A look at promising treatments for COVID-19
Fitness trackers turned COVID trackers
Mount Sinai's "Warrior Watch Study" is ongoing. Other researchers have also found benefits in so-called wearables like the Apple Watch, Fitbit and other fitness trackers.
Nature Biomedical Engineering found that smartwatch data can help detect COVID-19 before it's diagnosed through a test. The researchers from Stanford University looked at factors including heart rate, number of daily steps or time asleep.
Retrospectively, they found for example that "63% of the COVID-19 cases could have been detected before symptom onset in real-time via a two-tiered warning system based on the occurrence of extreme elevations in resting heart rate relative to the individual baseline," the authors state in their paper.
