At this point, it’s pretty much common knowledge that a good night’s sleep is vital to your health. The much harder question to answer: How much sleep do you personally need each night? While adults generally need seven to nine hours a night (especially if they're training hard in the gym), time in bed doesn't always translate to quality sleep, and it's hard to know just by judging how groggy you feel when that alarm starts honking into your brain.
To solve this problem, various companies have tried cramming sleep tracking features into their all-around fitness trackers. But while an added sleep tracker on your Fitbit or Garmin is undoubtedly helpful, the added software can often lead to wildly inaccurate results. Worse yet, those inaccurate results can often send people spiraling into a cycle of stress over sleepless nights, which then means poorer sleep.
So if you're serious about tracking your sleep, you owe it to yourself to try a dedicated sleep tracker. We’ve rounded up five of the best devices to help you wake up in the morning, ranging from simple pillow clips to full-scale sleep systems with built-in alarm clocks—all designed to help you better understand your sleep cycle and get the most out of your nightly shuteye.
