Have you had a sleep study done? You may have low oxygen saturation when you sleep. I had literally no symptoms of sleep apnea, no major risk factors, but my body was struggling to breathe when I slept due to my anatomy. I have started CPAP treatment and am excited to see if my cognition improves despite not really feeling bad.

So far I haven't, nope, though it might be worthwhile to look into, given that I basically need 8+ hours of sleep to function well. I do have a fitness watch though that can (supposedly) measure SpO2, and while that showed the occasional dip, it seemed more like a measurement error, and generally the values were in the normal range.

  I've a FitBit Sense 2 and as I understand it that measures variations in SpO2. I'm not convinced how accurate nor how quickly it responds, it derives an estimate rather than directly measuring. I think it's also sensitive to any movements of the watch on your wrist. I also have had a finger pulse oximeter which logs and exports to an app via USB. If I sleep with that on it seems to be very reliable at recording the levels, the data certainly looks good and feels much more reliable than the Sense.

  My Apple Watch showed no major desaturations. The desats only last a few seconds.

Oh wow this is the first time I've read about this. Did you wake up frequently during the night or were there any other signs? I have somewhat of a deviated septum, and even had surgery done half a year ago, but it didn't really change much unfortunately. I always need >=9 hours of sleep to feel good. I've slept on average 7 hours the past 2 weeks & I feel horrible (completely different reason for the reduced sleep). I did a sleep study a few years ago because I suspected sleep apnea, but because of anxiety or sleeping in a new place, I only ended up sleeping 1-2 hours that night. They didn't find anything, but I wonder if I should try again.

  I don’t have memories of waking up frequently, but you tend to forget shorter wakeful periods. No other signs. No snoring, nothing that would indicate sleep issues. I have headaches but they are related to other sinus issues, though the doctor seems to think the CPAP should help. I’m not so sure but open to the possibility!
