4 THOUGHTS

1. Carve a Canyon: How to Produce Meaningful Changes with Breathing

“Rather, I think the power of breathwork to change the function of the nervous system can be compared to the way water cuts a canyon through rock. It’s the constant stimulus, the constant pressure, that produces huge changes, so that what appears to be a very gentle force produces very large results.”

- Andrew Weil, MD, Breathing: The Master Key to Self Healing

This analogy is why I appreciate gentle and easy breathing exercises.

Of course, intense sessions can provide rapid transformations.

But one strong thunderstorm rarely carves a lasting canyon.

It’s the gentle, constant force of simple techniques, applied over years & years, that often produces the most meaningful change.

2. There’s Something in the Air (this is truly an incredible study)

In The Mindful Body, Ellen Langer, Ph.D., describes an incredible study. Participants were led into an empty room. Beforehand, one of three things had happened:

  1. Meditators had meditated for 45 minutes and then left.

  2. People had watched a stressful video for 45 minutes, then left.

  3. Or the room was just empty for 45 minutes.

Participants entering after the meditators or stressful video watchers found the room more appealing and enlivening <—that’s pretty neat.

But wildly, only the group entering after the meditators improved their reaction time in a mindfulness test.

As Dr. Langer summarized, “These mysterious results suggest that somehow our mindfulness leaves a residue in the air and as such may affect the mindfulness of others.” 🤯

3. What Sets Breath & Mindfulness Apart: They Empower You

Breathing and mindfulness for people (with diabetes) are different than most approaches.

Instead of focusing solely on blood sugar control and doing everything “perfect,” these practices empower you to reduce stress, improve mental and emotional health, and cultivate resilience.

The goal isn't perfect numbers; it's peace of mind and lifelong agency.

4. Experience Gratitude Right Now

I shared this breath last year, but we can never do it too much 😊

Take a few conscious breaths and think to yourself: “This is great! I have an abundance of the most valuable resource known to our species, and I don't even have to work that hard to get it.”

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!

It’s an incredible gift from someone who, after 20+ years, still loves sharing breathing with as many people as possible 🙏

Go check out the app and enjoy all of the free OA exercises.

4. Sixty Seconds of Joy

For every minute you practice conscious breathing you gain sixty seconds of joy.

***

P.S. This is a play on an Emerson quote I saw on Insight Timer: “For every minute you are angry you lose sixty seconds of happiness.”

1. How to Align Your Mental Posture to be More Cognitively Powerful

There is always a mental posture, an alignment for your mind, as well as for your physical body.

- Gurucharan Khalsa, PhD, and Yogi Bhajan, PhD, Breathwalk

Mental posture” <— I love that.

We know that when we consciously sit or stand up straight, we feel more confident and alert. But we can also align our mental posture (say, by meditating) to help us feel more cognitively powerful, too.

So let’s pick a focal point and spend a few minutes coming back to it over & over to align and strengthen our mental posture a little more, this week. 🙏

***

P.S. I took “mental posture” somewhat out of context from how the authors were using it because I just love the wording so much : )


2. Use Less: Hypometabolism, the Relaxation Response, and “Mental Posture”

A hallmark feature of the relaxation response is a significant decrease in the body’s oxygen consumption, or hypometabolism. … The body responds to techniques that elicit the relaxation response by downshifting your metabolism. By allowing your internal perpetual energy machine to ease off working so hard, much less fuel is needed to sustain the body in the hypo metabolic state characteristic of the relaxation response.”*

- Herbert Benson, MD, Timeless Healing


And when we practice mental posture for about 10 minutes, here’s one of the outcomes: we elicit the relaxation response. Our bodies use less energy, we feel at ease, and we set ourselves up for restoration and recovery.

As I mentioned a couple weeks ago, I’ve been combining this with my slow breathing practice. I inhale, and during the exhale come back to an internal mantra (mental posture 101). It’s simple and genuinely powerful.

