Episode Date: September 18, 2025

Compared to most of our evolutionary history we have never been richer, safer, or lived longer lives. Yet, despite that, more of us are struggling with our health than ever before. What’s going on? Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests. Today’s clip is from episode 381 of the podcast with Swedish psychiatrist, globally renowned speaker, and best-selling author Dr Anders Hansen. Anders believes we can start to understand the struggles of modern life by looking to the brain, where our emotions are created. In this clip, he offers a powerful reframe for understanding anxiety, and some simple, practical tools to help. Anders is someone who really wants all of us to learn how exactly our brains are wired –  so we can more easily understand ourselves and our daily behaviours.

Today's clip is from episode 381 of the podcast with Sweden, psychiatrist and best-selling author, Dr. Anders Hansen.

Anders believes that we can start to understand the struggles of modern life by looking to the brain where our emotions are created. In this clip, he offers a powerful reframe for understanding anxiety and some simple practical tools to help. As I think about your work, a central philosophy I would say, I would say, seems to be this idea that we've got it pretty good as humans these days, yet at the same time, many of us are struggling. From your perspective, what's going on?

Well, this is something that I have thought of my entire life. We have never had it so good as we have today. We've never been so rich. We've never lived so long. We've never been so healthy. But still, so many seem to be struggling with their mental health. And in Sweden, one in eight adults are on antidepressant medication. And I have realized as a psychiatrist that if you really want to understand this,

you have to start from the brain because that's where your emotions are created. And I think the most important thing I never learned in med school was that the brain did not evolve for intelligence, it did not evolve for creativity, it did not evolve to make us happy, but it evolved to help us survive and reproduce. The primary goal of the brain is not to make a symphony, it's to take you to tomorrow alive. And half of all humans have died before they became teenagers during almost our entire history.

And they did not die from cancer or cardiovascular disease, which is what kills us today, but they died from bleeding, infections, murder, dehydration, accidents. And we are the descendants of the ones who did not die from these causes. And that means that we have in us, defense mechanisms that protects us. And one of those defense mechanisms is that we see the world as more dangerous than it actually is.

And to see the world as more dangerous than it is, that's this anxiety. So from this perspective, you realize that it's not strange that there are people who have anxiety. What is strange is that there are people who don't have anxiety. And maybe they should be diagnosed. And I tell my patience that anxiety doesn't show that you're damaged goods. You're not broken. You have a brain that is trying to protect your life. And a strong pair of arms can lift heavy things.

Strong legs can run fast. But a strong brain is not a brain that goes through periods of stress unaffected. It's a brain that wants you to survive at all costs, even if it means seeing the world is dangerous. And by definition, then feeling bad. So I think we have to be aware that we never evolved for happiness. However, there are things in our modern society that makes the world we live in almost depressiveogenic. It's almost difficult to think of a world that creates so much depressions and anxiety as today's world.

And that's exactly why we need to learn more about the brain and look under the hood and see how we really function in order to sort of work around the Achilles heels that are in our brains. There's a really nice quote that you saw one of the chapters with in The Attention Fix. I don't have it to hand now. But it was something like, it's a surprise that more of us are not mentally ill, given how alien our current environments are. Exactly. And I think what you've just said really speaks to that. Exactly.

And the world that we think is so natural with cars and computers and refrigerators and tinder's, whatever, that's actually a very, very strange world for humans. Almost all previous generations have lived as hunter-gatherers or as farmers. So you may be a doctor or a cab driver or a nurse or a teacher, but biologically speaking, we are all hunters and gatherers. That is what we have adapted for. And those instincts that helped us survive in a world of scarcity and a dangerous world. Those instincts don't help us become happy in a world of overabundance. Yeah. I think that's a really nice rephrasing for your patients with anxiety that, actually, there's nothing wrong with you. Your brain is doing what it's meant to do. Exactly. So anxiety is both natural and hell at the same

time. I don't want to downplay how horrible anxiety can be because it devastates lives. It costs lives, but it's important to understand that you are not broken. You're not damaged goods. And this is something that can be fixed by therapy, by exercise, and if it's really bad, by medication. And you cannot get rid of all of your anxiety, but if you just lower it a bit, you will feel a lot better. But I think the perspective on looking at it as an evolutionary defense mechanism, that makes you less afraid of the anxiety itself, because there's something which is basically fear of fear. You're afraid of your anxiety

