4 THOUGHTS

1. My New Favorite Signs of Progress

I look for changes in character and conduct. How selfless can you be? Can you restrain your senses when necessary? Can you go against your self-will when it benefits those around you? How long is your span of attention? These are the signs of progress in meditation.

– Eknath Easwaran, Passage Meditation

Of course, there are many different signs of progress in meditation (and breathing and mindfulness), but these are my new favorites 😊. They offer a simple yet powerful way to assess whether these practices are truly changing our lives.

2. Majoring in the Minor

“That’s when I learned that people have a habit of looking for the next big thing when they haven’t spent any time mastering the simple thing in front of them….A lot of you are missing the forest for the trees. You’re majoring in the minor. You’re getting in the weeds.”

– Arnold Schwarzenegger

Got any areas of your practice where you’re “majoring in the minor?” (Guilty here 🤚) Let’s use this as a reminder to master the simple tools in front of us—things like slow breathing, meditation, and mindfulness—before we go looking for the next big thing.

3. Three Reminders to Breathe Nasally

1. “The nose is the silent warrior: the gatekeeper of our bodies, pharmacist to our minds, and weather vane to our emotions.”- James Nestor

2. “Nasal stimulation represents the fundamental link between slow breathing techniques, brain and autonomic activities and psychological/behavioral outputs.” - Frontiers (2018)

3. “Obsessed with notions of health, he was fascinated by his breathing. In fact, Kant developed a technique of breathing solely through his nose—250 years before scientists recognized the role of nasal breathing for good health. Kant was so determined to breathe only through his nose that he refused to walk with a companion, fearful that conversation might inadvertently make him inhale through his mouth. Kant lived to just short of his eightieth birthday, a phenomenal age in 1804.” - Annabel Streets

4. Belly Laughing as Good as Crunches

“Break into a full belly laugh and you hit two pillars of stress control in one go. A recent study found that laughing really hard provides a better core workout than crunches.

– Caroline Williams, Move

We already know that laughter significantly reduces cortisol, but here we learn it might be as effective—or even better—than crunches for our core. Let’s use that as our friendly reminder to laugh this week to support both our physical and mental health 😊

Humor, How to Live Well, and the First Step Toward Self-Regulation

4 THOUGHTS

1. A Humorous Breathing & Mindfulness Practice

“I think the next best thing to solving a problem is finding some humor in it.”

- Writer and cartoonist Frank A. Clark

Here’s a “breathing and mindfulness” practice to try:

  1. Use mindfulness to find humor in a problem.

  2. Use breathing to laugh at it (and yourself) 😊

2. How to Live Well: Loving Attention in the Breath

“Living well, therefore, is merely a game of learning how to steer our energy toward life. It requires us to direct our loving attention toward the pulse that ebbs and flows within us, finding the precise rhythm of how that energy moves and immersing ourselves in it. When we do so, life comes alive.”

- Gladys McGarey, MD, The Well-Lived Life

What better way to “direct our loving attention toward the pulse that ebbs and flows within us” than with conscious breathing?

As Jon Kabat-Zinn says, tuning into the breath “immediately anchors our awareness in the body, in a fundamental, rhythmic, flowing life process.” 👏

3. The First Step Toward Self-Regulation

“But one of the best reasons to breathe through our nose as a regular practice, and as a mindful practice, is that it helps us to slow and regulate our respiratory rate…This is the first step towards self-regulation.”

- Eddie Stern, Healing Through Breathing

The first step toward self-regulation: breathing primarily through our nose. This one step helps us slow down and regulate our breathing, which helps us slow down and regulate our mind and body 🙏

4. You Are Still Carrying Her

Here’s a Buddhist story (I found in Advice Not Given) of two monks crossing a river:

“The two men come upon a young woman who is having trouble getting to the opposite shore. One of the monks, despite his vows to never touch a woman, picks her up and deposits her on the other side of the water. As they continue on their way, the other monk, the one who has kept his vows and not touched her, can’t stop chastising his overly benevolent friend.

How could you do that?’ he asks. ‘You know touching a woman is against our vows. And you were holding her.

I put her down long ago,’ replies the first monk. ‘You are still carrying her.’”

