@Davsey27,
That's a tough question. So many of us (me included) were exposed to these things earlier in life (I'm 75) and the many years result in so many more exposures to things that we had best avoid.
Allergies are common and in my case, they've only become worse with the passing of years. I have two air purifiers....one of the original larger models with a HEPA filter, and a newer much smaller version, also equipped with a HEPA filter (our bedroom) and the price is now about $100, much less than the original. It has helped considerably, but I'm always allergic to something or other.
It doesn't help that we have a well-ventilated back porch that exposes us to nature. No, we don't want to enclose it as it wouldn't be the same. Nothing really works for me and does contribute to that "sick" feeling.
The desert: Julie Rehmeyer wrote "Through the Shadowlands" ( a book about living in an RV and in the desert. Very interesting. As I recall she left the desert and returned to her RV. Very downscaled b/c of her multiple allergies. You may want to buy that book and read her story.
I know that Cort Johnson (the original founder of this site, but has now started another - Health Rising.com lives in the desert and moves from area to area. I can't/don't expect my husband to move there at age 78, and we do need plenty of medical care....so being near good medical facilities is important to us. You wouldn't have that availability in the desert.
My house is very clean....air ducts are immaculate and we do what we can to make the environment we're in as good as possible. Still, here I am coughing away as I write. It's tiresome and none of my doctors has an answer (and I really don't expect them to. You can only be helped with so much). I have multiple health factors going on, some of which are very common to my age group. I tried natural means first, combined with knowledgeable doctors and holistic therapies. Good nutrition is essential.
I was at the beginnig of the AIDS epidemic, when MS was still thought to be in "one's head," but during that time it became an accepted disease. I fully expected the research to be filtered down to us....but it never was. This was a major setback and we weren't taken seriously for many, many years. There was no information available, no internet....even the NIH had nothing on my other neurlogical illnesses. (Nothing can be called a disease until the medical establishment deems it to be so, proof has to exist and this includes scientific Thus, we're a collection of symptoms and go under the heading of a Syndrome).
This all gets very confusing, very fast....I would suggest that you learn as much as possible. I don't believe it will be proven to be just one thing, the years have taught me that much, if nothing else. We're all affected by so many symptoms in so many ways. Begin your journey, and I wish you luck. Research is probably 200% of what it used to be. But the causes are mutliple and have to be studied. Yours, Lenora.
