Non medicine treatment for asthma attacks

Medical English: What People With Asthma Can Do to Keep It Under Control.

This is Science in the news in Special English. And I'm Bob Doughty.

We recently told you about health problems linked to extreme heat. This week, we talk about the lung disease asthma. For people with asthma, extreme heat can be especially troublesome, as can extreme cold.

Asthma is a serious disorder that makes breathing difficult. The World Health Organization says asthma affects about three hundred million people worldwide. An estimated two hundred fifty thousand people die from the disease every year.

And more than five hundred thousand others are treated in hospitals. Asthma happens when tissue that lines the airways to the lungs begins to expand or swell.

This swelling clinic makes the airways smaller. The muscles in the airways tighten.

Cells in the airways begin to produce a lot of mucous. This thick, sticky substance causes the airways to close even more. This makes it difficult for air to flow in and out of the lungs.

This series of events is called an asthma attack. As asthma sufferers struggle to get air into their lungs, they may begin to cough a lot. They may also make a whistling or breathy asthma sound called wheezing.

Some asthma sufferers have tightness or pain in the chest. They say it feels as if someone is sitting on them.