Catch & Shoot, 20 or 50 Years, and Slow Breathing Doesn’t Work Now


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 😊



Reading Time: 1 min 49 sec

I hope the next 27’ish breaths are the most nourishing of your day.



4 THOUGHTS

1. Slow Breathing Doesn’t Work?

A paper recently published in Nature may seem to suggest that slow breathing doesn’t work over a “placebo.” However, when analyzed carefully, it actually showed that controlled, nasal, diaphragmatic breathing works wonderfully (whether it’s slow or not).

I created a 10-minute video breaking down the study for those breath nerds who are interested : ) Watch it here.

2. Take a Walk and Breathe Through Your Nose

“Walking is the perfect time to hone your breathing. So take a stroll—and breathe through your nose.”

- Annabel Streets, 52 Ways to Walk

Want to get even more benefits from walking (as if there aren’t enough already)? It’s simple: just breathe nasally. As Streets says:

“As you walk, close your mouth; relax the jaw, tongue, and face; and breathe slowly in through the nose and out through the mouth or nose. You'll find this more challenging as your pace picks up. But stay focused and you might—possibly—have fewer colds, more energy, and greater serenity.

Sounds good to me 🙏

3. Catch Before Shooting: The Power of Breath Awareness

“I once saw a player trying to shoot before he caught the ball; he was moving so fast that when he finally was able to reach for the ball, he hit it and of course it flew out of bounds. Well, why does that happen? It's because he wasn't in the present moment; he wasn't in the flow.”

- George Mumford, The Mindful Athlete

This same thing happens in life. In high-stress situations, we often try to shoot before we’ve even caught the ball (guilty here). This is where breath awareness comes in.

When we come back to our breath before reacting to a stressor—even for one breath—it’s like catching the ball before we shoot. Just that simple act allows us to make a better play going forward.

4. Two Choices: 20 or 50 Years?

“A disciple asks a Zen master: ‘How long does it take to be able to experience Awakening?’ ‘Maybe 20 years,’ answers the master. ‘And if I am in a hurry?’ asks the disciple again. ‘In that case, it is 50 years,’ concludes the master.”

- Steven Laureys, MD, The No-Nonsense Meditation Book

This passage made me laugh out loud. It’s a perfect reminder that trying to hurry often takes more time.

How to Actually Increase Well-Being, Waves, and the Power of Breathwalk


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 😊


Reading Time: 1 min 23 sec

I hope the next 21ish breaths are the most nourishing of your day.



4 THOUGHTS

1. Without Wind, There Would Be No Waves

Imagine if we tried to understand ocean waves by studying the internal makeup of the water (without first examining the winds).

Yet we often try to understand the body by looking at all its intricate details (without first examining the breath).

Without winds, there would be no waves to study. Without breath, there would be no body to marvel.

2. The Well-Being Equation

In this eloquent equation (created by philosopher Arne Næss), “glow” refers to passion or fervor. It’s squared. This means a slight increase in glow will drown out increases in physical and mental pain.

It’s a nice reminder that, instead of always focusing on what’s bad, sometimes it’s better to simply create more good 🙏

3. There’s Something about Breathwalking

“There's something about walking to the rhythm of one's own breath, as if we can walk on and on, into the horizon and beyond.”

- Annabel Streets, 52 Ways to Walk

This book had an excellent chapter on the power of breathwalking (called “Afghan walking”). The above quote summarizes it nicely: By synchronizing our breath and steps, we feel we can walk forever.

Give it a try next time you walk around the office or to and from your car: Inhale 4 steps, exhale 4 steps (or whatever pace is comfortable for you). Simple yet extremely powerful.

4. One Could Spend a Lifetime

“Hence it is that one can spend decades, or even a lifetime, delving into the subtleties and implications of the process of breathing.”

