Alcohol and AHI - ppca - 05-08-2019
I've gone through a few threads here, dealing with the same topic. Mixed reactions and different experiences, so here's mine.
Lots of times I take a nap after lunch. A good meal, combined with some alcohol, usually makes me sleepy, so I take a 1.5-2 hours nap. My AHI during that session is typically very low, and quite often zero. When I go to bed later that night (no alcohol), I typically sleep for another 6-7 hours, and my AHI is actually pretty good (anything between 1 and 2, in most cases), but always higher than during those sleep sessions after alcohol consumption.
It is also much easier for me to fall asleep after lunch (just a few minutes), while at night I am often struggling. Sometimes it can take an hour to fall asleep. I suppose the obvious answer is that a glass of wine, or a beer, after lunch helps to fall asleep faster.
It appears that moderate consumption of alcohol does tend to lower my AHI, and give me a good quality sleep (nap). During that short session, I do not wake up. It is typically a 1.5-2 hours sleep. No idea if I reach the REM stage or not, but normally I feel refreshed when I wake up. My overnight sleep is quite often a different story. I wake up multiple times, sometimes more, sometimes less, and the overall quality of sleep is not as good as during my naps.
I know one thing. I am definitely not going to drink more, in order to keep my AHI numbers lower (liver matters too
). Just wanted to share my experience with the forum.

I have the same experience with naps and AHI but there is no alcohol involved in my case. A couple of times a week I might take a 1-1.5 hour afternoon nap. I sleep soundly and my AHI is usually 0. At night my AHI is usually 1.0-2.0. I always figured the difference was because the apneas didn't kick in until after the first hour of sleep.

Napping is a once-a-year thing for me, but when I do go down because of a perceived deficit, I rarely sleep for more than one hour. That's not really long enough to get to the first REM stage after sleep onset. I think that REM and beyond invites changes to the body's tone or positional changes that cause more OSA's. Also, alcohol is a depressant, so it shouldn't be surprising to learn after the fact that you slept differently than otherwise. We would tend to be more immobile with a depressant riding our sleep.

Hmm...maybe my lower AHI during naps has nothing to do with alcohol consumption. As I said in the original post, my numbers are almost identical to yours: zero, or very close to it, during naps; 1-2 (sometimes a bit higher) at night.
However, with regards to apneas kicking in, I can see them in SleepyHead in the first hour, even in the first 20-30 minutes, during my night sessions...never, or very rarely during naps.
