What’s a sleep tracker ring?

At its core, a sleep tracker ring is an innovative self-tracking technology that happens to take the form of a regular ring. These are commonly referred to as smart rings, and they incorporate various sensors and technologies to monitor your nighttime rest. They can detect disturbances, assess sleep stages such as deep and REM sleep, monitor heart rate and respiration rate, and might even track variations in body temperature.

Paired with companion apps, they offer detailed insights into your sleep habits, enabling you to make informed adjustments. Although they are not a substitute for professional medical advice, sleep tracking rings serve as valuable tools for those seeking a better understanding of their sleep quality and potential areas for improvement in their nightly rest.

Benefits of sleep tracking rings

Sleep tracking rings are equipped with sensors, algorithms, and a multitude of benefits that can diligently monitor essential sleep metrics. These benefits include providing personalized insights, continuous health monitoring, and data storage. These unobtrusive self-tracking devices reveal that the secret to restful sleep might literally be at your fingertips.

Here are some of the most compelling benefits of sleep tracking rings:

  • Sleep scoring. Sleep tracking rings often use scoring systems to provide personalized sleep scores and detailed reports. These scores encompass sleep duration, efficiency, the presence of awakenings or disruptions, and various other parameters. They are intended to guide better sleep habits. However, it's important to remember that what constitutes good sleep may differ across individuals.
  • Health monitoring. While sleep tracking is the primary focus of these devices, many of them also offer additional health-related features. They go beyond mere sleep duration and quality tracking by providing insights into health metrics such as heart rate, body temperature, and oxygen saturation, to name a few.
  • Data-driven recommendations. Sleep tracking rings offer data-driven recommendations that provide personalized insights and actionable suggestions to enhance your sleep quality. These recommendations may include establishing optimal bedtime routines, wake-time suggestions, and optimizing your sleep environment.
  • Sleep trends and patterns. Tracking sleep data over time helps us understand our sleep behaviors, including duration, bedtime, and wake-up times. It uncovers patterns in sleep cycles, revealing deep, light, and REM sleep stages, offering a window into our nightly routines.
  • Smart alarms. These alarms are designed to wake you up at the most optimal time within a specified window, usually when you are in a lighter sleep stage. This aligns the alarm with your natural sleep cycles, making waking up in the morning a more pleasant and energizing experience.

What metrics can a sleep tracking ring measure?

While research on self-tracking measures is limited, sleep tracking rings typically incorporate an array of sensors and technologies, all working together to assess various factors related to your sleep patterns and overall health. While the specific metrics that a sleep tracking ring can measure may vary depending on the make and model, here are some common metrics that most sleep tracking rings excel at monitoring:

Heart rate

Heart rate monitoring in sleep tracking rings provides valuable information about your sleep patterns and physiological responses during different stages of sleep. This monitoring assesses heart rate variability (HRV), reflecting the autonomic nervous system's activity, and is associated with relaxation.

Fluctuations in heart rate can provide valuable insights into your sleep quality and overall health. An elevated heart rate during sleep may signal awakenings, nightmares, or underlying health issues that require attention.

Sleep stages

The stages of sleep are integral to a good night's rest, promoting overall physical and mental health. They are typically categorized as non-rapid eye movement (NREM) and REM sleep, with each phase bringing about unique physiological changes.

While NREM comprises three stages, beginning with the light N1 stage, transitioning to the deeper N2 stage, and culminating in the restorative N3 stage, REM sleep, characterized by rapid eye movements, hosts vivid dreams and heightened brain activity. Throughout the night, these stages cycle, and monitoring them can offer insights into both sleep quality and overall health.


Certain sleep tracking rings include temperature tracking as a metric, which can help capture the subtle changes during the onset of sleep. Temperature tracking can also help delineate your journey through these sleep phases and pinpoint potential sleep disruptions, including awakenings. Some temperature sensors, like those of the Oura Ring, have been demonstrated to be effective tools for fever monitoring and early illness detection.

Blood oxygen level

Blood oxygen level monitoring, commonly referred to as SpO2 tracking, has become a valuable addition to the features offered by some sleep-tracking rings. This metric measures the percentage of oxygen-saturated hemoglobin in your bloodstream, providing insights into your body's ability to supply oxygen to tissues. During sleep, SpO2 levels can fluctuate, and these fluctuations may provide insight into sleep patterns, specifically when and how they change.


The best sleep tracking rings are equipped with sensitive accelerometers or motion sensors that continuously monitor the movements of your finger during the night. This technology allows them to detect even subtle changes in position or motion, providing valuable insights into your sleep behavior.

By analyzing these behavioral patterns, these devices calculate sleep efficiency — measuring the percentage of time spent asleep compared to the total time in bed. Understanding your movement patterns during sleep allows you to adjust your sleep environment and bedtime routines, ultimately improving the quality of your sleep.

Sleep-tracking metrics should be used as a tool for improving sleep quality but not as a substitute for medical advice or diagnosis.

How accurate is a sleep tracking ring?

The accuracy of a sleep tracking ring can vary depending on the specific device, its sensors, and the algorithms used for data analysis. In research, smart rings that are capable of measuring sleep are compared to Polysomnography (PSG), which is used to measure sleep in clinical settings. The studies found that smart rings underestimated or overestimated certain sleep measures.

It's important to acknowledge that no sleep-tracking device, not just sleep tracking rings, achieves 100% accuracy when compared to the gold standard of sleep monitoring, which is PSG conducted in a sleep laboratory.

Health risks of sleep tracking rings

Although sleep-tracking rings are popular for their convenience and generally considered safe for most users, there are some important considerations to keep in mind.

InaccuraciesSleep tracking rings may not always provide 100% accurate data, and overreliance on them could lead to incorrect conclusions about your sleep patterns and health
Sleep anxietyFor some, if sleep data does not align with their expectations, it can cause anxiety
Allergic reactionsCertain materials used in sleep tracking rings may trigger reactions in people with allergies or sensitivities
Wear-and-tearProlonged contact with the device could cause irritation

Remember that while sleep tracking rings can be handy and valuable tools for improving sleep quality, it is crucial to follow the manufacturer's guidelines and recommendations for safe and proper use. Additionally, try maintaining a balanced and healthy perspective on sleep data to prevent the development of any unwanted reactions.

Best sleep tracking ring — conclusion

For those in pursuit of quality sleep and a better understanding of their sleep patterns, sleep tracking rings have emerged as highly promising tools. They provide a wealth of valuable benefits, including the ability to monitor and analyze various health metrics, identify sleep patterns, and offer data-supported guidance.

That said, while they come with a host of benefits and can be valuable companions on your journey to achieving restorative sleep, it is essential to use them sensibly. Remember that they are not diagnostic tools for sleep disorders, and their accuracy can vary.
