How I Trained for Altitude and Why We All Benefit from Breath Training

 
 

Listen Instead of Reading


 

Autonomic Neuroscience says slow breathing is for diabetes & hypertension.

Harvard Medical School says yogic breathing is for stress.

And Tibetan Yoga says breath training is for everyone.

Let’s see how…

1. How I Trained for High Altitude (it’s not what you might think)

I thought, “I’m The Breathing Diabetic. I better be able to handle some altitude.”

But I didn’t train how you might think. Of course, I initially started with more breath holds. But I realized that the issue at altitude is lower air pressure.

- How I Trained for High Altitude Blog Post

This one was slightly too long to fit in as a “Thought,” so I made it a really short blog post.

Give it a read to learn my somewhat odd training method for my recent hike up to 13,200 feet…and to see if it actually worked (pictures included).

Please respond to this email if you have any thoughts on my reasoning…it was my first time at altitude, so I’d appreciate any feedback or thoughts you have.

2. Slow Breathing for Diabetes and High Blood Pressure

Even in already well controlled diabetic patients, guided breathing had beneficial influences on cardiovascular autonomic control and a measurable impact on BP control.  It enriches available options for non-pharmacological blood pressure…reduction.

- Effects Of Guided Breathing On Blood Pressure And Heart Rate Variability In Hypertensive Diabetic Patients

According to Johns Hopkins, approximately two-thirds of adult diabetics have high blood pressure or take medication for it. And people with diabetes and hypertension are 4x more likely to develop heart disease.

Fortunately, this study found that just 12 minutes a day of slow breathing (with no changes to medication) led to significantly lower blood pressure, increased heart rate variability, and a reduced spontaneous breathing rate (indicating reduced sympathetic arousal).

All of which led to this remarkable final statement: “If consistently used, guided breathing enhances restoration of physiological autonomic balance in patients with diabetes and hypertension.” Amen 🙏

Here’s to controlling our breath to control of our blood pressure, today.

3. Harvard Medical School: “Yogic Breathing Improved University Students' Response to Stress”

When we anticipate a stressful situation, our breathing and heart rates naturally go up…but the yogic breathing group seemed to show protection against that type of stress. Their heart rate increased only slightly when they knew a stressful situation was coming.

- Yogic breathing improved university students' response to stress

Enjoy this excellent and quick write-up showing that yogic SKY breathing can significantly reduce the stress response. It’s from the Beth Israel Deaconess Medical Center, a world-class teaching hospital of Harvard Medical School.

The next thought builds off of this idea of “protection against stress”…

4. What Turbulence Can Teach Us About Breathing

When you’re flying and hit turbulence, you’re told to put on your seatbelt.

It’s reactive.

It’s similar to when turbulence hits in our lives. We react. We start eating healthy or meditating or exercising more.

But a regular breathing practice is proactive.

It helps you avoid turbulence altogether.

Or, if you can’t avoid the turbulence, it’s like your seatbelt. You’re already fastened in. You don’t need to rush back to your seat. You’re ready.

How Breathing Improves HRV, Sleep, and “Keep Breathing. That’s the Key”

 
 

Listen Instead of Reading


 

Greetings,

I realized that last week marked one year of The Breathing 411—and 2.5 years of sending a weekly breathing newsletter. 🤯

Writing this newsletter is my favorite thing in the world to do, so thank you for reading, sharing, and practicing these ideas.

Alright, here are 4 thoughts, 1 quote, and 1 answer for this week.

Enjoy!

1. The Mechanisms of How Breathing Improves HRV

Inhalation causes an immediate rise in heart rate, followed (∼5 s) by increased blood pressure and baroreceptor firing. Exhalation results in an immediate decrease in heart rate followed (∼5 s) by decreased blood pressure and baroreceptor firing.

- A Practical Guide to Resonance Frequency Assessment for Heart Rate Variability Biofeedback,
Frontiers in Neuroscience

Have you watched the Huberman Lab video showing how breathing immediately impacts heart rate? Check it out. The above passage explains how that process goes on to improve HRV.

Specifically, it’s that ~5-second lag between the rise and heart rate and rise in blood pressure that’s critical. And it’s this lag that makes breathing at a 5in/5out rhythm so beneficial (although it’s slightly different for everyone).

When we breathe like this, the messages from our breath and blood pressure synchronize, increasing their amplitude and increasing HRV.

Thus, there’s to magic behind how slow breathing improves HRV. It’s simply a harmony of body messages, which increases efficiency and, subsequently, improves resiliency and overall health.

2. Breathing’s Version of Powered In, Unplugged, and System Restarts

  • Nasal breathing is like having your computer plugged in. You’re getting a constant supply of energy via your power chord (nose and nasal airways).

  • Mouth breathing is like unplugging from the charger. Sometimes it’s needed, and you can make it for some time, but eventually you’ll run out of juice.

But suppose you keep your computer plugged in 24/7, even at night when you close your laptop (via mouth tape).

What happens in that case? Well, even then, you’ll eventually have too many things running. You’ll need a restart.

Methods like Wim Hof/SKY/Tummo serve as this restart for your nervous system. They clean out all the junk, allowing you to return to your baseline.

Here’s to using our breathing to optimize our energy and meet whatever demands our systems have.

3. “Can Breathwork Help You Sleep? An Expert Explains”

If you want to engage in breathwork for sleep, don’t get too hung up on the details. The key is to slow down your breath and really direct it to your belly using your diaphragm.

- Can Breathwork Help You Sleep? An Expert Explains

In this article, Molly Atwood, an assistant professor of psychiatry and behavioral sciences at Johns Hopkins University, explains why deep breathing is so helpful for sleep. It’s super quick and practical—I loved it.

It was especially refreshing that there was nothing fancy or complex: “It’s not a super complicated thing to practice,” she says. “I think it would be hard to find something that would steer you completely wrong.” Amen, and enjoy!

4. Turning Breathing Knowledge into Breathing Wisdom

But not until that moment…did that knowledge become wisdom, that is, become how I felt.

- Alex Lickerman, MD, The Undefeated Mind

What a perfect distinction for when knowledge becomes wisdom: It’s that moment when something you know becomes how you feel.

Here’s to turning breathing knowledge into breathing wisdom through continuous learning, practice, and insights.

P.S. Dr. Lickerman also describes an insight as “that most mysterious of experiences in which knowledge takes root in a person’s psyche and alters what he believes and therefore how he behaves.” Love it.
