![]() If you want to maximize the efficiency of your Fitbit tracker it is vital that it is put into sleep mode before you hit the bed. Before you think about it, yes we are aware off how – not good – it is but believe me when I say this: that just updating the OS can save you from 75% of the problems. Your Fitbit’s OS VersionĪ lot of your Fitbit problems can be solved with a simple solution of just updating the OS of your Fitbit smartwatch. So if by chance you’ll be on the Fitbit device released long ago, fully expect the disparity between results. However, even more important thing is that there will be difference between the quality of the latest generation to the previous one. Which also means that the current generation of Fitbit devices will be more closer to end of their cycle than before. We are moving towards the year 2024 which means it’s just matter of time till we hear about the next Fitbit Versa 5and Fitbit Sense 3. Meaning it could be wrong about your sleep and heart rate and still be very very confident about it. But here is the catch: Just like sleep tracking even heart rate monitoring on Fitbit trackers is not 100% accurate. Fitbit uses both the movement and HRV (Heart Rate Variability) to decide which phase you are currently in. Your HeartĪnother factor which plays huge role is your heart rate. Then it doesn’t matter if your reason of non-motion is because you are reading a book very quietly or you are actually sleeping. Because the basic principal states that if your Fitbit will feel you are not in motion, then it will declare you asleep. Your MotionĪ very important part of Fitbit’s sleep tracking is how well it can tell you are in motion or not. However, there is still some thing we need to know: What are those factors that makes the Fitbit model moot and if there is a chance we can play God here and use it for our good. Factors That Affects Fitbit Sleep Tracking Accuracy?īy now we have established the fact that Fitbit’s sleep tracking model is not accurate and you shouldn’t depend on it with your life. On the other hand, the Fitbit sometimes thought people were in light sleep when they weren’t actually. It missed about half of the deep sleep and around a third of the REM sleep. The Fitbit often didn’t catch as much deep sleep and rapid eye movement (REM) sleep as the polysomnography did. But when they compared the Fitbit to the polysomnography results, they saw some big differences. The researchers found that the Fitbit was pretty similar to the actigraph in many ways. This test checks lots of things while you sleep, like what your brain is doing, how your eyes move, how your muscles work, and your heart rhythm. However, they also used a more complicated test called polysomnography. It was designed to check their sleep in one night using the Fitbit and the actigraph. So, there was this study with 42 people conducted at Monash University who also had trouble sleeping. If it wasn’t please keep reading! Issue With Inaccurate Results From Fitbit Sleep Tracking So if you are question was just: Is Fitbit Sleep Tracking Accurate? You have your answer. When in reality or in the Lab in order to accurately tell the correct stages, brain waves are measured, which a Fitbit tracker can never do. Fitbit presents to you Sleeping Stages using just two sensors like we have discussed above. Over the years many researches have spent thousands of hours in lab testing new Fitbit models against the clinical medical equipment and every time a same theme has been painted on results: Fluctuations Within Fitbit’s Sleep Tracking Model. The sleep score that you see on your Fitbit tracker is not what it seems to present itself. But does that simplicity translates into accuracy? ![]() In theory it feels very simple and believe me even in practice it is, and it is one of the elegant thing about it: Simplicity. Second is the PPG method deployed using greenlightwhich is employed to find the heart rate of a person. However, just for the sake of argument right now, you should know this:įitbit tracks sleep using two sensors, the first is accelerometer which gives your tracker information regarding your motion. If you want to, you can see it for yourself. We have covered the working of Fitbit Sleep Mode in details here. Or at least a place where accuracy shouldn’t be questioned. Meaning that Fitbit should’ve reached the primal status by now. But this is not taken from yesterday, it has been a while. When asked about the Fitbit’s greater vision this is what the lead scientist Conor Heneghan had to say. “We are researching ways in which Fitbit can help assess conditions such as cardiovascular disease, sleep problems, stress, pre-diabetes and diabetes, and help users with interventions for chronic conditions.” Fitbit Lead Research Scientist Conor Heneghan ![]()
