where we discuss science and science-based tools 00:00:10.120 |
and I'm a professor of neurobiology and ophthalmology 00:00:17.440 |
Dopamine is a topic that I've covered before on this podcast, 00:00:22.800 |
Most people know that dopamine is involved in pleasure 00:00:27.080 |
And nowadays, people are starting to appreciate 00:00:35.560 |
Well, today, you're going to learn that indeed, 00:00:37.360 |
dopamine is responsible for all of those things, 00:00:40.180 |
but you are also going to learn that dopamine is critical 00:00:50.760 |
In fact, we are going to talk about the relationship 00:00:52.800 |
between dopamine and motivation and confidence 00:00:58.280 |
and we are going to cover tools that will allow you 00:01:02.340 |
to have a maximum motivation to overcome sticking points, 00:01:08.240 |
but also by understanding the neural circuits 00:01:10.940 |
in the brain and body that release and use dopamine, 00:01:14.900 |
by understanding what are called dopamine dynamics, 00:01:17.800 |
that is what gives rise to big peaks in dopamine 00:01:23.060 |
or what's referred to as our baseline level of dopamine, 00:01:25.900 |
which turns out to be our baseline levels of motivation 00:01:30.320 |
By understanding how those things relate to one another, 00:01:33.100 |
I assure you that by the end of today's episode, 00:01:42.420 |
how to ensure motivation on an ongoing basis, 00:01:49.620 |
as a way to do just that, to become more motivated. 00:01:54.900 |
although I will center around practical everyday examples 00:02:01.300 |
Today's discussion is really about pulling apart 00:02:03.660 |
these things that we call motivation, reward, 00:02:08.000 |
and understanding them in terms of their dopamine dynamics. 00:02:14.660 |
or whether or not today is your first exposure 00:02:18.280 |
today's episode is really designed to give you 00:02:22.380 |
so that you can leverage your dopamine circuitry 00:02:25.720 |
as well as tools to adjust dopamine circuitry and levels 00:02:32.860 |
Before we begin, I'd like to emphasize that this podcast 00:02:35.460 |
is separate from my teaching and research roles at Stanford. 00:02:40.160 |
to bring zero cost to consumer information about science 00:02:42.620 |
and science-related tools to the general public. 00:02:46.060 |
I'd like to thank the sponsors of today's podcast. 00:02:54.940 |
I've talked many times before on this and other podcasts 00:03:02.260 |
and have a good elevated mood throughout the day. 00:03:05.020 |
Sleep is just fundamental to our mental health, 00:03:10.860 |
A key thing we all need in order to get excellent sleep 00:03:15.420 |
Helix mattresses are designed for your unique sleep needs 00:03:23.000 |
and you take their very brief two or three-minute quiz, 00:03:26.960 |
do you sleep on your side, your back, or your stomach? 00:03:29.620 |
Do you tend to run hot or cold throughout the night? 00:03:41.420 |
I've been sleeping better than I ever have before. 00:03:43.740 |
So if you go to their site, you take the quiz 00:03:45.240 |
and you figure out what's the ideal mattress for you. 00:03:51.460 |
and they'll match you to a customized mattress, 00:03:53.300 |
and you'll get up to $350 off any mattress order 00:03:57.500 |

Today's episode is also brought to us by Whoop. 00:04:10.580 |
but also goes beyond that by providing real-time feedback 00:04:13.780 |
on how to adjust your physical training and sleep schedule 00:04:20.100 |
I've been working with Whoop on their Scientific Advisory 00:04:22.180 |
Council to help advance Whoop's technology and mission 00:04:29.100 |
As a Whoop user, I've experienced the health benefits 00:04:36.200 |
or a poor night's sleep by giving me a sleep score. 00:04:38.100 |
It tells me the percentage of rapid eye movement sleep 00:04:43.220 |
whether or not certain activities during my daytime, 00:04:48.900 |
how that's impacting my sleep and vice versa. 00:05:02.060 |
Today's episode is also brought to us by Roca. 00:05:06.420 |
that are uniquely tailored to the needs of athletes 00:05:10.020 |
The company was founded by two all-American swimmers 00:05:12.020 |
from Stanford, and everything about Roca eyeglasses 00:05:14.740 |
and sunglasses were designed with the biology, 00:05:23.520 |
has to contend with an enormous number of challenges 00:05:29.920 |
such that when you go from one environment to the next, 00:05:38.300 |
Another terrific thing about Roca eyeglasses and sunglasses 00:05:41.300 |
is that many of the performance glasses out there 00:05:43.980 |
that are designed for sport make people look like cyborgs, 00:05:46.280 |
which if you want that, they do have those options, 00:05:50.920 |
But they also have many options where the aesthetic 00:05:53.140 |
is more of the sort that you would wear to dinner 00:05:55.040 |
or to work or anywhere that you happen to be. 00:05:57.620 |
If you'd like to try Roca eyeglasses or sunglasses, 00:06:02.320 |
and enter the code Huberman to save 20% off your first order. 00:06:22.500 |
of those supplements is constantly expanding. 00:06:33.380 |
which simply refers to the fact that it's a chemical 00:06:36.080 |
that modulates or changes the electrical activity 00:06:48.000 |
and the neurons in your brain and spinal cord 00:06:50.880 |
and they connect to different areas of the body, 00:06:54.040 |
including basically every organ of your body. 00:06:56.440 |
And every organ of your body communicates back 00:07:05.680 |
that sense what sorts of nutrients you've eaten or drink, 00:07:09.120 |
and then send neural signals, electrical signals, 00:07:17.420 |
Dopamine as a neuromodulator has the basic property 00:07:26.340 |
like electrical potentials and things of that sort 00:07:34.320 |
in the biochemistry and biophysics of neurons 00:07:40.640 |
and we know that that neuromodulator can increase 00:07:47.060 |
where is dopamine released in the brain and body, 00:07:49.840 |
and what specific types of neurons is it impacting? 00:07:53.420 |
In other words, what specific types of functions 00:07:56.700 |
So there are basically five circuits within the brain 00:07:59.260 |
that use dopamine as the primary neuromodulator, 00:08:09.080 |
relatively quickly, giving you a little bit of nomenclature 00:08:12.200 |
and some sense of what each of those circuits looks like 00:08:16.680 |
The first circuit is the so-called nigrostriatal pathway. 00:08:23.940 |
so named because the neurons, they're actually very dark, 00:08:28.240 |
You'd be able to see this if I were to slice up a brain, 00:08:48.540 |
suppress action pathways, a topic for a future podcast. 00:09:07.600 |
to differentiate between them, I will do that. 00:09:10.120 |
Both of these pathways initiate from a set of neurons 00:09:13.160 |
in the so-called ventral tegmental area, or VTA. 00:09:35.180 |
Neurons in those areas project a bunch of different places, 00:09:40.440 |
those neurons are projecting to areas of the brain 00:09:43.400 |
which sits right above the roof of your mouth 00:09:45.020 |
and is responsible for a lot of basic functions, 00:09:48.040 |
things like maintaining your body temperature, 00:09:57.900 |
to the pituitary gland that caused the release of hormones 00:10:07.820 |
from the neurons in the VTA and nucleus accumbens 00:10:10.900 |
to the hypothalamus are basically using dopamine 00:10:13.560 |
to modulate the output of a lot of different things 00:10:21.680 |
but they're really basic functions for survival. 00:10:24.280 |
Now, the other pathway out of the VTA and nucleus accumbens 00:10:41.240 |
which is a structure that many of you have perhaps heard of, 00:10:43.840 |
but even if you haven't, it's important to know 00:10:45.560 |
this is an area that resides right behind your forehead 00:10:59.760 |
to making good or bad decisions, depending on context. 00:11:02.960 |
In fact, one of the primary functions of prefrontal cortex 00:11:07.360 |
whether or not, for instance, you are alone in your room 00:11:23.200 |
In fact, a guest on the Huberman Lab podcast, 00:11:25.500 |
and this is a guest whose episode hasn't aired yet, 00:11:28.000 |
described this beautifully, he's a neurosurgeon, 00:11:30.400 |
and he said, "The way to think about the prefrontal cortex 00:11:33.680 |
is it's basically an area of the brain that says shh, 00:11:41.680 |
And we know this because people that have damage 00:11:48.280 |
So the pathway from VTA and nucleus accumbens 00:11:51.680 |
to the prefrontal cortex is absolutely critical 00:11:54.880 |
because we are largely going to be discussing 00:12:05.440 |
whether or not we want to do something or not, 00:12:06.840 |
whether or not we feel we should or we shouldn't, 00:12:08.840 |
whether or not we feel we failed the last time 00:12:10.880 |
or there's a high probability of success the next time. 00:12:18.980 |
that is when thinking about this mesocortical pathway, 00:12:22.160 |
we really want to think about how dopamine is activating 00:12:25.440 |
or changing our propensity to do certain things 00:12:29.920 |
or prevent us from doing certain things and prevent action. 00:12:32.960 |
So basically you can think about the mesocortical pathway 00:12:35.760 |
as a circuit that really governs all of the major choices 00:12:39.920 |
about what to do and what not to do toward your goals 00:12:42.760 |
and away from the things that you want to avoid. 00:12:45.240 |
Now, the fourth dopamine pathway in the brain 00:12:50.840 |
And this is not one we're going to focus on too much today. 00:12:53.680 |
This is a pathway that relates to connections 00:12:57.620 |
Your pituitary gland being that gland that's, 00:13:01.480 |
is also receiving input from the hypothalamus 00:13:03.600 |
and is releasing a bunch of hormones into your bloodstream. 00:13:12.280 |
