Prevention:

Breastfeeding can help prevent and decrease allergies. There is also evidence that exposures to certain allergens in the first year of life may prevent some allergies.

Mold spores are everywhere. You can reduce your exposure to mold by following these steps:

• Keep rooms dry, and use a dehumidifier, if necessary.
• Throw out moldy or mildewed articles (such as books, toys, and shoes).
• Use synthetic fabrics for clothing and household furnishings whenever possible. Disinfect bathrooms, basement walls, and furniture with diluted bleach or other disinfectant solutions.

Clean frequently to reduce dust. Vacuum frequently, preferably using a small-pore filter to capture dust mites. Damp-mop and dust often.

Eliminate as many "dust catchers" as possible, including rugs, bed ruffles or canopies, and curtains.

You can buy special covers for mattresses, box springs, and pillows to reduce dust mites. Wash rugs, bedding, and furniture coverings in hot water (at least 130 degrees Farenheit) weekly if possible.

Central heating and air-conditioning systems may be helpful, particularly if they include special filters to capture dust. Change furnace filters frequently. Use of high efficiency particulate air (HEPA) filters are most helpful in preventing mold exposures.

People who are allergic to animals may need to avoid keeping pets. Frequent bathing and grooming of the pet (preferably by someone who is not allergic to the animal) may help. Allergy to animals may also include wool, which may contain tiny amounts of dander (skin).
