- Welcome to the Huberman Lab Podcast,
[upbeat music]
where we discuss science,
and science based tools for everyday life.
I'm Andrew Huberman,
and I'm a professor of
neurobiology and ophthalmology,
at Stanford School of Medicine.
Today, my guest is Dr. David Spiegel.
Dr. Spiegel is the associate
chair of psychiatry,
and behavioral neurosciences,
at Stanford University School of Medicine.
He is also the director,
of the Stanford Center
on Stress and Health.
Dr. Spiegel is both a
researcher and a clinician,
meaning he runs a laboratory
that studies the brain,
and the body.
And neural mechanisms of how
the brain and body interact.
And he sees patients as a
psychiatrist at Stanford.
His work is incredibly unique,
in that it bridges mind and body,
but it also has a particular focus
on the clinical applications of hypnosis.
As you'll learn today,
hypnosis is a unique brain state,
in which neuroplasticity,
the brain's ability to change
in response to experience,
may be heightened and indeed
the use of clinical hypnosis,
by Dr. Spiegel and
colleagues has been shown
to improve symptoms of stress,
chronic anxiety, chronic pain
and various other illnesses,
including many psychiatric illnesses
and even outcomes in cancer.
Today, we discuss hypnosis in
the context of what's called,
self-hypnosis to distinguish
it from stage hypnosis.
Many of you are probably
familiar with stage hypnosis,
which is really about a
hypnotist getting a person
to do things they would not otherwise do,
in contrast, clinical hypnosis,
and the use of hypnosis for the treatment
of various ailments of mind
and body is vastly different.
It involves getting people
to change their brain state
and to use that brain state as a portal
to make adjustments in
their brain and body,
and other aspects of their
biology and psychology
that benefit them.
And it's been shown over and over again,
in studies by Dr. Spiegel and colleagues
that those changes can
occur extremely quickly.
Now, not everybody can be
hypnotized as readily as the next.
And so today we also
discuss a simple test,
developed by Dr. Spiegel.
The it can help you determine,
whether or not you have a
high, medium or low degree,
of what we call hypnotizability.
Dr. Spiegel is truly
an expert in this area.
He has published over
480 journal articles,
170 book chapters on hypnosis,
and on things like psychosocial oncology,
which is the interaction of mind and body
in the treatment of cancer
and cancer outcomes,
on stress physiology, trauma
and other aspects of psychotherapy.
He's published 13 books.
So, he's truly the world expert
in hypnosis and clinical
applications of hypnosis
for mind and body.
I'm certain that in
listening to today's episode,
you're going to learn a tremendous amount
about how the brain and body interact,
about various treatments
for all sorts of common
ailments of mind and body.
And you are going to get access to tools,
in particular, a tool that
was developed by Dr. Spiegel,
which is the Reveri app, R-E-V-E-R-I,
the Reveri app is currently
only available for Apple,
but will soon also be
available for Android.
It does carry a nominal cost,
but there is a seven day free trial.
If you'd like to try it,
we're providing a link in the show notes.
The Reveri app is special,
in that it is based on clinical studies
and research done in the
Spiegel lab at Stanford.
So, unlike a lot of
hypnosis apps out there
and resources for hypnosis,
it was developed with
clinical treatments in mind.
Today, we also discuss
the use of breathwork
and I'm very fortunate that
my research lab at Stanford,
has been collaborating very
closely with Dr. Spiegel
in testing and developing
specific breathwork protocols
to adjust mind and body
for things like anxiety,
improving mood and improving sleep.
Based on his incredible
and unique expertise,
and the clarity with which,
Dr. Spiegel communicates information.
I anticipate that you will
really enjoy today's episode
and that you'll come away from it,
with a lot of actionable tools.
Some of you might be curious,
what a clinical hypnosis
session looks like.
And for that reason, we had
Dr. Spiegel hypnotize me.
A clip of that hypnosis session,
is going to be posted to the
Huberman Lab Clips channel,
which is available on YouTube.
Before we begin, I'd like to
emphasize that this podcast
is separate from my teaching
and research roles at Stanford.
