Psychologist Daniel Keating on Stress, Anxiety & Adolescent Mental Health

An Interview with Psychologist Daniel Keating

Daniel Keating, Ph.D. is a Professor of Psychology, Psychiatry, and Pediatrics at the University of Michigan, Ann Arbor. He specializes in adolescent development and adolescent psychology.

Mai Tran:  Awesome. Okay. Hi, everybody. Thank you for joining us today for another interview in our Seattle Psychiatrist Interview series. My name is Mai and I'm a research intern at Seattle Anxiety Specialists. We are a Seattle-based psychiatry, psychology and psychotherapy practice specializing in anxiety disorders. Today, I'd like to welcome Dr. Daniel Keating.

Dr. Daniel Keating is a professor of psychology, psychiatry, and pediatrics at University of Michigan, Ann Arbor. And Dr. Keating is an expert in developmental psychology and he specifically focuses on the integration of knowledge on developmental processes, social factors, and population patterns in developmental health and how they affect individual and population health.

He's made significant contributions to research in the field and some recent academic articles that include "Cognition in adolescence and the transition to adulthood", "The Kids Are Not All Right: Adolescent Sadness, Hopelessness, and Suicidality are Skyrocketing. What to do?" And his book "Born Anxious: The Lifelong Impact of Early Life Adversity - and How to Break the Cycle."

All right. So before we get started today, can you please tell us a little bit about yourself and why you initially became interested in studying developmental psychology?

Daniel Keating:  Sure. So it's a long story, but I'll condense it. I did my graduate work, my PhD, at Johns Hopkins. And the work that I was doing at that time was really focused more on individual differences rather than developmental differences. But the focus was on early precocity, that is to say individuals who were advanced in during their early adolescence in terms of their math and scientific expertise and measured in a variety of ways. And so there was a developmental component to that obviously in terms of how people came to those things. There was also one of the giants in the field of developmental psychology was also was a professor at Hopkins when I was there, Mary Ainsworth, who is responsible for a lot of the work that's been done on attachment and the sequelae of attachment from early childhood. So I managed to come by some of that knowledge through her being on the faculty.

My first tenured position was at the Institute of Child Development at the University of Minnesota and increasingly began to focus on a variety of things having to do with how the differences develop as opposed to just that they exist and how we might deal with them.

And then I subsequently moved to the University of Toronto and was invited then somewhat out of the blue to take on the task of setting up one of their networks in a think tank called the Canadian Institute for Advanced Research. And it was on human development and it went across the board from sort of molecular and single-cell neuroscience all the way through anthropology, sociology, and so forth.

And then that really sort of provoked my interest in how both, individually, how the things develop, but also in terms of the population impact of a variety of things, focusing as I think the evidence led us to look at what are the circumstances that lead some individuals to thrive and other individuals to struggle. What are the kinds of things that are going on? And, of course, in that context, early life adversity plays a major role. So that's the very thumbnail version.

Mai Tran:  Yeah. And I also recall reading some of that in your book "Born Anxious."

Daniel Keating:  Right.

Mai Tran:  And I'm really interested in one of the concepts that you kind of laid out in the book, social epigenetics, and the links to stress dysregulation. So can you explain what these are to our audience in layman terms?

Daniel Keating:  Sure. So let me break it apart a little bit. So epigenetics is a relatively new field of study, certainly as it bears on behavior. And basically, the idea there is that of course we all know that the DNA you get at the moment of conception is the DNA blueprint that you'll carry throughout your lifespan, that doesn't change. But what does change is when we take a closer look at how genes function, and among the things that how genes work, basically, is that they're, if you think of them as little manufacturing centers and they're producing certain things that they're designed to produce. All of them have a region, it's called a number of things, the promoter region or the regulatory region of the gene. And what that does is in a sense, whatever it is that that gene does, the promoter region tells us when to do it, how much to do it, when to turn off, when to turn on, et cetera.

That portion of the gene is malleable. It can be affected by a variety of different things. It can be changed by physical exposures like toxic exposures. One of the best documented is in terms of the impact of cigarette smoking makes a lot of epigenetic changes that are thought to play a significant role in the development of cancer, for example. But the breakthrough from our point of view is the other term, social. And basically what was emerging and discovered and since has exploded is in really around 1999, 2000, was that first with animal studies and later with human studies, it turns out that social experiences, especially stressful experiences also cause epigenetic changes.

And some of the most important of those, we don't know all of them for sure by now, but some of the most important of them, earliest documented and most frequently documented are changes to the stress regulation system, which is basically what causes our stress system to respond, how much does it respond, how long does it take to go back to baseline and so forth. And so obviously, I think we all know that a stress system is essential for survival. We need to have it, but when it gets overly engaged, often because of stress exposure either in infancy or even in the womb, that then can make an epigenetic change that can carry forward in terms of how that stress system works.

Mai Tran:  Right. That's really interesting. And I am sure that a lot of people would be curious to know as what specifically are some of the most common environmental factors that can cause changes to your epigenetics?

Daniel Keating:  Right. Well, as I say, the stress response and the stress influence on this is the one that's, at this point, the best understood, although it's still not by far completely understood. But basically what we're looking at there is exposure to stress in a variety of ways. And it depends, of course, on the age of the organism.

