4 THOUGHTS

1. The “Common Currency” of Breath, Brain, and Mind

“The synchronization between respiration and slow neural activity is likely key to understanding the brain-physiology relationship. Higher degrees of coupling between respiration and brain activity likely manifest as the inverse of symptoms of panic disorder (e.g., relaxation, greater attention, and more measured thoughts). Slow rhythms thus provide a link and shared feature of respiration, neural, and mental activity serving as their ‘common currency’.

From Lung to Brain (2023)

How neat? Speed acts as a “common currency” that the breath, brain, and mind accept. This means when we slow our breathing, the brain and mind accept that as payment and slow down in return. The result is relaxation, better attention, and calmer thoughts 👏

2. An Overlooked Breathing Exercise

“We breathe, most importantly, to bring oxygen from the atmosphere into our bodies and to release carbon dioxide in return. Another crucial aspect of the breath, and one that is rarely discussed, is that it gives us our voice. Breathing generates speech, a fundamental element of our experience as human beings.”

– Michael J Stephen, MD, Breath Taking

Here’s an obvious yet often overlooked (for me, at least 😊) reminder that speaking is, at its core, a “breathing exercise.” This means that if we become conscious of what and how we speak, our speech can become an integral part of our practice, providing endless chances to use breathing and mindfulness to support the people we want to be.

3. Three of the Bests

1. The best healing breathing exercise? Laughter.

2. The easiest form of meditation? Laughter.

3. The purest, most universal, and most natural way to mindfulness? Laughter.

4. Move to Be Still

“We need to move to be still, and only from that place of stillness can we move well.”

– Caroline Williams, Move

Here’s a wonderful reminder that movement is critical to our breathing and meditation practices. They are two sides of the same coin: “We need to move to be still, and only from that place of stillness can we move well.” 👏

Whole-Brain Breathing, Nexus Point, and Life is Far Too Important

4 THOUGHTS

1. A Nasal Nexus Point

“That point at the tip of the nostril can be viewed as a sort of a window between the inner and outer worlds. It is a nexus point and energy transfer spot where stuff from the outside world moves in and becomes a part of what we call “me,” and where a part of “me” flows forth to merge with the outside world. There are lessons to be learned here about self-identity and how we form it.”

– Bhante Gunaratana, Mindfulness in Plain English

One of those lessons is that we are not separate from the world around us but are (quite literally) connected to it: “We” absorb pieces of “it,” and “it” absorbs pieces of “us.” The breath just reminds us that the boundary between “we” and “it” is somewhat of an illusion 👏

2. Breathing Modulates the Whole Brain

“We, therefore, propose that an individual’s respiratory rhythm serves a fundamental, intrinsic role that modulates the topography and dynamics of the whole brain. Going beyond respiration-brain coupling, this opens the door for the application of respiration as a therapeutic technique in mental disorders.

Neuroscience Bulletin (2023)

Our breathing might serve “a fundamental, intrinsic role that modulates the topography and dynamics of the whole brain.” How cool is that?

3. Three Random Breathing Thoughts

1. Slow breathing is air appreciation. Fast breathing is air intoxication. And breath holding is air imagination.

2. Breathing is more an expression of our life force than merely our connection to it.

3. With time, breath awareness naturally becomes gratitude for living.

4. Life is Far Too Important

“Life is far too important to be taken seriously.”

– Attributed to Oscar Wilde

Or if you prefer this version from Eckhart Tolle: “Life is not as serious as the mind makes it out to be.” Both are perfect reminders to smile and laugh at ourselves often this week 😊

P.S. Basic human needs:

The Generalist Approach

While I love just about everything about breathing and meditation, there’s one thing I feel could use more balance: Specialization.

Specializing to become “the best at this” or “the go-to person for that” certainly has its place and value. But for real-life, complex, messy humans (not speaking from experience or anything 😂), blending and adapting principles from a variety of practices, sciences, and traditions often works best.

This is the art of being a generalist, or what I playfully call being a “Mixed Mindful Artist.”

If you’re looking to build a truly beneficial personal practice or have a broader impact on those you teach, the generalist approach of becoming a mixed mindful artist might resonate with you.

4 THOUGHTS

1. A Miniature Model of Life

“When we truly observe the breath, we are automatically placed in the present. We are pulled out of the morass of mental images and into a bare experience of the here and now. In this sense, breath is a living slice of reality. A mindful observation of such a miniature model of life itself leads to insights that are broadly applicable to the rest of our experience.