It is however, part of
my desire and effort
to bring zero cost to consumer
information about science
and science related tools
to the general public,
in keeping with that theme,
I'd like to thank the
sponsors of today's podcast.
Our first sponsor is Athletic Greens.
Athletic Greens is an all-in-one,
vitamin, mineral, probiotic drink.
I've been taking Athletic
Greens since 2012.
So, I'm delighted that they're
sponsoring the podcast.
The reason I started
taking Athletic Greens
and the reason I still
take Athletic Greens,
once or twice a day,
is that it covers all of my foundational,
vitamin, mineral, probiotic needs.
There is now ample evidence
that probiotics can be very helpful
for supporting what is
called the gut microbiome.
The gut microbiome is an
aspect of our biology in which,
little gut microbiota live all
along our digestive pathway
and help support various
aspects of our biology,
including our immune system,
our metabolic system,
our hormone or endocrine system,
as well as what's called
the gut brain access,
which is literally
communication between the gut
and the brain to support things like mood,
motivation and various other
aspects of brain health.
With Athletic Greens, I get the probiotics
that I need to support
a healthy gut microbiome
and the vitamins and minerals tap off,
any deficiencies I might have,
based on lack of certain foods
and lack of certain nutrients in my diet.
If you'd like to try Athletic Greens,
you can go to athleticgreens.com/huberman
to claim a special offer.
They give you five free travel packs,
plus a year supply of vitamin D3 K2.
There's a lot of evidence
now that vitamin D3
is critically important
for various aspects
of immediate and long term health.
And while many people
get enough vitamin D3,
many people do not.
So, the year supply of vitamin D3,
ought to be very useful for many people,
and K2 has been shown to be important for,
calcium regulation, various
aspects of metabolic health
and so forth.
So again, if you'd like
to try Athletic Greens
and get that special offer
of the five free travel packs
and a year supply of vitamin D3 K2,
go to athleticgreens.com/huberman
Today's episode is also
brought to us by Thesis.
Thesis makes custom nootropics,
a nootropic is a smart drug.
And personally, I'm not a big fan
of the concept of a smart drug.
At least not the way that
most people talk about,
smart drugs or nootropics,
for the following reason,
being smart involves various things.
There is creativity, there's focus,
there's task switching and so on.
And each one of those
involves different operations
in the brain, different neural circuits,
different neurochemicals
have to be deployed,
in order for us to, for
instance, be very focused
or for us to be very creative
or for us to be able
to switch tasks easily.
Thesis understands this
and for that reason,
they've developed custom nootropics,
that are aimed at getting
your brain and body
into particular states for
particular types of work
or physical activity.
In order to accomplish that,
they created unique blends
of high quality ingredients.
And each of those blends is designed
to get your brain and body
into a particular mode,
such as focus, clarity or motivation.
I've been using Thesis nootropics
for over six months now.
And I have to say it's
been a total game changer
and very unique from
the experience of using,
sort of what I call, catchall nootropics.
So with Thesis, it's really directed
toward particular brain-body states.
I should also mention
that they tailor those
custom blends to you.
So, by taking a quiz on their site,
they will tailor the blend to
you and your specific needs
and the things you don't want.
So, if you want to try your own,
personalized nootropics starter kit,
you can go online to
takethesis.com/huberman
you'll take a three minute quiz
and thesis will send you
four different formulas
to try in your first month.
And then based on the outcomes with those,
they can update your formulations for you.

Today's episode is also
brought to us by ROKA.
ROKA makes eyeglasses and sunglasses
that I believe are of the utmost quality.
The company was found by,
two All-American Swimmers from Stanford
and everything about the design
of ROKA eyeglasses and sunglasses,
was created with performance in mind.
There are a number of things about,
ROKA sunglasses and eyeglasses
that I particularly like,
first of all, they're
extremely lightweight.
You basically forget
that you're wearing them.
Second of all, you can wear them for work,
for going out to dinner, et cetera.
They have great aesthetics,
so you can wear them anywhere,
but also for exercise.
You can wear them when running or cycling,
and even if you get sweaty,
they're designed so that they
don't slip off your face.
