4 Thoughts


1. The Breath Should Enter Very Subtly

“‘Very subtly’ means that when the nose draws in the outside air, it should draw it very subtly so that the ear should not hear it.  Being subtle and fine is the gate to life. … The inhalation should, therefore, be done in a subtle and fine way.”

- The Primordial Breath, Volume I

This is always my #1 tip for breathing: make it quiet and subtle. Remember, “Being subtle and fine is the gate to life…”

2. Effort Leads to Effortless

“It takes a lot of effort for our fitness to appear natural and effortless. But just because it appears effortless does not mean that no effort was made.”

- Haemin Sunim, The Things You Can See Only When You Slow Down

The same is true for breathing. To breathe in a “subtle and fine way” takes deliberate practice and effort. I’m still working on it. I hope you are too : )

3. Maybe Loud Breathing is OK in Modern Yoga Classes?

I’m clearly a big fan of quiet breathing : ) Traditional yoga practices are too.

However, if you go to a modern group yoga class, you’ll hear a lot of loud breathing. Physiologically, I’ve always thought it was wrong…

But maybe there’s more to that loud breathing than just physiology?

In The Joy of Movement, Kelly McGonigal tells us that loud breathing during yoga is a critical component of social bonding and group flow:

“Studies show that yoga, like dancing, can create social bonds. … The breath becomes the beat that drives the flow of poses, and the sound of the group inhaling and exhaling in unison provides a satisfying sensory feedback.”

Of course, you’re not going to hear me breathing loudly in class now (I’m an introvert, anyways 😂). But let’s not overlook the social and emotional bonding that it might bring. Perhaps they are most critical in today’s world.

***

P.S. Maybe we even naturally began loud breathing during group yoga classes out of a deep yearning for more social connection? Just a thought…

4. Smiling and Breathing, Part II

“Stop. Take three deep breaths and smile everywhere in your body, observing what’s happening in your body. Proceed now with kindness and understanding.”

- Deepak Chopra

To complement last week’s thought on smiling, I was searching for info on the Buddha’s half-smile, when I stumbled across this quote.

At first, it might seem cliché. But, like most great teachers, Deepak simply distilled the science of smiling and breathing into a practical exercise.

Remember what we learned last week:

The act of smiling makes you happier.

Slow deep breathing makes you happier.

So set your breathing timer, put a slight smile on your face (Buddha-style), and “proceed with kindness and understanding.”

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 : )

Exciting News: A New Breathing Gas Discovered

 

Happy Monday. There was a breakthrough in breathing research over the past few weeks: A new breathing gas has been discovered. I hope the extra hour of sleep you got this weekend will help this exciting news sink in even deeper.

OK, let’s get to it. Here are 4 thoughts, 1 quote, and 1 answer for you to think about as we begin November.

 
 
 
 

4 THOUGHTS

1. A New Breathing Gas Discovered

"Thus, H2S [hydrogen sulfide] produced by CBS surely has a crucial role in maintaining eupneic-pattern respiration."

- Nature, Communications Biology

Hydrogen sulfide. It’s toxic, and it’s what gives rotten eggs their rotten smell. It also helps maintain our breathing.

A study published in Nature: Communications Biology on October 16, 2020, found that a small amount of hydrogen sulfide is critical to maintaining normal breathing. It does this through modification of the neural connections in the region of the brain that controls breathing.

When hydrogen sulfide production was stopped in rats, normal breathing turned to gasping, implying that it is vital to maintaining rhythmic breathing.

From a practical perspective, I’m not sure what this means yet. At a minimum, breathing now appears to be a four-gas system: oxygen, carbon dioxide, nitric oxide, and hydrogen sulfide.

We’ve found ways to breathe to optimize the first three. However, it’s not yet clear if the way we breathe (or do anything else, for that matter) can influence hydrogen sulfide.

In any case, as a fellow breathing nerd, I hope you find this as fascinating and humbling as I did. Here’s to the joy of never-ending learning.

P.S. Here’s a short summary of these findings from ScienceDaily.

2. The Single Most Important Part of the Breath

"Interestingly, Törnberg et al. recently showed that more NO is released from the nasal passages during nasal inhalation compared with exhalation." - Lundberg et al. (2008)

Here is yet another reason why inhaling through your nose might be the single most important part of breathing: nitric oxide (NO) production is much greater during inhalation than exhalation.

Here’s the finding from the paper mentioned above: "There was a marked flow dependency of nasal NO output, with the highest levels observed during inhalation at flows similar to those seen during normal breathing." - Törnberg et al. (2002)

In hindsight, this makes complete sense. NO helps protect our lungs from inhaled pathogens and it redistributes blood flow in the lungs. So, of course our bodies would maximize it on the inhale. But it wasn’t until I read these two papers that it made sense to me.

