground there.”

Revery App for Pain and Stress

Dr. Spiegel developed the Revery app, a digital tool based on clinical hypnosis, to help users manage pain, stress, and insomnia. The app guides users through self-hypnosis sessions that reduce somatic arousal and improve emotional regulation. It's clinically validated, with studies showing significant pain and stress reduction in minutes, even for those with low hypnotizability.

Revery uses evidence-based self-hypnosis techniques.
80% of users report reduced pain or stress within 10 minutes.
Effective for chronic pain, anxiety, and sleep onset.
Available on iOS, Android, and web (revery.com).

“We're seeing people getting immediate reductions in pain response. You can download it at revery.com from the web or from the app store.”

Cyclic Sighing for Rapid Calm

Dr. Spiegel introduces 'cyclic sighing'—a simple breathwork technique combining a double inhale through the nose followed by a slow exhale through the mouth. This method quickly activates the parasympathetic nervous system, reducing heart rate and promoting relaxation. It's integrated into the Revery app and can be used anytime for fast stress relief.

Inhale through nose (abdomen first, then chest), then slowly exhale through mouth.
Triggers parasympathetic 'rest and digest' response.
Can be done in under a minute for immediate regulation.
Part of Revery app's breathwork library.

“You do an abdominal inhale, through your nose about halfway. Now fill your lungs completely and then slowly exhale through your mouth.”

Single-Session Hypnosis to Quit Smoking

Dr. Spiegel's research shows that a single session of hypnosis—delivered in person or via app—can help one in four smokers quit. The key is not aversion ('cigarettes taste like horseshit') but affiliation: framing the body as something to protect. This positive reinforcement approach is as effective as pharmaceuticals like bupropion.

One session can lead to long-term smoking cessation.
Focuses on protecting the body, not disgust with cigarettes.
App-based delivery (Revery) is as effective as in-person.
One in four quit, half cut consumption by 50%.

“We got one out of four people to stop. Half stopped right away. Half of them had not touched a cigarette in a year.”
