Oura Ring 3 and 4 Can Now Detect When You're Getting Sick

Oura has fully rolled out Symptom Radar for its Ring 3 and 4, a feature that detects when users are beginning to get sick by monitoring changes in their data. The wearable tracks metrics like skin temperature, respiratory rate, resting heart rate, and inactive time, cross-referencing them with the user's demographic and age information.
