I went to sleep wearing my Apple Watch one night and awoke to a few hundred irregular heartbeat notifications.
They weren’t legit. The watch just can’t get a good heart rate reading if it’s not situated perfectly on your wrist, and while sleeping it was pushed one way or another often enough to be useless.
