Track sleep with Google Health

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.

If your device doesn’t track heart rate, you can check your sleep pattern in the Google Health 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.

Sync your device each morning to review your sleep data, such as your sleep score. You can check this information on your Fitbit device or in the Google Health app.

1. Open the Google Health app  and tap the Today tab Sleep duration.
2. Scroll to "More about your sleep" and tap Sleeping heart rate.

Your time asleep is estimated as all the time in the main sleep period that was identified to be in one of the 3 sleep stages: Light, Deep, or REM.

To help you achieve your sleep goals and establish a consistent sleep routine, use the Google Health 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 15 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.

You can also adjust your sleep goal duration. If you don't select it, a default 7 hour duration is set for you. The sleep goal does impact your sleep score.

• Resolve sleep duration inaccuracies. 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?