So in the womb it's relatively straightforward in the sense is that if for whatever reasons the mother to be is experiencing high levels of stress or adversity, all the way from worries about sort of getting the material necessities of life or shelter, food, that kind of thing, or more seriously if they're in an abusive relationship and have stress because of that. So kind of those as the extremes, those, if they are sufficient, or if the mother's response to them is sufficient, that it produces a level of cortisol, which is one of the main products in the stress response system, if that cortisol is at a sufficiently high level, it can break through the uterine barrier and enter into the womb. And if those circulating chemicals then include cortisol at a sufficiently high level, they can trigger the epigenetic changes in the fetus even before they're born. So that would be one pathway that happens.

After being born, the first year to two are the most sensitive periods. And stress can come in a variety of ways. It's largely around the absence or a dysfunctional nurturing of the infants. So if they're not being taken care of, whether it's in terms of meeting physical needs or meeting comforting, nurturing needs like being held and that sort of thing, that then can elevate the stress level as well.

And then as individuals get older, those are the most sensitive periods, but it can happen later as well. But basically what that does is set up the stress response system, that high stress during those critical periods, sets up a system whereby the organism learns, in a sense, biologically, that it's probably a not very safe world out there. It's a dangerous world out there. And so if you're going to survive in a dangerous world, what you want to do is to have a stress response system that's more like a hair trigger. Even things that most folks might see as neutral, they would regard as dangerous and do that and respond excessively. And then excessive cortisol has a lot of negative consequences behaviorally, health-wise, and so forth.

The other thing I just want to point out is that we often speak of it, and I try to avoid it, but it's not easy, is to think of this as a problem or a deficit or whatever. I think it's better to think of it as an adaptation to what the organism perceives as a dangerous environment. So if in fact you are in a highly dangerous environment, having that kind of quick trigger stress response and immediately engage in fight or flight is perhaps survival, helpful.

And it doesn't do a whole lot of good for your body, but it does in fact maybe keep you alive. So think of the predator in the bush or a tiger in the bush. If you're in an area that's relatively safe and all of a sudden it's invaded by new predators, organisms that respond quickly to that are more likely to survive than individuals who don't. And so we have to understand, although in our environment, that's typically not the kind of environment we're living in, but the system doesn't know that, and so it doesn't know where the stress is coming from. And so it's typically more problematic for individuals with that stress response dysregulation, even though it really is evolutionarily an adaptation to dangerous environments.

Mai Tran:  Right. Yes, that's really interesting to hear. And speaking of that kind of stress adaptation, how would you describe what it feels like to experience that kind of constantly elevated stress response or as you called it in the book, a stress response system that is constantly locked on?

Daniel Keating:  Right. So basically the experience of it is just an elevated version of what all of us experience at one time for another. So if we're all we're anxious about a big test coming up or we're fearful about something that's happened, we respond with... And one of the adaptive purposes of cortisol is to activate your system. So it's actually in many ways beneficial. It focuses attention, it increases heart rate, lung capacity and all those other sorts of things that make it possible to react and to do stuff. In a system that is more or less locked on, not totally locked on, but sort of on a continuum, it's certainly more so. You have that experience a lot all the time. And so you're kind of on edge, nervous, agitated, concerned about things that may not really exist as dangerous to you or as problems or challenges for you, but you perceive them to be so.

And so it's important to recognize that, of course, once you've activated that, and it can be an internal activation, it doesn't have to be an external threat. And that is a lot of the anxiety disorder, you're activating a system that's actually not in response to some challenge in the real world. So if you're doing that a lot, you're constantly kind of on edge or restless or concerned, and the body doesn't know whether that stress response has been triggered by an internal thought or an external threat. It activates and then it causes these changes. So essentially you're looking for a flight, fight, or you're looking to run away, even though nothing particularly problematic is actually out there in the external environment to provoke it.

Mai Tran:  Yeah. And I know that sometimes it can get pretty serious. So what do you think would be the short and long-term consequence of that?

Daniel Keating:  Well, they're very similar in some ways in the sense that they're across the board. So it can have behavioral consequences. So you are quick to anger, you go into reactive cycle more readily than other individuals, which then certainly doesn't endear oneself to people around you because they can't predict your behavior, what's going to set you off. So there's a behavioral consequence, which is then because of the accumulation of various kinds of things, can cascade into various kinds of psychopathology, externalizing being kind of the excessive fight response or internalizing being the excessive flight response going inside or at another level of freeze response where you just don't react at all to anything because it seems too dangerous. So there's all those behavioral consequences, there's mental health consequences. And I think what has now started to enter the common understanding is that it has massive health consequences.

So individuals, some of the earliest studies, this is prior to epigenetics, but some of the earliest studies showed that the sort of fetal environment is predictive of cardiovascular risk in your fifties and sixties. So it is a lifespan kind of thing. We now understand that most of that is occurring not only, but largely through the stress response system. So one of the superb scientists in this area, Bruce McEwen, who passed away relatively recently, is responsible for a lot of that work and showing why it is at a stress response system that is dysregulated, remembering it's adaptive in some sense, but this kind of dysregulation provokes this kind of sustained cortisol level. And his term for that was "allostatic load". You're carrying too much around all the time. And as it turns out, cortisol can be toxic to almost all organs of the body.

So essentially it can show up in health as cardiovascular problems, as a whole host of other kinds of metabolic problems, and so forth. The link to cancer is not that clear. There's probably a link, but it's not as clearly strong because a lot of those come from exposures to carcinogens in one version or another, physical exposures. But a lot of these things that we, sort of at a population level, of course, we wouldn't know these things if we didn't look at populations. For a given individual who shows up with a medical problem at some point in their life, what the decades long history that brought them there, we don't know all of that. But if we look at populations, it gives us an idea of what kind of consequence or sets of consequences it has.

