1. Study: Prayer and Mantra Lead to ~5.5-6.0 Breaths a Minute

“Remark­ably, the regularity of breathing seen during recitation of the Ave Maria or of the mantra was similar to regu­larity during controlled breathing at 6/min, indicating that these methods could stabilise the respiratory rate as effectively as precisely timed control.”

- Effect of rosary prayer and yoga mantras on autonomic cardiovascular rhythms…

In this now somewhat famous study, reciting the Hail Mary prayer or a yoga mantra naturally led to a breath rate of almost exactly 5.5-6 breaths/min. Leading to the conclusion: “The rosary might be viewed as a health practice as well as a religious practice.” 👏

P.S. I released a Science 411 for this paper on Friday as part of my new Breath is Life Learning Center. You still have two days to get this & tons of wisdom for just $11/month or $110/year (27% off forever) 🙏

2. The Power of the PNS and How to Nourish It

“Parasympathetic activation is the normal resting state of your body, brain, and mind. If your SNS were surgically disconnected, you’d stay alive (though you wouldn’t be very useful in an emergency). If your PNS were disconnected, however, you’d stop breathing and soon die.”

- Rick Hanson, Ph.D., Budhha’s Brain

That’s crazy. And since our PNS is so vital, I think it’s safe to say we should nourish it every chance we get. So how do we do it?

Here are two (of several) exercises Dr. Hanson suggests:

  1. Diaphragmatic Breathing: Place a hand on your stomach and look down at it. Then, breathe slowly, and try to “breathe into your hand with real oomph, so that it travels back and forth half an inch or more with each breath.”

  2. Big Exhales: “Inhale as much as you can, hold that inhalation for a few seconds, and then exhale slowly while relaxing.”

Better yet, combine the two, and enjoy stimulating and nourishing your PNS a little more this week : )

3. The Healing Power of (different) Breaths

“Each breath form is taught for its own special healing purposes. Just as you use different exercises for different muscle groups, you gain more by using a variety of breathing practices that each has their own unique effects.”

- Richard Brown, MD, and Patricia Gerbarg, MD, The Healing Power of the Breath

Just an excellent reminder that one of the key healing powers of the breath is that we can use it in different ways for different outcomes.

We “gain more by using a variety of breathing practices that each has their own unique effects.” <— Let’s do that 👏

4. Are All Breathing Practices Holotropic?

Discussing the word “holotropic:”

“This composite word means literally ‘oriented toward wholeness’ or ‘moving toward wholeness’ (from the Greek holos = whole and trepein = moving toward or in the direction of something).”

- Stanislav & Christina Grof, Holotropic Breathwork

Based on that, I’d say we practice “holotropic” breathing—moving toward wholeness—every time we stop and breathe consciously.

So regardless of what methods we use, let’s all orient toward wholeness a little more, this week 🙏

P.S. I’m releasing a Book 411 on Holotropic Breathwork this Friday. Although it’s somewhat controversial to some, I absolutely loved the book (and its bold claims). I hope you’ll consider signing up to get it.

1. How to Hold Your Breath for 6 Hours (hint: you already do)

  • Let’s say you take an average of 15 breaths/min, or 21,600 per day.

  • Let’s also say, like me, you’re a decent (but not perfect) breather.

  • Thus, at the end of each of those 21,600 breaths, there’s a short pause.

  • For simplicity, let’s say that pause is 1-sec (sometimes shorter or longer).

  • That adds up to 21,600 seconds without breathing each day.

  • That’s a 6-hour breath hold each day.

  • That’s 1/4 of your day.

  • That’s 1/4 of your life.

  • That’s 🤯 🤯 🤯

P.S. This thought was inspired by this +1 on heart beats.

2. Ancient Wisdom meets Modern Science: Alternate Nostril Breathing and the Brain

“Idā, which is activated by directing the breath through the left nostril, is said to establish a calm, introspective awareness, and have a cooling effect. Pingalā, the more stimulating side, is heating and mobilizing, and is activated through right-nostril breathing. Alternating the breath through both nostrils is said to cultivate balance and equanimity.”

- Robin Rothenberg, Restoring Prana

A recent study published in Nature tested these ancient yogic claims using EEG. Short story: the yogis were basically right. Left-nostril breathing activates brain regions “associated with a more relaxed state and introspective thinking.”

