Huberman LabDr. David Spiegel on Huberman Lab: How hypnosis rewires fear
Hypnosis narrows attention to separate thought from all feeling; Reveri protocols cut acute pain, ease stress, and speed relief from phobias and trauma.

WHAT IT’S REALLY ABOUT
Harness Hypnosis: Train Brain States To Transform Health And Performance
- Andrew Huberman and psychiatrist Dr. David Spiegel explore hypnosis as a scientific, trainable brain state of highly focused attention that can increase control over mind and body, rather than surrender it.
- They review brain networks involved in hypnosis, showing how changes in attention, self-referential processing, and mind–body connectivity enable powerful shifts in pain, stress, sleep, phobias, and trauma responses.
- Spiegel explains how clinical and self-hypnosis work in practice, including quick protocols, hypnotizability testing, and applications via the Reveri app, as well as indications, limitations, and safety considerations.
- The conversation emphasizes voluntary exposure to feared experiences in a controlled hypnotic state as a fast way to rewire associations, build cognitive and emotional flexibility, and enhance both everyday functioning and peak performance.
IDEAS WORTH REMEMBERING
5 ideasHypnosis is a state of concentrated, flexible attention that increases control.
Spiegel defines hypnosis as a state of highly focused attention, similar to being absorbed in a movie or a game. Contrary to stage myths, clinical and self-hypnosis enhance control over thoughts, emotions, and bodily responses by suspending habitual critical judgment and allowing new perspectives and responses to emerge.
Specific brain network changes underlie hypnotic effects on perception and the body.
During hypnosis, activity in the dorsal anterior cingulate cortex (a conflict and salience detector) decreases, reducing distraction. Functional connectivity increases between the dorsolateral prefrontal cortex (dlPFC) and the insula, strengthening top-down control of bodily states (e.g., gastric acid secretion). Inverse connectivity between dlPFC and the posterior cingulate (default mode) reduces self-referential thinking, enabling dissociation and cognitive flexibility.
Hypnosis can directly modulate physiological processes and symptoms like pain, stress, and sleep.
In highly hypnotizable individuals, hypnotic suggestions about imagined food altered gastric acid by +87% and −40%, and even reduced pentagastrin-induced secretion by 19%. Similar mind–body control is used clinically to decouple physical stress reactions from psychological stress, reduce chronic pain, and improve insomnia, often with brief daily self-hypnosis sessions or app-guided practices.
Effective trauma and phobia treatment often requires controlled re-exposure in a safe hypnotic state.
Spiegel describes hypnosis as a rapid way to help people reconfront traumatic memories while keeping the body relaxed and safe, then reframe the narrative (e.g., recognizing life-preserving actions during an assault). This leverages state-dependent memory: hypnosis approximates the dissociative state in which trauma occurred, making it easier to access, process, and update those memories and associations.
Not everyone is equally hypnotizable, and this shapes treatment strategy.
About one-third of adults are not hypnotizable, two-thirds are to varying degrees, and roughly 15% are highly hypnotizable. Hypnotizability can be quantified (0–10 scale) using structured tests and the Spiegel eye-roll test (observing eye position when closing eyelids while looking up). More obsessional/OCD individuals tend to be less hypnotizable, often because they over-evaluate instead of allowing immersive experience.
