[The potential effect mechanism and research progress of extreme temperature exposure on asthma attacks]

Asthma is one of the common chronic respiratory diseases, and its incidence has been increasing worldwide in recent years. In the context of climate change, the frequency and intensity of extreme weather events are increasing. A large body of evidence suggests that exposure to extreme temperatures can increase the risk of asthma attacks, but the underlying mechanisms that trigger asthma attacks are still unclear. This study aims to systematically review the research progress on the association between extreme temperature and asthma attacks, and to elucidate the synergistic effects of extreme temperatures, indoor/outdoor environments, and individual vulnerabilities on asthma attacks. Additionally, this review discusses the potential mechanisms of asthma attacks triggered by extreme temperature, and highlights the important role of immune regulation and neuroregulation in the inflammatory response of asthma induced by extreme temperature. Moreover, we propose a potential mechanism framework to explain the disease pathogenesis of asthma which is induced by the interactions between extreme temperature and environmental factors, in order to provide a scientific basis for addressing the adverse impacts of extreme weather events and climate change.
