4 THOUGHTS

1. Tickle Your Adrenals with this Therapeutic Breathing Exercise

“In the body, laughter serves an important purpose. It quite literally tickles the adrenals. The diaphragm is located just above the adrenal glands, which house our reactivity, our fear and anger, our apathy and hatred. When we laugh, we flex and release the diaphragm. This gives a light jiggle to the adrenals that I think of as a tickle. … In my experience, the adrenals are often quite relieved by the invitation to relax and let go.”

– Gladys McGarey, MD, The Well-Lived Life

​

This is your friendly reminder to laugh and “tickle your adrenals” today. Laughter is, after all, the most therapeutic breathing exercise 😊

2. Becoming More Human, Not Superhuman

“It’s very intuitive: If we breathe better…we can deliver more oxygen to our muscles and organs, including the heart and brain, and thus heighten our physical capacity. All we’re really doing is assisting the body in working the way it was meant to work in the first place.”

– Patrick McKeown, The Oxygen Advantage

That’s a great reminder that breathing (and other mind-body practices) are not hacks to boost our health to superhuman levels. They’re simply “assisting the body in working the way it was meant to work in the first place.”

We’re becoming more human, not superhuman.

3. A Mind-Blowing Study on Sleep: Is It All in Your Head?

Of course, sleep is critical to health, and if this study was performed over a long duration, its results would likely change. But this passage from Dr. Langer is an extraordinary reminder of the power of the mind:

“Our intervention was simple: We programmed a bedside clock to alter the amount of time that participants thought they had slept, irrespective of their actual sleep duration.

When the clock was sped up, such that people thought they had slept for eight hours but had slept only for five, their reaction times were quicker on an auditory psychomotor vigilance test as compared to their performance when knew they had five hours of sleep. Conversely, when people slept for eight hours but thought that they only slept for five, their performance was worse than when they had slept eight hours and thought they had slept eight hours. Clearly, our perceptions of how much we’ve slept, and not just the actual number of hours, matter.”

Here’s the link to the study. I highly encourage reading the first three sentences of the discussion 🤯

4. The Biggest Mistake in Breathing

The most common mistake in breathing is using the nose, lungs, and diaphragm, but not the heart.

4 THOUGHTS

1. Build-a-Breath: Breath Stages and the Nervous System

“Vagal activity is enhanced during the postinspiratory period and inhibited during the postexpiratory period.” - Kromenacker et al. (2018)

 

When I read this somewhat unassuming sentence, it actually led to a pretty big “aha moment” for me. It means: 

  • Inhalations: Sympathetic

  • Inhale-Pauses: Parasympathetic

  • Exhalations: Parasympathetic 

  • Exhale-Pauses: Sympathetic (I had never actually thought about this one and just assumed it was parasympathetic.)

Let’s apply this to a real-world example: the popular 4-7-8 breath. Using the above relationships, we see that 4 seconds are spent in sympathetic and 15 parasympathetic—no wonder it’s so relaxing.

With this information, you can now assemble and tailor a breath to meet your needs using a simple app like Breathe: iPhone & Android.

The power is yours…have fun with it 🙏

 

2. One Way to Stop Overbreathing: Mouth Tape at Night

“Taping the mouth at night ensures the benefits of good breathing during sleep, allowing you to fall asleep more quickly, stay asleep longer, and wake feeling energized.”

– Patrick McKeown, The Oxygen Advantage

And if that’s not enough, it’s also one way (among many changes we need to make) to train our bodies to breathe less in general.

As Patrick says, “Spending a guaranteed eight hours breathing through your nose while you sleep is an opportune way to reeducate your respiratory center to adjust to a more normal breathing volume.” 👏 👏 👏

***

P.S. If you want more amazing wisdom from The Oxygen Advantage, I just released a Book 411 summary on it in the Learning Center.

3. How to Work with the Root of Emotional Imbalances

“No matter how out of control we feel, how low our energy is, or how large our problems seem to loom, wind energy training is an effective intervention for all emotional imbalances. When we work with the breath, we work with the root of the problem.”

- Anyen Rinpoche & Allison Choying Zangmo, The Tibetan Yoga of Breath

I have nothing to add except to repeat that last sentence: “When we work with the breath, we work with the root of the problem.” 👏

4. A Tiny Thought On Why Breathing Helps Everything

Since no bodily function can occur without breathing, it just makes sense that breathing, in some way, influences every bodily function.

Why Breath Control Matters, -148°F, and Engaging Fully in Life

,

Listen Instead of Reading

If you enjoy listening, you can subscribe to the audio version on Spotify, Apple Podcasts, and Audible so you don’t even have to look at the email 😊

4 THOUGHTS

1. A Remarkable Fact About the Upper Airways (-148°F)

“…the upper respiratory tract is able to warm and saturate inspired air so that in climates as cold as minus 100°C [-148°F] air entering the alveoli has attained body temperature and is saturated with water vapor.” 

