Wear your Fitbit to bed
To turn on sleep tracking for your Fitbit Charge HR, you must wear your device to bed. This is because the Fitbit Charge HR automatically starts logging your sleep once it recognises that your body has entered sleep mode.
When you wear your Fitbit to bed, it will monitor your slumber by recording the amount of time you are asleep, as well as the quality of your sleep. It does this by using metrics such as physical movement, pulse rate, and breathing to infer which sleep stage you are in. If you don't move for about an hour, your Fitbit will assume you are asleep. It will also track the beat-to-beat changes in your heart rate, known as heart rate variability (HRV), which fluctuates as you transition between light sleep, deep sleep, and REM sleep stages.
To get the most accurate readings, wear your Fitbit moderately snugly and higher on your wrist (toward your elbow). If you want to track your sleep using the Fitbit app, make sure your device is charged to at least 40% before going to bed. If your Fitbit runs out of battery during the night, your sleep data will be missing some information.
In addition to tracking your sleep, you can also set a silent alarm on your Fitbit. To do this, go to the main screen of your device and swipe left until you see the alarm clock icon. Tap the time to set your alarm, then toggle the slider to turn it on. When the alarm goes off, it will vibrate to wake you up.

Check your sleep data
To check your sleep data on the Fitbit Charge HR, you must first sync your device each morning. This will allow you to review your sleep data, such as your sleep score and the number of hours you slept. You can check this information on your Fitbit device or in the Fitbit app.
In the Fitbit app, you can view your sleep data by opening the Today tab and tapping the Sleep duration tile. Here, you will see the total sleep duration from the previous night, as well as your Sleep Score. You can also swipe left on the Sleep Tile to view more detailed data from the previous night, as well as your sleep history for the week.
If you tap on the sleep card in the app, you can view your sleep stats for longer periods, such as several months or even a year. You can toggle between "Hours Slept" and "Sleep Schedule" using the buttons under the charts.
If your Fitbit Charge HR does not have a heart rate monitor, you can still check your sleep pattern in the Fitbit app, which will show your time spent awake, restless, and asleep.
If you have a Fitbit Premium subscription and a compatible device, you can also access a Sleep Profile, which provides a more detailed breakdown of your sleep once a month.