Give it a shot and see how it feels to shift into a hypometabolic state 🧘‍♂️


3. Success is Recovery: “Accomplish More than You Ever Thought Possible”

Athletes put their bodies under stress at each training session and competition, but they are only as successful as the speed at which they recover physiologically. Your daily stresses may be different from those of an athlete, but the concept is the same. Your success is determined by the speed of your recovery. By tapping into your natural resilience through breathing and other calming exercises that activate the rest and digest part of your nervous system, you can learn to reduce stress and accomplish more than you ever thought possible.”* (my emphasis)

- Emma Seppälä, Ph.D., The Happiness Track

When you apply Thoughts #1 & 2 consistently, especially combined with slow breathing, you learn to “reduce stress and accomplish more than you ever thought possible.” Sounds good to me 😊

4. Breath is Life, Spirit, and a Divine Gift Bestowed Upon Us

If you look up the word “spirit” in the dictionary, you will find that it comes from the Latin, spirare, meaning “to breathe.” The inbreath is inspiration; the outbreath expiration. From these come all the associations of spirit with the breath of life, vital energy, consciousness, the soul, often framed as divine gifts bestowed upon us, and therefore as aspect of the holy, the numinous, the ineffable. In the deepest sense, the breath itself is the ultimate gift of spirit.

- Jon Kabat-Zinn, Ph.D., Wherever You Go There You Are


Just another (quite eloquent) reminder that breath is life & spirit.

Let’s use this divine gift that’s been bestowed upon us wisely. 🙏

The Breathing 4.1.1. - Breathing That Makes You Smarter

 

Happy Monday and welcome to another edition of "The Breathing 4.1.1."

Below, I share 4 thoughts, 1 quote, and 1 answer (think "Jeopardy"). Enjoy!

 
 

 
 

4 THOUGHTS

1. Why Increasing Your CO2 Tolerance Just Makes Sense

i. Carbon dioxide is your primary stimulus to breathe. When you feel breathless or air hunger, that is due to high levels of CO2, not low levels of oxygen.

ii. Carbon dioxide helps you use oxygen more efficiently via the Bohr effect.

Therefore, being able to tolerate more CO2 just makes sense. You’ll delay the onset of breathlessness while simultaneously improving oxygen delivery.

2. Should You Be Doing Breathing Exercises All Day?

Not in my opinion. The goal of all of this "breathing stuff" is to reset your breathing to healthy levels so you don’t have to think about it all the time.

3. Can Your Breathing Make You Smarter?

Nasal breathing synchronizes brainwave oscillations in the piriform cortex, amygdala, and hippocampus. This coherence improves cognitive function when compared to mouth breathing.

4. If You or Your Child Suffers from This Condition…

If you’re reading this, the adverse health effects of mouth breathing probably seem obvious to you by now. But maybe not everyone else.

That’s why it is always great to see an article about it in a more mainstream publication like ScienceDaily. The final paragraph is both wonderful and comical (without trying to be):

"At this time, many health care professionals are not aware of the health problems associated with mouth breathing. If you or your child suffers from this condition, speak with a health care professional who is knowledgeable about mouth breathing."

Nasal breathing synchronizes brain wave activity and improves cognitive function

such-that-cognitive.jpg

Last week, we discussed century-old ideas about nasal breathing and mental function. I said that current science is beginning to catch up. Here’s how.

Modern Science Supports 100 Year-Old Observations

A study published in 2016 in The Journal of Neuroscience showed that nasal breathing is intimately connected to brainwave oscillations, emotional recognition, and memory retrieval.

Intracranial EEG measurements showed that nasal breathing synchronizes brainwave oscillations in the olfactory bulb, the hippocampus, and the amygdala. When breathing was switched to the mouth, this coherence disappeared.

In a follow-on experiment, they showed participants pictures of faces expressing fear or surprise. They had to pick which one it was as fast as they could.

Not only did the nasal breathers outperform the mouth breathers, but they also found that responses were quickest during inhalation versus exhalation. The participants also had more accurate memory retrieval during nasal inhalation.

Taken together, their results indicate that nasal breathing acts to organize brainwave oscillations and improve cognitive functioning.

These results also help explain Guye’s theory about nasal breathing and mental function. That is, they support the quote “Shut your mouth and save your brain.

Breathing is More Than Just Gases

These results imply that breathing is about more than just about gases. Breathing acts to synchronize brain activity and enhance cognitive function…but only when performed through the nose.

In good breath,
Nick
