Have you ever seen a sunrise or a rainbow or a work of art so beautiful that it seemed to take your breath away? Such a “breathless” feeling is usually in your mind due to excitement.For millions of Americans, though, breathlessness is a feeling they feel — physically — all too often, and it’s not at all enjoyable.
What is Asthma actually ?
Asthma (pronounced az-muh) is a long-term disease of the lungs that causes inflammation and narrowing of the airways. When this happens, people may experience tightness in their chests, shortness of breath, and coughing.
Asthma affects both the young and the old
Although it usually starts in childhood. In the United States, doctors estimate more than 25 million people have asthma and about 7 million are children.Your airways (also called your “breathing tubes” or “bronchial tubes”) carry oxygen from the air through the windpipe (also called the “trachea“) to your lungs. Many people take breathing for granted. It’s simply automatic.
Symptoms and cause
For people with asthma, though, breathing can sometimes be difficult because their airways are very sensitive. No one knows for sure why some people’s airways are more sensitive than others’, but doctors do believe asthma tends to run in families.
So if you have asthma, you may have gotten it because of your family’s genetic history. It’s not like a cold, though.Asthma is not contagious and can’t be “caught” through the air. You’re either born with sensitive airways, or you’re not.