Another terrific feature of
ROKA eyeglasses and sunglasses,
is that they were designed
with the biology of the
visual system in mind.
We all have the experience
of being in a shaded area
and then going to a bright area,
it takes some time for your
eyes to adjust or to adapt.
Many sunglasses make it hard to see
as you move from one
environment to the next
and therefore, you have to take
on and off your sunglasses,
with ROKA sunglasses, you
don't have to do that.
You don't even notice the transitions
between those bright areas
and those dimer areas.
So, you can wear them anywhere, anytime.
And again, most of the time,
you don't even realize
that they're on your face.
If you'd like to try ROKA
eyeglasses and sunglasses,

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,
what 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 a enter the imaginary world.
You're part of the movie,
not part of the audience,
you're experiencing it,
you're not evaluating it.
That's a hypnotic like experience
that many people have
in their everyday lives.
- So, is any experience
that really draws us in,
hypnotic in that sense?
Or let me give a different example.
If I'm watching a sports game
and I'm really wrapped up in the game,
but I'm also in touch with how
it makes me feel in my body
kind of registering the
excitement or the anticipation.
Is that a state of hypnosis also,
because you mentioned there's kind of,
a narrowing of context.
- Right.
- But a kind of losing of the self,
or is it, do I have that right?
- Yes, it is true that you're-
[indistinct] to the extent
that you're somatic,
your body experience is
a part of the sport event
that you're engaged with.
I'd say that is a self
altering hypnotic experience.
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.
- Okay.
So I have to ask,
how did you get into this
business of hypnosis?
Because,
I think for most people,
when they hear hypnosis or
they think about hypnosis,
they think of stage hypnosis.
- Right.
- They think of somebody with
a pendant going back and forth
or people up on a stage,
behaving abnormally for the
entertainment of others.
- Yeah.
- How did you get into hypnosis
as an interest, as a practice?
And if you would,
could you contrast the sort
of hypnosis that you do
in the clinical setting
with a sort of hypnosis
that a stage hypnotist does?
- Sure.
Well, it is something of a
genetic illness in my family.
Both of my parents were
psychiatrists and psychoanalysts
and they told me I was free
to be any kind of
psychiatrist I wanted to be.
So, here I am.
My father was training to
be a psychoanalyst in 1943.
And,
he ran into a Vietnamese refugee,
who couldn't serve in the army,
but who had studied hypnosis.
And actually it would interest you,
doing your ophthalmological research.
He had a smallpox scar right
in the middle of his forehead,
and he did forensic examinations.
And he noticed that some of the prisoners,
would focus on that spot on his forehead
and then close their eyes
and seem to go to sleep.
But they were in some altered state.
So he got interested in hypnosis.
He used it forensically
and his name was Gustav von Aschaffenburg.
And he offered to teach
young psychiatrists,
how to use hypnosis when
they went off into the war.
And so he trained my father
and my got off the
analytic couch and asked,
the analyst mentioned it to him.
That's how he found out about it.
And my father said, did I say
something wrong in analysis?
Why is he talking to me [laughs] now?
And he found it very
useful in helping soldiers
who had acute pain when they were wounded
and helping people with conversion
in post-traumatic stress disorders.
And when he came back, he
went back to his training,
but he still was sort of interested in it.
And he had his, one of his supervisors
was Frieda Fromm-Reichmann,
who was a very famous psychoanalyst.
And he said that he had been
told to stop doing hypnosis
because it would ruin his
reputation as an analyst.
And she said to him,
what are you so worried of
about your reputation for?
You're going to give a course
at the institute in hypnosis,
and I know you're going to do
it because I'm going to take it.
So he was teaching Frieda
Fromm-Reichmann hypnosis,
and he just kept doing it.
And after a while,
he discovered that he was
getting better results
with a few sessions of hypnosis
than he was with daily
psychoanalysis with his patients.
And so he switched his practice.
And so the dinner table conversations,
were pretty interesting.
And occasionally when he was
making a movie of a patient,
I would get to watch that.
And so, when I went to medical school,
I figured I'll take a course.
