If you are allergic to dust mites, make sure your living space is kept clean. Acaricides are sprinkled on carpets and upholstered furniture, allowed to act, and then vacuumed up. If you are allergic to animal dander and have pets, keep them outside your house. If this is not possible, don t let them into your bedroom. If mold triggers your allergies, use kitchen and bathroom exhaust fans and dehumidifiers elsewhere in the house to keep the humidity inside your home low.
High humidity allows mold to grow.
Piles of newspapers can harbor mold, so recycle them promptly. No matter what triggers your nasal allergy, avoid being around tobacco smoke. Tobacco smoke may irritate the lining of your nose, increases your risk of infection, and may make your symptoms worse. If you smoke, try to quit. If other members of your family smoke, ask them to stop or to smoke only outdoors.