These are hormones that are impacting everything 00:13:18.200 |
It's governing things like cortisol release under stress, 00:13:32.320 |
So again, that's probably a topic for a future episode, 00:13:34.680 |
but it's important in reviewing the different brain circuits 00:13:44.740 |
And again, won't be the main topic of today's discussion, 00:13:53.680 |
That is the pie crust-like lining of neural tissue 00:13:58.200 |
Because remember, your eye is actually part of your brain 00:14:00.880 |
that got extruded from your brain during development. 00:14:03.020 |
You know, those two eyes that you see in the mirror 00:14:07.120 |
are actually two pieces of central nervous system. 00:14:20.640 |
so that you can see clearly both in the evening 00:14:23.120 |
and when it gets darker, you can still see a bit. 00:14:29.400 |
to your visual system in order to see clearly. 00:14:48.460 |
We are going to talk about the mesocortical pathway 00:14:58.620 |
and dopamine within the mesocortical circuit. 00:15:03.420 |
is that today's discussion is really about motivation, 00:15:10.940 |
that neither dopamine nor the mesocortical circuit 00:15:23.540 |
Now, of course, some people have a greater propensity 00:15:26.220 |
to pursue things like work or goals in athletics 00:15:32.580 |
Other people, unfortunately, have a greater propensity 00:15:41.900 |
to the extent that other types of pursuits in life 00:15:45.380 |
that are adaptive for us, like work, relationship, school, 00:15:49.740 |
In fact, the definition of addiction that I use 00:15:53.260 |
and that I believe really matches the neurobiology very well 00:16:01.320 |
Healthy functioning of the mesocortical pathway, however, 00:16:09.900 |
of all the sorts that I've mentioned earlier. 00:16:12.100 |
So if we can understand how that mesocortical pathway works 00:16:17.500 |
when dopamine is released and when it's not released, 00:16:34.660 |
dictates whether or not we are going to feel motivated 00:16:36.920 |
in the next five, 10, 15 minutes, hours, days, and weeks. 00:16:42.700 |
I promise I'll explain it to you in a simple way, 00:16:45.340 |
but I want you to get a circuit into your mind. 00:16:47.380 |
I want you to envision that there are these neurons, 00:16:49.100 |
little nerve cells in the VTA and nucleus accumbens. 00:16:54.020 |
They send their projections that we call axons, 00:16:57.240 |
and they can release dopamine into the prefrontal cortex. 00:17:10.140 |
that shh or quieting that we talked about earlier. 00:17:15.260 |
let's now take a look at how dopamine is released, 00:17:23.240 |
That is, dopamine is released into the frontal cortex, 00:17:29.460 |
And we can think of those as peaks in dopamine. 00:17:37.080 |
If I call it a peak, it's an increase and then a decrease. 00:17:56.180 |
So the two key things to understand about dopamine 00:18:03.380 |
certain compounds, drugs, or substances, food, et cetera, 00:18:10.560 |
Our dopamine baseline is our reservoir of dopamine. 00:18:18.100 |
And that dopamine pool is the pool of dopamine that we use 00:18:26.860 |
and sometimes they go to lower than baseline, 00:18:39.800 |
which is Dr. Kyle Gillette, who's an obesity specialist 00:18:45.880 |
including testosterone, estrogen in both men and women. 00:18:48.920 |
Want to check out his episodes on hormone health. 00:18:55.060 |
And he has this analogy for how dopamine works 00:19:00.060 |
And that analogy is this notion of a wave pool. 00:19:14.220 |
and we can think of those as little mini peaks, 00:19:23.840 |
and the frequency of those waves is very, very large, 00:19:29.940 |
which here I'm using as an analogy to dopamine, 00:19:32.740 |
can slosh out of the wave pool and the baseline drops. 00:19:42.360 |
well then the baseline, that is the water level in that pool, 00:19:49.640 |
for how dopamine works in the mesocortical pathway 00:19:57.480 |
how the peaks and the baseline relate to one another. 00:20:02.260 |
The peaks and the baseline are not independent 00:20:08.740 |
and just understand that if you get a great big huge wave, 00:20:17.400 |
But if you get big peak after big peak after big peak, 00:20:25.100 |
well then the baseline will stay relatively constant. 00:20:28.720 |
So let's think about dopamine peaks and baselines. 00:20:32.220 |
And let's remember that for every peak, there's a trough. 00:20:45.160 |
When we think about dopamine peaks and dopamine baselines, 00:20:49.180 |
we have to include that trough because that trough, 00:20:52.900 |
that is the level of dopamine below baseline, 00:20:57.680 |
really dictates whether or not you are going to feel 00:21:02.800 |
So I'm going to give you a visual in your mind. 00:21:04.520 |
The visual in your mind is an increase in dopamine 00:21:07.960 |
that's triggered by your desire for something. 00:21:11.400 |
And really it could be your desire for anything. 00:21:15.280 |
I really want a sandwich, I really want to think, 00:21:19.440 |
A really nice roast beef sandwich on sourdough 00:21:22.000 |
with a slice of Swiss tomatoes, slice of pickle. 00:21:24.760 |
Here I'm describing the sandwich that I would want. 00:21:26.800 |
So if you're hungry and you're thinking about that, 00:21:33.980 |
Dopamine is not just released when we get the reward, 00:21:39.040 |
Dopamine is released in anticipation of what we want. 00:21:43.640 |
That increase in dopamine is by no happenstance, no mistake, 00:21:51.020 |
relates also to our propensity and desire to move. 00:21:54.640 |
Remember earlier I told you there's a separate circuit 00:21:59.380 |
and that when it's depleted is causing things 00:22:02.520 |
like deficits and movement related to Parkinson's 00:22:16.620 |
So if I desire a sandwich or I desire a cup of coffee 00:22:24.020 |
that we could call a little mini peak in dopamine. 00:22:28.860 |
Very soon after I realize my desire for something, 00:22:40.120 |
below the level of dopamine that it was prior 00:22:43.320 |
to even thinking about the sandwich or the coffee 00:22:50.020 |
that triggers my desire to go out and find that sandwich, 00:22:57.180 |
Insert whatever it is that you happen to desire, 00:22:59.340 |
action or substance of any kind or person, et cetera. 00:23:15.140 |
Then very quickly it comes down below baseline 00:23:20.220 |
I'm looking for where I can get that sandwich. 00:23:25.460 |
Now is the stage in which I have to think about 00:23:31.340 |
that is the things in my environment that signal 00:23:33.340 |
whether or not I'm likely to get that sandwich or not. 00:23:36.260 |
And so, for instance, if I were to go to my phone 00:23:38.340 |
and order food on a nap or walk down the street 00:23:43.380 |
that's a cue that I'm likely to relieve that drop 00:23:48.780 |
in dopamine and get not just back to baseline, 00:23:57.780 |
they're open, they're making the sandwich that I want, 00:23:59.700 |
they make my sandwich and great, I get that sandwich. 00:24:06.460 |
Some degree of my liking it or not liking it. 00:24:12.160 |
but all I'm doing is comparing my desire for that sandwich 00:24:18.440 |
And chances are it's going to relieve that craving, 00:24:23.940 |
that had fallen below baseline, up, up, back to baseline. 00:24:43.900 |
However, chances are the sandwich is more or less 00:24:51.300 |
Well, there's a concept called reward prediction error. 00:24:53.760 |
Reward prediction error says that the dopamine 00:24:59.280 |
that's released from the VTA and nucleus accumbens, 00:25:13.000 |
minus what you expected, that's reward prediction error. 00:25:16.320 |
So if the sandwich is basically what I expected to get, fine. 00:25:19.520 |
Dopamine comes down basically to a baseline level 00:25:25.400 |
before I ever thought about the sandwich at all. 00:25:30.320 |
and is completely amazing, just an amazing sandwich, 00:25:33.640 |
well then the level of dopamine that I experienced 00:25:36.400 |
when I consumed that sandwich is going to be even greater 00:25:39.520 |
and it's going to be that minus what I expected. 00:25:43.060 |
So there it's a bigger reward prediction error 00:25:45.840 |
in the direction of higher peak by consuming the sandwich. 00:25:50.480 |
And then of course, there's the other possibility, 00:25:54.720 |
or the sandwich they make me is lousy or doesn't taste good 00:25:57.960 |
or something happened in the consuming of that sandwich 00:26:03.240 |
In which case, if we take that reward experienced 00:26:05.960 |
minus reward predicted from the initial craving, 00:26:10.880 |
well then it's going to be less than what I expected 00:26:16.260 |
where it was prior to even desiring the sandwich. 00:26:20.000 |
Okay, so all of this might seem a little bit complicated 00:26:26.080 |
but then our level of dopamine drops below baseline 00:26:42.200 |
you're not conscious of your dopamine levels, 00:26:44.200 |
you experience this as context dependent craving and pursuit 00:26:49.880 |
is involved in context setting and craving and pursuit 00:26:55.960 |
which is one of the general features of the dopamine system. 00:27:02.680 |
and you can also see how it's a perfect system 00:27:05.480 |
for desire and pursuit of anything, not just sandwiches 00:27:11.960 |
but everyday and therefore applicable example. 00:27:14.680 |
So just by understanding reward prediction error 00:27:23.780 |
but then drops your level of dopamine below baseline 00:27:29.040 |
you are already halfway through the conceptual aspect 00:27:32.160 |
of today's podcast because if you can understand that, 00:27:40.960 |
it puts you into motion but then pretty quickly, 00:27:45.240 |
you're starting to feel the pain of not having that 00:27:52.520 |
This is a subtle effect but if you watch for it, 00:27:55.100 |
you'll start to see it or experience it within yourself. 00:28:13.640 |
