Fitbit devices have a robust sleep-tracking function that can help you improve your sleep by understanding your sleep patterns. To set up sleep tracking on your Fitbit Charge 3, ensure your device is charged to at least 40% before bed, as the feature affects battery life. You can then adjust your sleep sensitivity settings, and set your sleep goals in the Fitbit app. Once you've woken up, your tracker will sync with your phone and provide a readout of your sleep, including a sleep score out of 100. This score reflects the quality of your sleep and is calculated based on your heart rate, movements, and time spent in each sleep stage.

What You'll Learn
Understanding your sleep score
Your Fitbit Charge 3 will give you a sleep score based on a number of metrics. This feature gives you an insight into your sleeping habits and the quality of sleep you get each night. The overall number is reported on a scale of 0 to 100, along with a one-word description like "good" or "fair". The sleep score is calculated based on your heart rate, the time you spend awake or restless, and your sleep stages.
The overall sleep score is the sum of your individual scores for time asleep, deep and REM sleep, and restoration, for a total score of up to 100. The average score ranges from 72 to 83. Restoration provides insight into how restful your sleep was and is based on your sleeping and resting heart rates and how much time you spent tossing and turning. You receive a higher restoration score when your sleeping heart rate is lower than your daytime resting heart rate.
To improve your sleep score, work on your overall sleep habits, heart health, and activity levels. Exercise earlier in the day or at least 3 to 4 hours before you sleep. Maintain a consistent sleep schedule and meet the CDC's recommended 150 active minutes per week.
Fitbit Premium offers several tools that can help you get better sleep, including a daily sleep score breakdown that can help you understand where you can improve your sleeping habits and receive personalized guidance. The premium service also includes guided programs developed with sleep experts, including "Habits for Restful Sleep" and "Get More Sleep".

Setting up sleep tracking on the Fitbit app
To set up sleep tracking on the Fitbit app, you'll first need to ensure your Fitbit is charged to at least 40% to avoid the device running out of battery during the night. Once charged, you can wear your Fitbit to sleep and it will automatically start tracking your sleep after you've been still for an hour.
If you have a Fitbit Sense or Versa 3, you can turn on snore and noise detection in the app by tapping the 'Sleep duration' tile on the 'Today' tab, then tapping Settings and turning on 'Snore & Noise Detect'. This feature uses the microphone on your Fitbit to track the overall noise level of your surroundings and check for snoring throughout the night.
You can also set a sleep schedule for yourself in the Fitbit app. To do this, tap the cog icon on the 'Sleep' page and set your sleep goals. The app will then remind you when it's time for bed, based on the bedtime and wake-up times you've set.
In the morning, your Fitbit will register that you're awake and stop tracking your sleep. You can then sync your Fitbit with your phone to view a breakdown of your sleep stages, including REM, light, and deep sleep. You'll also receive a sleep score out of 100, which reflects the quality of your sleep.

Adjusting sleep sensitivity settings
To adjust the sleep sensitivity settings on your Fitbit Charge 3, you can follow these steps:
- Ensure that your Fitbit is charged to at least 40% before going to bed. The sleep tracking feature consumes battery power, and a charge of at least 40% is recommended for accurate tracking throughout the night.
- Wear your Fitbit device during sleep. To track your sleep accurately, it is important to wear your Fitbit comfortably but securely on your wrist, positioned slightly higher than your wrist bone (about 2-3 finger widths above).
- Access the settings on your Fitbit device or the Fitbit app. If you are using the app, tap on the gear icon in the upper right corner, then select "Settings" from the dropdown menu.
- Locate the sleep sensitivity settings. In the settings menu, scroll down to the Advanced Settings section. Here, you will find the sleep sensitivity settings near the bottom.
- Choose between "Normal" and "Sensitive" modes. The "Normal" mode records significant movements, such as rolling over, as being awake. This setting is suitable for most users. On the other hand, the "Sensitive" mode captures almost all movements as time spent restless or awake. This mode is beneficial for individuals who consistently wake up feeling tired despite their sleep history indicating sufficient rest.
- Adjust the setting based on your preference and sleep patterns. If you are unsure, it is generally recommended to start with the "Normal" mode, as it provides a more basic understanding of your sleep patterns. The "Sensitive" mode may capture excessive restlessness, leading to potentially inaccurate sleep data.
- Review your sleep logs and make adjustments as needed. After using the sleep tracking feature for a few nights, review the sleep data in your Fitbit app. If you find that the "Normal" mode is not capturing your restless nights or tiredness, you can consider switching to "Sensitive" mode for more detailed sleep reporting.
Remember that the sleep sensitivity settings may impact your battery life and sleep data. It is essential to find the setting that best suits your sleep patterns and preferences. Additionally, ensure that your Fitbit is worn correctly and positioned comfortably on your wrist for the most accurate sleep tracking results.

Syncing your Fitbit with your phone
To access this data, you can open the Fitbit app on your phone and go to the "Today" or "Sleep" tab, where you can view your total sleep duration and Sleep Score. From here, you can also access more detailed information by scrolling down to the snoozing moon icon, which represents Sleep. This will show you a breakdown of the different sleep stages, including REM, light, and deep sleep.
Additionally, you can set your sleep goals and bedtime reminders within the Fitbit app. By setting your bedtime and wake-up times, the app can remind you when it's time to go to sleep. The Fitbit will automatically detect when you're awake and stop tracking your sleep.
It's important to note that the accuracy of sleep tracking depends on factors such as the fit of your device and its position on your wrist. Ensure that your Fitbit is positioned securely about 2-3 finger widths above your wrist bone. If you encounter any syncing issues, you can try manually syncing your device again and checking your sleep sensitivity settings.

Using the snore and noise detection feature
The "Snore and Noise Detect" feature is currently only available for the Fitbit Sense and Versa 3 models, with a Premium subscription. This feature is not available on the Fitbit Charge 3 as it does not have an onboard microphone or speaker.
To set up the "Snore and Noise Detect" feature on the Fitbit Sense and Versa 3, follow these steps:
- Ensure your Fitbit has at least a 40% battery before going to sleep. The "Snore and Noise Detect" feature consumes a significant amount of battery life, so it is recommended to charge your device more frequently when using this feature.
- Open the Fitbit app on your smartphone and go to the Sleep page.
- On the "Sleep" page, you will see a Check for Snoring option. Click on "Learn More" to read about the "Snore and Noise Detect" feature.
- Click "Next", agree to the privacy policies, and enable the feature to record your noise levels at night.
- Make sure your Fitbit's microphone is turned on in the settings to allow the app to collect audio information. Go to Settings > Vibration & Audio Settings and turn on the microphone.
- Once the feature is enabled, wear your Fitbit while sleeping, and it will track snoring and other noises during your sleep cycle.
- To access the "Snore Report", open the Fitbit app, tap the Sleep tile on the "Today" tab, tap Restoration, and then select View Snore & Noise Report.
The "Snore Report" will provide insights into two factors: noise level and snoring events. The noise level will be presented in a chart with dBA (relative decibels) on the y-axis and time on the x-axis. The snoring events section will represent the amount of time spent snoring during sleep, shown as a percentage.
