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.
"With wearable technology, learning more about yourself has not only become high-tech but also real-time. From devices and apps that help you track heart rate and food consumption details to gadgets that monitor your mood and even surrounding air, the "quantified self" is a reality for the everyday person. The result? You can learn about your own health with your own self-tracking devices and go a step further by using the devices to measure the success of self-improvement attempts."
