The aim is to reduce exposure to the allergen (1).
General measures include:
- humidity control—some people claim that many symptoms of rhinitis improve with humidifiers. However, they may be a source of allergens, such as moulds, and may promote the growth of mites
- avoidance of irritants such as cigarette smoke, ammonia, soap powder
Specific measures are dictated by the identification of particular allergens. These may include:
- removal of household pets
- removal of sources of feathers—pillows, birds, down jackets
- minimise carpeting—carpets may act as a reservoir for dust, mites, dander
- isolate bedroom from hot air heating systems, which may introduce allergens through the air ducts
- although dust mites are common allergens in allergic rhinitis, studies have not confirmed any benefit to using mite-proof impermeable mattresses or pillow covers (2)
- launder pillows and bedding regularly in hot water
- keep windows closed during pollen season (3)
- use air conditioning in bedroom and car