[mumbles] Tom Hackett,
who was a chair of psychiatry
of mass general was teaching
and it was a very interesting course.
And the day that converted me was,
I was doing my rotation at
Children's Hospital in Boston.
And the nurse is telling me,
Spiegel, your next patient is an asthmatic
in room 437 or something.
And I'm just following,
the sound of the wheezes down the hall.
I go in the room, there's
a 16 year old girl,
knuckles white, bolt upright
in bed, struggling for breath.
You can hear the wheezing.
She twice had subcutaneous
epinephrine, didn't work.
They were thinking
about general anesthesia
and starting her on steroids.
And her mother's there crying.
And I said, I don't know what else to do.
So I said, you want to
learn a breathing exercise?
And she nods.
And I got her hypnotized.
And then I realized we
hadn't gotten to asthma
in the course yet.
So, I made up something very complex.
I said, each breath you
take will be a little deeper
and a little easier.
And within five minutes,
she's lying back in bed.
Her knuckles aren't
white, she's not wheezing.
Her mother stopped crying.
The nurse ran out of the room,
and the intern, my intern comes to find me
and I figured he is going to
pat me on the back and say,
nice job, Spiegel.
He said, the nurse has filed a complaint
with a nursing supervisor
that you violated a
Massachusetts law by hypnotizing,
a minor without parental consent.
And I thought, oh, that's nice.
I doubt there is a law like this.
So, the interns says,
you're going to have to
stop doing this with her.
And I said, why?
He said, it's dangerous.
I said, you're going to
give her general anesthesia
and put her on steroids,
and talking to her is dangerous?
He said, well, you'll have to do it.
And I said, I'll tell you what,
take me off the case if you want,
but I'm not going to
tell a patient of mine,
anything I know is not true.
So, there was a battle over
the weekend about what to do,
and the intern, the chief
resident, the attending,
were all arguing about it.
And on Monday they came
back with a radical idea.
They said, let's ask the patient.
I don't think this has ever been done
at children's [chuckles] hospital before.
And she said, oh, I like this.
She'd been hospitalized every month
for three months in status asthmaticus,
she did a one subsequent
hospitalization but after that,
went on to study to be
a respiratory therapist.
And I thought that anything,
that can help a patient that much,
violate a nonexistent Massachusetts law,
frustrate the nursing supervisor,
had to be worth looking into.
So, I just kept doing it.
I discovered that there were,
all of my classmates in medical school,
had just read the new issue
of the New England Journal
and had some new medication to suggest.
And I would, you know,
surgeons would say, look,
if you can help this guy
with his pain or his anxiety,
anything above the neck,
that's yours, do it, Spiegel.
So, I was having fun and being able
to learn how to help people
in a way that just otherwise
was not being done.
And so, it got me thinking
about the fact that,
we're born with this brain
but we don't have a user's manual for it.
And we don't use it
nearly as well as we can.
And that's something your
research is all about too.
And so, I thought,
I want to understand this better.
And I want to see what we can do.
Stage hypnotists drive me nuts.
They make fools out of people.
There was one.
This is a case my father was involved.
He got a call from, he was
at Columbia, he got a call,
Spiegel, you got to come see
this woman, she's in the ER.
And she's in some kind of weird
upset state that happened.
And it turned out she'd been on the show
with a stage hypnotist who,
and what they do by the way is,
they cycle around, you know,
The beginning of the show,
they don't just grab somebody
and say, we're doing this.
They get a bunch of people up.
They do what [indistinct] testing,
to see if people-
and they get the ones who
are the most hypnotizable.
So she was the one.
And he said, there's now a
little bird in your hand,
and you're going to play with the bird.
And she starts to cry and scream.
And he just gets her off the stage,
'cause it's very upsetting.
And she's wandering around New York City
in the middle of the night dissociated
and brought to Columbia.
And that's where my father saw her.
She was still in a kind of
uncomfortable trance like state.
And it turned out,
that she was the trophy
wife of a very wealthy guy.
And she felt like a bird in a gilded cage.
