1. The Correlation Between Lung Health and Longevity
Timestamp: [00:29]

James Nestor begins by addressing a pivotal question: "Is there a correlation between our health outcomes, how long we'll live, and our lung capacity of VO2 max and all of that stuff?" Steven Bartlett (Speaker A) echoes this curiosity, indicating a shared interest in understanding the vital role of lung health.

Key Points:

• Lung Size and Lifespan: Nestor references the Framingham study, which observed 5,200 individuals over 70 years, revealing that those with larger and healthier lungs tended to live longer.
• Lung Transplants as Evidence: Studies on lung transplant recipients showed that those receiving larger lungs had increased longevity compared to those with standard-sized transplants.
• Natural Enhancement of Lung Capacity: Emphasizes that lung capacity can be improved without surgical intervention through practices like healthy breathing, stretching, and exercise.

Notable Quote:
"The healthier and larger your lungs are, the longer you will live. That is the greatest indicator of lifespan." – James Nestor ([00:29])

2. The Downward Spiral of Deteriorating Lung Function
Timestamp: [02:28]

Bartlett and Nestor discuss the self-reinforcing cycle where declining lung capacity leads to reduced exercise capacity, further diminishing lung health.

Key Points:

• Age-Related Decline: Lung function begins to decline rapidly after age 30, with significant decreases in women around their 50s and 60s.
• Breaking the Cycle: Engaging in breathwork, exercise, and yoga can stave off lung deterioration and maintain overall health.

Notable Quote:
"Your lung function starts dropping off very quickly. ... You can practice healthy breathing, we can practice stretches, we can exercise, and this naturally can keep our lung size up." – James Nestor ([01:15])

---

3. Practical Breathing Techniques for Enhanced Lung Capacity
Timestamp: [04:52]

Nestor provides a hands-on demonstration of biomechanically effective breathing techniques to expand lung capacity and improve respiratory function.

Key Points:

• Awareness and Biomechanics: Emphasizes the importance of conscious breathing and proper technique.
• Step-by-Step Instructions: Guides listeners through specific exercises, such as placing hands above sit bones and collarbones to monitor lateral expansion during inhalation.
• Integration with Physical Activities: Highlights how these breathing techniques can enhance performance in activities like yoga and cardiovascular exercise.

Notable Quote:
"When your hands are moving out laterally, if those hands are separating on your chest, you are taking a proper biomechanical breath." – James Nestor ([05:27])

---

4. The Impact of Stress and Anxiety on Breathing Patterns
Timestamp: [10:22]

The conversation shifts to the interplay between stress, anxiety, and breathing, shedding light on how modern lifestyles contribute to dysfunctional breathing patterns.

Key Points:

• Fight or Flight Response: Chronic stress keeps individuals in a sympathetic (fight or flight) state, leading to shallow and rapid breathing.
• Health Implications: Dysfunctional breathing due to stress is linked to high blood pressure, metabolic dysfunctions, and other health issues.
• Breathing as a Stress Reset Tool: Simple breathing exercises can activate the parasympathetic nervous system, promoting relaxation and reducing anxiety.

Notable Quote:
"The quickest, most effective way, way more than drugs to take control of this stress, is to take control of your breathing." – James Nestor ([17:13])

---

5. Techniques to Activate the Parasympathetic Nervous System
Timestamp: [15:31]

Nestor elaborates on specific breathing techniques designed to shift the body from a sympathetic to a parasympathetic state, thereby mitigating stress and anxiety.

Key Points:

• Extended Exhales: Encouraging longer exhalation times (e.g., inhale for 4 seconds, exhale for 6) helps activate the parasympathetic response.
• Heart Rate Variability (HRV): Improved breathing patterns can enhance HRV, a key indicator of autonomic nervous system balance.
• Practical Exercises: Demonstrates breathing sequences that can be subtly performed in everyday situations to induce calmness.