The right-nostril results were less certain, but the practice did lead to “higher activity compared to left airway UNB in all frequency bands across the whole scalp except in posterior areas.”

Of course, there are always caveats and limitations. However, one thing seems pretty clear: Left-nostril breathing can be used to reach calm and introspective states anytime we need them. I use it all the time—I hope you will too.

3. More Time: Breathing Exercises Get More Enjoyable with Practice

“How you feel the first time you try a new form of exercise is not necessarily how you’ll feel after you gain more experience.  For many, exercise is an acquired pleasure.  The joys of an activity reveal themselves slowly as the body and brain adapt.”

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

And the exact same is true for breathing exercises.

Give them time (I suggest about a week) so your body and brain can adapt. The benefits will gradually reveal themselves, and you’ll soon look forward to, and even find bliss in, your practice.

4. The Long-Term Benefits of Breathing Exercises: Normalize Cortisol and Be Calmer

“The long-term effects of a daily breathing practice, just like those of a daily exercise routine, are even more pronounced. Preliminary studies have found that regularly practicing breathing exercises normalizes your level of cortisol, the ‘stress hormone.’ As a regular practice, breathing can recondition your body to a state of greater calm, helping it bounce back from stress more quickly and perhaps reducing reactivity in the face of challenges…you can use daily breathing exercises to prepare your nervous system to be resilient in the face of stressful events.”*

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

And once your body and brain adapt, here’s why it’s so important to stick with these breathing exercises. You can recondition your body & nervous system to be calmer, then watch the benefits aggregate and compound over time 🙏

1. A Shared Theme: Breathing is the Most Accessible Tool We Have

“Breath is a direct, easy, accessible, and rapid way to shape the state of the nervous system. … The way we breathe says a lot about the state of our body and the story we are living.”

- Deb Dana, The Polyvagal Theory in Therapy

This echoes so many of the thoughts shared here; that’s why I love it so much.

It’s incredibly inspiring to find common themes in books on happiness, health, strength, mindfulness, therapy, philosophy, and on & on. And one they all come back to is this: breathing is the most accessible tool we have for optimal living.

2. A New Definition of Shallow Breathing

“Shallow Work: Noncognitively demanding, logistical-style tasks, often performed while distracted. These efforts tend to not create much new value in the world and are easy to replicate.”

- Cal Newport, Deep Work

We used Cal’s Deep Work Hypothesis to generate the Deep Breath Hypothesis. Let’s use this one to create a new definition of Shallow Breathing:

Shallow Breathing: Noncognitively demanding, rapid-style breaths, often performed through the mouth. These breaths tend to not create much value in our bodies and are easy to habituate.

3. The 3 Breathing Exercises Tony Robbins Uses

I just finished up Tony Robbins’s (literally) massive new book, Life Force. The audiobook is 22 hrs 50 mins! For a book called “Life Force,” I didn’t expect it to take ~10 hours to get to anything about breathing…but I digress 😊

In any case, it was worth the wait. Here’s how Tony uses breathing:

Breathwalking: “For example, one breathing pattern entails inhaling for four seconds, holding your breath for four seconds, exhaling for four seconds, and holding your breath for four seconds. A segmented 4:4 pattern that you can continue for several minutes while you walk in order to boost your energy and mental clarity.”* (He said this breathwalking method was one of his first intros to breathing, but I’m not 100% sure this is exactly the pattern he uses now.)

Really (really) Slow Breathing: He uses a 1:4:2 ratio breath with an 8-sec inhale, 32-sec hold, and 16-sec exhale, 1-3x a day. “I utilize this strategy to train the body to fully oxygenate by holding the breath longer and exhaling twice as long as you inhale, in order to eliminate toxins and stimulate the lymph system. I found it an invaluable tool to enhance my energy, my state of mind, and my sense of well-being.”*

Energizing Breathwork: “I also use a more explosive breath when I'm tired and need to snap myself into a peak state right before getting on stage. I drink my water, do my breathing, and I'm ready to rock and roll.”* Not sure what method he uses, but it might be Bhastrika (or Wim Hof breathing).

4. All Life Sciences are Breath Sciences

If breath is life, then all life sciences are, in some way, breath sciences.

