Sleep Trackers: Do They Diagnose Sleep Disorders?

Sleep tracking apps and devices have become increasingly popular, with many people turning to technology to help them understand their sleep patterns and improve their sleep quality. While these apps and devices can provide interesting insights and help users identify trends in their sleep habits, they have their limitations and should not be relied upon for medical advice or diagnosis. So, can you see sleep disorders in sleep tracker apps?

Sleep trackers can help identify sleep disorders

Sleep trackers can be a great way to identify sleep disorders. They can help you keep track of your sleep patterns, duration, and quality. While they do not measure sleep directly, they often estimate sleep by measuring inactivity. Sleep tracking devices can record when you fall asleep, when you wake up, and how often you wake up during the night. They can also detect interrupted sleep, letting you know when you're tossing and turning.

Some sleep trackers can also measure your heart rate, respiratory rate, and body temperature. This data can be useful in identifying trends in your sleep habits and recognizing patterns. For example, you might discover that you sleep better when your bedroom is cooler or on days you exercise. You can also use the data to identify changes in trends, such as if your sleep time changed abruptly, and then look for corresponding changes in your stress levels, environment, or daytime habits.

Sleep tracking apps can also be used to set goals and create a customized sleep schedule. You can use the data to experiment with different evening routines and see if your sleep data improves. Some apps also offer soothing sounds or strategies to help you relax and fall asleep.

It is important to note that sleep trackers cannot diagnose or treat sleep disorders. If you have concerns about the quality of your sleep, it is recommended to talk to a health practitioner. Sleep trackers should be used to gather additional information and not as a replacement for medical advice or a clinical sleep study.

Sleep trackers cannot diagnose sleep disorders

Sleep trackers are not capable of diagnosing sleep disorders. While they can collect a lot of information about your sleep habits, they don't measure sleep directly. Instead, they often measure inactivity as a surrogate for estimating sleep. Most sleep-tracking devices make some guesstimates as to how much you're actually sleeping. They are not designed to diagnose sleep disorders or other health problems.

Sleep trackers are typically worn on the wrist, and they make their estimates of nightly sleep by measuring body movement and sometimes heart rate data. As we move frequently 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. The algorithms used by companies to make predictions about sleep are unknown, making it difficult for scientists to identify whether the assumptions made by the sleep devices are valid.

Some trackers may give the impression that they are able to diagnose a medical condition when they don't have the data (or FDA approval) to back up those claims. Sleep trackers must fit into your life. Think about how a prospective tracker might fit into your digital ecosystem, how easy it is for you to use, and how comfortable it is to wear during sleep.

For exact data about your sleep habits, you would have to do a medical sleep study, which monitors brain waves to analyze the stages of sleep you cycle through during the night. Such studies are helpful for diagnosing conditions like sleep apnea and other sleep disorders. Sleep labs use polysomnography, which is considered the gold standard in measuring sleep. These sleep studies monitor brain wave activity, eye movement, muscle tension, movement, and breathing for accurate measurement of the four stages of sleep.

While sleep trackers can be useful for helping you recognize patterns in your sleep habits, they could also cause unwanted anxiety. For example, people who experience poor sleep may be more likely to use sleep-tracking devices, which could be a concern as it may potentially worsen mental health issues.

Sleep trackers can help you set sleep goals

Sleep trackers can be a great way to set sleep goals and improve your sleep quality. They can help you establish a bedtime routine, which is vital for improving your sleep. Many sleep trackers can measure your heart rate, skin temperature, blood oxygen levels, and time spent in each sleep phase. They can also detect interrupted sleep, letting you know when you wake up or move around during the night.

Many sleep trackers also offer built-in coaching features that can help you work towards your sleep goals. These features can include suggestions for improving your sleep hygiene, such as establishing a pre-sleep routine or reducing caffeine intake. Some sleep trackers even offer personalized sleep tips based on your data. For example, the Whoop sleep tracker calculates how much sleep you need based on your physical and mental activity levels. It then uses this information to suggest optimal sleep times.

In addition to helping you set sleep goals, sleep trackers can also help you stick to them. Many sleep trackers allow you to set sleep schedules and bedtime reminders. Some even have features like Wind Down, which helps you establish a bedtime routine by reducing distractions and simplifying your Lock Screen.

It's important to remember that sleep trackers are not a substitute for medical advice. If you have concerns about a sleep disorder or your sleep quality, it's best to consult a healthcare professional. Additionally, sleep tracking is not for everyone. Some people may find that it increases their anxiety about insomnia or sleep quality. As such, it's important to listen to your body and use sleep tracking in a way that works for you.

Sleep trackers can help you experiment with your sleep

Sleep trackers can be a great way to experiment with your sleep and gain valuable insights into your sleep patterns and quality. While they don't directly measure sleep, they can estimate sleep by tracking inactivity and movement during sleep. This allows you to reflect on your sleep habits and make informed decisions to optimize your sleep.

For example, sleep trackers can help you identify trends and patterns in your sleep. You can track your sleep duration, sleep quality, and sleep phases. If you notice that you consistently sleep better when your bedroom is cooler, you can make a conscious effort to adjust the temperature before bed. Similarly, if you find that caffeine after lunchtime disrupts your sleep, you can experiment with limiting your caffeine intake to earlier in the day.

Sleep trackers also allow you to set personalized sleep schedules and goals. You can experiment with different bedtimes and wake-up times to see what works best for you. For instance, you might try going to bed an hour earlier for a week and observe how it affects your energy levels and productivity throughout the day.

Additionally, some sleep trackers provide tips and strategies to improve your sleep. They may suggest evening routines, bedtime habits, or changes to your sleep environment. By following these recommendations, you can experiment with different approaches to enhance your sleep quality.

It's important to remember that sleep trackers should not be used as a substitute for medical advice or a clinical sleep study. While they can provide valuable insights, they are not yet capable of diagnosing or treating sleep disorders. If you have concerns about your sleep, it's always best to consult a healthcare professional.

Sleep trackers can be inaccurate

Secondly, commercial sleep trackers often supply extra data like heart rate and oxygen levels, but the primary limiting factor is the lack of studies that corroborate their accuracy compared to actigraphy or polysomnography (PSG). PSG is used by doctors to diagnose sleep disorders, but the tests are expensive and require specialist evaluation.

Thirdly, the accuracy of commercial sleep trackers compared to actigraphy means that wearers can expect data that is similar to some research-grade sleep-tracking devices. However, more research is needed to verify the reliability of wearables, especially as the technology is constantly evolving and improving.

Finally, the accuracy of sleep trackers varies between different devices and individuals. For example, results can differ between the Apple Watch and Autosleep, and the Ultrahuman Ring Air has been praised for its accuracy by one source while another found it less accurate than the Apple Watch. One user on Reddit noted that the Apple Watch's sleep algorithm barely worked for them, with their deep sleep values going undetected and being misclassified as light sleep.

Therefore, while sleep trackers can be a useful tool for monitoring sleep habits and spotting trends, it's important to take the data with a grain of salt and consult a health practitioner if you have concerns about your sleep quality.
