4 THOUGHTS

1. Understand This, and You Will Understand Breathing

Breathing information is often contradictory:

  • Wim Hof tells you to breathe more oxygen.
    Patrick McKeown tells you to breathe less.

  • Oxygen is your body’s most important energy source.
    But the exhale is the most important part of the breath.

  • You need to teach yourself to tolerate higher levels of carbon dioxide.
    Carbon dioxide also causes fear in people who literally can’t feel fear.

  • Lung capacity determines longevity.
    But you also shouldn’t take big breaths.

  • And on & on

To understand breathing, you must accept that all of these are right, and all of them are wrong. It depends on the circumstance.

Despite its simplicity, breathing is one of the most complex functions in the human body. Blanket statements on "right or wrong" simply cannot be made without context. We must embrace the contradictions.

2. Should You Be Breathing Even Slower?

A study published in 2006 found that resonance frequency was inversely correlated with height. That is, the taller you are, the slower you need to breathe to synchronize your heart rate, breathing rate, and autonomic nervous system.

In their excellent book, The Healing Power of the Breath, Richard Brown and Patricia Gerbarg give this specific recommendation: "For people who are over six feet tall, the ideal resonant rate is three to three and a half breaths per minute."

So, if you’re over six feet tall, you might find that breathing slower than the typical recommendation of 5-6 breaths per minute works better for you. I fall into that category, and I’ve found 3 - 3.5 breaths per minute (currently 7 sec inhale, 11 sec exhale) to be my sweet spot.

3. What is Hyperventilation?

"Respiratory alkalosis is caused by hyperventilation or a respiratory rate in excess of that needed to maintain normal PCO2." - Essentials of Pathophysiology, pg. 205

"Hyperventilation is a term that describes breathing beyond that which is required to meet the metabolic needs of the body as reflected in the production of carbon dioxide." - Respiratory Physiology, pg. 128

Here are two different textbook definitions of hyperventilation. It’s actually pretty straightforward. And, as you can see, it doesn’t involve huffing and puffing. Thus, we can hyperventilate without even knowing it.

Two easy ways to check if you are overbreathing are the BOLT score and the CO2 Tolerance Test.

Two easy ways to fix it are to breathe through your nose and make your breathing quiet while at rest.

Thanks to 411 reader W.H. for inspiring this thought.

4. Is Breathing Woo-Woo?

It fascinates me that breathing, your body’s most important function, has kind of a "woo-woo" reputation. It shouldn’t. There is a mountain of scientific evidence showing its efficacy for health and wellness. For example, I have reviewed over 80 scientific papers, and HHPF seems to post a new one every day.

But you actually don’t need any of the science. Here is the quickest way to determine for yourself:

Hold your breath.

I think you will agree "breathing" isn’t woo-woo after only a few seconds.

Thanks to fellow breathing nerd R. vdC. for inspiring this thought.
