The airways in a person with asthma are very sensitive and react to a variety of external factors, or "triggers." These triggers cause the airways to tighten and become inflamed and blocked with mucus, resulting in difficulty breathing. An acute asthma attack can begin immediately after exposure to a trigger or several hours or days later.

There are many kinds of triggers, and responses to them vary from person to person. A trigger may be harmless to some asthmatics but contribute to

What is asthma?

Asthma is a disease of the bronchial tubes or airways of the lungs. Air is normally taken into the body through the nose and windpipe and into the bronchial tubes. At the end of these tubes are tiny air sacs (alveoli) that deliver fresh air (oxygen) to the blood. The air sacs also collect stale air (carbon dioxide), which is exhaled out of the body.

During normal breathing, the bands of muscle that surround the airways are relaxed and air moves freely.

What is a food allergy?

A food allergy occurs when the immune system responds defensively to a specific food protein that is not harmful to the body. When that food is first eaten, the immune system responds by creating specific IgE antibodies. When the food is eaten again, the IgE antibodies go into action, releasing large amounts of histamines, which work to expel the food protein from the body. Histamines can affect the respiratory system, gastrointestinal tract, skin, and

How do I protect my eyes while playing sports?

Americans love sports and they love to look fashionable. And we oftentimes insist that sports and fashion go together, sometimes to our own detriment. For while protective eye gear may never be the latest craze in tennis or baseball, think for a moment about the logic of not protecting our eyes. We wear helmets to protect our heads and pads and braces to protect our bones and joints, so why not take the extra step to protect our eyes?

All bike riders should wear a bicycle helmet. Each year in the United States, approximately 800 bicyclists are killed and another 500,000 end up in hospital emergency rooms. About two-thirds of the deaths and one-third of the injuries involve the head and face. Wearing a helmet can reduce the risk of head injury to bicyclists by as much as 85%.

What safety information should I look for when purchasing a helmet?

Look for the Consumer Product Safety Committee—the CPSC

Soon you will be taking your baby home from the hospital. The best way to ensure that your baby arrives home safely is to use a safe and properly installed car seat.

For many children, that will be 30, 35, or even 40 pounds. Many kids will be