  • Heart science is in some way breath science.

  • Brain science is in some way breath science.

  • Physiology is in some way breath science.

  • Psychology is in some way breath science.

  • & on and on

If you study life, you study breath : )

1. The Best Breathing (and life) Advice I’ve Ever Read

After reviewing tons of scientific papers, reading books, taking classes, and on & on, here’s the best breathing advice I’ve ever read:

“All this is literary, over-simplified, but we breathe as best we can.” - Samuel Beckett

We’ll never fully understand it. They’ll be inconsistent results. New discoveries. Revised approaches. But it’s all “literary, over-simplified.”

So, we just “breathe as best we can” with what we know.

P.S. Want the best life advice? Replace “breathe” with “live.” 🙂

2. Happy Valentine’s Day: 14 Loving Quotes on the Breath-Heart Connection

1. “Happiness lies in your own heart. You only need to practice mindful breathing for a few seconds, and you'll be happy right away.”

- Thich Nhat Hanh

 

2. “You know that our breathing is the inhaling and exhaling of air. The organ which serves for this is the lungs which lie round the heart. Thus breathing is a natural way to the heart.”

- Nicephorus the Solitary

 3. “If you would foster a calm spirit, first regulate your breathing; for when that is under control, the heart will be at peace; but when breathing is spasmodic, then it will be troubled.”

- Kariba Ekken

Keep going…

3. Story Follows State: Change Your Breath to Change the Messages Sent to the Brain

“We live a story that originates in our on autonomic state, is sent through autonomic pathways from the body to the brain, and is then translated by the brain into the beliefs that guide our daily living. The mind narrates what the nervous system knows. Story follows state.”*

- Deb Dana, The Polyvagal Theory in Therapy

“The mind narrates what the nervous system knows.” <— 🤯

And the fastest way to access the nervous system? The breath.

Change your breath, change your state, change your mind, change your story.

4. What Does All of this Mean in Real Life?

“So what does this mean for us? We can use our breath whenever we experience a stressful event. […] It's the most accessible tool you have, and it's invisible. You can practice breathing for well-being no matter where you are without anyone noticing.”*

- Emma Seppälä, The Happiness Track

That’s a perfect description of what all this breathing education means in real life. Of course, it won’t fix everything, but it’s the most accessible tool we have.

Let’s make it our ally.

1. On Bruce Lee, “Methods,” and Becoming Mixed Breathing Artists

“The individual is of first importance, not the system. Remember that man created method and not that method created man, and do not strain yourself in twisting into someone’s preconceived pattern, which unquestionably would be appropriate for him, but not necessarily for you.”

- Bruce Lee, Striking Thoughts

I think we can safely say Bruce Lee would be against using any one breathing “method.” He didn’t even believe there were different forms of fighting.

In fact, many consider Lee to be the original Mixed Martial Artist. Let’s follow his lead and become the first Mixed Breathing Artists.

That means we become both methodical and flexible. We focus on science and self-expression. We don’t strain ourselves to fit into a specific method; instead, we use what’s appropriate for a given situation.

Here’s to using the mixed breathing arts to conquer life’s challenges, today.

***

Related Quote: “Any technique, however worthy and desirable, becomes a disease when the mind is obsessed with it.” - Bruce Lee

Another: “The more complicated and restricted the method, the lesser the opportunity for the expression of one’s original sense of freedom.” - Bruce Lee

2. What Full Lotus Can Teach Us About Breathing

“Years after I had mastered the full Lotus, another teacher walked by while I was sitting, tapped on my shoulder, and gestured toward my full Lotus: ‘That is the whole problem for you.’ ”

- Larry Rosenberg, Breath by Breath

This is one of my new favorite stories. Larry Rosenberg had a teacher who thought sitting in full Lotus was essential. So, he practiced diligently and deliberately for 10 years. Finally, he could sit comfortably in it.

Then, a few years later, a different teacher saw him sitting in Lotus and told him, “That is the whole problem for you.” What one teacher said was essential, another said was his problem. His Lotus was perfect; that wasn’t the issue. It was his obvious attachment to it.

The lesson for us is that we cannot attach ourselves to any one approach to breathing (just like Bruce Lee didn’t attach himself to any single martial art).