- Walker and Wells (1961)

My brain can’t fully grasp how remarkable that is over such a short distance…

Our airways are incredible.

2. Oral Posture and Nasal Breathing

“Try it for yourself: Open your mouth and place your tongue on your upper palate. Now try to breathe through your mouth. While it is possible to draw a wisp of air into the lungs, it will not feel right. It follows therefore that the tongue of a mouth breather will tend to rest on the floor of the mouth or suspended midway.”

– Patrick McKeown, The Oxygen Advantage

Patrick’s explanation here is perhaps the most commonsense reason for maintaining optimal oral posture: It promotes nasal breathing simply because breathing through your mouth is awkward when the tongue is against the roof of the mouth. 👏

3. Why Voluntary Breath Control Matters

“We can hold our breath, or breathe faster, or breathe slower, at any time, by choice. Why does this control matter? It matters because breathing is the link between our inner and outer experiences … It is also the link between the physical and emotional reactions we have to those experiences. In other words, what is happening within our bodies and minds is channeled through our breathing.”

- Anyen Rinpoche & Allison Choying Zangmo, The Tibetan Yoga of Breath

I have nothing to add except a few of these 🤯 🤯 🤯

4. A Neat Study on Slow Yogic Breathing and Vagal Stimulation

“These findings raise the possibility that mind-body techniques that use slow breathing at rest exert their breathing-related relaxation effects through vagal mechanisms.”

- Vagal Mediation of Low-Frequency Heart Rate Variability During Slow Yogic Breathing

This ingenious study separately blocked the parasympathetic and sympathetic nervous systems and then measured HRV during slow yogic breathing. By doing this, they conclusively found that increases in HRV were primarily due to increased vagal activity.

In other words, slow breathing is vagus nerve stimulation 👏

1. On & Off: The Stress-Reducing Effects of Fast Breathing


“Breathing really fast and heavy on purpose flips the vagal response the other way, shoving us into a stressed state. It teaches us to consciously access the autonomic nervous system and control it, to turn on heavy stress specifically so that we can turn it off and spend the rest of our days and nights relaxing and restoring, feeding and breeding.”

- James Nestor, Breath


Although I talk about slow breathing 99.9% of the time, this is an excellent description of the benefits of occasionally practicing fast breathing: We consciously turn on stress so we can then turn it off. 👏

2. Breathing for Happiness, Love, and Wisdom


Thought #1 reminded me of this amazing quote from Rick Hanson, Ph.D., in Buddha’s Brain:


“Happiness, love, and wisdom aren’t furthered by shutting down the SNS [sympathetic nervous system], but rather by keeping the autonomic nervous system as a whole in an optimal state of balance.”


So here’s to using our breath—our remote control to our nervous system—to achieve an optimal state of balance and find a little more happiness, love, and wisdom this week 🙏

3. The Breath of Life Influences Everything


“Chronic overbreathing leads to loss of health, poor fitness, and compromised performance and also contributes to many ailments including anxiety, asthma, fatigue, insomnia, heart problems, and even obesity. It may seem strange that such a disparate range of complaints can be caused by or worsened by overbreathing, but the breath of life influences literally every aspect of our health.”

– Patrick McKeown, The Oxygen Advantage

 

And fortunately, this is also why improving our breathing can help with so many issues—because “the breath of life influences literally every aspect of our health.” 👏

1. Slow Breathing Improves Cognition: A 2022 Study

“Finally, at the applied level, these findings may have implications for individuals looking for a quick and easy method to alter their executive functions, for example, to better execute cognitively demanding tasks in their jobs.”

- J. Psychophysiology (2022)

This recent study found that 15-min of slow breathing:

  • Improved attention control

  • Improved working memory

  • Increased cognitive flexibility

Take-home: slow breathing helps you plan, monitor, and execute your goals.

***

P.S. If you’re interested, there’s a new Science 411 for this one that goes through all the details.

2. Meditation, Yoga, and the Healing Touch of Prayer

Here’s a memorable passage from Breath, where James Nestor offers an eloquent summary of the benefits of slow breathing:

“In many ways, this resonant breathing offered the same benefits as meditation for people who didn't want to meditate. Or yoga for people who didn't like to get off the couch. It offered the healing touch of prayer for people who weren't religious.”  

 

Sounds good to me 🙏

***

P.S. Note that the key words are “in many ways”; not “in all ways.”  Breathing isn’t a one-to-one replacement for these other powerful health practices.  But, it is a nice option that covers many bases.

