Can Apple Watch predict stress? Study claims the device can do it accurately
According to a report by 9to5Mac, a study has concluded that the Watch’s ECG sensor data can be used to develop a robust and accurate stress prediction tool. The study was conducted by the researchers from the Canada-based University of Waterloo.
Apple introduced the electrical heart rate sensor along with the ECG app with Apple Watch Series 4. The feature can record your heartbeat and rhythm, and then check the recording for atrial fibrillation (AFib), a form of irregular rhythm. At present, the feature is available on Series 5, Series 6, Series 7, Series 8 or Ultra along with the Apple Watch Series 4.
