Starting point is 00:00:00 It's the most common beat in Western pop music, and it's also this resonant frequency at which, if you just let people walk, that's what they will go to, and if you get people to tap along to a beat in a lab, that's also the beat that they are most accurate at. Welcome to The One You Feed. Throughout time, great thinkers have recognized the importance of the thoughts we have. Quotes like, garbage in, garbage out, or you are what you think, ring true. And yet, for many of us, our thoughts don't strengthen or empower us. We tend toward negativity, self-pity, jealousy, or fear. We see what we don't have instead of what we do.
Starting point is 00:00:46 We think things that hold us back and dampen our spirit but it's not just about thinking our actions matter it takes conscious consistent and creative effort to make a life worth living this podcast is about how other people keep themselves moving in the right direction how they feed their good wolf. I'm Jason Alexander. And I'm Peter Tilden. And together, our mission on the Really Know Really podcast is to get the true answers to life's baffling questions like why the bathroom door doesn't go all the way to the floor, what's in the museum of failure, and does your dog truly love you? We have the answer. Go to reallyknowreally.com and register to win $500, a guest spot on our podcast, or a limited edition

Our guest on this episode is Caroline Williams, a science journalist and editor. She's a consultant for and regular contributor to New Scientist. Her written work has also appeared in The Guardian, The Boston Globe, BBC Future, and BBC Earth, among others. Today, Caroline and Eric discuss her new book, Move, How the New Science of Body Movement Can Set Your Mind Free. Hi, Caroline. Welcome to the show. Hello. Thank you very much for having me.
Starting point is 00:02:14 I'm excited to talk to you about your book. It's called Move, How the New Science of Body Movement Can Set Your Mind Free. And listeners know I am a big proponent of moving my body primarily in order to make my mind feel better. So we'll get into all that in a little bit. But let's start like we always do with a parable. In the parable, there's a grandparent who's talking with their grandchild and they say, in life, there are two wolves inside of us that are always at battle. One is a good wolf, which represents things like kindness and bravery and love. And the other is a bad wolf, which represents things like greed and hatred and fear. And the grandchild stops and thinks about it for a second and looks up at their grandparents says, well, which one wins? And the grandparent says, the one you feed.
Starting point is 00:03:00 So I'd like to start off by asking you what that parable means to you in your life and in the work that you do. I think it's a really fascinating one because not only is it true in life, but in science, you know, there's a real basis for this. Before I got really into movement, my career, 20 years or so as a science journalist, was looking at the plasticity of the human brain and how it changes. And it really is true that what we do, the way we behave, the way we think gets written into our brains in, you know, physical connections between neurons and in the pathways. And, you know, as you sort of walk these paths through your brain, they become more, um, more worn in, worn in. Yeah. That's the word I'm thinking of indented, but that's not really the word I mean, but yeah, they, they become like, like pass through long
Starting point is 00:03:49 grass and they become better traveled. And so, yeah, it's absolutely true that, that if you choose to be positive and to choose kindness and compassion, that's been shown many times that that can actually change the way your brain works and the way you live your lives. So there really is something solid behind that. And that's sort of the way I like to operate. I guess I'm a bit of a natural skeptic. I want to look for the science, look for, you know, where the evidence lies and absolutely does back that up for sure. So I try to live that way myself. Yeah. I was reflecting earlier today on, you know, I occasionally just somewhat jokingly say myself. Yeah, I was reflecting earlier today on, you know, I occasionally just somewhat jokingly say like, well, I'm just a bag of chemicals,
Starting point is 00:04:34 right? Like, yeah, at the end of the day, we've got neurotransmitters, and we've got hormones, and we've got electrical connections and synapses. And it's just all very physical, you know, it has a very physical element to it. It's chemicals, all that sort of stuff. And yet those things both control how we feel and then also the things that we do can change those chemicals. There's just such an interesting interaction between the two that you would think like, well, if it's all chemicals, then the way to intervene is chemically, but not necessarily. And your book is a big testament to that, that there are ways of changing what's happening inside, not just our body, but our brain through the way we move. Absolutely. I mean, that's one of the things that got me started on this whole thing. I've been so interested for many years in what's happening in the brain and how to, you know, change brain chemistry, how to change the way you think and feel focused on the brain. And then it sort of became obvious to me that thinking of your brain as if it's not attached to the rest of you is kind of weird.
Starting point is 00:05:33 And of course, there's all this pipework that, you know, all the blood flow packed with hormones and all kinds of other stuff, and all the wiring and the electrical activity that's going up and down our nerves. all kinds of other stuff and all the wiring and the electrical activity that's going up and down our nerves that all impacts what happens chemically physically and as a result emotionally and the way that we are able to think so obviously what happens below the neck matters for how we think and feel and going on from that it became quite obvious that things that we do to our bodies can change that chemical environment and change the electrical environment and as has a knock-on effect on everything so so in a way it's liberating because you can then use your body as an extension to to sort of tweak these parameters and change the way that you feel in the way that life feels to you as well your sort
Starting point is 00:06:22 of outlook on the world yeah i always find it funny when people talk about like the brain body connection as if they discovered something radical, like, oh, I mean, obviously, it's, it's always been connected. You know, I'm not quite sure how we got to it's so disconnected. I had a strangely, I'm taking things off topic here, sort of not really. I had a epiphany about a week and a half ago. I was doing loving kindness meditation and it was a guided meditation and the leader of the meditation instructed you to try and notice where in your body you're feeling this thing happen. And I realized where I was feeling it mostly was my face. And I had been discounting the face as part of my body for a long time. Every time I was told, look for where this emotion is in your body. If I noticed
Starting point is 00:07:14 it in my face, I was like, no, that's my head. Where's in my body? Yeah, yeah, yeah. But I had this moment where I was like, a dummy, hey, your face. Your face is part of your body. Is part of your body. It is an emotional center. It's where I happen to feel a lot of things. And that's sort of on topic as far as the brain body connection. No, I mean, it's really relevant because a lot of people struggle to tune in to where these feelings are. So there's this thing called alexithymia, where people aren't able to put names to their emotions. And if you can't do that, then it's really hard to regulate your emotions. So things like meditation and, you know, checking in with your body can be a way of sort of tuning in and going, OK, so I'm feeling this right now.
