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.

Humans aren't built for the cold, but have survived frigid temperatures in some amazing cases. Breakthroughs, discoveries, and DIY tips sent six days a week. Winter is not for the faint of heart. In New York City, skyscrapers turn Manhattan into a series of freezing wind tunnels. In Sapporo, Japan, the snowfall is almost 200 inches each winter. Even so, humans have developed plenty of clever ways to wait out the cold. But what would happen if instead of bundling up inside with a hot chocolate, you were left in the frigid cold--just how cold can humans get and recover?

In some remarkable cases, people have survived after their core temperature has plummeted into the 50s. The human body needs to maintain the same internal body temperature or else many vital systems fall apart. Breakthroughs, discoveries, and DIY tips sent every weekday. Whether you prefer sweltering summers or frigid winters, significant temperature changes mean only one thing to your body: bad news. Humans are homeotherms, meaning that our core body temperature stays roughly constant.
