During all hours of the day, Fitbit wristbands monitor people’s steps, heart rate, sleep, calories burned, and more. This continuous tracking has made them useful not only for fitness fanatics, but also potentially for scientists who want a constant and close-up view of people’s health.
Today, Fitbit revealed just how often scientists have consulted activity-trackers in their research. Over the last four years, researchers have published more than 200 studies based on more than 2 billion minutes of Fitbit data. (Those numbers are according to both Fitbit and Fitabase, a platform that collected the devices’ data on behalf of scientists.)