Mai Tran:  Right. Yeah. And what do you think when the stress response becomes maladaptive to us, what do you think is a good way for us to receive help or help ourself in those situations?

Daniel Keating:  Right. Well, for that, I think the place that we would be looking is into the literature on resilience in one way or another. And so the literature on resilience has mushroomed in recent years in parallel with our better understanding of trauma and stress and so forth.

And again, this is far from settled issues, but I think that if we look at the big picture, one of the big, and probably the most well-documented way to redirect that maladaptive pathway is through social connections. That is through positive social connections. And so that can come in many, many different forms. So it can come in childhood by sort of having a responsive extended family network who can help to deal with issues that are not working well, parent, child. And so that's one example where it can happen. We have good evidence that particularly in late adolescence and early adulthood, close friendships, intimate friendships, romantic relationships can have a similar effect, if the romantic or friendship partner is supportive and has the capability to help one learn how better to regulate these sorts of things.

And there's very good evidence of this in many ways, what is come to be known as a Romanian orphanage study. Looked at infants who, for a variety of political and economic issues at that time, there were many, many orphans who were not being cared for. There was large numbers of them, a government policy of promoting birth but not supporting families. And basically those individuals, those infants were in situations where basically the most minimal things to keep them alive were done. So they were provided with physical nourishment, food, water, milk, that kind of thing, but not much else. They were pretty much left unsupported or non-nurtured.

What we know is that those individuals, certainly up to about age one, maybe a little after that, if they were adopted from those circumstances, and there are some, it's a very tragic story, but individuals who were adopted into highly nurturing families by around age six or five or seven, looked pretty much normal. They didn't seem to have that stress dysregulation going on, or at least it wasn't affecting their behavior in major ways.

After that time, they pretty much do have lifelong consequences. So there's something about it becoming biologically embedded during sensitive periods that make it difficult to deal with. But the way that it does, those circumstances where it does work almost always involves some level of a change in the social network of closer affiliations and so forth. And so I think that stands out as the most well-documented one. Certainly in terms of particularly in childhood, things like parent-child therapy can help, right? To establish if there's enough capability for change to change what is a dysfunctional relationship in a direction that is encouraging of relational health, for example, can have a similar kind of effect, but that's of course a person to person thing as well. It's just guided person to person kinds of interactions.

The other one that stands out, and it goes by so many names, it's hard to give a comprehensive one, but it has aspects of the mindfulness approach, aspects of acquiring a set of purposes and goals and values and wanting to do some particular kind of thing. Having a focus can also be helpful and restorative in terms of giving some shape and substance to what it is that one might want to do.

Mai Tran:  Right. Thank you. That was a very extensive answer. And now I'd like to move on to your recent Psychology Today article, which is really useful. It takes on the really crucial topic of dealing with adolescent sadness, hopelessness, and suicidality in a society that keeps on triggering these responses. You mentioned a misdirection to avoid is to ignore the existential stressors in favor of the seemingly more manageable phenomenon of screen time and social media when you were discussing the effects of issues like gun violence. So how do you think we can offer help as loved ones for adolescents and prevent this epidemic of adolescent sadness, hopelessness, suicidality as these situations keep on occurring and we don't really have control over it?

Daniel Keating:  Right. So I think one of the things is that I largely think the high focus on social media as the cause of all of these mental health problems in teens is misdirected. Which is not to say that it might not be harmful for some individuals, but careful studies with large samples followed longitudinally essentially say that if there is an effect at all of screen time and social media, it's really kind of small. It's not that big a deal for most individuals. If you break it down a little bit further, it does look as though individuals who may have preexisting difficulties or challenges may accentuate it. On the other hand, there are individuals for whom it is beneficial, who might have difficulty maintaining positive relationships, and social media may well be a boon to them. And of course, we saw examples of that every day during the pandemic where teen peers are just enormously important and salient. We can see it in the brains to teens.

If you say, "No, that's it. You can't have any connection," it is likely to be very dangerous. So individuals who were in social groups and maintained them through a variety of uses of social media was beneficial. So I think we have to weigh that. And it's probably just for the vast majority of kids in the middle, it doesn't matter one way or the other, right? Particularly so, or at least we don't have any evidence that it does. So there may be effects, but the effects are relatively small. My problem with that view that it's the source of so many of the problems is that it blinds us to the fact that the other problems are much more important. So I've started to call this a stress pandemic. And it's not just in the US, it's not just teens. It really is a kind of universal phenomenon. And it's hard to ignore the fact that that's because so many things are going wrong, taking the US as our prime example, right?

Concerns about climate change... Now that will probably affect youth more because they understand they're going to bear the brunt of it than the folks who are making decisions, who are the CEOs of oil and gas companies or whatever. So they're going to suffer. So they're aware of that. Growing up, figuring out how to avoid active shooters is bizarre, right? That's just an enormous stressor. It is a huge stressor. And you can go on and on with other kinds of things. And so what I think we need to think about are at two distinct levels of this. And one of which we should focus on and we focus on a lot, but we don't focus on the second one.

