4 THOUGHTS

1. The Most Empirically Supported Way

“The most empirically supported way that contemplative practices confer their psychological and physiological benefits is by lowering threat arousal through shifting the autonomic nervous system to parasympathetic dominance via slowed and/or regulated breathing.

- Crosswell et al. (2024), Psychological Review

Of course, contemplative practices go beyond breathing, drawing upon mind and body to uniquely benefit each person who practices.

But, this is a powerful scientific statement. It reminds us that because breath is both our spirit—the essence of our being—and our direct connection to the nervous system, it plays a key role (intentionally or unintentionally) in all contemplative practice 🙏

2. Give Your Heart and Lungs a Vacation by Practicing This

“In other words, patience is not only a mental virtue; it is an asset even for physical health. I’m sure you are aware of the way your heart races when you get impatient. Perhaps you have noticed, too, that your breathing becomes faster and more shallow. Doesn’t it seem reasonable that if you can strengthen your patience to such a degree that other people’s behavior never upsets you, your heart, lungs, and nervous system will be on vacation?”

– Eknath Easwaran, Original Goodness

That does seem reasonable : ) Here’s to cultivating a little more patience so that we may give our hearts, lungs, and nervous systems a vacation every day 🙏

3. Movement

Physical activity moves your body.

A breath practice moves your spirit.

And reading timeless wisdom moves your soul.

They all need movement to stay energized and robust.

4. My Teacher is the Best

“One Zen student said, ‘My teacher is the best. He can go days without eating.’

The second said, ‘My teacher has so much self-control, he can go days without sleeping.’

The third said, ‘My teacher is so wise that he eats when he’s hungry and sleeps when he’s tired.’”

4 THOUGHTS

1. Nurturing Our Body and Soul’s Physiology

1. The way we nurture our body’s physiology is through breathing.

2. The way we nurture our soul’s physiology is through love.

Thus, we can perform a breath practice followed by loving-kindness meditation as a simple yet deeply restoring way to start each day 🙏

2. A Technical (yet elegant) Reminder of the Power of the Breath

“The parasympathetic and sympathetic systems are tonically active, with efferent pathways extending from the brainstem and hypothalamus to all major peripheral organs and afferent nerves from the lungs, airways, and heart, projecting to the brainstem and to the hypothalamus and higher order neural regions. Because of this anatomical connectivity, changes in breathing rate are quickly signaled to the brain, allowing the brain to interpret that the body is in a relaxed, calm state, and safe state.”

- Crosswell et al. 2024

Be sure to take advantage of this “anatomical connectivity” this week 🙏

P.S. Don’t forget to check out the Science 411 on this one too.

3. There is No Hedonic Adaptation to This

“You might have thought that when we more often experience awe in the wonders of life, those wonders lose their power. This is known as the law of hedonic adaptation, that certain pleasures…diminish with their increased occurrence. Not so with awe. The more we practice awe, the richer it gets.”

– Dacher Keltner, Awe: The New Science of…

“The more we practice awe, the richer it gets.” This excellent idea explains why daily practices like breathing, meditation, time in nature, or reading timeless wisdom never lose their potency.

Each of these brings awe, connecting us closer to our true selves, and there is no hedonic adaptation to that 🙏

4. A Great Zen Master Was Once Asked

“A great Zen master renowned for his wisdom was once asked, ‘What’s the most remarkable thing you’ve learned in all of your years of meditation and study?’ He answered, ‘The most remarkable thing is that we’re all going to die but we live each day as though it weren’t so.’”

4 THOUGHTS

1. The Mindful Artist

“The artist actively works to experience life slowly, and then to re-experience the same thing anew.”

– Rick Rubin, The Creative Act

I think this could also define someone living mindfully, a mindful artist, we might say, experiencing each breath anew. (Maybe not all day, every day, but at least during their morning practice 😊).

2. Smile Before Putting (and breathing)

“One tip I've shared with many golfers is a simple one: smile a little bit before each putt. Frowning is something your body does automatically when you've engaged your conscious mind to concentrate on a problem. Smiling tends to be something your body does when you're relaxed and happy and your subconscious brain is in control. Smiling can help putting. Try it and see.”

- Dr. Bob Rotella, How Champions Think​

For these same reasons, smiling before (or during) a slow, deep, nasal breath can also be helpful. Try it and see 🙏

3. A New 2024 Meta-Analysis on Slow Breathing

“In conclusion, the current meta-analysis showed that slow-paced breathing had significant immediate beneficial effects on SBP, HR and time-domain HRV (RMSSD and SDNN), but not on DBP or frequency-domain HRV. Slow-paced breathing also had a modest effect in reducing negative emotions, particularly perceived stress.”

