NASA will provide 1,000 of its employees, including 150 astronauts, with Fitbit devices in a pilot program designed to see if they can help supplement efforts to keep these mission-critical personnel healthy ahead of key space missions. The program will see NASA employees outfitted with a wearable and provided access to a daily check-in app they can use to log potential symptoms, as well as their body temperature and other key health metrics, which could potentially help spot developing cases.
NASA has already been taking measures to isolate astronauts and to limit or prevent the spread of COVID-19 across its facilities, which are located across the U.S. It has of course followed local guidelines and requirements regarding COVID-19 protections, but it also introduced its own level-based system last year and implemented remote work protocols for many employees wherever possible. On the astronaut side, it has also beefed up existing isolation and sequestration procedures that are already quite strict in order to guarantee that its spacefarers don't get sick before they're set to make a trip to the International Space Station.
The new Fitbit program is designed to supplement those existing measures, providing tracked health metrics including resting heart rate and heart rate variability, as well as respiratory rate, changes in all of which have been linked to COVID-19. Those stats, along with the self-reported metrics logged by users themselves, including any reports of potential symptoms, will be used by the app to provide individuals in the program with guidance about whether they should go into work, or stay home and take additional measures to find out if they have COVID-19.
Fitbit is already engaged in studies to determine whether its wearable devices and the metrics they log can be useful in providing early COVID-19 detection. Regardless of those results, self-reporting as well as the baseline health metrics that the app logs from its devices are already likely to be handy in providing a supplement to existing self-assessment measures regarding the level of risk you pose to others if you're feeling off, which is the primary purpose of this program with NASA.