Starting point is 00:08:05 change what I'm doing with my body or, you know, with my face, which is part of my body, and how that can then have a feedback that will maybe make me feel differently. So yeah, that's really, really relevant. And so that came up quite a lot in my research that being able to tune into your body and know what it needs, and know what your entire body, brain, mind needs is a really important skill. And because, and often if we're so sedentary, we're so disconnected from our body, we're up in our heads all the time that we don't often make that connection. So it's a really important aspect of tuning in to your body. Yeah. So let's start with talking a little bit about what the brain evolved to do. And I'd also like to talk a little bit about what certain people
Starting point is 00:08:46 think the brain is doing, what its role is. Can we talk about those two things real quickly before we move into the specifics of movement? Absolutely, because this is where it all comes back to. So we tend to have this idea that brains are there for thinking and working stuff out. But actually, if you look way back in our evolutionary history, not every organism on the planet has a brain. Even a lot of animals don't have brains. And at some point, evolution had to make a decision whether brains were worth investing in or not. And there's this very well-known neuroscientist called Rodolfo Linas from Colombia. And he pointed out that there's this
Starting point is 00:09:25 creature called the sea squirt. In their adult form, they just look like sort of bagpipes stuck to the bottom of the ocean and they suck in water through one pipe and they blow it out through the other and they don't move. But in their young form, in the larval form, they're sort of like tadpoles. They swim around the ocean and their job in life is to find a place on the ocean to attach and live out the rest of their lives. And when they're in this juvenile stage, they have sort of a very basic brain. And the reason for this is that it needs to coordinate its movements away from things that are harmful and towards rewards. So it's a basic system. What will kill me? What will help me pass on my genes?
Starting point is 00:10:02 And so this basic brain is connected to its basic tail and it swims around when this larva finds the perfect spot it attaches basically by gluing its head to a rock and one of the first things it does is reabsorbs its entire nervous system and it never makes any decisions ever again so lena said well this just goes to show what a brain is for. A brain is for informing your movements in the world so that it can increase your chances of survival by taking you towards things that will keep you alive and taking you away from things that will kill you. And if you're not going to move, then you don't need the brain. And, you know, they're expensive bits of kit. They're high energy and they take a lot to run and so yeah from right early on brains were there to
Starting point is 00:10:46 inform our movements in the world and you can see that everything that's been added on later right up to our you know our clever emotions you know in fact emotion comes from the words in the latin for to move away from something so emotions inform us about what we need to get away from and what we need to get to. So everything else that's come since then has been about informing our movements in the world, which is something that you don't often think about. You think brains, yay us, we've got a cracking brain for thinking very clever thoughts. But at the basis of it, our brains are there to help us move sensibly. Yeah, I love that analogy of the C-score.
Starting point is 00:11:23 It explains a lot about the editor of this podcast, Chris, also, and what has happened to him. I think basically what you said is once they stop moving, they basically just get rid of their brain. They just don't have it anymore. Yeah. Yeah, yeah. It just gets recycled because the energy can be reused for something else. And, you know, I'm not saying that the poor editor, I'm sure he's a lovely man, very clever man. Let's just say he doesn't move much and he's not very smart. I'm just making some connections here. I wouldn't like to comment. But it's true that in humans, especially this use it or lose it nature of our brains became even more sort of tied together in the point of our evolution when we became hunters and gatherers. Because then, you know, our ancestors could maybe sit around in trees munching on fruit
Starting point is 00:12:09 and get away with it and they were absolutely fine. When we started moving further afield and looking for food, we had to evolve to be able to stand on our feet and walk long distances and, you know, forage far and wide and hunt. But we also needed to be able to work together to bring down prey because humans are quite puny, really. You know, we're not very fast. We're not very strong.
Starting point is 00:12:32 We also needed to be able to, you know, communicate, to work together, to remember the way home. There's a lot of cognitive work that goes into being a hunter-gatherer. And so there's this idea that once we started taking this way of life, our physiology tied together, moving around, being active with the health of our brain. And that explains why, you know, we've known for a long time that physical activity prompts the brain to be particularly plastic. It adds more connections, it adds more blood flow, you know, everything works better when you've been active. And the reason for that is because these two things go together. At that point in our
Starting point is 00:13:08 evolution, it stopped being optional to move because if we don't move as much as our evolutionary history says we should, then the brain starts making savings. And over a lifetime, that can be quite significant. So, you know, there is these quite frightening statistics that 13% of Alzheimer's cases can be traced to a sedentary lifestyle. So brain health in general is better with movement. Lots of studies show that. I want to pivot a little bit to mental health now, which is similar but slightly different. You say that poor mental health might be part of the price we pay for a cushy life of sofas and supermarkets. Yeah, I mean, because at the end of the day, we are the only creatures on the planet where movement is optional. You know, we can get food, we can find a mate, we can
Starting point is 00:14:10 entertain ourselves, we can do everything we like from sitting down and just moving our thumbs and fingers a little bit if we want to. So we have to seek it out. And, you know, statistics suggest that by and large, we don't. And also in working life nowadays, even for people who write about movement for a living, spend a lot of time sitting in this very chair and not moving. So we have to seek it out if we're going to do it. And obviously, there's been a real change over the past decades. We move a lot less than even sort of our parents' generation. And we have seen this catastrophic rise in mental ill health and
Starting point is 00:14:47 loneliness and all these other sort of things. And clearly, there's more than one thing going on. I'm not saying, oh, well, that's a straight line between our sedentary lifestyles and mental health. But given that we have got this trend, and we know that movement, exercise, even just going for a walk is really, really important and really good boost for mental health, as is strength training. That's a really, really important one that a lot of people neglect. Being physically stronger has been shown really, really conclusively to help with anxiety and depression and just make people feel more powerful in the world and able to cope. There's a measure psychologists call global self-e self efficacy. And that's just basically a way of saying, I feel like I can handle stuff.
Starting point is 00:15:31 And when people have improved their physical strength through through weight training or body weight training, they do feel more capable. So I think there's a real role to play in becoming more active in particular ways as well that could really improve people's mental health. I'm going to jump backwards a little bit, maybe. I want to talk a little bit about interoception and what it is and how that leads to what certain scientists call a global emotional moment and then link in how movement ties into that. Yeah, so interoception is sort of a little known sense that we have. And it's the sense of the internal state of our body. So rather than thinking of, you know, the brain is the master computer that sort of just sends messages downstream, interoception is about
Starting point is 00:16:17 a crosstalk between the body and the brain. So you think of the brain more as a sort of facilitator that sort of takes all the information that's coming in about, you know, what hormones are in the blood, whether you're hungry, whether you're thirsty, whether you're feeling whether the fight or flight response is kicked in, you know, all these kinds of things that are going on, even down to our heartbeat, you know, the way that we're digesting our food all this information is being passed back and forth brain and body all the time and what we know is that slight differences in the messages that are going from the body these interoceptive messages can really affect mental health and there's this whole body of research now that suggests that some people are more or less
Starting point is 00:17:01 sensitive to their interoceptive signals and that can make you more or less sensitive to their interoceptive signals, and that can make you more or less susceptible to things like depression, anxiety, schizophrenia, all kinds of mental health issues. And it's involved in things like autism and ADHD and all these kinds of things. The global emotional moment is basically your brain's picture, you know, taking in all this information. brain's picture, you know, taking in all this information. So there's a part of the brain called the insula that takes all this information and puts it all together and comes up with a sense of how I feel now. And the I bit of it, the me, the sense of self comes from these bodily signals and putting them all together brings this global emotional moment. And so it stands to reason that if you do anything to change these messages, then that global emotional moment will change. And so I think tweaking the dials is something that could
Starting point is 00:17:51 really benefit people by, as I said earlier, tuning in, doing something to change the messages, and that will change the way you feel in the moment, but also in the long term. So the strength stuff is really interesting because the idea behind why strength might make you feel more capable is that you're upgrading these interceptive signals from your muscles and from your bones that are just maybe giving this unconscious sense that I'm strong. It's fine. You can stand down the anxiety because if anything happens, I can handle it. And maybe that's what explains the very strong link between increased strength and feeling more powerful. Yeah, I think this is a really important topic, this idea of interoception and signals coming from the body that we aggregate them generally and it creates this global emotional moment. Because I've spent a lot of time thinking about do thoughts cause emotions?
