Here’s what “allergy” actually means

An allergic reaction is the result of your immune system responding to an allergen, which is basically an irritant. When your body responds to an allergen, it produces antibodies called Immunoglobulin E (IgE). That causes your cells to release chemicals to rid the body of allergens. All those allergic symptoms — the sneezing, coughing,* and congestion* — are evidence of your body’s self-defense.3

If you’re allergic, you’ll recognize these symptoms

Whenever pollen in the air increases, so can allergic reactions. Your body can be allergic to any type of pollen and as the many different pollen counts fluctuate, an allergic reaction can be triggered.3

The common signs and symptoms of adult outdoor allergies include:2

  Runny/stuffy nose*
  Itchy, red, and/or watery eyes*
  General congestion or sinus pressure*

If you experience any of these symptoms, we recommend speaking with your primary care provider or an allergist. Discuss your symptoms and get a diagnosis.

How to cope

It’s very difficult to avoid plant pollen, but there are a few things you can do:2,4,5

  When you’re inside, keep doors and windows shut

  Run an air conditioner or air filter with certified allergy and asthma filters

  Avoid outdoor activities between 11:00 a.m.–3:00 p.m., when pollen counts are highest

  Wear a pollen mask

  Shower after being outdoors

  Avoid chores like mowing the lawn or raking leaves
