A new sleep staging algorithm has been revealed by Oura. The latest technology, which will be available via the Oura Ring, uses movement, temperature, heart rate and HRV data collected by the wearable to monitor your sleep quality. The algorithm's output matches results from polysomnography by up to 79%.

Oura has announced a new sleep staging algorithm for its Ring wearable. The company claims the technology is "the new gold standard in wearable sleep tracking". The algorithm has been developed over the past couple of years, with research published in the Sensors journal. Movement, temperature, heart rate and HRV data collected by sensors in the Oura Ring are processed by the algorithm, providing analysis of the four sleep stages: wake, light, deep and rapid eye movement (REM). 

Oura claims that the technology is 79% accurate when compared to polysomnography. For context, the company suggests the average sleep-tracking wearable has 60 to 65% accuracy. The algorithm has been built around a dataset containing over 1,200 nights of sleep from a diverse range of study participants living in different countries and with varying body types. The dataset also contains information from people with sleep disorders, and the technology is optimized for people aged 15 to 73.

Alongside sleep tracking, you can use the Oura Ring smart health wearable to log your exercise and monitor your heart health. The gadget can last up to seven days on a single charge and fully recharges in 20 to 80 minutes. You can currently get US$50 off the Oura Ring Gen3, a Black Friday deal offered until Cyber Monday (November 28).
