• Certain infections of the respiratory system that happened during childhood.


• Coming in contact with several allergens present in the air or exposure to a number of infections caused by viruses during infancy or very early in childhood when the development of the immune system is still starting.

If it is known that atopy or asthma runs in the family, then exposure to irritants and allergens found in the air could make the airways react more to the substances that can be breathed in the air.

Allergens are pets like cats and dust house mites, while irritants could be such substances as tobacco or cigarette smoke.
