Asthma is a disease of the human respiratory system where the airways narrow, often in response to a "trigger" such as exposure to an allergen, cold air, exercise, or emotional stress. This airway narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which respond to bronchodilators.
I heard they're getting smoke in Denver. Here are some satellite photos: http://earthobservatory.nasa.gov/NaturalHazards/event.php?id=39998
Last year during the Sayre fire it was hard on asthmatics mostly because the smoke air hung around the Valley for three weeks.
I live in Oklahoma and we got smoke out here, too. Normally in summer I get a break from asthma because mine is triggered far worse with cooler/cold air. But while that smoke was in our air--whoa! was I ever coughing.
i really do feel for those that live around the brush fires and those caught down wind of it. God be with you all!
