The Right Way to Fight Allergies
If the change of the season makes you sneeze, chances are you'll try almost anything to tame your allergy symptoms.

We asked Rebecca Gruchalla, PhD, professor of internal medicine and pediatrics at University of Texas Southwestern Medical Center at Dallas, which tricks help.

What Works
 
Bedding covers. Use allergy-proof zip-on covers for your mattress, box spring, and pillows to prevent dust mites from snuggling with you.

Limiting humidity. Many allergens thrive in moist environments, so use a dehumidifier or air conditioner to lower your home's humidity level.

What's Iffy
 
Air filters. While they can remove airborne allergens such as pet dander, they don't work on dust mites, which typically settle on surfaces.

Vacuuming. You'll just stir up allergens in the air. Invest in a vacuum fitted with a HEPA filter to trap particles.

What's a Waste
 
Opening windows. You're basically inviting outdoor allergens indoors. Use an air conditioner instead.

"Hypoallergenic" dogs and cats. Buying a hairless pet won't help -- dander from a pet's skin is what triggers allergies. If you already have a pet, bathe him regularly and keep him outside as much as possible.
