Screenshot from Oura ring app showing a cloudy sky with red sunlight illumination. At the top the text shows Readiness 89, Sleep 88, Activity 94, Heart Rate 60. In the middle it says "Symptom Radar" with "Major signs" below it. The explanation text says "Even with an optimal Readiness Score, your biometrics show major signs of something straining your body. Prioritize rest today to help maintain your readiness." There's then a "Learn more" button.
Yesterday I was a blob and didn't ride my bike at all or feel like doing much of anything. I went to bed early, set no alarm, and woke naturally but I also started coughing in the night. No surprise, my #Ouraring says that my temperature is elevated 0.3C among other things. 1/5