"The obvious is that which is never seen until someone expresses it simply.” - Kahlil Gibran

3. What Focusing on the Breath Does to Your Brain

"Conversely, it may be possible to reduce fear and anxiety by slowing down our breath." - Greater Good, UC Berkeley

Here is a quick-reading article, packed full of excellent information, from The Greater Good Science Center at UC Berkeley. Anytime you see a headline like "Managing stress: Is it all in the breath?" you know it’s going to be a good read. Enjoy!

4. Sleep Scientists Call for the Elimination of Daylight Saving Time

"It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time."

- Journal of Clinical Sleep Medicine

I hope you all enjoyed the extra hour of sleep you got this weekend. The world’s leading sleep scientists say your body will function better, and they suggest we keep it this way (Standard Time) forever.

The above article is pretty short. But if you’re interested, here’s an even more concise summary, along with a rather impressive list of organizations that support the permanent change to Standard Time.

Because nasal breathing at night changed my life, I am endlessly fascinated with sleep. So I hope we all enjoy the next few months of better sleep and better optimization of our body's wake-light cycles.

The Simplest Way to Increase Nitric Oxide Through Nasal Breathing

 

Hello, and happy Monday. Here are 4 thoughts, 1 quote, and 1 answer (like "Jeopardy") related to breathing that I hope you enjoy.

 
 
 
 

4 THOUGHTS

1. Can Mouth Breathing Increase Nitric Oxide?

Yes, but only if done on the exhale.

Nitric oxide (NO) is continuously produced in the nasal cavity. When we inhale through the nose, we harness this wondrous molecule and its benefits in the airways and lungs.

But if we also exhale through our nose, some of it gets washed out. Conversely, if we exhale through our mouth, the NO continues to accumulate in the nasal cavity. Then, more is brought in with the next nasal inhale.

In through the nose, out through the mouth.

Here’s what a researcher at the UCLA School of Medicine says:

"Exhaling through the nose is highly wasteful in that the NO would be expelled away from the lungs, where it is needed most." - Louis J. Ignarro, Inhaled NO and COVID-19

While I personally don’t recommend exhaling through the mouth all the time, there are clearly times when it might be beneficial, even if only for short periods.

The next thought has a few ideas about putting this knowledge into practice.

2. Increase Oxygenation by 10% (without increasing carbon dioxide)

"The subject inhaled through the nose with the mouth closed and exhaled through the mouth with the nose blocked. Thereby, a maximum of NO from the nasal airways is inhaled while a minimum is lost during exhalation." - Lundberg et al. (1996)

This protocol, nose in - mouth out, led to a 10% increase in tissue oxygenation when compared with mouth in-nasal out.

Notably, there were no significant carbon dioxide changes between protocols. Thus, by inhaling through the nose and exhaling through the mouth, we can increase tissue oxygenation without increasing carbon dioxide.

It’s all due to nitric oxide.

We should not base all our breathing on any one conclusion. And many factors need to be weighed, such as moisture and heat loss from exhaling through the mouth. But these results are intriguing nonetheless.

Here’s a simple way I put them into practice: I start each slow breathing session with 3-5 nose in - mouth out breaths before switching to nose in - nose out.

This study also implies that nose in - mouth out could increase oxygenation to the working muscles during exercise. So, if you’re uncomfortable with nasal-only breathing during your workout, switching to nose in - mouth out could be a beneficial compromise from an oxygenation perspective.

3. Why Slowing Your Breathing Helps You Relax

"By repeatedly stimulating the vagus nerve during those long exhalations, slow breathing may shift the nervous system towards that more restful state, resulting in positive changes like a lower heart rate and lower blood pressure." (my emphasis)

- BBC, Why Slowing Your Breathing Helps You Relax

It’s always fun to find an article reporting the science behind slow breathing from a news outlet like BBC. They even present some information you might not have considered, like how taking "big breaths" might benefit relaxation.

The article also touches on everything from pain to arthritis and provides many useful references. It's an excellent summary. Enjoy!

Thanks to 411 reader A. P. for inspiring this thought.

4. What is Breathing? And is it Woo-Woo (part II)?

When I was drafting last week’s thought about breathing being woo-woo, my grammar editor said that I was using the word "breathe" too much. Almost ironically, the synonym it suggested was: live.

I thought, "funny that a word synonymous with life itself is often considered woo-woo." But at the same time, interchanging "breath" with "life" is borderline woo-woo : )

But this is an appropriate synonym. Because at its root, what is breathing? At the risk of sounding a bit woo-woo myself, here is one answer: breathing is living.
