#606: How to Activate Your Brain's Happy Chemicals
Episode Stats
Summary
Loretta Bruning is the author of several books on happiness in the human brain, including her latest, Tame Your Anxiety: Rewiring Your Brain for Happiness. In this episode, we discuss the similarities between human brains and the brains of other mammals, and how our brains release happiness-producing chemicals like dopamine, oxytocin, and serotonin to spur to seek rewards related to our survival needs. We also talk about the unhappy chemical of cortisol, which is released in response to perceived threats, and the factors that have increased our stress and anxiety in the modern world.

Brett McKay here, and welcome to another edition of the Art of Manliness podcast.

Everyone has experienced the way our feelings fluctuate day by day, even hour by hour.
00:00:15.540
Sometimes we're feeling up, sometimes we're feeling down.
00:00:17.980
My guest today says these oscillations are a result of nature's operating system, and
00:00:22.100
you can learn to better manage these emotional peaks and valleys.
00:00:25.620
She's the author of several books on happiness in the human brain, including her latest,

Tame Your Anxiety, Rewiring Your Brain for Happiness.
00:00:32.580
We begin our conversation by discussing the similarities between human brains and the brains
00:00:36.120
of other mammals, and how our brains release happiness-producing chemicals like dopamine,
00:00:40.400
oxytocin, and serotonin to spur to seek rewards related to our survival needs.
00:00:44.760
We also talk about the unhappy chemical of cortisol, which is released in response to perceived
00:00:48.680
threats, and the factors that have increased our stress and anxiety in the modern world.
00:00:52.800
Loretta then explains that the boost we get whenever the brain's happy chemicals are activated
00:00:56.620
doesn't last, and how we need to plan and execute healthy options for proactively stimulating
00:01:00.800
these chemicals, including creating expectations for rewards and finding small, positive ways
00:01:06.620
We end our conversation with how to manage spikes of cortisol in yourself, as well as help

00:01:28.260
All right, Loretta Rooney, welcome to the show.
00:01:35.400
What began your career in researching and writing about how the brain works in relation
00:01:42.880
Well, as always, it's short-run things and long-run things.
00:01:47.000
You could say that I grew up in a household with a lot of anxiety and unhappiness, and the
00:01:54.560
reason for it was not obvious, and in fact, it was sometimes blamed on me.
00:02:00.860
But I fortunately had some awareness that I could not possibly be causing all of this.
00:02:07.200
So, I think I always had some interest in, you know, what is it that drives the emotional
00:02:17.120
So, I spent most of my life in academia, but I was only peripherally involved in psychology.
00:02:26.520
And because I was only peripherally following psychology, I think it gave me the freedom
00:02:32.920
to sample different views rather than being forced to promote one particular paradigm in
00:02:40.800
And then when I became a parent and I saw the fact that children are not happy all the time as much as you
00:02:50.620
idealize what circumstances you think they will have, and that pushed me to look deeper for the truth.
00:02:59.340
And the one way, the way you approach, the way you explore anxiety and stress and even status amongst
00:03:07.780
humans is you have to understand that the brain shares characteristics with other mammals.
00:03:14.180
So, let's start there because I think it will guide the rest of our conversation.
00:03:17.440
How does our mammal brain contribute to either our well-being or whether we feel stressed out and anxious?
00:03:23.580
So, first on a simple level, beneath our cortex, we have the same brain as other animals.
00:03:31.100
So, people have heard of these limbic structures like the amygdala, the hippocampus, and all those
00:03:37.400
And it's really not important pointing to specific parts.
00:03:41.520
The point is that animals make complex decisions without any cortex at all.
00:03:47.300
And what that means is that when you tell yourself your reason for doing things,
00:03:53.060
that's just like a tiny percentage of what's going on.
00:03:57.040
So, much of what's going on is managed by chemicals.
00:04:02.360
They don't have any verbal inner dialogue, but positive chemicals motivate them to approach
00:04:12.520
And how do they know when to release the positive or negative?
00:04:16.620
It's with neural pathways created by whatever turned those chemicals on in their past.
00:04:22.720
So, that's, you could say, sort of a crapshoot in our lives.
00:04:27.400
It's just the random chance of early experience wires the lens through which we react to the
00:04:35.100
Well, let's talk about these basic needs that you say our mammal brain has and that these
00:04:40.920
different chemicals, neurotransmitters, they're there to help us to go for those needs.
