Allergy Questions and Answers

An allergy is when your immune system reacts to something that is harmless to most people. Generally, your immune system protects you from substances that can make you sick. But if you come into contact with something that your immune system views as a threat, it releases a chemical called histamine. This release of histamine and other substances is what causes allergy symptoms.

And while there’s a strong connection between allergies and asthma, there are many other triggers to be aware of, too. Some of the most common non-allergenic triggers are cold or dry air, exercise, exposure to cigarette smoke or strong scents, the flu and other respiratory infections.
