Fitness trackers are great tools for helping you hit your health goals. They remind you to move throughout the day, keep track of changes in your heart rate, keep you accountable around your step count and, for better or for worse, let you know when you've had a rough night sleep.
Although perfect sleep every night just isn't viable, if you're consistently waking up to poor sleep metrics on your sleep tracker and, crucially, you also feel groggy or under-rested, it could be time to think about brushing up on your sleep habits.
