A study shows that the Apple Watch can actively detect stress, indicating a promising future for such features.
Stress is part of our daily lives; it’s how the mind and body react to external conditions, allowing us to operate. But stress also hurts us, whether it impacts the body or mind. Researchers from the, Canada, set out to see whether the Apple Watch can detect and track stress levels. And it turns out that Apple’s wearable can accurately predict stress levels.
The scientists collected data for two weeks from each volunteer and then developed machine learning algorithms to interpret the data. The researchers used the ECG to extract heart rate variability values, a parameter that can quantify stress.that the Apple Watch can be a predictor of stress, especially when it comes to detecting the absence of it:
The researchers say this is “the first study to use Apple Watch ECG data to predict the stress levels of individuals.”“The results are currently in the low-end of state-of-the-art,” and more research is required to improve the findings. A larger, more diverse sample of volunteers could further refine the results.
Put differently, Apple might be in a better place to build stress-tracking features into the Apple Watch. The company might be already working on such features, but that’s speculation.
