1. How to Sleep Like a Pro: Nose, 4-4-6-2, Repeat

“Breathe deeply and regularly…Try to breathe through your nose, keeping your mouth closed if at all possible. The more you breathe through your nose, the easier you will find it to breathe through your nose. In other words, use it or lose it.”

- Dr. Barbara Oakley and Olav Schewe, Learn Like a Pro

I didn’t expect to find anything about breathing in a book called “Learn Like a Pro,” which is geared mainly toward college students. But, to learn well, you need to sleep well. Enter: the power of the breath.

And their advice for falling asleep? Inhale for 4 sec, hold for 4 sec, exhale for 6 sec, hold for 2 sec. “This type of breathing balances both the oxygen and carbon dioxide levels in your body and allows you to relax more deeply.”

It’s just so awesome to see slow nasal breathing make its way into random places like this. If put into practice, these few sentences could change a student’s life forever. Simply amazing.

Here’s to sleeping (and learning) like a pro, tonight.

P.S. I’ve been having a little self-induced stress insomnia recently (such is life), so it was perfect timing for this passage.

2. Beating Gravity with Your Nose

“The results presented in this work provide evidence that the development of a substantial production of NO in the upper airways of humans may be an important part of our adaptation to life on two legs to ameliorate the influence of gravity on pulmonary blood flow distribution.”

- Nasal nitric oxide and regulation of human pulmonary blood flow in the upright position

Translation: Nasal nitric oxide might have been an evolutionary adaptation to counteract gravity, allowing us to sit and walk upright. 🤯

Gravity moves blood flow toward the base of the lungs. Nitric oxide, however, redistributes blood flow help better utilize the massive surface area of the lungs. This allows us to get more oxygen in the upright position.

So go take a walk, breathe through your nose, oxygenate your body, and enjoy this gift evolution has given us.

3. Psychology Today: “The Simplest Stress Management Skill”

“It may seem incredible that such a simple exercise can make a huge difference in a person’s ability to feel less stressed.”

- Dianne Grande, Ph.D., The Simplest Stress Management Skill

Of course, that “simple exercise” is slow deep breathing : )

This quick and excellent article touches on the vagus nerve and equal versus extended exhalations. It also provides some straightforward and practical guidelines for a “minimum effective dose” of slow breathing. Enjoy!

4. The Making of the Present Moment

“Your experience of the present moment is based on the activity of your nervous system at that moment. ”

- Rick Hanson, Ph.D., Neurodharma

We are always in the moment. As Howard Cohn says, “In truth, we are always present. We only imagine ourselves to be in one place or another.”

So what “presence” really refers to is experiencing our current moment. And as Dr. Hanson reminds us, our experience of any moment is just our nervous system at that moment. And the fastest way to access that? Our breath.

So experience your breath to experience presence. Or better yet, change your breath, change your nervous system, and use this science and physiology of presence to make your own moments.

Hey,

Welcome back to another issue of The Breathing 411. Here are 4 thoughts, 1 quote, and 1 answer for this week.

I hope you enjoy it!

 
 
 
 

4 Thoughts


1. Posture is Easier with the Breath

“Question: Do I start with breathing correctly or addressing my posture?

Answer: Breathing comes first. Aligning your body correctly will come more easily once you have your breathing down. Plus, most cues to help with posture end up making a person tighten more rather than relax on the inhale.”

- Belisa Vranich and Brian Sabin, Breathing for Warriors

I constantly struggle with my posture (but only all the time 😂). So, I loved this answer from two of the world’s leading experts on the topic.

Additionally, as we’ve all probably experienced, you can’t really get a good breath unless you have good posture, so they really go hand-in-hand. Good breathing leads to better posture, and good posture leads to better breathing.

So sit up straight, take a relaxing breath, and enjoy the rest of this post : )

Related Quote: “What the bodily form depends on is breath (chi) and what breath relies upon is form. When the breath is perfect, the form is perfect (too)…Consequently, breath and form must be accomplished together.” - Chinese adage from The Primordial Breath (but I found it in Breath)

2. Fixing Hyperventilation Easily with Slow Breathing

“The mechanism by which hyperventilation is targeted by HRVB has not been proven, although it is reasonable to hypothesize that it involves a combination of slow breathing, decreased emotional and autonomic reactivity, and attention to breathing mechanisms for controlling it.”

- Applied Psychophysiology and Biofeedback (2020)

Because slow breathing increases HRV and improves autonomic and emotional reactivity, it naturally reduces your stress. It naturally improves your sensitivity to carbon dioxide. And it naturally optimizes gas exchange.

All of this helps you breathe calmer more often.

So to fix hyperventilation easily, maybe we don’t need to fix it at all? Perhaps we should just enjoy our slow breathing practice and, with time, let our improved physiological state naturally lead to optimal breathing volume.

This approach won’t be suitable for everyone, but if you struggle with overbreathing, this might be the best place to start.

***

P.S. Ironically, when people start a slow breathing practice, they often overcompensate for the slower rate by taking bigger breaths and end up mildly hyperventilating. For this reason, many researchers and coaches (myself included) suggest that slow breathing is not enough—we must also focus on breathing volume. However, as pointed out in this 2020 meta-analysis, slow breathing might self-correct with time.

3. Scientific American: “Proper Breathing Brings Better Health”

“Breathing is so central to life that it is no wonder humankind long ago noted its value not only to survival but to the functioning of the body and mind and began controlling it to improve well-being.”

- Scientific American

This is perhaps my favorite online article published about breathing. But, I realized I have somehow never shared it here.

I especially loved a part near the end. It’s almost as if the author is surprising himself with all the benefits of breathing as he’s researching and writing the article, and he can’t believe this stuff isn’t widely used:

“In fact, I am mystified that controlled breathing is not recommended and practiced more widely. Perhaps it is perceived as too simple, commonplace and obvious to be a remedy.”

Those were my exact feelings when I found “breathing.”

Enjoy the excellent read!

“Every atom in your body that is heavier than helium was made inside a star, usually as it was exploding.  Carbon, oxygen, iron, all of it. Take a breath, and breathe stardust with stardust. This body is billions of years old.”

Delightful Practice, Reverse Arambhashura, and The Buddha’s Take on Science

 
 

Listen Instead of Reading

 

Hello,

Here are four thoughts, one quote, and one answer for this week.

I hope you enjoy it!

 
 
 
 

4 Thoughts


1. What Science Has in Common with The Buddha

“Research in general tells us something about most people. Given that our concern is for what we, rather than what most people, should do, current medical practice alone cannot have a definitive answer…We need to learn how to integrate what the medical world knows to be generally true with what we know, or can find out, about ourselves.”

- Ellen Langer, Ph.D., Counterclockwise

Ellen Langer was the first woman to be tenured in Harvard’s Psychology Department. She’s a badass, and this book is insanely good. If you’re interested in applying scientific research in your own life, it’s a must-read.

The above passage is particularly critical for breathing. As we continue to learn new things about breathwork, the most important thing is to integrate that knowledge with our personal situation to find out what’s best for us.

And remember, just because it worked in a study doesn’t mean it will work for you.

As the Buddha supposedly said, “Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense.” It seems like Dr. Langer would agree : )

How do we do this in our own lives? Let’s turn to another brilliant mind for more advice in Thought #2.

***

Related Quote: “I believe books are medicine. A library is a medicine cabinet. What can heal one person may not work at all for somebody else. You know when something is healing you, just as you know when something isn't.” - Sandra Cisneros (I know it’s about books, but still so good.)

