Struggling to get quality sleep? Sleep tracking can help by identifying patterns, pinpointing disruptions, and offering insights to improve your rest. In this article, we'll explore the benefits of sleep tracking, how it works, and how it can help you sleep better.
While sleep medications may offer short-term relief, they often have ‘unwanted' side effects. Luckily, there are natural ways to improve sleep. For instance, you can create a relaxing bedtime routine, optimize your sleep environment, or make healthier lifestyle choices. That said, the first step you need to take to improve your sleep quality is to understand your sleep patterns and to work out the causes of insomnia.
And that's where sleep trackers come in. These devices use advanced techs to monitor your sleep and provide useful insights, helping you make informed changes for better rest. This article will help you explore how sleep tracking works, its benefits, potential limitations, and more.
What is Sleep Tracking?
Sleep tracking involves monitoring sleep patterns to gain insights into sleep duration, quality, and disturbances.
Sleep tracking is done using wearable devices, smartphone apps, or specialized medical equipment. By collecting and analyzing sleep data, sleep tracking helps identify irregularities that may signal a potential sleep disorder.
How Does A Sleep Tracker Work?
Sleep tracker devices use various sensors and algorithms to monitor different aspects of sleep. These may include:
Detecting Sleep Stages
Sleep is divided into different stages:
- Light Sleep - The body starts to relax, and breathing slows.
- Deep Sleep - The body repairs itself, and brain activity slows.
- REM Sleep - The stage where dreaming occurs, and the brain is very active.
Sleep trackers use sensors to detect changes in movement, heart rate, and breathing patterns to estimate how much time is spent in each stage. Have trouble sleeping or don't feel like your best self?

Monitoring Movement
Most sleep trackers use an accelerometer, a sensor that detects movement. If a person moves a lot at night, the tracker may classify that period as restless sleep. Minimal movement suggests deeper, more restful sleep.
Measuring Heart Rate and Breathing
Heart rate tends to slow during deep sleep and increase during REM sleep. Many advanced sleep trackers use optical heart rate sensors to measure pulse changes throughout the night. Some devices also monitor breathing rates, which can help detect potential sleep disturbances such as sleep apnea.
Recording Sleep Duration
Sleep trackers detect when you fall asleep and wake up by analyzing movement and heart rate changes. Some devices require you to manually start and stop tracking, while others automatically detect sleep based on inactivity.
Detecting Sleep Disruptions
Frequent awakenings can reduce sleep quality. Sleep trackers identify these disruptions by noticing sudden changes in movement, heart rate, or breathing patterns. This can help users recognize potential sleep disorders or habits affecting rest.
Sound and Snore Detection
Some sleep-tracking apps use the microphone to record sounds, detecting snoring or environmental noises that may be disturbing sleep. This can be helpful in identifying breathing problems or noisy sleep environments.
Common Sleep Disorders Sleep Tracking Can Detect
Many people experience sleep issues in the United States and worldwide.
Sleep tracking can help identify patterns that may indicate an underlying condition. By monitoring sleep duration, movement, breathing, and heart rate, sleep trackers can detect signs of common sleep disorders. While these sleep-tracking devices can't provide a medical diagnosis, they can pinpoint potential issues that may require further evaluation by a doctor.
Some studies show that sleep deprivation can lead to a substantial decrease in testosterone production. If that's the case, you can use Male Excel's testosterone replacement therapy (TRT) to help restore balance. That being said, here are some of the most common sleep disorders that sleep tracking can help detect:
Insomnia
According to one report, 25 Million adults in the US have insomnia.
Insomnia is a condition where a person has trouble falling asleep, staying asleep, or waking up too early and struggling to fall back asleep. People with insomnia often feel tired during the day despite spending enough time in bed. Here's how sleep tracking helps:
- Records how long it takes to fall asleep (sleep latency).
- Tracks total sleep duration and number of nighttime awakenings.
- Helps identify patterns, such as poor sleep quality on stressful days.
If a sleep tracker shows consistently short sleep duration or frequent wake-ups, it may suggest insomnia.
