Are sleep trackers accurate?

Last Updated on January 10, 2022

Everyone has those days when they wake up refreshed and the ones they’ve barely slept at all. Sleep trackers can give valuable insight into what separates the good nights from the bad nights. It shows you how much quality sleep you’re getting. This information can be used to improve your sleep.

While lab-based sleep tests usually track patterns through brain activity, these devices rely on sensors to detect other physical signs, like heart rate and body movement. Wearable devices measure data all night long, whereas other trackers may rest on the mattress, under the mattress or next to the bed to collect information.

If you use a sleep tracker, it will monitor your heart rate and movement and show you the results on your phone or desktop. There are different types of sleep devices, most options are worn on the wrist such as smartwatches and wrist bands, but there are other available options like headphones, headbands and under mattress items. 

With today’s market being flooded with cheap low-quality products, you cannot help but wonder are sleep trackers accurate in what they do?

If you want to measure your sleep efficiency without sleeping in a lab, sleep trackers are the most accurate way to do so. You improve the accuracy and import data from other health and fitness apps when you edit your data. Keep in mind that sleep trackers should be used with good sleep hygiene in order to get the most out of them.

Some people have trouble sleeping because of their sleep trackers. If you suffer from a sleep disorder where a patient becomes preoccupied with their sleep efficiency, then you should consider seeking professional help.

These devices features can vary, but most have overall common capabilities like sleep duration, quality, phases, environmental and lifestyle factors. 

By duration, we mean recording when you fall asleep at night and when you stir in the morning. By sleep quality, we mean the detection of interrupted sleep, so you can see why you’ve been tossing and turning or waking during the night.

Sleep phases are another capability of trackers that detect the phases of your sleep and time your alarm to go off during a period when you’re sleeping less deeply.

We can also find devices that record the amount of light or temperature in your bedroom. Some devices prompt you to enter information about activities that can affect sleep, such as how much caffeine you’ve had, when you’ve eaten or whether your stress level is high. This way, the expertise will be more in debt, making it more accurate and informative. If you don’t know where to start, take a look at our ‘Top 10 Sleep Trackers.’

Do sleep trackers work?

Overall, it’s essential to understand that the data collected by wearable sleep trackers are very indirect measurements of your sleep. 

That’s why you might want to be particularly wary of the more complex metrics, such as sleep quality, sleep scores or readiness ratings, as well as the time spent in various stages of sleep, isn’t likely to be very accurate, either.

However, most wearable devices are pretty reliable at measuring when you went to sleep, when you woke up, and the total time you spent asleep. For some individuals, these metrics might not sound all that flashy, but truth be told, this information can be very beneficial for identifying factors that lead to poor sleep.

In general, people don’t need a sleep study to understand why they’re not getting quality sleep. The majority of individuals experience bad sleep due to poor sleep habits and bad sleep hygiene, which, when improved, can positively relate to the quality of your rest.

Sleep trackers are equipped with tools and features which can help you make adjustments to wake up well-rested and refreshed every morning. They monitor things like sleep duration, quality, heart rate, blood oxygen level, etc.
