The Guardian: Rising temperatures driven by global warming are cutting the sleep of people across the world, new research has found.
Good sleep is critical to health and wellbeing. But global warming is increasing night-time temperatures, even faster than in the day, making it harder to sleep. The analysis revealed that the average global citizen is already losing 44 hours of sleep a year, leading to 11 nights with less than seven hours’ sleep, a standard benchmark of sufficient sleep.
Lost sleep will increase further as the planet continues to heat but it affects some groups much more than others. The sleep loss per degree of warming is about a quarter higher for women than men, twice as high for those over 65 years old and three times higher for those in less affluent nations. The researchers used data from sleep-tracking wristbands used by 47,000 people over 7 million nights and across 68 countries.