Heroes, the Healing Power of Breathing, and the Key to Living Longer

4 THOUGHTS

1. A 2023 Review: Mindfulness Slightly Improves HbA1c in Diabetes

“Previous systematic reviews and meta-analyses have shown that mindfulness interventions are effective in improving glycemic control in people with type 2 diabetes. The reduction in HbA1c levels is approximately 0.3%”

- Hamasaki (2023), Medicines

A 0.3% improvement is not super meaningful. However, they also found that mindfulness helped reduce stress, anxiety, and depression in people with diabetes. Together, that’s still pretty neat 👏

2. But Mindfulness Helps in Less Quantifiable Ways, Too

For diabetes (or any condition), mindfulness helps in less quantifiable ways, too. Perhaps the most important is that, with increased awareness, we begin to notice variability in our symptoms. This gives us back some control over our condition:

“Put plainly, paying attention to variability helps us see that symptoms come and go, which helps us home in on the situations and circumstances that might contribute to these fluctuations so that we might exert some control over them. Having that kind of increased control gives rise to solutions that otherwise would not be forthcoming, as well as more optimism and less stress, which give rise to greater health in general.”

- Ellen Langer, Ph.D., The Mindful Body

Sounds good to me 👏👏👏

3. Nasal Breathing while Walking: The Key to Living Longer?

I feel obliged to share this amazing passage I read on Thursday morning in 52 Ways to Walk (such a good book, too):

“Obsessed with notions of health, he was fascinated by his breathing. In fact, Kant developed a technique of breathing solely through his nose—250 years before scientists recognized the role of nasal breathing for good health. Kant was so determined to breathe only through his nose that he refused to walk with a companion, fearful that conversation might inadvertently make him inhale through his mouth. Kant lived to just short of his eightieth birthday, a phenomenal age in 1804.”

4. The Healing Power of Breathing

The healing power of breathing is less about actual physical healing (although it can do that) and more about giving us back agency.

Controlling our breath shows us that we can control our mental and physical state, and this provides a sense of agency in all of life.

By controlling our breath, we become our own healers (and heroes).

10 Fun Thoughts, Meditation in a Bottle, and Whole-Life Slow Breathing

4 THOUGHTS


1. The Greatest Skill in Breathing (plus 9 more random thoughts)

The greatest skill in breathing (like in life) is knowing when to go with the flow, and when to deliberately change it.

Click here for 9 more random breathing thoughts and quotes.

2. “Meditation in a Bottle” (random product recommendation)

That’s a tagline of this relaxation shot by iCalm.

I stumbled upon it online, decided to buy some, and really loved them. I take one almost every afternoon now.

I have no affiliation with them…just thought it was a cool product and that maybe some of you would like it too 🙏

***

P.S. When I bought it, they sent an email questionnaire…I filled it out (it took less than a minute), and they sent me a few additional bottles for free. It might be random, but be on the lookout, just in case.

3. Whole-Life Slow Breathing

Regularly engaging in any kind of contemplative practice that slows down our breathing increases our vagal tone.

The best description I’ve read of why that’s important comes from Barbara Fredrickson, Ph.D., describing people with higher vagal tone:

“Physically, they regulate their internal bodily processes more efficiently, like their glucose levels and inflammation. Mentally, they’re better able to regulate their attention and emotions, even their behavior. Socially, they’re especially skillful in navigating interpersonal interactions and in forging positive connections with others.”

Sounds good to me. Perhaps we should call slow breathing “whole-life breathing” instead 😊

4. Nasal Breathing, Brain Oscillations, and Better Cognition

“A key implication of our data is that the nasal route of respiration offers an entry point to limbic brain areas for modulating cognitive function.”

- Zelano et al. (2016)

This study found that nasal breathing synchronizes oscillations in the piriform cortex, amygdala, and hippocampus (those last two regions are critical to emotions, memory, and behavior). This coherence leads to improved cognitive function compared to mouth breathing.

The take-home: Breathe through your nose as much as possible, especially when learning or in emotional situations, to improve brain coherence and cognitive functioning.

2. Seeing More Joy

Doing a deliberate slow nasal breathing practice first thing every morning is like putting on joy contacts to start your day.

3. A Good Case for Doing Your Practice in the Morning

“We each have our unique starting baseline—the level of stress arousal that we usually hover around through any typical day … Regardless of where we start from, the lower we can get our baseline stress arousal, the better—it means we’ll be much more able to tolerate the peaks of stressful events.”

- Elissa Epel, Ph.D., The Stress Prescription

To me, this passage presents a good case for doing our slow breathing (or whichever practice you do) first thing in the morning. By starting at a lower baseline, we’ll tolerate the day’s stressors better 👏

***

P.S. And if you choose slow nasal breathing, you’ll get the added bonus of seeing more joy 😊 (see Thought #2).

