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 Google Health sleep stages.

On select devices, Google Health can also track your breathing overnight to check for changes in your blood oxygen levels. For more information, refer to Track your Sleep breathing quality with the Google Health app.

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.

Check your average sleep stats

Check your averages for the week or longer periods of time for certain sleep stats, including:

• Hours slept: The number of hours you slept each night that week and your weekly average.

• Sleep schedule: An overview of your sleep schedule that week which includes your bedtime and wake-up times.

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.
