More than 25% of adults and 20% of children in the United States experience seasonal allergies, resulting in over $3 billion in annual medical expenses.

Here's how to protect yourself from seasonal allergies:

Indoor Protection:

  • Keep windows and doors closed during allergy season
  • Install HEPA filters in HVAC systems
  • Regular cleaning to remove dust and allergens
  • Wash hands frequently
  • Clean or bathe pets regularly

Outdoor Prevention:

  • Monitor local pollen forecasts
  • Shower after outdoor activities
  • Change and wash clothes after being outside
  • Avoid outdoor activities during high pollen counts

Treatment Options:

  • Over-the-counter medications:
    • Antihistamines
    • Decongestants
    • Nasal and oral corticosteroids
  • Prescription medications
  • Allergen immunotherapy (allergy shots)

Common Seasonal Allergy Symptoms:

  • Sneezing
  • Runny or stuffy nose
  • Watery, itchy eyes
  • Itchy sinuses, throat, or ears
  • Ear congestion
  • Postnasal drainage

Seasonal allergies occur when the body reacts to airborne pollens from trees (spring), grasses (summer), and weeds (winter). Individual reactions vary, and you may be allergic to some pollens but not others.

Consult a healthcare provider if allergy symptoms significantly impact your daily life, as they can recommend appropriate treatment options and determine if immunotherapy might be beneficial.