Starting point is 00:18:41 Do emotions cause thought? And, you know, it's a big debate a lot in psychology. And I think the answer is as near as I can tell, it's a bidirectional relationship. I almost more and more I'm starting to go, are they even different or they co-arise? Yeah. The thing that first got me really going, wait, I'm not sure that thought always causes emotion is because I was able to notice very clearly some days I would wake up and I would just immediately feel a certain way before I'd had any thought. And then it felt like every thought got filtered through that feeling. And that's what you're describing. That global emotional moment
Starting point is 00:19:19 is sort of like the weather that's inside our brain. And then our thoughts can't help but to some degree be influenced by that weather. Yeah. So one way that I heard it described that I really like is background music. It's sort of like the background music to our lives. So like when you're watching a film, you know, you're watching a horror film and you can't quite work out why you're feeling on edge. But it's the background movement that's kind of making you nervous yeah and yeah by changing these interceptive messages you can change the background music on your life so that rather than feeling like oh god you know you know you can actually do something that makes everything feel a bit more positive and feel a bit
Starting point is 00:20:00 more possible that's what the power of movement doing in the moment and long term, that if you can change those messages, then in general, your background movements, your life will be better, and we'll be happier, we'll be more capable. Yeah, we interviewed, it's been years ago, a woman named Michelle Seeger, and she had done some writing on movement and how it makes us feel. And she said something, I won't get it exactly right, but it stuck with me all these years, all these interviews, which is like, if your body doesn't feel good, your brain, your mental state, you're going to feel like shit. The flavor of that may depend on your particular neuroses and conditioning, but if the body is out of whack, it's going to influence it. And I think that's what we're saying. And with interoception, what you're saying is when we move, it helps the body be in a better place. And thus the messages that we're getting in the brain are better changing that background music to something that is more enjoyable.
Starting point is 00:20:55 Yeah. And in sort of ways that you can't even put your finger on. Yeah. So just like, you know, when you're feeling down and depressed and miserable, sometimes you don't know why. Yeah. You know, but if you can improve the background messages then you can just feel okay yeah um for reasons that you don't have to dwell on you just feel okay and you're bumbling along through your life and everything is groovy
Starting point is 00:21:15 so yeah that there's a lot you can do and i think it was not really a surprise to me when i started thinking of movement this way it was sort of a penny dropping. Like, well, of course, I never feel more like myself than when I'm halfway through a yoga class or, you know, on a long walk or, you know, kayaking or just doing something active. I know who I am. I feel good. I know what I'm capable of and everything's great. If I'm slumped down, not moved, I mean, I had to isolate for 10 days when I had COVID. Oh my goodness. I mean, I was the worst version of myself ever. I mean, I had to isolate for 10 days when I had COVID. Oh my goodness. I mean, I was the worst version of myself ever. I mean, in theory, I could have written several books in that time, but well, not really, but you know, I could have done a lot of work, but I was so miserable. I was so lethargic, you know, and I think if anyone who is quite active sort of knows
Starting point is 00:21:59 this in themselves, but it's kind of interesting to put the science and the philosophy behind it and say, yeah, for me, that means there are good reasons to seek it out and to not be lazy, even though it's comfortable. Yeah, this speaks to two of the mantras that I use on the show the most. One is depression hates a moving target. It has always been true in my case. And then the other is sometimes you can't think your way into right action. You have to act your way into right thinking. Right.
Starting point is 00:22:23 you can't think your way into right action. You have to act your way into right thinking, right? And that speaks to the fact that the action, in this case, we're talking about movement, the actual physical movement changes the way we think versus just sitting there trying to feel better and think better. Sometimes it just doesn't work. So my previous book, Override, or My Plastic Brain in the US, was all about trying to think, you know, trying to do something to my brain to change my brain's workings, you know, to make me less anxious, to make me more creative, to, you know, to change various things. And especially when it came to anxiety, the thing that bugged me about it is that most of the treatments revolve around thinking your way out of it, thinking, I feel anxious about this. Logically, that shouldn't be the case.
Starting point is 00:23:04 I can tell myself that I don't need to be anxious about this. Logically, that shouldn't be the case. I can tell myself that I don't need to be anxious about this. And that's not how it works when you're living it. Yes. You can't think your way out of it. Of course, there's the issue with things like depression, that getting moving in the first place. Yes. Is a problem. And a really interesting research that I found was one of the first signs that an antidepressant medication is starting to work is that people
Starting point is 00:23:25 have an increase in voluntary movement. So people want to move more. And then that starts off the, you know, the nice cycle of upward movement, hopefully. But yeah, I think it's absolutely true that if you can get over that barrier and get yourself moving, then you're often running. And that's been shown time and again. I wish i had an easy answer to how to get off the chair in the first place but i know that is a cruel irony of really severe depression is that yeah one of the things that might help you a lot is one of the things that's very hardest to do which is you know why really learning to start small can be helpful like how you know what's the what's the littlest thing I can do? With physical activity, the thing I've noticed a lot is that, let's say I'm thinking, all right, I need
Starting point is 00:24:11 to do a 45 minute bike ride. And my brain thinks about that. And it thinks about the amount of energy a 45 minute bike ride takes. It knows what it takes. It's done it. It's like, okay, that's a lot of energy. And it compares it to what it feels currently. And it's like, that's not doable. Yeah. Which is why the strategy of like, all right, Eric, just put on your bike shoes, get in the other room works. Yeah. This is my own sort of interpretation of what I think is happening in my brain. But my brain is going, oh, bike shoes, you know, one unit of energy. You've got one unit of energy, I can do it. That way, until at some juncture, the energy starts to generate from the workout itself and propels me. So that strategy has saved me more times than I can count.
Starting point is 00:24:58 I've been quite slack on the getting out of bed and doing early morning yoga of late, but I was regularly getting up at six and going sort of half an hour down the road and doing an hour and a half of yoga in the morning. And the way I managed to do that was when I woke up and groaned, because getting out of bed is my least favorite thing in the world, I used to just say to myself, tuck and roll. I would just tuck, roll out of bed and go. Tuck and roll, that's good.