4. The Power of Breath Awareness

Dr. Amishi Jha discussing breath awareness in Peak Mind:

“[W]e use the breath for a couple of important reasons: It anchors us in the body. It allows us to experience the body sensations that are unfolding in real time as we breathe, in the here and now. … And finally, our breath is always with us. It’s the most natural built-in target for our attention that we can always return to.”

Put simply: The breath is the best way to be present with what is happening now.

4 THOUGHTS


1. The Passion Paradox

I love breathing and lose sleep thinking about it.

2. Two Unconnected (but highly related) Quotes to Contemplate

To know that the mind is the root of everything is to realize that we are ultimately responsible for both our own happiness and our own suffering. It is in our hands.” – Sogyal Rinpoche

“By controlling your breathing, you can use a voluntary mechanical behavior to make a profound change on your state of mind.” - Emma Seppälä, Ph.D.

3. An Easy Way to Change Your Brain & How You Feel

“Every time you take in the good, you build a little bit of neural structure. Doing this a few times a day—for months and even years—will gradually change your brain, and how you feel and act, in far-reaching ways.

– Rick Hanson, Ph.D., Buddha’s Brain

Here’s a simple way to put this idea into practice during your day: Take a couple of 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!”

***

P.S. I use this a lot.  Sometimes it feels too forced, and I don’t notice much of anything.  But sometimes, it profoundly shifts my mindset, making it worth it every time 🙏

4. Nasal Breathing Counteracts the Effects of Gravity

“In this work, we have demonstrated that nasal breathing counteracts the effects of gravity on pulmonary blood flow in the upright position by redistribution of blood to the nondependent lung regions.”

Sánchez Crespo et al. (2010)

I re-read this excellent paper and wanted to re-share this remarkable finding: Due to nitric oxide, nasal breathing redistributes blood flow from the bottom to the top of the lungs, countering gravity’s effects.

This *might* mean that nasal nitric oxide was an evolutionary adaption to lessen gravity’s effects, allowing us to walk upright 🤯

P.S. Check out the IG post for neat graphics.

4 THOUGHTS


1. More Joy: The Nose Should Be Considered Alongside the Vagus Nerve

“The emerging scenario strongly suggests that the effects of SNB [slow nasal breathing], beyond the relative contribution of vagal stimulation, are mainly ascribable to olfactory epithelium stimulation.”

Zaccaro et al. (2022), Neural Correlates of Non-ordinary States of Consciousness in Pranayama Practitioners: The Role of Slow Nasal Breathing

 

This was a challenging & super fun paper to read. Here is my two-sentence summary of it:

Slow nasal breathing has significantly different effects on the brain than slow mouth breathing, which results in less physical and psychological tension, less anxiety, more joy, and a relaxed yet fully aware altered state of consciousness. Nasal stimulation should be considered alongside vagal stimulation as a primary mechanism behind the benefits of slow breathing.

2. Upward Spirals in Your Life that Lift You

“In fact, science documents that positive emotions can set off upward spirals in your life, self-sustaining trajectories of growth that lift you up to become a better version of yourself.”

– Barbara Fredrickson, Ph.D., Love 2.0

 

This is the real power of the breath.  By using your practice to regularly elicit positive emotional states—a hallmark feature of slow nasal breathing—you set off upward spirals that “lift you up to become a better version of yourself.” 👏

3. A New “Long Beard” and the Buddha’s Advice

“Years ago, a wonderful Hindu teacher, Swami Chinmayananda, who taught me the Vedanta, said, ‘The longer the beard, the bigger the fake.’ And he, himself, had a beard that almost touched the floor!”

- Larry Rosenberg, Three Steps to Awakening

That makes me laugh. But, it also makes me think of how, in today’s society, our version of “long beards” are our credentials touching the floor: Ph.D., MD, Psy.D., D.O., and on and on : )

We can apply ancient wisdom to handle this modern scenario:

“[T]he Buddha tells us to take the counsel of the wise. We would be foolish to overlook their immeasurable knowledge and skills. But he also tells us to test the teachings in the fire of our own lives. Listen to them, weigh them, and investigate them.”

