Seasonal Allergies

What are they?
Seasonal allergies are a group of symptoms usually affecting the nose, eyes, and throat that occur after exposure to particles of dust, dander, mold or pollen. It may also be called allergic rhinitis or hayfever. You may not be sensitive to all pollen types. These symptoms may occur only in spring or fall. These symptoms can span more seasons or be present all year.

Cold or Allergy?
Some symptoms are very similar. In general people with allergies:
  • Do not have a fever
  • Often have an itchy nose and itchy eyes
  • Symptoms usually can last weeks or months (Cold symptoms usually last 7-10 days)
What to do?
  • Avoid or limit exposure to what is causing the allergy, (known as the allergen). Repeated exposure to allergens can worsen symptoms.
  • Use washable curtains and bedding.
  • Place pillows and bedding in washable covers.
  • Avoid cats, dogs or other pets if you are allergic to them.
  • Keep humidity in the house moderate.
  • Take (over-the-counter (OTC) and/or prescription medications.
If you have allergies to outside allergens,
  • Spend time outdoors only when pollen counts are lowest (early morning and late afternoon).
  • Change your clothes and take a shower when you come home.
  • Keep pollen out of the house - Use air conditioner instead of opening doors and windows.
  • Let someone else mow the lawn. Keep grass short.
