Allergens.
Exposure to allergens is a trigger for symptoms in sensitized individuals with asthma. This is especially true for allergens primarily found indoors but can be true for outdoor allergens with sufficiently high exposure. The role of allergens in attacks can be subtle in that they provide the underlying inflammation necessary for other nonspecific agents to have an effect.
