Allergy season is different for everyone. That’s because different kinds of outdoor allergens - or irritants - get distributed into the air. Your seasonal allergies happen from exposure to mold spores or to the pollen that is being released by the local grass, trees and ragweed whenever that occurs in your area.

Outdoor mold allergies


Molds thrive in many environments, both indoors and outdoors. They flourish in damp, humid dwellings. Symptoms include:

  Itchy nose or throat

  Itchy, watery eyes

  Stuffy or runny nose

Learn how to avoid mold allergens.

Pollen allergies


Allergy symptoms from exposure to trees, grass, and weed pollen include:

   Sneezing

   Nasal congestion

   Runny nose

   Watery eyes

   Itchy throat or eyes

Ragweed allergies


Ragweed season occurs from mid-August to October when certain plant species - like sage and mugwort - distribute pollen into the air.5

Avoid bringing pollen into your home by removing clothes that you’ve worn outdoors and washing them right away.

Symptoms of ragweed allergies include:

   Sneezing

   Itchy nose or throat

   Itchy eyes

   Avoid gardening when your allergies are active

   Wear a face mask when you work outdoors

   Keep pollen out of your eyes with wraparound glasses