The first one, Desmond Tutu, or at least a quote attributed Desmond Tutu, is that in addition to trying to scoop folks out and help them who are coming down the river with all sorts of problems and try to support them, we need to go upstream and find out why it's happening. And so the downstream stuff, I think, is what we are attempting to do when we do sort of psychological interventions, when we try to create therapeutic circumstances for individuals to figure out how to do it, and more broadly, sort of communicating effective techniques for coping with stress.

And of course, we know that some individuals are resilient without intervention, they wind up doing fine. The problem with relying only on that is that then we can tend to blame the individuals who don't succeed, who have had long histories of problems and stressors, and most of them without some kind of major support will not succeed. And so we don't want to blame them for that. We created the burden. We don't want to blame them for carrying the burden and not being able to overcome it on their own. And I think the techniques there, a lot of them are out of the resilience literature that we just talked about, which can be therapeutically supported by intervention, clinical, if it's serious enough by prevention programs or just general education. So you can have universal programs, targeted programs, clinical intervention programs, all of which are helpful, but it's not helpful enough to save everybody or the vast majority of people.

And the more folks who are coming downstream, succumbing to the stress, the less effective we are in terms of how many people we can help. The upstream problems are what we tend to ignore. Why have we created a world in which the stress level is so high? And I think if we fail to attend to that, it's a problem. That, by the way, in terms of the resilience literature about the second issue around purpose and goals and so forth, I do think that for youth, for teens and young adults and so forth, I do think that a lot of them have figured out that focusing on trying to change the big picture is actually beneficial individually. They feel efficacious, they connect with other people with similar views and so forth. And we often talk about adolescent risk-taking, which is another area that I'm working on now as a negative thing. And we're concerned about it when it is a health risk like reckless driving or substance abuse and that kind of thing.

But there's this tendency to be exploratory, to try new things, to push ahead, this also has positive sides. And that's what I think we need to encourage. So coping with the stress that you can't avoid, yes, but also breaking out of yourself and figuring out how do you create networks and alliances to address the upstream problems is something that I think is also a very valuable. We don't have as much evidence of that as we might like to have, but I think the evidence is trending in that direction.

Mai Tran:  Yeah, I really appreciate your perspective on trying to address the issue at the roots instead of shifting blame on other miscellaneous issues that may or may not contribute to the problems.

Daniel Keating:  Right.

Let me just mention, I do think on the social media side, let me just be clear. I think we do need to change how we're approaching social media. It's a proprietary, obviously, setup, so we don't have, from outside, much influence on it. But to the extent that the algorithms aggravate problems, I think we should be addressing that. I think we just shouldn't be laying it all off on that and ignoring the other big existential problems out there.

Mai Tran:  Yeah, definitely. And I also know that you advocated in your article that psychologists should not, quote, unquote, "stay in their lane" by helping kids with the consequences and ignoring the roots of those existential stressors like you just mentioned. So how would you recommend for professionals in the field to take steps towards addressing the roots of these issues?

Daniel Keating:  So I think there are a couple of ways. One is, in the individual therapeutic relationship, I think creating the space rather than focusing down on what the sort of immediate stimulus was for the problem the individual's experiencing is creating enough space for kids to open up about what it is that's truly worrying them. And that is happening. There are some relatively new therapeutic interventions that focus on climate fears, for example, or other kinds of things. And I think we need to create a space for individuals to be able to do that. And so I think that being more broader in the therapeutic content that we would entertain, I think is potentially a very helpful kind of thing. I think the other thing about not staying in the lane is essentially to say, "Well, my goal," and I'm working very hard at it as a therapist, "is to get as many kids out of that downstream before they go over the falls as I can." And that occupies me. That's what I'm doing.

And I think in many ways, that's great, but I think to not recognize what might be going on upstream and how do we try to deal with that because we are encroaching on other disciplines, we're encroaching on sociology or politics or economics or whatever, we should not be intimidated by that. We are, or claim to be, the experts in behavior and things that cause problems for individuals in their life. Well, let's look at that, right? Let's not be put to the sidelines when the sociologists get ahold of it. And I have lots of very good sociologist colleagues and whatnot. So it's not a matter of individuals, it's a matter of who owns what part of the problem. And our Canadian Institute for Advanced Research was designed specifically to overcome that so that we would have force and interdisciplinary dialogue across these many different dimensions and bring all of that expertise to bear in an integrated fashion.

So I think it's basically, it has an impact on the therapeutic relationship, but it also says we shouldn't just stay in our silos that even if we're doing great work in what we're doing, I think being aware of the fact that the problem is bigger than that and trying to speak to it when we can in whatever way we are capable of or comfortable with, I think is, er, not comfortable with, we should be uncomfortable, but that we should embrace that discomfort and deal with those and try to deal with those kinds of issues.

Another is I don't think we're ever going to be addressing successfully the issue of how racism affects youth in this country without being discomforted, right? It's not just an easygoing, "Oh, okay. Everything's rosy now." No, it's not. We need to figure out what's the impact of the legacy and how do we deal with it? And all of those problems that we're talking about have long legacies. I think we need to understand why and try to figure out how to address those as well and in concert with others who do different perspectives on the problem.

Mai Tran:  Yeah, I definitely hope that we'll reach that point in the future soon. And you also just mentioned briefly that you've done research on adolescent risk-taking and risk-taking behaviors. And I also read in your recent review article, "Cognition in Adolescents and Transition into Adulthood", you also discussed the paradox of development versus the high mortality rates in adolescents. Can you explain why this may be the case and what efforts have been done to alleviate this problem?

