According to the U.S. Centers for Disease Control and Prevention, the number of asthma cases has doubled in the U.S. since 1980, and 1 in 10 children are now affected.

Asthma is a chronic lung disease that causes shortness of breath and wheezing due to inflamed and swollen airways. Certain inhaled substances can trigger episodes of inflammation, known as asthma attacks.

Sometimes asthma flare-ups are mild and go away with time or after minimal treatment with asthma medicine. Other times, sever attacks can be fatal if emergency care is not delivered.

Asthma typically develops during childhood, and it is the most prevalent chronic childhood disease, according to the Asthma and Allergy Foundation of America. It also is the leading case of school absenteeism, as well as child hospitalizations and emergency room visits.

Air pollution is generally considered the main culprit for the increasing number and severity of asthma cases. Emissions from coal-fired power plants, boilers and car tailpipes can trigger asthma attacks, particularly in young children and the elderly.

In addition, some researchers believe higher carbon dioxide levels in the atmosphere are responsible for record high pollen counts in springtime that cause dangerous conditions for asthma and allergies.
