Can a person get asthma from environmental exposure?

Can trigger. Certain elements in the environment can trigger an asthma exacerbation in someone who is predisposed or has asthma. But they do not "give" asthma to someone.
Generally yes. One must have asthma or a tendency for asthma. Environmental allergies can trigger asthma , such as pollen, dust mites, and pet exposure. Non allergic triggers could be cold air, respiratory tract infections, air pollutants including cigarette smoke.
