Fitbit's sleep tracking function is a useful feature that allows users to understand their sleep patterns and quality. Fitbit Inspire 2 users have reported issues with the sleep mode, with the device often failing to record an entire night's sleep. Troubleshooting steps such as restarting the device, updating the software, and checking the sensor for damage can help resolve these issues. Fitbit's sleep tracking uses movement and heart-rate patterns to estimate sleep cycles, with additional data on movement and heart rate variability confirming sleep status. The device also offers a sleep profile with 10 monthly metrics and a sleep animal characterisation for long-term sleep behaviour analysis.

Sleep tracking
The Fitbit Inspire 2 will automatically detect your sleep when you wear it to bed. The device assumes you are asleep when your body is completely at rest and you haven't moved for about an hour. It tracks your sleep by monitoring your movement and heart rate patterns. The 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.
You can also manually adjust a sleep session's start or end time in the Fitbit app. If you are experiencing issues with sleep tracking, you can try restarting your Fitbit Inspire 2, ensuring that sleep tracking is turned on in the app, updating your Fitbit to the latest software, or factory resetting your device. Additionally, you can check if your sleep setting is set to sensitive and change it to normal if necessary.
The Fitbit app provides a detailed sleep breakdown, including a sleep score and sleep profile. The sleep score is reported on a scale of 0 to 100, along with a one-word description like "good" or "fair". The sleep profile, available with a Fitbit Premium subscription, provides a monthly breakdown of your sleep metrics and assigns you a sleep animal based on your sleep habits.

Sleep stages
While you sleep, your Fitbit device tracks the beat-to-beat changes in your heart rate, known as heart rate variability (HRV), which fluctuates as you transition between different sleep stages. These stages include light sleep, deep sleep, and REM sleep. Light sleep serves as your entry point into sleep each night as your body unwinds and slows down. Deep sleep is characterised by less brain activity than REM sleep. Periods of deep sleep are typically longer earlier in the night, while REM sleep, or rapid eye movement sleep, is associated with vivid dreams and longer periods towards the end of the night.
To accurately track your sleep stages, it is important to wear your Fitbit device correctly. It is recommended to wear the device in a snug wristband during sleep, positioned higher on your wrist, about 2-3 finger widths above the wrist bone. The band should feel secure but not too tight. Additionally, ensure that sleep tracking is turned on in the Fitbit app. If you are experiencing issues with sleep tracking, try restarting your Fitbit device or updating it to the latest software version.

Sleep score
Fitbit's sleep tracking feature provides a detailed analysis of your sleep. The Fitbit Inspire 2™ is a wrist-worn device that automatically detects your sleep when worn to bed. It is recommended that you wear your device in a snug wristband, positioned higher on your wrist, about 2-3 finger widths above the wrist bone. This ensures the device can accurately track your sleep.
The Fitbit Inspire 2™ uses a motion sensor and heart rate measurement to monitor data at regular intervals for waking and sleeping times. This data is used to calculate your Sleep Score, which is a number between 0 and 100 that gives you an overview of your sleep quality. A higher score indicates better sleep. The Sleep Score is based on several metrics, including sleep duration, sleep stages, and restlessness.
To view your Sleep Score, you can swipe up on your Fitbit device, which will display the previous night's Sleep Score. For more detailed information, you can sync your Fitbit with your phone and open the Fitbit app. The app will show your Sleep Score, bedtime, wake time, and time spent in different sleep stages. It also provides visual representations of your sleep data, allowing you to compare your sleep patterns over time.
It's important to note that the Sleep Score is not intended to diagnose or treat any medical conditions. If you have specific concerns about your sleep or health, it is advisable to consult a healthcare professional. Additionally, ensure that you keep your Fitbit app and firmware updated to the latest version for accurate results.

Sleep profile
The sleep profile assigns you a sleep animal—a bear, dolphin, giraffe, hedgehog, parrot, or tortoise—based on how your sleep metrics compare to the sleep profiles created by Fitbit. For example, bears tend to have a consistent sleep schedule and fall asleep quickly. To get a Sleep Animal profile, you need to wear your device to bed for 14 nights in a given month.
The Fitbit sleep tracking function works by automatically detecting your sleep when you wear your device to bed. It is recommended to wear your device in a snug wristband during sleep, positioned higher on your wrist, about 2-3 finger widths above the wrist bone. The band should feel secure but not too tight. When your body is completely at rest and you haven't moved for about an hour, your device records that you're asleep.
Your time asleep is calculated by subtracting your time spent awake and restless from your overall tracked sleep time. Fitbit devices that track heart rate can also track sleep stages, such as light sleep, deep sleep, and REM sleep. Sleep stages are estimated using your movement and heart rate patterns.

Troubleshooting sleep mode
If your Fitbit Inspire 2 is not tracking your sleep, there are a few troubleshooting steps you can try. Firstly, ensure that your Fitbit is correctly paired and synced with your smartphone. You can also try to remove the device from the app and set it up again.
If the issue persists, check if your sleep setting is set to "Sensitive". If it is, change it to "Normal". Additionally, make sure that your Fitbit is positioned higher on your wrist, about 2-3 finger widths above the wrist bone, and that the band is secure but not too tight.
If your Fitbit still fails to track your sleep, try restarting your device. To do this, go to the Settings app, scroll down to "About", and tap "Restart Device". You can also check to make sure that sleep tracking is turned on by going to Account > Inspire 2 > Sleep > Sleep Tracking in the Fitbit app on your phone.
If your Fitbit is not running the latest software, it may have issues with sleep tracking. To check for updates, go to the Settings app, scroll down to "About", and tap "Update Device". If none of these steps work, you could try factory resetting your Fitbit Inspire 2. However, this will erase all data from your device, so ensure that you have synced your data to the app before resetting.
If your Fitbit continues to have issues with sleep tracking, it may be due to a faulty sensor. The green light on the back of your Fitbit is used to measure your heart rate and track your sleep. If the light is not working, clean the sensor with a soft, damp cloth and ensure that it is dry before putting it back on. If the sensor is damaged, you may need to contact Fitbit support for further assistance or to arrange a replacement.