Starting point is 00:25:21 Yeah, tuck and roll hasn't worked for me that well recently. But now I do go out on a lot of bike rides with friends. And, yeah, having them appear at the door and say, why aren't you ready? Tends to spur me into action. So, yeah, it's either pressure from outside or some sneaky strategy can be the way. But, you know, one of the people I met during the research for the book was Marcus Scottney, who's an ultra marathon runner who has suffered with depression his entire adult life. Scottney, who's an ultra marathon runner who has suffered with depression his entire adult life. And even he said to me, I just couldn't understand how can I push myself to run an ultra marathon over several days when my feet are bleeding and I'm absolutely exhausted. And yet,
Starting point is 00:25:57 sometimes I can't get myself out of this depression. You know, I've clearly got the strength of mind to do that. Why can't I do that? So even the best movers struggle with it. I'm Jason Alexander. And I'm Peter Tilden. And together on the Really No Really podcast, our mission is to get the true answers to life's baffling questions like... Why they refuse to make the bathroom door go all the way to the floor. We got the answer.

And you can find it on the iHeartRadio app, on Apple Podcasts, or wherever you get your podcasts. Let's move into talking about some specific types of movement. So one of the things I loved about this book is you set it up as globally movement is really good for us.
Starting point is 00:27:51 But then we kind of go through different types of movement and some of the specific benefits. So let's talk a little bit about walking. What did you find most fascinating about the research you did into walking? For most people, it's such an accessible thing that most people can do. I was surprised at how it's such a multi-use tool. So there's the research into creativity. So, you know, just in a brain focused sense, we know that when activity is turned down in the frontal parts of the brain, which is the bit behind the forehead, that we tend to think less in straight lines. You know, that's the part of the brain that kind of keeps us tethered and keeps pulling us back and says, don't be daft, that won't work. And, you know, keeps us with the
Starting point is 00:28:32 obvious options. And we know that, you know, artificially turning down activity in that brain region makes you more creative. We also know that walking does something very similar to this brain region. And so if you go out at a sort of a moderate pace where you're not having to expend much effort, you're just sort of meandering and that tends to turn down this thinking bit of the brain and the brain goes wide and that's been shown to increase creativity. So we have this idea, I think, in modern society that if we need to work and come up with something new, we need to sit at our desks and bang our head against the desk until we come up with a great idea but i mean that's completely not the way we should be doing it and science says go for a walk and go for a wander and i think we need to
Starting point is 00:29:12 sort of you know rebrand working is something that can be done on the move so that's one way of using walking that's that's really really easy and it sort of spills over for about 20 experiments like for about 20 minutes after you come back for the walk. So you can have a brainstorming meeting, go out for a wander, come back, and you should have better ideas. Another way is the faster, more brisk walk. So there was some really intriguing research I came across. This great guy called Dick Green, who started off looking at pipeworks in oil fields and then turned his attention to pipework of the human body and the blood vessels. And I guess it's sort of the same thing, really. And he found that we essentially have these pressure sensors on our feet.
Starting point is 00:29:49 And when we're putting weight on our feet and walking, that sort of sets up turbulence in the blood vessels, which adds up to a boost of blood to the brain. And I guess that's, in a way, that's not that surprising. That's why you feel a bit more alert when you've been up on your feet and moving. But he found this sweet spot where our footsteps are at 120 steps per minute and our heart rate is also at 120 beats per minute. And our heart rate and our footsteps synchronize. And this gives you the best boost of blood to the brain, something like 20%. The even cooler thing about this is that 120
Starting point is 00:30:25 beats per minute, it's the most common beat in Western pop music. And it's also sort of this resonant frequency at which if you just let people walk, that's what they will go to. And if you get people to tap along to a beat in a lab, that's also the beat that they are most accurate at. There's something magic about this 120 beats per minute. The good thing about it being common in music, you can Google any of your favorite genre of movement and 120 beats per minute, and you can find the music that you can step in time to and just get going.
Starting point is 00:30:55 And it seems to make, you know, when your heartbeat gets into synchrony, that's when you get a boost. So, you know, he doesn't have firm data that this is what happens and your brain works better. But what he says is it could really account for this feeling of well-being we get when we're out and moving briskly. So if you want to not necessarily think broad thoughts, you want to get out there and after a period of sitting and getting lethargic, you want to
Starting point is 00:31:21 gee yourself up again and get back in the room, then going for a very quick stomp is a really effective way of doing that. At 120 beats per minute. I love that. Yes. There's another idea in that section on walking that says our bones are in constant conversation with our brains. What does that mean? That's an intriguing statement. I know because we tend to think of our bones as being these sort of dry, dusty sticks that hold us up and that they don't do very much. But in reality, they are a living tissue that's constantly being built up if we stress them by putting weight on them, or they get broken down if we're not putting weight on them and, you know, we start to lose bone density. And when we're actually building up bone, there is a hormone released from that bone that goes into the blood. And it doesn't actually have anything to do with the bone building process.
Starting point is 00:32:12 What it seems to do is travel to the brain. It sort of docks onto the part of the brain called the hippocampus, which is important for memory. And it's been shown in experiments to improve memory and just make the brain function better. It seems to have an effect on anxiety as well. So this is all sort of connected again. So when we're putting weight on our bones, we're strengthening our bones, we're making our body more able to move us around away from danger towards rewards. It's also giving a boost to our brain to learn better and to retain information better. To me, that was a really surprising one. You know,
Starting point is 00:32:45 you think of hormones, you think of glands, you know, you think of, you know, all different kinds of things. You don't think of your bones as secreting hormones that help your brain to work properly, but they absolutely do. So this is really interesting research. So we're now looking into it in terms of cognitive aging, because the bad news is that when you get to about middle age, because the bad news is that when you get to about middle age, the production of this hormone, osteocalcin, drops off. And so you have to do a lot of weight-bearing exercise to keep that going, which is something that's very important, especially for women in middle age when estrogen starts to drop off. It needs to happen anyway, but this is another reason to keep your bones healthy and to do that weight-bearing exercise. Not only will you
Starting point is 00:33:23 feel better, your brain might work better as well so yeah that was a real surprising one for me and by weight-bearing exercise in this case we mean walking walking is a weight-bearing exercise yeah I mean anything that's holding up your own weight against gravity and moving counts as weight-bearing exercise so we don't know yet it's too early in the research to know whether you know adding ankle weights while you go for a walk you know gives you you know more osteocalcin or whatever. So any form of weight bearing exercise, we don't know whether more is better, but I would probably suspect that more is better,
Starting point is 00:33:53 but I don't have any data to back that up. So don't quote me on it, but yeah, I mean, what's the worst that can happen? You can move better, get stronger. All good things come from that. Yeah. It makes me feel like I need to walk more. My primary cardio exercise is now this Peloton bike, which I love and has been great for my amount of time I spend doing cardio and a lot of different things. But it is not, as you say, a weight-bearing exercise in the same way. And the other thing about it is it's not outdoors. outdoors. Yeah. And then, you know, there's other stuff. This isn't in the book, but I have written about balance and researchers who were working on, you know, our balance is nothing that declines with age and being on a stationary bike is great for cardio. But if you're on an actual bike, you're having to fight gravity and you're having to keep yourself upright. So being on a stationary bike or a treadmill doesn't tax your brain in quite the same way as being out in the real world and dodging obstacles and having to look over your shoulder and that kind of thing. Yeah. Yeah. You write that depressed people walk
Starting point is 00:34:48 differently than non-depressed people, more slowly, hardly moving their arms and assuming a slump posture with their eyes to the floor. I was really struck by that last part, the eyes to the floor thing. I've been doing something the last, I don't know, month or so. It's called the Alexander technique. I don't know if you've ever come across it. Yeah, I don't know much about it, but I have heard of it. I don't either still after a month. But part of what the Alexander Technique is trying to do is to get you to recognize sort of your habitual patterns of use, your body being, you know, the main one, and undo those by sort of letting them go. But one of the things that my Alexander technique instructor has pointed out to me is that my natural use is
Starting point is 00:35:33 head down slightly looking more towards the floor. That's sort of where I naturally orient. And as I've started to pay closer attention to that, I'm like, yeah, even when walking, I'm kind of a little bit of that head down. So I was struck by that eyes to the floor piece. You actually talk about it also in the section about core exercises also that this is another thing. But I was really struck by that because like I said, it was just pointed out to me this week that I do that. Yeah, I do it too. I catch myself all the time and I have to remind myself, look up, look out at the world and head up, posture matters. Yeah, and that's another thing, the core research is really interesting. And the effects of just changing the way, again, it's the messages that your body's sending about how you feel.
