What You'll Learn
Fitbit sleep tracking: Wrist vs pendant
Fitbit sleep tracking has evolved to offer detailed insights into your sleep patterns and quality. While the Fitbit app plays a central role in understanding your sleep, the placement of your Fitbit device is crucial for accurate tracking. Here's a comparison of wrist-based and pendant-style Fitbit sleep tracking:
Wrist-based Fitbit Sleep Tracking
Wrist-based Fitbit devices, including the Google Pixel Watch series, are designed to automatically detect your sleep when worn snugly on the wrist during sleep. This detection is based on your body's inactivity and lack of movement for about an hour. It is recommended to position the device 2-3 finger widths above the wrist bone, ensuring the band is secure but not overly tight. This placement is important for accurate sleep tracking, as it allows the device to monitor your heart rate and track sleep stages.
Wrist-based tracking offers the advantage of heart rate monitoring, which is essential for advanced sleep metrics and features like Active Zone Minutes. It also enables automatic sleep detection, making it convenient for users who want a seamless sleep tracking experience. However, some users have reported discomfort with wrist-based tracking, especially those with sensitive skin or conditions like eczema.
Pendant-style Fitbit Sleep Tracking
Fitbit offers alternative form factors, such as clip-on trackers and pendants, that can be worn as necklaces or pendants. These options provide discreet tracking for users who prefer not to wear a device on their wrists. While pendant-style tracking can be more comfortable and aesthetically pleasing for some, it comes with limitations in sleep tracking capabilities.
Pendant-style trackers may not have direct access to heart rate data, which is crucial for in-depth sleep analysis. As a result, users may need to place the device back on the wrist to enable heart rate tracking during sleep. Additionally, automatic sleep detection may not work as effectively with pendant-style trackers, requiring manual adjustments in the app.
In conclusion, wrist-based Fitbit sleep tracking offers more comprehensive insights due to direct heart rate monitoring and seamless sleep detection. However, pendant-style tracking can be a comfortable and discreet alternative for those who prioritize comfort or prefer a different form factor. It's important to note that Fitbit officially recommends using the wrist-based option for sleep tracking, as pendants or clips may not provide the same level of accuracy.

Sleep sensitivity settings
Sleep tracking on Fitbit devices can be adjusted through the sleep sensitivity settings. This feature allows users to customise how their device records sleep patterns and stages. The sleep sensitivity settings can be found by opening the Fitbit app, tapping on the "Today" tab, and accessing the settings through the user's profile picture. From there, users can navigate to the “Preferences” section and select “Sleep”. The “Sleep Sensitivity” option will be available in the “Feature Settings” section.
The sleep sensitivity settings offer two main modes: "Normal" and "Sensitive". The "Normal" mode provides a more basic idea of a user's sleep patterns, while the "Sensitive" mode offers extremely detailed sleep reporting. In "Sensitive" mode, the device records nearly all movements as time spent restless or awake. This mode may be useful for individuals who wake up feeling tired despite their sleep history indicating sufficient rest.
It is important to note that the sleep sensitivity settings may have a limited impact on newer Fitbit devices that can detect heart rate. These devices use heart rate data to track sleep stages, which may result in more accurate sleep tracking compared to older devices that rely solely on movement detection.
Additionally, other factors can affect sleep tracking accuracy. For example, the placement of the device on the wrist can impact its ability to record sleep properly, especially if the user has tattoos or sleeves that cover the sensor. It is recommended to wear the device on the wrist without any tattoos or ink to ensure optimal tracking.
Users experiencing issues with sleep tracking are advised to check their device's battery level, sync status, and heart rate tracking functionality. Adjusting the sleep sensitivity settings and ensuring optimal device placement can help improve the accuracy of sleep tracking on Fitbit devices.

Heart rate and movement patterns
Fitbit devices are known for their sleep-tracking abilities. They are equipped with powerful heart rate monitors and other health-tracking sensors to help you keep tabs on your resting heart rate and overall fitness. The devices track sleep stages like REM, deep, and light sleep.
Fitbit estimates sleep stages by using heart rate and movement patterns. It automatically assumes you are asleep when you don't move for about an hour. The device confirms you are sleeping using additional information about your movements. Your heart rate variability (HRV) changes in each sleep stage. Fitbit tracks the transitions and uses the patterns to monitor your sleep.
When you wake up in the morning and sync your device, it gives you a sleep score based on the sleep cycles from the previous night. Fitbit devices that don't track heart rate show your sleep pattern in the Fitbit app. The sleep stats include time spent awake, restless, and asleep. Restless sleep includes movements like tossing and turning.
If your Fitbit device doesn't track heart rate, you can check your sleep pattern in the Fitbit app. Your sleep pattern includes your time spent awake, restless, and asleep. If your device detects excessive movement, enough that restful sleep won't be possible, your device records time spent awake.
If your Fitbit device’s battery isn’t critically low, check when the Fitbit device last synced. Your Fitbit will usually sync automatically when it's near your phone and you open the Fitbit app. If it doesn't sync, follow these steps: Open the Fitbit app, then touch and hold on the screen and pull down to refresh. If your Fitbit device didn’t sync, force quit the Fitbit app and restart your phone’s Bluetooth connection.