Notable Quote:
"This was such a simple hack. But so many of us have these wearables. You can check it for yourself in real time to look at your heart rate variability, changing your breathing pattern." – James Nestor ([20:33])

---

6. Chronic Stress and Its Effects on Breathing
Timestamp: [18:07]

The duo discusses how chronic stress leads to persistent sympathetic activation, resulting in compromised breathing and overall health deterioration.

Key Points:

• Chronic Stress Consequences: Prolonged activation of the fight or flight response contributes to autoimmune issues and other health problems.
• Breathing as Preventative Care: Regular practice of effective breathing techniques can prevent the adverse effects of chronic stress.
• Meta-Stress Loop: Stress affects breathing patterns, and dysfunctional breathing, in turn, exacerbates stress, creating a vicious cycle.

Notable Quote:
"We live in an environment where we are always activating, always pushing towards that sympathetic and it's making us sick." – James Nestor ([17:10])

---

Conclusion

In this enlightening episode, James Nestor and Steven Bartlett uncover the profound connections between breathing, physical health, and mental well-being. By understanding and practicing effective breathing techniques, listeners can enhance their lung capacity, reduce stress, and improve overall longevity.

Transcript

[A]

Packages by Expedia. You were made to occasionally take the hard route to the top of the Eiffel Tower. We were made to easily bundle your trip Expedia made to travel flight inclusive packages are atoll protected. Is there a correlation between our health outcomes, how long we'll live, and our lung capacity of VO2 max and all of that stuff? Is there a correlation there?

[B]

So I had the same question years ago and I started looking into it and it turns out that numerous studies have found that the healthier and larger your lungs are, the longer you will live. That is the greatest indicator of lifespan. Was lung size and lung health the greatest indicator? The greatest indicator. According to these studies, the Framingham study looked at 5,200 people over the course of 70 years. And they found that the people who lived the longest had the largest and healthiest lung function. They even did studies in which they were looking at people who had lung transplants. So surgically implanted lungs, those who were given larger lungs lived way longer than those given normal size or smaller lungs. So no matter how you get these larger lungs, it's better. And luckily we don't need to get a transplant to do this. We, we can practice healthy breathing, we can practice stretches, we can exercise, and this naturally can keep our lung size up. It's very sad when you start looking at these charts of what happens after you're 30. You're almost there, so get ready. It's a real bummer. But your lung function starts dropping off very quickly. And especially for women around 50 and 60, your lung function and your lung size starts shrinking, shrinking, shrinking up, which means at the time you need more oxygen more easily. It's much harder to get that. And that's where people's health really starts disintegrating and they start having problems. The good news is you can stave off this deterioration, this shrinking of your lungs by doing all the stuff we're talking about by doing breath work, exercise by exercise. What is yoga but stretching and breathing into this lung and breathing into that lung? So the yogis knew this thousands and thousands of years ago.

[A]

And it's the, it almost feels like that downward spiral is kind of self reinforcing and self fulfilling. Because if my lung capacity deteriorates, my movement and my exercise capacity will deteriorate, which means my lung capacity will deteriorate, which means I'll move less, which is kind of this downward spiral, right?

[B]

Absolutely. And it's my belief after studying this stuff for so long that that is the thing you want to pay attention to. More than anything else, especially as you grow older, your lung function, how much air you can pack into your lungs, how long you can hold your breath. All of this is indicative of your general respiratory function and your general health. So that little hint of using a breath hold every morning to see where you are physically and mentally, I think is good. They've used it for thousands and thousands of. And now it's coming back. This is something that a lot of these longevity experts aren't looking into. They're looking into nutrition and exercise. They're not looking into lung capacity. We get more energy from breath than we do from food and drink. Right. We take 30 pounds of air in and out of our lungs every single day. And so I find it interesting, they're focused on all these micronutrients. All that stuff's important, right? I believe most of it. But from what I know, a lot of them aren't focused very much on their breathing.

[A]

I want to make sure that I have something that I can take into my own life there for the expansion of my lung capacity, because I'm sold on the importance of it. So exercise expands my lung capacity.

[B]

Yeah, 15, 20% just by exercising. By virtue of. Actually, if you're a good exerciser, your lung capacity will stay up.

