Fit Charge 3 Registered 2000 Steps While Sleeping?

Fitbit is the all-time in the business at tracking sleep from the wrist, and information technology's now even more unproblematic and effective with the addition of Slumber Score.

Those with Fitbit trackers accept long been able to access Slumber Stages graphs and breakdowns, but Sleep Score condenses all the information from your dark'south sleep and spits it out equally a circular figure.

You'll find Sleep Score on Fitbit Versa 2, Fitbit Charge 4 and Fitbit Inspire 60 minutes.

If yous're new to the Fitbit app or Sleep Score, though, you might take a few questions. Below, we'll explicate what a good score is, how you can improve it and more features that could come up presently.

Does your Fitbit accept Sleep Score?

Sleep Score is available through any Fitbit with a center rate monitor, which includes the Accuse 4, Versa 2, Versa, Versa Lite and Ionic.

However, if y'all want the total hit from Fitbit's array of tracked metrics, yous'll need to be a Fitbit Premium member, which lets you also proceeds insights into your Sleeping Heart Rate and Restlessness.

This gives insights into Sleeping Heart Rate and Restlessness, which and then both are added to your Fitbit Sleep Score.

What is a good Sleep Score? How is it calculated?

There's been a lot of change to Fitbit's sleep tracking with the introduction of Sleep Score, but information technology's all even so very intuitive - and this is helped by the tin can't-miss score correct in the middle of sleep section.

"Some feedback we got was to simplify it into a single number then people could come up accept a simple metric," said Dr Conor Heneghan, atomic number 82 sleep research scientist at Fitbit.

So, any score above 80 would exist considered a 'Practiced' slumber, something in the 70s would be 'Fair', and anything below that is… not great. Fitbit says that almost users become a score between 72 to 83.

How is this Sleep Score number actually worked out, though?

Well, the number is made by combining three other scores. The kickoff is Sleep Duration, which looks at your length of sleep and compares to your average bedtimes and wake-upwardly goals. Information technology besides compares your sleep elapsing confronting the average score for your historic period/gender bracket.

Sleep Depth, the second score, is calculated from how much time you spend in deep sleep and REM within your benchmarks.

The third score, referred to every bit Revitalization during the beta, is a piffling more interesting. Here, Fitbit is using data for breathing disturbances and comparing your heart rate during sleep to wake hours.

These checks for animate disturbances currently don't accept whatever information from the Estimated Oxygen Variation graph, which separately harnesses the SpO2 sensor, but at that place's a possibility nosotros see this factored into Sleep Score figures in the future, as we detail farther in the section below.

More than features coming soon to Sleep Score?

When we tried out the Sleep Score beta, it also featured something called the Restoration alphabetize. It'due south hither where Fitbit indicated it will look for signs of asthma, allergies and even sleep apnea.

Sleep apnea, where breathing stops and starts during sleep, causes blood oxygen levels to fluctuate.

Fitbit is yet yet to receive FDA clearance, and so information technology can't actually say any tracked patterns are indicative of asthma, sleep apnea or other conditions. What information technology does instead - at least for now - is just report on big fluctuations.

In the app, under the 'Learn More' section of the Estimated Oxygen Variation graph, this is clarified farther.

"Your Fitbit tin't measure out the blood'south exact oxygen saturation level, but it can observe major changes. Seeing big changes is a inkling that you may be experiencing breathing disturbances during sleep," Fitbit says.

And then, when could we see the current estimate transform into a more accurate metric that tin feed into Fitbit Sleep Score?

"Nosotros're continuing our clinical trials to collect the data to support that last application," said Heneghan back in August, discussing the company's work with the FDA. "We're nevertheless at the early stages of testing."

Yous can bet that when the company does receive clearance - something that'southward potentially being held up past the Google takeover deal - Sleep Score will ameliorate even further.
