Allergy is the primary cause of asthma. Chronic exposure to dust mite allergen can cause rhinitis, eczema and the bronchial hyper-reactivity characteristic of asthma. Clinical studies have further demonstrated that in both childhood and adult asthmatics, avoidance measures resulted in decreased asthmatic symptoms and a reduction in medication requirements.
Where is Global Warming, does it help the dust mites?
Seriously, though, we've had family members with pulmonmary problems. I know this isn't funny. But dragging in the global warming BS is not helpful to finding cures and treatments.
