4 THOUGHTS

1. The Great Synchrony Between Breath, Heart, and Brain

“We term this phenomenon the great 10 second synchrony between breath, heart and the brain.”
– The Brain's Resonance with Breathing

This 2019 study found that slow breathing, particularly at 6 breaths a minute (a 10-second cycle), rapidly synchronizes breath, heart, and brain rhythms, providing insight into how slow breathing exercises may enhance mental and emotional well-being 👏

P.S. As always, if you want to nerd out on the full review, check out the Breath Learning Center. We now have reviews of 51 papers, 45 books, and 552 daily messages to help you live better as a mixed mindful artist (and we’re just getting started 😊). We currently have 86 active members…I’d love for you to join us.

2. Get the Best of the Mind: Now Enough Robust Science

“There is now enough robust science to show that mastering the simple movements needed to control the rate, depth and route by which you get air into your body can become a handy tool to steer thoughts and feelings in useful ways. Mastering this range of bodily movements can allow us to dial into the workings of the brain and the rest of the body, change the settings of both and get the very best out of the mind.”
– Caroline Williams, Move

👏 👏 👏

3. Three Random Thoughts on Breathing

1. All life needs to move, and the lungs and airways are perfectly designed to optimize air motion in support of life.

2. A breath practice is a tool—but not a requirement—for a good life.

3. The most common mistake in breathing is using the nose, lungs, and diaphragm, but not the heart.

4. How to Not Get Upset when a Real Trial Comes

“Simply by maintaining a sense of humor and humility, we can teach the mind not to get upset even when a real trial comes.”
– Eknath Easwaran, Conquest of Mind

This one certainly passes the real-life test for me 😊. Give it a try this week and see how it goes.

Hey,

Here are four thoughts, one quote, and one answer for this week.

I hope you enjoy!

4 Thoughts

1. Why We Should (and Should Not) Care About HRV

“Over the years we've experimented with many different types of physiological and psychological measures. Heart rate variability (HRV) patterns… have consistently emerged as the most dynamic and reflective of our inner emotional states.”
- The Heartmath Solution

I’ve been on an HRV kick lately. And although I’m fascinated by the physiological implications of it—its correlation with disease and diabetes, its impact on stress, and so on—here’s another reason we should care: It’s the “most dynamic and reflective [measurement] of our inner emotional states.”

Of course, this makes perfect sense, as our emotional states impact our physiology, and vice-versa. HRV gives us an index for them all, which is why we should care about it.

But, we should also remember that high HRV isn’t the end goal. It’s the positive states associated with high HRV we’re after.

So here’s to using slow breathing to maximize HRV while (paradoxically) remembering that HRV is not the end goal.

Related Quote: “‘When a measure becomes a target, it ceases to be a good measure.’ Measurement is only useful when it guides you and adds context to a larger picture, not when it consumes you.” - James Clear, Atomic Habits

P.S. Huge thanks to Crussen for The Heartmath Solution. After taking his genuinely incredible Heart Coherence class, I contacted him, and he said Heartmath helped inspire it. I immediately grabbed the book and loved it.

2. The Positive Breathing-Relaxation Feedback Loop

“Slow breathing techniques with long exhalation will signal a state of relaxation by VN, resulting in more VN activity and further relaxation.”
- Frontiers in Human Neuroscience , 2018

Here’s a positive feedback loop we can celebrate: Slow breathing sends a message of relaxation via the vagus nerve, which increases vagal activity, further enhancing relaxation. Thank you, complicated physiology.

Practically, this is why when you start your slow breathing practice, you don’t feel much at first, but after a few minutes, you feel like a different person. You’re experiencing this positive breathing-relaxation feedback loop in action.

Complex science. Simple to experience.

Give it a shot today.

Related Quote: “Not only does VN control heart rate and slow deep breathing, slow respiration rates with extended exhalation could also activate the PNS by VN afferent function in the airways. This is a form of respiratory biofeedback.” - Same paper as above

3. A Wealth of Health | Breathing: Misconceptions and Tips (and Wim Hof’s Mastery)

“Taking control of the breath — consciously thinking about the unconscious respiratory mechanism — is the first step to improving a plethora of everyday struggles and habits.”
- The Breeze, Breathing: Misconceptions and tips

I picked that quote because it goes perfectly with Thought #4 below on Lucid Breathing. But the article is packed with information (and name drops, 😂). It covers a lot of ground, somewhat disjointedly, but I think you’ll enjoy it.

My favorite part was a reminder of something I often forget: That Wim Hof is a master of the breath (and marketing). Although his method frustrates many in the breathing community, James Nestor nailed it in this article:

“Everyone thinks that Wim Hof is breathing ‘Wim Hof breaths’ all the time,” Nestor said. “He’s not. He’s breathing like that for 20 minutes, and the rest of the time he’s breathing really slowly, and he’s humming.”

Enjoy!

4. Are Lucid Breathers the Future of Evolution?

“It seems to be only around 20 to 30% of the population are actually natural lucid dreamers…Maybe those 20 to 30% of people who do lucid dream are at the forefront of hominid evolution, and they are going to be the next species of preference. We just don't know.”
- Matthew Walker, Ph.D.

Maybe the same is true of lucid breathers? Interestingly, Nature made it difficult to control our dreams. It made it simple to control our breath—though most of us sleep right through it.

But control over our breath was not an accident. As Belisa Vranich and Brian Sabin tell us in Breathing for Warriors, “It's an invitation, an opportunity to take part in our own nature and evolution.”

So wake up in your breath. Use it to control this dream we call living.

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!

4 Thoughts

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.

Related Quote: “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.” - James Nestor, Breath

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.