2. Delight in Practice: How To Integrate Science Into Your Life

“So look for what feels good and meaningful in what you’re already doing, and perhaps find additional things that are naturally pleasurable for you…Practice is less effective if it’s heavy and somber most of the time. It’s ok to have fun with it.”

- Rick Hanson, Ph.D., Neurodharma

How’s that for a book title? There was no way I could not read that one : )

It’s packed with insight, but I thought this passage paired perfectly with Thought #1. To begin applying the new things you learn about breathing, start with what you already find meaningful, and add on from there.

For example, suppose you love the Oxygen Advantage. But, then you learn that taking big breaths every now and then is beneficial for lung capacity. In that case, you might try adding 5 big breaths before each breath hold you perform. If you like it, you keep it. If not, you don’t.

We also don’t want to take it too seriously (often guilty here). As Dr. Hanson also tells us, “It’s good to bring playfulness, even delight, to your practices.”

Here’s to applying rigorous science in our lives in a delightful way, today.

“A brief review of the latest science on breathing and the brain, and overall health, serves as a reminder that breathing deserves much closer attention – there’s more going on with each breath than we realize.”

- David DiSalvo, Forbes Magazine

Here’s a quick summary of some of the science-backed benefits of breathing from Forbes. It was written 2017, but just as relevant today.

I liked the headline-paragraph-headline-paragraph style. Concise and informative. I hope you enjoy it too!

4. Slow Breathing as Reverse Arambhashura

There’s a Sanskrit word, arambhashura, which means something like “hero in the beginning.” We’ve all been there. You start a project all excitedly, but the excitement wanes. You hit some roadblocks. You decide it’s not worth it.

A slow breathing session is like reverse arambhashura. Because of the positive breathing-relaxation feedback loop, you gain motivation as you go. And when you’re done, you’re more focused, relaxed, and happy than when you began. You’re a hero at the end.

Here’s to practicing a little reverse arambhashura today.

How To Breathe To Live Longer, plus a New Take on "Breathe Light"

 
 

Listen Instead of Reading

 

Greetings,

Here are four thoughts, one quote, and one answer for this week.

I hope you enjoy!

 
 
 
 

4 Thoughts


1. How To Breathe To Live Longer

Let’s synthesize some ideas on breathing for longevity and see how we can apply this knowledge in our own life today.

Part I: Breathe Through Your Nose

Here’s James Nestor describing how George Caitlin lived double the average life expectancy of his time:

“He credited his longevity to ‘the great secret of life’: to always breathe through the nose.” - Breath

Part II: Expand Your Lung Capacity

Next, here’s Nestor describing the Framingham Heart Study:

“They gathered two decades of data from 5,200 subjects, crunched the numbers, and discovered that the greatest indicator of life span ... was lung capacity … larger lungs equaled longer lives.” – Breath

Part III: Synthesis and Application

Part I is straightforward: breathe through your nose. But how do we expand lung capacity? Nestor provides a few different ways.

  1. Light to moderate exercise

  2. Lung expanding breathwork

  3. Long and complete exhales

Lung-expanding breathwork includes things like Wim Hof w/ “belly, chest, head,” the Yogic Complete Breath, and most breathing taught in freediving.

Long exhales also increase lung capacity by allowing “more air to get in” on the next breath. But, they have the added longevity benefit of activating the “relaxation response.”

Alright, so there we have it. To live longer, we should breathe through our noses all the time, increase our lung capacity, and practice extended exhales.

And for the ultimate expression of longevity, let’s not forget what Michael J Stephen, MD tells us in Breath Taking:

“Those of us who practice breathing exercises today may well pass on more disease resistant genes to our descendants tomorrow.”

Here’s to living longer, today. : )

***

Related Quote: “For breath is life, and if you breathe well you will live long on earth.” - Sanskrit Proverb

P.S. Here’s how I implement this in my life:

  • Nasal breathing 24/7.

  • 15 min of slow breathing in the morning w/ extended exhales.

  • 5-10 min of slow breathing before bed w/ extended exhales.

  • Practice Wim Hof style breathing, ~5-10 min a day.

2. A New Definition of “Breathe Light”

You’ve probably heard of Patrick McKeown’s fantastic Breathe Light exercise. But, motivated by this excellent post, I decided to add another definition of “breathe light:”

Perform slow nasal breathing in the sunlight.

Nasal breathing releases nitric oxide into the airways and carries it into the lungs. Sunlight liberates nitrite from your skin and increases circulating levels of nitric oxide. When combined, you get better blood flow and oxygenation.

As Dr. Steven Lin says in the post,

Sunlight + Slow Breathing = Health + Happiness

3. “Vision and Breathing May Be the Secrets to Surviving 2020”

“Stress, he says, is not just about the content of what we are reading or the images we are seeing. It is about how our eyes and breathing change in response to the world, as well as the cascades of events that follow.”

- Scientific American

I know, I know, it’s 2021. But I’m a slow reader : )

In any case, this is an excellent article from Scientific American. Breathing, stress, vision, and Andrew Huberman—it’s just all-around amazing.

I hope you enjoy it as much as I did, if you haven’t already read it…

P.S. Thanks to Ben Greenfield for sharing this article, which is how I found it.

Hey,

Here are four thoughts, one quote, and one answer for this week.

4 Thoughts


1. Why We Should (and Should Not) Care About HRV

“Over the years we've experimented with many different types of physiological and psychological measures. Heart rate variability (HRV) patterns… have consistently emerged as the most dynamic and reflective of our inner emotional states.”

- The Heartmath Solution

I’ve been on an HRV kick lately. And although I’m fascinated by the physiological implications of it—its correlation with disease and diabetes, its impact on stress, and so on—here’s another reason we should care: It’s the “most dynamic and reflective [measurement] of our inner emotional states.”

Of course, this makes perfect sense, as our emotional states impact our physiology, and vice-versa. HRV gives us an index for them all, which is why we should care about it.

But, we should also remember that high HRV isn’t the end goal. It’s the positive states associated with high HRV we’re after.

So here’s to using slow breathing to maximize HRV while (paradoxically) remembering that HRV is not the end goal.

***

Related Quote: “‘When a measure becomes a target, it ceases to be a good measure.’ Measurement is only useful when it guides you and adds context to a larger picture, not when it consumes you.” - James Clear, Atomic Habits

P.S. Huge thanks to Crussen for The Heartmath Solution. After taking his genuinely incredible Heart Coherence class, I contacted him, and he said Heartmath helped inspire it. I immediately grabbed the book and loved it.

2. The Positive Breathing-Relaxation Feedback Loop

“Slow breathing techniques with long exhalation will signal a state of relaxation by VN, resulting in more VN activity and further relaxation.”

- Frontiers in Human Neuroscience, 2018

Here’s a positive feedback loop we can celebrate: Slow breathing sends a message of relaxation via the vagus nerve, which increases vagal activity, further enhancing relaxation. Thank you, complicated physiology.

Practically, this is why when you start your slow breathing practice, you don’t feel much at first, but after a few minutes, you feel like a different person. You’re experiencing this positive breathing-relaxation feedback loop in action.

Complex science. Simple to experience.

Give it a shot today.