Starting point is 00:36:21 And we know that slumped posture you know everything from you know a defeated chimpanzee will will sit and slump down and sort of broadcast the message uh leave me alone i give up um that sort of come through to us as well but the benefit of being a human is we can reflect on that and we can change it and then we feed back that you know the body then tells the brain okay you're setting up straight you must be feeling better. And there's some really interesting research into what causes that. And I don't know whether your listeners will probably know about Amy Cuddy's power posing research, that she got a really hard time because she then linked changes in posture to changes in hormones in the body that hasn't been backed up by other research. But the fact of posture affecting the way you feel has been backed up many, many, many times.
Starting point is 00:37:08 So we're just still looking for the killer mechanism that explains exactly. So, I mean, there's one potential one that I go in the book, which is really interesting to me, for the same reasons I was talking about, like thinking your way out of stress. Because there are links that have emerged between like neural links literally wiring pathways between the adrenal glands that pump out stress hormones and the parts of the brain that control movement so it's like this strip of brain tissue across sort of where your headphones go across the top of your head and these wires from the adrenal glands end up in the part of the brain that controls voluntary
Starting point is 00:37:46 movement of the core. So the trunk muscles, the ones that keep you upright or not upright. And it's really interesting. There's something to do with movement. There's something to do with this movement of this midsection of your body and the posture that you keep that's linked in with the stress system. And so to me, that suggests that rather than having to think your way out of a stressful situation, there's something you can do with your body you can strengthen that core you can change your posture you can take control and tell yourself via your body that everything's all right and that you can stand down this stress response so to me i mean i'm hoping that there's going to be more research in this area you know they're working very hard on it that will show
Starting point is 00:38:22 us exactly how to do that but but this link the given that we know that posture makes you feel better and these links are there it would suggest quite strongly that having strong core a good posture can you know really effectively change the way you feel and how you deal with stress in that section on core you talk about that neural pathway but you also say that it's the area of the body where most of our internal organs are found, which means it's the point of origin for a lot of our interoceptive messages that we were talking about earlier. And so that that area being, you know, in good shape, so to speak, might improve the way we feel also in that way, because the interoceptive messages.
Starting point is 00:39:06 Yeah. And then there's this also idea that, you know, this area of the body, because the organs are there, so these, you know, the messages from the heart, from the lungs, you know, everything is coming from the stomach, everything's coming from this region, that maybe this sort of is a focal point. So there's one neuroscientist who thinks that this is why we have this sense of being in our bodies and looking out of it because these interoceptive messages are in our sort of core of our body so there's something special about our trunk because that's where we are in in some ways um so i think that's a really interesting viewpoint you know a lot of people think oh the me is in my head behind my eyes. Actually, maybe a lot of me is in my midsection of my body where all the important stuff,
Starting point is 00:39:49 well, the brain's important too, but the other important stuff is. There's a lot of other important stuff, yes. Let's hit strength training a little bit more. You hit on it to some degree, but there have been studies that compare different forms of exercise or they show and you you write about that strength training is faster and more powerful effects on self-esteem yeah yeah so this was one of the things that really surprised me because you know everyone knows cardio makes you feel good gets the blood pumping endorphins blah blah but studies have shown that strength training
Starting point is 00:40:22 alone regardless of whether you're doing cardio or other forms of exercise, do lift mood. They help you feel more powerful and more capable in your life. And that's one area that I think is quite easy to neglect. You can go out and go for a run. You can go and cycle or swim or whatever. But actually focusing on your physical strength is something that's easy to miss. And it's really important, especially in young people, because there's evidence that young people are less strong than they were 10 years ago, as are a lot of adults as well. And that maybe that's
Starting point is 00:40:57 feeding into some of the anxiety issues that we're seeing in young people and, you know, that they're feeling really under pressure, unable to cope. So, you know, that they're feeling really under pressure, unable to cope. So, you know, giving them strength at an early age can hopefully give them some tools to take forward into their adult life and feel confident and feel that they matter and that they've got something to offer the world. So it's something that we're missing out on and I think we could definitely do better with. Yeah, the studies that you referenced were a little bit staggering, depending on how you measure strength. We're talking about a 20 to 30% decrease in youth since the year 2000. That is not very long ago. I know. It's kind of terrifying, really. You know, I have a 12-year-old and I think, oof, luckily he's a fidget like I am, so he's always on the move and doing stuff. But yeah, I mean, it's still very easy to go through school and come out the other end
Starting point is 00:41:48 and feel that physical activity and movement is not for you and you're not a sporty kid and you're not very strong. And that's really got to change. It's not helpful because those kids then leave and then they're not the ones who seek out movement in adulthood and when you really have to seek it out because you haven't got the time anymore like you did when you were a kid yeah so i think we need to to do better for children in schools you know we're cutting down on pe time we're cutting down on break time recess time and kids aren't playing outside like they used to they're not walking to school like they used to um yeah yeah there's all kinds of things that they're not doing that
Starting point is 00:42:24 are playing into this. And I think really needs to be urgently looked at. Yeah. And as you said, strength training is one of the easiest areas to let go. Like I mentioned, the cardio bike that I have sitting next to me here, I just use it a lot. And I love it. Strength training has proven to be more challenging for me to do consistently. What's actually worked for me is I found I've really needed a trainer, someone virtually. And luckily, I'm in a position where I'm able to afford that from time to time. But yeah, it's a harder thing for me to motivate myself to do and to know like, what's the right level? How much should I be doing?
