Judson Brewer: A simple way to break a bad habit

November 18, 2015

Can we break bad habits by being more curious about them? Psychiatrist Judson Brewer studies the relationship between mindfulness and addiction -- from smoking to overeating to all those other things we do even though we know they're bad for us. Learn more about the mechanism of habit development and discover a simple but profound tactic that might help you beat your next urge to smoke, snack or check a text while driving.

When I was first learning to meditate,
00:12
the instruction was to simply
pay attention to my breath,
00:14
and when my mind wandered,
to bring it back.
00:17
Sounded simple enough.
00:20
Yet I'd sit on these silent retreats,
00:22
sweating through T-shirts
in the middle of winter.
00:25
I'd take naps every chance I got
because it was really hard work.
00:29
Actually, it was exhausting.
00:32
The instruction was simple enough
00:35
but I was missing something
really important.
00:36
So why is it so hard to pay attention?
00:40
Well, studies show
00:42
that even when we're really
trying to pay attention to something --
00:44
like maybe this talk --
00:47
at some point,
00:49
about half of us
will drift off into a daydream,
00:50
or have this urge
to check our Twitter feed.
00:52
So what's going on here?
00:56
It turns out that we're fighting one
of the most evolutionarily-conserved
00:58
learning processes
currently known in science,
01:02
one that's conserved
01:05
back to the most basic
nervous systems known to man.
01:06
This reward-based learning process
01:09
is called positive
and negative reinforcement,
01:11
and basically goes like this.
01:13
We see some food that looks good,
01:16
our brain says, "Calories! ... Survival!"
01:17
We eat the food, we taste it --
01:20
it tastes good.
01:21
And especially with sugar,
01:23
our bodies send a signal
to our brain that says,
01:24
"Remember what you're eating
and where you found it."
01:27
We lay down this context-dependent memory
01:31
and learn to repeat the process next time.
01:33
See food,
01:36
eat food, feel good,
01:37
repeat.
01:39
Trigger, behavior, reward.
01:40
Simple, right?
01:43
Well, after a while,
our creative brains say,
01:45
"You know what?
01:47
You can use this for more
than just remembering where food is.
01:49
You know, next time you feel bad,
01:52
why don't you try eating
something good so you'll feel better?"
01:54
We thank our brains for the great idea,
01:59
try this and quickly learn
02:01
that if we eat chocolate or ice cream
when we're mad or sad,
02:03
we feel better.
02:06
Same process,
02:08
just a different trigger.
02:09
Instead of this hunger signal
coming from our stomach,
02:11
this emotional signal -- feeling sad --
02:14
triggers that urge to eat.
02:16
Maybe in our teenage years,
02:18
we were a nerd at school,
02:21
and we see those rebel kids
outside smoking and we think,
02:23
"Hey, I want to be cool."
02:26
So we start smoking.
02:27
The Marlboro Man wasn't a dork,
and that was no accident.
02:29
See cool,
02:33
smoke to be cool,
02:34
feel good. Repeat.
02:35
Trigger, behavior, reward.
02:37
And each time we do this,
02:40
we learn to repeat the process
02:41
and it becomes a habit.
02:43
So later,
02:45
feeling stressed out triggers
that urge to smoke a cigarette
02:47
or to eat something sweet.
02:50
Now, with these same brain processes,
02:53
we've gone from learning to survive
02:55
to literally killing ourselves
with these habits.
02:57
Obesity and smoking
03:00
are among the leading preventable causes
of morbidity and mortality in the world.
03:02
So back to my breath.
03:07
What if instead of fighting our brains,
03:09
or trying to force ourselves
to pay attention,
03:11
we instead tapped into this natural,
reward-based learning process ...
03:14
but added a twist?
03:18
What if instead we just got really curious
03:20
about what was happening
in our momentary experience?
03:22
I'll give you an example.
03:24
In my lab,
03:26
we studied whether mindfulness training
could help people quit smoking.
03:27
Now, just like trying to force myself
to pay attention to my breath,
03:31
they could try to force
themselves to quit smoking.
03:34
And the majority of them
had tried this before and failed --
03:38
on average, six times.
03:41
Now, with mindfulness training,
03:43
we dropped the bit about forcing
and instead focused on being curious.
03:45
In fact, we even told them to smoke.
03:49
What? Yeah, we said, "Go ahead and smoke,
03:52
just be really curious
about what it's like when you do."
03:54
And what did they notice?
03:58
Well here's an example
from one of our smokers.
03:59
She said, "Mindful smoking:
04:02
smells like stinky cheese
04:04
and tastes like chemicals,
04:06
YUCK!"
04:07
Now, she knew, cognitively
that smoking was bad for her,
04:09
that's why she joined our program.
04:12
What she discovered just by being
curiously aware when she smoked
04:15
was that smoking tastes like shit.
04:20
(Laughter)
04:23
Now, she moved from knowledge to wisdom.
04:26
She moved from knowing in her head
that smoking was bad for her
04:30
to knowing it in her bones,
04:33
and the spell of smoking was broken.
04:35
She started to become
