What is a sleep tracker?

Last Updated on January 10, 2022

Everyone has those days on which they wake up feeling refreshed, but they also have those on which it feels they’ve barely slept at all. It may not be obvious why some nights go well and others don’t, but sleep trackers can provide useful insights into which factors contribute most to successful sleeping patterns.

They aid you in monitoring your sleep patterns for a clearer picture of how much quality sleep you’re getting each and every night. ANd set information can be used to improve your sleep experience.

What is a sleep tracker?

They use various sensors to measure different aspects of sleep quality, like heart rate and body movement. Wearable devices typically remain on the sleeper throughout the night and measure their sleeping experience. At the same time, others may be placed inside mattresses, underneath mattresses, or near beds (smartphones – apps) for collecting information without being noticed by the people sleeping in bed.

Most products collect this data from devices such as smartwatches, fitness bands, rings and other options. They then run these numbers through their own proprietary software to calculate and present the results of your sleep cycle, show you how long you’ve slept for in each sleep stage, as well as how many times you woke up during the night.

However, in order to find the best sleep tracker on the market today, you have to know exactly what is a sleep tracker and how does it work. So let’s get started!

What is a sleep tracker and how does it work?

If you use a sleep tracker, it will monitor your heart rate and movement and show you the results on your phone or desktop. Most options are worn on the wrist (smartwatches & wrist bands), but there are other types of sleep trackers such as headphones, makes, headbands and under mattress items. 

They can detect your sleep cycles, how often you wake up, how long you were awake for, and how long it takes you to fall asleep. There are three stages to a person’s sleep: light, slow-wave brain activity and deep sleep. A sleep tracker will evaluate each night’s sleep, breaking it down into easy to understand graphs and percentages and marking you an overall score for your night’s rest.

The higher your sleep efficiency, the better quality of your rest. Several activities, including fitness, stress levels and Sp02 levels, which can detect sleep apnea, are tracked by some sleep trackers. You can sync your sleep tracker with your phone to closely monitor your sleep cycle and activity.

How can you clean a sleep tracker?

If you follow the manufacturer’s instructions, you can clean your sleep tracker with ease. Some items have covers that can be washed, while others can be wiped down with a damp cloth or cleaned with rubbing alcohol. You’ll be able to avoid damage to the sensors if you strictly follow the steps provided by the manufacturer.

How do smartwatches track sleep?

A smartwatch tracks sleep by using various internal sensors to collect information and interpret the data through an algorithm. However, some models may use additional external hardware such as heart rate monitors for added accuracy. Smartwatches tend to be less accurate at measuring sleep than dedicated wearables designed solely for monitoring sleep patterns, but that doesn’t mean they will get the job done.

More advanced options often collect other pertinent data, including respiration and snoring. Some can even detect room temperatures, noise levels, and additional factors that could impact the quality of your sleep.

Bottom Line

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

We hope we were able to answer the how and why when it comes down to ‘What is a sleep tracker and how does it work?’, and now it’s our turn to hear from you if any questions regarding the subject were left unanswered.
