Asthma in Homes

Asthma is a chronic disease that increases the lung passage sensitivity to many kinds of substances.  These substances are called ‘triggers’ when they cause a reaction in the lung passages.  Although triggers can occur in any environment, many occur in the home where people spend a large amount of their time. 

As a society we spend about 95 percent of our time inside buildings.  The indoor air can contain many things that trigger an asthma episode of coughing, wheezing, chest tightness, shortness of breath. 

Some of the most common triggers are:

  • Dust and dust mites
  • Pests – cockroaches and rodents
  • Pets – cats, dogs, rodents
  • Second-hand smoke
  • Mold, mildew
  • Nitrogen dioxide – from burning fuels
  • Volatile organic chemicals – VOC’s – odors and gases from a wide variety of substances
    • Perfumes
    • Household cleaners
    • Paints and varnishes
    • Candles
    • Room deodorizers
    • Glues
