How to Cut Down on Allergens

Allergens are substances that cause some people's immune system to overreact, resulting in symptoms such as sneezing, coughing, runny nose, itchy eyes and sore throat. Reactions are more serious for some people, and can cause asthma attacks and low blood pressure. According to the Asthma and Allergy Foundation of America, about 50 million people suffer from allergies in the U.S. alone.

Instructions

• 1

  Ensure all surfaces are dusted and vacuumed regularly. Household dust is a breeding ground for microscopic dust mites that feed on discarded human skin flakes. The best vacuums to use are those equipped with a high-efficiency particulate air (HEPA) filter.

• 2

  Wash fabrics regularly to prevent excessive buildup of dust mites. The washing machine must be set to at least 140 degrees to kill dust mites. Alternatively, invest in hypoallergenic replacements for curtains and bedding.

• 3

  Avoid spending large amounts of time outside in the morning, when pollen production is at its peak. Restrict flowers and outdoor plantings to low-pollen species, such as gladiolas or roses. Houseplants are prone to harboring dust and should be avoided.

• 4

  Avoid keeping pets that shed dander, a combination of dead skin cells and feathers or hair. Dander can trigger allergic reactions and asthma attacks. Consider cold-blooded alternatives that don't produce dander, such as turtles and snakes. If a dander-producing pet is already living in the home, don't allow it into bedrooms or on upholstered furniture and make sure it is washed at least once every 2 weeks. If visiting a home with pets, ask the owner to refrain from vacuuming on the day of the visit to prevent dander being stirred up.
