Track While You Sleep

What Information Does Fitbit Track While You Sleep

Fitbit offers an advanced sleep monitoring technology that also monitors the variations in your heart rate from beat to beat, or heart rate variability.

These alterations, in the opinion of Fitbit’s specialists, represent the various sleep cycles you are experiencing, such as REM, deep sleep, and light sleep stages. Your entire movement is taken into account by Fitbit as well. It notices the slower movement when you are sleeping and, eventually, will conclude that you are already sleeping.

When you wake up in the morning, Fitbit will provide you with a sleep score that takes the following factors into account.


Based on your heart rate variability, Fitbit will determine how long you spent in each stage of sleep. Generally speaking, getting REM or deep sleep will raise your score.


You’ll receive a higher score if you take longer periods of time to rest.


This evaluates how calm you were while you slept. Basically,  your score will rise if your heart rate slows while you move less.

When Does Your Fitbit Device Start Sleep Tracking

It varies on the settings you have chosen and the device version you are using.

Older Versions

Your Fitbit will track your sleep manually if you still use a Fitbit One or Fit Bit Zip. Simply press and hold the tracker’s button for a few seconds as you prepare to go to sleep.

You’ll notice that the other tracker symbols start blinking as soon as the stopwatch starts counting, it means you are in sleep mode.

To end the sleep recording in the morning, simply keep holding down the button for a short period of time. Once sleep mode is turned off, the icons will stop flashing.

Newer Versions

If you have a more recent model, such as one from the Alta, Blaze, Charge, Flex, Inspire, Surge, Ionic, or Versa series, your device has automatic sleep tracking.

In the event that you feel the automatic readings are not accurate enough, you can always shift to the manual settings.

Using manual mode results in an extra statistic, the time it takes for you to fall asleep.

Other than that, the specifications of automated and manual mode are not significantly different.

If your Fitbit is working properly, it will start tracking your sleep as soon as it detects your heart rate variability and your movement. Your Fitbit device will conclude you are in at least light sleep once your heart rate slows down. Fitbit will assume you are sleeping if it notices a significant slowdown in your movement.
