Fitbits and other fitness trackers are particularly suitable for medical studies on COVID-19 because they track respiratory organs such as breathing and heart rate (via Medscape), among other things. Scientists can then use these vital signs compared to those who haven’t had COVID-19, along with those people’s pre-contraction vital signs to learn how the virus will affect people over the long term – and how long it will affect you .
Medscape noted that recent studies show that of all people tested who tested positive for COVID-19 took longer to return to normal breathing, sleep, and activity than their counterparts who did not contract the virus . In addition, according to people, those who had COVID-19 took an average of 79 days to return to normal heart rate levels, while 14% had elevated heart rates for more than four and a half months after contracting the virus.
In short, “There was a much greater change in resting heart rate in people with COVID compared to other viral infections,” said epidemiologist Dr. Jennifer Radin (via The New York Times). “Many people who get COVID end up developing autonomic dysfunction and some sort of persistent inflammation, and this can affect their body’s ability to regulate their heart rate,” she continued.
Ultimately, fitness trackers prove to be more useful than just counting your daily steps. Now they are scientific measuring instruments and can help you monitor your own vital signs at home.