***

Related Quote: “Not only does VN control heart rate and slow deep breathing, slow respiration rates with extended exhalation could also activate the PNS by VN afferent function in the airways. This is a form of respiratory biofeedback.” - Same paper as above

3. A Wealth of Health | Breathing: Misconceptions and Tips (and Wim Hof’s Mastery)

“Taking control of the breath — consciously thinking about the unconscious respiratory mechanism — is the first step to improving a plethora of everyday struggles and habits.”

- The Breeze, Breathing: Misconceptions and tips

I picked that quote because it goes perfectly with Thought #4 below on Lucid Breathing. But the article is packed with information (and name drops, 😂). It covers a lot of ground, somewhat disjointedly, but I think you’ll enjoy it.

My favorite part was a reminder of something I often forget: That Wim Hof is a master of the breath (and marketing). Although his method frustrates many in the breathing community, James Nestor nailed it in this article:

“Everyone thinks that Wim Hof is breathing ‘Wim Hof breaths’ all the time,” Nestor said. “He’s not. He’s breathing like that for 20 minutes, and the rest of the time he’s breathing really slowly, and he’s humming.”

Enjoy!

4. Are Lucid Breathers the Future of Evolution?

“It seems to be only around 20 to 30% of the population are actually natural lucid dreamers…Maybe those 20 to 30% of people who do lucid dream are at the forefront of hominid evolution, and they are going to be the next species of preference. We just don't know.”

- Matthew Walker, Ph.D.

Maybe the same is true of lucid breathers? Interestingly, Nature made it difficult to control our dreams. It made it simple to control our breath—though most of us sleep right through it.

But control over our breath was not an accident. As Belisa Vranich and Brian Sabin tell us in Breathing for Warriors, “It's an invitation, an opportunity to take part in our own nature and evolution.”

So wake up in your breath. Use it to control this dream we call living.

How Breathing Improves HRV, Sleep, and “Keep Breathing. That’s the Key”

 
 

Listen Instead of Reading

 

Greetings,

I realized that last week marked one year of The Breathing 411—and 2.5 years of sending a weekly breathing newsletter. 🤯

Writing this newsletter is my favorite thing in the world to do, so thank you for reading, sharing, and practicing these ideas.

Alright, here are 4 thoughts, 1 quote, and 1 answer for this week.

Enjoy!

1. The Mechanisms of How Breathing Improves HRV

“Inhalation causes an immediate rise in heart rate, followed (∼5 s) by increased blood pressure and baroreceptor firing. Exhalation results in an immediate decrease in heart rate followed (∼5 s) by decreased blood pressure and baroreceptor firing.”

- A Practical Guide to Resonance Frequency Assessment for Heart Rate Variability Biofeedback,
Frontiers in Neuroscience

Have you watched the Huberman Lab video showing how breathing immediately impacts heart rate? Check it out. The above passage explains how that process goes on to improve HRV.

Specifically, it’s that ~5-second lag between the rise and heart rate and rise in blood pressure that’s critical. And it’s this lag that makes breathing at a 5in/5out rhythm so beneficial (although it’s slightly different for everyone).

When we breathe like this, the messages from our breath and blood pressure synchronize, increasing their amplitude and increasing HRV.

Thus, there’s to magic behind how slow breathing improves HRV. It’s simply a harmony of body messages, which increases efficiency and, subsequently, improves resiliency and overall health.

Related Quote: “The optimum breathing rate is about 5.5 breaths per minute. That’s 5.5-second inhales and 5.5-second exhales. This is the perfect breath.” - James Nestor, Breath

2. Breathing’s Version of Powered In, Unplugged, and System Restarts

  • Nasal breathing is like having your computer plugged in. You’re getting a constant supply of energy via your power chord (nose and nasal airways).

  • Mouth breathing is like unplugging from the charger. Sometimes it’s needed, and you can make it for some time, but eventually you’ll run out of juice.

But suppose you keep your computer plugged in 24/7, even at night when you close your laptop (via mouth tape).

What happens in that case? Well, even then, you’ll eventually have too many things running. You’ll need a restart.

Methods like Wim Hof/SKY/Tummo serve as this restart for your nervous system. They clean out all the junk, allowing you to return to your baseline.

Here’s to using our breathing to optimize our energy and meet whatever demands our systems have.

3. “Can Breathwork Help You Sleep? An Expert Explains”

“If you want to engage in breathwork for sleep, don’t get too hung up on the details. The key is to slow down your breath and really direct it to your belly using your diaphragm.”

- Can Breathwork Help You Sleep? An Expert Explains

In this article, Molly Atwood, an assistant professor of psychiatry and behavioral sciences at Johns Hopkins University, explains why deep breathing is so helpful for sleep. It’s super quick and practical—I loved it.

It was especially refreshing that there was nothing fancy or complex: “It’s not a super complicated thing to practice,” she says. “I think it would be hard to find something that would steer you completely wrong.” Amen, and enjoy!

4. Turning Breathing Knowledge into Breathing Wisdom

“But not until that moment…did that knowledge become wisdom, that is, become how I felt.”

- Alex Lickerman, MD, The Undefeated Mind

What a perfect distinction for when knowledge becomes wisdom: It’s that moment when something you know becomes how you feel.

Here’s to turning breathing knowledge into breathing wisdom through continuous learning, practice, and insights.

P.S. Dr. Lickerman also describes an insight as “that most mysterious of experiences in which knowledge takes root in a person’s psyche and alters what he believes and therefore how he behaves.” Love it.

Nerdy Warriors of the Breath, Investing, and a Useful Look at HRV

 
 

Listen Instead of Reading

 

Greetings,

Here are four thoughts, one quote, and one answer for this week.

Enjoy!

 
 
 
 

4 Thoughts


1. A Practical Look at HRV and Resiliency

“Resilience is the ability to return to normalcy, according to Jen Baker, director of athletics and recreation at John Hopkins University, a graduate of the US Naval Academy. It's your ability to bounce back and thrive, replace worry with objective things, to navigate and take steps forward.”

- Belisa Vranich & Brian Sabin, Breathing for Warriors

Slow breathing significantly increases heart rate variability (HRV) and, subsequently, increases resiliency. This has been shown time and time again. But, from a practical perspective, what does it mean to “increase resiliency?”

Does it mean you’ll never experience stress or anxiety again? No, certainly not. What it means is that the stressors won’t feel as severe and, as Jen Baker says, that you’ll bounce back faster. The stress is the same. You’re different.

So here’s to not trying to escape the world and its stressors, but instead having the tools—one being slow breathing—to bounce back to normalcy faster.

Related Quote: “To say that learning breath control is the most important component to forging mental toughness would not be an overstatement.” -Mark Divine, Retired U.S. Navy SEAL Commander

Related Quote: “By modulating the stress response via vagal stimulation from conscious breathing exercises, people can bolster their resilience to all forms of negative stressors; diabetes is no exception.” - Evan Soroka, Yoga Therapy for Diabetes

2. Where Are You Investing Your Breathing: GameStop or Real Estate?

Slow breathing methods can be “life-changing,” according to James Nestor. But, “they can also take a while, especially for those with…chronic conditions.” On the other end of the spectrum, he says methods like Tummo restore balance with a “violent shove,” which can also be helpful for some.

So how do you know which is right for you?

I liken it to investing. Slow, nasal breathing is like putting your money in real estate or an index fund. It’s pretty safe. There will be fewer ups and downs, and you’re almost guaranteed a positive return.

The “violent shove” techniques, on the other hand, are like investing in GameStop or crypto. You might see some incredible benefits in just one day. But, you also risk a significant loss the next if you're not diligent with it.

