4 Thoughts


1. The 3 P’s of Breathing

  1. Physiology: The impact breathing has on your body.

  2. Psychology: The impact breathing has on your mind and emotions.

  3. Philosophy: The impact breathing has on how you live your life.

P.S. You can’t have any one P without the others : )

2. A Revolutionary Finding: The Two-Way Street of Breathing and Emotions

“Lo and behold, the participants started to feel the emotions that corresponded to the breathing patterns. In other words, when they took deep, slow breaths, the participants felt calm. And when they took rapid, shallow breaths, they felt anxious or angry. The finding that we can change how we feel by using our breath is revolutionary.” * (my emphasis)

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

We know that how we feel affects our breathing. However, research tells us it’s a two-way street: We can change our breathing to change how we feel.

Quite revolutionary, indeed.

P.S. This falls into the the 1st and 2nd “Ps” above. And if you apply it regularly, then the 3rd one as well : )

3. Wim Hof vs. Wim Hof: Which of His Components is Most Important?

A 2020 study that’s still in preprints (so it hasn’t undergone peer review yet) shed light on the individual components of the Wim Hof Method (WHM).

Here’s what they did:

  • One group practiced the breathing only.

  • One group practiced cold exposure only.

  • One group practiced cold and breathing.

  • One group was trained by Wim Hof.

  • One group was trained by a researcher.

Then, all the groups were injected with endotoxin, like the first WHM study.

Here are a few of the key findings:

  • Breathing by itself reduced inflammation significantly, but did not reduce flu-like symptoms.

  • Cold by itself reduced flu-like symptoms, but did not reduce inflammation. (This doesn’t mean cold exposure doesn’t reduce inflammation in general. It just means it didn’t lessen the acute ramp-up of inflammation brought on by the endotoxin.)

  • The combination of cold and breathing reduced inflammation even more. (So, cold exposure wasn’t helpful on its own for inflammation, but added a boost when combined with the breathing.)

  • The results were the same whether Wim trained them or not (this was most surprising to me).

As a breathing nerd, this paper was super satisfying to read.

But remember it’s still in preprints, so it could turn out there was a major flaw or bad data or something. But, still fun to geek out on nonetheless : )

4. Breathing Like Journalists: Slow Breathing for Everyday Life

“I call this approach, in which you fit deep work wherever you can into your schedule, the journalist philosophy. This name is a nod to the fact that journalists…are trained to shift into a writing mode on a moment’s notice”

- Cal Newport, Deep Work

Let’s adopt this journalist philosophy to our slow deep breathing practice, fitting it into our schedules wherever we can. This will allow us to flip the switch on our physiological and emotional state anytime, anywhere (see thoughts 1 & 2).

Here’s to becoming breathing journalists, today : )

Bonus Thought: Join a Breathing Experiment

Two Simple Ways to Improve Your Sleep Tonight

Charles Dickens just walked into a hotel room. The year is 1860. As arguably the most famous author alive, you might think he set up his writing station and poured a glass of Brandy. Instead, he pulled out his compass and rearranged the place [1].

Dickens’ Odd Fix for Insomnia

Dickens believed that sleeping with his head toward the north helped with his insomnia. This sounds funny but is probably more helpful than his previous solution, which was to walk all night, sometimes covering up to 30 miles [2].

Although Dickens’ sleeping habits were peculiar, it was his keen observations of others that changed sleep science.

Joe’s Snoring and Sleep Science

In 1836, Dickens began writing The Posthumous Papers of the Pickwick Club, also known as The Pickwick Papers. In it, Dickens’ character “Joe” displayed all of the classic characteristics of sleep apnea. Joe was always tired, he fell asleep during the day, and he snored loudly.

Sleep scientists credit this work as being the first accurate observations of sleep-disordered breathing [3], recording it 120 years before the science caught up.

Modern Sleep Science Catches Up

Today, estimates of sleep-disordered breathing are, well, breathtaking. The term “sleep-disordered breathing” itself is rather generic. It covers a wide range of issues related to sleep and breathing (most commonly, obstructive sleep apnea).

However, in 1996 a review study was published that sheds light on the mechanisms that cause sleep-disordered breathing. This research helps explain why it is so common and provides suggestions as to what we can do about it.

Sleep and Breathing State-of-the-Art Review: Sleep-Induced Breathing Instability

(Published in Sleep in 1996 — Click Here to Read Full Summary)

The main conclusion from this study is that your breathing system does not work the same during sleep as it does during wakefulness.  

For example, there is less input to the muscles that keep your upper airways open, which can narrow or collapse them. This narrowing of the upper airways also increases breathing resistance. Additionally, sleep dampens the chemoreflexes that usually keep blood pH in a tight range. 

Interestingly, this “State-of-the-Art Review” concluded that carbon dioxide (CO2) could potentially help with sleep-disordered breathing. CO2 could stimulate the chemoreflexes that keep breathing steady. Additionally, CO2 is a smooth muscle dilator, which would help increase blood flow to the muscles that keep the airways open.

Two Ways You Can Start Tonight

1. Tape Your Mouth

You can start adding CO2 to your breathing tonight by taping your mouth during sleep, which will reduce breathing volume and increase CO2.

Paradoxically, while nose breathing increases resistance during the day, it reduces upper airway resistance during sleep. This small change will help you breathe better during sleep and wake up feeling refreshed and energized.

2. Breathe Less During the Day

You can also practice light breathing during the day to train your body to tolerate more CO2. By doing this consistently, you can reset your baseline CO2 back to normal values and ultimately improve your breathing during sleep.  

In good breath,
Nick

P.S. I think we all need a smile like this right now.