Daniel Keating:  Sure. Well, there are a number of different angles, different angles to it. I think that one of the things that we need to understand is that when it comes to health risk behavior, the big reason we're interested in it, of course, is not just the scientific part of it, but it is in the impact on everyday lives. And so we know that the rate of morbidity, significant illness, injury, and mortality is way higher than it should be based on how physiologically sound that period of life is. So in many ways, it's a pinnacle of physiological health. So that population particularly, so let's say in the second decade of life, is one where individuals have managed to get through exposures to all sorts of childhood illnesses and exposures and whatnot and have arrived at adolescence.

And we also know that in a variety of ways, different things begin to accumulate. So by the third decade and fourth decade and beyond of life, those things start to manifest. So it should be the healthiest period of time, but we know that the levels of morbidity and mortality are much higher than, in a sense, should be just based on the physiological aspects of that age group. The reason for that is what we've come to call behavioral misadventure, in one way or the other, that individuals are engaging behaviors that have a high risk for mortality or morbidity, and that we need to think about how we might... We want to understand the basis of it more. And we want to figure out how that helps inform our approach to trying to mitigate this problem.

Now, we do have some very good examples. There are ways of modifying population behavior in this age group. One of the best documented is in terms of graduated driver licensing programs, where most states now have a period of time where you gradually get to the point of being able to operate a motor vehicle under any circumstances and includes things like not having unrelated gears in the car or minors in the car, maybe some restrictions on nighttime driving or highway driving or other kinds of things.

There's been very, very good essentially econometric studies of that showing that over the last several decades that the rate of mortality attributable to teen driving has dropped in the 40% to 50% range. So it's not impossible. We can do that. Similar things, not just specifically aimed at teens, but in the population or the society as a whole are issues around smoking essentially by changing the attitude about smoking, right?

Now, I know a lot of youth are into vaping and so forth, but certainly the smoking rate has gone down dramatically. So the point here is that we can identify, or at least in some areas, we have been successful in identifying ways to mitigate that risk for adolescents. The big areas that remain in terms really of morbidity rather than mortality are things like substance use that can turn into substance of abuse or substance use disorders of one kind or another.

The unprotected sexual activity is another one that's a significant contributor to morbidity to various sexually transmitted diseases and infections. And part of that is we seem to be going in the wrong direction, or at least in some places. So there are state by state changes or differences in how sex education is handled in schools. So if we just look at that, there have been studies where we've looked at many different influences in terms of sex education and so forth. And if you put it on a continuum from, "The only thing we're going to talk about is abstinence, that's it. Just don't do it and therefore it will reduce it." So if everyone followed that, yes, that would reduce it, but it's not realistic. That is not how the world works, how human bodies work. So there's that end. And then the other end is a very comprehensive sex education with lots of information and even with community support to get easy and non-embarrassing access to condoms and so forth and so on.

So if we look at the state differences and what's taught in schools, which is not a massive influence, but it's a significant influence, the rates are dramatically different in the sense that the abstinence-only sex education leads to higher levels of unwanted teen pregnancies, higher levels of sexually transmitted diseases and infections, and a whole host of the attendant problems that go along with that. So there's an example of one where we kind of know the evidence is real clear what we should be doing. There's then political and sort of, for some individuals, moral opposition to that. But we definitely know that we have a massively positive impact on that health risk if we just said, "Comprehensive education is what we're going to always do and community support for safe sex."

Mai Tran:  Yeah, I can recognize that that's definitely important, especially education-changing policies and community support. And so finally, would you like to share any additional messages or advice to our audience today?

Daniel Keating:  Well, I think we've covered a lot of the territory. I think I would sum up by saying I would encourage folks on either side of the therapeutic relationship become more aware that it's not just an issue in your mind. If you're having problems, it's not just a problem in your mind, that it is rooted also in the body. We use the term biological embeddings going back a few decades now. And it really does, it gets embedded in your body. And so you need to think about how at both ends of that relationship, to what extent are those contributing factors? How are they operating? And what kinds of things do you want to do? So for example, I think that a shift towards more trauma-informed practices, a shift towards focusing on the key role of relational health as an adjunct to a specific mental health kind of thing is where we need to be going.

I think that we need to have a broader view and a more interdisciplinary view that brings together the biological, the psychological, and the social. And those directions I think will necessarily point us toward looking at the bigger picture that we need to think about changing if we want to create a more less stress inducing world, less of a stress epidemic. And by we, I mean encouraging youth to become involved in that. They're already more involved in many ways than middle-aged and older adults. But I think that encouraging that youthful effort to change things, I think, is really important.

It can be overwhelming and so just ignoring it, in a sense, in some ways is coping, but it's not the best kind of coping, it's a kind of an avoidance coping. And that it also then can have a very positive impact on the individual's sense of efficacy and self and meaningfulness. And we are already seeing that. I think the, that generation, Gen-Z generation in particular is much more involved in these kinds of issues and thinking about these issues. And we need to find ways to support that. I think in many ways the answers will come from that generation if we can support it or at least get out of the way of the kinds of things they might want to be trying to accomplish.

Mai Tran:  Yeah, definitely. Thank you so much. That was really great advice. And if anything, I think we've managed to take away today that to be more aware of environmental risk factors, as you've mentioned extensively about that. So yeah, thank you so much. It was really lovely to finally meet you, and thank you for all the great nuggets of wisdom that you've offered us today. And I will definitely recommend everyone checking out Dr. Keating's research articles and his book "Born Anxious". And finally, thank you everyone for tuning in, and we'll see you all next time.

