Using Hypnosis to Enhance Health & Performance | Dr. David Spiegel

Spiegel defines hypnosis as narrowing attention “like a telephoto lens” where experience is vivid but context and self‑evaluation are reduced. Neural imaging shows decreased activity in the dorsal anterior cingulate (less conflict monitoring and distraction), altered connectivity between the dorsolateral prefrontal cortex and insula (greater top‑down influence on bodily states), and inverse connectivity between DLPFC and posterior cingulate (reduced self‑referential rumination). This supports deep absorption, cognitive flexibility, and dissociation from the usual self‑story—all of which can be harnessed therapeutically.

Roughly one-third of adults are low in hypnotizability, two-thirds are responsive, and ~15% are highly hypnotizable. Longitudinal Stanford data show hypnotizability is remarkably stable over 25 years (test–retest correlation ~0.7—higher than IQ). You can’t reliably “train” someone from low to high hypnotizability; instead, assess their level and match expectations and techniques to that capacity. The Spiegel eye‑roll test is a quick screening tool: the more sclera visible when closing the eyelids while looking up, the higher the hypnotizability tends to be.

In a randomized trial of patients undergoing arterial interventions, those taught self‑hypnosis had ~80% less pain after 90 minutes, used about half the opioids, had fewer complications, and cut procedure time by ~17 minutes compared to standard care. Anxiety essentially dropped to zero in the hypnosis group while remaining moderate in controls. Similar approaches in metastatic breast cancer halved pain over a year on very low medication doses, because patients learned to reframe and modulate pain signals rather than automatically reacting to them as new threats.

Spiegel repeatedly stresses that avoidance and “trigger protection” often prolong suffering. Effective treatment entails safely re‑entering traumatic or frightening material, but from a position of control: dissociating bodily distress from the mental image, floating the body in a safe place, and viewing the event on a “mental screen.” This allows people to reinterpret their role (e.g., recognizing survival behaviors) and build new associative networks that are not exclusively fear-based. He notes data showing adding hypnosis to PTSD treatments improves outcomes.

Spiegel describes teaching patients a few core scripts (floating imagery, screen imagery, altering temperature/ sensation) then having them practice on their own. Old‑school, he’d have them record sessions on their phones; now the Reveri app delivers structured 15‑minute sessions plus 1–2‑minute refreshers. Early data from Reveri show about two‑thirds of users feel better even after a one‑minute refresher, and randomized trials for sleep, stress, and pain show durable benefits. You typically know in a single session whether hypnosis will help you.
