It is important to know what things make your asthma worse. These are called asthma "triggers." Avoiding them is your first step toward feeling better. The most common asthma triggers are respiratory tract infections caused by viruses, such as the flu and common cold. Other triggers are cold and dry air, mold, pets, dust, grasses, pollen, cockroaches, odors from chemicals, and smoke from cigarettes.
