Triggers for asthma symptoms can vary widely among individuals and may include allergens such as pollen, dust mites, pet dander, as well as respiratory infections, air pollution, exercise, and cold air.The hallmark feature of asthma is airway inflammation, which causes the lining of the airways to become swollen and produce excess mucus.
