Studies have shown that smartwatches such as the Apple Watch and FitBit may be able to detect positives a few days before the onset of symptoms of the new coronavirus infection.

According to researchers at Mount Sinai School of Medicine, Apple Watch can predict a new corona infection a few days before being tested for symptoms. The index is “Heart Rate Variability” (HRV / periodic fluctuation of heart rate interval), which is said to be a good measure of how the immune system works.

Because, “I know that heart rate variability changes as inflammation occurs in the body.” The new corona causes incredible inflammation, which is a good indicator that you can predict that you are infected without your knowledge.

People infected with the new corona have been shown to have lower heart rate variability than those with negative heart rate variability, that is, less hourly heart rate variability. High heart rate variability does not mean that your heart rate is rising, but that your nervous system is active, adaptable, and resilient to stress, and conversely, when it is low, they are lost. It seems that it is being damaged.

The study is based on the results of a follow-up of nearly 300 healthcare workers at the university wearing Apple Watch from April 29th to September 29th. Apple hasn’t participated in or funded the study, but was mentioned by CEO Tim Cook at the “Time Flies” (new Apple Watch announcement) event last September.

Another study from Stanford University has shown the results of using fitness trackers from multiple manufacturers such as Apple Watch, FitBit, and Garmin. According to the report, 81% of the participants who were positive for the new corona had experienced a change in resting heart rate 9 and a half days before the onset.

Professor Michael Snyder, who conducted the study, points out that detection by smartwatches may help to make up for some of the shortcomings of the new corona test. That is, “The problem is that people can’t always test, but these devices can measure 24 hours a day, 365 days a year. Smartwatches return data instantly in real time, and if you’re lucky, the test results will be available in a few days. It will come back. ”

The Stanford University team has also developed a system that warns you if your heart rate is rising for a long time. These studies may lead to the infection being unknowingly refraining from going out or meeting other people, and thus converging the infection, as the majority of infections are prevalent in asymptomatic people. not.
