Indoor and
Outdoor Air Quality
Air pollution has well documented effects on acute respiratory exacerbations as well as
acute cardiovascular events. There is emerging evidence on the effects of chronic exposure
to pollutants on the development and maintenance of lung function and the development in
some instances of asthmatic symptoms. Control of exposure is largely through control of
sources of emissions including domestic heating, traffic and industrial sources. Other
important considerations include the ventilation of homes. |
Indoor and Outdoor Air
Quality
Exposure of vulnerable groups is difficult without overall control of the environment.
Some particular exposures may be controlled independently such as domestic and
occupational sources, and exercise can be reduced at times of high pollution. |
Allergen
Avoidance
There is a link between mite and cockroach allergen exposure and asthma. The potential of
allergen reduction in the management of asthma is suggested by studies in the low-allergen
environment of hospitals or high-altitude sanatoria. However, a conclusive answer on the
feasibility and effectiveness of low cost domestic aeroallergen avoidance in asthma is
unclear yet. |
