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 infections of the respiratory system.

BOB DOUGHTY: The Centers for Disease Control and Prevention says more than twenty-five million people in the United States have asthma. It says the disorder affects more than seven million American children. Among adults, more women have the disease than men. However, it is more common among boys than girls.
The National Institute of Allergy 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.
SHIRLEY GRIFFITH: VOA Special English broadcaster June Simms has a fifteen-year old son with asthma. Arick Simms first showed signs of the disease when he was about two years old.
Arick's doctor gave him a medicine called albuterol. Albuterol helps to increase air flow and reduce tension in the airways. The doctor also gave him a machine called a nebulizer. It connects to a mask that fits over the nose and mouth.
The nebulizer turns the liquid albuterol into a fog-like mist. Arick inhaled the mist through the mask. The treatments made it easier for him to breathe. During times when Arick's asthma was really severe, he was also given steroid medicines to help reduce swelling in his airways.
