better blood sugars

More Breathing in Less Time

 

Greetings,

This week’s 411 is brought to you by espresso, curiosity, my appreciation for your readership, and espresso. Enjoy!

 
 
 
 

4 THOUGHTS

1. Use Breathing Instead of Thinking

"Social psychologists now know that the truth lies in the opposite direction. People need to change their actions and their minds will follow." – Sean D Young, Stick With It

Experts tell us it’s hard to think our way out of thinking. We need to act and let the mind follow. I believe this is what makes breathing so powerful. It gives you an action you can perform anytime to trick your mind into following.

If you’re anxious, you can breathe slowly, which will calm your nervous system and lead to calmer thoughts. If you’re tired, you can breathe rapidly and stimulate your nervous system, increasing your heart rate and alertness.

There are many ways to use actions to control your emotions and thoughts. But breathing is free and easy. Stop thinking, begin breathing.

2. Post-Meal Breathing for Better Blood Sugars & Digestion

Relaxing breathing methods have been shown to reduce blood sugar spikes associated with meals and glucose tolerance tests. In Breath (pg 43), James Nestor also tells us that right nostril breathing heats up the body and aids in digestion. Together, it seems like a post-meal breathing practice might be a good idea.

I have been testing this in a simple and practical way. Specifically, I’ve been spending ~3 to 5 minutes performing either alternate nostril or diaphragmatic breathing (or their combination) after lunch.

The results have been quite noticeable. My sugars are much better (and even get low sometimes) in the hour following the meal. And these short minutes are especially helpful midday to focus my mind and get me back to work quickly.

Science + Practicality = Better Living

Even if you don’t have diabetes, adding this tiny habit after eating might help with digestion and improve energy levels. Not bad for just a few minutes.

3. More Breathing in Less Time

Brian Johnson is my favorite teacher. Long-time readers are probably sick of me talking about him : ) His motto: More wisdom in less time. In that spirit, here are a few excellent summaries Brian has made of some of the best breathing books:

Enjoy!

Thanks to new 411 reader W.G. for inspiring this thought.

4. The Best Advice You Can Give Someone Interested in Breathing

"Start now. Optimize later. Imperfect starts can always be improved." - James Clear

The Oxygen Advantage, Wim Hof, The Art of Breath, Buteyko, Breatheology, SKY, ujjayi, and on and on. They are all phenomenal for different reasons.

But the most important thing is to choose one and start—experience for yourself how simple and powerful these practices are. You can optimize later.

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!

 

Relaxation Breathing Reduces Blood Sugar Spikes

This week, I am sharing one of those amazing papers that I read and underline the whole thing. Despite having a small sample size, it hints at the incredible benefits of breathing for optimal blood sugars.

Relaxation Breathing Improves Human Glycemic Response

(Click Here to Read the Full Summary)

The study participants were randomized into a control group (n=13) and a relaxation breathing group (n=13). The relaxation breathing (RB) protocol used a constant inhale with a progressively longer exhale:

  • Inhale 2 sec, exhale 1 sec.

  • Inhale 2 sec, exhale 2 sec.

  • Inhale 2 sec, exhale 3 sec.

  • …

  • Inhale 2 sec, exhale 10 sec.

The participants performed this exercise once every 10 minutes for 30 minutes prior to an oral glucose tolerance test. Then, they did it every 10 minutes for 90 minutes after the test. Overall, they did the RB technique 3 times before and 9 times after the test. The control group simply took the glucose tolerance test.

The results showed that the RB group had a significantly lower blood sugar (~37 mg/dL lower) thirty minutes after the glucose tolerance test.  After an hour, the two groups were approximately the same. Thus, relaxation breathing reduced the blood sugar spike associated with the glucose tolerance test.

Although the exact mechanisms are not clear, it seems likely that activation of the parasympathetic nervous system improved the insulin response of the RB group, and might have also improved insulin sensitivity.

This study provides another scientifically-validated breathing technique we can use to improve our blood sugars. After reading this paper, I started using it quite often.  I’ve found it’s nice to do while lying in bed before sleep.  I also find it helpful at the beginning of a breathing/meditation session just to calm everything down. 

And, with how simple it is, you do not need a watch or app. You can simply count in your head. It only takes ~75 seconds to complete one cycle and it will leave you feeling calm and relaxed (and potentially lower your blood sugar).

Give it a try before your next meditation or breathing session as a way to prepare you for relaxation.

In good breath,
Nick

P.S. I am finalizing this post on Friday, Feb. 28, and do not plan to look at it again before Monday (I am assuming my body/mind will not be in any capacity to do so). Hopefully I made through the 100 miles with no major issues. If you still want to donate, it’s not too late. HHPF is always accepting donations to further their mission. Thank you for your support!

