In recent decades, the prevalence of allergic respiratory diseases, such as asthma and allergic rhinitis, in children has been rising at an alarming rate. One of the key contributors to this trend is climate change, which has altered environmental conditions, exacerbating the frequency and intensity of allergens such as pollen, mold, and air pollutants. This paper examines the dynamics of the increasing incidence of allergic respiratory diseases in children under the conditions of climate change. It explores the key environmental factors-such as rising temperatures, longer pollen seasons, and worsening air quality-that contribute to this growing health concern. The paper also delves into the vulnerability of children, whose developing immune and respiratory systems make them more susceptible to environmental stressors. In addition, it emphasizes the importance of preventive measures, including environmental regulation, early detection, allergen avoidance strategies, and public health policies aimed at reducing exposure to harmful environmental factors.
