Nothing is more essential to our well-being than the ability to breathe. Most of us breathe in and out all day long without even giving it a thought. Yet millions of people in the United States are not so lucky. They suffer from asthma or allergies. For people with asthma, taking a breath can be extremely difficult. For people with allergies, the air they breathe can be filled with substances that cause discomfort or worse. Asthma is a chronic lung disease in which air passages get inflamed. When this happens, airways narrow and it is difficult for air to move from the nose and mouth to the lungs. In the United States, this disease affects millions of people, many of them children. In fact, asthma is the most common chronic childhood disease, affecting 1 out of every 20 children. The number of people with asthma has been increasing since the 1980s. The disease affects people of all ages and races and both sexes. However, asthma is more common in children than adults. It is also more common in African Americans and Hispanics than whites.
