Temperature extremes, climate change and multimorbidity: A rapid scoping review

Exposure to extreme temperatures disproportionally impacts vulnerable populations, including those with multimorbidity (i.e., people living with two or more long-term health conditions). A greater frequency of temperature extremes such as heatwaves driven by climate change will likely increase adverse health outcomes in vulnerable populations. Therefore, it is important to understand the potential effects of temperature extremes on the health outcomes of multimorbidity populations to aid the planning of healthcare systems and preventive interventions. In this review, evidence was collated and summarised, describing the health outcomes of extreme temperatures amongst people with multimorbidity.