 

Exercise and Hypoxia Increase Insulin Sensitivity (& 100 Mile Ruck Website)

 
Stand_vs_Going.png
 
 

There are many paradoxes in breathing. For example, breathing less air delivers more oxygen to your cells.

Here is another one. Many diabetic complications (for example, insulin resistance) are rooted in tissue hypoxia. Yet, the deliberate practice of intermittent hypoxia (IH) can improve insulin sensitivity, as shown by the study I’m sharing this week.

Acute hypoxia and exercise improve insulin sensitivity (Si2*) in individuals with type 2 diabetes

(Read the Full Summary)

This research examined four different protocols:

  1. Rest at normal O2 levels for 60 min

  2. Rest in hypoxia for 60 min

  3. Exercise with normal O2 for 60 min

  4. Exercise in hypoxia for 60 min

All participants were type 2 diabetics. Oxygen levels for the hypoxic group were maintained at ~14.6%, and the results showed that the participants’ SpO2 never fell below 88% (well within the therapeutic range).

Here were the main findings:

  • Hypoxic rest increased insulin sensitivity more than rest at normal O2 levels

  • Hypoxic exercise improved insulin sensitivity greater than exercise in normal O2 levels

Together, these results imply that exercise and hypoxia can be added together to improve insulin sensitivity.

However, before jumping in, we must remember that hypoxia does induce stress, and stress hormones increase the body’s production of glucose. Thus, the increased insulin sensitivity could just be the body’s preemptive response to the stress: It knows more sugar is coming, so it primes itself to use it.

We should keep this in mind as we practice intermittent hypoxia: It’s important to find our Goldilocks zone, where we’re experiencing hypoxia, but not inducing too much stress. I recommend starting slowly with walking breath holds. You get the benefits of exercise and hypoxia in a safe, easy-to-perform way.

Try adding 3-5 walking breath holds to your morning routine. They don’t have to be intense, just enough to feel it. And, make sure you can recover normal breathing within 3 breaths after the hold…this ensures you do not push too hard.

Give it a shot, and remember, consistency over intensity.

In good breath,
Nick

I'm Rucking 100 Miles + Diaphragmatic Breathing Improves HbA1c

 
One_Step_At_a_Time.png
 
 

Announcement:
I’m Rucking 100 Miles for Chronic Disease

On Leap Day, February 29th, I’m going to ruck 100 miles to raise money for the Health and Human Performance Foundation (HHPF).

If you’ve been following me for a little while, you know I’m a huge fan of their mission. They are an amazing nonprofit raising awareness around the benefits of breathing for chronic disease, stress, and anxiety.

Given the impacts breathing has had on my life, I wanted support their cause. What better way than a ridiculously long walk?

I am wearing a weighted rucksack to symbolize the extra weight we carry around as those living with chronic disease. Yet, despite that weight, we can still accomplish anything. In fact, that weight makes us stronger. I wholeheartedly believe diabetes has made stronger.

We are setting up a donations page on HHPF, which I’ll be sending out separately. If you feel so inspired, donate to help support their great mission. And please support me by telling others, sharing our posts on Instagram, and spreading the word about HHPF.

Thank you in advance for your support!

Now, on to the science.

 
 

Last week, we learned that diaphragmatic breathing improved HRV and lowered HbA1c. This week’s research reveals that it also improves antioxidant status in type 2 diabetics.

Diaphragmatic Breathing Exercise as a Therapeutic Intervention for Control of Oxidative Stress in Type 2 Diabetes Mellitus

(Read the Full Summary)

This is one of the early papers I posted to The Breathing Diabetic. I often go back through important papers to reinforce the ideas and see if I notice new things I missed before.

This one did not disappoint. Just re-reading all of my notes on this one energized me (image below). I’m fascinated with breathing, but sometimes I need a paper like this to remind me how important it is to get this research out.

The Breathing Protocol

One hundred and twenty three type-2 diabetics participated in this study. Sixty were placed in the diaphragmatic breathing group, and 63 served as controls.

The participants were instructed to lie down, place one hand on their chest, one hand on their belly, and breathe deeply and slowly, only allowing the hand on their belly to move.

This protocol is almost identical to the Oxygen Advantage “Breathe Light Advanced” exercise.

They were asked to perform this procedure for 15-20 minutes, twice a day, for 3 months.

Breathing Improves Oxidative Stress and HbA1c

At the end of the 3 months, participants in the breathing group had significantly lowered their oxidative stress by increasing antioxidant levels.

Additionally, they decreased their HbA1c by 3%. Now, this isn’t 3% as in dropping from 9% down to 6% (like last week’s study). This was 3% of their original value. Not quite as significant, but still encouraging. And, remember the study from last week didn’t see major improvements in HbA1c until the 12 month follow-up.

In short, diaphragmatic breathing led to:

  • Decreased oxidative stress

  • Better blood sugars

In good breath,
Nick

P.S. Here’s the first page of my notes on this article. I was clearly excited the first time I read it too.
