What Is Pollen Allergy?
An allergic condition in which plant pollen triggers an immune response in the body, causing symptoms like sneezing, runny nose, nasal congestion, and itchy eyes.
Spring Tree Pollen: The First Wave
Tree pollen from species like alder, birch, and oak is a classic early-spring seasonal allergen, though the exact timing varies by region and that year's temperatures. Pine pollen is also highly visible in spring but tends to have relatively lower allergenic potential due to its larger particle size.
Fall Weed Pollen: The Second Wave
Weed pollen from plants like mugwort, ragweed, and Japanese hop typically peaks around August to October, catching off guard many people who assumed their allergy season ended with spring.
Pollen Levels Vary Significantly by Region and Year
Which plants are prevalent and when they peak varies by region, so checking your local pollen forecast is far more useful than relying on a rough seasonal average.
Reducing Exposure With Masks and Glasses
Wearing a well-fitted mask and glasses during high-pollen periods can significantly reduce the amount of pollen reaching your eyes and nose.
Keeping Pollen Out of Your Home
Brushing off your clothes and hair before coming inside, and drying laundry and bedding indoors during high-pollen season, can meaningfully reduce pollen exposure at home.
Starting Treatment Before Symptoms Peak
Starting antihistamines before symptoms become severe — or while they're still mild — is known as "early treatment," and can significantly ease symptoms once peak pollen season hits.
Treatment Options Available From a Doctor
Beyond medications that relieve symptoms as they occur, allergy immunotherapy — including sublingual immunotherapy — gradually reduces the body's sensitivity to a specific allergen over time, and is worth discussing with a doctor as an option.