– Bhante Gunaratana, Mindfulness in Plain English

Yep, that sums it up perfectly. I have nothing else to add but several of these 👏👏👏

2. Breath-Brain: Entire Fields are Dedicated to This

“The brain’s metabolic-energetic coupling to respiration is at odds with how neuroscientists methodologically treat respiration. Respiration-related neural activity is typically considered noise, and entire fields are dedicated to stripping it from brain data.”

Neuroscience Bulletin (2023)

The breath’s influence on the brain is so pervasive that “entire fields are dedicated to stripping it from brain data.” How crazy is that? 🤯

It’s a powerful reminder that, although we often talk about the breath’s impact on the nervous system, its effects on the brain may be the most profound (yet least appreciated) of all…

3. Three Random Breathing Thoughts

1. Shining your attention on your breath is like a dimmer switch: even if it’s not all the way up, it will still help you see better.

2. Scientific studies of breathing are timely and indispensable; personal experience with the breath is timeless and irreplaceable.

3. Equanimity is when the breather realizes they are the breath.

4. Few Persons Realize

“Few persons realize that health actually varies according to the amount of laughter.”

– James J. Walsh, MD, PhD

Here is our weekly reminder to laugh. It is, after all, the best “breathing exercise” around… 😊

Exciting News: A New Breathing Gas Discovered

 

Happy Monday. There was a breakthrough in breathing research over the past few weeks: A new breathing gas has been discovered. I hope the extra hour of sleep you got this weekend will help this exciting news sink in even deeper.

OK, let’s get to it. Here are 4 thoughts, 1 quote, and 1 answer for you to think about as we begin November.

 
 

 
 

4 THOUGHTS

1. A New Breathing Gas Discovered

"Thus, H2S [hydrogen sulfide] produced by CBS surely has a crucial role in maintaining eupneic-pattern respiration."

- Nature, Communications Biology

Hydrogen sulfide. It’s toxic, and it’s what gives rotten eggs their rotten smell. It also helps maintain our breathing.

A study published in Nature: Communications Biology on October 16, 2020, found that a small amount of hydrogen sulfide is critical to maintaining normal breathing. It does this through modification of the neural connections in the region of the brain that controls breathing.

When hydrogen sulfide production was stopped in rats, normal breathing turned to gasping, implying that it is vital to maintaining rhythmic breathing.

From a practical perspective, I’m not sure what this means yet. At a minimum, breathing now appears to be a four-gas system: oxygen, carbon dioxide, nitric oxide, and hydrogen sulfide.

We’ve found ways to breathe to optimize the first three. However, it’s not yet clear if the way we breathe (or do anything else, for that matter) can influence hydrogen sulfide.

In any case, as a fellow breathing nerd, I hope you find this as fascinating and humbling as I did. Here’s to the joy of never-ending learning.

P.S. Here’s a short summary of these findings from ScienceDaily.

2. The Single Most Important Part of the Breath

"Interestingly, Törnberg et al. recently showed that more NO is released from the nasal passages during nasal inhalation compared with exhalation." - Lundberg et al. (2008)

Here is yet another reason why inhaling through your nose might be the single most important part of breathing: nitric oxide (NO) production is much greater during inhalation than exhalation.

Here’s the finding from the paper mentioned above: "There was a marked flow dependency of nasal NO output, with the highest levels observed during inhalation at flows similar to those seen during normal breathing." - Törnberg et al. (2002)

In hindsight, this makes complete sense. NO helps protect our lungs from inhaled pathogens and it redistributes blood flow in the lungs. So, of course our bodies would maximize it on the inhale. But it wasn’t until I read these two papers that it made sense to me.

"The obvious is that which is never seen until someone expresses it simply.” - Kahlil Gibran

3. What Focusing on the Breath Does to Your Brain

"Conversely, it may be possible to reduce fear and anxiety by slowing down our breath." - Greater Good, UC Berkeley

Here is a quick-reading article, packed full of excellent information, from The Greater Good Science Center at UC Berkeley. Anytime you see a headline like "Managing stress: Is it all in the breath?" you know it’s going to be a good read. Enjoy!

4. Sleep Scientists Call for the Elimination of Daylight Saving Time

"It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time."

- Journal of Clinical Sleep Medicine

I hope you all enjoyed the extra hour of sleep you got this weekend. The world’s leading sleep scientists say your body will function better, and they suggest we keep it this way (Standard Time) forever.

The above article is pretty short. But if you’re interested, here’s an even more concise summary, along with a rather impressive list of organizations that support the permanent change to Standard Time.

Because nasal breathing at night changed my life, I am endlessly fascinated with sleep. So I hope we all enjoy the next few months of better sleep and better optimization of our body's wake-light cycles.
