Sleep Gadgets So Weird They Just Might Work
How it works: The simple rubber bracelet is actually a sophisticated health-monitoring device. It tracks large and small movements to show you when you're awake, dozing lightly or knocked out in deep sleep. With the accompanying app, you can also track how much (or how little) you exercise as well as what you eat and drink.
Why we'd like to try it: We may like to think that we get 7 to 8 hours of quality rest every night, but the Up will let us know that the hour of Facebooking didn't count toward our quota. And research shows that when we track our habits, we're more likely to want to do more-healthful things.
