4 THOUGHTS

1. Yoga Breathing, Meditation, and Longevity

“By inducing stress resilience, breath work enables us to rapidly and compassionately relieve many forms of suffering.”

Brown and Gerbarg (2009)

Here’s my take-home from this excellent narrative review 👏

Yogic breathing and meditation are complementary practices that may enhance longevity by improving nervous system health and stress resiliency, boosting emotional health, enhancing brain health, and reducing suffering associated with disasters.

2. Amazing or Dangerous? Mindful Breathing Preserves Focus After Multitasking

I’m not sure if this finding is (1) just amazing or (2) potentially dangerous, lol. But it’s too neat not to share 😊

“For instance, research at Stanford University found that if you are focused on an important project and then stop to answer a text or email, and end up browsing the web, when you finally return to your important project your focus has dimmed. It takes you some time to ramp up your concentration to the previous level. Unless you did ten minutes of mindfulness of your breath a couple of times that day—then you have little or no loss of concentration after ‘multitasking.’

– Daniel Goleman, Ph.D., Why We Meditate

3. Affecting Deep Physical and Psychological Changes

“As the breath is the link between the body and mind, it can intervene in the activities of either level. With increased awareness and control of the subtle aspects of breathing, these interventions can affect deep physical and psychological changes.”

- John Clarke, MD, Science of Breath

Just a compelling reminder of how powerful breathing exercises and simple mindful breath awareness are. Because the breath literally and metaphorically links the body and mind, such interventions “can affect deep physical and psychological changes.” 👏

4. Don’t Have Time to Breathe or Meditate? (maybe this passage will be inspiring)

“It is a truth universally acknowledged that one saves time travelling only two hours from one point to another instead of spending eight hours on the same journey. While this holds up mathematically, my experience is the opposite: time passes more quickly when I increase the speed of travel. My speed and time accelerate in parallel. It is as if the duration of a single hour becomes less than a clock-hour. When I am in a rush, I hardly pay attention to anything at all.”

- Erling Kagge, Walking: One Step at a Time

Although this passage is about travel and walking, it applies perfectly to breathing or meditation.

By taking time out of your already busy morning to meditate or breathe, you actually create more time because you slow things down.

So, instead of thinking, I don’t have time to do this, think, I create time by doing this.


1 Quote

Sometimes, you get lucky in life, when the most important thing you need to do turns out to also be the simplest. One example is breathing. Breathing is the most important thing we need to do in our lives, and for most of us, it is also the easiest thing we ever do. If you belong to the population of people who can breathe effortlessly, you are so lucky!”

4 Thoughts



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.

Each Monday, I curate and synthesize information from scientific journals, books, articles, and podcasts to share 4 thoughts, 1 quote, and 1 answer (like "Jeopardy!") related to breathing. It’s a fun way to learn something new each week.

 

The Best Way to Begin Slow Breathing

 
 

“The secret of making progress is to get started. The secret to starting is to divide your complex, overwhelming task into small, manageable tasks, and then start the first.” - Mark Twain

 
 
 

Slow breathing has many benefits. For example, it improves cardiovascular and autonomic functioning. However, as we mentioned last week, you can quickly get “lost in the crabgrass of details” if you’re not careful, which is basically what I do every day :)

For instance, there are several ways to breathe slowly. You can use equal inhales and exhales, extended exhales for more relaxation, or you can include ujjayi breathing if you’re a trained yogi.

The study I’m sharing this week examined some of these nuances to determine which is best for beginners.


Cardiovascular and Respiratory Effect of Yogic Slow Breathing in the Yoga Beginner: What Is the Best Approach?

(Click Here to Read Full Summary)

Evidence-Based Complementary and Alternative Medicine, 2013

The study had seventeen non-yoga practitioners perform several different breathing protocols:

  • Spontaneous breathing

  • Controlled breathing at 15 breaths/min

  • Slow breathing at 6 breaths/min, 5 sec inhale, 5 sec exhale (equal)

  • Slow breathing at 6 breaths/min, 3 sec inhale, 7 sec exhale (extended)

  • The above two slow breathing protocols, but with ujjayi

Measurements of baroreflex sensitivity (BRS), blood pressure, and several respiratory variables were taken during the experiment.

Most Improvements from Slow Breathing without Ujjayi

They found that slow breathing without ujjayi was the most effective at improving cardiovascular and autonomic function (as measured by BRS) and at reducing blood pressure.

