For many people, fall means an end of hot summer days as temperatures begin to cool and trees begin to lose their leaves. During this time of year, the cooler temperatures have many people spending time outdoors enjoying the weather or playing sports.

Fall also means it is ragweed season which affects millions of people. Ragweed is considered to be the most significant allergy trigger in fall, although there are other plants that also release pollen during this time of year. Depending on where a person lives, ragweed pollen may be present from August through November. Mold is another common outdoor allergen during the fall. Piles of damp leaves or other organic material make for an ideal place for mold to grow and release spores into the air.

When people who are allergic to these substances come into contact with them, their immune system releases antibodies that attack the allergens. Histamines are released into the body and trigger the allergic reactions common to so many people. In fact the Centers for Disease Control and Prevention (CDC) reports that, “Allergies are the 6th leading cause of chronic illness in the U.S. with an annual cost in excess of $18 billion. More than 50 million Americans suffer from allergies each year.”

Both pollen and mold spores can travel great distances in the outdoor air. This can be especially true during windy fall days. These air quality contaminants can be a concern to both people spending time outdoors and even those indoors as these allergens can enter homes and buildings through open doors and windows, on people’s clothes, and through air intakes in HVAC systems.

For some people, these same airborne allergens could even trigger an asthma attack. For those who experience allergies all year long, they should also consider possible indoor allergens that they may be exposed to on a regular basis. Common indoor contaminants include mold, dust mites, pet dander, latex, insect and rodent allergens.
