If you’re still on the fence about just how useful a smartwatch can be, a group of researchers at Stanford University have some news for you. The scientists discovered that using algorithms to monitor a combination of vital signs gathered by the Basis B1 and Basis Peak can determine if you’re about to catch a cold, days before you actually get sick. Using stats like heart rate and skin temperature, researchers say the smartwatches can indicate the first signs of an impending illness.
