Sleep Tracking Apps: Effective Or Just A Fad?

Sleep-tracking apps have become increasingly popular, with many people wanting to understand their sleep patterns and improve their sleep quality. These apps claim to help you understand when you fall asleep and wake up, as well as what happens in between. While they can collect a lot of information about your sleep habits, they don't directly measure sleep. Instead, they often estimate sleep by measuring inactivity and restlessness. Sleep-tracking apps can be a great way to identify patterns and make lifestyle changes to optimise your sleep, but it's important to remember that they are not a replacement for medical advice or a clinical sleep study.

Limitations of sleep tracking apps

Sleep tracking apps have gained popularity due to their convenience, affordability, and ease of use. However, there are several limitations and challenges associated with their use. Firstly, most sleep tracking apps do not directly measure sleep. Instead, they estimate sleep by tracking periods of inactivity and assuming that these periods correspond to sleep. This can lead to inaccuracies, especially if the user is not completely still during sleep or if there is interference from a partner or pet in the bed.

Additionally, while some apps use the phone's microphone to track sleep, this method may not be accurate in detecting the various stages of sleep, such as REM sleep, deep sleep, and light sleep. These apps rely on assumptions and algorithms to determine sleep patterns, which may not always be reliable. To accurately identify the different stages of sleep, more specialized equipment that measures brain waves, such as polysomnograph equipment, is required.

Another limitation of sleep tracking apps is the lack of empirical evidence supporting their claims. Many apps have not undergone rigorous validation studies, and the evidence they provide may have significant methodological limitations. For example, some studies may lack control groups or use unvalidated surveys, making it difficult to determine the true effectiveness of the app. Furthermore, there are data privacy concerns surrounding sleep tracking apps. Some apps share sensitive user data with business and marketing partners without the user's knowledge or explicit consent, as most users do not read the privacy policies before accepting them.

While sleep tracking apps can provide insights into sleep patterns and help raise awareness about sleep conditions, they should not be solely relied upon for diagnosing sleep disorders. If users have concerns about their sleep quality or suspect a sleep disorder, it is recommended to consult a healthcare professional or consider a medical sleep study for more accurate and comprehensive evaluation.

How sleep tracking apps work

Sleep-tracking apps are designed to help you understand your sleeping patterns. They can help you identify when you cross the threshold between waking and sleeping, and what happens in between. They can also help you understand when you enter the various stages of sleep, from light sleep to deep sleep, and the REM stage.

There are two main types of sleep trackers: wearable and non-wearable devices. Wearable trackers are available as headbands, wristwatches, bracelets, rings, or chest straps. Non-wearable trackers come in the form of phone apps and other bedside devices or those that you place under your bedsheet or pillow. Some apps require a subscription to unlock the more advanced features.

Smartphone sleep apps claim to measure your body’s movements using the phone’s accelerometer to track restlessness during the night. You can put your phone facedown next to you while sleeping and, in the morning, the app will provide you with a report of how many times you woke up and the times during the night you were active. However, it’s important to remember that these apps can’t truly identify when you’re sleeping or awake.

Wearable trackers, on the other hand, may be more accurate than apps as they reduce the chance that movement by a pet or bedmate is registered. They use built-in accelerometers and software to track your sleep patterns over time.

While sleep trackers can collect a lot of information about your sleep habits, they don’t measure sleep directly. Instead, they often measure inactivity as a way to estimate sleep. Most sleep tracking devices make some guesstimate as to how much you’re actually sleeping. For exact data about your sleep habits, you would need to do a medical sleep study, which monitors brain waves to analyse the stages of sleep.

Sleep-tracking apps are best for people who are casually looking for clues as to how they might sleep better. If you think you might have a sleep disorder, these apps are not a substitute for medical advice. However, you can share results from a sleep app with your healthcare provider and work to develop a plan for better sleep.

Sleep tracking devices vs. apps

Sleep tracking devices and apps have become increasingly popular in recent years, with many people wanting to gain insight into their sleep patterns and improve their sleep quality. While both options are widely available, there are some key differences between the two.