Sounds reasonable to me…almost as if that Buddha person knew a thing or two : )

4. Beating the Stress of a New Type of Gravity

Gravity is a stressor. But because there’s no way out of it, our bodies have adapted, and we don’t even notice it.

I think we should start treating the external stressors of our modern world (emails, social media, news headlines) like gravity. There’s basically no way out of them at this point.

What we need to do is adapt such that we hardly notice them.

Conscious slow breathing exercises are that adaptation. They’re always available to counter the weight of our new gravity.

- 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

Equanimity is when the breather realizes they are the breath.

1. Thirty Days to Better Sleep and Higher Vagal Tone

Taken together, our results suggest that slow-paced breathing performed before sleeping may enhance restorative processes at the cardiovascular level during sleep.

- Laborde et al. (2019), Journal of Clinical Medicine

Here’s another excellent study from Laborde & colleagues, with lots we could cover. But the take-home messages were that 15 min of slow breathing (6 breaths/min) before sleep for 30 days led to:

  • Significantly better subjective sleep quality

  • Significantly higher nighttime vagal tone (via HF-HRV)

  • Higher (but not significant) morning vagal tone

Not bad for just 15 minutes a night 👏

2. The Centering Breath (and 5 Breaths for Better Focus)

[B]reathe in for six seconds, hold that breath for two seconds, and then breathe out for seven seconds. When you modulate your breathing this way, you're controlling your state of arousal and corralling your body's natural response to stress.

- Dr. Jason Selk & Tom Bartow, Organize Tomorrow Today

Here’s a nice breath to try whenever you need to re-center. In for 6, hold for 2, exhale for 7. Even just one of those is enough to reset your focus.

3. Perfect Advice for Applying the Power of Breathing in Your Life

It’s not difficult to experience the psychological and social benefits of movement. … There’s no training formula you have to follow. There is no one path or prescription except to follow your own joy. If you’re looking for a guideline, it’s this: Move. Any kind, any amount, and any way that makes you happy. Move whatever parts of your body still move, with gratitude.” (my emphasis)

- Kelly McGonigal, Ph.D., The Joy of Movement

Although Dr. McGonigal is talking about movement, this is also the absolute perfect advice for breathing:

Breathe. Any kind, any amount, and in any way that makes you happy. And breathe with gratitude for this beautiful life we have, thanks to the breath.

4. Your Own Finely Crafted Breathing Program

Nose versus Mouth, 800000 and 73 days, and Our Best Weapon for Stress

1. A Simple Quip for Nose versus Mouth

Most of the time:

  • The nose is part of the respiratory system.

  • The mouth is part of the digestive system.

2. The True Power of the Breath: 800,000 and 73 Days

With eight hundred thousand new medical articles being published every year, by 2020 medical knowledge is estimated to double every seventy-three days.

Michael J Stephen, Breath Taking

Those numbers are insane. It’s basically impossible to keep up with science.

Fortunately, though, we know breathing (and sleep, exercise, meditation, etc.) has been used for millennia to improve mental and physical health.

Maybe we don’t know all the science, but that’s ok. We can just try it out, find what works for us, and enjoy the timeless (and timely) wisdom of the breath.

3. Two Steps to Get the Most of Your Breathwork

In The Art of Possibility, they have two steps for their practice of “giving way to passion.” I think they apply perfectly to breathing (or basketball, yoga, etc.):

1. The first step is to notice where you are holding back, and let go. Release those barriers of self that keep you separate and in control, and let the vital energy of passion surge through you, connecting you to all beyond.

2. The second step is to participate wholly. Allow yourself to be a channel to shape the stream of passion into a new expression for the world.

They sound a little idealistic and new-age, but that’s the point : )

4. Our Greatest Weapon Against Stress

Our greatest weapon against stress is our ability to choose one breath over another.

1. How Breathing Can Actually Change the World, in 3 Super Practical Steps

  • Step 1: Tape your mouth at night.

  • Step 2: Breathe nasally 90-95% of the day.

  • Step 3: Forget about the rest, and use your newfound energy from Steps 1 & 2 to help you do whatever you were put on this planet to do.