So the question is: Are you looking for short-term gains or long-term compounding? Are you timing the market or playing the long game? Maybe you want to have a “diversified portfolio” : ) There’s no right or wrong answer. Only you know which approach is right for you.

3. “'Email Apnea' Is a Real Thing-Here's How to Stop Holding Your Breath While Working (and Feel Less Stressed)”

“Learning (and really practicing) basic breathing techniques can also help reverse the effects of email apnea; it'll help you improve awareness of your own breath and breathing habits and teach you how to breathe more easily during times of stress.”

- Real Simple, ‘Email Apnea’ is a Real Thing

This article provides an excellent summary of email apnea and some practical things you can do to reduce how often it occurs. Or, at the very least, to help reverse some of its harmful effects.

As someone who still (after years of a daily breathing practice) occasionally experiences this, I thoroughly enjoyed the read. I hope you do too!

4. Nerdy Warriors of the Breath

“The old-school philosophers knew it was really hard to live in integrity with our highest ideals. They told us we needed to be WARRIORS of the mind, not mere librarians of the mind.”

- Brian Johnson

Meaning we have to live our philosophy, not simply recite it to other people. The same is true with breathing. But, with breathing, both are critical.

We have to be warriors of the breath. We have to live it and practice it, in easy and difficult circumstances. But, we also need to be librarians of the breath.

We need to have the science ready in our back pocket. We need to intrigue people with the experience, then back it up with the science, or vice-versa.

So here’s to being nerdy warriors of the breath, accomplishing great things with our practice, and then explaining the physiology of how it worked : )

Extra Thought: Breathing I’m Exploring

I try my best to be a breathing warrior, and I practice every single day. I don’t share too much about it because everyone’s practice is their own. But, here are a couple of new things I’ve tried recently:

Breathwrk App: I’ve been having fun doing 1-3 min of each breath they offer. I use it sporadically throughout the day just to try something different. My three favorite breaths so far are:

  1. No Worries

  2. Clear Mind

  3. Calm

Open: I’ve also taken a few on-demand breathwork classes through Open. I usually enjoy being in control, but I have genuinely loved these classes. Here are my two favorites (thanks Crussen!):

  • Heart Coherence (this one was truly incredible)

  • Symmetry (box breathing w/music—an excellent mix)

Here’s to never-ending growth, learning, and exploration of the breath.

Phil Mickelson, and How Modern Science Helps Explain 2000-Year-Old Wisdom

1. The Real Lesson from Phil Mickelson: For Diabetes, and Life in General

Phil Mickelson used controlled breathing throughout the PGA Championship. So, when he won, it was an exciting moment for the breathing community.

But do you know what happened for the next tournament? He played poorly.

Of course, with sports, we accept that this is just part of the game. Even with his focused breathing, no one can win them all.

But do you apply this concept in your life, especially if you have diabetes?

Do you remember that life is more complex than sports? There’s no “one thing” that will ensure you always win.

But, and this is important, Phil still finished that next lousy round of golf. He didn’t just walk off the course because he wasn’t winning.

And that’s what we have to do. A high blood sugar doesn’t mean we should give up on our protocol. A poor night of sleep doesn’t mean this breathing stuff doesn’t work. Life is hard, and we all have off days. But, that’s precisely when we need our fundamentals the most.

Here’s to knowing we’ll have bad days and weeks, and finishing anyway, knowing we’ll eventually be on top again.

***

P.S. I know nothing about golf, so thanks to my dad for pointing out how bad Mickelson played when we hung out on Father’s Day, sparking this thought : )

2. Breathing is a Scalpel to Your Brain and Emotions

In 2017, a group of Stanford researchers discovered a small cluster of neurons that control your breathing—the breathing “pacemaker neurons.”

It turns out that these neurons extend to other parts of the brain that control emotions, and it’s a two-way street: The emotional areas can influence your breathing, but your breathing can also influence them.

On a recent RadioLab Podcast (aptly titled “Breath”), after learning this, Molly Webster likened her breathing to a scalpel to her brain and emotions:

“I feel like, in a way, he almost gave me like a scalpel to get inside my own brain and control it…If I actually change my breathing, it will change this breath pacemaker region, and it will send an ‘I’m chill’ signal to the fight or flight directly, and it will calm down.”

This brought a massive smile to my face. What a perfect analogy.

Practically and scientifically, you can know that when you take control of your breath, you take control of a small cluster of neurons that talk to other regions of your brain. So the scalpel is right there in your nose. Use it when needed.

4. Moderate Breathing, in Moderation

“All breathing in moderation, including moderate breathing.”

A reader helped me add this one to the list of “Breathing Graffiti.” Thanks, M. Night Larry. It’s clever, and it has lots of practical wisdom too.

Remember that we take over 20,00 breaths a day. So Wim Hof is OK now and then. Breath holds are OK now and then. (If you’re in good health, of course.)

All breathing in moderation, even moderate breathing. That’s a simple and valuable principle to live by.

Phil Jackson on Focused Breathing, Nature’s CO2 Trick, and Wisdom of Yoga

Hey,

Here are four thoughts, one quote, and one answer for this week. Enjoy!

1. Don’t Let Your Breathing Get Featured to Death

“The answer starts with the noble intentions of engineers. Most technology and product design projects must combat feature creep, the tendency for things to become incrementally more complex until they no longer perform their original functions very well.”

- Chip and Dan Heath, Made To Stick

Breathing practices are simple. But, as humans, we tend to make things more complex. We let “feature creep” take over (guilty here). As Chip and Dan tell us, it’s an innocent process, but sooner or later, things get “featured to death.”

Feature creep can be seen in breathing in many ways—the infinite number of methods available, the untold number of bio-monitors you can wear, the countless places you can focus each breath.

These are all awesome things, and we should always be trying to improve our breathing. But, if your practice has lost its original function (relaxation, focus, etc.), then maybe it’s creeping too far.

Here’s to keeping our breathing fun and adding things that bring it more to life, not feature it to death.

***

Related Quote: “The hardest thing in the world is to simplify your life because everything is pulling you to be more and more complex.” - Yvon Chouinard, Patagonia Founder

P.S. I find this to be more of an art than science with my practice. What’s “too much” for me might seem like “not enough” for you, so it’s very personalized.

2. How Nature Tricked Us into Thinking Carbon Dioxide is So Important

When you get interested in breathing, you eventually get fascinated by carbon dioxide (CO2). The more you learn, the more you feel like you’ve been duped the whole time: “Breathing is really about CO2, not oxygen.”

Everywhere you look, this makes sense:

It just seems like CO2, not oxygen, is the star of breathing.

But just when you think you have it figured out, Nassim Taleb reminds you of the brilliance of Nature:

“It is all about redundancy. Nature likes to overinsure itself. Layers of redundancy are the central risk management property of natural systems.”

- Nassim Taleb, Antifragile

Ah-ha, reading this passage through the lens of breathing, we see it is really about oxygen. Nature is just smarter than us.

Nature built in layers of redundancy to ensure we always have enough—from our perspective, it seems wasteful. But paradoxically, that wasteful appearance is precisely due to how vital oxygen is.

As Taleb says, “Redundancy is ambiguous because it seems like a waste if nothing unusual happens. Except that something unusual happens—usually.”

