The Breathing 411 - What do 5,649 and 28,800 Have in Common?

 

Hello and Happy Monday. Welcome to another edition of The Breathing 4.1.1.

Below you’ll find 4 thoughts, 1 quote, and 1 answer (think "Jeopardy"). Enjoy!

 
 

 
 

4 THOUGHTS

1. What do 5,649 and 28,800 Have in Common?

"The average daily step count required to induce feelings of anxiety and depression and decrease satisfaction with life is 5,649. The typical American takes 4,774 steps per day. Across the globe, the average is 4,961." - Kelly McGonigal, The Joy of Movement

Active people become anxious and lose life satisfaction when their step count drops to 5,649 or less. That’s a bit staggering, given the U.S. and global step count statistics Kelly cites.

That passage got me thinking, "I wonder if there is a similar idea for breaths per day?" However, with breathing, it would be opposite: The more breaths you take, the more unhealthy you are. Sure enough, there is something close:

"Recent evidence suggests that an adult with a respiratory rate of over 20 breaths/minute is probably unwell, and an adult with a respiratory rate of over 24 breaths/minute is likely to be critically ill.” - Respiratory Rate: The Neglected Vital Sign

If your spontaneous breathing rate is over 20 breaths per minute, you are "probably unwell." That comes out to about 28,800 breaths per day.

So, do you want to feel unwell and anxious?
Take less than 5,649 steps and breathe more than 28,800 breaths per day.

Want to be happy and healthy?
Walk more, breathe less.

P.S. That 28,800 number might even be too high. James Nestor shares some great ancient wisdom on this:

"Chinese doctors two thousand years ago advised 13,500 breaths per day, which works out to nine and a half breaths per minute. "

2. The Most Fundamental of the Fundamentals

Last week, Kobe Bryant provided an excellent example of the importance of practicing the fundamentals. We talked about how we don’t need to worry about the "latest and greatest" breathing technique. Instead, we need to focus on the fundamentals. They’re simple, but they’re not easy.

We can take that thought step farther: Breathing itself is the most fundamental of the fundamentals. We’re all in the sport of life. And that requires breathing…at least 13,500 times a day : ) So, let’s optimize that first, then work on the fundamentals of your particular sport or profession.

3. Bring Attention & Intention to Your Breathing

"Attention without intention is wasted energy." - Chris Bailey, Hyperfocus

This quote makes complete sense in terms of productivity, self-improvement, and group workouts (CrossFit, yoga, etc.). But the minute you apply it to something like sitting down to breathe, it can get misinterpreted:

"Set an intention for your breathing practice."

"Be intentional with your breathing today."

It’s just begging to be put in the "woo-woo" category and not be taken seriously.

But intentions are powerful (hence the quote from Chris Bailey). So a compromise I have made is to set scientific intentions before each slow breathing practice. "I am going to increase my heart rate variability" or "I am going to balance my autonomic nervous system."

These are just facts that I state at the beginning of my practice that work as intentions, without feeling woo-woo.

I find it to be an excellent way to give the practice more meaning. (And don’t forget to celebrate afterward!)

4. Slow Breathing for Hypertension

Slow, controlled breathing (<10 breaths per minute) has consistently been shown to be beneficial for reducing blood pressure. So much so that it is recognized by the American Heart Association for its positive effects. (They’ve given it a Class IIa, Level of Evidence B. Here’s what that means.)

This got me thinking about a paper published back in 2005 that I loved. They concluded:

"Slow breathing showed the potential to be a simple and inexpensive method to improve autonomic balance and respiratory control and reduce blood pressure in hypertensive patients." - Joseph et al. (2005)

The interesting part was that the authors provided an exciting hypothesis for how that’s occurring using autonomic function as the foundation. That hypothesis inspired me to create this little graphic to help get the point across.

The Breathing 411 - The lung microbiome, David Blaine, and a perfect breath

 

Happy Monday! Welcome to another edition of The Breathing 4.1.1.

Below you’ll find 4 thoughts, 1 quote, and 1 answer (think "Jeopardy").

Thank you for reading!