2. ANB Significantly Enhances Learning and Retention of New Motor Skills

Our results thus uncover for the first time the remarkable facilitatory effects of simple breathing practices on complex functions such as motor memory

- Deep Breathing Practice Facilitates Retention of Newly Learned Motor Skills

This 2016 study on alternate nostril breathing (ANB), published in Nature Scientific Reports, genuinely blew my mind. (See full review in Thought #3.)

Here’s what they did:

  • Participants learned a new motor skill.

  • A control group rested for 30 minutes.

  • A breathing group did 30-min of ANB.

  • Then, both groups were tested on the skill they had learned.

  • Both groups were also tested again 24-hours later.

The results showed that the ANB group significantly (it was almost ridiculous) improved the learning and retention of that skill:

  • They were significantly better at the 30-min mark.

  • They were significantly better at the 24-hour mark.

One 30-minute breathing session. One day of improved learning and retention.

4. Why We Breathe: Chemically and Spiritually

Our drive to breathe is regulated by the medulla oblongata … When pH decreases (becomes more acidic due to the increase in CO2), chemoreceptors in the medulla send out a signal for the body to breathe. This means that our carbon dioxide levels have to rise to a sufficiently high level for our brain and body to know that it is time to take the next breath.

- Inna Khazan, Ph.D.

It’s the perfect day to review why we breathe. So there’s the technical reason.

But breathing is a lot more than just gases. As Michael J Stephen, MD, tells us,

That oxygen, life, and lungs all came into our world in relatively close succession is no coincidence. Only with oxygen and some means of extracting it are all things possible—thinking, moving, eating, speaking, and loving. Life and the breath are synonymous.

So beyond chemistry, we ultimately breathe to live—to think, to move, to love. Breathing is, after all, what makes “all things possible.

1. Breathing Exercises Lower Inflammation and Change Gene Expression

In those who practice breathing exercises, levels of inflammatory proteins in the blood are significantly lower, especially under certain types of stress. Mobilizing the power of the breath has also been shown to turn on anti-inflammatory genes and turn off pro-inflammatory ones, including genes that regulate energy metabolism, insulin secretion, and even the part of our DNA that controls longevity.

- Michael J Stephen, MD, Breath Taking

I have nothing useful to add here, except, of course, one of these: 🤯

2. These Two Simple Rules Will Improve Your Breathing Forever

If I could give anyone any advice for everyday breathing, it’d be this:

  1. Breathe through your nose, especially during sleep.

  2. Make your breathing quiet.

You’ll get massive benefits with minimal effort using these two simple rules.

3. Timeless Healing: Slow Breathing + The Relaxation Response

To evoke the relaxation response, you need to follow only two basic steps. You need to repeat a word, sound, prayer, phrase, or muscular activity, and when common everyday thoughts intrude on your focus, you need to passively disregard them and return to your repetition.”*

- Herbert Benson, MD, Timeless Healing: The Power and Biology of Belief

It’s that simple. And the word or phrase? Dr. Benson says, “The choice of a focused repetition is up to the individual. If you’re a religious person, you can choose a prayer. If you’re a non-religious person, choose a secular focus.”*

I’ve been using it this week in my slow breathing practice. I inhale and then repeat “be the change” in my head while exhaling at a 5 breaths/min pace.

I’ve never been a big fan of mantras (and I’m still testing different ones), but I’ve genuinely enjoyed this. It’s straightforward and highly effective.

Give it a shot and see how you feel.

4. My Fake Words, and Breathing as the Anti-Harley-Davidson

Orfield Laboratories, run by Steven Orfield, is a small Twin Cities business that leverages the power of perception to help companies build better products. Harley-Davidson, for example, once hired Orfield to calculate the exact engine tone and decibel level that would give riders the impression that its motorcycles are powerful.”*

- Michael Easter, The Comfort Crisis

How crazy is that!? Harley-Davidson actually hired a company to ensure their engines gave “riders the impression that its motorcycles are powerful.

I think breathing is the anti-Harley-Davidson. You just relax and breathe. If it’s powerful, it’s powerful. If it’s not, it’s not. No fake impressions needed.

***

P.S. Although I take pride in this newsletter, sometimes I feel like Orfield Labs trying to make breathing sound perfect. It’s not. But it is truly powerful. So, don’t just read my words, try it out and feel its strength for yourself.