- The Effect of Slow-Paced Breathing on Cardiovascular and Emotion Functions: A Meta-Analysis and Systematic Review

Nothing too shocking here, but my overall takeaway was: Slow breathing, at least in the short term, generally had positive effects on cardiovascular and emotional health. Check out the study for more.

4. A Life-Changing Exercise and Shift of Perspective

“The next time you find yourself doing something embarrassing, I encourage you to try to think about how it could be seen as funny. What about your mistake is humorous? What was surprising, silly, or just plain ridiculous? How would someone on the outside see it, and why might they laugh? You’ll be surprised by how often a humorous interpretation is available if you only go looking for it.”

- Gladys McGarey, MD, The Well-Lived Life

Last week, we discussed how laughing is the most therapeutic breathing exercise, tickling your adrenals and thus easing your heart.

Here, we learn a simple practice to help make humor part of our day. I’ve done it several times since reading it, and it’s truly life-changing.

4 THOUGHTS

1. Tickle Your Adrenals with this Therapeutic Breathing Exercise

“In the body, laughter serves an important purpose. It quite literally tickles the adrenals. The diaphragm is located just above the adrenal glands, which house our reactivity, our fear and anger, our apathy and hatred. When we laugh, we flex and release the diaphragm. This gives a light jiggle to the adrenals that I think of as a tickle. … In my experience, the adrenals are often quite relieved by the invitation to relax and let go.”

– Gladys McGarey, MD, The Well-Lived Life

This is your friendly reminder to laugh and “tickle your adrenals” today. Laughter is, after all, the most therapeutic breathing exercise 😊

2. Becoming More Human, Not Superhuman

“It’s very intuitive: If we breathe better…we can deliver more oxygen to our muscles and organs, including the heart and brain, and thus heighten our physical capacity. All we’re really doing is assisting the body in working the way it was meant to work in the first place.”

– Patrick McKeown, The Oxygen Advantage

That’s a great reminder that breathing (and other mind-body practices) are not hacks to boost our health to superhuman levels. They’re simply “assisting the body in working the way it was meant to work in the first place.”

We’re becoming more human, not superhuman.

3. A Mind-Blowing Study on Sleep: Is It All in Your Head?

Of course, sleep is critical to health, and if this study was performed over a long duration, its results would likely change. But this passage from Dr. Langer is an extraordinary reminder of the power of the mind:

“Our intervention was simple: We programmed a bedside clock to alter the amount of time that participants thought they had slept, irrespective of their actual sleep duration.

When the clock was sped up, such that people thought they had slept for eight hours but had slept only for five, their reaction times were quicker on an auditory psychomotor vigilance test as compared to their performance when knew they had five hours of sleep. Conversely, when people slept for eight hours but thought that they only slept for five, their performance was worse than when they had slept eight hours and thought they had slept eight hours. Clearly, our perceptions of how much we’ve slept, and not just the actual number of hours, matter.

Here’s the link to the study. I highly encourage reading the first three sentences of the discussion 🤯

4. The Biggest Mistake in Breathing

The most common mistake in breathing is using the nose, lungs, and diaphragm, but not the heart.

1. Another Excellent Quote on Breathing from Another Doctor

Last week, I shared a great quote from Andrew Weil, MD. Here’s another one, this time from Wayne Jonas, MD, in his outstanding book How Healing Works:

Breathing techniques and mobile apps can teach you to use your breath to self-calm. The breath triggers changes in the body's nervous system that help you better manage stress. Deep breathing techniques help reduce feelings of anxiety and stress by blunting the expression of genes turned on during stress

👏👏👏

2. A Different Perspective on How to Make Progress in Your Practice

Sometimes progress is just knowing when it’s time to switch things up.

Improvement can simply be trying new breathing exercises when it feels right.

3. Heart & Happiness: Strengthening Your Heart May Have Antidepressive Effects

Additionally, recent neurocardiology studies have revealed that the heart is capable of secreting feel-good chemicals like dopamine, oxytocin, and norepinephrine, all of which help to counteract feelings of depression. … This suggests that strengthening the heart through HRV-strengthening practices could possibly yield mild antidepressive effects.