Atmospheric Researcher Kyle Hilburn on Wildfire Anxiety

An Interview with Atmospheric Researcher, Kyle Hilburn

Kyle Hilburn, M.A. is an atmospheric researcher and research associate at the Cooperative Institute for Research in the Atmosphere at Colorado State University. He specializes in the use of technology to study natural disasters, such as wildfires.

Theresa Nair:  Thank you for joining us today for this installment of The Seattle Psychiatrist Interview Series. I'm Theresa Nair, a research intern at Seattle Anxiety Specialists. I'd like to welcome with us atmospheric researcher, Kyle Hilburn, who is a research associate at the Cooperative Institute for Research in the Atmosphere at Colorado State University. Kyle has a Bachelor's Degree in Atmospheric Science from the University Of North Dakota and a Master's Degree in Meteorology from Florida State University. He was recently a presenter at NASA's Earth Science Applications Week, where he discussed the most recent breakthroughs in the use of NASA satellites to assist emergency responders in tracking the directionality and impact of fires. Thank you so much for joining us today. Before we get started, can you please tell us a little bit more about yourself and what made you interested in studying meteorology?

Kyle Hilburn:  Thank you, Theresa. It's my pleasure to be here with you today. Growing up in Minnesota, I was fascinated by the weather for as long as I can remember. Minnesota has plenty of crazy weather to observe. I will admit that as a young child, I was afraid of loud noises. And so, thunder caused me distress. Some of my childhood interest in lightning was motivated by that. Even though I couldn't control it, I could at least understand it. And that helped me deal with the stress more effectively. I find it incredible that despite millennia of meteorological observations by humans, we are still learning new things about the weather.

For example, when I was in high school, the first photographic documentation of sprites was captured, which are electrical discharges from the tops of thunderstorm clouds. There are undoubtedly many new discoveries still to be made in meteorology. What makes new discoveries possible are advances in technology for observing the atmosphere. And while the public may joke about the accuracy of weather forecasts, there have been steady improvements in weather forecasts over the last 30 years, coming from increased computational power, more sophisticated weather models, and more observations.

It wasn't until I was living in Northern California that I had personal experiences with wildfire, and I realized its important role in the Earth atmosphere system. The growth rate of wildfires rivals that of thunderstorms. The first fire I witnessed relatively up close was the Valley Fire in 2015. It grew from 10,000 acres in the first six hours and 50,000 acres in the first 24 hours. Within two weeks, it had burned 76,000 acres. When fires become large enough and hot enough, they even begin to create their own weather, capturing the physical coupling between fires and the weather is an important theme in my current research.

Theresa Nair:  That's incredible. I mean, I think sometimes we don't realize how quickly fires can spread. Some of the comparisons that you're giving us are amazing. We don't realize that it can spread even faster than a storm.

Many of our audience members are in the Pacific Northwest where wildfires are becoming a growing concern. Since the time you began researching atmospheric behavior, are you noticing any significant changes to wildfires, either in frequency or behavior?

Kyle Hilburn:  Yes. What I've observed and what multiple studies confirm is that wildfires are becoming more frequent, they're growing larger, they're exhibiting more extreme fire behavior, and the fire season has gotten longer. And with population growth in what's called the wildland-urban interface, there are more people with greater exposure to wildfire risks. And it's not just droughts and fires that are becoming more frequent and more extreme, but heavy precipitation seems to be becoming more common as well.

For example, the six 1-in-1,000-year precipitation events that occurred in August in the United States or the recent flooding in Pakistan. This leads to the concept of cascading natural hazards, where heavy precipitation falling after a fire can cause erosion, debris flow, and have impacts on watershed, ecology, and water quality. This recently occurred with tropical storm Kay over Southern California. This cycle of drought, fire and flood is surprisingly common. And the National Weather Service actively monitors for these situations.

Throughout most of my career, the concept of attributing extreme weather events to climate change was considered impossible or at least dubious science. However, with advances in computing power, one can now simulate extreme events with and without the human influence on the climate and thus attribute those events to climate change with some level of confidence. This attribution is being performed almost in real time today.

Theresa Nair:  That's great. Yeah, I think those types of models are important for answering that question of whether we are affecting the atmosphere or not. In your recent presentation for NASA's Earth Science Application Week, you discussed extreme fire behavior and how some fires are large enough to create their own weather. I know you mentioned it a few minutes ago also in this interview. I was wondering if you could give us some examples of that and discussed what types of phenomenon you observe.

Kyle Hilburn:  A primary example is called a “pyrocumulonimbus” cloud, which is a type of thunderstorm that gets its buoyancy from a heat source, such as a wildfire. This type of cloud has only been widely recognized in meteorology in the last 24 years. There are even examples of pyrocumulonimbus clouds that get strong enough to produce lightning that ignite new fires, such as the pyrocumulonimbus cloud created by the Mallard Fire in Texas. Strong winds cause extreme fire behavior as we saw with the Marshall Fire in Boulder, Colorado. This was just a grass fire, but with winds stronger than 100 miles per hour, this fire was able to get out of control and enter an urban area causing so much destruction. People who thought they live far from the wildland-urban interface found out they are more vulnerable to wildfire risk than they thought. The Tubbs Fire in Santa Rosa, California in 2017 burned from Calistoga to Santa Rosa in just three hours’ time, propelled by very strong Diablo winds. Those winds are strongest along ridge-tops and created tendrils of fire that spread down into the valleys and neighborhoods, reaching within half a mile from my house.

