A study shows that Apple’s smartwatch can accurately predict stress levels.

The University of Waterloo in Canada recently published a report showing how the Apple Watch can anticipate stress levels via the ECG sensor. Researchers found a close relationship between the ECG readings, specifically the slowing and speeding up capacity of the heart in accordance with the individual’s stress levels.

Machine learning was used to develop an algorithm and a prediction model. After testing, they found the model to have a “high degree of precision” and concluded it had “promising potential” for stress prediction. Researchers also believe that added health data, such as activity and sleep, could be integrated for greater accuracy.

Waterloo researchers said the Apple Watch could help mental health professionals with breathing exercises to try and change the wearer’s mental health status. The study is published on the official Pubmed.gov website.
