Fitbit devices offer a sleep-tracking function that provides insights into your sleep patterns and quality. The sleep-tracking feature is available on both the free and premium versions of the Fitbit app. The free version offers basic insights, while the premium subscription provides more detailed information, including a monthly Sleep Profile analysis of your sleep habits. Fitbit's sleep tracking uses an accelerometer and optical photoplethysmography (PPG) to infer when you're sleeping and what stage of sleep you're in. The device also uses your heart rate and movement data to create a Sleep Score, which accounts for sleep duration, quality, and restoration. The sleep sensitivity setting can be adjusted to either 'Normal' or 'Sensitive' to fine-tune the tracking to your needs.

Fitbit's sleep tracking function can monitor sleep stages and wake you during light sleep
Fitbit's sleep-tracking function offers a detailed insight into your sleep patterns and quality. The function monitors your sleep stages and can wake you during a light sleep stage, ensuring you feel more refreshed when you wake up.
The sleep-tracking function is available on all Fitbit fitness trackers and smartwatches. It records your sleep patterns and sleep stages, including light sleep, deep sleep, and REM sleep. Light sleep, which usually occurs in the second half of the night, promotes mental and physical recovery. Deep sleep, which typically occurs in the first few hours of sleep, is a restorative phase for the mind and body, and is when breathing slows down, muscles relax, and the heart rate becomes more regular. REM sleep, which is associated with vivid dreams, also usually occurs in the latter half of the night. During this stage, brain activity increases, and the eyes move rapidly.
The sleep-tracking function allows you to set a sleep schedule and bedtime reminders to help you maintain a consistent sleep pattern and wind down each night. You can also set a silent alarm to wake you up gently during a light sleep stage. This feature, called Smart Wake, monitors your sleep stages and wakes you up gently during a 30-minute window before your set alarm time. For example, if your alarm is set for 7:00 am, Smart Wake may wake you up anytime between 6:30 am and 7:00 am. This feature ensures you wake up feeling more rested and energised.
Additionally, Fitbit's sleep-tracking function provides a comprehensive analysis of your sleep duration, sleep score, and sleep schedule. It offers weekly averages for hours slept, sleep score, and time spent in each sleep stage. With a Premium subscription, you can also access features like snore and noise detection, which uses the device's microphone to track noise levels and snoring. This information can be useful for your own reference or to share with a doctor if you have concerns about your sleep health.
To optimise the sleep-tracking function, ensure your Fitbit is positioned snugly and higher on your wrist, about 2-3 finger widths above the wrist bone. It is also recommended to have at least a 40% charge on your device before sleep, as this function can affect battery life.

The device can be set to track sleep in normal or sensitive mode
The Fitbit device can be set to track sleep in normal or sensitive mode. The normal setting counts significant movements, such as rolling over, as being awake, while the sensitive setting records all movements as time spent restless or awake. This feature is useful for those who tend to move around a lot in their sleep.
To adjust the setting, open the Fitbit app and tap the setting icon on the top right of the Sleep page. Then, tap Sleep Sensitivity and select either Sensitive or Normal. It is important to note that the sensitive setting may not be as accurate as the normal setting, as it can result in false positives. For example, it may record you as being awake even when you are just moving slightly.
Additionally, Fitbit devices with a heart rate tracker can provide more detailed sleep tracking information. These devices can track sleep stages, including time spent awake, restless, and asleep. The Fitbit app also offers a Sleep Profile feature, which provides a personalized monthly analysis of your sleep habits, including how long you slept and how many naps you took.
To accurately track your sleep, ensure that your Fitbit device is positioned snugly on your wrist, about 2-3 finger widths above the wrist bone. The band should feel secure but not too tight.