00:04:50.200
So, animals try to survive by avoiding threat and seeking rewards.
00:04:58.000
So, the rewards are obviously food and warmth, whatever that specific animal needs.
00:05:05.300
But avoiding threats has to be pursued at the same time.
00:05:09.880
And we define threats and rewards with neural pathways built from past experience.
00:05:15.540
So, if you grow up in an environment where your needs are met and you're safe from threat,
00:05:23.860
then your brain sort of ranges out further and further looking for things that could threaten
00:05:36.660
So, that exploring, that need for exploration, which, you know, that could lead to a threat
00:05:43.200
or it could lead to reward, that's driven by dopamine, that neurotransmitter in our brain.
00:05:53.500
But every one of these happy chemicals has a downside.
00:05:56.880
And what you mentioned, you know, when you go out and seek rewards, but you could be disappointed,
00:06:01.980
you could be threatened, and the other part of the downside of dopamine, like all of them,
00:06:07.480
is you just get a short burst, and then it's metabolized.
00:06:11.920
So, it's like when you get what you want, the good feeling is gone, and then you have to get,
00:06:19.760
And the reason for that is that our ancestors had to keep filling their belly.
00:06:24.500
They didn't know where their next meal would come from.
00:06:26.840
So, dopamine motivates you to seek, seek, seek, because that's how you get the next meal.
00:06:34.300
Another one of those happy chemicals you talk about in the book is oxytocin, which sort of
00:06:39.860
fulfills the animal need for feeling like you're close to, I mean, it's like love.
00:06:44.820
It's what we did, the neurotransmitter that goes on in our brain when we hug or cuddle with
00:06:56.060
So, touch stimulates it, and sex stimulates it, but everyone knows that it's possible to
00:07:05.020
So, it helps to understand it from an animal perspective.
00:07:08.900
So, when you see two monkeys grooming, touch stimulates a little bit, and if you let another
00:07:17.800
animal close enough to you to touch your fur, they could kill you in an instant.
00:07:30.320
And sex is a lot of oxytocin at once, and then it's metabolized, and then it's gone.
00:07:36.560
But another way of looking at it is that when two monkeys groom together, they build their
00:07:42.640
oxytocin pathways so it's easier to trust the individuals who have groomed you in the past
00:07:52.660
And this is herd behavior also when we extend it to a group, that we trust them, and it's not
00:08:01.540
because of a sophisticated intellectual reason, but because if a predator comes, you're safer
00:08:14.880
Another happy neurotransmitter, happy chemical that we experience that also contributes to
00:08:22.660
So, this is complicated, but a century of research in zoology has taught us that mammals are very
00:08:32.060
hierarchical and competitive, and they actually are aware of each other's status.
00:08:38.760
And individuals promote their genes and get more reproductive opportunity when they raise
00:08:47.420
And more recent research in the late 20th century showed that your serotonin increases when you're
00:08:57.340
And like all the other chemicals, it's very ephemeral.
00:09:01.260
So, that means that if there's two of us and one banana, you know, serotonin gives you that
00:09:08.920
sense of confidence that motivates you to assert yourself and get the banana.
00:09:14.540
And in the animal world, animals never assert themselves unless they're sure they're going
00:09:19.280
to win, because if they get injured, they could easily die.
00:09:22.380
So, we look for that good feeling of serotonin, but we're not designed to have it all the time.
00:09:29.640
We're designed to save it for just the right situations.
00:09:34.280
So, we've talked about the happy chemicals that all mammals feel.
00:09:40.400
So, I focus on cortisol, which is, as many people have heard, called the stress chemical.
00:09:47.760
In the animal world, it's that emergency alarm system that tells you that there's an immediate
00:09:56.120
And it feels so bad that you can't focus on anything other than making it stop.
00:10:01.560
So, the simple example that we always hear about is if you're enjoying the delicious green
00:10:07.340
grass and then you smell a predator, cortisol motivates a gazelle to run from the predator,
00:10:16.540
But then, if you did nothing but run from predators all the time, then you'd starve to
00:10:21.260
So, the mammal brain evolved to weigh one threat against another.
