Fitbit devices track sleep patterns by monitoring movement and heart rate
Fitbit devices are designed to track sleep patterns by monitoring movement and heart rate. The devices automatically detect sleep when the wearer hasn't moved for about an hour and their body is completely at rest. The Fitbit then records this as the wearer being asleep.
The device also tracks the length of time when the wearer's movements indicate sleep behaviour, such as rolling over. This additional data helps confirm the wearer's sleep status. While the wearer is asleep, the device tracks the beat-to-beat changes in their heart rate, known as heart rate variability (HRV). This fluctuates as the wearer transitions between light sleep, deep sleep, and REM sleep stages.
The Fitbit app provides a detailed sleep breakdown, available on the first of every month. The app includes a Sleep Duration tile, where users can view their sleep profile and check how close they are to getting next month's profile. The app also includes a Today tab, where users can tap the Sleep Duration tile to view their sleep timeline graph and press and hold to check the time spent in each sleep stage.
For a more detailed analysis of sleep patterns, users can subscribe to Fitbit Premium. This subscription service provides a Sleep Profile reading, which uses various sleep metrics to inform the user about trends in their sleep patterns and how they compare to other people of the same age and gender. The Premium service also includes the snore and noise detection feature, which allows the device to track noise and snoring throughout the night.

Fitbits can differentiate between light sleep, deep sleep, and REM sleep
Fitbit devices can differentiate between light sleep, deep sleep, and REM sleep. They do this by tracking the beat-to-beat changes in your heart rate, known as heart rate variability (HRV). This fluctuates as you transition between the different sleep stages throughout the night.
Fitbit's sleep researchers and the National Sleep Foundation describe the different sleep stages as follows:
Light Sleep
Light sleep serves as your entry point into sleep each night as your body unwinds and slows down. This stage typically begins within minutes of falling asleep. During the early part of light sleep, you may drift between being awake and asleep, remaining somewhat alert and easily awoken. Your breathing and heart rate usually decrease slightly during this stage. Light sleep promotes mental and physical recovery.
Deep Sleep
Deep sleep typically occurs in the first few hours of sleep. When you wake up feeling refreshed in the morning, you likely experienced solid periods of deep sleep the night before. During deep sleep, you become harder to be awakened since your body becomes less responsive to outside stimuli. Your breathing slows down, your muscles relax, and your heart rate usually becomes more regular. Deep sleep promotes physical recovery and supports aspects of memory and learning, as well as your immune system.
REM Sleep
The stage associated with vivid dreams, REM sleep periods are typically longer as the night goes on. REM sleep usually occurs after the initial stage of deep sleep and is longer during the sleep cycles in the second half of the night.
To get the most accurate readings, it is recommended that you wear your Fitbit moderately snugly and higher on your wrist (toward your elbow).

Fitbit's sleep tracking function is robust and offers a seven-day battery life
Fitbit's sleep-tracking function is robust and offers a seven-day battery life, making it a convenient tool for monitoring your sleep patterns. Here's how it works:
Understanding Sleep Tracking with Fitbit
Fitbit's sleep tracking function provides insights into your sleep patterns and quality. It automatically detects your sleep when worn on the wrist, recommending a snug fit for accurate tracking. Fitbit devices with heart rate tracking (excluding Charge HR and Surge) offer more detailed sleep stage analysis.
Sleep Stages and Insights
Fitbit estimates your sleep stages by combining movement and heart rate data. It identifies periods of light sleep, deep sleep, and REM sleep, helping you understand your sleep quality. The Smart Wake feature is particularly useful, as it monitors your sleep stages and wakes you during a light sleep stage, ensuring you feel refreshed.
Battery Life and Convenience
The seven-day battery life of Fitbit fitness trackers and smartwatches is a significant advantage. This extended battery life eliminates the need to choose between nightly tracking and daily wear, providing uninterrupted sleep tracking without frequent recharges.
Customizable Settings
Fitbit allows customization to suit your needs. You can set sleep goals, bedtime reminders, and wake-up times through the Fitbit app. Additionally, the sleep sensitivity setting can be adjusted to Normal or Sensitive mode, depending on your preference for movement detection.
Premium Features
Fitbit Premium offers advanced sleep analysis, including the Sleep Profile feature, which assigns you an animal-like avatar representing your sleep style. This subscription-based service provides a detailed monthly analysis of various aspects of your sleep, enhancing your understanding of sleep quality and quantity.

The Fitbit app allows users to set sleep goals, bedtime reminders, and alarms
The Fitbit app offers a range of features to help you understand and improve your sleep patterns. The app automatically tracks your sleep when you wear your Fitbit device to bed, detecting when your body is completely at rest and you haven't moved for about an hour.
To utilise the sleep features, open the Fitbit app on your phone. From the Today tab, tap the Sleep Duration tile to access your sleep stats. Here, you can view your sleep history, including the time spent awake, restless, and asleep. Additionally, for devices that track heart rate, you can see your sleeping heart rate and gain insights into your sleep stages, such as light sleep, deep sleep, and REM sleep.
Now, let's delve into the specific features mentioned:
Sleep Goals
You can set sleep goals within the Fitbit app to help you maintain a consistent sleep schedule. Tap on the round icon in the top left corner of the app, then tap "Activity and Wellness" > "Sleep" > "Time Asleep Goal" to adjust your total sleep target. Alternatively, you can access this menu by tapping the gear-like Settings icon in the Sleep menu.
Bedtime Reminders
Bedtime reminders are a helpful feature to keep you on track with your sleep goals. The reminders will notify you when it's time to get ready for bed, helping you stick to a consistent bedtime.
Alarms
Fitbit offers silent alarms, gently waking you with a quiet vibration on your wrist. The Smart Wake feature takes this a step further, monitoring your sleep stages and waking you during a light sleep stage within a 30-minute window before your set alarm time. This ensures you wake up feeling more refreshed.

Fitbit Premium offers a more detailed Sleep Profile and additional insights
The Sleep Profile assigns you a "sleep animal", one of six fun animal characters with distinct sleep behaviours that correspond with common human sleep patterns. For example, a "Bear" tends to have a consistent sleep schedule and falls asleep earlier than most, while a "Dolphin" tends to fall asleep later and sleeps for less time overall. These animals can change from month to month, and the data collected will inform the animal you receive the following month. There is no "ideal" animal, as each one can provide insights into your sleep patterns and how you can improve.
In addition to the Sleep Profile, Fitbit Premium offers other features and insights to help you understand and improve your sleep. With a Premium subscription, you can turn on the snore and noise detection feature, allowing your Fitbit to track noise in your bedroom, including snoring from you or someone next to you. You can also access more detailed information about your sleeping heart rate and restoration, which can provide insights into the quality of your sleep. Fitbit Premium also provides a monthly Sleep Score, which is based on your heart rate, the time you spend awake or restless, and your sleep stages.
Overall, Fitbit Premium offers a comprehensive set of tools and insights to help you better understand your sleep patterns and make informed decisions to improve your sleep quality and overall health.