Sleep tracking devices typically take the form of wearables, such as smartwatches, fitness trackers, or rings, that you can strap to your wrist. Some devices can also be clipped to your pillow or pyjamas, placed under your mattress, or kept on your bedside table. These devices often use built-in accelerometers and software to track your sleep patterns, including sleep duration and quality. They can detect interrupted sleep, measure heart rate and blood oxygen saturation, and track your respiration and restlessness. Devices like the Apple Watch also offer bedtime routine features and gentle alarms in the morning. While these devices provide a wealth of data, their accuracy can vary, and it's important to take the numbers with a grain of salt.

On the other hand, sleep tracking apps are usually more accessible and inexpensive, making them appealing to a wider range of users. These apps often use the smartphone's microphone or speakers to track sleep through sonar technology. They send silent signals into the sleep environment, and the reflected sound waves are interpreted by algorithms to measure breathing rate and body movement. Apps like Sleep.com claim to provide an accurate picture of sleep patterns without the need for wearables. However, the accuracy of these apps has been questioned, and they may not be able to distinguish between your sleep and that of a bed partner or pet. Additionally, some apps allow you to input lifestyle factors, such as caffeine intake or stress levels, to help identify patterns affecting your sleep.

Both sleep tracking devices and apps have their advantages and limitations. Devices might be more accurate due to direct skin contact, but they can be more expensive and may not suit those who find wearables uncomfortable. Apps are convenient and affordable, but their accuracy can be impacted by external factors and the specific technology used. Ultimately, the choice between a sleep tracking device and an app depends on individual preferences, budget, and the level of insight desired.

Sleep tracking apps and insomnia

Sleep tracking apps are designed to help users understand their sleep patterns and improve their sleep quality. These apps use various methods to track sleep, including sound analysis, heart rate monitoring, and movement detection. While some apps simply track the duration and quality of sleep, others offer additional features such as soothing sounds or strategies to aid sleep.

The SleepScore app, for example, uses sonar technology to assess movement and breathing rate, providing an accurate picture of sleep patterns. Sleep Cycle, on the other hand, uses sound analysis to identify sleep states, although it can be prone to errors if other sounds are present in the room. Other apps, like Sleep Reset, offer personalized recommendations and one-on-one coaching to help users improve their sleep.

While sleep tracking apps can provide valuable insights, it's important to note that they are not always accurate. Some doctors and sleep specialists caution that tracking sleep too closely can increase anxiety, especially for those with insomnia or sleep anxiety. Sleep tracking apps should be used as a tool to gather information about your sleep habits, but they should not replace medical advice or a clinical sleep study. If you suspect you have a sleep disorder, it is important to consult a doctor or specialist.

Additionally, it is worth considering how a sleep tracker might fit into your digital ecosystem and daily routine. For example, some trackers require a power outlet, while others need to be worn on the body or placed under the mattress. It is also important to evaluate the accuracy of the data provided by these apps, as they may not always correctly distinguish between periods of wakefulness and light sleep.

Sleep tracking apps and migraines

Sleep tracking apps are designed to help users better understand their sleeping patterns. They can be used to track sleep cycles, the number of times a user wakes up, and the times during the night when the user is active. However, it is important to note that these apps cannot truly identify when a user is sleeping or awake.

For migraine sufferers, poor sleep can be a trigger for headaches and impact migraine severity and frequency. Sleep tracking apps can be a useful tool to help identify patterns and triggers for migraines. By tracking sleep patterns, migraine sufferers can gain insights into how their sleep may be contributing to their migraines.

There are several migraine-specific apps available that offer features such as headache and trigger tracking, sleep tracking, and community connections with other migraine sufferers. For example, Migraine Buddy helps users track, understand, and prevent migraine attacks by offering a questionnaire to identify triggers and a diagram to note pain locations. It also includes a sleep tracker that correlates sleeping patterns with migraine attacks.

Other apps, such as Juva, offer clinician-developed biofeedback sessions to help reduce migraine symptoms and improve sleep quality. White Noise Lite is another app that aims to improve sleep quality by providing calming sounds at bedtime. While these apps can be beneficial, it is important to note that they should not replace any prescribed treatments or sleep aids.

In addition to migraine-specific apps, there are also general sleep tracking apps that can be useful for migraine sufferers. For example, the Sleep.com app uses sonar technology to track sleep patterns through a user's smartphone speakers and microphone, without the need for wearables. This app can provide insights into sleep patterns that may be triggering migraines.