00:10:26.000
So, at some point, you're so hungry that you run a little more risk to go out and do what
00:10:34.260
So, that's an example of, okay, a very obvious example that where animals are going to feel
00:10:41.740
But in your book, you talk about that sometimes being denied certain happy chemicals, right,
00:10:48.360
either oxytocin or serotonin, so you're denied social trust or status, that can also cause
00:10:54.180
cortisol to spike and for us to feel stressed out and anxious.
00:10:59.940
So, first, I would never say that we're denied it because that's like blaming the external
00:11:07.920
And to me, that is just a constant self-stressor that I think we're better off without.
00:11:14.980
So, I think we're better off to have the empowered feeling that I wanted a happy chemical
00:11:29.940
So, when you anticipate a reward and you don't get it, cortisol is released because that's
00:11:36.720
how the mammal brain protects you from wasting your effort on a failed pursuit.
00:11:42.000
So, you could think about a lion is making careful decisions about which gazelle to run after.
00:11:49.140
Otherwise, it would starve to death if it just ran after stuff.
00:11:53.440
So, disappointment is one big source of threatened feelings.
00:11:58.920
But another is like whenever our happy chemicals are on and then they're gone in a few minutes
00:12:05.560
and then you have to do something to stimulate them.
00:12:08.580
But if you don't understand this and if you don't have a sense of personal agency, then
00:12:15.500
you think that something is wrong with the world and why did I get deprived of happy chemicals
00:12:23.340
So, the important thing is that you know that you always have to do more to get more and if
00:12:31.160
one thing doesn't work that you can try something else.
00:12:34.020
But underneath that, we're aware of our own mortality.
00:12:43.500
So, the more you fail to activate your happy chemicals, the more aware you are of that underlying
00:12:54.620
Well, I think part of the problem with humans, so humans, unlike animals, yeah, we're aware
00:12:59.280
So, we've got to deal with that existential angst.
00:13:02.580
And also, the other problem with being human is we're oftentimes too smart for our own good.
00:13:08.440
So, that cortex part of our brain, our verbal part, we can take those disappointments that
00:13:14.180
we experience and use our cortex to make them worse than they actually are.
00:13:20.620
It's like, well, you know, I didn't get the job and because I didn't get the job, I'm going
00:13:25.140
Listen, because I'm homeless, like, we can do that with our brain.
00:13:27.960
Like, a rabbit wouldn't do that, but us humans can do that.
00:13:38.240
So, the human cortex can anticipate the future.
00:13:42.040
And that has actually protected us from a lot of harm.
00:13:46.520
And that's why we have higher survival rates than animals.
00:13:50.320
But because we're constantly anticipating harm, then we can give ourselves a lot of cortisol.
00:13:58.500
And if you think about our ancestors many thousands of years ago, they lived with a lot
00:14:05.680
So, because we've eliminated so many threats, we just look further and further for threats.
00:14:11.260
And that's why tiny social disappointments can feel like survival threats because we have
00:14:17.060
this huge threat detector and nothing else to focus it on.
00:14:23.580
I mean, this is something you've been reading about in the news that people, particularly
00:14:26.880
young people, are more, like, they're the most anxious generation.
00:14:34.800
I mean, this is just, I mean, you just mentioned that we kind of invent problems that aren't there.
00:14:44.880
So, one of them is because, as I said, when you're actually safe, it's not until you're
00:14:50.240
safe from hunger that you could worry about all this minutia.
00:14:54.080
And, like, my mother actually grew up with hunger.
00:14:56.580
So, it's really quite recent that humans are safe from hunger.
00:15:01.200
So, the next thing is that you pick up on your parent's sense of threat.
00:15:05.460
But, so, in the past, like, not too long ago, parents had 10 kids, and it was not unusual
00:15:14.700
You know, I don't know if you know the expression that kids are like pancakes.
00:15:18.800
You don't expect to, you know, you don't expect the first few to come out okay or something
00:15:25.980
So, today, people have fewer children, so they think everything must go perfectly, and children
00:15:35.460
Then, children pick up on their teacher's sense of threat and the media's sense of threat.
00:15:41.300
And, to an extent, they are intentionally trying to alarm us, both because of their political
00:15:48.760
persuasions and to get support, to recruit social support, because that's how mammals build
00:15:56.300
social solidarity, by focusing on common enemies.
00:16:00.520
And I imagine, for that status disappointment, social media doesn't help.
