What is the difference between the normal and sensitive sleep setting?
Your Fitbit tracker's settings can record your sleep in either "sensitive" mode for extremely detailed sleep reporting or "normal" mode for a more basic idea of your sleep patterns.
- The normal setting counts significant movements as being awake (such as rolling over) and is appropriate for most users.
- The sensitive setting will cause your tracker to record nearly all movements as time spent restless or awake. This setting may be helpful for users who wake up feeling tired even though their sleep history shows sufficient rest.
To change your sleep sensitivity setting, choose a section. If you use the Fitbit app for Android you must change your sleep sensitivity setting on fitbit.com.
- On your dashboard tap the icon in the top right ( ).
- Tap Advanced Settings and then Sleep Sensitivity.
- On your dashboard, tap or click Account.
- Tap or click Advanced Settings > Sleep Sensitivity.
- Log into your fitbit.com dashboard and click the gear icon in the top right.
- Go to Settings > Devices and scroll down to Sleep Tracking.
What do the different sleep states mean?
During sleep mode, when your body is completely at rest and unmoving, your Fitbit tracker records that you are asleep.
A restless state of sleep indicates that you moved from a very restful position into one involving greater movement, such as turning over in bed. This doesn't necessarily mean that you were fully awake or cognizant of your movements, but it may indicate that you were not getting the most restful sleep possible at that time.
When your tracker indicates that you are moving so much that restful sleep would not be possible, your sleep graph will indicate that you were awake.
How do I see my sleep data?
Be sure to sync your tracker each morning to see last night's sleep stats on your dashboard. Tap the sleep tile on your Fitbit app dashboard to see your sleep history and tap any particular day to see details. Choose your device below for step-by-step instructions. On the fitbit.com dashboard, click the sleep tile to view your recent sleep data.
Time asleep is calculated by subtracting your time awake or restless from the overall tracked time. For example, if you slept eight hours, but woke up two times for 15 minutes each, the time asleep will show 7 hr 30 min. Your sleep quality is based on whether you were asleep, restless, or fully awake.
- Tap the dashboard tile that shows how many hours you slept. (If it says "How did you sleep?" you either didn't wear a tracker last night or your tracker's data hasn't synced with your dashboard.) a particular day to see your sleep graph and sleep quality information.
- Swipe through the graphics at the top to see your hours slept, sleep schedule, and times awake.
- Tap the expander arrow in the top right to open and close information about your sleep averages.
- Tap a particular day to see your sleep graph and sleep quality information.
- On the 1d view, you can see the precise times that you were asleep, awake, and restless.
- Tap the arrow in the bottom left to return to your sleep summary.
How does my tracker automatically detect sleep?
All of our wrist-based trackers automatically detect your sleep, meaning you just need to wear your tracker to bed. After you sync your tracker in the morning you'll see your sleep information on your dashboard. To track sleep with Fitbit One™, see How do I put my tracker in sleep mode?
Autodetection is based on your movement. When you haven’t moved in over an hour, algorithms assume that sleep has begun, which is confirmed by the length of time your movements are indicative of sleep behavior only (rolling over, etc). Morning movement tells your tracker that you’re awake. If you’re not moving but not asleep for long periods of time it’s possible for your tracker to falsely record sleep, in which case you can delete the sleep record from your dashboard.
Can I change my sleep goal?
For instructions on changing a sleep goal, choose a section below. Note that only time spent asleep counts towards your sleep goal, not time spent in bed awake.
- From the Fitbit app dashboard, tap the sleep tile. This is the tile that says "How did you sleep?" or, if you tracked sleep the night before, shows how many hours and minutes you slept.
- Tap the gear in the top right.
- Adjust your sleep goal and don't forget to save
- On the Fitbit app dashboard, tap the sleep tile. This is the tile that says "How did you sleep?" or, if you tracked sleep the night before, shows how many hours and minutes you slept.
- Tap the moon icon on the bottom.
- Adjust your sleep goal and tap Save.
Can I log a nap?
If your tracker automatically detects sleep, all naps at least an hour in length are saved in your sleep history. If you have a Fitbit One you must turn sleep mode on and off to record a nap.
What should I know about setting a sleep schedule?
To learn how your tracker can help you maintain a more consistent sleep pattern, see What should I know about setting a sleep schedule?
How do I set a silent alarm?
You can set and manage silent alarms in the Fitbit app. For more information, see How do I manage silent alarms?
How is sleep efficiency calculated?
We use the following equation to calculate your sleep efficiency: 100 * time asleep / (time asleep + time restless + time awoken during sleep)
The time it takes for you to actually fall asleep is not incorporated into this calculation. If you don't move all night it is possible to get 100% sleep efficiency even if it takes you 20 minutes to fall asleep. To see your sleep efficiency, go to the fitbit.com dashboard and click the Sleep tile > See More. Sleep efficiency isn't visible in the Fitbit apps.
