Study: Smartwatch Stress Tracking Data May Be Inaccurate

Smartwatches that track your stress might not be very accurate.

A new study looked at how well smartwatches measured stress in young adults compared to how stressed they said they felt.

The study used smartwatches to track things like heart rate, which can go up for many reasons, not just stress.

The study found that the watch's stress readings often didn't match how people actually felt.

Sometimes, the watches even showed the opposite of what people were feeling.

Although the stress data wasn't accurate, the sleep data was a little bit better.

Researchers suggest the sleep data could be useful in the future to help detect when someone might be feeling down and needs help.