to leverage all sorts of aspects of the dopamine system 00:28:20.600 |
or when you have the propensity to procrastinate 00:28:27.600 |
and acknowledge one of our sponsors, Athletic Greens. 00:28:35.460 |
that covers all of your foundational nutritional needs. 00:28:41.040 |
so I'm delighted that they're sponsoring the podcast. 00:28:48.920 |
is that it gets me the probiotics that I need for gut health. 00:28:56.160 |
that communicate with the brain, the immune system 00:28:57.920 |
and basically all the biological systems of our body 00:29:00.320 |
to strongly impact our immediate and long-term health. 00:29:03.960 |
And those probiotics in Athletic Greens are optimal 00:29:09.660 |
In addition, Athletic Greens contains a number of adaptogens, 00:29:13.640 |
that all of my foundational nutritional needs are met 00:29:25.280 |
that make it really easy to mix up Athletic Greens 00:29:27.600 |
while you're on the road, in the car, on the plane, et cetera 00:29:30.180 |
and they'll give you a year's supply of vitamin D3K2. 00:29:40.580 |
Now I'd like to talk about the dynamics of dopamine release 00:29:50.400 |
either this one or as a guest on other podcasts, 00:29:57.860 |
Isn't it just enough to know that there are peaks and troughs 00:30:02.080 |
Well, it turns out that if you can understand 00:30:12.000 |
you'll be in an amazing position to overcome procrastination 00:30:16.280 |
and essentially pursue any goals in an ongoing basis. 00:30:19.980 |
So I'm very excited to share this information with you 00:30:21.960 |
because I do think that it has tremendous actionable power. 00:30:27.920 |
to a number of different findings that have been made, 00:30:35.560 |
And it has to do with the fact that the peak and trough 00:30:38.720 |
and baseline that I talked about a moment ago 00:30:52.320 |
But if we were to zoom in on that peak and the reward, 00:30:55.960 |
in other words, really zoom in on the whole process 00:31:00.880 |
that is the neurons and VTA and nucleus accumbens 00:31:07.040 |
what we discover is nothing short of amazing. 00:31:10.560 |
What we discover is that whenever we're pursuing something, 00:31:16.440 |
as to whether or not we are on the right path 00:31:26.360 |
as to whether or not we are confident or pessimistic 00:31:29.120 |
as to whether or not we're going to achieve that thing. 00:31:30.760 |
Now, this is vitally important for anyone out there 00:31:33.340 |
who finds it hard to get motivated and stay motivated. 00:31:43.200 |
and wonders why is it that some people are just so motivated 00:31:46.760 |
and other people have such trouble with motivation? 00:31:49.520 |
Why is it that some people require perfect conditions 00:32:01.360 |
are very good at achieving our goals in one context 00:32:08.240 |
I'll stay with the example of the roast beef sandwich 00:32:15.820 |
The cue that we're going to likely get what we want. 00:32:23.000 |
So for instance, the sign that there's a deli on the corner 00:32:26.680 |
or that I opened my phone and that there's an app 00:32:32.040 |
that sells the particular sandwich that I like. 00:32:34.160 |
That cue, as I mentioned before, increases dopamine. 00:32:43.620 |
Then as I mentioned, dopamine drops below baseline. 00:32:53.960 |
either with my thumbs on my phone through the app 00:33:02.400 |
there is a peak in dopamine of varying height, 00:33:06.720 |
depending on how satisfying I find the reward to be 00:33:09.840 |
when I actually get that sandwich, get that goal. 00:33:14.660 |
Now keep in mind, there is some time delay between the cue, 00:33:18.460 |
the app, the deli, et cetera, and when I get my sandwich. 00:33:24.880 |
That gap is going to be different for different things. 00:33:29.280 |
it's going to be four years if the diploma is your goal. 00:33:44.320 |
in this textbook, on this dating app, or at that deli. 00:33:53.220 |
and involve everything from how long the line is at the deli 00:33:56.440 |
to whether or not you're seeing the types of people 00:34:02.760 |
whether or not someone's texting you back or not. 00:34:08.340 |
and adjusting your baseline level of dopamine all the time 00:34:16.420 |
is it doesn't just compare the height of the peak 00:34:39.940 |
In other words, the dopamine system is very good 00:34:43.880 |
at subconsciously parsing what are the things that happen 00:34:50.120 |
And that's part of the learning that dopamine achieves. 00:35:28.620 |
of whatever it is that we're trying to pursue. 00:35:33.980 |
or perhaps even an overwhelming amount of detail, 00:35:41.520 |
what happened prior to getting or not getting a reward. 00:35:53.640 |
that takes you through that entire round of pursuit. 00:35:59.720 |
there's the stimulus, the desire, the I want that. 00:36:02.820 |
That's the first thing that leads to that peak. 00:36:13.720 |
but from a separate set of neurons within this circuit 00:36:18.320 |
And the entire time that it's driving you forward, 00:36:21.120 |
it's paying attention to what's there along the way, 00:36:28.600 |
So those three components, the learning contingency, 00:36:32.360 |
which has to do with the stimulus and the reward 00:36:50.060 |
or after you do anything that you desire to do, 00:36:56.080 |
and nucleus accumbens and goes up to your cortex, 00:37:30.280 |
which will allow you to overcome procrastination points, 00:37:35.600 |
and indeed to reset your motivation in an ongoing way 00:37:40.600 |
Okay, so let's take everything that I just told you 00:37:44.360 |
It's still important, but let's just set it aside. 00:37:46.080 |
You don't have to think about any of those details 00:37:51.640 |
because in biology and in psychology, frankly, 00:37:55.900 |
it really often pays to think about the extremes first 00:37:59.300 |
and then work our way towards more typical circumstances. 00:38:03.220 |
addiction unfortunately is very common nowadays. 00:38:11.800 |
in alcohol use disorder among women in the last 30 years. 00:38:15.480 |
I talked a little bit about this in the episode 00:38:21.040 |
I'm not somebody that is completely against alcohol 00:38:26.320 |
Turns out two drinks a week, probably fine health-wise. 00:38:31.240 |
If we're honest, zero is better than any alcohol. 00:38:36.300 |
Past two drinks, you start running into problems. 00:38:38.700 |
And yet many, many people out there, male and female alike, 00:38:42.200 |
suffer from alcohol use disorder, also called alcoholism. 00:38:47.900 |
The same is also true for things like methamphetamine 00:38:51.040 |
or cocaine or other types of substance addictions. 00:38:55.140 |
And the same is also true for a lot of behavioral 00:38:58.420 |
or what are sometimes called process addictions, 00:39:00.620 |
things like sex addiction or video game addiction 00:39:25.500 |
pick your substance or behavior that you see out there 00:39:35.440 |
Well, addiction involves dopamine among other things often, 00:39:41.500 |
But if we were to think about what's the stimulus 00:39:44.540 |
in an addiction and what's the peak in dopamine, 00:39:51.540 |
it all becomes very clear as to why addiction happens 00:39:59.260 |
Cocaine causes dramatic increases in dopamine 00:40:04.460 |
So if somebody craves cocaine, what are they craving? 00:40:10.020 |
They're craving the increased level of alertness. 00:40:13.400 |
They're craving a number of things associated 00:40:16.160 |
with the feeling of being under the influence of the drug. 00:40:19.780 |
But the stimulus for it simply becomes that line of cocaine 00:40:31.200 |
What happens is they snort, smoke, or inject cocaine, 00:40:36.200 |
and dopamine levels almost immediately go up, up, up, up, 00:40:42.460 |
So the time gap between the stimulus and the dopamine 00:40:49.940 |
that there's really no other contingencies in between 00:40:56.720 |
In fact, what does the system, quote unquote, learn? 00:40:59.860 |
It learns cocaine equals massive amounts of dopamine 00:41:04.840 |
equals feeling euphoric and energetic, et cetera. 00:41:08.100 |
And in doing that, it reinforces the whole circuit 00:41:12.600 |
so that that short, we can even say hyper short contingency, 00:41:20.300 |
So much so that longer contingencies of, say, 00:41:27.340 |
generating a fitness program or a professional program 00:41:32.820 |
which takes not just many days, but many weeks and years, 00:41:36.380 |
well, none of that is going to lead to peaks in dopamine 00:41:45.460 |
It is both the duration between desire and effect. 00:41:50.460 |
And when I say effect, I mean the rewarding properties 00:41:54.680 |
That's important, so very short gaps teach the system 00:42:01.640 |
Makes it very hard to pursue things that take longer. 00:42:05.020 |
So when we say it's the short, or in this case, 00:42:08.180 |
hyper short distance or time between the stimulus 00:42:12.440 |
and the dopamine, what we're really talking about, 00:42:25.940 |
And in addition to that, and this is very important, 00:42:36.180 |
the further below baseline the dopamine drops 00:42:43.260 |
it's a very fast and very large rise in dopamine 00:42:46.840 |
followed by a steep drop and very deep trough 00:43:03.140 |
If you recall what we talked about a little bit earlier, 00:43:15.380 |
where people start pursuing peaks in dopamine 00:43:27.540 |
and to remember if you want to avoid this whole thing. 00:43:31.840 |
Don't do cocaine, don't try it, don't use it. 00:43:36.020 |
Those are all sort of one in the same, frankly. 00:43:44.340 |
that don't at some point run into either a financial, 00:43:46.880 |
psychological, physical, or some other problem. 00:43:50.600 |
The other thing that's absolutely critical to keep in mind, 00:43:57.680 |
and on this podcast, excellent book, by the way, 00:44:06.160 |
not just drug addiction, but other types of addiction. 00:44:08.880 |
