A new pilot study has been published in the journal Frontiers in Digital Health , according to which the Apple Watch can recognize the stress level of its wearers with a new function. The stress detector uses electrocardiograms, so-called ECGs, and measures the heart rate of the electrical impulses. Based on continuous measurement with the help of machine learning, a tool for predicting stress could be developed in the future that makes it possible to react to changes in mental health at an early stage.
