Facilities should be provided for families to become aware of the quality of the air year round and to check daily air-quality levels and air-pollution forecasts by mass media, local weather reports and other available public information sources. This is especially important for smog levels during hot weather. Protective measures should be taken into account for children and pregnant women to reduce their exposure to air pollutants, e.g. children and pregnant women should avoid congested streets and rush hour traffic, and families should try to limit the amount of time their child spends outdoors in vigorous activity if the air quality is unhealthy.
