An Apple Watch without an EDA sensor can track stress accurately

The Apple Watch is the most well-known smartwatch on the market, but in terms of sensors, it trails Fitbit and Samsung. However, according to another review published in Wildernesses in Computerized Wellbeing (via MyHealthyApple), they may not be necessary.

In a pilot study with 33 mostly white female participants, specialists had the option of developing a pressure forecast device utilizing pulse changeability information from the ECG sensor on the Apple Watch Series 6 combined with AI strategies. A 30-second ECG examination gave them instant feedback on their anxiety feelings, with an exactness of 52% to 64%, as opposed to 60% to 80% for "best in class precision for stress recognition, in actuality, settings," according to the review.

Those are impressive results from a single ECG sensor. Because of the relationship between stress and skin conductance changes, those results would presumably be higher when using the new temperature sensor on the Apple Watch Series 8 and Apple's own stress algorithms.

Fitbit released its new Sense watch in 2020, which included a new continuous ElectroDermal Activity (EDA) sensor that tracked tiny electrical changes on your skin to help identify when users were stressed. It was hailed as a leap forward from the Apple Watch, which had only recently caught up with Fitbit's blood-oxygen sensor from five years ago..Clients should hold their palms over the screen for 2 minutes while using a dedicated EDA application to get a reading.