disenchanted with her behavior.
04:38
Now, the prefrontal cortex,
04:42
that youngest part of our brain
from an evolutionary perspective,
04:44
it understands on an intellectual level
that we shouldn't smoke.
04:48
And it tries it's hardest
to help us change our behavior,
04:52
to help us stop smoking,
04:56
to help us stop eating that second,
that third, that fourth cookie.
04:57
We call this cognitive control.
05:02
We're using cognition
to control our behavior.
05:04
Unfortunately,
05:07
this is also the first part of our brain
05:09
that goes offline
when we get stressed out,
05:10
which isn't that helpful.
05:13
Now, we can all relate to this
in our own experience.
05:14
We're much more likely to do things
like yell at our spouse or kids
05:16
when we're stressed out or tired,
05:19
even though we know
it's not going to be helpful.
05:21
We just can't help ourselves.
05:23
When the prefrontal cortex goes offline,
05:26
we fall back into our old habits,
05:29
which is why this disenchantment
is so important.
05:31
Seeing what we get from our habits
05:34
helps us understand them
at a deeper level --
05:35
to know it in our bones
05:38
so we don't have to force
ourselves to hold back
05:39
or restrain ourselves from behavior.
05:41
We're just less interested
in doing it in the first place.
05:43
And this is what mindfulness is all about:
05:46
Seeing really clearly what we get
when we get caught up in our behaviors,
05:48
becoming disenchanted on a visceral level
05:53
and from this disenchanted stance,
naturally letting go.
05:56
This isn't to say that, poof,
magically we quit smoking.
06:00
But over time, as we learn
to see more and more clearly
06:04
the results of our actions,
06:06
we let go of old habits and form new ones.
06:08
The paradox here
06:11
is that mindfulness is just
about being really interested
06:13
in getting close and personal
06:16
with what's actually happening
in our bodies and minds
06:17
from moment to moment.
06:20
This willingness
to turn toward our experience
06:21
rather than trying to make unpleasant
cravings go away as quickly as possible.
06:24
And this willingness
to turn toward our experience
06:28
is supported by curiosity,
06:31
which is naturally rewarding.
06:33
What does curiosity feel like?
06:34
It feels good.
06:36
And what happens when we get curious?
06:38
We start to notice that cravings
are simply made up of body sensations --
06:41
oh, there's tightness, there's tension,
06:44
there's restlessness --
06:46
and that these body
sensations come and go.
06:48
These are bite-size pieces of experiences
06:51
that we can manage from moment to moment
06:54
rather than getting clobbered
by this huge, scary craving
06:56
that we choke on.
07:00
In other words, when we get curious,
07:02
we step out of our old,
fear-based, reactive habit patterns,
07:04
and we step into being.
07:09
We become this inner scientist
07:11
where we're eagerly awaiting
that next data point.
07:14
Now, this might sound
too simplistic to affect behavior.
07:17
But in one study,
we found that mindfulness training
07:22
was twice as good as gold standard therapy
at helping people quit smoking.
07:25
So it actually works.
07:28
And when we studied
the brains of experienced meditators,
07:31
we found that parts of a neural network
of self-referential processing
07:34
called the default mode network
07:38
were at play.
07:39
Now, one current hypothesis
is that a region of this network,
07:41
called the posterior cingulate cortex,
07:44
is activated not necessarily
by craving itself
07:46
but when we get caught up in it,
when we get sucked in,
07:49
and it takes us for a ride.
07:51
In contrast, when we let go --
07:53
step out of the process
07:55
just by being curiously aware
of what's happening --
07:56
this same brain region quiets down.
07:59
Now we're testing app and online-based
mindfulness training programs
08:03
that target these core mechanisms
08:07
and, ironically, use the same technology
that's driving us to distraction
08:10
to help us step out
of our unhealthy habit patterns
08:14
of smoking, of stress eating
and other addictive behaviors.
08:17
Now, remember that bit
about context-dependent memory?
08:21
We can deliver these tools
to peoples' fingertips
08:24
in the contexts that matter most.
08:27
So we can help them
08:29
tap into their inherent capacity
to be curiously aware
08:30
right when that urge to smoke
or stress eat or whatever arises.
08:33
So if you don't smoke or stress eat,
08:38
maybe the next time you feel this urge
to check your email when you're bored,
08:40
or you're trying to distract
yourself from work,
08:43
or maybe to compulsively respond
to that text message when you're driving,
08:46
see if you can tap into
this natural capacity,
08:50
just be curiously aware
08:54
of what's happening in your body
and mind in that moment.
08:56
It will just be another chance
08:59
to perpetuate one of our endless
and exhaustive habit loops ...
09:00
or step out of it.
09:04
Instead of see text message,
compulsively text back,
09:05
feel a little bit better --
09:08
notice the urge,
09:10
get curious,
09:12
feel the joy of letting go
09:13
and repeat.
09:15
Thank you.
09:17
(Applause)
