1. Here is the Fastest Way to Achieve Well-Being

So what is the fastest way to achieve well-being? It is so close to you that it can easily be overlooked. Your breath.  A rapid and reliable pathway into your nervous system, dedicated to helping you regain your optimal state.

- Emma Seppälä, Ph.D., The Happiness Track

This is beautifully and perfectly said. Nothing to add here 🙏

2. On Sailboats, HRV, and Developing Your Inner Resources

Developing inner resources is like deepening the keel of a sailboat so that you're more able to deal with the worldly winds—gain and loss, pleasure and pain, praise and blame, fame and slander—without getting tipped over into the reactive mode. Or at least you can recover more quickly.

- Rick Hanson, Ph.D., Neurodharma

Although Dr. Hanson is talking about inner resources in general, this is an excellent analogy for why improving HRV via slow deep breathing is so helpful: it’s like deepening the keel of your physiological sailboat.

You will still be hit by life’s storms, but with higher HRV, you’ll remain steadier and recover quicker. We could say, then, that deep breathing = deep keel.

3. Slow Breathing for Better Blood Flow

“When [the small] blood vessels are relaxed, more blood can flow freely through them. When they become constricted, the same amount of blood flows through a narrower space, increasing your blood pressure.

- Inna Khazan, Ph.D., Biofeedback and Mindfulness in Everyday Life

Slow breathing activates the calming parasympathetic nervous system, which relaxes the small blood vessels, lowers blood pressure, and improves blood flow.

This is a vital benefit of slow breathing because better blood flow is necessary for, well, just about everything (especially if you have diabetes).

So if you feel so inspired, give it a shot. Sit and breathe at 5-6 breaths/min for 2 min. Feel for yourself the rapid boost in blood flow to your hands and/or feet.

***

P.S. I’ve had cold hands & feet for as long as I can remember (thanks, diabetes). Although it’s improved considerably, one of my favorite things about slow breathing is the warmth I feel in them during and after my practice.

4. Control, and How to Focus on a Fuller Life

Even if you don't have control over the outcome of the stressful situation, you may be able to exert some control over its impact…You can't always control what you feel or think, but you can control what you do. Focus on living a full life even though you don’t have [fill in your issue]…

- Melanie Greenberg, Ph.D., The Stress-Proof Brain

When nothing seems to work, my blood sugars still go crazy, my insulin sensitivity is off, or I don’t sleep well, I always have the breath. I have something I can control, that gives me control.

It helps me focus on living a fuller life, and I hope it does for you too 🙏

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.

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.

Nerdy Warriors of the Breath, Investing, and a Useful Look at HRV

Greetings,

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

Enjoy!

 
 

 
 

4 Thoughts


1. A Practical Look at HRV and Resiliency

Resilience is the ability to return to normalcy, according to Jen Baker, director of athletics and recreation at John Hopkins University, a graduate of the US Naval Academy. It's your ability to bounce back and thrive, replace worry with objective things, to navigate and take steps forward.

- Belisa Vranich & Brian Sabin, Breathing for Warriors

Slow breathing significantly increases heart rate variability (HRV) and, subsequently, increases resiliency. This has been shown time and time again. But, from a practical perspective, what does it mean to “increase resiliency?”

Does it mean you’ll never experience stress or anxiety again? No, certainly not. What it means is that the stressors won’t feel as severe and, as Jen Baker says, that you’ll bounce back faster. The stress is the same. You’re different.

So here’s to not trying to escape the world and its stressors, but instead having the tools—one being slow breathing—to bounce back to normalcy faster.

Related Quote:By modulating the stress response via vagal stimulation from conscious breathing exercises, people can bolster their resilience to all forms of negative stressors; diabetes is no exception.” - Evan Soroka, Yoga Therapy for Diabetes

2. Where Are You Investing Your Breathing: GameStop or Real Estate?

Slow breathing methods can be “life-changing,according to James Nestor. But, “they can also take a while, especially for those with…chronic conditions.” On the other end of the spectrum, he says methods like Tummo restore balance with a “violent shove,” which can also be helpful for some.

So how do you know which is right for you?

I liken it to investing. Slow, nasal breathing is like putting your money in real estate or an index fund. It’s pretty safe. There will be fewer ups and downs, and you’re almost guaranteed a positive return.

The “violent shove” techniques, on the other hand, are like investing in GameStop or crypto. You might see some incredible benefits in just one day. But, you also risk a significant loss the next if you're not diligent with it.

So the question is: Are you looking for short-term gains or long-term compounding? Are you timing the market or playing the long game? Maybe you want to have a “diversified portfolio” : ) There’s no right or wrong answer. Only you know which approach is right for you.

3. “'Email Apnea' Is a Real Thing-Here's How to Stop Holding Your Breath While Working (and Feel Less Stressed)”

Learning (and really practicing) basic breathing techniques can also help reverse the effects of email apnea; it'll help you improve awareness of your own breath and breathing habits and teach you how to breathe more easily during times of stress.

- Real Simple, ‘Email Apnea’ is a Real Thing

This article provides an excellent summary of email apnea and some practical things you can do to reduce how often it occurs. Or, at the very least, to help reverse some of its harmful effects.

As someone who still (after years of a daily breathing practice) occasionally experiences this, I thoroughly enjoyed the read. I hope you do too!

4. Nerdy Warriors of the Breath

The old-school philosophers knew it was really hard to live in integrity with our highest ideals. They told us we needed to be WARRIORS of the mind, not mere librarians of the mind.

- Brian Johnson

Meaning we have to live our philosophy, not simply recite it to other people. The same is true with breathing. But, with breathing, both are critical.

We have to be warriors of the breath. We have to live it and practice it, in easy and difficult circumstances. But, we also need to be librarians of the breath.

We need to have the science ready in our back pocket. We need to intrigue people with the experience, then back it up with the science, or vice-versa.

So here’s to being nerdy warriors of the breath, accomplishing great things with our practice, and then explaining the physiology of how it worked : )

Extra Thought: Breathing I’m Exploring

I try my best to be a breathing warrior, and I practice every single day. I don’t share too much about it because everyone’s practice is their own. But, here are a couple of new things I’ve tried recently:

Breathwrk App: I’ve been having fun doing 1-3 min of each breath they offer. I use it sporadically throughout the day just to try something different. My three favorite breaths so far are:

  1. No Worries

  2. Clear Mind

  3. Calm

Open: I’ve also taken a few on-demand breathwork classes through Open. I usually enjoy being in control, but I have genuinely loved these classes. Here are my two favorites (thanks Crussen!):

  • Heart Coherence (this one was truly incredible)

  • Symmetry (box breathing w/music—an excellent mix)

Here’s to never-ending growth, learning, and exploration of the breath.
