Beyond the Sleep Score: What is a Circadian Score and Which Wearables Offer It?

The sleep tracking industry has been abuzz with the introduction of circadian scores, a metric that measures how well daily routines align with internal body clocks. While sleep scores have long been the gold standard for gauging a good night’s rest, they only tell half the story. A growing body of research suggests that neglecting our circadian rhythm can lead to problems such as fatigue and insomnia, as well as increased risk of chronic diseases like diabetes and cardiovascular disease.

The reason we’re seeing a shift towards circadian scores is simple: sleep scores have limitations. They focus on quantifying how well we sleep rather than why we might be sleeping poorly in the first place. A high sleep score can mask underlying issues with our circadian rhythm, which regulates not just sleep but also hormones, temperature, and digestion.

Dr. Nisa Aslam, an expert in nutrition and advisor to Evera Nutrition, explains that our circadian rhythm is heavily regulated by the sleep hormone melatonin. “It’s a time keeper,” she says. However, restoring balance requires more than just one hormone – it involves a delicate interplay between light exposure, behavior, and neurotransmitter support.

Modern life often disrupts this balance. Irregular sleep schedules, artificial light, and travel can all throw our internal clocks out of whack, making it harder to wind down and relax at night, leading to insomnia and other sleep-related problems. A circadian score measures how well daily routines align with our natural body clock, providing valuable insights into why we might be struggling with sleep.

For the average person, this means that simply tracking sleep scores is no longer enough. We need to start paying attention to our daily habits and routines, making adjustments accordingly. This might involve exposing ourselves to morning sunlight, avoiding screens before bed, or adjusting meal times to better align with our natural circadian rhythm.

The wearables market is responding to this shift in focus, with several devices now offering circadian scores as a key feature. The Rhythm Ring offers a Circadian Score rated on a scale of zero to 100, providing users with valuable insights into how their daily habits are impacting their sleep. Other devices, such as the Ultrahuman Ring AIR and the Circular Ring 2, also offer circadian tracking features that can help users optimize their daily routines.

However, relying on wearables alone may not be enough to fix our sleep problems. As Dr. Aslam notes, restoring balance requires more than just one hormone or device – it involves a fundamental shift in how we approach our daily lives. This means making sustainable lifestyle changes that prioritize self-care and relaxation rather than simply relying on technology to solve the problem.

The limitations of sleep scores and the importance of circadian rhythm tracking are essential to recognize as we move forward. By paying attention to our internal clocks and making adjustments accordingly, we can improve not just our sleep but also our overall health and well-being. The future of sleep tracking is all about aligning daily habits with natural rhythms – and it’s time we take a more holistic approach to achieving better rest.

The wearables market has been abuzz with circadian scoring features, but it’s essential to separate hype from reality. Not all devices are created equal, and some may offer more accurate or comprehensive tracking than others. For example, the Oura Ring 5 offers a Body Clock feature that helps users optimize their daily schedules based on their sleep chronotype – but this requires consistent wear for at least 90 days.

Other devices, such as the Withings Sleep Analyzer, factor Regularity scores directly into overall Sleep Score calculations. However, these features may not provide standalone circadian scoring capabilities. As we navigate this complex landscape, it’s crucial to do our research and choose devices that align with our individual needs and preferences.

The shift towards circadian scores marks a significant turning point in the sleep tracking industry. By acknowledging the limitations of sleep scores and prioritizing circadian rhythm tracking, we can gain a deeper understanding of why we might be struggling with sleep. This new era of research promises to unlock fresh insights into the complex interplay between our internal clocks, daily habits, and overall health.

Sustainable lifestyle changes are key to achieving better rest. By prioritizing self-care, relaxation, and a balanced circadian rhythm, we can improve not just our sleep but also our overall well-being. The future of sleep tracking is all about aligning our daily habits with our natural rhythms – and it’s time we take a more holistic approach to achieving better rest.
