Country vs. Country
“These are my favorite charts,” says Emir-Farinas. She plotted age-adjusted data from the 55 countries with the most Fitbit wearers.

Active Minutes per Day vs Average Resting Heart Rate by Country, FitBit data
The variation in heart rates is, to me, just crazy. Among people who get about 55 minutes of activity a day, the RHR is about 62 beats a minute in Costa Rica, but almost 70 in India! What could that mean?
“That means there’s other factors at play,” Emir-Farinas says. “It’s their nutrition, it’s their BMIs, it’s their practices, medication — and genetics, of course. That’s also a big part of it.”
In general, Europe beats the world here. “They have designed their cities so that there will be more physical activity. People have to walk more just do normal activities: going to the grocery store, going to work, they have to walk a little,” she says. (Check out Sweden, for example: almost 90 minutes of activity a day!)
They also drink a lot of wine in Europe. Just sayin’.
The scientists note that Qatar seems to be an outlier. Seventy percent of the Qatari population is obese — yet their RHR is an impressive 62. How could that be?
Emir-Farinas’s theory is that huge numbers of them are on blood-pressure and heart meds.
Congratulations to Italians, by the way, with an impressive 84 minutes a day of activity, and a nearly-dead 61 beats-a-minute RHR.
And as for Pakistan, with the worst activity level and a sky-high RHR — get with it, people!
