Google's newest Pixel Watch feature can monitor your blood pressure and insulin resistance

At the launch of the Pixel Watch 5, Google announced Health Guardian, a new suite of tools to keep an eye on your health. Google says its new platform will be able to see trends on your blood pressure, breathing and, most interestingly of all, insulin resistance. If it has been able to achieve the latter, then the consequences could be staggering. Cuffless blood pressure monitoring is increasingly common in high-end wearables, but with a lot of caveats around accuracy. Samsung's Galaxy Watch feature, for instance, asks that users regularly calibrate their watch against a traditional blood pressure cuff.
