Does anyone know the lowest amount of sleep that Oura measures as sleep? Is it 4 hours? Last night I was up super late (didn’t go to bed until 4am) and woke up around 6:30am. When I checked my Oura app it registered as a “nap” and not sleep. I then fell back asleep and when I woke up, I had 4 hours and 45 minutes of sleep total, and it registered it as sleep.
