Using Freestyle Libre To See How Stress Effects My Blood Glucose Levels

Justin Lawler, the organizer of Quantified Self Dublin, has been doing some interesting self-studies about how various changes in his life affect his blood glucose levels. Blood glucose is typically tracked as part of diabetes care, and there are some excellent emerging tools for convenient tracking without doing finger stick tests. (Although these systems are not yet accessible everywhere without a doctor’s prescription, we’ve seen them more and more often in Quantified Self projects over the last few years.)

In a recent post, Justin outlined some of his latest projects and discoveries. Among the most interesting findings was the clear relation between psychological stress and blood glucose spikes. For instance, this chart that covers the time he was giving a talk at last year’s Quantified Self conference in Amsterdam.

“My worst data point by far,” Justin writes, is when I’ve been most stressed—giving a talk at the Quantified Self Europe Conference.” You can see his graph below, which shows his blood glucose spanning the time of his talk.
