Allergy Causes & Allergy Triggers
Know your allergy triggers so you can avoid them
The things that cause your allergy symptoms are called your allergy triggers. Know your triggers and where they may be, so you can try to avoid them. Here is some trigger information to keep in mind:
Sources of Indoor Allergy Triggers:
- Pets. Dogs, cats, and other animals shed tiny flakes of skin called dander. Dander can cause allergy symptoms. Some people may also be allergic to an animal's saliva or urine.
- Rugs and carpets. Floor coverings often have dust mites. These are bugs so small that you can't see them. They can trigger your allergies.
- Beds. Dust mites and other allergens can be found in beds, including the sheets, pillows, mattresses, and box springs. Many people are also allergic to the feathers in comforters and pillows.
- Curtains and blinds. Curtains and blinds can collect dust that may have dust mites.
- Mold. Mold can cause allergy symptoms. It grows indoors in damp places like the bathroom.
- Cockroaches. Many people are also allergic to dried cockroach droppings and remains.
Sources of Outdoor Allergy Triggers:
- Trees, grasses, and weeds. All of these release pollen, which is a common allergy trigger.
- Mold. Mold can cause allergic symptoms. It can grow in damp places outdoors.
Doing yard work can expose you to pollens and outdoor molds.
