The Breathing 4.1.1. - Breathing That Makes You Smarter

Happy Monday and welcome to another edition of "The Breathing 4.1.1."

Below, I share 4 thoughts, 1 quote, and 1 answer (think "Jeopardy"). Enjoy!

4 THOUGHTS

1. Why Increasing Your CO2 Tolerance Just Makes Sense

i. Carbon dioxide is your primary stimulus to breathe. When you feel breathless or air hunger, that is due to high levels of CO2, not low levels of oxygen.

ii. Carbon dioxide helps you use oxygen more efficiently via the Bohr effect.

Therefore, being able to tolerate more CO2 just makes sense. You’ll delay the onset of breathlessness while simultaneously improving oxygen delivery.

2. Should You Be Doing Breathing Exercises All Day?

Not in my opinion. The goal of all of this "breathing stuff" is to reset your breathing to healthy levels so you don’t have to think about it all the time.

3. Can Your Breathing Make You Smarter?

Nasal breathing synchronizes brainwave oscillations in the piriform cortex, amygdala, and hippocampus. This coherence improves cognitive function when compared to mouth breathing.

4. If You or Your Child Suffers from This Condition…

If you’re reading this, the adverse health effects of mouth breathing probably seem obvious to you by now. But maybe not everyone else.

That’s why it is always great to see an article about it in a more mainstream publication like ScienceDaily. The final paragraph is both wonderful and comical (without trying to be):

"At this time, many health care professionals are not aware of the health problems associated with mouth breathing. If you or your child suffers from this condition, speak with a health care professional who is knowledgeable about mouth breathing."

P.S. Nostalgia.

Nasal breathing synchronizes brain wave activity and improves cognitive function

Last week, we discussed century-old ideas about nasal breathing and mental function. I said that current science is beginning to catch up. Here’s how.

Modern Science Supports 100 Year-Old Observations

A study published in 2016 in The Journal of Neuroscience showed that nasal breathing is intimately connected to brainwave oscillations, emotional recognition, and memory retrieval.

Intracranial EEG measurements showed that nasal breathing synchronizes brainwave oscillations in the olfactory bulb, the hippocampus, and the amygdala. When breathing was switched to the mouth, this coherence disappeared.

In a follow-on experiment, they showed participants pictures of faces expressing fear or surprise. They had to pick which one it was as fast as they could.

Not only did the nasal breathers outperform the mouth breathers, but they also found that responses were quickest during inhalation versus exhalation. The participants also had more accurate memory retrieval during nasal inhalation.

Taken together, their results indicate that nasal breathing acts to organize brainwave oscillations and improve cognitive functioning.

These results also help explain Guye’s theory about nasal breathing and mental function. That is, they support the quote “Shut your mouth and save your brain.”

Breathing is More Than Just Gases

These results imply that breathing is about more than just about gases. Breathing acts to synchronize brain activity and enhance cognitive function…but only when performed through the nose.

In good breath,
