How Fitbit devices automatically detect sleep

Wrist-based Fitbit devices and Google Pixel Watch series automatically detect your sleep when you wear your device to bed. We recommend you wear your device in a snug wristband during sleep. Do not wear your device in a clip or pendant accessory.

When your body is completely at rest and you haven’t moved for about an hour, your device records that you’re asleep.

What sleep information Fitbit devices track

If your 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. Restless sleep indicates that you move in your sleep, like if you toss and turn. If your device detects excessive movement, enough that restful sleep won't be possible, your device records time spent awake.

Fitbit devices that track heart rate (except Charge HR and Surge) also track sleep stages. Learn more about Fitbit sleep stages.

How time asleep is calculated in the Fitbit app

Your time asleep is calculated by subtracting your time spent awake and restless from your overall tracked sleep time. For example, if you slept 8 hours but woke up 2 times for 15 minutes each, your time asleep would be 7 hours 30 minutes.

Sleep profiles in the Fitbit app

Important: This feature isn't intended to diagnose or treat any medical condition and shouldn't be relied on for any medical purposes. Consult your healthcare professional for questions about your health.

Sleep profile provides a detailed sleep breakdown that is available to you on the first of every month. This breakdown includes 10 monthly metrics and also features a sleep animal that characterizes your long-term sleep behaviors.

Find your sleep profile

To be eligible for a sleep profile, you must meet these requirements:

• Have a Fitbit Premium subscription.
• Use a compatible device: Charge 5, Charge 6, Inspire 2, Inspire 3, Luxe, Pixel Watch series, Sense, Sense 2, Versa 2, Versa 3, or Versa 4.
• Wear your Fitbit during sleep for at least 14 days during the previous month (these do not have to be consecutive days).
• Your sleep logs must include sleep stages data. Learn what sleep stages are and how your Fitbit device detects them.
• Make sure your Fitbit has recently synced. Learn how Fitbit devices sync their data.

The more sleep you log, the more closely your sleep profile will reflect your patterns. You can check how close you are to getting next month's profile on the Sleep tile , located below your sleep graph.

On the first of the month, you may check your sleep profile in the Fitbit app or on your Fitbit device.

In the Fitbit app

From the Today tab , tap Your sleep profile. Scroll down to find a breakdown of your average monthly sleep metrics, including comparisons to other Fitbit users. Metrics include: Sleep schedule variability: How much your sleep schedule varied from day to day. Sleep start time: The time you usually go to sleep. Time before sound sleep: The time it usually takes you to fall soundly asleep. Sleep duration: How long you usually sleep. Deep sleep: The time you spent in deep sleep. REM sleep: The time you spent in REM sleep. Restorative sleep: The time you spent with your heart rate lower than your usual resting heart rate. Sleep stability: How often during your sleep period you were briefly awake or moving. As you change sleep stages or your sleeping position, your brain often wakes up for a moment and then stability tracks how often this happens. Nights with long awakenings: How often you experience awakenings that last around 30 minutes or longer. Days with naps: How often your Fitbit device tracked naps.

How to turn on snore and noise detection

Important:

• This feature is available with a Fitbit Premium subscription.
• This feature impacts your device’s battery, so we recommend charging your device to at least 40% before going to bed. If your device runs out of battery during the night, the noise level chart will be missing some data.
• Your device isn’t able to identify whether snoring comes from you, someone sleeping nearby, or even a pet.
• You must wear your Fitbit device during sleep to collect snore and noise data and your sleep must be at least 3 hours long in order to receive a Snore & Noise Report.
• We only use the microphone to register noise level and snores. We don’t save any audio recordings.
• This feature isn't intended to diagnose or treat any medical condition and shouldn't be relied on for any medical purposes. It is intended to provide information that can help you manage your well-being. If you have any concerns about your health, talk to a healthcare provider.

The snore and noise detection feature allows the microphone on your Fitbit Sense or Fitbit Versa 3 to track noise while you sleep. By analyzing noise information every few seconds, your device can track the overall noise level of your surroundings and check for snoring throughout the night. When you wake up, your nightly results are summarized in a report.

To turn on or turn off snore and noise detection:

1. Open the Fitbit app .
2. From the Today tab , tap the Sleep duration tile.
3. Tap the menu icon at the top right Settings.
4. Turn on Snore & noise detect. When you turn on snore and noise detection for the first time, follow the on-screen instructions.

