Wearable Technology Can Help Detect Illness Early

Millions of Americans now head out the door each day wearing devices that count their steps, check their heart rates, and help them stay fit in general. But with further research, these “wearables” could also play an important role in the early detection of serious medical conditions. In partnership with health-care professionals, people may well use the next generation of wearables to monitor vital signs, blood oxygen levels, and a wide variety of other measures of personal health, allowing them to see in real time when something isn’t normal and, if unusual enough, to have it checked out right away.