[A]

Cardiovascular exercise.

[B]

Cardiovascular exercise. There's ways to access that a little more. If you're dysfunctionally breathing when you're working out, you're not doing yourself too many favors. So you have to remember those simple, basic things. You have to learn how to take a proper breath, then apply that to your workouts. You will see such an incredible difference once you do this. This is what yoga is good for. It's hard to do yoga without breathing well, right? You can do it. But by virtue of all those different poses, they're meant to open up your chest, right? To expand this area.

[A]

So yoga, cardiovascular exercise with proper breathing through my nose, breath work practices, the.

[B]

Start of the day, I think biomechanics, the first thing is awareness to any of this stuff. You can take your hands. We can do this while we're seated here. You can put it above your sit bones here. And when you breathe in, breathe very, very low. And you want your hands to move out laterally. I don't care what your stomach's doing. Moving out laterally. So as you breathe in.

[A]

When you say low, you mean in my belly.

[B]

You want your hands to be moving outwards. Okay? I don't care what's happening with your lung, with your stomach. I can hold my breath and move My stomach in and out. So when people talk about a belly breath, that's not what we're doing. When your hands are moving out laterally, that means your diaphragm is descending. That's how we can see if you're taking a proper deep breath. So as you breathe in, you want your hands to be moving outward. And if you take a cloth measuring tape, you can actually measure your progress this way. The next thing you want to do is take your hands. Okay. Take your four fingers, place them on your collarbone, and put you. This one's very weird. Place your middle finger right there so it's only your middle finger that's touching. Okay. And we're going to breathe deep. Then we're going to move that breath up into our chest. Okay. Dome of your shoulders. You want to see those fingers naturally separated. Okay. So this is not a flexing thing. Your shoulders stay down like this. Just like this. Fingers on the collarbone. We're going to take a big breath into our lower abdomen area. Move it up. And you want your chest to be expanding outward. The last thing we want to do. Take your hands and put them. Especially you. You need to do this. Take your hands, put them around your neck.

[A]

Yeah.

[B]

I want you to do that same breath. You should feel zero tension in your neck. There's none of this going on. Okay. It should feel soft and supple. So let's take that belly to the chest breath. If there's any tension, do it again until there's no tension. Okay, now try that again, keeping your shoulders down. Okay. Do not move your shoulders up. There's none of this going on. You're very soft, very relaxed. Take your hands above the hip bones. When you're breathing in very deep, those hands should be out like this. Like wings.

[A]

Yeah.

[B]

Okay. And you're going to breathe in deep. And those hands should be moving out laterally. You will start to feel those organs getting compressed. That's good. You want that? Then you can move it up one more time. So we're going to start low, and we're going to move that breath up to the chest. Keep your shoulders down. Try it again. Keep the shoulders down. There you go. Those fingers should be separating, so this is something that you can check in. If those hands are moving out laterally, if those hands are separating on your chest, you are taking a proper biomechanical breath. And that's what you need to focus on. And you'll notice once you start learning how to access these different areas, you start applying this to working out and your performance will tend to go up. You'll be less exhausted at the end. You'll just feel better all around.

[A]

So we should expect our chest to kind of move outwards as we breathe in.

[B]

You want to see your chest moving outwards, because most of your lungs, the expansion is in your back. But some of that is going to be happening. This is not a pose that you want to do like this, right? You should be very loose, very limber. And when you breathe in, you want that air to fill all the way up there. But you want to start low first. That means the diaphragm is descending. Most of the air that is soaked up from the lungs, and that gas exchange happens at the bottom of the lungs. So you want to be able to access the bottom of those lungs.

[A]

Is there a certain way that I. Because when you say you want to start by breathing at the bottom, how do I know? So the symptom of me breathing at the bottom, is it coming out? My sort of. What do they call this? My abdomen coming outwards on the sides?