and you're afraid that you will get anxious in the future and that might cause as much harm as the anxiety in itself, so to speak. You see patients with panic attacks, they start avoiding things to avoid those possible attacks. And I told the patient once that a panic attack is often a sign that your brain is functioning normally. Because if we assume that we are living on the savannah, which 99.9% of all humans did,

and there's a rustle in the wind. Then you could think that, okay, that's probably nothing. And then you don't do anything. If it's just the wind and you run away, what do you lose then? Would you lose 200 calories? That's what your body uses when you run away. If it's a lion, what you lose then?

Well, then you lose 200,000 calories. That's what the lion will get when he eats you. You lose your life. So from a pure calorie perspective, we should not be surprised that the brain is calibrated in a way that it accepts 1,000 false alarms to not miss the one time your life depended on it. So this really gives an understanding that most panic attacks are false alarms that shows that you are functioning normally.

And when I say that to patients, I've had many of them who say, okay, so it's okay to have a panic attack. And when he realized that, in this case it was a he, those attacks came less often. I mean, it's really powerful, Anders. It's really powerful that sort of reframe. Exactly. Because so many patients think they're broken.

They think there's something wrong. Why is my brain doing this? My partner's brain doesn't do this. There's something wrong with me. And so I think you just been able to validate their experience and say, wait a minute, your brain's doing what it's supposed to do. And you are not damaged. But you suffer and we can fix that.

And that's fine. But you should not look at yourself as someone who is broken. That's very important. How you contextualize an experience of anxiety or depression is very, very important of how you will experience it. And also, if you learn the biology of the brain, you realize that feelings are short-term. They will pause, because the goal of feelings is not that we should have a rich inner life. It's to push us against behaviors that helped us survive in our past. and if feelings were not short-term, you know, that we would not, we need to change behaviors all the time.

So a feeling is there, in your view, to help us change our behavior. Exactly. That's what they're there for. That's the only reason. That's the only reason. So in every moment of our lives, the brain takes information from the body and from the surroundings, and it creates a summary of all that. And that summary is a feeling, and it's supposed to tilt you to behave in certain ways. If your energy levels is low, well, that feeling might be hunger to take care of your nutritional need. If your feeling is lonely, it's telling you to take care of your social needs. So feelings are there to help us do the things that help to survive, not the things that helps us survive today,

but the things that help humans survive in our past. And I would like to see, I almost see feelings as whispers from previous generations of humans who have, against all odds, survived. Yeah, there's a beautiful poeticism, sort of philosophy behind what you said about ancestral whispers. But there's also kind of a change to our physiology. We're seeing lots of research, aren't we, about transgenerational trauma being passed on.

Right, yeah. We see in certain families as if, you know, we see this in Northern Ireland. Iraq, all kinds of countries where there's been significant trauma in the recent history. Yeah. We see that the kids or the grandkids, even though they didn't experience it, they didn't directly experience the trauma, they have imprints off that trauma within them. Their stress response is set differently.

So that idea of whispers from the past, I think it works poetically and physiologically. It does. And, you know, you could see this as a smoke detector principle, if you have a smoke detector in your kitchen, it's okay if that smoke detector sometimes alarms when you burn bread, because it has to alarm when there is a fire. So you accept false alarms. And that's the way you should see anxiety.

Most of it is false alarms. If you grow up in a world where there's a lot of danger where no one is really taking care of you, if you have severe traumas in your families, then the brain thinks that I'm going to live in a very, very dangerous world, and the sensitivity of the smoke detector rises even more, not because you are broken,

but because your brain is trying to help you to survive. So the smoke alarm going off is our anxiety, right? So we can either look at the smoke alarm and go, that's irritating, how annoying, I wish I never put it here. So ignore it, see it as a negative, or we could reframe it and go, okay, it's slightly frustrating, but it's a good job that it's working.