Alternate Nostril Breathing, 70% Exhales, and How to be "Happy Right Away"

 
 

Listen Instead of Reading


 
 
 

4 Thoughts


1. A Friendly Reminder to Exhale More than 70%

In Heart Breath Mind, Leah Lagos discusses a fascinating study where a group of people were instructed to only exhale about 70% of their air with each breath.

Here’s what happened:

After just 30 seconds of this subpar breathing, almost every subject reported a climb in unpleasant symptoms, including anxiety, dizziness, lightheadedness, and neck and shoulder tension.

The fix? Slow breathing with full exhalations. Give it a try and see for yourself.

2. An Ancient Breath and the Door to Heaven

By relying on the ‘door and the window’ (is meant) the nose as the door of heaven, and the mouth as the window of the earth.  It follows, then normally that the nose inhales and the mouth (should) exhale, and (this is) beneficial to breathing. ”

- The Primordial Breath, Volume I

This ancient approach was way ahead of science.

In fact, although the translation reads a bit choppy, we now know this method of nose-in/mouth-out can increase whole-body oxygenation by more than 10%.

Just don’t forget to exhale fully : )

***

P.S.The nose as the door of heaven”…I felt compelled to re-emphasize that 😊

3. Two Yogic Breathing Experts Describe the Balancing Act of Alternate Nostril Breathing

Ultimately, in the hatha yoga tradition, the intention with these nostril-specific practices is to establish balance between the two sides of the nervous system, so neither is dominant.

- Robin Rothenberg, Restoring Prāna

It sounds counterintuitive, but the reason we practice alternate nostril breathing (or ANB) is for balance, so neither side is dominant.

I love the analogy Eddie Stern uses: “You can think about breathing through alternate nostrils in the same way that we think about stretching both the right and the left sides of our bodies when we do yoga postures.

With ANB, we’re “stretching” different sides of the nervous system (since the right nostril is sympathetic and the left is parasympathetic). But the goal is the same: we train each side separately so they function better as a whole.

4. How to be “Happy Right Away”

The group that holds the pen between their teeth (which, you may notice, creates a sort of smile) are HAPPIER at the end of the experiment than people who hold the pen between their lips (which, you may notice, creates a sort-of frown).

- Brian Johnson, +1 On Smiling

This passage summarized a study showing that the act of smiling, even without a reason, makes you happier. And I think the same is true for slow breathing.

As Thich Nhat Hahn says beautifully,You only need to practice mindful breathing for a few seconds, and you'll be happy right away.

So let’s smile and breathe mindfully to be a little happier, today : )

How Breathing Helps You Get and Stay Frustrated (and why it’s a good thing)

 
 

Listen Instead of Reading


 
 
 

4 Thoughts


1. Why You Need to be Frustrated, and How Breathing Can Help

Long-haul creativity, Robinson believes, requires a low-level, near-constant sense of frustration. … It’s a constant, itchy dissatisfaction, a deep sense of what-if, and can-I-make-it-better, and the like.

- Steven Kotler, The Art of Impossible

A consistent breathing practice will improve your mental clarity and overall health. But it will also frustrate the hell out of you.

It’s so simple; why isn’t this taught everywhere? Wait, it’s free, and it literally helps everything?

Then, of course, your improved mental clarity will seep into everything you do, and you will get more frustrated with the world, in general. (Not that I’m speaking from personal experience or anything 😂)

But now we see it’s a good thing. We need a little frustration, a slight sense of dissatisfaction, a knowing that things could be better. It helps us sustain the creativity needed to deliver what the world needs.

And a regular breathing practice is the easiest way to get that itchy dissatisfaction.

So, please, go get a little more frustrated, and a little more creative, today : )

P.S. Kotler shares nine different ways for achieving long-haul creativity in the book. This was #5, but its unexpected nature made it stand out the most.

2. A Few Stand-Out Passages on the Importance of the Ancient Nose

As a general note, the teachings on wind energy training and Yantra yoga emphasize breathing through the nostrils during the entire practice session. Unless we are given specific, personal instruction by a master on how and when to breathe through the mouth, we should always breathe through the nose.