[B]

That's right, because everyone calls this a belly breath. So people do this with their belly. But you can move your belly independently of your breathing. This is a way that you can't cheat. So a tape measure is good. And if you get an inch, inch and a half, that's pretty good. But you can work that up. And if you see really good breathers, people have practiced a lot of yoga and done it the right way. They can have this massive expansion. And this is what ties into freedivers. Free divers are the experts at accessing every square inch of their lung capacity to fill it with air. That's what they do. Which is why if you ever see free divers go to one of these competitions, they. They're short people, tall people, fat people, whatever. They all have these enormous chests because they've been able to develop this incredible lung capacity.

[A]

One of the things that I think causes shallow breath is this kind of constant state of fight or flight stress, anxiety, screens, social media. And it's funny, because whenever people would have been listening to this podcast and started, heard you talk about breath, and they would realize that they were probably at that exact moment doing really shallow breaths. You talk about these free divers who are able to extract, you know, 80, use 80, 90% of their diaphragm or more, where you said we use 10, roughly 10%.

[B]

This is about 10%, and oftentimes less than that, the average person.

[A]

What is the correlation between, like, stress and breathing? And also, I'm talking now about like the everyday angst of life.

[B]

So we've talked about the skeleton, we've talked about anthropology, we've talked about biomechanics and posture. But something else that ties into this, you're 100% right, is psychology is your brain. So how you breathe affects how your brain works, affects your anxiety, but your anxiety also affects how you're breathing. So again, it's another one of those circles. What happens so often is when we're at work, we're so sensitized to threats and to fear that we overreact when something happens even though it's not threatening our life. We get a nasty email from a friend or a email from the boss that's disappointed at the last project you did and we get stressed out, right? And so what is the physiological response to stress is we clench up, we hold our breath and then we breathe like this, and we hold our breath again and we breathe like this. You think about thousands of years ago when we were out in the wilds, what would we do if there was a threat approaching? You'd hold your breath to be silent and then you breathe too much to get your respiratory system ready to either fight it off or, or to run away. So we're having the same response in our day to day lives now because we're so over sensitized to it. So researchers have different names for this. They call it email apnea or continuous awareness. I mean there's an academic name for it, partial attention syndrome. I prefer email apnea. Easier to remember no matter what you call it. It's the idea that when you're in the office place, you're breathing dysfunctionally because of this constant stress loop. And they found, there were some NIH studies on this. They found that breathing this way can have long term damage to your health, high blood pressure issues, all the things we had talked about, metabolic dysfunctions and more. Which makes sense because you're just constantly in this loop of fear and threat and stress. So the quickest, most effective way, way more than drugs to take control of this stress, is to take control of your breathing. And this has been documented time and time again. So when you notice your breathing this way, you stop. What I like to do is breathe two breaths in and then an exhale. Looks like that resets your respiratory system, that resets your breathing pattern. Then you can do a few rounds of that and go back to very simple five second in, five second out. So let's just pretend you're in line at the airport. Someone's cut you off. You ordered something at Starbucks. They gave you the wrong. You know, all the things that are just drive us crazy nowadays at that moment. Want you to breathe in. Pause, breathe in again. Let it out. Relax yourself a little bit when you're doing these breaths. Okay? Breathe in. Breathe in again and let it out. Do that one more time. Breathe in a little more subtle. Let in again and let it out. So you did this in a very exaggerated way, which is fine, but you can do this so no one can tell you're doing it. You can do it very subtle. You probably feel a little different now than you did before.

[A]

Yeah. So much different.

[B]

You can return to then a slow, low, rhythmic breathing pattern from there or whatever makes you comfortable. I like five seconds in, five seconds out. Also, what's beneficial for people if it's comfortable for them is four seconds in.

[A]

Six.

[B]

Six out will really mellow you out. And we could try that right now. Breathe in. Okay, first of all, slow. I should not be seeing you.

[A]

Okay, you shouldn't see.

[B]

Okay, so we're going to breathe in just very, very lightly. We're going to relax here.

[A]

Why does it matter if you see it?

[B]

Because you're trying too hard.

[A]

Okay?

[B]

This is not. There is a time and place for the. This is not it. Okay?

[A]

Okay.

