1. Yoga Breathing Helps Cancer Chemotherapy Symptoms (+ free science 411)

“Pranayama may be helpful for improving sleep disturbance, anxiety, and mental QOL [quality of life] among patients undergoing chemotherapy.”

- Dhruva et al. (2012)

This is an inspiring pilot RCT that found that a simple breathing practice can help reduce the harmful side effects of chemotherapy.

The study wasn’t perfect and pranayama didn’t magically solve all their problems. But it helped. That’s all we can hope for.

I’ve also made the Science 411 on this paper free for everyone 🙏

P.S. Some of you may know that I lost my sister to cancer. I remember how hard chemo was for her. So—even as someone obsessed with breathing—it’s difficult to review a study suggesting that patients should “just breathe,” and it will help. But this study was done over 1 year, and the classes had almost 100% attendance, making me believe the patients found it valuable, which matters the most.

2. Breathing is the Heart of All Life

“In addition, the mental component of breath is a sense of rhythmic expansion and contraction, and I think that connects us to every other living thing because all living organisms breathe. So that same rhythm is at the center of the heart of all life.

- Andrew Weil, MD, Breathing: The Master Key to Self Healing

Just an elegant reminder that breathing connects us to all living things. It’s the heart of all life 🌎

3. Optimal Mouth Posture at Rest

“The correct oral posture, the one that appears most conducive to jaw development, is (when not speaking or eating) holding the mouth closed with teeth in light contact and the tongue resting on the roof of the mouth.”

- Sandra Kahn and Paul Erhlich, Jaws

I struggle following these guidelines all day, but here is the most succinct description I’ve found on optimal mouth posture at rest.

Maybe it will inspire you to notice your mouth posture more today 🙏

4. It’s Not the Highs; It’s Who You Become

“It's not the highs along the way that matter. It's who you become.”

- Daniel Goleman & Richard Davidson, Altered Traits

 

That’s a perfect rule of thumb for any contemplative practice (like breathing).  Experiencing highs & improving biomarkers of health and wellness is meaningful, but it’s who you become that matters most.

1 Quote

If you would foster a calm spirit, first regulate your breathing; for when that is under control, the heart will be at peace; but when breathing is spasmodic, then it will be troubled.”
— Kariba Ekken

More Loving Potential, Cold Showers, and the Healing Power of Mind

1. How to Improve Your Loving Potential

High vagal tone, then, can be taken as high loving potential. … Compared to people with lower vagal tone, those with higher vagal tone experience more love in their daily lives, more moments of positivity resonance.”

- Barbara Fredrickson, Love 2.0

High vagal tone = high loving potential. That’s pretty awesome.

And fortunately, we can immediately increase our vagal tone with just a few minutes of slow breathing. We can also improve our baseline vagal tone with just 10-20 minutes of slow breathing every day.

So breathe less, love more.

2. Do Cold Showers Improve Breathing Efficiency? (my guess is yes)

“It’s very simple. A cold shower a day keeps the doctor away.”

- Wim Hof, The Wim Hof Method

Wim also tells us that when we practice cold exposure, we exercise our “sixty-two thousand miles of veins, arteries, and capillaries,” ultimately improving blood flow.

This matters because we need adequate blood flow to get oxygen and nutrients to the cells. Thus, better blood flow = better breathing.

So, in addition to keeping the doctor away, we might guess that a cold shower a day keeps us breathing in an efficient way…

Learn more cold benefits in the Book 411 and Science 411s available as part of the Wim Hof Wisdom Bundle.

3. One Reason (of many) We Began Habitually Mouth Breathing

There are lots of reasons why mouth breathing is so prevalent, but this is one I hadn’t heard that makes a lot of sense:

“Of course it's often tough to avoid mouth breathing, especially since we started living much of our lives indoors. … Enclosed spaces are areas where allergens (substances that cause allergies) tend to concentrate. … In turn these allergy-friendly environments increased the odds that children would early on develop upper respiratory problems.”

- Sandra Kahn & Paul Erhlich, Jaws

4. A Small Thought on Adding Meaning

Your birthday, January 1st, or any holiday are all just ordinary days.

What makes them so fun is that we add meaning to them.

And what’s amazing is that we can use this power of meaning anytime we want.

We can make an ordinary breath practice extraordinary by adding meaning to it.

We can make anything extraordinary by adding meaning to it.