Again, the name of that book is "Dopamine Nation." 00:44:10.560 |
We'll provide a link to it in the show note captions. 00:44:33.800 |
And worse still is that the peaks in dopamine 00:44:38.040 |
that are created from more consumption of cocaine 00:44:48.540 |
So the whole system is shifting away from pleasure 00:44:50.920 |
and more to pain and the desire for pursuit of the drug. 00:45:10.120 |
and the rates at which those peaks take place, 00:45:12.700 |
'cause remember, the time to peak is just as important 00:45:26.420 |
positron emission tomography, combined with blood draws 00:45:35.300 |
just kind of on a background of no drug taking of any kind, 00:45:39.820 |
the neurons in the ventral tegmental nucleus accumbens area 00:45:43.560 |
are firing at a rate of about three to four per second, 00:45:48.680 |
of dopamine release, your forebrain is always seeing 00:45:56.440 |
and you're relatively hungry, that would double, okay? 00:45:59.920 |
So this probably happened when you decide to eat lunch today 00:46:06.480 |
and then depending on how much you enjoyed that food, 00:46:09.500 |
it might triple or quadruple, it might be lower 00:46:12.800 |
than it was during the anticipations we talked about before. 00:46:16.660 |
So there's an approximate doubling under conditions 00:46:26.920 |
For people that use nicotine, either smoking, vaping, 00:46:31.860 |
snuffing, or dipping, all routes of nicotine administration 00:46:36.860 |
that I covered in our episode about nicotine, 00:46:46.640 |
Cocaine is going to increase the rate of dopamine output 00:46:50.400 |
into the prefrontal cortex by about 1,000%, okay? 00:46:56.340 |
is a 10-fold increase in the amount of dopamine 00:47:02.160 |
as measured by the rates of firing of these dopamine neurons. 00:47:05.440 |
Methamphetamine is going to be anywhere from 1,000%, 00:47:11.440 |
It really varies depending on the potency of the drug 00:47:15.580 |
And here's where perhaps it gets a little more interesting. 00:47:17.720 |
Some of you are probably wondering about caffeine 00:47:22.960 |
Now, there are the numbers vary tremendously, 00:47:27.240 |
that across the board, not just for caffeine, sex, 00:47:35.700 |
and other substances and what we call motivated behaviors, 00:47:43.600 |
provided it's age-appropriate, context-appropriate, 00:47:52.260 |
If it's not, well, then consider it maladaptive. 00:47:55.060 |
Some people will sit down to play a video game. 00:48:05.400 |
in the rate of dopamine output from their nucleus accumbens. 00:48:08.300 |
For other people, it's going to be a 10-fold increase. 00:48:13.000 |
I don't have anything against them, I don't dislike them, 00:48:25.620 |
So the typical range that's cited in the literature 00:48:28.580 |
is anywhere from a four to five-fold increase 00:48:37.460 |
Caffeine is a little bit of a special circumstance 00:48:43.980 |
but increasing the amount of dopamine receptors over time. 00:48:47.340 |
And there aren't a lot of excellent measurements 00:48:59.980 |
based on the overall picture of the literature, 00:49:07.340 |
of the VTA nucleus accumbens to prefrontal cortex 00:49:10.840 |
when we anticipate and when we drink our coffee. 00:49:18.580 |
these are relative levels and they are distribution. 00:49:27.560 |
So some people are going to achieve more dopamine release 00:49:30.820 |
or less dopamine release from one behavior or substance. 00:49:33.680 |
However, it's very clear that cocaine, methamphetamine, 00:49:39.660 |
are way out on the right-hand side of the curve, 00:49:42.660 |
causing enormous increases in dopamine very quickly. 00:49:46.200 |
And the other things that we described have, again, 00:49:59.900 |
is the single molecule that's causing the craving 00:50:08.740 |
And the learning of all of that craving, pursuit, 00:50:12.380 |
and actual experience is what predicts whether or not 00:50:14.900 |
we will re-engage, reuse that substance or not, 00:50:24.260 |
But if you understand how the height of those peaks 00:50:27.060 |
in dopamine and the rate to reach those peaks 00:50:30.300 |
and the troughs that result and how long the troughs take 00:50:33.900 |
if you understand or a little or all of that, 00:50:36.660 |
you're really in a terrific position to understand 00:50:40.480 |
for the pursuit of healthy goals and behaviors. 00:50:43.660 |
I should mention one thing about recovery from addiction, 00:50:46.220 |
which is that the reset of all that dopamine circuitry 00:50:51.560 |
depending on the addiction, 30 days of complete abstinence. 00:50:55.160 |
That 30 days of complete abstinence inevitably involves 00:51:00.540 |
anxiety, insomnia, et cetera, that relates to the big trough 00:51:18.320 |
Somebody really needs to work with an addiction specialist, 00:51:20.620 |
and sometimes there needs to be a tapering off 00:51:23.360 |
For other addictions, it can be quote unquote cold turkey. 00:51:26.400 |
And then of course, there are other addictions, 00:51:32.800 |
for which the desired outcome is not necessarily 00:51:38.100 |
but to set some constraints around the behavior 00:52:11.060 |
in those particular behaviors in certain places 00:52:14.340 |
and certain times when it's context appropriate. 00:52:16.760 |
There are numerous examples of binding behaviors 00:52:23.680 |
when the engagement with the dopamine releasing behavior 00:52:28.440 |
So what's happening when people decide to go cold turkey 00:52:33.140 |
Well, what's happening is that people are engaging 00:52:35.860 |
the specific circuitry within the prefrontal cortex 00:52:39.480 |
that, as I mentioned at the beginning of the episode, 00:52:45.640 |
the prefrontal cortex is essentially getting trained up 00:52:48.680 |
to understand that, okay, certain things like food 00:52:58.640 |
in appropriate amounts or in particular contexts. 00:53:02.940 |
That requires the context setting goal-directed behavior 00:53:12.040 |
and actually this is not an episode about addiction. 00:53:44.160 |
not just get good at achieving one kind of goal, 00:53:46.440 |
but really understand and get really, really good 00:53:49.200 |
at setting goals and pursuing goals of different kinds 00:53:52.760 |
that are adaptive in different areas of life, 00:53:55.200 |
because we all are going to have to pursue goals 00:53:57.000 |
in school, work, relationships, fitness, mental health, 00:54:01.820 |
and on and on in order to be our best selves, that's clear. 00:54:05.980 |
Well, all of that is possible using the same basic set 00:54:09.480 |
of dopamine circuits and the same basic dynamics of dopamine. 00:54:14.060 |
So for instance, if we are going to feel motivated at all, 00:54:17.740 |
that is, if we are going to wake up in the morning 00:54:21.920 |
in which we feel like we are capable of pursuing goals, 00:54:30.200 |
In other words, we are going to have to have enough dopamine 00:54:32.700 |
in the wave pool, enough water in the wave pool, that is, 00:54:36.960 |
before we can generate any waves or peaks in dopamine, 00:54:42.000 |
So how do we achieve a healthy baseline level of dopamine? 00:54:52.240 |
and that to some of you might seem a little mundane, 00:54:54.500 |
although some of them are a bit more sophisticated, 00:54:58.120 |
The good news is that we can all control these things, 00:55:03.160 |
but they do require some degree of regular upkeep and effort. 00:55:06.920 |
Those things include what I call the very basics. 00:55:18.240 |
Those are going to be getting sufficient amounts 00:55:22.380 |
something that we've done several episodes on 00:55:25.960 |
So you can see the Master Your Sleep episode, 00:55:31.440 |
and just get right to the tools, we have a sleep toolkit, 00:55:34.800 |
or it's actually called the Toolkit for Sleep, 00:55:49.120 |
and for you to have a level of baseline dopamine 00:55:51.740 |
that will allow you to even consider your goals 00:55:57.120 |
Second, there are practices that are supported 00:56:04.180 |
that are independent of sleep, but are similar to sleep, 00:56:07.080 |
and I like to refer to these as a non-sleep deep rest. 00:56:16.080 |
of sitting eyes closed, focusing on your third eye center, 00:56:26.720 |
in the context of today's discussion, but I'll repeat. 00:56:35.200 |
However, non-sleep deep rest, so-called NSDR, 00:56:41.600 |
which is where you lie there, you do a sort of body scan, 00:56:44.280 |
some long exhale breathing, NSDR is very similar. 00:56:47.560 |
You can find a link to a zero-cost NSDR on YouTube. 00:56:53.360 |
There are also 20 and 30-minute ones out there, 00:56:58.280 |
Those have been shown to increase the amount of dopamine 00:57:08.160 |
So quality sleep, non-sleep deep rest, aka yoga nidra, 00:57:12.000 |
very powerful ways to keep your baseline level of dopamine 00:57:17.360 |
In addition to that, nutrition no doubt plays a role 00:57:24.600 |
is the rate-limiting enzyme for the synthesis of dopamine. 00:57:28.280 |
Tyrosine is present in varying levels in different foods. 00:57:39.840 |
like Parmesan cheese has high levels of tyrosine, 00:57:43.000 |
certain meats, certain nuts, certain vegetables. 00:57:47.000 |
you can find those there, but you need proper nutrition 00:57:49.380 |
and therefore nutrients, in particular tyrosine, 00:57:53.040 |
in order to have sufficient levels of baseline dopamine. 00:57:58.420 |
these are things that we come back to almost every episode, 00:58:00.440 |
but I don't think they can be repeated enough, 00:58:05.820 |
You might be able to skip a day here or there 00:58:10.520 |
but really every 24 hours, we need to re-up our sleep. 00:58:17.180 |
Even if you're fasting, you're re-upping your nutrients 00:58:27.360 |
Check out the episode on lighting your health 00:58:39.520 |
