Which common allergens can trigger asthma in children?

Dust mites, mold, pet dander, and pollen are well-recognized triggers for asthma in children. These allergens are commonly present in the environment and can provoke asthmatic reactions by causing inflammation and hyperreactivity in the airways.

Dust mites thrive in warm, humid environments, often residing in bedding and carpets. When disturbed, they release tiny particles that can be inhaled, triggering asthma symptoms. Mold spores, also prevalent in damp areas, can cause similar allergic responses. Pet dander, consisting of skin flakes and saliva from animals, can elicit asthma attacks in sensitized individuals. Pollen from trees, grasses, and weeds is another potent allergen that can affect children with asthma, especially during specific seasons when these plants release their pollen into the air.

Other choices listed do not primarily account for common outdoor allergens associated with asthma exacerbations. Food additives, tobacco smoke, seafood, nuts, and dairy products may cause allergic reactions or intolerance in some children but are not typically categorized as principal triggers for asthma. Heavy metals, pesticides, and solvents are more environmental hazards than common allergens, usually affecting health in other ways rather than primarily triggering asthma. Thus, the first choice encompasses the most prevalent and clinically significant allergens that can exacerbate