- The Tibetan Yoga of Breath

The nose is the heavenly door (while) the mouth is the earthly window. Therefore, inhale through your nose and use your mouth to exhale. Never do otherwise for breath would be in danger and illness would set in.

- The Primordial Breath, Volume I

"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."

4. A Little Bit of Tape goes a Long Way

I guess it goes to show that a little bit of tape can go a long way.

- 411 Reader

When you tape your mouth at night, you reap the benefits of nasal breathing for 7+ hours a night. This includes things like better oxygenation, optimal breathing volume, harnessing nitric oxide, and brainwave synchronization.

Ultimately, this leads to deeper and more restorative sleep.

And if you’re a diabetic, your improved sleep might lead to noticeably better insulin sensitivity, which happened for this reader.

4 Thoughts


1. Longer Exhalations are Naturally Relaxing

It's helpful to extend your exhalations because the ‘rest and digest’ parasympathetic nervous system handles exhaling while also slowing your heart rate. So, longer exhalations are naturally relaxing.

- Rick Hanson, Ph.D., Neurodharma

Just a friendly reminder that extending the exhalation is one of the fastest ways to naturally relax. That is all : )

***

2. How Breathing Might Help with Insulin Sensitivity

These observations demonstrate that hypoxia rapidly regulated the inhibition of the insulin signaling pathway […] During reoxygenation, the ability of insulin to stimulate phosphorylation of insulin receptor and signaling proteins was restored after 45 min.

Hypoxia Decreases Insulin Signaling Pathways in Adipocytes

Insulin resistance is a critical factor in diabetes and overall metabolic health. In this paper, we learn that low tissue oxygen (hypoxia) can trigger insulin resistance. Encouragingly, however, reoxygenation restored it.

This is one reason why optimal breathing is so essential for metabolic health, especially for people with diabetes. By practicing slow nasal breathing, we increase our blood and tissue oxygenation. This could potentially maintain, or even restore, insulin sensitivity.

Of course, there is no research showing that slow nasal breathing does this—no one is going to fund that study : ) But, given what we know about slow breathing, tissue oxygenation, and blood flow, it seems reasonable to hypothesize that it would help. I know have certainly noticed a difference.

3. “Role of respiration in mind-body practices: concepts from contemporary science and traditional yoga texts”

Traditional yoga texts also suggest a solution for the imbalance in prana, through slow, deep breathing. … The beneficial effects of deep breathing are supported by contemporary science.

- Telles et al. (2014), Frontiers in Psychiatry

I’ve shared a quote from this paper before, but if you haven’t read the full thing, it’s well worth it. It describes how modern science supports ancient yogic breathing, for example, how “Conventional physiology has found benefits of deep breathing supporting the importance given to regulating the breath in yoga.

Another interesting idea they mention is that breathing “acts as both a top-down and bottom-up mind-body practice.” It makes perfect sense, but I hadn’t thought about it that way.

Ancient Yogic Wisdom + Modern Science = A Fantastic Read

Enjoy!

4. Finding Comfort in Breathwalking

To take my mind off the discomfort, I settle into a respiratory rhythm. I take one step as I breathe in, then two steps as I breathe out. One step breathing in, two steps breathing out. Over and over, focusing only on the breath.

- Michael Easter, The Comfort Crisis

Easter spent more than a month in a remote region of Alaska. And this book that came out of it is incredible—a perfect blend of science and storytelling.

Of course, this part stood out to me : )

Easter is making a ridiculous walk back to camp with a ton of weight. He naturally settles into his breath, and this gives him comfort and endurance.

As he puts it, “There's science behind this. Brazilian researchers found that people who are able to detach from their emotions during exercise, for example, not thinking about or putting a negative valence on their burning legs and lungs, almost always perform better.

So aside from the mechanics and oxygenation, here’s another way in which breathwalking can be beneficial. It helps you detach from your emotions. As Easter tells us, you’ll “almost always perform better.” Sounds good to me.

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.

4. The Most Important Part of Your Breathing Practice

Whether you’re breathing for longevity, energy, relaxation, or any other reason, here’s the most important part of the practice: to practice.

Hey,

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.

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!

 
 

 
 

4 Thoughts


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.
