Walking, jogging or cycling outdoors can increase the amount of polluted air you inhale, as physical activity makes you breathe faster and deeper.

Children's lungs are still developing and can be particularly vulnerable to air pollution. Limit play outside, sports and other strenuous activities in parks and playgrounds.

High traffic volume roads and intersections can be sources of exposure to emissions and dust and other pollutants. Minimize exposure to other people when exiting to the outdoors, if needed, to choose less crowded ways whenever possible.

Dust and fine particulate matter may be released to the air during the construction and demolition activities. Avoid going near such places whenever the dust-control measures are not satisfactory.

Do not attend long hours of outdoor picnics, sporting events, social events and recreational events. If you need to go outside, try to go to a place that is free of polluted air.

A well-fitted respirator that filters at least 95% efficiency (N95 or higher) should be worn if going outside is not avoided. Make sure that it fits snugly over the nose and mouth with as few gaps as possible around the sides.

Avoid early morning exercise outdoors because it is not always safer. Monitor and monitor AQI before going outdoors, and limit outdoor physical activity during periods of high pollution.

Reduce unnecessary trips, errands and extended periods outdoors. Make sure all trips are carefully planned and spend as little time as possible in polluted environments.
