Air pollution, climate change, and the decrease of biological diversity are major threats to human health. In the past decades, an increase in allergic diseases, including asthma and rhinoconjunctivitis, has been observed. Up to 40 % of the world population may have an allergic disease, which represents a significant impact on the quality of life of those who suffer from it, and environmental pollution is one of the causes of its presentation. Air pollution causes significant morbidity and mortality in patients with inflammatory airway diseases such as allergic rhinitis, chronic rhinosinusitis, asthma, and chronic obstructive pulmonary disease. Oxidative stress in patients with respiratory diseases can induce eosinophilic inflammation in the airways, increase atopic allergic sensitization, and rise susceptibility to infections. Climate change has influenced exposure to extramural allergens and it is associated with exacerbations of respiratory diseases in the upper and lower airway. The interaction of indoor and outdoor environmental exposure and host factors can affect the development and progression of lifelong allergic diseases. The decrease of exposure to air pollutants has been associated with a favorable response in respiratory health, which is why it is necessary to implement measures that contribute to an improvement in air quality.
