The elegant-looking piece of wearable tech monitors everything from your heart rate and physical activity levels to body temperature and stress. It can even alert you if you are about to get sick. But it's the Oura's sleep-tracking abilities that are its main selling point. The ring not only tracks the amount of sleep you've had, but also how restful that sleep was by assessing sleep latency and efficiency as well as how much deep sleep and REM sleep you get each night.
