People and businesses are encouraged to avoid these activities on Air Action days:

Everyone is encouraged to car pool, use their bicycles or walk, and delay or combine errands when possible. Active children and adults, and persons with respiratory diseases such as asthma, should limit prolonged outdoor exertion, the MDEQ advises.