Sleep Apnea
Sleep apnea is a serious disorder where breathing repeatedly stops and starts during sleep.
These pauses in breathing reduce oxygen levels and can lead to excessive daytime sleepiness, headaches, and long-term health risks. About 30 Million people alone in the US have sleep apnea. This shows how common the disorder is among the populace. Sleep tracking can help:
- Monitors blood oxygen levels (in some advanced sleep-tracking apps).
- Detects irregular heart rate patterns.
- Records snoring or breathing disturbances (in sleep-tracking apps with sound monitoring).
If your sleep tracker shows frequent breathing interruptions or sudden drops in oxygen levels, it could indicate sleep apnea and should be evaluated by a doctor.
Restless Legs Syndrome (RLS)
Restless Legs Syndrome causes an irresistible urge to move the legs, often due to discomfort.
This can make it difficult to fall asleep and stay asleep, leading to daytime tiredness. Sleep tracking devices help you detect excessive leg movement during sleep, determine frequent nighttime awakenings caused by discomfort, and track how long it takes to fall asleep, as RLS can delay sleep onset.
Narcolepsy
Narcolepsy is a neurological disorder that affects the brain's ability to regulate sleep-wake cycles.
People with narcolepsy may experience extreme daytime sleepiness and sudden sleep attacks. With most sleep trackers, you can identify irregular sleep cycles, monitor excessive daytime napping and sudden transitions into REM sleep, and even track nighttime sleep interruptions, which are common in narcolepsy.
Circadian Rhythm Disorders
Circadian rhythm disorders occur when a person's internal clock is out of sync with their desired sleep schedule. This can lead to difficulty falling asleep or waking up at the right times. When a sleep tracker shows that sleep and wake times are inconsistent, it may indicate a circadian rhythm disorder.
Hormones and Sleep: The Link Between Testosterone, Cortisol, and Restorative Sleep
Your body's ability to get quality sleep isn't just about good habits—it's also influenced by hormones like testosterone and cortisol. Sleep and hormones have a two-way relationship:
- Poor sleep can disrupt hormone levels
- Hormonal imbalances can negatively affect sleep
Testosterone and Sleep
Testosterone plays a crucial role in energy, recovery, mood, and overall well-being. It also affects sleep in key ways:
- Testosterone is primarily produced during deep sleep, especially in the REM stage.
- Poor sleep lowers testosterone levels, leading to fatigue, low libido, and decreased muscle recovery.
- Low testosterone is linked to insomnia and sleep disturbances, making it harder to stay asleep.
If you're struggling with restless nights and constant fatigue, low T could be a factor. Tracking your sleep can help identify ongoing sleep issues, which may signal the need for hormonal testing and treatment.
Cortisol: The Stress-Sleep Disruptor
Cortisol, the stress hormone, should be highest in the morning and gradually decrease throughout the day. However, chronic stress and poor sleep can keep cortisol levels high at night, leading to:
- Difficulty falling asleep
- Frequent nighttime awakenings
- Light, unrefreshing sleep
Over time, high cortisol can further suppress testosterone production, worsening sleep quality and overall health.
How Sleep Tracking Can Help
While sleep trackers can't measure hormone levels, they can detect patterns like:
- Frequent wake-ups that may be linked to hormone imbalances
- Restless or poor-quality sleep, which could indicate low testosterone or high cortisol
- Sleep deprivation patterns that could be impacting natural testosterone production
If your sleep tracker shows persistent sleep disturbances, it may be worth checking your hormone levels with a specialist.

Benefits of Sleep Tracking
A good night's sleep is vital to your well-being and overall health. However, many people struggle to get the rest they need.
According to the Centers for Disease Control and Prevention's (CDC) study, 1 in 3 adults in the US don't get enough sleep. Sleep tracking can help you better understand your sleep patterns and make improvements. Whether you use a wearable device such as a smartwatch, phone app, or a dedicated sleep tracker, monitoring your sleep can provide valuable insights.
