The day opened high, running 215–229 mg/dL from midnight and easing below 180 by about 2 AM. Glucose then held mostly in range through the morning and midday, bottoming near 70 around 11:45 AM. Highs returned in the afternoon (about 190s around 2 PM, peaking near 220 around 5 PM) and again around 6:30–7:15 PM (up to 209). The only true low was a brief dip to 66 mg/dL at about 8:15 PM, lasting roughly 15 minutes. A steep evening climb followed, passing 200 by about 10 PM and reaching the day's peak of 313 mg/dL at 11:55 PM. Oura logged 6,327 steps, 1,189 active calories and about 9h 57m sedentary time, with 2 inactivity alerts.
Oura scored the night ending Saturday morning at 76, with 5h 18m asleep in a session running 11:09 PM to 4:56 AM. That lines up well with the CPAP, which logged 5h 46m in a single session (11:09 PM–4:55 AM), so the mask was on for essentially the whole night. Breathing looked clean: AHI 0.0 (obstructive 0.0, central 0.0) and a 95th-percentile leak of 0.0 L/min against the 24 limit. Oura sleep efficiency was a strong 92, though short total sleep (contributor 53) held the score back. Readiness came in at 54: HRV was low (average 13), the night's heart rate ran high (average about 100 bpm, low 89), and the recovery index contributor was weak at 26, so the clean CPAP numbers did not translate into much recovery.
There is no truth. There is only perception.