You know, I'll be a bit more careful with checking the toast, maybe putting the setting down on my toaster, whatever it might be. You're looking at it's a positive thing. Thank God it's working so that if ever in the middle of the night, it goes off, I know it's going to save our lives. Is that almost how you want your patience to approach anxiety? Yeah, yeah.

Thank God it's working. It's a good thing. Yeah, I think so. And when I hear patients saying things like, okay, so now I get it. The panic attack is just a false alarm that shows I'm functioning normally. I think of a scene in a movie called Wizard of Oz

from the late 30s, I think. And in this scene, the protagonist, Dorothy, is afraid of a really powerful wizard. And in the end of this movie, the curtain where the wizard is behind is withdrawn by Dorothy's dogs. And she sees that it's just a phony. It's just a phony who's pulling levers

and pushing buttons. And the same thing goes for anxiety. When you realize what it is, when you realize what kind of buttons and levers that are being pulled in your brain, it becomes less frightening. And if you go in therapy, a big part of any therapy

is to sort of see yourself at a distance. And that's very, very difficult to do that. It's very difficult to take a helicopter perspective on yourself. But you could use the brain for doing that. You could say it's just my brain who wants me to be afraid and so on. So I think this perspective can be therapeutic. But having said all of this,

we must remember that anxiety is incredibly powerful. If we could just think, you know, trick anxiety away by thinking, think positive things or be happy or choose happiness or anything, then, you know, anxiety would not exist at all. It is extremely powerful because it's going to motivate us to take care of. of danger. So these are very, very, very powerful things and they will not just get easily tricked. So if you suffer from this, you should definitely seek help. There's no point at all in suffering in vain. So I think first step is you're trying to explain to us and your patients

that, look, this is a normal phenomena, okay? Doesn't mean it's easy to deal with. Yes, it can be frustrating. Yes, it can have a massively negative impacts on your life currently, but it's your brain doing what it's supposed to do. Right. So patients are obviously going to feel better when they hear that, oh, I'm not broken. Okay, there's nothing actually properly wrong with me. Now, the next step is, well, what can I do about it? Now, you said one of the goals of therapy is to try and get that helicopter view. And in the happiness cure, you've got a nice little section on anxiety. There's a nice little box-out, two brain tricks to combat anxiety. You talk about breathing and writing things down. I wonder if you could explain how they might help here. Right. Well, first of all,

there's a part of your nervous system called the autonomic nervous system, and that is something that you can't control, and that it takes care of the organs in your body, how they work, and so on. And there's two parts of this autonomic system. One is called the sympathetic system, and then the parasympathetic system. And these two work at the same time. And the parasympathetic system is digestion of food, being calm at ease. The sympathetic system is stress. That's fight or flight. And it's a balance between this system. You go from digestion to fight or flight, back to digestion and so on, so forth. And it turns out that your breathing actually affects these systems. When you inhale, you amp up.

the sympathetic system. So inhaling is fight or flight. Exhaling is digestion, calm. And you could use this by breathing in for four seconds and breathing out for six seconds. It's longer than one feels normal. And by doing so, you pushes the activity in your autonomic nervous system away from fight and flight. And that is very effective. Breathe in four seconds, breathe out six seconds. Repeat that a couple of times, and that's very, very efficient. And another thing that you could do is to put words on what you're experiencing and try to be a bit nuanced, not just saying I feel bad, but try to describe it in a more objective way. In a journal?

In a journal or say it out loud or just think it, but try to explain it and see it from the distance because that activates certain parts in your prefrontal cortex that calms your amygd, An amygdala is a part of the brain that is very active in detecting threats and has been connecting to anxiety. I mean, it's really interesting, isn't it? I think many people don't realize the power of slow, intentional breathing, when your out breath is longer than you're in breath. You are literally changing your biology. You're changing the signals to your brain, right? We understand it.

We've been conditioned by taking a pill that's kind of a big effect. But actually, I think some of us don't realize just a... how powerful, finding a breathing practice that works for you. I mean, my experience has been that, you know, I've been teaching my patients for years, something called a 3-4-5 breath, where you breathe in for 3, you hold for 4, and you breathe out for 5, right? Again, it's similar principle. But I always say to patients, listen, that's one breath.

