The NBA is giving players the option to wear a device that tracks their health data when basketball games begin this July. The device - called an Oura Ring - can measure things like the body’s temperature and heart rate. The hope is that it could provide the league with early warning signs that someone may have contracted an illness like COVID-19. Bloomberg reporter Kristen V. Brown reports that the move is part of a larger conversation about whether or not wearable technology like a Fitbit or an Apple Watch can help fight the pandemic.