- Leah Lagos, Psy.D., Heart Breath Mind

That’s insane. And here’s Dr. Lagos’s starting practice for strengthening our hearts: “The standard rate that works for most individuals is to inhale for 4 seconds and exhale for 6 seconds with no pause in between.” Sounds good 🙏

4. The Breath of Art

Art, after all, is about rearranging us, creating surprising juxtapositions, emotional openings, startling presences, flight paths to the eternal.

Adding ‘breath’ to great quotes is what I do best (yes, blatant plagiarism is my calling 😂). So, here it is:

Breathing is about rearranging us, creating surprising juxtapositions, emotional openings, startling presences, flight paths to the eternal.

1. Two Places to Put Your Breath

Put your breath where your mind wants to be.

For acting:

Put your breath where your heart wants to be.

P.S. This was inspired by Steven Pressfield’s more explicit saying : )

2. How do Slow Breathing Practices Reduce Pain? Focus & Safety

It’s all about attention, says anesthesiologist Sam Sharar ... If we focus on a painful sensation, it will increase our experience of that pain. But if we think about something else—something safe, pleasant, far away—the pain we feel is dimmed.

- Jo Marchant

Cure: A Journey into the Science of Mind over Body

Slow breathing practices have consistently been found to reduce pain. This passage helps explain how: They give us something to focus on. And more than that, they also make us feel safe, which could be even more helpful.

And although this is referring to physical pain, I think these same mechanisms help explain why it’s so beneficial for emotional distress, too.

3. Our Somewhat Unusual Breathing Patterns During Sleep

In 1984, an editorial review on breathing during sleep had conclusions that were somewhat surprising (and opposite of what I expected):

  • Our breathing rate is variable, especially during REM sleep (I anticipated it would be slow and steady)

  • Our breathing volume is reduced significantly (by as much as 16%)

  • We frequently experience hypoxia (low O2) and hypercapnia (high CO2)

I guess we could say: The more we sleep, the less we breathe, the more we heal, and the longer we live : )

4. Taste the Hidden Life of Breathing

There is a great difference between comprehending the knowledge of things and tasting the hidden life of them.

- Isaac Penington

The breath itself is hidden life.

The more we practice, the more we taste it.

Why 6 Breaths/Minute Improves Heart Health & Quality of Life in Diabetes

Slow breathing is a highly effective yet overlooked therapy for diabetes.

 

It profoundly changed my life with diabetes, leading me to spend the past 5 years trying to understand it and share it with others.

 

I’ve found that it’s not going to fix everything (of course).  It may not even impact your blood sugars.  But, without question, two things it will do are improve your heart health and your quality of life.

 

And it’s available anytime, anywhere (no pre-authorization required). 

 

I think it’s a no-brainer for better health, and I hope this article inspires you to give it a try.

 

 

What is Slow Breathing? (and why was 6 breaths/minute in the title?)

 

Slow breathing is broadly defined as breathing at a rate of less than 10 breaths per minute.  More specifically, it usually refers to breathing at a rate of about 4.5 to 7 breaths per minute.

 

And even more specifically, almost every study on slow breathing and diabetes has used 6 breaths per minute.  And they’ve found some pretty remarkable things.

 

But before we get to that, let’s take a quick look at the breath-heart connection.

 

 

Understanding the Breath-Heart Connection: Respiratory Sinus Arrhythmia and Heart Rate Variability

 

When we inhale, our heart rate increases.  When we exhale, it decreases (if you’d like more details, here’s a blog I wrote for ResBiotic that explains it fully).  This is known as respiratory sinus arrhythmia (RSA).

 

RSA is one of the underlying principles of heart rate variability (HRV).  Generally speaking, HRV is the beat-to-beat time variability of heart rate.  Research shows that higher HRV indicates a more balanced nervous system and better cardiovascular health.  For these reasons, higher HRV is associated with a better quality of life.

 

And it turns out that people with diabetes typically have worse HRV than non-diabetics.  (A negative side-effect of researching diabetes is that it reminds me of everything it adversely affects.  However, it’s also encouraging to find simple tools like breathing that can help (not fix) some of the problems).

 

 

HRV is Reduced in Diabetes

 

A 2018 meta-analysis found that patients with type-2 diabetes had significantly lower HRV than those without it.  Diabetics with chronic complications have even lower HRV

 

The lower HRV observed in people with diabetes is likely related to many negative aspects of the disease, such as chronic stress, inflammation, and increased oxidative stress. 