Starting point is 00:43:02 There's more nuance to it yeah it's not obvious is it going for a run you know when you're breathless and you know you can go a bit further than you did last time it's a bit tricky but I mean it doesn't always have to be using weights and in a gym or you know doing anything like that we can build stuff into our lives so I try and make an effort now so you can't see from the screen but I'm actually really small I'm four foot eleven I'm quite slight if I'm out somewhere and someone say if i'm carrying something and someone says can i help you with that i always say no no i'm i'm fine you know i make an effort to to carry things because that's really important that you can use what strength you have and keep it going so it can
Starting point is 00:43:38 be as simple as choosing to carry your shopping home choosing to lift and carry stuff rather than putting it in a shopping trolley you know yeah We can build these things into our lives and after a while they become habits. So that's another way of doing it for people who aren't necessarily into getting into Lycra and lifting weights. Because a lot of people don't feel confident doing that. I'm not in Lycra. I'm not wearing Lycra. I'm not. I'm telling you. No. Chris, on the other hand, Chris is, no, poor Chris. He's loving the Lycra.
Starting point is 00:44:10 Well, he's halfway there then. He's wearing Lycra, but he's not, yeah, he's halfway there, but he's not moving. Really tight Lycra in this case. Yeah, I mean, it can also be body weight exercise as well. Yeah. Because, you know, I spent some time with the move nat community who are interested in using your body in a sort of human animal kind of way so they don't lift weights they lift boulders they don't um you know swim they don't go to a swimming pool they might swim
Starting point is 00:44:36 in a river you know things like crawling i spent a morning crawling in a park in london my goodness i mean i really could not move crawling the next day. Yeah. Yeah. I mean, it was quite incredible. So it doesn't necessarily have to be that complicated. And even so the main change that I've made to my working life to get more movement in is rather than sitting at my desk all day, I spend a lot more time sitting on the floor because the one thing about sitting on the floor, you have to get up and you know, you're, you're leg pressing your entire body weight every time you do that and if you're like me and you keep forgetting you've lost your pen it's upstairs you have to run upstairs get it you know up down up down yeah and studies of uh you know people in the blue zones you may have come across that places in
Starting point is 00:45:17 the world where people are far more likely to live to a hundred than anywhere else so studies of these people you know there's lots of factors that seem to feed into their long lifespan. But one of them is that they have movement as part of their everyday life. So these little old ladies in Okinawa in Japan, they have low tables and they're constantly hopping up and down from these low tables
Starting point is 00:45:36 and going out gardening and foraging and bending down and stretching up. So sort of building that kind of stuff into your life can actually improve your strength. They call them movement snacks in MoveNat, which I love because it's a bit like, you know, when you're sitting eating snacks, you know, they add up in terms of calories without you really noticing. And, you know, that can have a real physical effect. It's the same for movement snacks.
Starting point is 00:45:58 They add up over time. You don't notice that you're hopping up and down from the floor, but you're still strengthening your legs. You're still improving your overall strength. So it all counts. And the less you're doing in the first place, the more a small amount will have an impact. So it doesn't have to be going out and becoming arny
Starting point is 00:46:14 and getting really big, bulging muscles. And in fact, that's the other thing about strength training. The improvements in mental health and in feeling more confident and powerful, they happened before any physical changes were detectable in the muscles. So it's not even that you have to build more muscle. It's just letting your body know that you can do it and that the strength is there. And it sort of releases a bit of latent potential that you didn't necessarily know you had.
Starting point is 00:46:39 So yeah, you don't need to get buff. That's not necessary at all. I'm Jason Alexander. And I'm Peter Tilden. And together on the Really No Really podcast, our mission is to get the true answers to life's baffling questions like why they refuse to make the bathroom door go all the way to the floor. We got the answer. Will space junk block your cell signal?

Starting point is 00:47:56 signed Jason bobblehead. It's called Really No Really, and you can find it on the iHeartRadio app, on Apple Podcasts, or wherever you get your podcasts. All right, dance. Let's talk about dance.
Starting point is 00:48:10 Of all the exercises that we've talked about, probably the least number of listeners are doing. Yeah, yeah. Very, very few people dance. When we get to adulthood, we seem to stop dancing, which is a real shame. And it's a really fundamental part of what it means to be human. So no other creatures dance. Or if they do, they're dancing a different rhythm that we can't work out. But they don't dance like we do to the beats,
Starting point is 00:48:34 the 120 beats per minute like we do. And there are lots of theories about why that is that humans are dancers. And one of the things is that it helps us bond. This whole point of needing each other and needing to be socially bonded dance is a way of bringing us together and so the idea behind this is that when we're moving you know we have these so proprioceptive inputs that so that's slightly different to interoception it's it's the bodily sense of where our body is in space without having to look. And that's an important thing of knowing who I am and where I end and you begin. So when we're moving, we have this proprioceptive sense
Starting point is 00:49:10 of where our body is in space. If we're moving in synchrony with somebody else, then the information about their body movements coming in through our other senses, our brains get confused. They can't really separate the two. And so this sort of breaks down the barrier between me and you and we start to feel more connected. And there's all these intriguing experiments where they get people to move in time together and then they get them to do kind of gambling tasks and they can either stuff each other's chances of winning or they can cooperate and everyone goes home happier. And people are far more likely to cooperate with each other when they've moved together first. So there's something about being a human, caring about other humans, feeling connected, that moving together just makes
Starting point is 00:49:50 happen naturally. So yeah, it can be embarrassing to dance with other people, but it doesn't have to be dance. It could be yoga, it could be Tai Chi, it could be an aerobics class, you know, it could be all kinds of ways moving in synchrony with other people. But it's something I think we're missing out on, definitely. And you can actually get the same effect on your own so i spoke to this neuroscientist called peter janata who he works on the psychology of the groove which is you know getting into the groove of music and feeling that you can't help but move your body to it and he says that when you're listening to music that's made by other humans moving their bodies that's how the sound is
Starting point is 00:50:25 getting creative you're moving along with that it's kind of like an invitation to join in with the band and so you're moving to the movements of other people and you can still get this sort of sense that you're part of something bigger than yourself so so even dancing alone in your kitchen which i do quite a lot of can help you feel connected to other people in society. So that, to me, is the most important reason to sort of get over ourselves and dance a little bit more. In this science of the groove, he surveyed a wide number of people about the grooviest song. And regardless of their musical interest, one song kind of came out head and shoulders above the rest. What was it? Let's give the listeners a second to guess. You guess, listeners. Yeah, I guess. What do you think is the
Starting point is 00:51:09 most grooviest song? I'll tell you it is not Groove Is In The Heart by Delight. So you can take that one off your list, even though it's pretty groovy. It's probably up there, though. It might be. All right. Now you can tell us. Okay. Okay. I think everyone who ever heard this will get it immediately. It's Superstition by Stevie Wonder. And the reason why maybe is because it's got this syncopated beat. So you're not just stomping along to the beat, which does do something amazing to us. We sort of, we feel connected to the beat. We feel empowered that we're going along to it and we get this boost of dopamine.