00:16:04.460
Yes, it's true, and yet everyone has focused on this, and the same patterns existed before
00:16:14.820
So, every generation uses whatever is the latest technology to explain their anxiety with their
00:16:24.980
So, when trains were first invented, people thought they were stressed because trains speeded
00:16:37.940
And then, when the telegraph made it possible for news to travel thousands of miles overnight,
00:16:45.660
they thought, oh, now we're so stressed because news is traveling so fast.
00:16:50.140
Yeah, so yeah, the more things change, the more they stay the same.
00:16:55.880
All right, so, okay, we've got an understanding of how our mammal brain works, how we have these
00:17:00.980
And if we don't have those needs, we have a disappointment, then cortisol is released,
00:17:05.620
and that can cause us to feel anxious and stressed out.
00:17:08.260
So, you offer sort of a solution, an idea, some tools you can use to manage that.
00:17:14.180
And the first part of this tool is asking, what does my mammal brain want?
00:17:19.060
So, how do you figure out what your mammal brain wants, whether you need social trust,
00:17:37.000
And when you have something going on, and you're expecting, oh, this is really going to be good,
00:17:48.440
It gives you the sense that your needs will be met.
00:17:51.280
The minute you don't have that, even if it's because you achieved your goal,
00:17:55.260
then you lose that good feeling of dopamine, that good sense of excitement,
00:18:01.280
So, that's why people look for excitement and look to the future and sometimes do harmful
00:18:09.980
Now, oxytocin is the sense of acceptance and belonging, and we all look for that.
00:18:17.140
But it's interesting that it's soon metabolized and it's gone.
00:18:21.780
So, the simple example is when you're with a group and you have a nice sense of solidarity
00:18:27.060
and safety, and then maybe after a while you're with this group and they get on your nerves
00:18:32.980
and you wish you could just go home and be alone.
00:18:36.220
But then when you're home and alone, then your inner mammal starts saying,
00:18:43.460
You know, of course, you don't think that works.
00:18:45.360
So, that's why, you know, we have ups and downs in all of these.
00:18:50.880
So, when you're in the one-up position for a moment, you get that nice feeling.
00:18:58.260
We could call it pride, confidence, ego, winner.
00:19:02.100
I have in my books like a list of 30 different synonyms because we think about it so much.
00:19:07.980
And yet, we're told that we shouldn't care about it.
00:19:10.180
And we learn to pretend that we don't care about it and say, oh, I don't care about that.
00:19:17.580
When we get it, it's gone in a few minutes because that's how it's designed to work.
00:19:25.820
So, we're all looking for all of them all the time.
00:19:31.220
So, some of them we feel like, oh, I'm good at that one.
00:19:36.180
And so, we tend to go for the one we're good at,
00:19:39.260
but we could possibly benefit more by going for the one that we're not as good at.
00:19:45.720
And when you're trying to figure this stuff out, how to scratch those itches,
00:19:49.120
as you said, with all these things, you could pick up, you can do things that are unhealthy.
00:19:53.360
So, like dopamine, you could pick up, take up gambling or drugs.
00:19:57.660
Oxytocin, you can get involved in relationships that aren't healthy.
00:20:00.420
Serotonin, there's lots of, I mean, YouTube's a perfect example.
00:20:03.940
You could do a lot of terrible things to get social status.
00:20:06.780
So, how do you ensure you pick things to scratch those needs that are healthy in the long run?
00:20:12.680
Yeah, I say that you could think of 10 examples in 10 seconds of bad ways to get happy chemicals.
00:20:21.760
So, what's so helpful is to understand that we're wired by past experience.
00:20:27.780
So, whatever triggered your dopamine when you were young is the way you expect to get it today.
00:20:34.060
Whatever triggered your serotonin when you were young is the way you expect to get it today.
00:20:38.520
So, we all, of course, get a little more sophisticated than the worst things we did when we were young,
00:20:45.120
but we sort of are playing in the same ballpark.
00:20:49.160
And, excuse me, it's hard to see this in yourself,
00:20:53.100
but when you talk to other people about it, it's sort of mind-blowing.
00:21:05.040
and you think, wow, it's mind-blowing how they're just repeating their childhood.
00:21:09.820
And I find myself doing it, and I see my husband doing it.