The other ingredient in extreme fire behavior is heavy fuel loading, where the term fuel dispassionately refers to trees, shrubs and grasses. Drought, historical forest management practices, and pernicious species have played roles in creating the dead fuel conditions that we find ourselves with today.

In Lauren Johnson's interview on environmental justice, she described Native American forest practices of thinning trees to control fires. That practice is now referred to as a prescribed burn. Although New Mexico, this year, we witnessed a tragedy when a prescribed burn got out of control and became the Calf Canyon/Hermits Peak Fire, the largest in New Mexico history. The goal of my research is to use sophisticated weather models to provide improved decision support tools for prescribed burns and wildfires.

Theresa Nair:  That's really interesting. There's actually a couple follow ups I think I'd like to ask you on that. So with these weather systems that develop in fires, are some of the tools that are being developed able to begin predicting those?

Kyle Hilburn:  Yes, absolutely. We're able to put together all of the physical processes. And a lot of these have been understood for some time, but it's about having the computing power to be able to run these models fast enough to provide the information to people in the field, dealing with the fire.

Theresa Nair:  Okay, and one other thing. You had mentioned the benefits of controlled burns, but then also the risk if it gets out of control. Given the risk of it getting out of control, does it seem like it's better in general to do the controlled burn or is it maybe different in different circumstances?

Kyle Hilburn:  Yeah. I'm not a forest ecologist, but my understanding is that in general, controlled burns are an effective practice for controlling fuel-loads in forests.

Theresa Nair:  Okay, great. In your presentation, I did attend your NASA presentation, you were discussing the most recent applications for using satellites to assist in responding to fires. Could you tell us about the developments in that area and how it differs from previous methods that were used to track the directionality and impact of fires?

Kyle Hilburn:  Satellite remote sensing has been used to detect thermal signatures of active wildfires for over 20 years. Recent developments have improved the spatial and temporal resolution of the observations. For example, currently, the highest resolution satellite sensor with publicly available data has pixels that are 30 acres in area. However, that satellite is on a low Earth orbiting satellite, about 500 miles up, which only observes a given location twice per day. In contrast, geostationary satellites currently provide updates as fast as 30 seconds, but because they're so much farther from Earth, 22,000 miles up, they have pixels that are 1,000 acres in area.

So, part of my research concerns combining these observations from different sensors to get the best of both approaches. Over the coming decades, we will get new sensors and satellites with even finer spatial resolution and faster temporal refresh. These are being designed right now. While small satellite constellations and unmanned aerial vehicles will offer new observing approaches.

The other major development is how we forecast fires. Older models treat fire as an uncoupled system where you have wind blowing over a fire and they use simple assumptions to predict the fire spread based on the wind, but in those models, the fire does not in turn affect the winds. In my research, we're using a fully coupled model. Its name is WRF-SFIRE, which has physical processes in the atmosphere, the fire, and the vegetation coupled together and interact as they do in the real world. This is the only way that you can have fire that creates its own weather. Examples of fire atmosphere interactions include fire-induced winds that can further dry fuels and smoke shading that could inhibit air mixing. Uncoupled models do not represent those types of physical connections. I discussed more technical details about physical processes of WRF-SFIRE in my NASA Earth Science Applications Week presentation, and I've provided the link. (Kyle’s presentation starts 1 hour 32 minutes in.)

Theresa Nair:  That's great. Thank you. And that sounds like incredible research being able to combine all of those different factors and get more accurate predictions about how the fire will actually behave. Are these recent developments in the use of satellite data and the work you've been talking about, are they solely intended for the use of professionals and disaster responders, or is this knowledge that's available to the general public?

Kyle Hilburn:  I would encourage the general public, not to attempt to interpret forecasts from fire models for the same reason your doctor encourages you not to obsess on WebMD. You need to be a trained meteorologist to be able to understand the characteristics of the particular forecast system in order to understand what those forecasts mean. On the other hand, there are websites that provide information on fires, smoke, and weather that are suitable for the public, and I'll provide you links. You should also look for information at your state and local levels to get the information that is most specific to you.

Theresa Nair:  That is great. And we will be linking to all the resources that Kyle's talking about in the transcribed interview below. So if you're watching this interview or if you're on the podcast listening to it, there was a transcription available that we'll have all of the links that he's discussing. Let's talk for a little bit about the relationship between wildfires and mental health. You have extensive experience dealing with wildfires, both from a personal perspective and a professional perspective. When people find out that they may potentially be in the path of a wildfire or that they're in the general proximity of a fire, what steps do you believe would be the most helpful in dealing with the anxiety that might arise from that situation?

Kyle Hilburn:  Well, recognize that a fire doesn't need to be particularly close to cause major impacts on life and various impacts can last days to weeks to months. Even when a fire is 30 miles away, its impacts can make it feel very close. The smoke from a nearby fire can produce a suffocating sensation in a matter of seconds to minutes, which is anxiety provoking. The sky can darken, turning day into night and falling ash can produce an “end of the world” feeling. The smoke can make outdoor exercise impossible, which removes a potential coping mechanism, and it can trigger PTSD in people who have lived through previous fires. Having to leave everything behind at a moment's notice, not knowing what you'll come back to is incredibly stressful. And the aftermath of a fire in an urban setting looks like images from a war.

