I pretty definitely can't breath through my nose as well as I should be able to (deviated septum), and have been wondering for a while how much this actually impacts me. What was your experience like?
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.
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!
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.
Deviated septum as well, but it's not the only reason for drying mucous membranes, which I never got around to getting checked. In part, it results from nutritional habits, sometimes (still), a bit too much coffee but the amount that causes it varies so it must be something else in one of the underlying metabolisms.
A few weeks ago, I tried Nasal Strips again, and for some reason, they are helping now and the difference is like day and night. I can only assume that it's because I got older and my life style changed, including nutrition, which was really bad when I was young. So dry mucous had too much effect for me to notice the benefits of the nasal strips or it's really just the bigger size of my nose :P
But the biggest change, compared to my young years, is that I am much more resilient to unhealthy stress and not continuously stressed as I was back then, when I was also regularly exposed to stress amplifications without time to recover.
And being able to breathe properly through my nose now amplifies everything for the much much better: mood, psychological resilience, performance --both cognitive and athletic-- time to fall asleep, sleep, with the latter two coming with their own boosts for the next day.
Most notable was the effect on my facial muscles. With the loss of those specific tensions came a direct effect on focus and concentration and self-control, which is all, to a great extent, mediated by the prefrontal cortex.
Just read Breath by James Nestor. You can thank me later. Fellow ran experiments on himself (and monkeys too) on exactly that, mousebreathing vs. nosebreathing. The difference is drastic. Catasthropically drastic.
