What are common triggers for asthma exacerbations in children?

The selected answer identifies common triggers for asthma exacerbations in children, highlighting allergens, respiratory infections, and exercise.

Allergens such as pollen, dust mites, molds, and pet dander are well-known triggers for asthma in kids. When children with asthma are exposed to these substances, their immune system can overreact, leading to inflammation and airway constriction.

Respiratory infections, particularly viral infections like the common cold, can also exacerbate asthma. Children are particularly susceptible to these infections, which can lead to increased inflammation and mucus production in the airways, worsening asthma symptoms.

Exercise is another common trigger for asthma exacerbations, particularly in children with exercise-induced bronchoconstriction. Physical activity can lead to narrowing of the airways in some children, especially in cold or dry air.

In contrast, the other answer choices contain factors that, while they can influence overall health or well-being, are not established triggers for asthma exacerbations. Cold weather may be uncomfortable for children with asthma but is not a direct trigger. Bright lights and stress can affect overall health, while lack of sleep might influence the severity of asthma symptoms rather than trigger an exacerbation. Increased hydration and diet changes do not directly relate to asthma triggers; rather, maintaining overall