 

Perhaps unsurprisingly, low HRV is associated with adverse outcomes in diabetes.  For example, people with diabetes and low HRV are at increased risk of coronary heart disease.  Moreover, low HRV is an early marker of cardiac autonomic neuropathy, which can lead to heart disease, the number one cause of mortality in people with diabetes.

 

Sounds depressing, right?

 

 

Enter the Heart-Boosting Power of Slow Breathing

When we breathe slowly at around 6 breaths per minute, we synchronize signals coming from our cardiovascular, respiratory, and autonomic nervous systems. 

When we breathe slowly at around 6 breaths per minute, we synchronize signals coming from our cardiovascular, respiratory, and autonomic nervous systems. 

 

To get a little more technical, we have baroreceptors monitoring blood pressure. They sense the changes in heart rate that accompany each breath.  Then, they send their own signals to the heart. 

 

For example, as blood pressure rises, they tell the heart to slow down.  And as blood pressure falls, they tell the heart to speed up.

 

Here’s the issue: there’s about a 5-second lag for signals.  Thus, they end up getting mingled together with the signals from the breath.  One may be trying to increase heart rate while the other is trying to slow it down.

 

But when we breathe at about 6 breaths per minute, we synchronize these messages.  (To breathe at 6 breaths per minute, we need about a 5-second inhale and 5-second exhale (or 4/6 also works). This matches the time lag from the baroreceptors.)

 

When the signals get synchronized, great things happen.  Each breath amplifies heart rate oscillations, leading to greater HRV.  This also balances the nervous system, making us calm and relaxed.  If we do this regularly, it can significantly improve our quality of life.

 

Let’s break these down into a little more detail and look at 4 positive outcomes we get from slow breathing.

 

 

The 4 Key Benefits of Heart-Breath Synchronization for Diabetes

 

1. Improved Heart Rate Variability

 

This is the most potent effect.  As mentioned, when we breathe slowly, we amplify the heart rate oscillations occurring with each breath.  This increases HRV, a critical problem in diabetes.

 

One study published in Nature found that just 2 minutes of slow breathing at 6 breaths/min could bring the HRV of type-1 diabetics to levels of non-diabetic controls.  (Side note: this was the paper that convinced me to start sharing this information.  Nature is one of the most prestigious journals in the world.  If they’re talking about slow breathing and diabetes, I realized my results weren’t so crazy after all.)

 

A long-term study of people with type 2 diabetes and ischemic heart disease found that one year of slow diaphragmatic breathing significantly increased HRV, and this wasn’t even at precisely 6 breaths per minute. Just slowing down the breath was enough to boost HRV.

 

And better HRV means better cardiovascular health and a longer life.

 

It also means more resiliency to diabetic stressors, but I’ll save that for another blog post.

And better HRV means better cardiovascular health and a longer life.

 

2. Efficiency and Blood Flow

 

When bodily messages come into harmony, it creates efficiency.  Efficiency means your body doesn’t have to work as hard to complete its normal processes.

 

This efficiency also improves blood flow, a fundamental problem in diabetes.  For example, the same 2-minute study mentioned above found that slow breathing also improved arterial function.  Better arteries, more blood flow, and less chance of complications.

 

 

3. Reduced Blood Pressure

 

Slow breathing has consistently been shown to lower blood pressure.  A 2019 meta-analysis found an average systolic blood pressure reduction of about 5 points from slow breathing for about 20 minutes daily.

 

The blood pressure-reducing effects of slow breathing have also been shown in diabetes.  In a study of 65 type-2 diabetics with hypertension, slow breathing significantly reduced systolic and diastolic blood pressure.

 

These results are significant because Johns Hopkins Medical Center reports that people with diabetes are twice as likely to develop hypertension.  It’s also estimated that anywhere from 40 to 80% of diabetics have hypertension.  Moreover, a person with diabetes and hypertension is four times more likely to develop heart disease.  For these reasons, preventing and treating hypertension is a chief concern in people with diabetes.

 

Slow breathing provides one complementary therapy for doing just that.

 

 

4. Less Stress & Anxiety

 

And lastly, we can’t discuss heart problems without discussing stress.  We know when we’re stressed, we have chronic activation of the sympathetic (fight-or-flight) nervous system.  This raises heart rate and blood pressure, adding extra strain on our hearts.

 

Fortunately, slow breathing is one of the fastest and most effective ways to alleviate stress. You’ve probably been told at some point in your life to “just take a deep breath.”  It turns out there’s some solid science for this statement.

