Hi everyone!
I managed to not get infected with COVID-19 until 2 weeks ago. A runny nose and sore throat pushed me to do a self test, which immediately showed a positive result. Interestingly, I noticed my Apple Watch recorded a jump in my resting heart rate of 20 beats a full day before my symptoms appeared.
Could my Apple Watch have warned me in advance? Turns out that both Apple and Fitbit have run studies and found that their devices can indeed detect infections early on. Cool! Given enough data and good sensors, I’m convinced we’ll soon be able to detect even more. A bit like having “predictive maintenance” for our bodies.
Anyway, I’m all better now, and I hope you enjoy this edition of the newsletter.
Take care,
