If your Fitbit Alta 2 is not tracking your sleep, there could be a few reasons. Firstly, it is important to check if your device is set up correctly. This includes ensuring that the heart rate tracking is turned on in your settings, as the device registers sleep by analyzing heart rate and motion patterns. Additionally, the position and snugness of the band can impact the accuracy of sleep tracking. It is recommended to wear the device snugly about an inch above the wrist bone, as suggested by Fitbit. If these basic checks do not resolve the issue, you may need to restart your device or adjust some of its settings. It is also worth noting that tattoos and arm hair can interfere with the heart rate monitor, so this may be a factor if your device is still not tracking sleep.

What You'll Learn
Alta HR and Charge 2 users should check that heart rate tracking is on in their settings
The Fitbit Alta HR is an upgrade to the original Alta, with the addition of a heart rate monitor. This allows for greater accuracy in tracking the calories you burn and results in a more detailed breakdown of sleep. The Alta HR can now also give an estimate of your resting heart rate, which is a good indicator of general fitness. The heart rate monitoring feature is also available on the Fitbit Charge 2.
The Alta HR differs from the Charge 2 in terms of the sample rate for heart rate readings. The Alta HR takes a reading every five seconds, while the Charge 2 does so every second, resulting in better real-time updates. This is especially important for interval training. The Charge 2 also has an altimeter to count stairs climbed, which the Alta HR does not have.
Both devices offer continuous heart rate reading during exercise, which can tell you how hard you are working and which heart rate zone you are in. This is useful if you are training with a specific purpose in mind, such as fat burning or improving your aerobic performance.
To ensure that your Fitbit Alta HR or Charge 2 is accurately tracking your sleep, it is important to check that heart rate tracking is turned on in your settings. This will ensure that the device can monitor your heart rate throughout the night and provide a detailed breakdown of your sleep stages, including REM, light sleep, and deep sleep.
In addition to checking your settings, make sure that your Fitbit is snug enough on your wrist. If it is too loose, it may not be able to get a clear heart rate reading, which can affect the accuracy of your sleep tracking.

Try wearing the Fitbit on the inside of the wrist
If your Fitbit Alta 2 is not tracking your sleep, you could try wearing the device on the inside of your wrist. This is because the Fitbit needs to be positioned higher on your wrist, about 2-3 finger widths above the wrist bone, to accurately track your sleep. The band should be snug but not too tight.
Wrist-based Fitbits automatically detect your sleep when you wear them to bed. They record that you are asleep when your body is completely at rest and you have not moved for about an hour. If your Fitbit doesn't track your heart rate, you can still check your sleep pattern in the Fitbit app, which will show your time spent awake, restless, and asleep. If your Fitbit does track your heart rate, it will also track your sleep stages.
The Alta HR is geared towards capturing augmented sleep tracking data rather than being an exercise companion. It has a continuous heart rate reading during exercise, which will tell you how hard you are working and which heart rate zone you are training in. However, the sample rate for heart rate readings is only every five seconds, which is less frequent than other Fitbit trackers.
The Alta HR also has a silent alarm, which vibrates on your wrist at the specified time. This is useful if you share a bed with someone who has a different waking time to you.

Ensure the Fitbit is snug on the wrist
If your Fitbit Alta 2 is not tracking your sleep, it could be due to the position and snugness of the band. It is important to ensure that the Fitbit is snug on your wrist, as this will help the device to accurately detect your heart rate and motion patterns, which are crucial for sleep tracking.
To ensure the Fitbit is snug on your wrist, adjust the band to a comfortable notch. If you wear the band too loose, it may move during sleep towards your wrist bone, resulting in sporadic sleep data. However, it is important to find a balance, as wearing the band too tight can be uncomfortable. As a general guideline, Fitbit recommends wearing the device snugly, about an inch above your wrist bone.
If you experience redness or dryness on your wrist due to the snug fit, try wearing the Fitbit on your opposite wrist for sleeping. This can help alleviate the skin irritation while still allowing for accurate sleep tracking. You can also try turning the tracker around so that the pulse tracker is against the inside of your wrist, as this has been reported to improve sleep stage tracking for some users.
Additionally, ensure that your Fitbit Alta 2 is set to "on wrist" in the settings, as having it set to "on clip" will affect sleep tracking, even if the device is worn on the wrist. By following these suggestions, you can improve the chances of your Fitbit Alta 2 accurately tracking your sleep patterns.

Check the battery is charged
If your Fitbit Alta 2 is not tracking your sleep, it could be due to a low battery. To ensure this is not the issue, check that your device is sufficiently charged.
To check the battery life of your Fitbit Alta 2, start by pressing the button on the side of the device. If the battery is charged, a smiley face will appear. If the battery is low, a frown will appear. If you see a frown, plug your charging cable into the USB port on the back of your Fitbit. Once the cable is plugged in, connect the cable to a power source such as a computer or a wall adapter. You can continue to wear your Fitbit while it charges, or you can place it on a flat surface to charge.
It is important to note that if your Fitbit is not tracking your sleep, it may be due to other factors. For example, the Fitbit Alta 2 may not be tracking your sleep if the heart rate tracking setting is turned off. Additionally, the position and snugness of the band can impact the accuracy of sleep tracking. If the band is too loose, it may move during sleep, resulting in sporadic sleep data.
If your Fitbit Alta 2 is still not tracking your sleep after checking the battery and adjusting the band, you may need to restart the device or adjust other settings.

Restart the device
If your Fitbit Alta 2 is not tracking your sleep, restarting your device may help. Restarting your Fitbit can fix glitches like inaccurate step-counting or slow running, which may be interfering with its ability to track your sleep.
To restart your Fitbit Alta 2, go to "Settings" and then "Reboot Device". If you have a Fitbit Inspire, make sure it's set to "on wrist" instead of "on clip". If your Fitbit is set to "on clip", it won't record your sleep accurately, even if you wear it on your wrist.
If you're having trouble with heart rate tracking, which is essential for sleep tracking, make sure that this feature is turned on in your settings. If your heart rate isn't being tracked, your sleep won't be either. You can also use the Fitbit app to manually start and stop sleep tracking if your Fitbit isn't doing this automatically.
If your Fitbit Alta 2 still isn't tracking your sleep, you may need to try wearing it in a different position. Try turning the tracker around so that the pulse tracker is against the inside of your wrist. You may also need to adjust the tightness of the band. If the band is too loose, it may move during your sleep, preventing the Fitbit from tracking your sleep accurately.
