The way you breathe might affect your insulin sensitivity. And the way you walk definitely affects your ability to withstand discomfort.

Let’s find out how…

1. Longer Exhalations are Naturally Relaxing

“It's helpful to extend your exhalations because the ‘rest and digest’ parasympathetic nervous system handles exhaling while also slowing your heart rate. So, longer exhalations are naturally relaxing.”

- Rick Hanson, Ph.D., Neurodharma

Just a friendly reminder that extending the exhalation is one of the fastest ways to naturally relax. That is all : )

2. How Breathing Might Help with Insulin Sensitivity

“These observations demonstrate that hypoxia rapidly regulated the inhibition of the insulin signaling pathway […] During reoxygenation, the ability of insulin to stimulate phosphorylation of insulin receptor and signaling proteins was restored after 45 min.”

– Hypoxia Decreases Insulin Signaling Pathways in Adipocytes

Insulin resistance is a critical factor in diabetes and overall metabolic health. In this paper, we learn that low tissue oxygen (hypoxia) can trigger insulin resistance. Encouragingly, however, reoxygenation restored it.

This is one reason why optimal breathing is so essential for metabolic health, especially for people with diabetes. By practicing slow nasal breathing, we increase our blood and tissue oxygenation. This could potentially maintain, or even restore, insulin sensitivity.

Of course, there is no research showing that slow nasal breathing does this—no one is going to fund that study : ) But, given what we know about slow breathing, tissue oxygenation, and blood flow, it seems reasonable to hypothesize that it would help. I know have certainly noticed a difference.

3. “Role of respiration in mind-body practices: concepts from contemporary science and traditional yoga texts”

“Traditional yoga texts also suggest a solution for the imbalance in prana, through slow, deep breathing. … The beneficial effects of deep breathing are supported by contemporary science.”

- Telles et al. (2014), Frontiers in Psychiatry

I’ve shared a quote from this paper before, but if you haven’t read the full thing, it’s well worth it. It describes how modern science supports ancient yogic breathing, for example, how “Conventional physiology has found benefits of deep breathing supporting the importance given to regulating the breath in yoga.”

Another interesting idea they mention is that breathing “acts as both a top-down and bottom-up mind-body practice.” It makes perfect sense, but I hadn’t thought about it that way.

Ancient Yogic Wisdom + Modern Science = A Fantastic Read

Enjoy!

4. Finding Comfort in Breathwalking

“To take my mind off the discomfort, I settle into a respiratory rhythm. I take one step as I breathe in, then two steps as I breathe out. One step breathing in, two steps breathing out. Over and over, focusing only on the breath.”

- Michael Easter, The Comfort Crisis

Easter spent more than a month in a remote region of Alaska. And this book that came out of it is incredible—a perfect blend of science and storytelling.

Of course, this part stood out to me : )

Easter is making a ridiculous walk back to camp with a ton of weight. He naturally settles into his breath, and this gives him comfort and endurance.

As he puts it, “There's science behind this. Brazilian researchers found that people who are able to detach from their emotions during exercise, for example, not thinking about or putting a negative valence on their burning legs and lungs, almost always perform better.”

So aside from the mechanics and oxygenation, here’s another way in which breathwalking can be beneficial. It helps you detach from your emotions. As Easter tells us, you’ll “almost always perform better.” Sounds good to me.

1. On Bruce Lee, “Methods,” and Becoming Mixed Breathing Artists

“The individual is of first importance, not the system. Remember that man created method and not that method created man, and do not strain yourself in twisting into someone’s preconceived pattern, which unquestionably would be appropriate for him, but not necessarily for you.”

- Bruce Lee, Striking Thoughts

I think we can safely say Bruce Lee would be against using any one breathing “method.” He didn’t even believe there were different forms of fighting.

In fact, many consider Lee to be the original Mixed Martial Artist. Let’s follow his lead and become the first Mixed Breathing Artists.

That means we become both methodical and flexible. We focus on science and self-expression. We don’t strain ourselves to fit into a specific method; instead, we use what’s appropriate for a given situation.

Here’s to using the mixed breathing arts to conquer life’s challenges, today.

2. What Full Lotus Can Teach Us About Breathing

“Years after I had mastered the full Lotus, another teacher walked by while I was sitting, tapped on my shoulder, and gestured toward my full Lotus: ‘That is the whole problem for you.’ ”

- Larry Rosenberg, Breath by Breath

This is one of my new favorite stories. Larry Rosenberg had a teacher who thought sitting in full Lotus was essential. So, he practiced diligently and deliberately for 10 years. Finally, he could sit comfortably in it.

Then, a few years later, a different teacher saw him sitting in Lotus and told him, “That is the whole problem for you.” What one teacher said was essential, another said was his problem. His Lotus was perfect; that wasn’t the issue. It was his obvious attachment to it.

The lesson for us is that we cannot attach ourselves to any one approach to breathing (just like Bruce Lee didn’t attach himself to any single martial art).

Of course, we need to be grounded in science-based principles. But remember to be open. The method you’ve perfected might be the one that’s holding you back the most.

3. From NPR: “Just Breathe: Body Has A Built-In Stress Reliever”

“The breath isn't something Western medicine should blow off. It's a powerful tool for influencing individual health and well-being. And the best part is all the ingredients are free and literally right under your nose.”

- NPR, Just Breathe: Body Has a Built-In Stress Reliever

NPR published this article over a decade ago, but it’s still relevant today. Check it out to learn how we can use slow and fast breathing to stimulate the nervous system, and how slow breathing might change gene expression.

Enjoy the quick read!

4. The Beauty of Red Blood Cells

“These experiments revealed a novel activity of the RBC [red blood cell]: the RBC regulates its own principal function—that is, O2 delivery.”

- Extrapulmonary Effects of Inhaled Nitric Oxide

There are about 1 billion oxygen molecules on each of the trillions of red blood cells in your body. That’s a lot of oxygen. As the red blood cells circulate, they deliver this oxygen where it is needed most.

And as it turns out, the red blood cells themselves help regulate this process. Specifically, when they sense areas of low oxygen, they release a bioactive form of nitric oxide. This expands the vessels, which allows more blood flow and, ultimately, more oxygen delivery. It’s quite complex, and quite beautiful.
