Researchers are looking at smartwatches to see how they can help detect COVID-19.
Mount Sinai Hospital is trying to see what information watches could give about diseases that cause inflammation.
COVID-19 also causes inflammation.
Researchers say heart rate variability, the time difference between each heartbeat, gives some information about inflammation and smartwatches already collect that information.
"Interestingly from that, you could derive a sense of the activity of someone's nervous system. Their autonomic nervous system which is the part of your nervous system that controls your bodily functions, kind of without you even thinking about it," said Dr. Rob Hirten, assistant professor of medicine for Mount Sinai Hospital.
Even though researchers are still studying this smartwatch technology, they're hoping it will eventually be used to help mitigate and control the spread of COVID-19.