Listed below are a few benefits of sleep tracking to help individuals and healthcare professionals manage sleep issues more efficiently:
Identifies Sleep Patterns
One of the biggest advantages of sleep tracking is that it helps you understand your sleep patterns (or sleep habits).
You can recognize patterns in your rest by monitoring:
- When you fall asleep
- How long do you sleep
- How often do you wake up
For instance, you may notice that you sleep better on nights when you exercise earlier in the day or that you wake up frequently after eating a late-night snack. Understanding these sleep patterns can help you make better lifestyle choices to improve your sleep.
Detects Sleep Disruptions
Sleep tracking can reveal disturbances that affect sleep quality.
Many people experience restless sleep without even realizing it. Don't believe us, believe the stat: About 50-70 Million people in America experience sleep disturbances or disorders. A sleep tracker can help detect frequent awakenings, tossing and turning, or even potential breathing patterns and issues such as sleep apnea.
If your tracker shows that you wake up multiple times a night or spend too little time in deep sleep, it may indicate an underlying issue. It's best to identify these problems early so that you can take proactive steps to improve your sleep or seek medical advice.
Improves Sleep Hygiene
Sleep hygiene refers to habits and practices that contribute to better sleep quality. Sleep tracking helps you build good sleep habits by showing what works and what doesn't. For example, your tracker may reveal that:
- You fall asleep faster when you avoid screens before bed.
- Drinking caffeine late in the day reduces your sleep quality.
- Sticking to a regular bedtime helps you wake up feeling more refreshed.
When you make small adjustments based on your sleep data, you can create a healthier bedtime routine and improve your sleep quality over time.
Provides Useful Data for Medical Consultations
If you're struggling with persistent sleep problems, your sleep tracker data can be valuable for a doctor or sleep specialist. Instead of relying on memory, you can show them concrete data about your sleep patterns, including:
- Total sleep time.
- Frequency of nighttime awakenings.
- Variations in sleep quality over time.
This health data can help medical professionals diagnose sleep disorders such as insomnia or sleep apnea more effectively and recommend appropriate treatments.
Tracks Progress Over Time
When you make changes to improve your sleep, tracking helps you measure whether those changes work.
If you start going to bed earlier, using blackout curtains, or meditating before sleep, your tracker can show if your sleep quality improves. Seeing positive results can motivate you to maintain healthy sleep habits. If certain changes don't work, sleep-tracking technology helps you adjust your approach until you find what works best.
Potential Drawbacks of Sleep Tracking
While sleep tracking offers valuable insights, it's important to recognize its limitations and potential downsides:
1. Sleep Anxiety & Obsession ("Orthosomnia")
Focusing too much on sleep data can create stress about sleep quality, making insomnia worse. Some people become obsessed with getting a "perfect" sleep score, which can actually harm their rest.
Tip: Use sleep tracking as a guide, not a strict rule. If you feel well-rested, don't let a bad sleep score convince you otherwise.
2. Over-Reliance on Data Over How You Feel
A sleep tracker may say you had a poor night's sleep, even if you wake up feeling fine. This "nocebo effect" (expecting to feel worse) can make you mentally believe you're more tired than you actually are.
Tip: Trust how you feel first, and use sleep tracking as a secondary tool rather than a diagnosis.
3. Inaccuracy & Misinterpretation
Most consumer sleep trackers don't measure brain activity, meaning they estimate sleep stages based on movement and heart rate—which isn't always accurate. They can also mistakenly flag normal variations in sleep as problems, leading to unnecessary worry.
Tip: If you suspect a serious sleep disorder, consult a professional instead of relying solely on a sleep tracker.
4. Privacy & Data Concerns
Many sleep tracking apps collect sensitive health data, which may be shared with third parties.
Tip: Always check an app's privacy settings and be mindful of where your data is store
Different Sleep Tracking Devices or Methods
Sleep tracking can be done in various ways, depending on the level of detail you need. From simple smartphone apps to advanced medical studies, here are the most common methods used to monitor sleep:
Wearable Sleep Trackers
Wearable devices such as smartwatches and fitness bands are among the most popular sleep-tracking tools.
