• Oura Ring – Offers excellent accuracy in sleep tracking, particularly in **sleep efficiency** (SE) and **sleep duration**.

These devices use **accelerometers** and **motion sensors** to detect sleep patterns, providing reliable data for those looking to monitor their sleep duration over time. However, the level of accuracy can still vary slightly between individuals, depending on factors like movement and how the device is worn.

Sleep Stage Tracking: Can Devices Accurately Measure REM, Deep, and Light Sleep?

While devices like **Fitbit** and **Oura Ring** are quite accurate when it comes to basic metrics, the story changes when we look at **sleep stages** (REM, deep, and light sleep). Current consumer-grade devices are not as accurate in this area as one might hope.

“No consumer device tested—Fitbit, Oura, WHOOP, Garmin—was able to accurately quantify sleep stages (such as light, deep, or REM sleep) when compared to gold-standard EEG-based measurements.”

Devices like **WHOOP** and **Garmin** perform slightly better than others when it comes to tracking light and deep sleep, but their error margins remain high. None of these devices are recommended for making **health-related decisions** based on sleep stage data alone.

For those seeking precise information on their sleep stages, relying on these wearables may lead to inaccurate conclusions. As technology improves, we may see better sleep stage tracking, but for now, it’s safe to treat this data as an approximation rather than a definitive measure of sleep quality.
