Fitbit devices are well-known for their activity tracking capabilities, but they can also monitor your sleep. The Fitbit Versa 2, for example, is considered one of the best wrist-based sleep trackers on the market. It uses a combination of motion and heart rate data to show your time spent in various sleep stages, such as light, deep, and REM sleep. Fitbit devices automatically detect when you're asleep and provide a detailed breakdown of your sleep patterns, allowing you to assess if you're getting a healthy amount of sleep and make improvements where necessary.

What You'll Learn
Wear your Fitbit to bed
To track your sleep with your Fitbit device, you must wear it to bed. It is recommended that you wear your Fitbit in a snug wristband during sleep. Do not wear your device in a clip or pendant accessory. Fitbit devices automatically detect your sleep when you wear your device to bed. They do this by measuring when your body is completely at rest and you have not moved for about an hour. Additional data, such as the length of time when your movements indicate sleep behaviour (like rolling over), help confirm your sleep status.
If your Fitbit device tracks heart rate, it can combine heart rate and movement data to develop a more accurate picture of your sleep cycle. Fitbit devices that track heart rate (except Charge HR and Surge) also track sleep stages. While you sleep, your device tracks the beat-to-beat changes in your heart rate, known as heart rate variability (HRV), which fluctuate as you transition between light sleep, deep sleep, and REM sleep stages.
If you have a Fitbit Premium subscription, you can turn on the snore and noise detection feature to allow the microphone on your Fitbit Sense or Fitbit Versa 3 to track noise, including snoring from you or someone next to you. When you wake up, you'll find a summary of your nightly results in a report. To be eligible for a sleep profile, you must wear your Fitbit during sleep for at least 14 days during the previous month (these do not have to be consecutive days).
To help you maintain a consistent sleep schedule, you can set a bedtime reminder in the Fitbit app. When it's time to wind down for bed, you will receive a notification on your phone. On certain Fitbit devices, you can also find a bedtime reminder on your device.

Understand your sleep score
Your sleep score on your Fitbit device is a feature that helps you understand your sleep each night so you can monitor trends in your sleep patterns. The score is based on your heart rate, the time you spend awake or restless, and your sleep stages. The sleep stages refer to the cycles of sleep that your body typically goes through during a night of sleep. These include light sleep, deep sleep, and REM sleep. Light sleep is the entry point into sleep as your body unwinds and slows down. Deep sleep typically occurs in the first few hours of sleep and is harder to be awakened from since your body becomes less responsive to outside stimuli. REM sleep is associated with vivid dreams and the periods of REM sleep tend to be longer towards the end of the night.
To get your sleep score, you need to wear your Fitbit device to bed. Your Fitbit device will automatically detect your sleep when your body is completely at rest and you haven't moved for about an hour. The next morning, you need to sync your device to review your sleep data, including your sleep score. You can check your sleep score in the Fitbit app by tapping the Sleep duration tile from the Today tab.
You can also purchase a Fitbit Premium subscription to access additional insights into your sleep data, such as a detailed analysis of your sleeping heart rate and a breakdown of your sleep score. The subscription also provides a monthly sleep profile that includes 10 monthly metrics and a sleep animal characterisation of your long-term sleep behaviours. To be eligible for the sleep profile, you must wear your Fitbit during sleep for at least 14 days in the previous month and your sleep logs must include sleep stages data.

Get a sleep profile
To get a sleep profile on your Fitbit Versa, you need to meet certain requirements. Firstly, you must have a Fitbit Premium subscription. This subscription gives you access to more sleep data and insights, such as snore detection, and a more detailed breakdown of your sleep score.
Secondly, you need to use a compatible device, which includes the Fitbit Versa 2, 3, and 4. The Versa 2 is considered one of the best wrist-based sleep trackers on the market, using a combination of motion and heart rate data to show your time spent in various sleep stages.
Thirdly, you must wear your Fitbit during sleep for at least 14 days during the previous month. These days do not have to be consecutive, and the more sleep you log, the more accurately your sleep profile will reflect your patterns. Your sleep logs must include sleep stages data, which can be found by tapping the sleep entry on the list on the main screen of the Fitbit app.
Finally, ensure that your Fitbit has recently synced. You can check your sleep profile on the first of the month in the Fitbit app or on your Fitbit device.

Check your sleep pattern
To check your sleep pattern, you must wear your Fitbit device during sleep. Fitbit devices automatically detect your sleep when you wear your device to bed. It is recommended that you wear your device in a snug wristband during sleep. Do not wear your device in a clip or pendant accessory. Your device records that you're asleep when your body is completely at rest and you haven't moved for about an hour.
Fitbit devices that track heart rate also track sleep stages. Sleep stages are traditionally measured in a lab using an electroencephalogram to detect brain activity, along with other systems to monitor eye and muscle activity. Your Fitbit device can estimate your sleep stages in a more comfortable and convenient way. It estimates your sleep stages by using your movement and heart-rate patterns. While you sleep, your device tracks the beat-to-beat changes in your heart rate, known as heart rate variability (HRV), which fluctuate as you transition between light sleep, deep sleep, and REM sleep stages. When you sync your device in the morning, it uses your movement and heart rate patterns to estimate your sleep cycles from the previous night.
After you wake up in the morning, you can review the information Fitbit has recorded about your sleep. Start the Fitbit app on your phone and wait for it to sync. You can see your overall sleep time on the Today page. This is the time Fitbit believes you were asleep the previous evening, not including any time you were restless or woke up during the night. The Fitbit Today page displays your total sleep time for the previous evening. Tap the sleep entry to go to the detailed Sleep page. At the top of the page, you'll see a graph that shows how you slept for the last week.
Swiping the graph will allow you to see three tabs: how long you slept each night, your sleep schedule (the hours you were asleep), and a summary of your sleep stages. The top of the Sleep page shows how many hours you slept each night. You can swipe for different views of the week. You can tap any day below the graph to see details about your sleep cycle for that day. You can use the information to look for trends, like if you consistently don't get enough sleep, or sleep restlessly and wake up often during a night's sleep.
