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… 😊

Reminder: A Good New Year Begins Now

Like a good inhale starts with a full exhale, or a good morning starts the night before, a good 2025 begins with how we end this year. So, if you want to start 2025 off strong, consider ending this year by becoming a Mixed Mindful Artist. You can do that by joining the Breath Learning Center. I’ve made it accessible, with options starting at just $5, because I believe the mixed mindful arts should be available to all who seek them. I hope you’ll join us!

4 THOUGHTS

1. Learning to Live

“In the practice of meditation you become sensitive to the actual experience of living, to how things actually feel. You do not sit around developing sublime thoughts about living. You live…meditation, more than anything else, is learning to live.”

– Bhante Gunaratana, Mindfulness in Plain English

Here’s a wonderful reminder that meditation—and all our other contemplative practices—are not a means of escaping life. They are actually a way of learning to live, a way of becoming more “sensitive to the actual experience of living.” 👏

2. Nasal Stimulation and Altered Consciousness

“The NS [nasal stimulation] elicited an altered perception of the self and of the flowing of time, a high degree of inwardly-directed attention together with a diminished ability of controlling their own thoughts, which led to a general perception of being in an altered state of consciousness.”

- Nature Sci Rep (2018)

I shared about this study about a month ago, but I recently made a post explaining its fascinating results that I thought you might enjoy. Check it out on HHPF.

3. Three Random Breathing Thoughts

1. Breathing exercises don’t solve our problems—they change how we interpret our problems, which may be just as valuable.

2. The goal of a mindful breathing practice is better mindless breathing.

3. Start by starting; one minute is always better than none-minutes.

4. An Internal Jog

“Hearty laughter is a good way to jog internally without having to go outdoors.”

– Norman Cousins

That’s a great analogy and reminder to take a daily “internal jog” this week using the most therapeutic breathing exercise of all—laughter. No treadmills required 😊

1 Quote

“I believe I know the only cure, which is to make one’s center of life inside of one’s self, not selfishly or excludingly, but with a kind of unassailable serenity—to decorate one’s inner house so richly that one is content there, glad to welcome anyone who wants to come and stay, but happy all the same when one is inevitably alone.””
— Edith Wharton

A Clear Path?

“If the path before you is clear, you’re probably on someone else’s.”

– Joseph Campbell

This perfectly captures the essence of becoming a Mixed Mindful Artist. We don’t focus on one method that worked for someone else; instead, we find our own path, guided by timeless wisdom, modern science, and self intuition. So, if you’re ready to start clearing your own trail, get started today.

Build-a-Breath, How to Work with Emotions, and Carrying Great Power

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.

How Nasal Breathing is Imprinted on the Brain - And What it Means for You

 
LifeTooShort_JamesClear.png
 

It feels somewhat odd to send to write a post breathing right now. There are certainly bigger problems to worry about. But, I hope this can, at the very least, serve as a distraction. Stay healthy and stay safe!

 

It makes sense that our brains have regions that “light up” when we smell something. But, what about the airflow itself? If there was no odor, would we still see effects on the brain?

That was the question this week’s paper answered.

Activity Patterns Elicited by Airflow in the Olfactory Bulb and Their Possible Functions

(Click Here to Read Full Summary)

It took me two days to enter all of my notes on this one. I felt almost neglectful distilling everything into one page for the summary.

Using fMRI, the authors examined how nasal airflow stimulated the olfactory bulb of mice and compared it to that of odor stimulation. The main difference: Nasal airflow lights up broad regions of the olfactory bulb, whereas odor stimulation is more localized.

Interestingly, the intensity of the nasal breathing signal only changed with total airflow. For example, if they increased the breathing frequency, but reduced the volume, intensities remained relatively constant. But, if they increased frequency and volume, things “lit up” even more.

Why is all of this important for you? The olfactory bulb influences the limbic system, which influences emotions and the autonomic nervous system. Therefore, if nasal breathing is imprinted on your brain in the olfactory bulb, this helps explain how it can easily influence your emotional and physiological state.

If you have done any breathing practices, you have likely experienced this. Here, we see one reason why.

So, we can conclude: Breathe through your nose to change your brain, change your emotions, and change your physiological state. Simple, yet profound.

In good breath,
Nick
