The Breathing 4.1.1.

 

I am trying a new format this week. I’m calling it “The Breathing 4.1.1.”

Below, I share 4 thoughts, 1 quote, and 1 answer (think “Jeopardy”). Enjoy!

 
 
 
 

4 THOUGHTS

1. Expert Q&A on Sleep Tape

James Nestor’s first "expert Q&A" episode has been released. It’s on sleep tape with Dr. Mark Burhenne. I especially appreciated Dr. Burhenne’s confidence in recommending that people wear mouth tape. Watch Interview Here.

2. An Easy Hack for Dropping SpO2 during Breath Holds

I’m always playing around with my breath holds. Lately, I’ve been performing a full exhale before each hold.

Normal Breath In —> Fast and Complete Exhale Out —> Hold

I’ve seen additional SpO2 drops of 5-10% (!). My breath holds are not as long, but I’m getting into intermittent hypoxia easier. I really try to empty my lungs as much as possible to get more significant drops in SpO2.

3. Is Tissue Hypoxia Really the Problem?

“In this, chronic overbreathing will not create ‘hypoxia’ in tissues; this is a fact that many Buteyko adherents consistently get wrong.  The real damage from overbreathing comes from the constant energy the body has to expend to run more cells anaerobically and to constantly buffer for carbon dioxide deficiencies.” - James Nestor, Breath

I talk about tissue hypoxia a lot. Here, James says that it’s not necessarily tissue hypoxia that’s the problem, but the body’s response to prevent it from happening that causes the damage. In any case, the underlying issue is the same: We need to get an adequate supply of oxygen for our cells to function correctly.

4. A Simple Way the Breathe Light

Teaching people to breathe "light" is often tricky. However, in Restoring Prana, Robin Rothenberg provides one of the most practical ways I’ve heard: Imagine taking up less space with each breath. I imagine less air being pulled into my nose with each inhale, and each exhale disturbing less air around me. Give it a shot.

Nasal Nitric Oxide is My New Favorite Gas

The nose warms and humidifies incoming air. We’ve heard that a lot.

However, when you dig into the scientific literature, you learn that nitric oxide (NO) might outweigh all other aspects of nasal breathing. It’s actually hard to overstate the benefits of nasal NO.

Which brings us to this week’s paper:

Nasal Nitric Oxide in Man

- Published in Thorax in 1999 (Read Full Summary Here)

This was a great overview of the many functions of nasal NO. Here are a few of my favorites. Check out the full summary for more.

The general consensus is that NO is continuously released in the paranasal sinuses. Because of this continuous release, a lower flow rate will result in higher concentrations. This could be yet another benefit of slow breathing: Increased nitric oxide delivery to the lungs.

Another amazing benefit of nasal NO is that it increases arterial oxygenation. For example, one study showed that nasal breathing increased tissue oxygenation 10% more than mouth breathing.

Finally, and this was my favorite part, a study showed that breathing humidified air through the mouth did not increase oxygenation; however, breathing supplemental NO through the mouth increased oxygenation similar to what is seen in nose breathing.

Although the warming and moistening effects are important, this suggests that nitric oxide might explain many of the benefits of nasal breathing.

I am continually amazed by everything nitric oxide does in the body.  I think it’s my new favorite gas (never thought I’d have one of those!).

In good breath,
Nick