3. Patrick McKeown & the New Free OA App

Patrick McKeown and the Oxygen Advantage® team released a new app. It’s got a TON of guided breathing exercises and educational videos—and it’s all free!

1. The Famous 10-18% Nasal Breathing and Oxygenation Study

“We here show that arterial oxygenation is improved in healthy awake subjects during nasal breathing as compared with mouth breathing.”

- Lundberg et al. (1996)

Two take-homes from this oft-cited paper:

  • Nasal breathing increased tissue oxygenation by ~10% compared to mouth breathing in 6 of 8 healthy people.

  • Adding nasal air to a ventilator increased arterial oxygenation by ~18% in 6 of 6 mechanically ventilated people.

Deep dive of this paper:

This one was packed with fascinating results. If the take-home is all you need, stop there. But if you’re a serious breathing nerd, this one is a must-read/listen-to Science 411 (just released on Friday).

2. Use Your Diaphragm for Less Stress & Better Cognition

“Diaphragmatic breathing can directly lower cortisol levels, reducing the negative physiological responses to stress and improving cognitive function.”

- Patrick McKeown, The Breathing Cure

Sounds good to me. If we combine that with thought #1, we can also increase oxygenation while we’re at it 👏

3. Exercise Your Rich Inner Core for More Benefits (beyond abs or diaphragm)

“More and more, I became convinced that our bodies are wired to benefit from exercising not only our muscles but our rich inner, human core — our beliefs, values, thoughts, and feelings.”

- Herbert Benson, MD, Timeless Healing

What better way to exercise and express those than a daily self-care ritual? I like 20-30 min of morning breathing & gratitude, but anything you do to connect to your values, beliefs, and feelings will do.

Have fun exercising your rich inner core, this week 🙏

4. Equanimity

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.

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.

“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.

4 THOUGHTS

1. Is There Really “Dysfunctional” Breathing?

"Breathing is one of the body’s critical functions.  When its fundamental processes break down, the body will compensate, calling on structures such as the core muscles to help maintain respiration."

– Patrick McKeown, The Breathing Cure (pg. 152)

Breathing is the body’s most critical function. So as Patrick tells us, even if we do it incorrectly, the body will compensate by activating whatever muscles are needed to keep it going. Breathing takes precedence over everything.

So, we might say that breathing will always remain "functional" in that it will always do its main task of keeping us alive. But, it might be severely inefficient.

Thus, "dysfunctional" breathing is really just inefficient breathing.

This gives us two options. We can develop optimal breathing, which uses the nose and activates the diaphragm. Or, we can ignore our breathing and let the body compensate on its own, usually in ways that are detrimental to our health.

I say we choose option 1.

2. Diabetes, Oxidative Stress, and Slow Breathing

High blood sugars generate free radicals. These excess free radicals deplete antioxidants and ultimately cause oxidative stress. This negative feedback loop has been described as the "single unifying mechanism for diabetic complications."

To combat this, people with diabetes would ideally find a way to both reduce free radical production and increase antioxidant defenses. Slow breathing provides a natural and effective method of doing just this.

For example, slow diaphragmatic breathing reduces post-meal oxidative stress. It also reduces oxidative stress associated with intense, long-duration exercise. The hallmark paper on slow breathing & diabetes published in Nature even said:

"…our results lead to the hypothesis that slow breathing may exert some antioxidant effect, possibly via parasympathetic stimulation."

Taken together, slow breathing appears to be a simple and effective way to help with oxidative stress in diabetes. Quite amazing.

3. Apparently Slow Breathing Makes Food Taste Better

"Smooth, relatively slow breathing maximises delivery of the particles to the nose. Food smells and tastes better if you take your time."

- Vice, Apparently Slow Breathing
Makes Food Taste Better

This was a fun read from Vice. At first, I thought it seemed a bit silly. But the study was originally published in PNAS, so maybe there’s something to it?

If we pair this advice with Ch. 7 of Breath, we might say that to enjoy a meal, breathe slowly and chew more. I’m constantly working on the chew more part…

Enjoy!

4. Take the Nose, Take the Life

"Ancient Egyptian cultures also recognized the importance of the breath, the evidence of which we see today in the many ancient statues that had their noses broken off but otherwise were left untouched. This defacement was no accident, but a deliberate act by conquering groups to take the life, in this case the breath of life, away from these icons."

- Michael J. Stephen, MD, Breath Taking

This is on the first page of the book. Although Dr. Stephen never mentions the power of the nose again, it’s a rather remarkable statement that emphasizes just how important the breath (and nose) were to ancient cultures.

The Breathing 411 - Understand This, and You Will Understand Breathing

 

Happy Monday. I hope you enjoy this edition with a cup of coffee : )

Enjoy 4 thoughts, 1 quote, and 1 answer (like "Jeopardy") related to breathing.

