The impact of rising ambient temperatures on the mental and physical health of children

Globally, mean ambient temperatures have increased by 1.6 °C between preindustrial level and 2024, alongside a rise in extreme weather events such as heatwaves and droughts. This rapid review synthesizes the existing literature on the risks to children’s physical and mental health due to heat exposure. Comprehensive literature searches were conducted using PubMed, Scopus, Web of Science, and ScienceDirect. This review highlights the increased risks to children’s physical and mental health from extreme temperatures in several populations. Major health concerns include heat-related illnesses, dehydration, increasing incidence of infectious diseases, reduced cognitive performance, depression and anxiety and the exacerbation of pre-existing conditions. Potential strategies to mitigate these negative health outcomes are proposed, including improved access to cooling solutions, public health interventions, and educational campaigns to improve thermal comfort.