There’s no real practical wisdom here, just fun to consider the genius of Nature and evolution. Here’s to never-ending learning and never-ending 🤯

3. Breathe through Your Nose! Modern Research Confirms the Wisdom of the Yoga Tradition

“Quite rightly, it revealed that breathing through the nose led to a 10 – 15% higher oxidation of the blood.”

- Eddie Weitzberg, M.D. Ph.D.,

Breathe Through The Nose! Modern research confirms…

Of course, if I see an article that starts with “Breathe through the nose!” I’m going to read it and share it : )

And even better, this one was written by one of the pioneers in nasal nitric oxide research, Dr. Weitzberg. He was part of the (now somewhat famous) study showing nose breathing increases oxygen by 10-20%.

It’s a quick read and a good reminder of how powerful nasal nitric oxide is.

Enjoy!

P.S. Check out the 3rd paragraph in the grey box titled “Nadi Shodana – to counter asthma.” It’s the best explanation I’ve heard for pinching your nose closed on a breath hold.

4. Phil Jackson on Focused Breathing Before a Big Game

“When we made it to our banquet room, five minutes ahead of schedule, every player was already in his spot ready to sit and breathe together.”

- Phil Jackson, Foreword in The Mindful Athlete

This was the morning of Game 7 in the 2002 Western Conference Finals. The Lakers won in overtime. Phil Jackson said the players kept the same cool on the court in overtime as they had in the banquet room breathing together.

Did they win because of breathing? Of course not. But did it help? Probably.

As Phil goes on to say:

“A lot of athletes think the trick to getting better is to just work harder, but there is a great power in non-action and non-thinking. The hardest thing after all the work and all the time spent on training and technique is just being fully present in the moment.”

Focused breathing helped the Lakers achieve just that.

Applying Gandhi's Wisdom, The Science of Learning, and $100 to Your Breath

4 Thoughts


1. Why Your Breathing Gains Get More Boring With Time

“Gaining the first $100 at the track feels much better than winning the second $100, which feels better than winning the third $100, and so on. Eventually, if things get good enough, there is almost no psychological benefit when they get even better. This relationship reflects what economists call diminishing marginal utility.”

- Barry Schwartz, The Paradox of Choice

Building off last week’s “Satisfaction Treadmill,” let’s not forget this passage when our breathing, or anything else we’re working on, starts feeling boring.

We’re still making gains. They just might not feel as dramatic, because we already feel so good.

2. Applying Gandhi’s Wisdom and Scientific Research to Appreciate Your Favorite Breathing Practice

“Humans do not give greater credence to an objective record of a past event than to their subjective remembering of it.”

- Make It Stick: The Science of Successful Learning

Translation: What you experience holds more weight than what you learn.

As the Make it Stick authors also tell us, research shows it’s “nearly impossible to avoid basing one's judgments on subjective experience.”

Some might say this is a flaw of being human—we base things on emotions instead of facts. I say it’s amazing, at least when it comes to breathing : )

Because with breathing, this means that whatever you experience is what’s true for you. Your practice is yours; no science or statistics needed.

Practically, it means that if your experience with Wim Hof was terrific, then you should keep doing it. Or, if slow breathing was life-changing, do that.

As Gandhi tells us, “As long as you derive inner help and comfort from anything, keep it.” This applies perfectly to breathing. And science agrees.

3. Mouth Tape: End Mouth Breathing for Better Sleep and a Healthier Mouth

“Becoming a nose breather is a process, but even repeated cycles of just a few minutes of nose breathing can effectively train your body to do it regularly.”

- Dr. Mark Burhenne, Mouth Tape: End Mouth Breathing for Better Sleep and a Healthier Mouth

Mouth taping is odd. It’s perhaps the most important thing we can do for our health, but it’s hard to recommend without sounding slightly crazy.

Fortunately, Dr. Mark Burhenne wrote this great article, which covers basically every aspect of taping up at night. It will now be my go-to for anyone interested in the topic.

Enjoy the great read, and enjoy sharing it with others.

4. To Take Care of Your Heart, Take Care of Your Breath

“In other words, the primary role of the heart is to distribute the oxygen brought into the lungs during inhalation, and to bring carbon dioxide back to the lungs where the excess can be breathed out.”

– Patrick McKeown, The Breathing Cure (pg. 237)

I’ve never thought of it this way: Your heart’s main job is to make your breathing useful to the rest of your body. So from this viewpoint, it’s obvious they must work together. And all the science we review makes perfect sense.

Of course breathing efficiently would make our hearts work more effectively. And of course we would see measurements like heart rate variability increase and blood pressure decrease.

That’s because the heart and breath can’t be separated. Thus, we might even say, to take better care of your heart, take better care of your breath.

Treadmills, Metronomes, and Breathing Graffiti on 28 Famous Quotes & Idioms

 
 

Listen to this post:

 

Hello fellow breathing nerds,

Here are 4 thoughts, 1 quote, and 1 answer for this week. Enjoy!

 
 
 
 

4 Thoughts


1. The Satisfaction Treadmill, and Why We Forget How Good Breathing Makes Us Feel

“In addition to being aware of the hedonic treadmill, we should also be wary of the satisfaction treadmill. This is the double whammy of adaptation. Not only do we adapt to a given experience so that it feels less good overtime, but we can also adapt to a given level of feeling good so that it stops feeling good enough.”

- Barry Schwartz, The Paradox of Choice

I thought treadmills couldn’t get any worse, but alas: the satisfaction treadmill.

It’s the reason you still enjoy your breathing or meditation practice, but aren’t sure why it doesn’t feel as good as it used to. It’s why you eat healthily, but still get excited about the latest “superfood” or supplement.

You have adapted to your new level of feeling good, which means it’s not good enough anymore. I say this confidently because I do it all the time—just ask my wife : )

This is, of course, not the best way to live, with breathing or anything else. And things like gratitude and prayer are clearly invaluable. But, in my experience, just having an awareness of the satisfaction treadmill is helpful.

Having awareness gives you space. You can decide if something really isn’t working anymore, or if you’ve simply adjusted to a new level of feeling good.

Here’s to slowing down (or even stepping off) the treadmill today.

2. Breathing as a Metronome for Centering Yourself

“Now consider your breathing like a metronome, consistently and rhythmically connecting you to your own source, and providing you with a regular mechanism for re-centering yourself.”

- George Mumford, The Mindful Athlete

Building on last week’s trampoline thought, here’s another way of looking at slow breathing. You can consider your breathing to be like a metronome, setting the tempo for many rhythms in the body.

Slow down the metronome, and you slow down and synchronize these other rhythms.

And the best part about it? You are the conductor, and the breath is always available, “providing you with a regular mechanism for re-centering yourself.”

3. Babies Do It. So Do Fitness Trainers. Now Scientists Say It Might Even Improve Memory.

“The results showed that when the participants breathed through their noses between the time of learning and recognition, they remembered the smells better.”

They also provide 3 breathing exercises recommended by Dr. Andrew Weil. Of course, we all know 4-7-8, but the “Breath Counting” one was neat too.

Breathing Know-How, and Why Trampolines Are Better than Science

 
 

Listen to this post:

 

Happy Monday,

Here are 4 thoughts, 1 quote, and 1 answer for this week. Enjoy!

1. The Ultimate Goal of Breathing Education is Breathing Know-How

“Knowledge is not know-how until you understand the underlying principles at work and can fit them together into a structure larger than the sum of its parts. Know-how is learning that enables you to go do.”

