How to check your Fitbit sleep score

The Fitbit sleep score is a quick way to gauge your sleep quality. It is based on your heart rate, the time you spend awake or restless, and your sleep stages. The overall sleep score is a sum of individual scores for sleep duration, sleep quality, and restoration, for a total score of up to 100.

To check your Fitbit sleep score, follow these steps:

  • Wear your Fitbit device to bed and ensure that it has enough battery to last through the night.
  • In the morning, sync your Fitbit device. You can do this by swiping up from the clock face on most Fitbit devices to access your daily stats, including your most recent sleep session. On the Fitbit Sense 2 and Versa 4, swipe left or right from the clock face to find the Sleep tile.
  • To access more detailed sleep data, open the Fitbit app on your phone. From the \"Today\" tab, tap the \"Sleep Duration\" tile. Here, you will find your sleep score details, including your sleep duration, sleep quality, and restoration.
  • To review your sleep stats for previous days, tap the arrow icons next to the current day to navigate forward or backward. You can also use the week, month, or year tabs to access older data.
  • For a faster way to check your sleep data, you can add the Sleep tile to your watch.
  • If you have a Fitbit Premium subscription, you can access additional insights, including a detailed breakdown of your restoration score and analysis of your sleeping heart rate.

By regularly checking your Fitbit sleep score and understanding the different components, you can gain valuable insights into your sleep patterns and make informed decisions to improve your sleep quality.

The benefits of tracking your sleep

Sleep is an essential component of health, and its timing, duration, and quality are critical determinants of a person's overall health, playing a role in metabolic and emotional regulation, performance, and memory. The best way to know if you are getting enough sleep is to track it. Here are some benefits of tracking your sleep with a Fitbit device:

Understand your sleep patterns

By tracking your sleep, you can gain insights into your sleep patterns and identify any areas that need improvement. Fitbit's sleep feature estimates sleep stages by using a combination of movement and heart rate patterns. It also tracks the beat-to-beat changes in your heart rate, known as heart rate variability (HRV), to determine the transitions between light sleep, deep sleep, and REM sleep stages.

Improve your sleep habits

With the data provided by Fitbit, you can work on improving your overall sleep habits, heart health, and activity levels. Fitbit Premium offers tools and guided programs developed with sleep experts to help you build better daytime and nighttime habits for achieving deeper and longer sleep.

Monitor your sleep environment

Fitbit devices with a microphone, such as the Fitbit Sense or Fitbit Versa 3, can track noise levels and check for snoring throughout the night. This feature can help you identify any disturbances in your sleep environment that may impact your sleep quality.

Track your sleep duration and quality

Fitbit provides a daily sleep score that gives you a quick overview of your sleep quality. The score is based on your heart rate, the time spent awake or restless, and your sleep stages. By tracking your sleep duration and quality over time, you can identify patterns and make informed decisions about your sleep habits.

Enhance your overall health and well-being

Getting sufficient high-quality sleep is essential for your overall health and well-being. By tracking your sleep with Fitbit, you can make informed adjustments to your sleep habits, which can positively impact your energy levels, activity, mood, weight, and more. Additionally, sleep is important for draining the brain of toxins linked to Alzheimer's disease and for consolidating memories from the previous day.

How to improve your sleep score

Your Fitbit sleep score is a gauge of your sleep quality. It is based on your heart rate, the time you spend awake or restless, and your sleep stages. The overall sleep score is calculated by adding up your individual scores for time asleep, deep and REM sleep, and restoration, for a total score of up to 100.

  • Exercise earlier in the day or at least 3 to 4 hours before you sleep. Exercise is important for improving your overall heart health and activity levels, which can positively impact your sleep score.
  • Maintain a consistent sleep schedule. Keeping a regular sleep schedule can help regulate your body's internal clock, making it easier to fall asleep and wake up at consistent times.
  • Reduce your caffeine intake. Caffeine can impact your sleeping heart rate, so limiting your consumption to the morning can help improve your sleep score.
  • Wind down before sleep. Try incorporating relaxing activities into your bedtime routine, such as reading with reduced blue light, listening to light music, or drinking herbal tea. These activities can help you relax and prepare your body for sleep.
  • Use an eye mask. If you suspect that light is waking you up earlier than intended, consider using an eye mask to block out light and promote a longer, uninterrupted sleep.
  • Try sleep meditation. The Fitbit app offers sleep meditations that can help you fall asleep and improve your overall sleep quality.
  • Edit your sleep goal. If your sleep goal is set to 8 hours, consider adjusting it to 7 hours. This way, you are more likely to achieve your goal and earn a higher sleep score.
  • Monitor your sleeping heart rate. Your sleeping heart rate should ideally be lower than your resting heart rate. If it is higher, try incorporating breathing exercises or interval training to help lower your heart rate and improve your sleep restoration.

The limitations of the sleep score feature

The Fitbit sleep score feature has been described as a "novelty" by some users, who feel that it does not offer useful information. For example, some people have noticed discrepancies between their sleep scores and sleep duration, with higher scores being awarded for shorter sleep durations. This could be because the sleep score takes into account other factors such as sleep quality and restoration, but it is not clear to users how to view the scores for these individual components.

Additionally, the sleep score feature is not available on all Fitbit devices, and some older devices cannot support it. This has frustrated some users who have found that their average sleep time data has been replaced with the average sleep score.

The sleep score also relies on the detection of sleep stages, but this can be inaccurate. Factors such as how the tracker is worn or the user's sleeping position can prevent the device from recording this information. This may be particularly frustrating for fretful sleepers who are keen to understand their sleep patterns, as it could lead to more stress.

Another limitation is that the sleep score is based on the assumption that a higher score is indicative of better sleep quality. However, some users have pointed out that the amount of deep sleep and RHR (resting heart rate) has a larger impact on how they feel during the day, whereas these factors have a relatively low impact on the score.

Finally, to access a detailed breakdown of the sleep score, including the restoration score and sleeping heart rate, users must purchase a Fitbit Premium subscription.

  • Tapping on the Sleep duration tile (from the Today tab) or
  • Scrolling down to the snoozing moon icon (from the Today screen).
  • From here, you can view your Sleep Score, bedtime, wake time, and the amount of time spent in different sleep stages.
  • To see more detailed information, tap into any night's graph or sleep section.
  • You can now access vertical or horizontal bar graphs that showcase your sleep data for the week, month, three months, or even the year.
  • Additionally, you can toggle between viewing your Sleep Score, sleep schedule, sleep duration, and time in different sleep stages.
