There are many causes of asthma, and what may trigger an asthma attack
for one person may be a trigger for another person. But there are some
causes or triggers that seem to trigger asthma attacks more than
others.
So what is causing asthma? Well, two of the biggest causes are
environment and diet.
Environment
For many people where they live and work is a major source for their
asthma problems. More specifically, what's in where they live and work
is what triggers their asthma attacks and causes their asthma symptoms
to get worse.
Dust mites, pet dander, mold, and pollen are some of the causes in the
home and in the workplace. While there isn't a whole lot you can do to
prevent these things in the workplace (except work from home), there
are a few things you should do in your home.
First, you need to clean your house often. Be sure to clean with a
HEPA vacuum so that you don't just put all the bad stuff right back
into the air. Also, any mold that you find in your home needs to be
removed immediately. It's best to hire someone to do it for you but if
you do it then make sure you do it right....
