Our Allergies Quiz Is Nothing to Sneeze At

Studies show that probiotics — beneficial microorganisms that support gut health — are linked to a healthier immune system. So while probiotics are not a cure for allergies, a healthier gut may reduce allergy symptoms.

HEPA-certified air purifiers have proven effective at trapping allergens. (HEPA stands for “high-efficiency particulate air.”) Only air purifiers labeled “HEPA-certified” contain air filters that meet the U.S. Department of Energy’s strict standards for air filtration, which means they must trap 99.97 percent of particles 0.3 microns or larger. Place air purifiers with HEPA-certified filters in rooms where you spend the most time (like the bedroom or living room) to reduce allergen exposure. Note that “HEPA-like” and “HEPA-style” purifiers are not the same as HEPA-certified — and avoid them.

While a humidifier can add moisture to the air and reduce pollen levels, excessive humidity can create an environment conducive to dust mites and mold, both common allergens.

Washing your clothes and bedding immediately in hot water helps eliminate dust mites, pollen and other allergens that may have clung to them when outdoors. Avoid drying clothes outside; they may collect more pollen that way.

Moving to a region with different plant species makes it easier to withstand the pollen they produce, although it may take time to adapt to the new allergens.