Starting point is 00:51:39 We feel good. But the syncopated beat, it's sort of like a secret rhythm. We can decode it and then we can sort of roll our hips and move their arms around and then you kind of feel groovy i mean it's an old it's an outdated word but we're bringing it back for neuroscience and one idea about you know why this makes us feel good is that there are the balance organs of our inner ear are connected to the limbic system which is the brain's sort of emotional control sensor so when we're sort of dancing we're sort of almost falling and catching ourselves
Starting point is 00:52:11 and the syncopated beat gives us this it's a bit like you know in the same way a joke makes us laugh because it sets up expectations and it violates it it pulls out the rug from under our feet and we laugh because it's funny the same sort of thing happens when we're trying to follow a syncopated beat we're almost falling over and we catch ourselves and we feel good. And so we have this kind of lovely feeling that we just feel amazing. And that's why we can't help but move our bodies to it. So I love that. I can't resist superstition. That was played a lot in my university years and gets me grooving every time. So yeah, dancing is good. I've taken up the occasional just putting on a song and you might call what I'm doing jumping around more than dancing, perhaps my old punk rock days. But hey, you know, it does work. thing called the rock and roll threshold where when the music is above this threshold i think it's 120 decibels i could be remembering it wrong but anyway when it's loud enough people start
Starting point is 00:53:09 moving they can't help but bob and you know even if it's just a stomp of the feet and a bounce of the head you can't help it and so you know sort of pogoing along it's a sort of dancing that you could do anywhere in the world if someone was drumming and you wouldn't look down it's the kind of you know that toddlers do when they first start moving with the beat before they realize they're supposed to be embarrassed and they're supposed to not do that. Yeah. You know, stomping around and, you know,
Starting point is 00:53:30 bashing the air with your fists. It makes you feel good. So yeah, you can do it by yourself. It's okay. Yeah. And it still works. I actually had the most embarrassing experience joining in with a freeform dance group
Starting point is 00:53:44 that I went to sort of as part of my research and it was it was pretty embarrassing the whole thing when we were wafting around you know just move move as your body wants to and you and I was like my body doesn't want to move my body wants to go home this is awful but when the beats got going and you know the whole room was just stomping along it was amazing and and by the end of it I had this sense that I wasn't moving my legs and arms. They were moving me. I was just along for the ride. And it was just this amazing feeling.
Starting point is 00:54:11 I was on a total high for days afterwards. And, you know, this was how we got out of our minds and just enjoyed being rather than thinking before, you know, we invented other ways of getting out of our minds. And it works and it's free and you can do it and you can still drive home afterwards. So, yeah, it was a bit of an eye opener for me, I have to say. I did a conscious movement, free form movement class virtually. And did you keep your camera on? Yeah. Yeah, we did. And my partner was here with me.
Starting point is 00:54:38 And yeah, that's a strange experience, you know, like just move in the way your body wants to move like you. I was like, my body wants to hide in a chair in the way your body wants to move like you I was like my body wants to hide in a chair in the corner the minute you've suggested this yes exactly don't ask my body it has no idea yeah but um yeah over time I began to unwind a little bit and enjoy it yeah I mean I sort of had a word with myself because I was hanging on to the radiator in the corner of this sort of drafty village hall and I thought thought, you know, seriously, the only way you're going to look ridiculous in this situation is to stand there and not do anything. These people don't know you. I mean, I had quite a few friends that said, I'll come with you. That sounds funny. I'm like, no, absolutely not. I'm going on my own.
Starting point is 00:55:15 That's what I was saying. Having my partner here in the house with me almost made it worse. You know, it would have been easier with a group of strangers. You did another of the things that I suspect would be really great, but watching it from the outside, it looks painful to even be a part of, which is laughter yoga. Yeah. Yeah. It even gives me a nervous laugh just even thinking about it. But the reason for doing laughter yoga is that studies suggest that laughing, a proper belly laugh, is a better workout for your abs, for your core than crunches. So, I mean, ideally, you would have friends that make you absolutely crack up a lot and, you know, make your belly sore at the end of it. But if not, then laughter yoga is another way of going about it. But yeah.
Starting point is 00:56:08 You still look skeptical. Yeah. I don't get the sense you're going back. No, no, I don't really think that is my thing. Luckily, I have very funny friends and a funny husband and a funny child and a dog that I could either laugh or cry at most of the time because he's such a ridiculous animal. But what kind of dog? And now I got to ask.
Starting point is 00:56:25 We've talked about him twice now. He is a collie crossed with a New Zealand hunterway, which is basically they took Welsh collies to New Zealand and thought we need a bigger dog that can be more demanding. It can run up mountains and it can bark at the top of its lungs for 14 hours straight. So he's quite demanding. Wow. Yeah. I don't know what I do. I do know what I was thinking.
Starting point is 00:56:46 I was thinking I want a dog and I like collies. And I didn't really read up enough about Hunter Ways. I don't recommend it unless you really want to run up and down hills. But he's great. Hey, well, he gets you moving. He's a great character. He gets me moving. And, you know, there's really no option.
Starting point is 00:57:00 If you've got someone, he doesn't do what my previous dog did, which is just come and stare at you until you take him out for a walk. You can ignore a stare. He will come and literally bark in your face and you go, someone, he doesn't do what my previous dog did, which is just come and stare at you until you take him out for a walk. You can ignore a stare. He will come and literally bark in your face and say, fine, fine, I'll take you out. So, yeah, it's not negotiable for him at all. And seeing him, you know, I was saying before about, you know, if other animals dance, maybe we just can't tune into it. When he cuts together with other herding breeds, it's like they click into each other. Right.