00:21:13.300
So, it takes a certain degree of self-acceptance to say, you know,
00:21:20.360
and that's why we can strive to add more leaves to our neural trees,
00:21:28.100
but we shouldn't hate the branches on our own trees,
00:21:35.740
We're going to take a quick break for your word from our sponsors.
00:21:55.940
It seems like it's like a, you're like constantly,
00:22:15.340
who try to direct your frustration into politics,
00:22:21.500
and you're taught to blame society for this treadmill feeling.
00:22:33.260
is get angry at society and join with other people
00:22:36.840
to fight society, and that's why they're telling you that,
00:22:39.840
because they want you to join with them and fight with them.
00:22:42.260
But you have like more options when you understand the mechanism,
00:22:47.560
but your options are limited to the realm of reality.
00:22:53.220
So what I suggest, I talk about it as if you are binging on junk food,
00:23:02.340
then you learn to stock your pantry with healthy food
00:23:09.600
So it's the same way, like if you feel that you're binging
00:23:17.840
that you plan in advance of healthy ways to stimulate them
00:23:27.980
so that in a bad moment, you know positive ways to stimulate it.
00:23:33.560
So instead of, like you'd say, if you're feeling that it's your board,
00:23:37.080
like have a list of things that you could go do
00:23:53.360
what in Alcoholics Anonymous they would call like the trigger.
00:23:56.620
It's the moment that sends you to that old harmful stimulator.
00:24:21.520
then you're like, how can I give myself the expectation of reward
00:24:26.300
in ways other than the way that comes most easily to mind?
00:24:33.920
is just a big neural pathway that's big because it was used a lot.
00:24:43.660
And I always explain that if you have a short-run goal,
00:24:53.580
And that's the healthy way to stimulate dopamine
00:24:56.300
because as your brain, you only need to get one step closer
00:24:59.940
for your brain to say, wow, it's coming, it's coming,
00:25:04.280
And if you have a few goals, then you can shift between them.
00:25:08.180
And so then you can always feel like you're getting ahead and making progress.
00:25:12.940
That's why planning for a vacation is often more fun than the actual vacation.
00:25:25.820
so many of our favorite dopamine stimulators are off limits,
00:25:31.240
including the very idea of planning for anything, period.
00:25:36.880
So you have to use your creativity and scale down.
00:25:47.660
Instead of just going to your weekend without any plans,
00:25:50.340
have just a short plan that you can look forward to.
00:26:01.740
And a lot of people are planning cooking projects
00:26:06.020
and learning a new skill that you've always wanted to learn.
00:26:10.420
And it's important to then break that big goal down into smaller steps
00:26:15.180
because otherwise it gets frustrating and you have to give up.
00:26:20.680
then you can constantly be enjoying that rewarding feeling.
00:26:28.720
is just having to plan whenever you're feeling down.
00:26:33.060
like just have a friend you could call and just talk to.
00:26:36.160
That could be something you could do to scratch that itch.
00:26:43.140
I have to admit that when I talk to other people
00:26:55.060
the fact is that we're very much wired by past experience
00:26:59.220
and we have specific ideas about how we want to get our oxytocin needs met.
00:27:08.800
and then make it a goal to expand those old patterns in a specific way.
00:27:15.920
So yeah, coming up with new strategies to get your oxytocin needs met
00:27:22.760
but you know people have had virtual book clubs,
00:27:26.860
I've even heard people having virtual cocktail hours.
00:27:29.620
So just look for ways to get social with a purpose beyond just grousing.
00:27:38.220
but I'm just not feeling like I'm not feeling good about myself.
00:27:41.680
I'm not feeling proud or like that successful feeling.
00:27:46.140
Again, sort of stocking your pantry with healthy things
00:27:54.860
So it's first, like I said with all the others,
00:28:02.640
So our brain evolved to constantly compare us to others.
00:28:16.860
and that motivates it to pull back and avoid getting bitten.
00:28:54.940
And you can't be in the one-up position every minute.
00:28:57.980
Even big celebrities are not in the one-up position
00:29:08.580
So finding small ways to enjoy status is useful.
00:29:14.780
And of course, people can do that in small, nasty ways.
00:29:31.580
how can I find a one-up feeling in healthy ways,
00:30:01.760
it has led to this sort of current share paradigm
00:30:42.900
And I know this is what social media is notorious for,