 
 

 
 

4 THOUGHTS

1. On Practicing the Fundamentals

"If someone at Kobe’s level needs to commit hours to practicing the fundamentals, then so do all of us. Kobe taught me a pivotal lesson that morning. The basics are simple, but not easy."
- Alan Stein Jr., Raise Your Game

Imagine the best basketball player on the planet allows you to watch him practice. Then, he spends hours working on his fundamentals. Nothing fancy, no showboating, just the basics. That’s exactly what Alan Stein saw when he watched Kobe Bryant practice during his prime.

We talk about breathing here, not the highest level of basketball ever played. But the message is the same.

With all the fancy breathing techniques and new approaches, it’s easy to be looking for the "next thing" (—> guilty here <— ). But let’s not forget that it all comes down to the basics. They’re simple, but they’re not easy.

(This idea, like many, was inspired by knowledge from the Optimize Program.)

2. Oxygen Therapy Harms the Lung Microbiome

We’ve discussed how inhaled oxygen can lead to adverse effects in people with diabetes. Specifically, high levels of inhaled oxygen can reduce arterial function. But there might be other problems with oxygen therapy, especially when done over prolonged periods.

For example, your lungs have their own microbiome (pretty neat). And a recent study showed that inhaled oxygen harms this microbiome, leading to an increased risk of lung damage. This idea is especially relevant during COVID-19:

“Upon hospitalization, these patients are administered oxygen in an attempt to bring their levels back up to normal. However, a new study hints that this universal therapy may have unintended consequences via an unexpected source -- the microbiome.”

3. David Blaine on Breath Holds, CO2, and 45 Minutes Without Air

David Blaine was recently on the Joe Rogan Podcast. They began talking about breath-holds within 5 minutes (this link should take you right to it).

Here are two quotes I loved from it:

"The breath-holding thing is all about like, a CO2 build up in the bloodstream, and it’s about a tolerance level to it…"

And when Joe asks about the panicked feeling you get when holding your breath, David’s reply is:

That’s not an O2 deprivation. That’s a trigger from a CO2 build-up, which is giving you an alert…"

All of you "breathing nerds" already knew this. But it is little tidbits like these that help the general population learn.

He goes on to talk a little about pre-breath-hold hyperventilation, blacking out, and how we can go 45 minutes without air.

In addition to the breath-hold stuff, it’s a fascinating interview.

4. Is there a Perfect Breath?

“What is the perfect breath? Far from being some noble yet unreachable goal that takes years of rigorous practice to master, a perfect breath is any breath you take for which you are completely and mindfully aware.” - Al Lee & Don Campbell

That definition is, well, perfect. But let’s not forget about James Nestor’s perfect breath, which has deeper roots in science and physiology:

"They discovered that the optimum amount of air we should take in at rest per minute is 5.5 liters. The optimum breathing rate is about 5.5 breaths per minute. That’s 5.5-second inhales and 5.5-second exhales. This is the perfect breath."

The Breathing 4.1.1. - The Best Breathing Class You Haven’t Heard Of

 

Hello, and Happy Monday! Welcome to another edition of The Breathing 4.1.1.

Thank you for reading this. Putting together the 411 emails each week is one of my favorite things to do, so I appreciate that you’re here reading it.

Now, on to the email. Below you’ll find 4 thoughts, 1 quote, and 1 answer (think "Jeopardy"). Enjoy!

 
 

 
 

4 THOUGHTS

1. Breath Practice versus Breath Training

Breath Practice: Time you spend every day performing breathing exercises that are comfortable and beneficial to you. Think of it as self-care. For me, this would include my 15 minutes of slow breathing first thing in the morning.

Breath Training: Time you spend deliberately pushing yourself to improve your breathing. For example, if you can comfortably box breathe with a 4-4-4-4 rate, you might spend some time at 5-5-5-5 rate as training.

Breath Training is always Breath Practice, but Breath Practice is not always Breath Training.

(This thought was inspired by pages 51-53 of Breathe to Perform.)

2. The Best Way to Make Your Breathing Practice Stick: Celebrate!

"Celebration will one day be ranked alongside mindfulness and gratitude as daily practices that contribute most to our overall happiness and well-being." BJ Fogg, Tiny Habits

Are you trying to make your breathing practice a habit? BJ Fogg, creator of the Behavior Design Lab at Stanford University, says that if he taught you his "Tiny Habits" approach, the first thing he would do is help you celebrate better.

