So here is a curious thought. Do you feel you keep improving more over time? Or is it more the roller coaster ride of being in bad environments (whether cold or polluted) and then improving back to the new normal?
Since I improve so much in Hawaii, I always fantasized about staying there a month or two, but I do wonder just how far I really could improve. I need to make myself a plan for my future, and curious if avoidance is a long haul or short (ish) haul.
I've over the years encountered a phenomenon I call "the honeymoon effect". It happens almost always anytime I am traveling. I attribute it to the change in environment but maybe just sitting behind a drivers seat for 12 hours a day is less taxing than when I am at home doing chores and what not. But I usually feel much better.
I suspect it's getting a respite from whatever types of exposures I am getting at home also. A totally different environment gives me relief from the chronic day to day exposures I was having to endure. But this never last's because I am going to start becoming sensitized to the new environment also.
I have stayed in my dad's place in NC which is extremely moldy, and felt better while I was visiting. But when I moved up there I got as sick as I have ever been. Even as much as my initial moldy house. Probably more. It took about three weeks and I had to crawl out of there on my hands and knees and pitch a tent in the back yard.
I rented a room in a brand new house in Tallahassee once and the first week or two maybe was ok but I declined rapidly after that. I later discovered that it had water damage. Even though it was only about 2 years old.
I bought a brand new rv and was mostly bedridden when I was in it. I later discovered entry points for water in 2 or 3 different areas. So there was mold right from the get go. And I bought it new!
I have always done the best when I avoid any kind of construction that is conventional. Because there is no way you can inspect behind walls or panels or the roof to see what is happening back there.
If there is water damage, mold growth of any kind, rotten wood, past or present in conventionally constructed buildings and rv's then based on 24 years of these types of encounters I suspect strongly I will be made worse. And the more time I spend in the situation the worse I will become.
And the insidious thing about it is that I never know when it is happening. It's many times like being placed in a warm pot of water and slowly turning up the heat.
So I just try to avoid conventional construction altogether. Which isn't easy cause you can't socialize and you can't shop and see dr's and renew your license, etc. etc. etc. without going into buildings.
Fortunately all these exposures seem to have a direct relationship to the amount of time I am in them, and whether i have repeated exposures. Like when I lived next to houses for support or when I was staying with my dad in NC. I would be in a trailer but would end up going in the house for different things. And over time I suspect this had a cumulatively negative effect on me. Even though I limited it as much as humanly possible.
My main concern with non conventional construction, is outgassing and chemicals from drywall and styrofoam board insulation. I had a home made truck camper constructed in a way I can inspect for mold I was staying in. I carpeted the floor and it was constructed out of foam board and I covered it with visqueen. I did better in that but still had issues.
And now the new metal building I have insulated with fiberglass batting and sheathed the inside with styrofoam foam-board panels. I can still sometimes smell the foam board but for the most part it seems to be a low emitter of voc. But while I still have ups and downs I seem to be best here. I was visiting my neighbor regularly against my better judgment and had to put that to halt cause I was doing way worse than I would have expected. And I do feel better now but there are so many variables and confounders I will probably never really know.
And I didn't even touch on the fact that there is all types of airborne dust and mold and pollen outside. And what effect this has on me I am really not sure.
And you also have to consider placebo and nocebo effects.
And how much of this is environmental and how much is other things like food sensitivity and pushing myself beyond my energy envelope is anyones guess.
And I also constructed a building out of metal studs and drywall that was inside a bigger metal building so it's never been exposed to water like happens to drywall inside of conventional buildings. And I did extremely poorly in the 3 to 4 year period I was in that structure for whatever reason. Chinese drywall was a big issue at the time. I don't know if that had anything to do with it or not. It did conspicuously out gas "drywall smell" for a long long time.
My opinion is to try to avoid structures that have had mold in the past or have ongoing mold. But good luck on that, probably way North of 50% of all construction has either had issues that were not remediated properly or has ongoing problems. And it's hidden so you can't see it, so you don't know whether and to what extent there is a problem. And they just are not an issue for normal people. Just like peanut butter and gluten isn't an issue for normal people.
But what makes it so difficult is authorities are still in abject denial. So everyone is on they're own. It's an impossible situation unless you are wealthy, and can afford to buy a plot of land somewhere where code enforcement isn't going to come along and say "you can't camp in your back yard, or you can't build a metal building and live in it"
Oh, and you have Hvac systems that have duct work that can have mold growth in them, and so can evaporator coils and drip pans that can have mold growing in them. So you better know how to service them and do it regularly, or have the cash to have someone do it for you.
It's an impossible situation!
