I grew up on the coast of Maine, USA, so elevation 0 and wooden houses and salty sea air. I attended college inland in a small city elevation ~100m. But was only there for 4 years and lived half the time in a concrete apartment and the rest in a wooden house. Then I moved to Munich, Germany, elevation ~500m, fresh mountain air, but the houses are all thick concrete, and a typical German custom is to air out the house often, otherwise the air gets stale.
Since I've lived here (16 years) I get sinusitis, rhinits and bronchitis at least once or twice a year. All the doctors just say something like "dry mountain air" and give me some nasal sprays, antibiotics and eucalyptus losenges and it goes away after a few weeks. But has been getting slowly and steadily worse over time.
Now for the past 3 years I feel like it's gotten so bad that I can't breathe properly when inside - especially when sleeping - which has given me sleep apnea which a CPAP machine does not help (makes it worse). I need to sleep with all the windows and doors open but still cough so much during the night, and of course in winter the dry, cold air is bad and I cough a lot, too. I just feel like I can't properly breathe when indoors, which is why I spend a lot of time outdoors where I can breathe freely. I instantly feel like I can't breathe as well when I go inside. And this has been the case in two different houses over the past 3 years, and we've taken measures to ensure clean, mold-free and perfume-free clothing and furniture, so probably not a contaminant issue. Plus my wife, who is asthmatic, has no problems whatsoever. But she grew up here.
So I guess my question is: can it be that I am just "allergic" to European stone housing or the mountain air? That it somehow slowly has been affecting my lungs? I'm seeing a lung doctor in a few weeks (has been tough to get an appointment with all the COVID stuff going on the past years), but I didn't know if anyone here has any knowledge or information on this kind of issue.
Also, I never tested positive for COVID, and the issue started a few months before COVID even existed. I'm also a smoker of 10 years, but it's no longer smoker's cough and seems to be more of just a problem getting fresh air at home. I actually breathe much easier when I'm outside having a cigarette and cough LESS.
Thanks in advance!