minimum 20 or 30 minutes on a very overcast day, 00:58:50.040 |
but yes, you want to face eastward towards the sun, 00:58:59.320 |
which is excellent because you want cortisol elevated 00:59:02.960 |
early in the day and you want it lower later in the day, 00:59:06.860 |
between the cells in your eye that sense sunlight, 00:59:14.160 |
and the relationship between the hypothalamus 00:59:16.240 |
and the pituitary and other endocrine organs, 00:59:26.540 |
and hormones that lead to states of wellbeing, 00:59:29.880 |
elevated mood, alertness, et cetera, throughout the day. 00:59:37.480 |
does increase your levels of dopamine, not just cortisol. 00:59:41.520 |
And fourth on the list is going to be movement, 00:59:50.960 |
Here, we're not talking about achieving peaks in dopamine. 01:00:06.620 |
of if not every day, at least five days a week, 01:00:09.700 |
a mixture of cardiovascular and resistance exercise. 01:00:16.160 |
and maintain an elevated level of baseline dopamine. 01:00:24.060 |
It's also about the baseline level of dopamine 01:00:34.400 |
The circuits in the brain and body that generate movement, 01:00:40.380 |
as I mentioned earlier, that nigrostriatal pathway. 01:00:46.520 |
from the VTA nucleus accumbens to cortical circuit, 01:00:50.860 |
that we've mainly been focusing on today, but they interact. 01:00:56.180 |
you ensure that you're maintaining elevated levels 01:01:02.620 |
in any kind of motivated pursuit behavior of any kind. 01:01:05.880 |
So those are the fundamentals that will set the level 01:01:14.100 |
Yes, there is variation based on both genetics 01:01:18.020 |
and circumstance in baseline levels of dopamine. 01:01:20.340 |
Someone's going through a particularly hard time, 01:01:26.260 |
that simply affords them higher levels of baseline dopamine. 01:01:48.580 |
Some people just seem to have lower activation energy 01:01:54.800 |
Some of us have lower levels of baseline dopamine. 01:02:13.060 |
InsideTracker is a personalized nutrition platform 01:02:21.740 |
I've long been a believer in getting regular blood work done 01:02:24.020 |
for the simple reason that blood work is the only way 01:02:27.000 |
that you can monitor the markers, such as hormone markers, 01:02:31.460 |
that impact your immediate and long-term health. 01:02:34.200 |
One major challenge with blood work, however, 01:02:36.320 |
is that most of the time it does not come back 01:02:49.700 |
because it has a personalized dashboard that you can use 01:02:52.640 |
to address the nutrition-based, behavior-based, 01:02:58.420 |
in order to move those values into the ranges 01:03:00.560 |
that are optimal for you, your vitality, and your longevity. 01:03:08.960 |
ApoB is a key marker of cardiovascular health, 01:03:21.840 |
Again, that's insidetracker.com/huberman to get 20% off. 01:03:30.520 |
and some of those get us into the realm of supplements 01:03:37.140 |
that are purely behavioral in nature, are zero cost, 01:03:40.200 |
and that have been shown in the research literature 01:03:54.360 |
what's the difference between a baseline and a peak, really? 01:03:58.340 |
Because if, for instance, you get a big peak, 01:04:04.280 |
so how do you distinguish between peak and baseline? 01:04:15.760 |
And more importantly, how do you raise your set point? 01:04:18.080 |
Ah, well, if you're not already asking that question, 01:04:21.760 |
I define an increase in your baseline level in dopamine 01:04:29.160 |
When we think about cocaine, amphetamine, pornography, 01:04:44.120 |
on the order of minutes to an hour, sometimes longer. 01:04:49.920 |
I said that's how long those increases in dopamine 01:04:53.380 |
even if you were to continually engage in those behaviors. 01:05:08.980 |
There are tools and techniques that you can use 01:05:18.300 |
to the basic tools that I mentioned a few moments ago. 01:05:21.080 |
The simplest one for which there are excellent data, 01:05:28.880 |
is that exposure of your body up to the neck to cold water, 01:05:33.880 |
and it doesn't have to be super cold, by the way, 01:05:37.480 |
to cold water has been shown to increase baseline levels 01:05:40.480 |
of dopamine and the other so-called catecholamines, 01:05:43.120 |
which include norepinephrine and epinephrine, 01:05:45.160 |
but for sake of today's discussion, dopamine in particular, 01:05:55.360 |
There've been some additional scientific studies 01:06:01.440 |
You can accomplish this a number of different ways. 01:06:03.480 |
You could get into a cold shower in the morning, 01:06:05.640 |
and I do recommend doing this in the morning, 01:06:06.960 |
and in that case, it's okay to get the water on your head. 01:06:14.960 |
In these circumstances, I'm not suggesting this 01:06:16.960 |
for sake of increasing metabolism or fat loss. 01:06:19.840 |
You know, the whole discussion around deliberate cold 01:06:26.600 |
mostly because we're focused on the clear ability 01:06:29.760 |
of deliberate cold exposure to increase dopamine 01:06:32.340 |
for long periods of time, aka your dopamine baseline. 01:06:35.620 |
The ways to do this vary depending on the temperature. 01:06:38.420 |
So for instance, there are data pointing to the fact 01:06:41.400 |
that if you want to get a long lasting increase 01:06:45.280 |
you could take a very cold shower or cold plunge or ice bath 01:06:54.120 |
maybe three minutes, but probably 30 seconds to two minutes. 01:07:01.320 |
that's going to cause anyone to have a heart attack 01:07:13.540 |
for the short exposure, long dopamine release approach, 01:07:20.080 |
that you start warmer than you think you need to, 01:07:25.080 |
But we're really talking about ranges in temperature 01:07:27.660 |
from anywhere from about 37 degrees Fahrenheit 01:07:32.880 |
Again, be careful, approach it with caution and ease into it. 01:07:42.160 |
or hypertrophy training because within the six hours 01:07:48.800 |
can suppress the strength and hypertrophy adaptation 01:07:52.000 |
that the training is designed to accomplish, okay? 01:07:55.680 |
The other approach that's supported by the literature 01:08:03.280 |
is to get into warmer water, so not warm, but warmer, 01:08:06.880 |
so 60 degree Fahrenheit water up to the neck, 01:08:10.960 |
and to stay there for about 45 to 60 minutes. 01:08:14.460 |
The reason I don't think most people will do that, 01:08:21.120 |
is that most people don't have 45 to 60 minutes each morning 01:08:25.400 |
And in that study, they actually had them sitting 01:08:26.920 |
in lawn chairs, basically, in the shallow end of a pool 01:08:31.880 |
and then measuring dopamine release and so forth. 01:08:34.160 |
So there are a bunch of different ways to do this. 01:08:45.120 |
meaning that you feel agitated and you want to get out, 01:08:47.560 |
but that you're confident you can safely stay in. 01:08:49.620 |
And again, I can't give a simple prescriptive to everybody, 01:08:52.240 |
but this is known to increase baseline levels 01:08:54.760 |
of dopamine significantly, in fact, double them or more 01:09:00.520 |
up to four, maybe even six hours into the day, 01:09:02.960 |
which is one of the reasons I suggest doing this 01:09:06.200 |
I happen to get into a cold plunge or take a cold shower 01:09:09.880 |
I do go outside and get my sunlight first sometimes. 01:09:16.440 |
I don't think it really matters which one you do first, 01:09:18.600 |
but you want to try and get both of those in early 01:09:20.760 |
in the day because you really want the catecholamines 01:09:28.360 |
So if you're doing your exercise early in the day, 01:09:30.360 |
there's no reason why it couldn't be done in concert 01:09:34.700 |
I recommend doing the deliberate cold exposure first 01:09:36.680 |
for the reasons we talked about a few minutes ago. 01:09:40.560 |
both prescription and over-the-counter compounds 01:09:42.980 |
that can indeed raise your baseline levels of dopamine 01:09:52.440 |
in terms of how quickly you metabolize dopamine. 01:09:56.640 |
And it depends on individual variation in how you manage 01:10:04.600 |
and here I'm talking about legal prescription drugs 01:10:07.880 |
for increasing dopamine are things like Ritalin, Adderall. 01:10:12.560 |
Modafinil and armodafinil also tap into this system. 01:10:17.880 |
which is the typical context in which you hear 01:10:23.400 |
for either clinical reasons like ADHD or for other reasons, 01:10:26.840 |
all of those compounds do significantly increase 01:10:29.320 |
baseline levels of dopamine for many, many hours. 01:10:31.780 |
That's absolutely clear and it's one of the major reasons 01:10:37.840 |
Then there are compounds that are sold over-the-counter, 01:10:40.040 |
things like amino acids, such as L-tyrosine itself. 01:10:43.120 |
That's a very commonly sold and used amino acid. 01:10:46.520 |
It's present in a lot of so-called pre-workout formulas. 01:10:50.940 |
am a fan of single ingredient supplements for the most part, 01:10:54.240 |
aside from foundational supplements like AG1, 01:10:57.280 |
which give you many, many micronutrients kind of all together 01:11:02.360 |
to consume each of those as individual ingredients 01:11:22.000 |
with supplements are using either L-tyrosine, 01:11:36.100 |
from the velvety outside coating of a certain bean. 01:11:41.060 |
but that's actually where it's found in nature, 01:11:49.440 |
having examined the scientific literature on macuna purines, 01:11:52.600 |
there is some evidence that it can increase dopamine, 01:11:55.240 |
especially in that tuber infundibular pathway, 01:11:58.500 |
because it can tap into some of the hormone-related functions 01:12:04.780 |
It might even increase libido, motivation, et cetera. 01:12:07.860 |
But the effects of macuna purines tend to be very much 01:12:18.300 |
not for increasing baseline levels of dopamine. 01:12:21.740 |
