Sleep disturbances, mostly in women and the elderly, are caused by climate change, according to a new scientific study.
Sleep disorders (insomnia, etc.) in women and the elderly are caused by climate change, according to a new study from the University of Copenhagen, published in the One Earth review.
The increase in global temperature in the context of climate change, not only during the day, but especially at night, “breaks the sleep” of millions of people around the world. According to a Guardian article, the average citizen of the world is already losing about 44 hours of sleep a year due to rising temperatures.
Women are said to be affected more than men, which means they lose more hours of sleep, while the effects are more negative for those over 65 and those who live in less affluent and wealthy communities. environment. To make these measurements, the researchers extracted data from sleep-tracking bracelets used by 47,000 people in 68 countries.
“We spend almost a third of our lives sleeping. But more and more people in many countries around the world are sleep deprived. In this study, we present the first data in the world showing that above average temperatures can negatively affect human sleep,” said Kelton Minor from the University of Copenhagen.
According to the Guardian
