Environmental Allergies

Environmental allergies involve an immune system overreaction to things that exist in our everyday surroundings, including home, work, and the great outdoors. You may also hear this immune system response referred to as hay fever or allergic rhinitis.


Allergy sufferers report a variety of symptoms, including:

  • Sneezing
  • Coughing
  • Runny nose
  • Nasal congestion
  • Itchy, watery eyes
  • Fatigue
  • Headaches
  • Wheezing
  • Dark under-eye circles
  • Hives

If your allergies are seasonal, symptoms will worsen when your allergens emerge into the environment. Any of these environmental allergies can trigger asthma.


An allergic reaction occurs when your immune system produces antibodies to fight an allergen, even though that allergen in itself is not a threat. The most common environmental allergens are pollen, dust, pet dander, mold, and cockroaches.

Pollen, a fine yellow powder, travels through the air thanks to the wind, insects, and other animals. Typically, spring brings tree pollen, late spring and early summer feature abundant grass pollen, and fall sees ragweed and other weeds. Many Central Texas residents also battle cedar fever (an allergic reaction to mountain cedar trees) December through March.

Dust mites cannot be seen with the naked eye. They are microscopic bugs that live in carpet, bedding, upholstery, stuffed toys, and bedding. Dust mites thrive in warm, human conditions, so this allergy may flare up most often in spring and summer but can cause problems year-round.

Pet dander
While exposure to animal saliva and urine can sometimes cause allergic reactions, pet dander (dead skin cells) is the most common source of pet allergies.

Molds live outdoors and in moist indoor environments. The spores float through the air like pollen, with outdoor levels peaking in late summer in Central Texas.

Cockroach droppings, saliva, and waste can trigger allergic reactions in some people.
