I completely agree with this statement. It is true that a society of this nature does tend to be destructive in general instead of a selective cleanliness. Although I think our society has still not made backward steps. It is also true that our body does work of a relationship with other organisms, particularly the ones on our skin is a good example. They actually are less in count when it gets colder, which shows why we tend to be sicker during the winter.
What you should do then is work to make your environment more healthy to your body than to continue as it is. What you can do is you should filter out your air so that it no longer has these harmful particles in it. I found that a Polarized Media Filter (which is a whole house filter that uses your furnace's air patterns) will take care of these excess particles as well as control the smell.
I used to have problems with the air in my home, but after speaking with a colleague of mine, she directed me to this type of filter. After doing a bit of research I decided it was a good bet as the system actually made sense. I found that the problems I had before no longer appeared. So I would definitely suggest this to you.
The best place for price I've found is at www.airlifeone.com. It is cheapest when you look for the Electrobreeze brand, which they have two types of filters, but as I understand the other product is not really any different save in a higher price.
Well, I hope that this helps.