Tip: If there’s too much background noise, your device’s microphone can’t pick up snoring. For best results, do not play white noise or other ambient sounds during sleep.

To check your snore and noise report:

1. Wear your Fitbit device to sleep. Snore and noise detection doesn’t analyze previous nights’ sleep. You receive your first report the day after you turn on the feature.
2. When you wake up, open the Fitbit app on your phone. From the Today tab , tap the Sleep duration tile.
3. Swipe to the bottom of the page and tap the Snoring & Noise tile to show your "Snore & Noise Report." Your report shows the amount of time your device detected snoring and a chart of the noise level throughout the night.
   • The amount of snoring is categorized as:
     • None to mild (less than 10% of the total time you were asleep)
     • Moderate (10% to 40% of the total time you were asleep)
     • Frequent (more than 40% of the total time you were asleep)
   • The noise level chart shows the volume of your sleeping environment in A-weighted decibels (dBA). The dBA metric measures the relative loudness of sounds to the human ear. A dBA of 0 doesn’t mean there’s no sound, but that it’s not audible to the human ear. For example, a soft whisper is 30 dBA and a coffee grinder is 70-80 dBA. Your overall noise level is categorized as:
     • Very quiet (30 dBA or lower)
     • Quiet (30-50 dBA)
     • Moderate (50-70 dBA)
     • Loud (70-90 dBA)
     • Very loud (90 dBA or higher)

To delete snore and noise data:

1. Visit the Manage your Fitbit Data page in your web browser.
2. In the "Snore & Noise Detect" section, select the start date and end date of the data you want to delete, then tap Delete.

How to set a sleep schedule in the Fitbit app

To help you achieve your sleep goals and establish a consistent sleep routine, use the Fitbit app to set a sleep schedule. You can set either a bedtime or a wake-up time target, or set both targets.

If you meet your target when you go to sleep or wake up within 30 minutes of the target, a star appears in the sleep schedule graph. You won’t find a star If you set both bedtime and wake-up time targets but only meet one.

How Fitbit estimates your sleep time

If you have 5 or more sleep logs, your sleep goal is estimated based on an average of these logs. Your wake-up time target is estimated based on the time you typically wake up each day. Your bedtime target defaults to the time you should go to sleep in order to meet your sleep goal.

If you have fewer than 5 sleep logs, you can provide an estimate of how much sleep you get on a typical night. Your sleep goal is set based on this estimate. You must manually set your bedtime and wake-up time targets.

Set up your bedtime, wake time, or sleep duration targets

Android phones

1. Open the Fitbit app .
2. From the Today tab , tap the Sleep duration tile.
3. Tap the menu icon at the top right Settings.
4. Tap Bedtime, Wake Time, or Sleep duration to set or edit your targets.

iPhones

1. Open the Fitbit app .

How sensitive mode differs from normal sleep mode

For devices that record sleep patterns instead of sleep stages, you can set your device to track sleep in a normal or sensitive mode.

• Normal mode: When you make significant movements like rolling over, your device records time spent awake. This setting is appropriate for most users.
• Sensitive mode: Your device records nearly all movements as time spent restless or awake. This setting may be helpful if you wake up feeling tired even though your sleep history shows sufficient rest.

Troubleshooting sleep

I can’t find my sleep session

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 (or if it syncs but your sleep session doesn’t appear), follow these steps:

1. Open the Fitbit app .
2. From the Today tab , touch and hold on the screen and pull down to refresh.
3. If your Fitbit device didn’t sync, force quit the Fitbit app and restart your phone’s Bluetooth connection.
4. Try to manually sync your Fitbit device again. If you still experience issues, learn why your Fitbit device doesn’t sync.

My sleep duration or the time I fell asleep seems inaccurate

• Check if your sleep setting is set to Sensitive. If it is, change it to Normal. For instructions, refer to the section above on how to change your sleep sensitivity setting.
• To accurately track your sleep, make sure your device is positioned higher on your wrist, about 2-3 finger widths above the wrist bone. The band should feel secure but not too tight. For detailed instructions, check out How do I wear my Fitbit device?
• To adjust a sleep session’s start or end time, edit it in the Fitbit app. For instructions, refer to How do I add, edit, or delete Fitbit data and activities?
