Do Sleep Trackers Actually Work? Things You Should Know About

​Sleep Trackers​

Technology now offers detailed sleep monitoring, with many users changing habits based on tracker data. However, experts advise caution, noting current limitations in interpreting these sleep statistics.

​Sleep Trackers: Not Medical Diagnoses ​

Most sleep trackers haven't undergone strict FDA testing, classifying them as "lifestyle" rather than medical devices. Consequently, they are useful tools for general awareness but cannot diagnose or treat sleep disorders.

​Data Accuracy Varies ​

Tracker accuracy can be inconsistent, as they often estimate sleep via movement. Stillness while awake might be misread as sleep, and vice versa, leading to potentially flawed data interpretation.

​Polysomnography The Precise Standard ​

Sleep lab tests using polysomnography offer far greater accuracy by monitoring brain waves and other physiological markers. This method remains the gold standard for detailed sleep measurement, unlike movement-based trackers.

​Potential Downsides ​

Using sleep trackers might encourage pre-bed screen time, which hinders sleep. Having devices nearby can also lead to sleep-disrupting notifications, undermining a calm sleep environment.

​Benefits of Tracking ​

Trackers can help identify behavioral patterns impacting sleep duration and consistency. They offer a reality check on actual sleep hours, particularly for those with insufficient sleep syndrome, highlighting missed rest.

​Diagnosing Sleep Issues ​

Over-the-counter trackers aren't designed or approved to diagnose sleep disorders, though some newer devices offer suggestive features. Formal diagnosis requires consultation with a healthcare professional and specialized testing.

​The Risk of Orthosomnia ​

Obsessive focus on achieving "perfect sleep" metrics from trackers can create anxiety, paradoxically worsening insomnia. This condition, orthosomnia, highlights the importance of a balanced approach to sleep data.