However, keep in mind that these were not trained yogis. Therefore, the added effort of ujjayi likely dampened the parasympathetic response. The results would likely be different in a trained ujjayi practitioner.

Getting Started: Breathe at a Ratio That Is Comfortable For You

All of their results revealed that slow breathing with an equal inhale-to-exhale ratio performed best. However, the differences between the balanced and extended exhale techniques were small. Therefore, they concluded that “practitioners can engage in a ratio that is personally comfortable and achieve the same BRS benefit.

For us, the take-home message is that slow breathing at a rate of 6 breaths/min improves cardiovascular and autonomic function. The best way to begin is to choose a ratio that is comfortable for you.

I suggest that you start with a 4 second inhale and a 6 second exhale and see how it feels. Begin with a five-minute session first thing in the morning and build up from there to reach three 5-minute sessions a day.

In good breath,
Nick

Can Breathing Improve Insulin Sensitivity? (+ 35 hours & 291 miles)

 
Learn_Well_vs_Do_Well.png
 
 

On Valentine’s Day, the CDC published a report documenting trends in diabetes incidence from 2002-2015. The take-home message: Rates of diabetes, both type-1 and type-2, are increasing in people less than 20 years old, especially in racial and ethnic minority populations.

Results like this make no-cost interventions more important than ever. (I will not get into the cost of diabetes here. But, I’m fortunate to have a job with great benefits, and I still feel the cost of diabetes daily.)

Which brings me to this week’s paper. It is a follow-on to the one I shared last week, which showed that relaxation breathing lowers blood sugar spikes.

Here, the same author published a review paper on breathing, glycemic response, and insulin sensitivity:

Review: Can yoga breathing exercises improve glycemic response and insulin sensitivity?

(Click Here to Read Full Summary)

Overall, this review concluded that slow breathing exercises can improve glycemic control and increase insulin sensitivity.

The glucose-lowering effect of slow breathing is likely due to reduced sympathetic activity and, subsequently, reduced glucose production by the liver.  That is, slow breathing reduces your body’s internal production of glucose.

The improved insulin sensitivity is likely related to reduced sympathetic output, but could also be due to improved tissue oxygenation.

These breathing techniques are so simple, yet they could be life-changing to diabetics.

If you feel inspired, please share the CDC study and this paper (or my summary of it) with someone you know with diabetes or pre-diabetes.

It’s a small, no-cost step in the right direction toward improving the lives of diabetics.

In good breath,
Nick

 

 

P.S. 100 Mile Ruck Thank You!

Thank you all for the support during the 100-mile ruck! It was the hardest thing I’ve ever done, but I finished.

Overall, it took me 35 h 45 min to finish and I took approximately 225,000 steps to cover the 100 miles.

Including those who walked with me, we put in a combined 291 miles for chronic disease and raised ~$2K for HHPF! Simply amazing! THANK YOU!

 

Yoga breathing significantly reduces PTSD in veterans

Yoga-Breathing-PTSD.png

For those of you who celebrate, I hope you had a Happy Thanksgiving!

I ate enough to almost start mouth breathing…


Before we get into this week’s research, I don’t want you to get the impression that breathing will cure PTSD. This study examined using breathing as complementary therapy, one that could be integrated as part of a complete treatment plan for PTSD. And they found encouraging results.

(Read the Full Summary of the Study Here)

The researchers studied 25 male Vietnam veterans from Australia. They were guided through a 5-day yoga program that consisted of breathing, mobility, asanas, and group therapy. Thus, there were several components to the study beyond breathing.

After the extensive 5-day training, the participants went once a week for 1 month, then once a month for 5 more months. In between sessions, they were encouraged to practice yoga breathing for 30 minutes every day. The study lasted a total of 6 months.

The researchers examined how the program affected the patients’ CAPS (Clinician Administered PTSD Scale) score, a 30-question interview that assesses PTSD severity. Scores range from 0 to 88, with higher values indicating more severe PTSD symptoms.

The average CAPS score at the beginning of the study was 56.3.  At week 6, the average score had significantly fallen to 42.1.  Finally, at the end of the 6 months, the average score had dropped to 26.2.

That’s pretty amazing. And this was with no changes to the participants medication.

Because yoga breathing is simple and has essentially no negative side effects, it could potentially be incorporated into the military health care system and be a valuable complementary therapy for PTSD.

Until that happens, let’s hope more scientific studies are conducted to assess the effectiveness of breathing programs for PTSD and to provide practical guidelines for using it as a complementary therapy.

In good breath,
Nick
