Global warming impacts sleep, study finds

Rising temperatures around the world would cause humans to lose 44 hours of sleep each year – while the number may not be significant spread over 365 days, it does show the direct impact of global warming on our sleep and possible issues that may crop up if the temperatures continue to rise unabated.

Climate emergency may well have a direct impact on the behavior of individuals and this trend is expected to intensify in the years to come. As reported in a study cited in The Guardian and spotted by Courrier international , the rise in temperatures caused by global warming would, on its own, reduce the sleep of people around the world.

According to the scientists’ results, humans already lose an average of 44 hours of sleep per year, which represents 11 nights with less than 7 hours of sleep, due to global warming. But, with their predictions, we could each lose between 50 and 58 hours of sleep per year by the end of the century, if major maneuvers are not put in place internationally to stem the rise in temperatures.

The authors of the study, who analyzed the sleep of 47,000 adults from 68 different countries, also found that a very hot night, when the thermometer showed more than 30 degrees, caused the average person to lose 14 minutes of sleep. an adult. They also point out that the impact of global warming on sleep will be significantly greater for people in low-income countries, as well as for the elderly and women.

Another worrying finding from this study, the data showed no signs of humans being able to adapt to warmer nights. “For most of us, sleep is a very familiar part of our daily routine; we spend nearly a third of our lives sleeping,” says Kelton Minor of the University of Copenhagen, who led the study. “A growing number of people in many countries around the world do not get enough sleep and will sleep less and less,” he also warns.
