Airborne substances are the single most common cause of allergic reactions. In addition to provoking respiratory allergic symptoms in children—mainly seasonal or chronic hay fever or asthma—they may intensify complaints like eczema, and they are often linked to other problems, such as chronic earache, itchy, teary eyes, and gastrointestinal difficulties. The symptoms follow a period of sensitization and are uncommon in children before the age of 4.