If you spend 1 minute focused on your breath, celebrate it. If you already have a solid practice, try adding some celebration to the end.

I started doing this and love it. After my slow breathing session, I reward myself with a small celebration. After my breath holds, the same thing.

Is it cheesy? Kind of. Is it rooted in science from the leader in habit development at Stanford? Yes. Will anyone know? Nope. Give it a shot.

(See the P.S. below for a great example of celebrating the small stuff.)

3. The Best Breathing Class You Probably Haven’t Heard Of

That celebration idea came from Brian Johnson’s Optimize program (I adapted it for breathing, but it can be used in any aspect of life). If you’ve been following my work for a while, you probably know that Brian Johnson is one of my favorite teachers on the planet. Actually, he is my absolute favorite.

He has an "Optimal Breathing 101" course that is phenomenal. He combines research from all of the best books on breathing into a succinct and practical course. It’s awesome.

He also recently reviewed Breath: The New Science of A Lost Art. Again, phenomenal.

The Breathing 4.1.1. - Are Type 1 Diabetics Protected from COVID-19?

 

Welcome to the "The Breathing 4.1.1."

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

 
 

 
 

4 THOUGHTS

1. Are Type-1 Diabetics Protected from Serious COVID-19 Complications?

Not exactly breathing related, but a short article recently published in Medical Hypotheses proposed the following: Type-1 diabetics might be "spared" from the more severe complications of COVID-19 because we produce higher quantities of a specific class of pro-inflammatory cytokines called Th-1.

Thus, the reason our insulin-producing beta cells are destroyed might be the same reason we’re protected from COVID-19. Awesome, I guess?

Thanks to Craig Kasper (also a type-1 diabetic) at Bravest for sharing this article with me!

2. Inhale-to-Exhale Ratio: Does it Matter?

Most studies show that either (1) an equal inhale-to-exhale ratio or (2) a longer exhale are both useful for improving cardiovascular and autonomic function. Longer exhalations are associated with more relaxation, whereas equal breaths are more balancing for the nervous system.

But the most critical factor is finding which approach feels most comfortable to you. And this is backed by science.

3. Inverting the Breathing Gears for Down-Regulation

The Skill of Stress course is excellent. I’m working my way through it slowly, but one thing I loved was Emily’s way of inverting the "Breathing Gears" to down-regulate.

Here’s the idea. If you’re stressed and breathing in and out through your mouth, don’t immediately try to switch to nasal in, nasal out. Gear down slowly. For example, you could follow this progression to downshift your nervous system:

  1. Mouth in, Mouth out (Progressive)

  2. Nasal in, Mouth out (Down)

  3. Nasal in, Nasal out (Regulation)

4. Why Wim Hof Doesn’t Care about Nose or Mouth Breathing

"Just breathe mother f*****!" is a famous Wim Hof one-liner. Along with his saying that "any hole will do" when asked how to breathe during his method.

But James Nestor nailed it when Joe Rogan recently asked him why Wim doesn’t care about nose or mouth: "He wants to make this easy and accessible for people…so many people can’t breathe through their noses…"

Wim’s advice to "use any hole" is to simply make it easier and more accessible. And it’s excellent advice if you’re going to do it for 20-30 mins a day. There will only be problems if mouth breathing becomes habitual (like it did for me).

The Breathing 4.1.1. - Harder Breathing Techniques and Molecules of Air

 

Welcome to the second edition of "The Breathing 4.1.1."

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

 
 

 
 

4 THOUGHTS

1. We Don’t Need Harder Breathing Techniques

I recently finished the two-part interview with David Bidler on the Bravest Podcast. I highly recommend listening to both episodes. My favorite idea from David was this: We don’t need harder breathing techniques, we need to apply simple breathing methods to harder challenges. Well said.

Episode 1

Episode 2

2. HHPF High School Slow Breathing Program

Speaking of using simple breathing practices in hard situations, the Health & Human Performance Foundation (HHPF) partnered with Girard High School to implement a slow breathing program for the students. The program improved the students' tolerance to CO2 and decreased their anxiety. Pretty amazing stuff.

