Allergens such as mold, pollen or animals, irritants like cigarette smoke or air pollution can all be triggers. Weather such as old air or even sudden changes in the weather can also cause an attack. Exercise is another trigger for an asthma attack. If a child has airway hyper reactivity this is another risk factor for asthma. However not all people who have airway hyper reactivity develop asthma, but if one does have it they have a greater chance of developing asthma.

Atopy may include eczema, allergic rhinitis or allergic conjunctivitis. There have been studies done that indicate that 40-50% of children with eczema develop asthma. Indoor air pollutants are a large factor in asthma. Some...
