Air pollution can also trigger asthma. Cigarette smoke is a major problem for asthma sufferers. So is air pollution from motor vehicles. Chemical sprays like air fresheners, hair spray, cleaning products and even strong beauty aids can trigger an asthma attack.
Some people cough, wheeze or feel out of breath during or after exercise. They are said to suffer from exercise-induced asthma. During the winter, breathing in cold air can trigger an asthma attack. So can colds and other respiratory infections.
VOICE ONE:
The Centers for Disease Control and Prevention says more than twenty-three million people in the United States have asthma. Among adults, more women have the disease than men.
Asthma affects more than seven million children each year. It is more common among boys than girls.
The National Institute of Allergies and Infectious Diseases says the disease affects African-Americans more than whites. African-American children die from asthma at five times the rate of white children.

VOICE TWO:
Special English reporter June Simms has a fourteen-year old son with asthma. Arick first showed signs of the disease when he was about two years old.
The doctor gave Arick a medicine called albuterol. Albuterol helps to increase air flow and reduce tension in the airways. The doctor also gave Arick a machine called a nebulizer. It connects to a mask that he placed over his mouth and nose.
