Consequences of climate change for asthma: Reviewing the evidence

The effects of climate change on human health are supported by extensive scientific evidence. There is a close association between global warming, air pollution, and asthma. Patients with asthma are particularly vulnerable to the environmental alterations associated with climate change. This review summarizes the research from the past decade (2013–2024) on how climate change influences asthma, examining its direct and indirect effects such as alterations in air quality, allergen exposure, and extreme weather events. The review highlights the complex interplay between climate change and asthma and underscores the need for integrated public health strategies to mitigate these impacts. This review also highlights the novel insights of synergistic effects between air pollutants and allergens, which are exacerbated by climate change, in worsening asthma symptoms.
