Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance.

I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. And now for my discussion with Dr. David Spiegel. David, thank you so much for being here.

Andrew, my pleasure. Can you tell us what is hypnosis? Hypnosis is a state of highly

focused attention. It's something like looking through the telephoto lens of a camera in consciousness,

which you see you see with great detail, but devoid of context.

If you've had the experience of getting so caught up in a good movie that you forget,

you're watching a movie and enter the imagined world, you're part of the movie, not part of

If your physical reactions are distracting you or make you think about something else, that's when it's less hypnotic-like and more just one of a series of

experiences. I think for most people, when they hear hypnosis or they think about hypnosis,

they think of stage hypnosis. I think of somebody with a pendant going back and forth.

Could you contrast the sort of hypnosis that you do in the clinical setting with the sort of

hypnosis that a stage hypnotist does?

I don't like stage hypnosis. You're making fools out of people. And you're using the fact, and that's what scares people about hypnosis.

They think you're losing control. You're gaining control. Self-hypnosis is a way of enhancing your control over your mind and your body.