- Make It Stick

This is the ultimate goal of breathing education. Having the tools to “go do.” Fitting the principles of breathing into a coherent structure that’s larger than just “breathe through your nose” or “do the Wim Hof Method.”

Here are a few simple ways I try (emphasis on try) to do this in my life:

  • Exhaling through the mouth at the start of each slow breathing session.

  • Many short bouts of breathwalking, especially to reset between tasks.

  • Slow breathing after lunch when my blood sugars are weirdest.

And here’s a real-world example of breathing know-how used to help a 67 year old with breathlessness. (Note the range of breathing methods used.)

Here’s to building more breathing know-how today.

Related Quote: “The people I distrust most are those who want to improve our lives but have only one course of action.” - Frank Herbert

(Both of those also apply to using breathing as a cure-all too.)

2. Why Trampolines are More Useful than Science to Explain Slow Breathing

Do you remember jumping on a trampoline with your friends? You all start out jumping at different rhythms—it’s really quite awkward at first.

But then, gradually, you begin jumping together. You start synchronizing the ups and downs, and each bounce gets a little bit higher. (Then, of course, someone eventually gets “launched,” but that’s beside the point : )

The analogy is that slow breathing does this for our bodies.

We have many mechanisms working at different rhythms to keep things in balance. Your heart might get one message to slow down, but then you began to inhale, sending it a new message to speed up. There’s just a lot going on.

But when you breathe slowly, several of these messages come together and begin to work in unison, like kids jumping together on a trampoline. This synchronization amplifies your natural rhythms, making things more efficient.

So next time you sit down to breathe at 4-6 breaths per minute, remember the trampoline. And take joy in how easily you can bring your body’s chaotic rhythms into complete harmony.

3. How Slow Breathing Might Help with Allergies

“Researchers unveil relationship between presence of corticotropin-releasing stress hormone and increase in and degranulation of allergy-causing mast cells.”

- Relieve your stress, relieve your allergies

Excess stress makes everything worse. It looks like allergies are no exception.

But the point of sharing this article is this: Maybe the stress-reducing benefits of a consistent slow breathing practice could help reduce allergy symptoms?

Seems like a reasonable thought…

“Life and the breath are synonymous.”

- Michael J Stephen, MD

“For breath is life, and if you breathe well you will live long on earth.”

- Sanskrit Proverb.

From medical doctors to Sanskrit proverbs. Science journals to spiritual journeys. The breath is always equated with life.

Deductive reasoning might tell us that, if breath is life, then optimal breathing is optimal living.

A Mystical Organ, and The 4 Best Ways to Keep Your Breathing Interesting

 
 

Listen to this post:

 

Greetings,

Here are 4 thoughts, 1 quote, and 1 answer for this week. Enjoy!

 
 
 
 

4 Thoughts


1. The 4 Best Ways to Keep Your Breathing Practice Interesting

  1. Try New Methods

    • Example: Trying a new method or breathing rate each week.

  2. Make it Harder

    • Example: Gradually increasing the sides of your box breath.

  3. Use it in Harder Situations

    • Example: Using nasal-only breathing during a run or workout.

  4. Focus on Compounding (my favorite)

    • Example: Using the same method with ridiculous consistency.

…

P.S. Any #1-3 can actually be applied in #4 too.

2. How Slow Breathing Helps Lower Your Blood Sugar, Diabetes or Not

Slow deep breathing activates the calming parasympathetic nervous system. This might increase insulin sensitivity and, in people without type-1 diabetes, stimulate insulin production. The immediate result is lower blood sugar.

So, diabetes or not, these blood-sugar-balancing effects are pretty phenomenal. But if you have diabetes, the compounded benefits get even more impressive.

In one long-term study, type-2 diabetics who practiced slow deep breathing for 15 min twice a day for one year improved their HbA1c by as much as 2%.

To put that in perspective, every 1% reduction in HbA1c reduces the risk of heart attack by 14%, the risk of death by 21%, and the risk of microvascular complications by 37% in people with type-2 diabetes.

With results like these and no adverse side effects, slow breathing just seems like a no-brainer for helping manage blood sugars.

3. A Breathing Grab Bag

Here’s a hodgepodge of interesting articles to browse this week:

4. To Understand the Benefits of Breathing, Do This

“Understanding is not conceptual, and therefore cannot be passed on. It is an immediate experience, and immediate experience can only be talked about (very inadequately), never shared.”

- Aldous Huxley

My attempts to convey the benefits of breathing are “very inadequate,” at best.

I can share how breathing lowers blood sugar or increases HRV, which is fun and exciting stuff. But to understand it requires that you experience it.

So pick a method that resonates with you and go experience it for yourself. It’s too simple not to.

“We must always remember that knowledge of understanding is not the same thing as the understanding, which is the raw material of that knowledge.”

P.S. I found these passages in the Brain Pickings Sunday Newsletter.

Breathing Gives Us What Babies Want, 0.1 Hz, and The Miracle of the Nose

 
 

Listen to this post:

 

Hey,

Here’s your weekly dose of breathing and diabetes fun. Plus, a letter I wrote 10 years ago…

I hope you enjoy reading!

 
 
 
 

4 Thoughts


1. Breathing Gives Us What Babies Want

In the Paradox of Choice, Barry Schwartz discusses a fascinating study:

  • Group 1: Infants were able to control some dancing toys by turning their heads in their cribs. It made them really happy to see the toys.

  • Group 2: Got “a free ride.” They saw the same toys, but theirs just randomly appeared when the Group 1 babies made them turn on.

The Group 2 babies still found this very entertaining, at least at first. But they eventually lost interest, whereas Group 1 didn’t:

“The different reactions of the two groups caused researchers to conclude that it is not dancing toy animals that are an endless source of delight for infants, but rather having control. Infants kept smiling and cooing at the display because they seem to know that they made it happen.”

I think this study demonstrates why breathing (especially Wim Hof) is so impactful. It taps into a desire that’s in us since birth—the desire for control.

Breathing gives it to us, immediately. We can instantly change our state, and we know we made it happen, not some external force. We become Group 1.

It’s like what Barry Schwartz says when interpreting those babies’ reactions:

“I did this, isn’t it great? And I can do it again whenever I want.”


2. The Upside of Diabetes

“When I was eleven years old, I was diagnosed with Type 1 diabetes. This taught me a lot of responsibility at a young age…I have to incorporate a lot of “thinking ahead” and problem solving into my daily routine…Furthermore, it has taught me to always be positive and to be grateful for every opportunity I have…Although I do not enjoy having diabetes, it has definitely had a positive impact on my life.”

I wrote that 10 years ago when I was applying for graduate school.

Fast forward to today, and it’s often depressing researching about breathing and diabetes. As excited as I get about breathing, I’m also continuously reminded of all the ways diabetes is ruining my health. Thanks, science.

But in reality, I’ve always felt that diabetes is the best thing to ever happen to me. And I still 100% agree with everything I said 10 years ago.

I’m not saying diabetes doesn’t suck. But, I try not to forget that it could be a lot worse and that it has had many positive impacts on my life.

So here’s to keeping a positive outlook, while simultaneously being realistic, knowing that we need to take extra good care of our bodies and health.

…

P.S. This was inspired by my recent re-reading of The Upside of Stress.

3. How Slow, Deep Breathing Taps into A Natural Rhythm in Our Bodies

“Noble’s research demonstrates how tiny mechanisms throughout our cardiovascular system oscillate at that same frequency of 0.1 Hertz. ‘It’s almost like an inherent rhythm,’ he says. ‘Your breath may be unlocking this rhythm that you already have going on in the background.’”