 

Slowing down the breath, especially with a longer exhalation, increases activity in the parasympathetic nervous system (rest-and-digest), reducing stress and increasing relaxation. Slow breathing also reduces activity in the amygdala (often referred to as the “fear center”), which also helps reduce stress.

 

 

Slow Breathing is a Superpower for Your Heart

 

To recap, slow breathing at about 6 breaths per minute is excellent for our hearts, especially if you have diabetes.

 

It harmonizes messages being sent from the cardiovascular and autonomic nervous systems.  This leads to a ton of benefits, but here are 4 critical ones for diabetic heart health:

 

  • Improved heart rate variability

  • Increased efficiency and blood flow

  • Lower blood pressure

  • Less stress and anxiety

 

For these reasons, the paper published in Nature concluded:

Slow breathing could be a simple beneficial intervention in diabetes.
— Nature Scientific Reports

 

Simple and beneficial, indeed.

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

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.

- 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

 

4. “Recitation of the rosary, and also of yoga mantras, slowed respiration to almost exactly 6/min, and enhanced heart rate variability”

- Bernardi et al. 2001*

 

5. “when you inhale, your heart rate (the number of times your heart beats per minute) naturally rises; when you exhale, it slows down again. This is true for everyone.”

- Leah Lagos

 

6. “Exhales slow the heart rate; the longer we spend on the outbreath, the more the nervous systems relaxes.”

- Emma Seppälä

 

7. “Your respiratory and cardiovascular systems are designed to work in synchrony. […] Your breathing acts as a stimulus for the heart. In physics, this kind of relationship between your breathing and your heart rate is called resonance, a property of a system where two oscillating components interplay with each other, producing increases in oscillation amplitude.”

- Inna Khazan

 

8. “These waves seem to oscillate around 0.1 Hertz. When we inhale and exhale at that rate, our respiration has the potential to optimize the rhythm of various mechanisms and align them with our heart rate. ‘When you breathe at that same rate, it’s like pushing the swing at the perfect moment,’ Noble says.”

- Timothy Meinch

 

9. “If you found that your heart beats faster when you breathe in than when you breathe out, you are correct.  You have discovered that every breath you take affects your heart rate.”

- Michael J. Stephenson

 

11. “The heart itself rests on the dome of the diaphragm […] Each time the diaphragm moves, it tugs on the heart.  Imagine a game of balloon toss, with the heart gently bounced on this elastic trampoline, rocked with each breath, approximately 20,000 times a day.”

- Robin Rothenberg

 

12. “Thank you from the bottom of my heart, which is, of course, my diaphragm.”

- Jill Miller

 

13. “Slowing the breath down activates the prefrontal cortex and increases heart rate variability, which helps shift the brain and body from a state of stress to self-control mode. A few minutes of this technique will make you feel calm, in control, and capable of handling cravings or challenges.”

- Kelly McGonigal

 

14. “There is one way of breathing that is shameful and constricted. Then there’s another way; a breath of love that takes you all the way to infinity.”

- Rumi

2. A Unexpected Truth: Use Your Heart to be More Objective

I feel like I process information more objectively. If there's a bad call, or a player does something unexpected on the court, I can inhibit my reaction and quickly determine what needs to happen next with less effort.

- Client of Leah Lagos, excerpt from Heart Breath Mind

This was the result of heart rate variability (HRV) training via slow breathing. As counterintuitive as it might sound, current science tells us that the more we train our hearts, the more objective we become.

It’s actually our pesky (albeit valuable, lol) brains that trick us into excess emotional reactivity, anxiety, stress, rumination, and on & on.

So to be more rational, use your heart, not your head : )

3. Why You Should Practice Abdominal Nose Breathing

However, when we breathe through the nostrils and into the abdomen, not only do we breathe less frequently, but our exhalations are prolonged. What this means is that abdominal nose breathing not only makes more oxygen available to our bodies in a more efficient manner, but it also stimulates the sympathetic nervous system less frequently.

- The Tibetan Yoga of Breath

That is all : )

4. The Best Part about Breathing

The best part about breathing is that we can satisfy our craving to read and learn while also applying that wisdom in our lives. There’s no abstraction. It’s as easy as “sit down and breathe like this for a few minutes and see how you feel.

Sure, I write to try to make it fun and philosophical. But when it comes down to it, you just sit there and breathe. No one can take it away from you, and you don’t need any special training. You just do it.

