Why do such things as perfumes, strong odors, and aerosol sprays seem to cause increased allergy or asthma symptoms?
Most people with allergies and/or asthma have unusually sensitive airways. Factors that may cause only mild irritation in non-allergic people can cause a great deal of aggravation and discomfort in those with allergies or asthma, and can actually reproduce their symptoms. Avoidance of these irritants is the best treatment, but good control of the underlying allergy may improve tolerance.
