摘要

Climate change is likely to increase human exposure to high temperatures, leading to sleep loss. Reduced sleep duration may impair intellectual and cognitive performance, including in childhood, with potential socioeconomic impacts. Here we explore the potential global and regional economic costs of diminished childhood cognitive performance related to future climate-driven sleep erosion. Relative to the 2001–2010 baseline, excess sleep loss worldwide is projected to reach 16.37 h per year per person by the 2100s under a high-emissions scenario. Correspondingly, the associated economic costs linked to sleep erosion and potential intellectual decline are estimated to reach trillions of dollars. Less-developed regions are projected to experience greater per-capita potential intelligence quotient losses and are likely to bear several times the relative economic burden faced by the wealthiest regions, thereby probably exacerbating global environmental and economic inequalities. Our findings advance understanding of the health and economic effects of climate change and can inform fair climate policies.