- How Slow, Deep Breathing Taps Into A Natural Rhythm In Our Bodies

I read this article first thing in the morning with a cup of coffee. It was so good, I think I starting buzzing at 0.1 Hz : ) It’s just so awesome seeing “breathing” continue to seep into popular resources like Discover Magazine.

Read it, practice it, share it, and enjoy it. As they say in the article, “All you need is a pair of lungs, and some discipline.”

…

P.S. Another reason this was so much fun to read was because a 411 reader sent it to me. It’s my favorite thing in the world when you all send me such good stuff. Thanks, as always, “Midnight Larry!”

4. How To Get The Benefits of Breathing Without the Mastery

“Happily, the benefits of training in meditation arrive long before mastery does.”

- Sam Harris

The same is true for slow breathing. And it’s simple to get the benefits of breathing without mastery: Just get started.

I still suck at breathing. I’m continuously working on it. But I’ve seen incredible benefits because I practice every single day.

So don’t worry about perfection or mastery. Just get started. The best way to do that? Just four minutes a day—two in the morning, two before bed.

…

P.S. This was inspired by a +1 from my favorite teacher, Brian Johnson.

Slow Breathing Really Does Help Everything, According to a 2020 Study

 
 

Listen to this post:

 

Hey,

It’s a fun post this week. Lots of good info, plus one of the best real-life breathing videos you’ll ever see.

I hope you enjoy it!

 
 
 
 

4 Thoughts


1. Slow Breathing Really Does Help Everything, According to a 2020 Study

“The results of this review provide evidence that HRVB and PB at approximately six breaths per minute have positive effects on a variety of physical, behavioral, and cognitive conditions.”

- Heart Rate Variability Biofeedback Improves Emotional and Physical Health and Performance: A Systematic Review and Meta Analysis

Good news. I’m not crazy, which is how I often feel after every paper I read leads me to say that “slow breathing helps with just about everything.”

But, that’s also the conclusion of a recent 2020 meta-analysis.

They found that, like we discuss all the time, slow breathing won’t “cure” any one particular thing. But, it does help many different things in small ways:

“The overall effect sizes are modest but highly significant, suggesting that these methods may not be sufficient for treating any one problem but may be useful as a complementary intervention.”

Amen to that. And like you already know, when combined and compounded, these small improvements add up to overall better health.

To learn more, click here and read my short summary of the study.

Or better yet, don’t read it. Instead, spend those few minutes breathing slowly and experiencing the positive benefits for yourself : )

2. Diabetes Really Does Hurt Everything, According to Our 2020 Life Experience

Just kidding. Well, kinda.

But I believe the meta-analysis above in thought #1 highlights why slow breathing can be so beneficial for diabetes.

As we know, when not properly managed, diabetes hurts just about every aspect of health and wellness:

  • Anxiety

  • Distress

  • Autonomic function

  • Emotional regulation

  • Cardiovascular function

  • And on & on

So, if slow breathing helps many of these, even modestly, they’re still going to add up to considerable benefits for our diabetes control.

Of course, it’s not a cure-all. But slow breathing is possibly the simplest, safest, and most effective thing we can do to address many diabetic problems.

3. Breathing Exercises for Kids: Everything Parents Need to Know

“The cure? Take a deep breath. That sounds like a useless platitude. It’s not.”

- Breathing Exercises for Kids: Everything Parents Need to Know

Wow, this was a surprisingly good article. Quick and easy, and full of good information. It did have one typo about CO2, but I’ll let it slide since they provided so many awesome breathing books I can now get my daughter : )

And since they also provided this excellent advice for our children, nieces and nephews, and really just everyone in general:

“You practice every day, you slow breathe every day, even when you’re not anxious, and then even though you become a little bit anxious, you have the bandwidth to not fall off the edge.”

- Dr. Umakanth Katwa,
Director, Sleep Laboratory at Boston Children’s Hospital
Professor at Harvard Medical School

Sounds good to me.

Enjoy the excellent read!

4. Words Are Not Always Adequate, or Important

“Again, the likely explanation is that what is most easily put into words is not necessarily what is most important.”

- Barry Schwartz, The Paradox of Choice

This is certainly true for breathing.

Heart rate variability, autonomic function, blood pressure, blood flow, anxiety, distress. Slow breathing helps them all, and they all sound good.

But are they what’s truly most important?

I think that 21-second YouTube video above is what’s most important.

And I don’t have words for that.

Coherent Breathing, Diabetes, and How All Top Performers Use The Breath

 
 

Listen to this post:

 

Thanks for clicking on another issue of The Breathing 411.

Here are 4 thoughts, 1 quote, and 1 answer for this week. Enjoy!

 
 
 
 

4 Thoughts

1. Why We Should Practice Coherent Breathing, in just Two Sentences

“When oscillations of two or more systems are synchronised it increases physiological efficiency by enabling the functions of these systems to be coordinated. This prevents energy being wasted on non productive functions.”

- The Functions of Breathing and its Dysfunctions and Their Relationship to Breathing Therapy

Coherent (or resonant) breathing synchronizes different body systems, and I thought those two sentences perfectly summarized why it’s so important:

It improves efficiency and conserves energy.

To experience this yourself, you might think finding your particular resonant breathing rate requires special biofeedback equipment…and you’d be right. 

Fortunately, however, a 2006 study found that we get most of the benefits by simply breathing at 5-6 breaths per minute. Meaning you can get started right now without any fancy gear. It’s as simple as using a phone app.

Here’s to synchronizing our breathing for optimal efficiency today.

Related Quote: “Did it matter if we breathed at a rate of six or five seconds, or were a half second off? It did not, as long as the breaths were in the range of 5.5.” - James Nestor, Breath

P.S. The two apps I recommend are iBreathe and BreathWrk.

2. All Things Breathing and Diabetes

Patrick McKeown and I sat down a couple of months ago to talk about all things breathing and diabetes. It was a surreal experience to be chatting with the person who has taught me so much. We covered a lot of material from both personal and scientific perspectives.

Watch the full interview on YouTube here.

I hope you enjoy watching and listening.

3. Mick Fanning’s Breathwork is the Key to His Success

“Fanning’s performance coach, Nam Baldwin says breathwork is the foundation of mental and physical performance.”

- Mick Fanning’s scoliosis led him to breath work. Now, it’s key to his success

Aside from diabetes, one reason I became interested in breathing was surfing. So, when I saw this headline, I couldn’t wait to read it.

And it was better than expected. It was impossible to pick just one quote to share, so here’s another gem from Mick himself:

“You can change your moods, your thought patterns, just by concentrating on breath… and the better you breathe the better you perform.”

Enjoy the great read!

4. Maybe All Top Performers Focus on Their Breath?

And it’s not just Mick Fanning. In The Mindful Athlete, we learn that many top-performing teams and athletes use breathing as a critical component of their practice. They might not use “breathwork,” but they certainly make focusing on their breath a daily routine, especially before games:

“If they're mindful athletes, most of them are actually bringing their attention not to the game ahead, but to the present moment: fully concentrating on their breathing and, in doing so, centering themselves in that calm place where they are able to be in touch with the space between stimulus and response.”

- George Mumford, The Mindful Athlete

We’re all athletes in the game of life. (Having a chronic disease like diabetes makes each day like the Super Bowl.) We might not have personal trainers, nutritionists, or millions of dollars. But we all have the breath. And we all have access to the same control and awareness that these top performers do.