Anders is talking about the 4-6 breath. Andrew Wilde talks about the 4-7-8 breath. There's box breathing, right? Find a breathing practice that works for you. you that you resonate with. And could you perhaps share some patient stories where, by, they had bad anxiety and actually breathing was massively useful? I've had one guy who said it was incredibly important for him.

And he actually learned it from you in your books, yeah. And he tried a lot of things. And for him it was very important. He said, this one patient case that I never will forget, and that's a guy in his 20. who came up to me at an airport and he said that he read a book I wrote about physical activity and the brain and how a physical activity reduces anxiety and he decided to try running and he had a very very very bad upbringing it was a child soldier so he had severe post-traumatic distress and he had tried everything and nothing had worked and he had started drinking so he had a

developed a severe alcohol problem as well and then he started to run and from running his anxiety was reduced and then he could cut down his alcohol intake and he did not know whether it was the running or the reduced alcohol that in the end was the most important but it said if i had not started to run i could never have cut down my alcohol and he said that he wished that i had written this book 10 years before so exercise is incredibly important for mood regulation and that goes back to the things that we talked earlier that the brain doesn't doesn't create feelings based on sensory input, it creates feeling based on sensory input and the input from your body. So your body's state is incredibly important when the brain

creates your emotional states. And if you exercise, well, then the whole of the body becomes in better shape. And then the brain gets better signals and that increases the chances that it will create positive feelings instead of negative. I think there was a cycle test you referenced and how it can predict depression in a few years, right? Exactly. That's what's done in the UK. And if you were to cycle for six minutes as fast as you can on a cycle, and then squeeze a handle as hard as you can,

do you think that could say anything of your risk of being depressed from now until 2029? No, you wouldn't think so, would you? No, you wouldn't. I wouldn't at least. I would have think that if I become depressed, that would be if someone would get sick in my family or if I lose my job or something. This was studied on more than 100,000 individuals.

They did this cycling test, they squeezed this handle as hard as they could, and they were followed for six years. And it turns out that the ones who were in good shape, they had lower prevalence. There were fewer of them who were depressed after six years. And then one thought, the researchers thought, that maybe this is because they are more healthy in general.

Maybe they eat better. maybe they sleep more, maybe they don't smoke as much. So they excluded all of these factors in the data, and it turned out that exercise was still protective. And then they thought, well, the depression is not just black and white. It's sort of on a spectrum. You could have a mild depression, you could have a severe depression, but no matter where they put this cut off of what is a depression

and what isn't exercise protected against it. So it's incredibly important that we move. We will not get immune to depressions, but we lower the risk of it. And I say to my patients who have had several depressions and who really, really want to avoid a new one, most of them want to continue having antidepressant medication because they want to be protected against a new depression.

And to them I say that the most important thing, probably even more important than continuing with medication, is that they exercise to avoid a new depression. Yeah, it's absolutely incredible. And you've outlined so much research on exercise. I'd like to think anyone reading your books is going to be convinced if they're not already that exercise, daily exercise, daily movement, whatever you want to call it, is an absolute must. It's not really an optional extra. It's who we are.

My aim with these books has been to present knowledge in a way that everyone can relate to and they have to make, they decide for themselves, but they can make that decision on a level they are more informed. Yeah. What I really remind myself of every day and what I remind my patients of is that the brain is an organ. And like the other organs,

it has not evolved the way it did by chance. It doesn't show the world as it is. It shows the world as we had to see the world to survive, which was often filled with danger. The brain doesn't show ourselves as we are. It shows ourselves as we have. had to see ourselves to survive.

So the brain is not a passive middle step that you could skip if you want to understand yourself. If you want to understand yourself, and if you want to understand human nature, you should start with the brain. And this is an incredible time to live in because we have for the first time been able to look inside and see what's happening in our brain

when we do certain things. And that means that we are studying the machinery of the soul. For the first time in our species history, We can do that. Some of the discoveries are actually pretty new and interesting. And one of these discoveries is how extremely important exercise is for the brain. And the ones who are to benefit the most are the ones who don't exercise at all. So it's when someone who don't do anything start walking to school or taking the bike to school.

That's where the really big effects come in. I hope you enjoyed that bite-sized clip. Do spread the love by sharing this episode with your friends and family.
