-
Asthma is a chronic health condition characterized by inflammation of the bronchioles, the small airways in the lungs. Irritants can exacerbate symptoms of asthma, resulting in an acute asthmatic attack.
Allergens
Allergens such as dust mites, pet dander, household dust, mold and specific foods can cause acute or chronic breathing difficulties, as allergies often accompany asthma.
Exercise
Strenuous exercise can cause wheezing and lung constriction in some individuals with asthma.
Tobacco Smoke
Secondhand smoke can increase the incidence or severity of asthma attacks, and it also is believed to be a contributing factor in many new cases of asthma, according to the Environmental Protection Agency.
Weather
Those with asthma might experience an increase in severity of symptoms during times of abrupt weather change or when exposed to cold air, which can trigger airway constriction.
Bacterias and Viruses
Asthma attacks can be triggered when an individual has an infection such as the cold or flu. Asthmatic patients might have a more difficult time fighting off such common illnesses.
