Sleep tracking devices can be worn on the body or placed on a bedside table. They can be used to monitor sleep duration, quality, and phases. They can also help users recognize patterns in their sleep habits.
Accelerometers
Accelerometers are a standard method for sleep detection. They involve asking the user to record their time in bed, sleep onset, and waking-up time. Accelerometers can also be used in conjunction with sleep diary records to detect sleep episodes within the sleep period time window (SPT-window). This is the time window starting at sleep onset and ending when waking up after the last sleep episode of the night.
Microphones
Sleep tracking apps like SleepRoutine use microphones to detect respiration sound and measure sleep stage, efficiency, and latency.
Thermometers
Sleep trackers can also monitor body temperature, which can affect sleep quality.
Heart rate monitors
Sleep trackers with heart-rate monitoring capabilities can track the link between heart rate and sleep quality. Trackers like the Whoop 4.0 and the Oura Ring have been praised for their accuracy in this regard.
SpO2 trackers
Some sleep trackers monitor nightly blood oxygen saturation levels. Examples include the Garmin Vivosmart 4 and the Fitbit app.

Sleep quality: Trackers can detect interrupted sleep, tossing and turning, and sleep phases
Sleep trackers can be useful for helping you recognize patterns in your sleep habits. They can detect interrupted sleep, tossing and turning, and sleep phases. However, it's important to note that their accuracy may vary and they might not differentiate between sleep and wakefulness in people with insomnia.
Sleep trackers work by measuring body movement and sometimes heart rate data. They can estimate the phases of sleep by detecting changes in your pulse and oxygen saturation levels. For example, when you enter the REM stage, your pulse may increase, while it will be lower during light and deep sleep. However, these methods are not accurate indicators of brain activity and do not differentiate between sleep stages based on motion alone.
Some sleep trackers also incorporate environmental and lifestyle factors, such as light, temperature, caffeine intake, and stress levels, which can impact sleep quality. These devices often provide user-friendly graphs or reports to help you identify trends in your sleep patterns.
While sleep trackers can offer insights into your sleep habits, they should not be solely relied upon for sleep analysis. If you have concerns about your sleep quality, it is recommended to consult a health practitioner. Additionally, the data from sleep trackers could potentially impact your emotional state and concentration levels, so it is important to be mindful of how you interpret the information provided by these devices.
In summary, sleep trackers can detect interrupted sleep, tossing and turning, and provide estimates of sleep phases. However, their accuracy may vary, and they should be used as a tool to gain insights into your sleep habits rather than a definitive measure of sleep quality.

Sleep duration: Trackers can record when you fall asleep and when you wake up
Sleep tracking devices can record when you fall asleep and when you wake up. They do this by tracking your inactivity, or the time you are not moving. Sleep trackers can be worn on the wrist, clipped to a pillow, or placed on a bedside table. They can also be in the form of a smartphone app, which can be placed on a bedside table.
Sleep trackers can be useful for helping you recognize patterns in your sleep habits. For example, you might feel more energetic after sleeping from 11 pm to 7 am than from 10 pm to 6 am. Or you might find that you sleep better when your bedroom is cooler or on days you exercise.
Sleep trackers can also detect interrupted sleep, letting you know when you toss and turn or wake up during the night. However, it is important to note that sleep trackers only measure movement and do not differentiate sleep stages based on motion alone. As a result, they may not be as accurate for people with insomnia who tend to remain very still while trying to fall asleep.
Some sleep trackers also measure heart rate, which fluctuates during different sleep stages. Watches that incorporate heart rate data tend to be slightly more accurate when measuring sleep duration. Additionally, some sleep trackers use microphones to capture noise or measure respiration, detecting snoring, sleep apnea, and how often you wake up. Others may have thermometers to measure the temperature of the room, which can impact sleep quality.

Sleep patterns: Trackers can help you recognise patterns in your sleep habits
Sleep tracking devices can help you recognise patterns in your sleep habits. They can be a useful tool to gain insight into your sleep routine and quality. For example, you might discover that you feel more energetic after sleeping from 11 pm to 7 am than from 10 pm to 6 am. Additionally, you may find that your sleep is better on days you exercise or when your bedroom is cooler. Some trackers even allow you to input lifestyle factors, such as caffeine intake, meal times, and stress levels, which can further help you identify patterns and factors influencing your sleep.
Sleep trackers come in various forms, including wearable smartwatches, wristbands, rings, headbands, pillow or bedside table devices, and smartphone apps. Most sleep trackers measure sleep quantity and quality by using accelerometers, or small motion detectors, to analyse body movement during sleep. They can also detect interrupted sleep by identifying periods of tossing and turning or waking up. However, it is important to note that movement alone may not accurately differentiate between sleep stages, as people move frequently during all stages of sleep.
To address this limitation, some trackers incorporate additional data, such as heart rate, oxygen saturation, or pulse, which can provide stronger indications of sleep stages. Watches that include heart rate data tend to be more accurate in measuring sleep duration because heart rate fluctuates during different sleep stages. Additionally, some trackers use microphones to capture noise or body movements, detect snoring, sleep apnea, and sleep quality. Others may include thermometers to measure room temperature, which can impact sleep quality.
While sleep trackers can provide valuable insights, it is important to interpret the data with caution. Studies have shown that sleep trackers may underestimate the amount of deep sleep obtained and may not accurately differentiate sleep stages. Polysomnography tests, which analyse brain wave patterns, remain the most accurate method for determining sleep stages. Additionally, the impact of sleep data on mental health is a concern, as individuals who experience poor sleep may be more likely to use sleep trackers, potentially worsening existing mental health issues.

Sleep tracking accuracy: Trackers may not differentiate sleep stages accurately
Sleep tracking devices are worn on the wrist and make estimates of nightly sleep by measuring body movement and sometimes heart rate data. However, as we move during all stages of sleep, movement provides few clues about what sleep stage we're in. Many sleep devices also fail to differentiate one stage of sleep from another based on motion alone.
Polysomnography tests are the most accurate as they track a person's brain waves, heart rate, breathing, blood oxygen levels, and body and eye movements during sleep through electrodes attached to the skin and scalp. Analysing brain wave patterns is the only definitive way of knowing whether someone is awake or asleep, and to know what stage of sleep they're in.
Research has found that compared to polysomnography tests, sleep trackers are only accurate 78% of the time when identifying sleep versus wakefulness. This accuracy drops to around 38% when estimating how long it took participants to fall asleep.
Sleep devices also underperform in people with insomnia. People with insomnia tend to remain very still in bed in an attempt to fall asleep. But as sleep trackers only measure movement, one study found watches were unable to differentiate sleep from wakefulness in people with insomnia.
While sleep tracking devices can be useful for helping you recognize patterns in your sleep habits, it's important to take the numbers with a grain of salt. If you have any concerns about the quality of your sleep, it's a good idea to talk to a health practitioner.
