Climate change and allergic diseases: A comprehensive review of current evidence and future implications

Abstract Climate change is increasingly recognized as a significant threat to public health, with mounting evidence suggesting its profound impact on allergic diseases. This comprehensive review discusses the intricate relationship between climate change and allergic conditions, focusing on allergic rhinitis, asthma, and atopic dermatitis. We synthesize current research on how climate-induced alterations in temperature, precipitation patterns, and atmospheric composition affect the production, distribution, and allergenicity of aeroallergens. Furthermore, we explore the mechanisms by which these changes influence the prevalence, severity, and phenotypes of allergic diseases. The review also discusses the broader public health implications, including the economic burden and impact on quality of life. Finally, we present potential mitigation strategies and areas for future research, emphasizing the need for interdisciplinary approaches to address this growing global health concern.
