In brief In a global-scale natural experiment featuring over 10 billion minute-level sleep observations from sleep-tracking wristbands, we found that increases in nighttime temperature harm human sleep across nearly the entire range of observed temperatures, with sleep loss and the risk of insufficient sleep increasing steeply when nights exceed 10○C. Our findings have significant implications for international, regional, and local climate adaptation planning and illuminate a pathway by which increasing heat may unequally impact human functioning, productivity, and health globally if unmitigated climate change continues.
