4 Thoughts



1. The Famous 10-18% Nasal Breathing and Oxygenation Study

“We here show that arterial oxygenation is improved in healthy awake subjects during nasal breathing as compared with mouth breathing.”

- 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.

4 Thoughts


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’s “Satisfaction 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.”

Oxidative Stress and Civilized vs. Wild Breathing

4 THOUGHTS

1. Is There Really “Dysfunctional” Breathing?

"Breathing is one of the body’s critical functions.  When its fundamental processes break down, the body will compensate, calling on structures such as the core muscles to help maintain respiration."

– Patrick McKeown, The Breathing Cure (pg. 152)

Breathing is the body’s most critical function. So as Patrick tells us, even if we do it incorrectly, the body will compensate by activating whatever muscles are needed to keep it going. Breathing takes precedence over everything.

So, we might say that breathing will always remain "functional" in that it will always do its main task of keeping us alive. But, it might be severely inefficient.

Thus, "dysfunctional" breathing is really just inefficient breathing.

This gives us two options. We can develop optimal breathing, which uses the nose and activates the diaphragm. Or, we can ignore our breathing and let the body compensate on its own, usually in ways that are detrimental to our health.

I say we choose option 1.

2. Diabetes, Oxidative Stress, and Slow Breathing

High blood sugars generate free radicals. These excess free radicals deplete antioxidants and ultimately cause oxidative stress. This negative feedback loop has been described as the "single unifying mechanism for diabetic complications."

To combat this, people with diabetes would ideally find a way to both reduce free radical production and increase antioxidant defenses. Slow breathing provides a natural and effective method of doing just this.

For example, slow diaphragmatic breathing reduces post-meal oxidative stress. It also reduces oxidative stress associated with intense, long-duration exercise. The hallmark paper on slow breathing & diabetes published in Nature even said:

"…our results lead to the hypothesis that slow breathing may exert some antioxidant effect, possibly via parasympathetic stimulation."

Taken together, slow breathing appears to be a simple and effective way to help with oxidative stress in diabetes. Quite amazing.

3. Apparently Slow Breathing Makes Food Taste Better

"Smooth, relatively slow breathing maximises delivery of the particles to the nose. Food smells and tastes better if you take your time."

- Vice, Apparently Slow Breathing
Makes Food Taste Better

This was a fun read from Vice. At first, I thought it seemed a bit silly. But the study was originally published in PNAS, so maybe there’s something to it?

If we pair this advice with Ch. 7 of Breath, we might say that to enjoy a meal, breathe slowly and chew more. I’m constantly working on the chew more part…

Enjoy!

4. Take the Nose, Take the Life

"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."

- Michael J. Stephen, MD, Breath Taking

This is on the first page of the book. Although Dr. Stephen never mentions the power of the nose again, it’s a rather remarkable statement that emphasizes just how important the breath (and nose) were to ancient cultures.

Investing, Sleep, and the Most Important Rest in a Day

 

Greetings,

Here are four thoughts, one quote, and one answer (like "Jeopardy!") to consider this week. Enjoy!

 
 
 
 

4 THOUGHTS

As I have been making my way through Patrick McKeown’s latest book, The Breathing Cure, I’ve been reminded of just how powerful all this breathing stuff is. Patrick has sections on breathing for diabetes, epilepsy, hypertension, and more.

Of course, despite the catchy title, breathing does not "cure" any of these ailments. Still, it’s quite remarkable to see all the conditions it can help with.

Upon reflection, this makes a lot of sense if we remember that breathing is like an index fund for health. It invests a small amount into a wide range of the body’s functions, such as lung and heart health, autonomic balance, and sleep.

Over time, these tiny improvements combine and compound into overall better health. And as Patrick’s new book shows, these benefits can be helpful in many different conditions.

The key, however, is to find a breathing practice that is right for you, get started, and be consistent. Here’s to safely investing in your health today.

P.S. Unlike most financial investments, however, you also get an immediate return on investment with breathing. For example, just two minutes of slow breathing can improve autonomic balance and enhance decision-making.

2. Mouth Tape is Passive Income for Your Health

Wealthy people grow their wealth in their sleep.

Healthy people grow their health in their sleep.

Taping your mouth at night is like passive income for your health. It requires only a small upfront investment: putting the tape on before you go to sleep. All of the benefits—like deeper sleep, improved mental clarity, and reductions in sleep apnea—come without any additional effort.

Thus, we might be wise to take the advice of a 1983 paper published in the journal Sleep: "While asleep, shut your mouth and save your brain."

3. Slower Breathing Facilities Eudaimonia via Your Vagus Nerve

"This accumulating body of evidence suggests that slow-paced breathing is a cost-free and readily available way to facilitate eudaimonia by lowering blood pressure, improving psychophysiological well-being, and increasing happiness."

- Christopher Bergland—Slower Breathing Facilitates Eudaimonia…

As you will learn in this article, Eudaimonia is "the condition of human flourishing or living well." So, when a headline implies that slow breathing might help us achieve this, I’m all in. This quick read lived up to its promise. Enjoy!

4. Breathing Tranquility

"Tranquility. It’s the feeling we have when we truly TRUST ourselves. When we know we’re headed in the right direction and we’re able to quit comparing ourselves to everyone else and stop second guessing ourselves every 5 seconds."

- Brian Johnson

Although slow breathing induces a sense of tranquility, that’s not what this made me think of. It made me think of the tranquility that can come when you find the right breathing practice for you.

We’re all different, and there’s no "perfect" method for everyone. Tranquility comes when you find the one that’s right for you and you know you’re headed in the right direction, whether it’s the latest popular technique or not.

My breathing tranquility? Seven seconds in, eleven seconds out. Repeat.