 
 
 
 

4 THOUGHTS

1. Understand This, and You Will Understand Breathing

Breathing information is often contradictory:

  • Wim Hof tells you to breathe more oxygen.
    Patrick McKeown tells you to breathe less.

  • Oxygen is your body’s most important energy source.
    But the exhale is the most important part of the breath.

  • You need to teach yourself to tolerate higher levels of carbon dioxide.
    Carbon dioxide also causes fear in people who literally can’t feel fear.

  • Lung capacity determines longevity.
    But you also shouldn’t take big breaths.

  • And on & on

To understand breathing, you must accept that all of these are right, and all of them are wrong. It depends on the circumstance.

Despite its simplicity, breathing is one of the most complex functions in the human body. Blanket statements on "right or wrong" simply cannot be made without context. We must embrace the contradictions.

2. Should You Be Breathing Even Slower?

A study published in 2006 found that resonance frequency was inversely correlated with height. That is, the taller you are, the slower you need to breathe to synchronize your heart rate, breathing rate, and autonomic nervous system.

In their excellent book, The Healing Power of the Breath, Richard Brown and Patricia Gerbarg give this specific recommendation: "For people who are over six feet tall, the ideal resonant rate is three to three and a half breaths per minute."

So, if you’re over six feet tall, you might find that breathing slower than the typical recommendation of 5-6 breaths per minute works better for you. I fall into that category, and I’ve found 3 - 3.5 breaths per minute (currently 7 sec inhale, 11 sec exhale) to be my sweet spot.

3. What is Hyperventilation?

"Respiratory alkalosis is caused by hyperventilation or a respiratory rate in excess of that needed to maintain normal PCO2." - Essentials of Pathophysiology, pg. 205

"Hyperventilation is a term that describes breathing beyond that which is required to meet the metabolic needs of the body as reflected in the production of carbon dioxide." - Respiratory Physiology, pg. 128

Here are two different textbook definitions of hyperventilation. It’s actually pretty straightforward. And, as you can see, it doesn’t involve huffing and puffing. Thus, we can hyperventilate without even knowing it.

Two easy ways to check if you are overbreathing are the BOLT score and the CO2 Tolerance Test.

Two easy ways to fix it are to breathe through your nose and make your breathing quiet while at rest.

Thanks to 411 reader W.H. for inspiring this thought.

4. Is Breathing Woo-Woo?

It fascinates me that breathing, your body’s most important function, has kind of a "woo-woo" reputation. It shouldn’t. There is a mountain of scientific evidence showing its efficacy for health and wellness. For example, I have reviewed over 80 scientific papers, and HHPF seems to post a new one every day.

But you actually don’t need any of the science. Here is the quickest way to determine for yourself:

Hold your breath.

I think you will agree "breathing" isn’t woo-woo after only a few seconds.

Thanks to fellow breathing nerd R. vdC. for inspiring this thought.

Question: What is sleep-disordered breathing?

 
 

The importance of tongue placement for breathing and stability

Hi everyone,

This week, I want to share a key takeaway from the Oxygen Advantage (OA) teacher training I attended a couple weeks ago.

Patrick McKeown (the founder of OA) is a wealth of knowledge. He’s been researching, applying, and teaching about breathing for nearly 20 years. It’s always an honor to learn from him.

Although I learned a ton, there was one thing that stood out this time: the tongue.

Your tongue should rest on the roof of your mouth, which will open up your airways. If your tongue rests down, it will restrict your breathing.

This is especially important during sleep. But, the only way to keep your tongue on the roof of your mouth during sleep is to make it a habit during the day. (I’m now trying to keep my tongue on the roof of the mouth as much as possible.)

However, knowing this science of tongue placement didn’t actually make me interested. What did was an exercise a physiologist led us through to demonstrate the importance of tongue placement for stability.

Here’s the exercise:

  1. Let your tongue fall off the roof of your mouth.

  2. Now, let your head fall back and look up at the ceiling.

  3. Repeat, but with your tongue pressed against the roof of your mouth.

You should feel more head and neck stability when your tongue is pressed against the roof of your mouth. The physiologist explained how this stabilizes the neck and spine, but most of it was over my head. I just know it worked.

Some others in class noticed that their breathing was significantly easier when their tongue was on the roof of their mouth.

With that in mind, try noticing where your tongue rests throughout the day. Try keeping it pressed against the roof of your mouth. This will help your breathing and stability.

In good breath,
Nick

P.S. One more picture from the training. They say you should never meet your idols, but Patrick (right) never disappoints. In addition to all of his knowledge, he’s just genuinely a nice guy. It was awesome to learn from him again.