I've experienced living near fires in Santa Rosa, California, and Fort Collins, Colorado. The Cameron Peak Fire near Fort Collins started in August 2020, and it wasn't 100% contained until December. Fortunately, I was not directly in harm's way with any of these fires, but I still experienced some anxiety. The thing that produced the most anxiety for me was the lack of specific up-to-the-minute information given how fast conditions can change. While messages go out from emergency managers to people currently in evacuation zones, being close to, but not in an evacuation zone can be frustrating because it is hard to get the hyperlocal up-to-date information you want.

So, when confronted by wildfire hazards, one way to deal with the anxiety is practicing mindfulness by which I mean observing your environment and your thoughts about it. Some questions you can ask yourself, is the smoke aloft, or is it near the surface? That can make a big difference in terms of impacts on whether your air quality is healthy or not. How dense is the smoke visually? What is the color of the smoke and how does it affect your perception of the sun or the moon? What does the smoke smell like? Is it spicy and pungent like fresh wildfire smoke, or is the smell more muted? Indicating the smoke has traveled some distance. Is there falling ash? What is the wind direction?

By remaining mindful, you can avoid black and white thinking about the fire. You can observe that its impacts vary from day to day and over the daily cycle. And you can see that like everything, it comes, and it goes. Emergency managers also recommend staying observant in wildfire conditions, which they call maintaining situational awareness. So, staying aware has benefits both to your psychological state and your physical safety.

Another strategy for dealing with the anxiety, turn your focus outwards and practice gratitude for the wildland fire crews responding to the fire incident. Wildland firefighters work extremely hard, and they deserve our appreciation and support. Also, there may be evacuees who need support, but please listen to your local officials and make sure you don't get in the way of their response efforts.

One issue I've experienced during fires is obsession over the latest observations. I found I have to ask myself, is there really any new information? And, when do I expect new information? To keep myself from spiraling into an obsessive-compulsive cycle of refreshing websites repeatedly when fires are nearby. Finally, preparing for wildfire hazards can give you comfort and can make a big difference when the worst does happen. So, I've provided links from Ready.gov, CAL FIRE, and the Red Cross, discussing steps you can take to be prepared.

Theresa Nair:  That's great. And I think we've probably all been in situations where you're repeatedly refreshing that website, trying to get the latest news. Following up on that. You mentioned the importance of not only staying up to date with those resources, but also your own observational skills, keeping an eye out for things, like whether the smoke is closer to the ground or further up, whether there's ash falling from the sky. If somebody notices that their situation is changing, but maybe there aren't any alerts yet saying to evacuate, should they kind of follow their observational signs that they've observed or should they wait to receive specific instructions from authorities?

Kyle Hilburn:  That's a difficult question and it will depend on your own personal feelings about the situation. Things like ash can be transported for many, many miles, and aren't necessarily an indicator that you're in imminent danger. I would definitely recommend that people listen to their state and local authorities and to emergency managers. They will let you know if there is an immediate risk to your safety. But if you're uncomfortable, you can make the choice to leave at any point, if that makes you feel better.

Theresa Nair:  That's true. It never hurts to be more cautious, right? Are there any further developments in tracking or responding to wildfires that you think might be helpful for our audience to know about? And are there specific tools you would recommend for those who are concerned about fires in their area?

Kyle Hilburn:  Yes, I would recommend four websites. First is the AirNow website, which provides information about air quality. In particular, the quantity called PM 2.5, which measures the concentration of particles smaller than 2.5 micrometers, which is a key indicator of the severity of wildfire smoke. And whether it's healthy to be outside. Keep in mind that air quality sensors represent the conditions at a specific point and conditions can vary dramatically with your location. Second is the InciWeb website, which provides information on active wildfire incidents for the United States. You can click on specific incidents and read more information about the current situation and the outlook.

Third is the CIRA SLIDER website, CIRA is where I'm located, which provides access to satellite imagery of fires. When you go to that site, it defaults to the GeoColor product, which is very good for looking at smoke plumes during the daytime, because smoke generally has a darker color than clouds. Under “Product”, you can select fire temperature or natural color fire, and then zoom in on your location. There are color bars at the bottom of the image that tell you what each color means. Under add map, you can add cities, roads, and county boundaries, and other information to see where the fire is located. Keep in mind that clouds and even heavy smoke can obscure the heat signatures from fires. And finally, the National Weather Service at weather.gov is an excellent resource for the official weather forecast coming from human experts with local knowledge and to learn whether there are any watches or warnings for your area.

Theresa Nair:  This is some great recommendations. Thank you. And once again, for our audience, we will provide links for all of those in the description. So if you didn't quite catch that, you can just look at that on the transcript and they'll be there. As an atmospheric researcher who specializes in creating weather prediction models, do you have any other parting words of advice or anything else you'd like to share with our listeners?

Kyle Hilburn:  Well, nature is very restorative for the soul. Florence Williams described nature therapy, such as forest bathing in her interview. And so it is extremely distressing to see nature burning down, but we must remember that fire exists as part of a natural duality between creation and destruction. There are artists such as Erika Osborne, who are exploring this duality and human's relationships with fire. But the increasing rate of changes in our environment is very distressing and climate change anxiety is real. And so, I've provided a link discussing that. Thank you again, Theresa, for this opportunity to discuss managing wildfire anxiety.

Theresa Nair:  Thank you so much for speaking with me today and taking the time to participate in our interview series.
