How Accurate is Fitbit Sleep Tracker

3 min

That is a very controversial question that how accurate is the Fitbit sleep tracker? Along with many other people, the company believes that these trackers provide the most accurate details about your sleep patterns and sleep stages.

There have been many different sleep trackers in the market before, but they have failed to provide any legitimate results. Due to which all of them have been discontinued. But surprisingly, Fitbit is still in the sleep tracking market and is providing some astonishing results.

Let us discuss more the accuracy of Fitbit according to experts and the company itself. So let’s get started.

Accuracy According to Fitbit Company

The company claims that the Fitbit provides almost near to accurate results. They conducted a research where they used Polysomnography and their Fitbit Sleep Trackers simultaneously. They concluded that the results shown by the Polysomnograph, which is the most legitimate way to track sleep, were nearly equal to the one the Fitbit sleep tracker showed.

They used 60 people and determined the different sleep stages such as light sleep, deep sleep, and REM. The findings showed that the adults sleep for 6 hours and 20 minutes, and 13% of it is deep sleep. And the teenagers had a sleep average of 6 hours and 45 minutes, out of which 17% was a deep sleep.

You can find many different research papers on Google to determine the sleep stages and patterns. I told you this just for an extra bit of information. But in the end, the point was that the Fitbit sleep tracker is not 100% accurate, and neither did the company claim it.

Accuracy According to Experts

The Experts believe that the Fitbit Sleep tracker is not suitable to determine the exact sleeping stages and timing. They say that the Fitbit only has a single Accelerometer that works according to the hands’ movement, and during sleep, we move our hands equally either we are in light sleep or deep sleep.

They think that Polysomnography is the only method by which we can track anyone’s sleep as they contain electrodes and other devices to measure the sleep stages accurately. The fitness trackers can’t do so, but at the same time, the results shown by Fitbit make them question their judgment.

Another thing that was worrisome for everyone was that these Sleep trackers are not a very healthy recommendation for people who have sleep disorders to worsen their conditions. Still, there has been no proof to this hypothesis. Some think that the Fitbit sleep tracker is good enough, and some think it is not, and this confusion will remain with us all the time.

Things affecting the Accuracy of Fitbit

There are a few things that might hinder the accuracy of the Fitbit sleep tracker. To get the most accurate sleep readings, you must wear them all day long, and all its sensors work correctly. But still, a few things might cause issues while trying to track the sleep stages.

Your sleeping position is the most common cause, due to which the Fitbit might have some difficulties in determining the exact sleep details. It is usually found in users who have bad sleeping posture as they sleep on one side and wake up on the other. It hinders the data being calculated by the Fitbit.

Another thing is that our human body works in different ways. Sometimes it needs more sleep, and sometimes less amount of sleep can also do the trick. The sleep trackers are not yet efficient to determine how much sleep a person needs, but if we look at the daily activities, we may measure it too accurately.

The last thing that can cause accuracy issues is the Algorithm used inside the watch to calculate the sleep stages and pattern. The company has stated that they have recorded thousands of sleeping patterns, after which they made it. But in the end, it is just a machine that can fail you at any time.


Now you know how accurate the Fitbit sleeping tracker is. Many people believe that these trackers are not accurate and can cause a person to have a bad sleeping habit. But as the company claims and as many people have reported, it provides almost accurate details and improves the sleep pattern.

You can buy a Fitbit watch if you want to see the average time you have slept. According to researchers conducted, an average young human being needs 7 to 9 hours of sleep to keep himself healthy and energetic.
