For a bargain, this wristband tracks your heart rate and displays it on a large, easy-to-read screen. It syncs additional information like steps walked, distance traveled, and estimated calories burned to the accompanying app. The watch is also waterproof, so you can even track your heart rate in the shower. The 10 Top Pedometers for Tracking Your Steps and More Best for Sleep: Fitbit Alta HR 4.1 Buy on Amazon Monitoring your heart rate while you sleep is just as important as monitoring it during activity—your resting heart rate can tell you if you’re at risk for certain metabolic or cardiac issues.

The Fitbit Alta HR tracks your heart rate while you sleep, giving you greater insight into your heart health. Many smartwatches offer sleep tracking, but Fitbit’s Alta slim design makes it more comfortable to wear when you’re dozing off.

If you discover you’re struggling at night, you can use behavioral methods to improve your sleep and avoid troubling symptoms of sleep deprivation during your day.
