Eco-anxiety is already causing people to lose sleep over climate change. Now, a global study has found that a warming planet is also affecting how long people sleep, and the problem will get significantly worse this century even if humanity manages to joinreingainvein rein in its carbon emissions. Our measurements of the impact of above-average night temperatures on sleep have previously been limited by being decidedexpectedrequiredconfined 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 containedcontrolledpairedaccessed paired the sleep data with local weather data, revealing that unusually hot nights are causing people to fall asleep later, rise earlier and sleep less.