Now, it's likely different for people with Parkinson's 01:12:29.380 |
oftentimes they are prescribed things like L-dopa, 01:12:33.320 |
which is in the pathway to dopamine synthesis. 01:12:36.420 |
Or they are prescribed things like bromocriptine, 01:12:47.200 |
Those drugs can be used to increase baseline levels 01:12:52.280 |
they cause peaks in dopamine and troughs in dopamine, 01:12:57.060 |
They are not going to allow you to accomplish what you want 01:13:06.560 |
and then a crash that can include depressive symptoms 01:13:27.900 |
I'll provide links to a few of these studies, 01:13:36.340 |
under conditions where your baseline levels of dopamine 01:13:54.040 |
I'll provide a link to this in the show note captions, 01:14:07.940 |
allow people to rescue some of their cognitive function 01:14:21.200 |
and the second paper is perhaps more interesting 01:14:29.260 |
before a cognitive task or set of cognitive tasks 01:14:31.780 |
that involve a lot of multitasking and working memory. 01:14:34.340 |
Working memory, for those of you that don't know, 01:14:36.480 |
is your ability to maintain small batches of information 01:14:39.460 |
in your mind for relatively short periods of time. 01:14:41.980 |
So for instance, if I tell you my phone number, 01:14:44.100 |
or the phone number where I grew up, 4932931, 01:14:49.620 |
chances are you'll remember it for 30 seconds, 60 seconds, 01:14:56.020 |
A lot of the tasks that we do throughout the day 01:14:58.920 |
and working memory is very subject to interference 01:15:04.320 |
like looking at our phone or having a conversation 01:15:09.900 |
and this study shows that tyrosine improves working memory, 01:15:17.900 |
and they did a number of really nice experiments here. 01:15:20.660 |
It's, again, it's a small study, not that many subjects, 01:15:24.740 |
In fact, this is the paper that kind of set in motion 01:15:26.960 |
the domino of other papers exploring the efficacy 01:15:32.040 |
And they looked at working memory tasks, of course, 01:15:36.600 |
and they involve some interference of visual cues 01:15:40.180 |
and they saw some really interesting effects. 01:15:42.360 |
Basically, when we need to attend to multiple things 01:15:47.240 |
at the same time, L-tyrosine can help us do that, 01:15:54.920 |
is having your baseline levels of dopamine elevated 01:15:58.320 |
can really help navigate multitasking environments, 01:16:09.800 |
You might say, "Well, isn't multitasking stressful itself?" 01:16:13.320 |
but when we talk about under conditions of stress, 01:16:15.040 |
we're talking about people who are sleep-deprived, 01:16:18.160 |
other kinds of psychological or physical stress, 01:16:27.600 |
so high that actually I don't recommend them. 01:16:31.240 |
they did measure blood pressure and things of that sort, 01:16:33.360 |
but I want to caution you, I do not recommend, 01:16:38.500 |
following the dosages that were used in these two studies 01:16:44.940 |
They used 100 milligrams per kilogram of body weight 01:16:49.340 |
of tyrosine one hour prior to these cognitive tasks. 01:17:01.780 |
that would mean that had I participated in the study 01:17:08.940 |
I would have been given 10,000 milligrams of L-tyrosine, 01:17:21.620 |
but perhaps up to one gram, that is 1,000 milligrams, 01:17:24.680 |
or 1,500 milligrams, a gram and a half, of L-tyrosine, 01:17:28.140 |
taken 30 to 60 minutes before a cognitive or physical task, 01:17:45.020 |
in baseline levels of dopamine can be substantial. 01:18:02.780 |
Smaller people start with 250, larger, maybe 500. 01:18:06.580 |
Keep an eye on whether or not you're combining it 01:18:13.720 |
the bigger the trough in dopamine afterwards. 01:18:15.840 |
So pay attention to whether or not you experience a crash 01:18:20.760 |
if you're using a relatively low level of L-tyrosine, 01:18:34.880 |
that you're going to achieve these long lasting increases 01:18:46.940 |
and you disengage from the improper behaviors 01:18:49.220 |
as a first line of offense on any health goal. 01:18:53.560 |
So now you know how to set your baseline levels of dopamine 01:18:59.360 |
that baseline level of dopamine very carefully. 01:19:03.120 |
you want to avoid any kind of behaviors or substances 01:19:06.280 |
that are going to peak your baseline level of dopamine 01:19:11.520 |
or if you do engage in those types of behaviors, 01:19:23.500 |
You will be essentially in the quote unquote trough. 01:19:26.880 |
If, however, you find yourself in that trough, 01:19:31.580 |
that that trough will resolve if you wait enough time. 01:19:44.100 |
and as a consequence, when they feel that low, 01:19:53.860 |
following some quote unquote peak experience, 01:19:58.820 |
is thinking about what caused that peak experience 01:20:01.200 |
and then go back and try to re-engage in the behavior 01:20:07.000 |
But you now know that that is a terrible strategy. 01:20:10.200 |
In fact, that strategy will only lead to diminished peaks 01:20:20.680 |
to try and recapitulate, recreate that big peak, 01:20:24.640 |
Or even worse, people start stacking and combining 01:20:30.720 |
in order to try and obtain something like that initial peak, 01:20:34.680 |
when in fact, all they need to do, all you need to do, 01:20:39.480 |
because the way that the dopamine circuitry is arranged 01:20:42.300 |
is that it's not just about pleasure, as you know, 01:20:44.840 |
it's about motivation, desire, pursuit, and pleasure, 01:20:48.200 |
and it also has everything to do with pain and discomfort. 01:20:56.560 |
so a physical pain or an intense emotional pain. 01:21:02.440 |
We're going to talk about the pain associated 01:21:08.380 |
as a period in which pain and effort go hand in hand. 01:21:14.620 |
but I want you to just note that in your mind, 01:21:20.220 |
is how to leverage that pain and to use effort 01:21:23.040 |
as a way to not just get out of the trough more quickly, 01:21:25.880 |
but actually to get back to a higher level of baseline 01:21:30.880 |
Meanwhile, I really want to harp on this one point 01:21:38.120 |
so it could be a vacation or a night out partying 01:21:44.880 |
that lead to troughs or deficits in dopamine afterwards, 01:21:48.720 |
which can cause a sort of postpartum depression. 01:21:53.240 |
normally used to describe literally postpartum, 01:22:03.660 |
but it has hormonal aspects and other aspects as well. 01:22:06.740 |
But postpartum depression is also used to describe 01:22:22.600 |
in order to get out of that trough more quickly. 01:22:26.840 |
with the understanding that you will get out. 01:22:35.440 |
They don't realize that the dopamine circuitry 01:22:47.200 |
So dopamine is packaged in these little spherical things 01:22:50.520 |
Those vesicles are released from the ends of nerves. 01:22:55.620 |
we're talking about the nerves that originate, 01:23:00.200 |
and send their little wires up to the prefrontal cortex, 01:23:08.520 |
and that can take several days in order to replenish. 01:23:11.720 |
Just knowing that can help you through that process. 01:23:22.460 |
not just something to get you out of a trench 01:23:27.520 |
but actually what represents the holy grail of motivation. 01:23:31.520 |
Today, I'm going to talk about this pain effort process 01:23:34.520 |
as a very powerful way to get out of sticking points, 01:23:49.880 |
And this is not simply taking mechanisms from biology 01:23:54.320 |
Rather, this is leveraging mechanisms in biology 01:23:56.800 |
that are well-defined in the animal and human literature 01:24:03.680 |
but that have been shown in specific circumstances 01:24:06.760 |
to really allow people to engage in motivational pursuits 01:24:15.240 |
and in a way that never depletes their baseline of dopamine 01:24:18.120 |
to the point where they have to do a lot of extra work 01:24:21.760 |
and in a way that allows them to be really motivated 01:24:37.640 |
in order to be maximally motivated when you want to be, 01:24:44.260 |
I'd like to tell you about a classic experiment 01:24:46.400 |
that I've described once before on this podcast, 01:24:53.380 |
This was an experiment that was done at Stanford 01:25:01.360 |
The experiment involved observing a classroom 01:25:07.600 |
and observing which activities kids liked to do 01:25:20.520 |
they're probably not writing significant prose at that age, 01:25:26.340 |
And what the researchers did was observe the children 01:25:29.340 |
who selected by their own choice to draw pictures. 01:25:33.180 |
So there were some tables out with crayons and markers 01:25:36.440 |
and there were some kids that would just naturally go 01:25:44.360 |
these children elected to use their free time drawing, 01:25:50.100 |
And then what they did was they started introducing rewards 01:25:55.600 |
They started putting a gold star or in some cases, 01:26:06.580 |
They're not only doing an activity that they like, 01:26:10.460 |
So you can probably see where this is all going. 01:26:12.300 |
What they were doing was they were increasing the amount 01:26:17.000 |
And again, in parallel experiments done with adults, 01:26:19.980 |
if you take adults who enjoy a particular activity, 01:26:23.080 |
and then you start rewarding them for that activity, 01:26:25.280 |
especially when you surprise them with a reward 01:26:29.780 |
they report that being a much more pleasurable experience 01:26:36.360 |
and in the experiments with adults done later on 01:26:42.600 |
and then they observe what percentage of their free time 01:26:53.180 |
that the children elected to do this activity 01:26:57.920 |
In other words, their total satisfaction or desire 01:27:03.720 |
dropped below what it was prior to ever receiving a reward. 01:27:07.160 |
And again, this has been repeated in a variety of contexts 01:27:09.560 |
