Sleep plays a vital role in our overall health and wellbeing. Our brains and bodies need sleep to function properly, recharge, and repair damage. But sleep can be elusive for a lot of people.
A lot of factors can affect our ability to get a good night’s sleep, including stress, noise, light exposure, and even the temperature of our bedroom. So how does a fitness tracker like the Fitbit help us track our sleep?
In this blog post, we’ll take a look at how the Fitbit tracks sleep and what kinds of data it collects. We’ll also explore some tips for getting better quality sleep using your Fitbit.
A good night’s sleep is essential for health but it can be difficult to get the recommended 7 to 8 hours of sleep. Fortunately, wearable devices like Fitbits can now track sleep patterns and provide valuable insights into sleep quality. But how does a Fitbit track sleep?
The sleep feature of Fitbit is quite accurate and it utilizes a combination of your movement and heart-rate patterns to estimate the sleep stages. When you don’t move for about an hour, your Fitbit device will automatically assume that you are sleeping. On the contrary, Fitbit devices also track additional data tracking time of moments that indicate sleep behavior, etc.
Another thing to notice is that the Fitbit devices monitor beat-to-beat changes in your heart rate. This phenomenon is known as Heart Rate Variability. The numbers depend as you transition between the stages of sleep, for instance, you can be in light sleep, deep sleep, and REM sleep stages. In the morning, when you sync your device, Fitbit uses movement and heart rate patterns to estimate sleep cycles.
All this data is displayed on the app so you can get an overview of your sleep habits. The app also offers suggestions on how to improve your sleep quality. For example, it might suggest going to bed earlier if it notices that you’re not getting enough deep sleep. Overall, the sleep feature of Fitbit is quite accurate and useful for tracking your sleep habits.
So if you’re looking for a way to get a better idea of how well you’re sleeping, a Fitbit might be a good investment. And who knows? Once you start tracking your sleep, you might be motivated to make some changes to help improve your sleep quality.
By understanding how Fitbits tracks sleep, we can better interpret the data they provide and make necessary changes to our lifestyles in order to get a better night’s rest.
How does Fitbit know when you’re in REM sleep?
Your heart rate changes while you sleep. It’s lower when you’re in deep sleep and higher when you’re in REM sleep. Fitbit uses heart rate variability (HRV) to estimate how much time you spend in each stage of sleep. HRV is the beat-to-beat changes in your heart rate.
To get a detailed breakdown of your sleep stages, wear your device to bed and enable REM sleep detection in the app. REM sleep is light sleep that happens when you dream. Usually, you have more REM sleep later in the night as you cycle through light and deep sleep stages. Most people need about 7-8 hours of sleep a day. During this time, they typically have 1-2 hours of REM sleep.
