quote: Researchers don't know why positive skin tests, allergy and asthma are increasing. One theory is that people simply don't go outside as often - Americans spend an estimated 90% of their time indoors - and have higher exposures to indoor allergens.
Another theory is that children become more vulnerable when they are exposed to fewer bacteria and viruses. Some researchers believe that has an effect on the developing immune system.
I think the obvious reason these are on the rise is people don't die from it anymore. Instead they grow up to have kids who inherit it.
I should have died twice by now thanks to my lovely asthma. The first time at age 12. And while I'm not having any kids, if I had odds would be good that they would have my allergies and asthma as well.
Why are they overlooking the genetic link? Or is it somehow un-PC? Too much like a call for Eugenics? (or is there no money for research if that's the cause?)

What about an increase in airborne pollutants?

I have read (I don't reacall where) that children who were around other childrent a lot (day care, siblings, etc.) got sick more often when they were very young, but had less allergies and asthma when they were older.

Teshi: Like pollen? I was never so sick as when I lived in a redwood forest. We need to burn those things down. :eyeroll:

Also, there may be a correlation between the indoor time and exposure to household molds. Modern building techniques, particularly insulation and vapor barriers, plus indoor plumbing and permanent carpeting, means a more air-tight environment with greater homespots for mold colonies.
The genetics thing also has merit as fatality rates from those ailments has dropped considerably in the last 30 years (about a generation and a half).