Starting point is 00:57:22 OK, you go on the inside. I'll go on the outside. And they just run in circles. And it's like their form of dance. And you okay you go on the inside i'll go on the outside and they just run in circles and it's like a form of dance and you can see that they just feel amazing when they're doing it so maybe we just can't tune in i've had mutts in the past that have a significant amount of collie in them the herding instinct is fascinating to watch in them yeah it's very strange isn't it yeah i have a boston ter She's old, but she's still active. And she does, I call it her ball or her bone dance. She loves her ball. And sometimes she loves a bone. And basically, she just gets on her back and rolls. Like, I mean, she doesn't roll. She gets on her back and wiggles on top of this thing she loves just over and over and over and over again. I mean, it looks to all the world like she is dancing. Yeah. We call it doggy break dancing. Yeah. Django does that too. My dog does that too. He likes a bit of break dancing. He usually teams it with a, it's like he's singing and dancing when
Starting point is 00:58:14 he's doing it. You have to be a mad dog person to understand. I know. I know. We're going to, we're going to have to pivot here so that we don't turn this entire show into dogs. Stretching is another part of the book, another type of movement. So I want to make sure people get all of them. We've got walking, strength training, dance, the core, stretching. But where we're going to end is breath control. I've been very interested in breath work over the last year. We had James Nestor on who wrote a great book about the breath. But you brought up some really great
Starting point is 00:58:45 things there also. And I wanted to start with meditation. And the most common style of meditation probably is to sit and just follow your breath. Don't control it. Just follow it and observe it. But you talk about how a scientist or two got interested in, hey, what's happening in the benefits of meditation? Is it something to do with what's being done with the mind or is it something to do with what's being done with the breath? Can you share a little bit more about that? Yes. This was sort of trying to tease apart whether it's the act of mentally focusing on the breath that gives you these sort of changes in brain function and the way that you feel or whether it's something to do with the breathing. And it's really interesting that the actual act of breathing through your nose, in and out through your nose, what you're basically doing is harnessing your brainwaves and sort of taking their rhythm under control, which sounds completely out there. But it kind of makes sense when you think about
Starting point is 00:59:45 the way that the brain works. And again, it's all about getting information from your environment and then using that sensibly to improve your chances of survival. So when you're taking in breath through your nose, there's a lot of information about the environment, how safe or rewarding it is in that. And so this information goes to the olfactory cortex which is sort of the top of the nose and then to make use of that information what you then need to do is to get other brain areas so the bits that are to do with memory to make sense of what this information means and then emotional responses you know does this make me scared does this make me happy whatever and for all those different brain regions to talk to each other they need to be on the same brainwave frequency and so as a result of that working of the brain when we breathe in
Starting point is 01:00:30 and out through our nose the whole brain starts to synchronize and beat to the same rhythm and when we slow down our breathing that has effects of slowing down brainwaves that they propagate through the brain so even as i'm saying, it sounds so far-fetched, but this is what studies are showing with EEG, which is looking at the frequency of brainwaves across the brain. And so when you really, really slow it down, so this particular experiment was looking at when you slow your breath down to three breaths per minute,
Starting point is 01:00:59 so that's really quite difficult to keep up. In fact, in the study, a few of the volunteers actually fell asleep during the study because they were so relaxed. They just drifted off. But that can sort of take you into this altered state of consciousness where you are more in a sense of being rather than thinking. You know, I'm not big on sitting around. This explains why all these expert meditators commit to all this sitting around and breathing slowly and can actually do this for this long, because it takes you to this amazing state of just being and being at one with the universe. I haven't managed it myself, but it seems worth aiming for to me. I would definitely fall asleep. Sleeping is like my
Starting point is 01:01:41 thing. I can definitely fall asleep anywhere but at different rates you know six breaths per minute is a lot easier to do and that's if you get people to breathe at different rates the one that they tend to say that was the most comfortable and relaxing is six breaths per minute and interestingly in studies of things like chanting reciting the rosary in latin sort of these sort of prayer-based practices, studies of those have found that it tends to naturally make people's breath go to six breaths per minute. So it's almost like humanity's worked out that this is how you feel good, this is how you feel calm and held and looked after. So breathing at six breaths per minute
Starting point is 01:02:19 has all kinds of benefits. It fills your lungs more effectively, it activates the vagus nerve, which calms the whole nervous system down. And so it's just this very easy, I mean, it doesn't even beat you when you think about movement, but this is a voluntary movement that our species can do, and not many others can, to sort of override just the in and out of oxygen into our bodies, and to take control. And that can change the way that we feel. And it's such a simple thing. You don't have to be fit. You don't have a simple thing. You don't have to be fit. You don't have to be strong. You don't have to be able.
Starting point is 01:02:47 Anyone can do it. It's really, really important thing to do. And we don't know yet how important it is or whether it makes any difference if you do that breathing whilst moving. So I find that when I'm breathing and moving, that's how I get myself into that kind of calm state is by doing yoga and focusing on breathing. But it seems that there is a small amount of evidence that it might be even more effective if you're moving and breathing at calm rate at the same time. So you maybe hit more of these buttons. You get the core exercise. You get the strength.
Starting point is 01:03:21 You get the breathing. You get the stretching. All of these things in one. exercise, you get the strength, you get the breathing, you get the stretching, all of these things in one. Yeah, it's one of the things about yoga that when I take it in a class that I wish is that it would slow down, you know, because you're moving on the in and the out breath, you know, is that the movement would span a longer breath, more to that, you know, five in, five out count, which is, that's what six breaths per minute works out to, right? Five on the inhale, five on the exhale. So the kind of yoga that I really fell in love with sort of about 10 years
Starting point is 01:03:49 ago, more than that now, is Ashtanga. And you don't follow the instructor. You do your own pace, right? You do your own pace. And that's when it really clicked for me that I wasn't breathe in now, breathe out now. I was like, well, how do you know when my lungs are full? You know, but if you're doing it at your own pace, you can really, you can really feel it when you get going. I have got into that state of being and just calm and awareness of my body. And it's an amazing feeling. And you don't necessarily get that if somebody's dictating your breath. That's right. That's right. Yeah. Yeah. I always find that I'm like, the speed is off for me. Yeah. I found the six breaths per minute,
Starting point is 01:04:25 I think certain people call it coherent breathing. Fascinating that that is the rate that ties to a lot of ancient prayer type practices. And then three breaths per minute does take a little bit of effort. But it's interesting. I'm practicing a little bit differently now. But for a while, I was a very focused Zen Buddhist. So I was really doing that type of meditation. But if you go back further into the Zen tradition, there is talk about controlling your breath in a way that doesn't typically show up in what we think about with meditation. And it was about this very light. So you're not moving a lot of air. But you're doing it, you know, closer to what you're describing, which is that, you know, three breaths per minute. That's really interesting. So yeah,
Starting point is 01:05:12 you don't have to be sort of huffing and puffing and making a real effort. But what you're doing is sort of taking control and sort of controlling the rate. The research would suggest that what you're doing is really sort of slowing down the activity of the brain and then that can get you into this state of zen i guess you know the state of being and being at one with the universe yeah and i think that's what makes slow breathing hard for a lot of people is we tend to equate slow breathing with deep breathing which we then sort of naturally equate with moving a lot of air. So there's this like, you know, this strong, you can't inhale that forcefully for 10 seconds. Like it doesn't work that way. It's a much lighter moving less air over a longer period of time. Anyway, thank you so much, Caroline, for coming
Starting point is 01:05:58 on the show. Thank you so much for this wonderful book that teaches us so much about how to move. And you've just got a line, which is basically the message is move more in your brain will thank you in the long run and in the short run. Absolutely. Yeah. Yeah. Your life will be better. Yeah. I mean, what's the worst that can happen? You've moved, you get healthier, you've had a good time. Yeah. You can always sit down afterwards. And you know, the end of the book, I talk about rest and the importance of rest. It's not about necessarily getting more exercise in. It's about moving your body around more.
Starting point is 01:06:31 And it doesn't have to hurt. You don't even have to change your clothes and shoes. You just have to remember that you're an animal that needs to move and stretch and breathe and make sure you do that. Well, thank you so much. Thank you very much for having me.
