A sleek and wearable health-monitoring ring that performs similarly to in-lab sleep tests
Dimitriu told HuffPost that even though brain wave monitoring (EEG) is one of the most reliable methods for tracking sleep stages, it's a component that is missing from many commercially available sleep trackers. The Oura Ring, which he personally uses, is one device that seems to perform comparatively to this method.
"The Oura ring has had head-to-head studies
against an in-lab sleep test, and shown fairly good overlap in its ability to stage sleep," he said. "There's also no screen to be disruptive."
This non-intrusive and waterproof ring uses research-grade sensors to monitor everything from activity to stress levels. It sits on the finger, which can be a more ideal and accurate source for data gathering than other options that sit on the wrist. The connective app tracks and logs everything from sleep stages, key vital changes throughout sleep and bedtime routines in order to make personalized suggestions on when to wind down for sleep and achieve your sleep goals.