And so to her,
that image just triggered
all of this sense of,
dissatisfaction and discomfort,
fear about her life.
And he was able to get her
reoriented and talk with her
about what she was going to of her life.
But 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.
It can work very well,
but because it gives you a
kind of cognitive flexibility,
you're able to shift sets very easily.
To give up judging and
evaluating the way you usually do
and see something from a
different point of view.
That's a great therapeutic opportunity,
but if misused, it could be a danger too,
and that's what scares people about it.
It is that very ability to
suspend critical judgment
and just have an experience
and see what happens.
That can be a great
therapeutic opportunity,
but if somebody's misusing it,
it can be a way to harm people.
And there are plenty
of examples of people,
having fantasies imposed on them,
that they come to think are realities.
It's not unusual these days.
So,
it's an ability that,
if people learn to
recognize and understand it,
can be a tremendous therapeutic tool.
- I've been stage hypnotized
and I've been clinically
hypnotized many times
through a self-hypnosis app.
We'll talk about later.
And then I know we have plans
for you to hypnotize me today.
You've done it once before.
- Mm-hm.
- [Andrew] And I'm very hypnotizable
as we both know.
- Right.
- We'll talk about,
how one can gauge their hypnotizability.
- Sure.
- But the stage hypnosis,
was interesting.
This was in college,
they brought someone out to the dormitory
and,
I recall being one of the people
that was selected.
- Mm-hm.
- And engaging in very
bizarre behavior, right?
It wasn't thoroughly embarrassing,
but it was pretty embarrassing.
And then being sent off the stage,
and as I was exiting,
suddenly screaming something out
because he had planted a
suggestion of some sort.
- Ah, mm-hm.
- And then I was told
to look in my pocket and there was,
like a, I think, a torn up dollar bill.
There were a bunch of things
that I have vague recollection of.
- Mm-hm.
But it raises set of questions
that really boil down to,
as a biologist, I always think that,
there's no events in the
brain, there are processes.
And so hypnosis, we know has an induction.
Then one is hypnotized, I imagine.
And then it sounds like this woman
and this example of the bird
and being distraught in New York City,
is a failure to exit the hypnotic state.
Do we know what sorts of
brain areas are active
during the induction,
let's call it the deep hypnosis
and then what's shutting off
or changing as people exit hypnosis.
- Yes, we do, we've studied that.
We've been very interested in that.
And so, we did a study
where we selected highly
and non-hypnotizable people
so we could do the comparison.
And then hypnotize them in
the functional MRI scanner.
And we found three things
characterized the entry
into the hypnotic state.
The first is turning down activity
in the dorsal anterior cingulate cortex.
So the DACC is in the central
front-middle part of the brain
as you well know.
And it's part of what we
call the salience network.
It's a conflict detector.
So if you're engaged in work
and you hear a loud noise
that you think might be a gunshot,
that's your anterior
cingulate cortex saying,
hey, wait a minute,
there's some potential danger over there.
You better pay attention to it.
So, it compares what you're doing
with what else is going on
and helps you decide what to do.
And as you can imagine,
turning down activity in that region,
make it less likely that
you'll be distracted
and pulled out of whatever you're in.
And in another study,
we found that highly hypnotizable people,
even without being hypnotized,
have more functional
connectivity between the DACC,
the anterior cingulate cortex
and the left dorsolateral
prefrontal cortex.
So, which is part of a key region
in the executive control network.
So, when you're engaging in tasks,
you're enacting a plan,
you're writing a paper, you're
doing whatever you're doing.
That's the prefrontal
cortex who's doing that.
And so, if that is coordinated,
we found more functional connectivity.
So, when one is up, the other's up
and one is down, the other's down.
That coordination implies
that the brain is saying,
okay, go ahead, I know what you're doing.
Carry out that plan.
And don't worry about other possibilities.
So, two other things happen
when people are hypnotized.
One is that that DLPFC has
higher functional connectivity
with the insula.
Another part of the salience network.
It's a part of the
mind-body control system,
sensitive to what's happening in the body.
It's part of the pain network as well,
but it's also a region of the brain where,
you can control things in your body
that you wouldn't have think you could.
