Eco-anxiety

Eco-anxiety is already causing people to lose sleep over climate change. Now, a global study has found that a warming planet is also [blank] how long people sleep, and the problem will get significantly worse this century even if humanity manages to rein in its carbon emissions. Our measurements of the [blank] of above-average night temperatures on sleep have previously been limited by being confined to single countries, lab studies or notoriously unreliable self-reporting of sleep. To glean a better real-world picture, Kelton Minor at the University of Copenhagen, Denmark, took data from sleep-tracking wristbands used by 48,000 people in 68 countries between 2015 and 2017. He and his colleagues then [blank] the sleep data with local weather data, revealing that unusually hot nights are causing people to fall asleep later, rise earlier and sleep less.