Let’s use it wisely.

1. Study Shows How Slow Breathing Induces Tranquility

“Breathe slowly and smoothly. A pervasive sense of calm descends. Now breathe rapidly and frenetically. Tension mounts. Why? It’s a question that has never been answered by science, until now.”

- Stanford Medicine News Center

We all know that slow breathing calms us, and fast breathing stimulates us. But in this great article, we learn that there are specific neurons “spying” on our breathing, “reporting their finding to another structure in the brainstem.”

Enjoy the interesting read!

Breathing Through Negative Feedback Loops, and the WHM in 2.5 Minutes

 
 

Listen to this post:

 

Welcome back to another issue of The Breathing 411.

Here are 4 thoughts, 1 quote, and 1 answer for the week. Enjoy!

 
 
 
 

4 Thoughts

1. The Epiphenomena of Breathing

“However, a lightbulb also produces heat. Heat is not the function of the lightbulb, nor is it the reason we originally fashioned it […] It is an unintended by-product of the operation, not the true function. Heat is an epiphenomenon in this case.”

- Matthew Walker, Why We Sleep

Depending on you and your perspective, breathing can have many epiphenomena. For example, you might do a breathing practice to relax. But, as a by-product, it will also improve autonomic and cardiovascular function.

Perhaps your breathing practice is for better sleep. In this case, you’ll still experience the epiphenomena of better insulin sensitivity and better focus.

In fact, optimal breathing has so many “epi-benefits,” it’s hard to keep track. Luckily, you don’t have to. You simply pick one or two reasons that make sense for you, and let the rest happen on its own, like heat from a lightbulb.

Related Quote: “Replace the habit of taking short shallow breaths into the top of the lungs with the practice of taking a full deep breath. Nearly all of the benefits begin with this one simple change.” - Al Lee, Don Campbell, Perfect Breathing

2. The Negative Feedback of Stress in Diabetes, and What We Can Do About It

  • Diabetes is a chronic stressor. [1]

  • Chronic stress worsens blood sugar control. [2]

  • It also reduces HRV, increasing susceptibility to more stress. [3]

  • This then can increase anxiety. [4]

  • Leading to more stress and worse blood sugar control. [2]

  • Which then leads to the subjective feeling of more stress. [1]

It’s a merciless cycle.

Encouragingly, however: “Emerging evidence strongly suggests…that interventions that help individuals prevent or cope with stress can have an important positive effect on quality of life and glycemic control.”

You probably know where this is going : )

Slow breathing immediately helps:

  • It reduces chronic stress by increasing vagal tone. [5]

  • It improves both short- and long-term HRV. [6]

  • It reduces anxiety. [7]

  • It improves blood sugar control. [8]

The negative feedback loop of stress and diabetes won’t just go away. But slow breathing gives you an effective intervention you can use to help offset its harmful effects and prevent it from getting out of control forever.

Related Quote: “Slow breathing could be a simple beneficial intervention in diabetes.” - Nature Scientific Reports

3. How The Wim Hof Method Works, In 2.5 Minutes

“So what happens when you breathe this way is you stress your body out. […] You control your stress to a specific amount of time so that, for the rest of the day, you can chill out. So that is probably why Wim Hof’s method works so well.”

- James Nestor

Tomorrow is Wim Hof’s birthday. In that spirit, here’s a quick 2.5 minute clip of James Nestor explaining how the WHM works.

Enjoy!

Related Quote: “I’m not afraid of death, I’m afraid not to have lived fully.” - Wim Hof

4. We Are All Living Nasal Breathers

“All living things on our planet undergo a unescapable and predictable daily change in their environment: Day becomes night. […] To cope with this predictable daily change in light and dark, almost every living organism has developed an internal timing system, or circadian clock.”

- Satchin Panda, PhD, The Circadian Code

In The Circadian Code, we learn that, try as we might, we cannot override our circadian rhythm. Evolution programmed it into us. Trying to fight it with more coffee (talking to myself here) will only hurt us in the long run. We’re much better off aligning with it to achieve our best health outcomes.

This reminded me of a seemingly unrelated, yet similar concept: we’re all nasal breathers.  We can optimize our diets, exercise, and so on, but if we don’t breathe how evolution designed us to—through our nose—we’ll never reach our full health potential.

How To Be a Straight-A Breathing Student, and Why Diabetics “Get It”

 
 

Listen to this post in 5 min 51 sec:

 

Yesterday was 4-11.

Yesterday was World Breathing Day.

Yesterday was also my birthday.

It’s almost as if it was meant to be this week…

Alright, here are 4 thoughts, 1 quote, and 1 answer for the week. Enjoy!

 
 
 
 

4 Thoughts

1. How To Be a Straight-A Breathing Student

One of my favorite stories is the “50 lbs = A” parable. I even kept a post-it of that phrase on my monitor during my post-doc. As it goes, a professor found that grading ceramics students based on quantity—50 lbs gets you an A—led to better quality than grading them on one “masterpiece.”

The moral of the story: Quantity leads to quality.

Quality is obviously essential to breathing. We do take more than 20,000 breaths per day, as it is. But, perhaps what’s more important is just starting and sticking to a consistent breathing practice.

So for breathing, we might say: Focused quantity leads to quality.

You might not begin with perfect diaphragmatic breathing, proper tongue placement, or proper volume. But with a consistent practice, you’ll naturally start noticing and improving these things.

So how about we write our own parable, where 50 breaths = A.

Or maybe just 5 breaths or 5 minutes. Regardless, it’s the focused, consistent quantity that counts. Here’s to becoming straight-A breathing students today.

Related: “If you want to master a habit, the key is to start with repetition, not perfection […] You just need to practice it.” - James Clear, Atomic Habits

2. Why the Power of Breathing is Actually Easy to Explain to People with Diabetes

Ask a diabetic what affects their blood sugar. They’ll either start laughing, or immediately blurt out “everything!”

So then, when you tell them that breathing literally impacts almost every bodily function, they’ll get it:

Everything affects my blood sugar. Breathing affects everything.

It just makes common sense for us diabetics to optimize it.

Related Quote: “Breathing isn’t everything. But, breathing impacts everything.” - David Bidler

3. This Breathing Exercise Can Calm You Down in a Few Minutes

“Many people find benefit, no one reports side effects, and it’s something that engages the patient in their recovery with actively doing something.”

- Cynthia Stonnington, Chair, Department of Psychiatry and Psychology, Mayo Clinic, Phoenix, AZ

Here is yet another excellent article from Vice: This Breathing Exercise Can Calm you Down in a Few Minutes. In it, we learn about the power of resonant breathing from Cynthia Stonnington (above) and gain invaluable insights from a pioneer in breath research, Patricia Gerbarg.

Enjoy the awesome read!

4. The Universal Structure of the Respiratory System

“There is something transcendent in the very structure of our respiratory system…Other examples of this configuration in nature abound—streaks of lightning converging into a single bolt only to diverge again as they approach the ground;

the tributaries of a riverbed unifying into one main waterway; the human body itself, branching from its trunk to arms and legs, then fingers and toes.

The lungs tap into something universal in their structure, maximizing uptake of the life force that surrounds all of us.”

- Michael J Stephen, MD, Breath Taking

Here's another gem from Breath Taking's prologue, reminding us just how remarkable, yet universal, the structure of our respiratory system is.