in different populations, different cultures, 01:27:11.000 |
different countries, men, women, boys, girls, 01:27:16.700 |
So what this tells us is everything you already know, 01:27:24.880 |
and you carrying it out and it being pretty good, 01:27:30.760 |
I always like to joke that the nervous system 01:27:37.480 |
It can either be yum, yes, I really like that. 01:27:44.280 |
What the scenario led to where rewards were received 01:27:46.840 |
for an activity that people already like to do 01:27:55.900 |
And that all reflects a drop in baseline dopamine, why? 01:28:00.140 |
Because the activity that the children or adults liked 01:28:03.860 |
combined with the gold star or the monetary reward or praise 01:28:11.180 |
compounded to create a bigger peak in dopamine 01:28:16.740 |
And if you're already wondering whether or not 01:28:22.740 |
So essentially what I described all matches precisely 01:28:34.060 |
allow baseline levels of dopamine to return to normal. 01:28:37.140 |
And of course the amplitude of that dopamine peak 01:28:40.220 |
has been varied by giving more money or less money 01:28:43.780 |
Nearly all the different derivations of the experiments 01:28:49.460 |
that we've been talking about during this episode 01:28:51.580 |
all played out exactly as one would have predicted 01:28:54.620 |
based on the neural circuitry and the dynamics of dopamine. 01:28:59.860 |
to make sure that any activities that you enjoy to do, 01:29:02.860 |
whether or not you enjoy it a little or a lot, 01:29:11.520 |
that you don't start layering in or attaching reward 01:29:15.300 |
or other sources of dopamine releasing behaviors 01:29:22.080 |
Or if you do, that you don't do it terribly often. 01:29:34.020 |
and you'll know people that will have different examples. 01:29:39.280 |
I know to some people, this might seem foreign, 01:29:48.220 |
that doesn't like the experience of exercising, 01:29:51.220 |
but likes the feeling afterwards, quote unquote. 01:30:07.460 |
who likes to do hard things across the board. 01:30:10.000 |
There are plenty of difficult things in life that I dread 01:30:19.700 |
resistance training and running in particular, 01:30:23.180 |
both give me a yum, yes, I love this kind of feeling. 01:30:26.940 |
And yes, it persists for me quite a long while afterwards, 01:30:30.700 |
both for sake of the way that it changes my neurochemistry, 01:30:37.820 |
I discovered that if I drink a cup of black coffee 01:30:41.080 |
or an Americano or a double espresso or some yerba mate, 01:30:45.080 |
that my workouts can be quite a bit more intense. 01:30:50.440 |
that if I were to take a pre-workout energy drink 01:31:00.300 |
and perhaps even 500 milligrams of L-tyrosine 01:31:06.300 |
then yes, absolutely, I really liked those workouts. 01:31:11.620 |
I could exert even more effort, put on some music, 01:31:19.540 |
that I could export that protocol of caffeine, yerba mate, 01:31:23.960 |
and various supplements to my cognitive work. 01:31:29.920 |
when I was doing experiments with my hands in those days, 01:31:38.620 |
all of those behaviors compounded with my love of exercise 01:31:41.820 |
and my love of doing science and gave me these big peaks 01:31:45.940 |
in what to me felt like even important experiences. 01:31:52.200 |
They were just so, so peak in their nature, which was great. 01:31:58.960 |
However, while it did not create a dependency 01:32:05.940 |
supplements, et cetera, what I noticed was that in the days 01:32:20.820 |
And then if I kept up those behaviors consistently 01:32:24.740 |
and I was consistently adding in these other, 01:32:28.420 |
dopamine releasing or stimulating behaviors and substances, 01:32:32.780 |
that my enthusiasm for physical training or running 01:32:36.680 |
or for doing experiments actually started to diminish. 01:32:39.580 |
And this was really discouraging to me at the time 01:32:41.500 |
because I started to think, okay, maybe I'm burnt out. 01:32:47.500 |
There is something called adrenal insufficiency syndrome. 01:32:52.060 |
by way of too much adrenaline, epinephrine and norepinephrine, 01:32:57.120 |
There's no such thing as adrenal burnout per se. 01:33:02.740 |
When in fact, it's now obvious to me what I was doing. 01:33:12.060 |
for things that I already enjoy doing as behaviors, 01:33:20.100 |
So what this means is not to avoid taking things 01:33:24.940 |
or doing things that amplify your amount of dopamine, 01:33:28.260 |
but to be very cautious about how often one does that 01:33:31.260 |
and how many different dopamine stimulating behaviors 01:33:40.100 |
or stacking those things in and around behaviors 01:33:45.400 |
I was essentially just creating another version 01:33:53.460 |
I was basically just doing the exact same thing. 01:33:55.740 |
And when I realized that and I changed my relationship 01:33:59.680 |
to those compounds, I didn't eliminate them all together, 01:34:05.300 |
that I didn't need to double up on yerba mate 01:34:10.900 |
Sometimes I would do one, sometimes I would do the other. 01:34:15.580 |
It's rare that I ever do any kind of physical training 01:34:21.900 |
So that's fine, doesn't interfere with my sleep. 01:34:26.420 |
but if I'm in a weight trainer, I'm going to run. 01:34:28.920 |
I tend to drink coffee beforehand or have yerba mate. 01:34:31.700 |
Or if I occasionally, meaning about once every third, 01:34:36.460 |
sometimes every other, but usually about every third workout 01:34:42.380 |
maybe occasionally, maybe every third or fourth workout. 01:34:47.220 |
And these are resistance workouts, mind you, not running. 01:34:52.340 |
or more typically 500 milligrams of phenylethylamine. 01:34:55.780 |
And very, very rarely, maybe once every two or three months, 01:35:01.980 |
But of course, I'm always mindful to also include workouts 01:35:16.020 |
that I use each day to function like many people. 01:35:23.880 |
I talked a lot about this on the episode in caffeine. 01:35:30.020 |
I would say be very cautious about stacking and layering 01:35:42.020 |
that can engage in these intrinsically joyful activities 01:35:45.180 |
for you, these activities that you're really motivated to do 01:35:50.580 |
without the need to layer in additional dopamine 01:35:53.600 |
releasing mechanisms or compounds or activities, 01:36:00.200 |
because then you are essentially making yourself 01:36:11.580 |
can hold on to that intrinsic pleasure and motivation 01:36:19.340 |
There is no pill or bottle or potion or motivational speech 01:36:22.340 |
or podcast or book that can replace intrinsic motivation. 01:36:27.340 |
Intrinsic motivation is perhaps the holy grail 01:36:33.080 |
because it encompasses so much of what brought us 01:36:37.180 |
and also what brings each and every one of us 01:36:43.620 |
without the need to layer in additional tools, 01:36:46.220 |
well then you have really tapped into the source. 01:36:54.460 |
that when we hear about chi from Eastern medicine 01:36:57.560 |
or we talk about motivation drive and pursuit 01:37:05.660 |
maybe in my podcast episode with the one and only Rick Rubin, 01:37:30.300 |
And if we can do that with an intrinsic sense of pleasure, 01:37:41.460 |
about trying to protect the things they already enjoy 01:37:48.740 |
Most people are thinking about how they can engage 01:37:52.540 |
and pursue things that are less than pleasureful to them, 01:37:56.020 |
or how they can continue to engage in motivated behaviors 01:38:00.200 |
when the going gets tough, or, and this is a big one, 01:38:15.120 |
plus an additional dynamic that we haven't quite talked about 01:38:27.740 |
which is when effort starts to become the reward itself. 01:38:32.740 |
In other words, when friction becomes the reward. 01:38:43.260 |
no matter how daunting, to successful completion of that goal 01:38:47.880 |
while experiencing what essentially will feel like pleasure 01:38:51.940 |
Now, that doesn't mean it will be bliss the entire time, 01:38:54.780 |
but what is very possible is to leverage the dynamics 01:39:02.080 |
in order to not just maintain your baseline level 01:39:09.900 |
or other kind of overthinking trenches very quickly 01:39:23.780 |
and research papers from my colleague, Dr. Carol Dweck 01:39:34.060 |
who have leveraged the so-called growth mindset 01:39:36.900 |
as a tool that young people and adults alike can use 01:39:45.900 |
is to adopt the mindset that if you can't do something 01:39:52.340 |
that you can't do it or can't do it well yet. 01:39:57.500 |
And there are a number of different tools and techniques 01:40:13.360 |
when we expect ourselves to be able to motivate 01:40:16.760 |
or when we expect ourselves to be able to perform 01:40:30.300 |
motivation and outcomes, reward prediction error. 01:40:37.840 |
or we want to be able to do this physical skill 01:40:43.440 |
or get the mate we desire or make the relationship work 01:40:49.340 |
And then we get the outcome that we don't want 01:40:51.600 |
and our confidence, for lack of a better word, 01:40:58.080 |
where we are not motivated, we are A motivated. 01:41:14.080 |
We know that if we put in the effort, we'll get there, 01:41:20.760 |
Now we could be quote unquote, not feeling great, 01:41:23.600 |
not feeling motivated because our dopamine baseline is low. 01:41:40.620 |
to those foundational things that we talked about earlier, 01:41:42.740 |
whether or not you are engaging any other of the tools 01:41:47.180 |
to see if you can get into a motivated state. 01:41:59.960 |
Well, then there's a very potent set of tools 01:42:02.100 |
that you can leverage to overcome states of lack 01:42:07.540 |
and indeed can help you deal with things like overthinking 01:42:33.340 |
and it's a craving or wanting for a specific state 01:42:39.440 |
