Children's Allergies: Causes, Triggers, and the Difference Between Them
Pollen is a big one. It can come from trees, weeds, grass and flowers. These tiny particles are released into the air to fertilize other plants. Pollen allergies tend to be seasonal, depending on the source of the pollen, and weather can often play a role, too.

They’re lovable and huggable, but dogs, cats and even some birds are another source of allergens, thanks to pet dander. Pet dander are tiny flakes of shed skin that can get in the air and on clothes, furniture and skin, and trigger allergies. Pet saliva and urine can also act as allergens.
These tiny critters are everywhere and are typically found in house dust. Dust mites appear year-round and thrive inside homes, making their way into furniture, carpets, bedding and upholstery.
Mold can live anywhere, indoors and outdoors, though they prefer to be in moist, dark places, like bathrooms and basements, or in piles of fallen leaves and gutters. To learn more about different mold types and the allergic reactions they cause, check out our article, Mold. The Fungus Among Us.
To put it simply, allergies are caused by an overreaction of the body’s defense system and triggers are allergens that can set them off. For a more detailed understanding of a typical allergic reaction, check out our visual guide on the anatomy of an allergy attack.