[B]

Right, so breathe in, 2, 3, 4. Out. 2, 3, 4, 5, 6. Breathe in, 2, 3, 4 dot Out. 2, 3, 4th, 5, 6. Doesn't have to be that exact pattern, but this will trigger all of that parasympathetic response in your body. You can see this if you're looking at your heart rate variability. It's amazing to see the difference that this happens just after a few breaths. Looking at your hrv, looking at your heart rate, looking at your stress levels.

[A]

What is it doing? You mentioned parasympathetic and resetting the respiratory system. But if I, you know, what is the parasympathetic and the respiratory system for dummies? What is that?

[B]

So how you breathe is going to activate your nervous system function. Your nervous system function is going to activate everything in your body. So we can take conscious control of our breathing. We can't take conscious control of our heart rate or liver function or any of that. We can take control of our breathing. When we take control of our breathing, we can hack into our nervous system. So you can be in a sympathetic state, just like we were. You take a couple of those double inhales and exhales.

[A]

What's sympathetic state?

[B]

Sympathetic state is the act, the fight or flight. This is the action part of your nervous system. When you're in this state, you are ready for action and what happened, which is great. We want to be ready for action. We want to be ready to fight or run away from stuff. We do not want to be in this state all day long.

[A]

Anxiety, angst, stress, anxiety, stress.

[B]

Because this is where autoimmune issues and so many other problems come from by constantly staying stressed. We want stress, we want to be able to access stress for short amounts of time. Then we want to flip back into this parasympathetic, this relaxing state. If you look at, once again, animals in the wild, you even look at like a gazelle that's been attacked, you know, five minutes later, it's just sleeping. So it has a nervous system that's able to pivot from one to the other. Unfortunately, we live in an environment where we are always activating, always pushing towards that sympathetic and it's making us sick. Really, really sick. So your breathing is the quickest way of taking control of acute stress. So pills work okay, other modalities work, but in that moment is when you need the most help. And your breathing is the thing that can get you there.

[A]

So people that have chronic stress must have awful breathing.

[B]

Absolutely. And they've documented that. They've looked at their breathing, they've looked at their carbon dioxide levels, and carbon dioxide is indicative of how sl your breathing. If your levels are very low, that means you breathe like this. So you're just off gassing all of this CO2. And they're always low, especially for anxiety and panic as well. They're always low, extremely low. You ask someone with acute panic or anxiety to hold their breath, this is usually what happens. I'm never doing that again. I've seen this hundreds and hundreds of times. So by breathing slowly, you're making them more comfortable with more CO2. You're making them more comfortable with their nervous system, function with themselves. Which is why this assessment of a breath hold is very useful and so important. It's not only a diagnostic, it's a therapeutic. Because while you're holding your breath, you're also in the action of training yourself to tolerate more CO2, which will calm your body down.

[A]

And going back to this point about the parasympathetic and the nervous system and anxiety, why does having an extended exhale help with anxiety? So you said breathe in for four, breathe out for six. Why does extending that exhale by two seconds help with stress and anxiety?

[B]

So if you really pay attention and a lot of people have problems doing this, which is why it's helpful for them to look at their whoop or whatever. You can place your hand over your heart and when you inhale, you can feel your heart rate increase. When you exhale, it slows down. This is how HRV works. This is how it's calculated, is the difference in time on that and the shortest distance to the longest difference. And this is looking at your nervous system function. Respiratory, sinus, arrhythmia. So how you breathe affects how how many times your heart beats. Right. So if you're exhaling, which slows the heart rate down more, what's going to happen to your heart rate? It's going to start slowing down more. And that exhale, that slowing down and telling your body you're in a safe place, that it can relax is what triggers this response by the nervous system.

[A]

Interesting. So it's like tricking the body into believing that.

[B]

Such a simple hack. And a lot of people, they say, oh, this can't be true. But so many of us have these wearables. You can check it for yourself in real time to look at your heart rate variability, changing your breathing pattern. Look at your blood pressure too. For many people, they can just switch their breathing. After a couple of minutes you can see drops of 15 points. Not for everybody, but for some people, 10 to 15 points just by switching your breathing.