3. Relaxation Breathing - A Way to Lower Blood Glucose

There have been two studies examining a breathing technique called "Relaxation Breathing." I don’t hear much about it in the breathing community, but it appears to be helpful for lowering blood glucose. Here’s the method:

Inhale 2 Seconds, Exhale 1 Second
Inhale 2 Seconds, Exhale 2 Seconds
Inhale 2 Seconds, Exhale 3 Seconds
… (Exhale keeps getting longer) …
Inhale 2 Seconds, Exhale 10 Seconds

The progressively longer exhale is both relaxing and challenging near the end. I sometimes practice it when falling asleep. Give it a shot and see what you think.

If you’re interested, here are the two studies:

Relaxation breathing significantly lowers blood sugar after an oral glucose tolerance test

Slow breathing improves blood sugar by reducing body’s endogenous production of glucose

4. Oxygen Advantage + Yoga = High Altitude Yoga

My wife and I put together a class that combines yoga and breath-hold techniques from the Oxygen Advantage®. We’re calling it High Altitude Yoga™.

We’re holding a combined Virtual Masterclass where I teach the breathing principles and she teaches the yoga. If you’ve been in the breathing world for a while, the breathing concepts will not be new to you. But, combining them with yoga is both fun and challenging (we’ve had SpO2 drops in the mid-to-low 80s).

It’s going to be July 18th from 9:00 - 11:00 a.m. Eastern on Zoom. I hope you’ll join us!

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.

Can Overbreathing Cause Osteoporosis?

 

Life-transforming ideas have always come to me through books.” - Bell Hooks

 
 
 
Overbreathing_Osteoporosis_1_New.png
 
 
 

This week, I want to look at a few fascinating passages on overbreathing from “Breath: The New Science of A Lost Art.”

Let’s start with James Nestor’s insight into tissue hypoxia (my bold for emphasis):

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.

So James is saying that tissue hypoxia itself is not the problem with overbreathing. The damage occurs because of the body’s response to prevent tissue hypoxia from happening.

Overbreathing and Cell Metabolism

Aerobic = “With Oxygen”

Anaerobic = “Without Oxygen”

This damage occurs partially because of sustained anaerobic metabolism. We have all probably heard of aerobic and anaerobic exercise. Slow and steady is typically aerobic, fast and intense is usually anaerobic. We don’t have to think about it. When we push ourselves, our oxygen supply can’t keep up, and our body naturally switches to anaerobic metabolism.

This anaerobic switch creates a more acidic local environment, which will help release oxygen from the hemoglobin and help restore aerobic energy production.

But, with chronic overbreathing, this aerobic balance cannot be achieved.  So your cells are running as if you’re always doing high-intensity training…not the most efficient way to spend your day.

But that’s not even the worst part of overbreathing.

Restoring pH Balance Causes the Real Damage

The body is always trying to find balance, and this is especially true for pH. Blood pH is kept in a tight range (around 7.4) to allow the body to function correctly.

When we chronically overbreathe, we offload too much carbon dioxide, which increases pH. The body compensates through a process called “buffering,” where the kidneys begin releasing bicarbonate into the urine to restore pH balance. The real damage comes from what bicarbonate takes with it:

This occurs because as bicarbonate leaves the body, it takes magnesium, phosphorus, potassium, and more with it. Without healthy stores of these minerals, nothing works right: nerves malfunction, smooth muscles spasm, and cells can’t efficiently create energy.” - James Nestor

Overbreathing Weakens Our Bones

All of which leads us to how overbreathing can contribute osteoporosis:

Constant buffering also weakens the bones, which try to compensate by dissolving their mineral stores back into the bloodstream. (Yes, it’s possible to overbreathe yourself into osteoporosis and increased risk of bone fractures.)” - James Nestor

Alright, let’s break these steps down to see how this happens:

  1. Overbreathing offloads too much carbon dioxide, preventing adequate oxygen delivery to the cells.

  2. The cells compensate with chronic anaerobic metabolism.

  3. The kidneys compensate by excreting bicarbonate into the urine to balance pH.

  4. The excretion of bicarbonate “steals” important minerals from the blood.

  5. The bones then compensate by dissolving minerals back into the blood, which weakens them.

It is simultaneously amazing and scary what our bodies are capable of.  

There is Always Good News

Although this negative feedback loop is alarming, there is a way to prevent or reverse it: Stop overbreathing.

And the best way to do that? Breathe through your nosebreathe slowly, and breathe slightly less than you think you need.

