Google rolling out blood pressure, insulin resistance on Pixel Watch

As previewed during last month’s Pixel Watch 5 launch, Google is now starting to roll out blood pressure trends, insulin resistance trends, and sleep breathing quality metrics.

Health Guardian is Google’s overarching brand for the Pixel Watch’s suite of “proactive health and safety tools.” It includes Breathing Emergency Detection, which is available in Europe on the Pixel Watch 4 and 5.

The blood pressure trends feature works by passively measuring your pulse and motion patterns over the course of a month. It’s intended to let you detect “persistent higher cardiovascular trends early.” This works without a cuff or manual calibration, and was trained using billions of minutes of raw heart and movement data. You need “at least 5 consecutive days in a week” of data.