They monitor sleep using accelerometers (to detect movement), heart rate sensors (to measure changes during different sleep stages), and oxygen level sensors (to detect breathing issues). Some popular wearable trackers include Fitbit, Apple Watch, and Garmin devices.
Non-Wearable Sleep Trackers
These trackers are placed under your mattress or on your nightstand to monitor sleep without being worn.
They use pressure sensors to detect movement, microphones to record breathing and snoring, and radar technology (in some advanced models) to track sleep stages. Examples include the Withings Sleep Analyzer and Google Nest Hub's Sleep Sensing feature.
Smartphone Sleep Tracking Apps
Many smartphone apps use microphones and motion sensors to analyze sleep. These apps help:
- Detect sounds such as snoring or sleep-talking.
- Monitor movement when placed on a mattress.
- Provide sleep reports based on trends.
Popular apps include Sleep Cycle and Pillow.
Medical Sleep Studies (Polysomnography)
For serious sleep issues, doctors recommend a polysomnography (PSG) test, conducted in a sleep clinic. It helps measure brain activity (EEG), breathing and oxygen levels, and heart rate and movement. While sleep trackers provide useful insights, medical studies offer the most accurate diagnosis for sleep disorders.
How to Use Sleep Tracking to Improve Sleep
No matter the tech, if you want results, you must use it correctly. As we mentioned, sleep trackers can help you understand your sleep patterns and make changes for better rest.
Here's how to use it effectively:
- Track Your Sleep Regularly: Consistency is key. When you track your sleep regularly, it helps identify long-term patterns and recurring issues.
- Compare Sleep Data with Daily Activities: Sleep tracking apps allow users to log lifestyle habits, such as caffeine intake, exercise, and screen time. Compare this data to determine what factors affect sleep quality.
- Follow a Consistent Sleep Schedule: Monitoring sleep can help individuals establish a regular bedtime and wake-up time, improving circadian rhythm regulation.
- Make Adjustments Based on Data: If sleep tracking reveals poor sleep quality, people can adjust factors like room temperature, noise levels, or bedtime routines.
- Share Data with a Doctor: If tracking data consistently shows sleep disturbances, it's advisable to consult a healthcare professional for further evaluation and potential treatment.
Limitations of Sleep Tracking
While sleep trackers can provide helpful insights into sleep patterns, they are not perfect. Like any other tech, they have limitations that users should know.
Lack of Medical Accuracy
Most consumer sleep trackers rely on movement and heart rate data to estimate sleep stages, but they are not as accurate as medical sleep studies. They don't measure brain activity, which is the gold standard for detecting different sleep stages.
Unable to Diagnose Sleep Disorders Alone
Sleep trackers can highlight potential issues such as frequent awakenings or breathing irregularities. However, they can't diagnose sleep disorders like insomnia, sleep apnea, or restless leg syndrome. Even if a tracker suggests poor sleep, a medical evaluation is still necessary.
External Factors Can Skew Results
Things such as sleeping with a partner or pets or using an electric blanket can interfere with tracking accuracy. For example, movement sensors may pick up your partner's movements instead of yours.
May Cause Sleep Anxiety
For some users, constantly checking sleep data can create stress or obsession over sleep quality, which may lead to worse sleep. This is called orthosomnia, where people worry so much about sleep tracking that it actually disrupts their rest.
Conclusion
Sleep tracking is a powerful tool that helps identify and manage sleep disorders.
By tracking sleep patterns, detecting irregularities, and guiding lifestyle changes, sleep trackers empower individuals to take control of their sleep health. While sleep tracking can't replace a medical diagnosis, it provides valuable insights that help individuals and healthcare professionals make informed decisions about sleep quality. If sleep problems persist, consulting a doctor or sleep specialist is the best course of action.
Making sleep a priority and using technology to track progress can lead to healthier, more restful sleep. By understanding your sleep patterns and making necessary adjustments, you can improve your overall well-being.
