year-round perennial allergies

Perenial allergies can occur year-round, because they are caused by allergens in your living environment�often your home. Common culprits include house dust mites (or more specifically, their droppings), animal dander, cockroaches, and feathers such as those in down comforters and pillows. Allergies can also be caused by certain foods or exposure to irritants such as paint fumes, cigarette smoke, chalk dust, or heavily polluted air.

To tame common indoor allergens, clear out the extra clutter in your bedroom, along with carpets and drapes; encase your mattress; box spring, and pillows in airtight, allergen-proof covers; wash bedding weekly in scalding water; and avoid bedding made of down, kapok, or cotton. Also, consider using a 3 percent tannic acid spray, which causes dust mite droppings to be less reactive, or benzyl benzoate, which kills the critters. Vacuum frequently using a double bag or a HEPA filter; wear a dust mask while cleaning; and use your air conditioner regularly, to reduce the growth of dust mites and mold. You might even consider an air-purifying system. Also, banish pets from the bedroom and careven from the house, if you can. And bathe cats and dogs weekly. To control mold, keep the house dry and well-ventilated and wipe down humid areas, such as bathroom surfaces, with a fungicide or bleach.