In good breath,
Nick

Lack of Oxygen Might be the Root Cause of Diabetic Complications

 
 

Since we cannot know all that there is to be known about anything, we ought to know a little about everything.- Blaise Pascal

 
 

 
 

People with diabetes are at an increased risk of cardiovascular and autonomic problems. Diabetics also display altered respiratory control, for example, showing depressed (or enhanced) chemoreflexes.

However, previous studies have never examined these two aspects in an integrated fashion.

Integration Over Isolation

The problem with separately studying these systems is that the results might not be independent. For example, if a study shows that diabetics have decreased respiratory control, it might conclude that this is from diabetic nerve damage.

Likewise, if a study shows that cardiovascular function is depressed, it might also conclude that this is due to diabetic nerve damage.

However, if we study them together, we might find that there is a reciprocal relationship. Maybe the respiratory problems are causing cardiovascular issues? Perhaps it’s the other way around?

This study takes that approach and has some pretty remarkable conclusions.

Integrated cardiovascular/respiratory control in type 1 diabetes evidences functional imbalance: Possible role of hypoxia

(Click Here to Read Full SummaryI don’t say this often, but please read this one if you have diabetes)

Published in the International Journal of Cardiology, 2017.

In forty-six type-1 diabetics and 103 age-matched controls, they measured baroreflex sensitivity (BRS) as a marker of cardiovascular function and chemoreflexes as a marker of respiratory control.

Chemoreflexes estimate how sensitive you are to increasing CO2 (hypercapnic chemoreflex) and decreasing O2 (hypoxic chemoreflex).

The Hypothesis: If BRS and chemoreflexes are reduced, this would suggest diabetic nerve damage. However, if some are reduced while others are elevated, this reciprocal relationship might be showing autonomic dysfunction instead of diabetic nerve damage.

This is such an important distinction. “Damage” implies that the damage is done. “Dysfunction” implies that we could make it functional again.

Diabetics Have Worsened Cardiovascular and Respiratory Control

The results showed that subjects with diabetes had a lower BRS than the controls. They also had a suppressed hypoxic chemoreflex. However, they had an elevated hypercapnic chemoreflex. (Remember their hypothesis: if it was nerve damage, both of these chemoreflexes would be reduced.)

Interestingly, the diabetics also showed a lower oxygen saturation. And, they also had relatively high HbA1c’s (an average of 8.19%). A high HbA1c will decrease oxygen delivery to the tissues and cells.

Tissue Hypoxia is at the Root of Diabetic Complications

The reduced oxygen saturation and high HbA1c suggest a resting state of tissue hypoxia in diabetes. Over time, we become “numb” to this, which explains the decreased hypoxic chemoreflex.

The body compensates with an up-regulated hypercapnic chemoreflex, which leads to chronic activation of the sympathetic nervous system (fight or flight).  Chronic sympathetic activation then suppresses our cardiovascular control.

It’s a vicious cycle with negative long-term implications:


 
 
Root_of_Complications_Cycle.png
 
 

Dysfunction, not Damage: A Silver Lining

“We show in the present study that what is normally called ‘autonomic neuropathy’ could be in many cases a functional condition of sympathetic activation, driven by many factors, one of which seems to be resting hypoxia.”


This is all actually good news.  Their results suggest that diabetic autonomic imbalance is mainly functional and not related to nerve damage.  In fact, the authors suggest that this imbalance likely leads to nerve damage, rather than being the result of it. Therefore, therapies targeting cardio-respiratory control could help reverse/prevent diabetic complications if caught early enough.

Break Out Your Slow Breathing Hammer

What are these therapies? One is slow breathing. Slow breathing will immediately improve cardiovascular and respiratory reflexes. It will also enhance oxygenation (when breathing through the nose).

I hate sounding like all I have is a “slow breathing hammer,” but it is just too important not to stress over and over again.

Here’s to taking the first step toward protecting our long-term health as diabetics.

In good breath,
Nick


P.S. A great podcast was recently released with James Nestor, author of the soon-to-be-released book: “Breath - The New Science of a Lost Art”. (The book looks terrific, so I pre-ordered my copy about a week ago.)

You can basically learn everything you’ll ever need to know about breathing in this quick 35-minute interview. I loved it.

Listen to the podcast here.