For example, we did a study years ago,
where we took people who
were highly hypnotizable,
hypnotized them and told them,
we went on a imaginary culinary tour.
So, they would eat their
favorite foods and we found that,
they increased their gastric
acid secretion, like by 87%.
So, their stomach was acting
as though it was about to get,
I mean, there was one woman,
it was so vivid for her that
halfway through, she said,
let's stop, I'm full, [laughs]
eating these imaginary-
- Having never eaten-
- Having never eaten anything-
- Actual food?
- No.
- Incredible.
- And then we got them
to relax and think of
anything but food or drink.
And we got like a 40% decrease
in gastric acid secretions.
And that was DLPFC through the insula,
telling the stomach you're getting food
or you're not getting food.
And even, we injected
them with Pentagastrin,
which triggers gastric acid release.
And even then in the hypnosis condition,
they had a 19% reduction in gastric acid.
So, the brain has this amazing ability
to control what's going on in the body
in ways that we don't think
we have ability to control.
That's just one example.
So, that's the DLPFC insula connection.
The third thing that happens,
and this relates to what
you did on the stage,
is you have inverse
functional connectivity
between the DLPFC and the
posterior cingulate cortex.
The posterior cingulate is part
of the default mode network.
It's in the back of the brain.
And it's an area whose
activity goes down for example,
in meditators.
And in meditation, you're
supposed to be selfless.
You're supposed to, [indistinct]
self is an illusion,
you're supposed to let it dissolve
and just experience things.
And when you're doing that,
the posterior cingulate
is decreasing in activity,
the inverse connection is,
I'm doing something
but I'm not thinking about
what it means for me.
I may not even remember much of it.
if I do, I don't care that much about it.
And so, that is part of the dissociation
that I occur with hypnosis.
So, it's how you put things
outside of conscious awareness,
and don't worry about what it means.
It also adds to cognitive flexibility.
If you're thinking,
well, people like me
don't usually do this.
That may inhibit you from,
enacting a new form of
psychotherapy for example,
that you've never done before.
But if you're having
this decreased activity
in the part of your brain that
reflects on what it means,
you're more likely to
be cognitively flexible
and willing to give it a try.
And that's one of the
therapeutic advantages
of hypnosis as well.
- Fascinating, and it's really,
I'm going to embarrass
you here a little bit.
[David laughing]
In the positive sense,
your laboratory is really the one
that's pioneered brain
imaging of hypnotic states.
And, it sounds like it,
that's my understanding, is that correct?
- Yeah, I mean, there are other people,
who've done excellent research too.
- Sure.
Pierre Rainville in Montreal
and several other people,
but we're one of the leading labs
in neuroimaging of hypnosis.
- I have to ask about,
attention deficit hyperactivity disorder.
I get a lot of questions about this.
And I think a lot of people just struggle
with holding attention nowadays,
because of interference
with phones and devices.
And of course, there is a lot of,
clinically legitimate ADHD out there,
but the way that you describe,
- Sure.
- the dorsal anterior cingulate
and the salience network and
this a conflict detector of,
am I focusing on something or
am I splitting my attention?
How distractable am I?
Seems to relate to some extent to activity
in the anterior cingulate cortex.
Do people with ADHD,
display disruptions in
elements of these networks
and has hypnosis ever been used to,
or self-hypnosis, I should be,
to distinguish from stage hypnosis,
clinical and self-hypnosis been used
to enhance people's ability to focus
and hold attention?
Because that's such a built in component
of the hypnotic state.
- It's a great question.
There's sort of two
ways to think about it,
in terms of enhancing focus, yes.
It has been very helpful
in teaching people
to just prepare your mind
to narrow in and focus on something.
And when you're really
engaged in reading something,
or you're writing a pa-
I mean, I'll have that,
sometimes I'm thinking,
oh God, I have to do
this for another hour.
Other times an hour will
go by and I'll think,
hey, great, because when you're in that,
it feels game-like to you,
you're just assembling
the parts of the puzzle
and putting 'em together.
It's fun, you just get absorbed,
that for me, that's a