1. Demonstrations of Breathing & Love

Demonstrations of love are small, compared with the great thing that is hidden behind them.

- Khalil Gibran

Call it what you’d like, prana, qi, & so on, but the same is true: Demonstrations of breathing are small compared with the great thing that is hidden behind them.

Based on about 4 years of research and self-practice, the 4 key ways that regular breathing practices help diabetes are by:

3. Breathing for (non) Diabetics: “Raising Our Heads Above the Clouds

But many of the same interventions that can help us get our heads above water can just as effectively be devoted to raising our heads above the clouds.

- Steven Kotler and Jamie Wheal, Stealing Fire

This is unquestionably true for breathing. Although everything I read, practice, and share is focused on keeping my “head above the water” as a diabetic, they can also “raise your head above the clouds” if you’re not diabetic.

Interesting side note: it’s typically broken people that find supplemental modalities like breathing—I guess because we need them the most : ) But if you’re not broken, all the benefits of breathing will be even more helpful.

So here’s to using our breathing to stay afloat, or rise above the clouds, today.

Applying Gandhi's Wisdom, The Science of Learning, and $100 to Your Breath

Hey,

Welcome back to another issue of the The Breathing 411. Here are 4 thoughts, 1 quote, and 1 answer that I hope you enjoy this week!

1. Why Your Breathing Gains Get More Boring With Time

Gaining the first $100 at the track feels much better than winning the second $100, which feels better than winning the third $100, and so on. Eventually, if things get good enough, there is almost no psychological benefit when they get even better. This relationship reflects what economists call diminishing marginal utility.

- Barry Schwartz, The Paradox of Choice

Building off last week’sSatisfaction Treadmill,” let’s not forget this passage when our breathing, or anything else we’re working on, starts feeling boring.

We’re still making gains. They just might not feel as dramatic, because we already feel so good.

2. Applying Gandhi’s Wisdom and Scientific Research to Appreciate Your Favorite Breathing Practice

Humans do not give greater credence to an objective record of a past event than to their subjective remembering of it.

- Make It Stick: The Science of Successful Learning

Translation: What you experience holds more weight than what you learn.

As the Make it Stick authors also tell us, research shows it’s “nearly impossible to avoid basing one's judgments on subjective experience.

Some might say this is a flaw of being human—we base things on emotions instead of facts. I say it’s amazing, at least when it comes to breathing : )

Because with breathing, this means that whatever you experience is what’s true for you. Your practice is yours; no science or statistics needed.

Practically, it means that if your experience with Wim Hof was terrific, then you should keep doing it. Or, if slow breathing was life-changing, do that.

As Gandhi tells us, “As long as you derive inner help and comfort from anything, keep it.” This applies perfectly to breathing. And science agrees.

3. Mouth Tape: End Mouth Breathing for Better Sleep and a Healthier Mouth

Becoming a nose breather is a process, but even repeated cycles of just a few minutes of nose breathing can effectively train your body to do it regularly.

- Dr. Mark Burhenne, Mouth Tape: End Mouth Breathing for Better Sleep and a Healthier Mouth

Mouth taping is odd. It’s perhaps the most important thing we can do for our health, but it’s hard to recommend without sounding slightly crazy.

Fortunately, Dr. Mark Burhenne wrote this great article, which covers basically every aspect of taping up at night. It will now be my go-to for anyone interested in the topic.

Enjoy the great read, and enjoy sharing it with others.

4. To Take Care of Your Heart, Take Care of Your Breath

In other words, the primary role of the heart is to distribute the oxygen brought into the lungs during inhalation, and to bring carbon dioxide back to the lungs where the excess can be breathed out.

– Patrick McKeown, The Breathing Cure (pg. 237)

I’ve never thought of it this way: Your heart’s main job is to make your breathing useful to the rest of your body. So from this viewpoint, it’s obvious they must work together. And all the science we review makes perfect sense.

Of course breathing efficiently would make our hearts work more effectively. And of course we would see measurements like heart rate variability increase and blood pressure decrease.

That’s because the heart and breath can’t be separated. Thus, we might even say, to take better care of your heart, take better care of your breath.

Deep breathing is a potent inducer of the parasympathetic system. The release of acetylcholine not only calms our organs, it also stimulates the release of serotonin, dopamine, and prolactin, the feel-good hormones targeted by medicines like Prozac and Zoloft. But yoga and breathing exercises produce this effect naturally and without side effects.