The sensitive mode records nearly all movements as time spent awake or restless
Fitbit devices have a robust sleep tracking function that can help you understand your sleep patterns and quality. The sleep tracking function is available on the Fitbit app, which offers both free and premium versions. The free version allows you to track your sleep, along with your activity, nutrition, and weight, and provides some basic insights. On the other hand, the premium subscription offers more advanced insights into your sleep, including a Sleep Profile—a personalized monthly analysis of your sleep habits based on various factors, such as how long you slept and how many naps you took.
When it comes to sleep tracking, Fitbit devices offer two settings: Normal mode and Sensitive mode. Normal mode is the default setting, which records significant movements, such as rolling over, as time spent awake. This setting is suitable for most users.
However, for those who want a more detailed analysis of their sleep, Fitbit offers the Sensitive mode. In this mode, the device captures nearly all movements, no matter how small, as time spent restless or awake. This setting can be particularly useful for individuals who consistently feel tired even after their sleep history indicates they had sufficient rest. By using Sensitive mode, they can gain a better understanding of their sleep patterns and make necessary adjustments to improve their rest.
It is important to note that the Sensitive mode may result in a higher number of false positives, where the device records time as awake or restless even when the user did not recall waking up. This can lead to lower sleep efficiency percentages, giving the impression of more restless nights than actual. As a result, some users might prefer the Normal setting as it provides a more comprehensive overview of their sleep duration.
To access the sleep sensitivity settings on your Fitbit device, open the Fitbit app and go to the Feature settings section. From there, tap on Sleep Sensitivity and make your desired changes. Additionally, ensure that your device is positioned higher on your wrist, about 2 to 3 finger widths above the wrist bone, for more accurate sleep tracking.

The normal mode is suitable for most users as it records time spent awake when significant movements are made
Fitbit devices offer a robust sleep tracking function that can help you understand your sleep patterns and quality. The sleep tracking function is available on both the free and premium versions of the Fitbit app. The free version of the app lets you track your sleep and offers some basic insights, while the premium subscription gives you more insight into your sleep, including your Sleep Profile—a personalized monthly analysis of your sleep habits.
The sleep tracking function on Fitbit devices records sleep patterns instead of sleep stages. It offers two modes: Normal and Sensitive. The Normal mode is suitable for most users as it records time spent awake only when significant movements are made, such as rolling over. This mode is suitable for users who want an overview of how long they have been asleep and is also useful for identifying especially bad nights of sleep.
The Sensitive mode, on the other hand, records nearly all movements as time spent restless or awake. This includes very small movements. This setting may be helpful for those who wake up feeling tired despite their sleep history showing sufficient rest. It may also be useful for those who wear the Fitbit device elsewhere on their body or for those with sleep disorders. However, it is important to note that the Sensitive mode may result in a higher number of "false positives" for restlessness or wakefulness.
You can adjust the sleep sensitivity setting on your Fitbit device by opening the Fitbit app and tapping the "Feature settings" or "Sleep sensitivity" option. It is recommended to have your device charged to at least 40% before bed as the sleep tracking function affects battery life. Additionally, ensure that your device is positioned higher on your wrist, about 2-3 finger widths above the wrist bone, for accurate sleep tracking.

Fitbit's sleep tracking function can help users understand their sleep patterns and quality
Fitbit smartwatches and fitness trackers have a robust sleep-tracking function that can help users understand their sleep patterns and quality. The sleep-tracking function can be accessed through the Fitbit app, which offers both free and premium versions. The free version allows users to track their sleep and provides basic insights, while the premium version offers more in-depth analysis, including a monthly Sleep Profile based on factors such as sleep duration and the number of naps taken.
The Fitbit device uses an accelerometer to infer when the user is sleeping and what stage of sleep they are in. It also employs a technique called optical photoplethysmography (PPG), which measures blood flow by reflecting green light from an LED on the back of the watch onto the body. This method allows the Fitbit to classify sleep stages with 69% accuracy in any given 30-second time window, according to a 2017 paper published by Fitbit scientists.
Fitbit's sleep-tracking sensitivity settings offer two options: "Normal" and "Sensitive". The "Normal" mode records significant movements, such as rolling over, as time spent awake, while the "Sensitive" mode captures nearly all movements as time spent restless or awake. The "Sensitive" setting may be useful for individuals who wake up feeling tired despite their sleep history indicating sufficient rest. However, some users have reported false positives with this setting, where they feel well-rested but the Fitbit records lower sleep efficiency.
Additionally, Fitbit's Smart Wake feature monitors sleep stages and wakes the user during a light sleep stage within a 30-minute window before their set alarm time. This feature aims to ensure that users wake up feeling more refreshed. To enhance the accuracy of sleep tracking, users should ensure their Fitbit is positioned higher on their wrist, about 2-3 finger widths above the wrist bone.
