Meditation Reduces Blood Glucose

Stress raises blood glucose significantly

Dawn effect — screen capture from the author’s stressful day

I have metabolic syndrome. My glucose runs too high, and I am insulin-resistant. If I eat a small amount of carbohydrates or sugar, my blood glucose spikes far more than it would for someone with a normal glucose response. I wear a Continuous Glucose Monitor (CGM) to help me figure out my diet and keep my blood glucose under control. I wrote about biohacking with a CGM sensor here:

The following iPhone screenshots were taken from the Nurisense App that I use in conjunction with my CGM monitor. Typically, my Dawn effect would push my glucose number up to 160 for a few hours between 5 AM and 9 AM before they came back down within a normal range.

I was having a good run, I was trying out a few bio-hacks and it helped keep my daily blood glucose under the recommended 140 mg/dL for most of the day.

However, on Nov. 21, see photo above, I was scheduled for a dental procedure, something I was not looking forward to, I noticed my dawn effect that morning went out of normal range, in spite of my hacks. The next day it went back to basically under control again. Because I wear a CGM, it became a simple matter to scroll back a day to observe the dawn effect the day before and the day after my dental appointment.

While I had a nutritionist tell me stress affects blood glucose response, it’s one thing being told and another observing it in my own body. The observation has a far greater impact.

What do to with this information?


It stands to reason anything that reduces stress should have a positive impact on my glucose. I jumped on Pubmed and searched for information on meditation and blood glucose. The search results were positive. A clinical study was performed in 2020. What I found…