Of course, we need to be grounded in science-based principles. But remember to be open. The method you’ve perfected might be the one that’s holding you back the most.

3. From NPR: “Just Breathe: Body Has A Built-In Stress Reliever”

“The breath isn't something Western medicine should blow off. It's a powerful tool for influencing individual health and well-being. And the best part is all the ingredients are free and literally right under your nose.”

NPR published this article over a decade ago, but it’s still relevant today. Check it out to learn how we can use slow and fast breathing to stimulate the nervous system, and how slow breathing might change gene expression.

Enjoy the quick read!

4. The Beauty of Red Blood Cells

“These experiments revealed a novel activity of the RBC [red blood cell]: the RBC regulates its own principal function—that is, O2 delivery.”

- Extrapulmonary Effects of Inhaled Nitric Oxide

There are about 1 billion oxygen molecules on each of the trillions of red blood cells in your body. That’s a lot of oxygen. As the red blood cells circulate, they deliver this oxygen where it is needed most.

And as it turns out, the red blood cells themselves help regulate this process. Specifically, when they sense areas of low oxygen, they release a bioactive form of nitric oxide. This expands the vessels, which allows more blood flow and, ultimately, more oxygen delivery. It’s quite complex, and quite beautiful.

The Science of Presence, Beating Gravity, and How to Sleep Like a Pro

1. How to Sleep Like a Pro: Nose, 4-4-6-2, Repeat

“Breathe deeply and regularly…Try to breathe through your nose, keeping your mouth closed if at all possible. The more you breathe through your nose, the easier you will find it to breathe through your nose. In other words, use it or lose it.”

- Dr. Barbara Oakley and Olav Schewe, Learn Like a Pro

I didn’t expect to find anything about breathing in a book called “Learn Like a Pro,” which is geared mainly toward college students. But, to learn well, you need to sleep well. Enter: the power of the breath.

And their advice for falling asleep? Inhale for 4 sec, hold for 4 sec, exhale for 6 sec, hold for 2 sec. “This type of breathing balances both the oxygen and carbon dioxide levels in your body and allows you to relax more deeply.”

It’s just so awesome to see slow nasal breathing make its way into random places like this. If put into practice, these few sentences could change a student’s life forever. Simply amazing.

Here’s to sleeping (and learning) like a pro, tonight.

***

P.S. I’ve been having a little self-induced stress insomnia recently (such is life), so it was perfect timing for this passage.

2. Beating Gravity with Your Nose

“The results presented in this work provide evidence that the development of a substantial production of NO in the upper airways of humans may be an important part of our adaptation to life on two legs to ameliorate the influence of gravity on pulmonary blood flow distribution.”

- Nasal nitric oxide and regulation of human pulmonary blood flow in the upright position

Translation: Nasal nitric oxide might have been an evolutionary adaptation to counteract gravity, allowing us to sit and walk upright. 🤯

Gravity moves blood flow toward the base of the lungs. Nitric oxide, however, redistributes blood flow help better utilize the massive surface area of the lungs. This allows us to get more oxygen in the upright position.

So go take a walk, breathe through your nose, oxygenate your body, and enjoy this gift evolution has given us.

3. Psychology Today: “The Simplest Stress Management Skill”

“It may seem incredible that such a simple exercise can make a huge difference in a person’s ability to feel less stressed.”

- Dianne Grande, Ph.D., The Simplest Stress Management Skill

Of course, that “simple exercise” is slow deep breathing : )

This quick and excellent article touches on the vagus nerve and equal versus extended exhalations. It also provides some straightforward and practical guidelines for a “minimum effective dose” of slow breathing. Enjoy!

4. The Making of the Present Moment

“Your experience of the present moment is based on the activity of your nervous system at that moment. ”

- Rick Hanson, Ph.D., Neurodharma

We are always in the moment. As Howard Cohn says, “In truth, we are always present. We only imagine ourselves to be in one place or another.”

So what “presence” really refers to is experiencing our current moment. And as Dr. Hanson reminds us, our experience of any moment is just our nervous system at that moment. And the fastest way to access that? Our breath.

So experience your breath to experience presence. Or better yet, change your breath, change your nervous system, and use this science and physiology of presence to make your own moments.