that is different than the one that you're in. 01:42:42.880 |
And as you recall from earlier in the episode, 01:42:51.460 |
the motivation to go forward and seek some goal, okay? 01:43:02.000 |
or when we just sort of can't seem to get in gear, 01:43:08.800 |
I already told you earlier, you can just wait, 01:43:15.620 |
They start doing other things that are less painful 01:43:21.320 |
when they are trying to get into gear to go work out, 01:43:23.960 |
'cause I realize not everyone wants to do that, 01:43:33.360 |
and indeed they, would not consider pleasureful activities. 01:43:37.040 |
They start, for instance, cleaning the house. 01:43:42.000 |
that normally are not intrinsically pleasureful for them, 01:43:49.320 |
that they quote unquote need to do or ought to do, 01:43:59.840 |
In other words, rather than be in the painful state 01:44:08.640 |
to give them the sense that they're completing things. 01:44:20.120 |
in order to get engaged enough or motivated enough 01:44:23.380 |
to study or work out or whatever activity it is 01:44:25.520 |
that they're trying to avoid through procrastination. 01:44:34.240 |
And second of all, a lot of people will use this as a tactic 01:44:46.120 |
to leverage their mental and physical resources 01:44:52.720 |
How do I understand the inner dynamics of it? 01:44:54.860 |
Well, part of that relates to my work as a neurobiologist 01:44:57.460 |
and reading the papers that I'll mention to you in a moment, 01:45:00.280 |
but it also relates to the fact that I'm somebody 01:45:05.060 |
right up until the sort of last minute possible 01:45:08.320 |
to complete something for activities that I don't want to do, 01:45:11.180 |
something I've been working on my whole life. 01:45:24.340 |
towards leveraging our way out of procrastination. 01:45:31.140 |
because I've told you probably a dozen times now, 01:45:33.380 |
that the depth of the trough after a dopamine peak 01:45:39.400 |
and how steep it was, how quickly that peak occurred. 01:45:42.680 |
It turns out that not only is the depth of the trough 01:45:46.520 |
but the rate at which you get out of that trough 01:46:01.280 |
you're just not feeling motivated, you're procrastinating. 01:46:04.640 |
You may think, okay, the thing to do here is something, 01:46:08.600 |
I'll clean the house, I'll take care of some bills, 01:46:16.000 |
generally don't work or at least don't work quickly, 01:46:21.560 |
to get something done, or you just don't get it done 01:46:39.000 |
in other words, doing something that's more effortful, 01:46:46.680 |
out of that dopamine trough much more quickly. 01:46:49.920 |
So what do I mean you want to put yourself in a state 01:46:51.920 |
that's worse than or harder than the state that you're in 01:46:58.800 |
but I'm going to say it for the first time now. 01:47:02.360 |
I do not mean doing any kind of tissue damaging 01:47:08.400 |
or anything of that sort that's going to render you injured 01:47:16.760 |
What I'm referring to is the fact that, for instance, 01:47:19.760 |
if you're feeling amotivated, but you find yourself 01:47:22.440 |
cleaning the house as a way to procrastinate, 01:47:25.200 |
you can say, well, cleaning the house is harder 01:47:29.880 |
but actually in that moment or in those moments, 01:47:32.960 |
that's not the case or else you wouldn't be doing it. 01:47:36.680 |
The reality is that the dopamine system works 01:47:40.880 |
according to what feels hard or easy in the moment. 01:47:44.540 |
In other words, if you're feeling amotivated, 01:47:46.940 |
you need to do something and put yourself into a state 01:47:55.720 |
feeling amotivated or you find yourself tending to tasks 01:48:16.160 |
that puts your body into a very different state. 01:48:18.580 |
So here again, I'll default to the obvious one, 01:48:20.600 |
which is something like cold shower or cold immersion, 01:48:32.420 |
That pain causes a rebound out of that dopamine trough 01:48:37.700 |
if you had just stayed in that amotivated state 01:48:43.080 |
that for whatever reason felt like it required 01:48:48.660 |
Your limbic system is always in this dialogue 01:48:50.660 |
with your forebrain and limbic friction goes two ways. 01:48:57.820 |
And so you have to quote unquote, motivate to do it, 01:49:02.300 |
Or limbic friction can be that you're nervous and scared 01:49:06.820 |
and you have to calm yourself in order to lean forward 01:49:09.020 |
into action in order to do that thing despite the anxiety. 01:49:12.340 |
I realize this can be a little bit confusing as a concept. 01:49:27.740 |
There are a couple of different techniques to doing this. 01:49:30.220 |
Assuming you've taken care of all the baseline stuff, 01:49:32.820 |
all the foundational stuff we talked about earlier, 01:49:40.820 |
Obviously those things are quote unquote, easier for you. 01:49:49.140 |
The typical advice would be just exercise for one minute. 01:49:54.800 |
Okay, just get one minute of exercise or five minutes 01:50:02.220 |
that allows you to then move to the next milestone. 01:50:08.460 |
when I say that you're in a state of lack of motivation 01:50:14.400 |
And you need to put yourself into a more painful, 01:50:34.920 |
and they're just like, okay, I'm still in the trough. 01:50:41.180 |
it makes sense to do something that's tangential 01:50:43.560 |
to the whole path that you're trying to pursue, 01:50:52.160 |
And when I say worse, I don't mean picking some task 01:50:58.300 |
I mean, literally thinking about what would be worse 01:51:04.980 |
or psychological damage, what would be worse? 01:51:07.480 |
Well, cold water would be worse for many people, 01:51:14.340 |
for lack of a better way to put it, really sucks, 01:51:28.700 |
to your baseline level of dopamine more quickly. 01:51:31.420 |
Now, for some people, that will be deliberate cold exposure 01:51:35.080 |
And I have to tell you that if you're cringing 01:51:44.100 |
and therefore represents a great tool for you. 01:51:48.220 |
I really need to do, should I just simply wait 01:51:55.820 |
Will a deadline eventually surface that will trigger me 01:52:01.780 |
that will allow me to complete what needs to be done? 01:52:06.900 |
But better would be to get out of that amotivated state, 01:52:13.860 |
you need to leverage something that's painful. 01:52:15.720 |
So for instance, I heard a beautiful lecture recently 01:52:18.580 |
done by Dr. Anna Lemke at Stanford School of Medicine 01:52:21.580 |
discussing dopamine and some of the things in her book 01:52:26.460 |
And somebody in the audience asked her the question, 01:52:31.660 |
Now, earlier we talked about how non-sleep deep rest 01:52:33.900 |
and yoga nidra has been shown in the scientific literature 01:52:37.840 |
But I also mentioned earlier that classic forms 01:52:40.620 |
of meditation, whether eyes open or eyes closed, 01:52:43.260 |
so-called open monitoring or closed monitoring meditation, 01:52:52.940 |
especially people who find it hard to meditate 01:53:01.300 |
Getting into meditation and staying in meditation 01:53:05.700 |
So if you find yourself in a state of procrastination, 01:53:08.460 |
oftentimes a brief five to 10-minute meditation 01:53:11.540 |
where you absolutely do not allow yourself to do anything 01:53:14.380 |
besides close your eyes, focus on your breath, 01:53:17.420 |
and when your mind drifts, get back to your breath, 01:53:19.780 |
is not only extremely difficult and extremely frustrating, 01:53:25.940 |
but it's often difficult and frustrating not just to do, 01:53:35.680 |
because it's just not a natural state for us to be in. 01:53:40.880 |
In fact, it qualifies as a basically available 01:53:44.200 |
almost anywhere, anytime type of effortful activity 01:53:51.880 |
deliberate cold exposure, well then, perfect. 01:54:01.360 |
Now, there are numerous examples I could give, 01:54:17.880 |
keeping in mind that the goal is not what you accomplish 01:54:26.780 |
in that five to 10 minute little bout of effortful 01:54:39.460 |
In other words, taking yourself from that trough 01:54:45.540 |
because in steepening and deepening that trough, 01:54:51.520 |
to normal and even elevated levels of baseline dopamine 01:54:59.200 |
And in doing that, you will quickly find yourself 01:55:08.200 |
that's sort of a more of a subjective cognitive learning, 01:55:11.020 |
but it actually taps into the very neurochemical system 01:55:14.540 |
that allows you to then feel motivated and capable 01:55:18.940 |
which is the thing you're really concerned about after all. 01:55:36.200 |
that is so vitally important to motivation for any goals. 01:55:40.860 |
Talked about the relationship between peaks and troughs 01:55:49.240 |
as well as ways to protect that baseline level of dopamine. 01:55:53.940 |
out of states of procrastination and a motivation 01:55:58.100 |
by not just waiting out those troughs and dopamine, 01:56:01.700 |
but actually making those troughs and dopamine steeper 01:56:07.320 |
and things that we really don't want to do in those moments, 01:56:13.140 |
we can get out of those dopamine troughs more quickly 01:56:15.900 |
and back to our dopamine baseline or even above baseline. 01:56:23.980 |
which is to be able to learn to attach reward 01:56:35.340 |
of these different stressful chemicals within our body. 01:56:38.380 |
I realize this was a lot of information and yet throughout, 01:56:41.420 |
I've tried to highlight tools that you can use 01:56:44.700 |
to nutritional supplementation tools, cognitive tools. 01:56:47.780 |
And keep in mind that all of these different segments 01:56:52.060 |
So if you feel the need to go back and listen to any of these 01:56:58.300 |
So simply look for the timestamps in the show note captions. 01:57:01.300 |
