Is there a lot of manufacturing/refining going on, besides the regular
rush hour car smog? Lack of trees maybe?
I once fell asleep in an MRI scanner. But I could probably sleep
through an nucular war.
Phoenix is in a valley thus the name....valley of the sun. Being a valley
we get temperature inversions that keep the warmer, polluted air down on the
ground. Most of the pollution is particulate matter from the surrounding
farms, construction and of course, auto traffic (FBR golf turney drumming up
real traffic congestion this week). This year is bad because the jet stream
has stayed way North which means little wind, no rain now for a record
number of days and daytime heating of the ground with the air aloft being
cold trapping the warm air...I think I said that?
Having lived in Asia for years, I grimace a bit when people talk about
the awful air quality in the Phoenix valley. Certainly it's not great
when it's at its worst - but after spending winters in China where you
literally could not see across a major street (not even a hint of
what's on the other side), I'd say "it's all relative". For those who
haven't been here, "bad air" means there is a brown tint to the layer
of air hanging over the city, and the mountains 20-30 miles away are
somewhat hazy (though still visible). I used to dream of visibility
like that in China in the winter (when the wind blew hard and long
enough to get it, I was amazed to see a mountain range I didn't know
was there out my kitchen window - this after living there for months).
FWIW, I've found the Arizona dry air to be more of a problem than the
particulate matter in the air. I've got a really, really big
humidifier and my sinuses are MUCH better when I use it.
The other thing that has helped my sinus condition is sinus irrigation
- basically pouring salty water in one nostril, through the sinuses
and out the other. Looks totally ridiculous, feels "odd" (not
unpleasant) but if you have sinus issues, DO IT. You'll thank me. I
tried to buy a professional product (Sinucleanse, I believe...) but
couldn't find it in stock anywhere... so I use a water bottle (works
perfectly - I just need to make sure and use one that will NEVER find
its way onto a bike!!!!!). ;-)
