A massive survey on sleep confirms what many already know about the topic, so there’s probably no excuse for those extra hours of Netflix you might clock in each night.
Picked up by Inc., a year-long analysis by neuroscientists from Western University’s Brain and Mind Institute that observed the sleep patterns of 44,000 global participants also proves that too much sleep isn’t good for you.
Billed as the “world’s largest sleep study,” the research, which started in June 2017, involved a series of tests including an in-depth questionnaire and cognitive performance exercises.
The verdict might be something you have suspected—and tried to disprove—all along: the optimal amount of shut-eye turns out to be seven to eight hours.
“We found that the optimum amount of sleep to keep your brain performing its best is seven to eight hours every night and that corresponds to what the doctors will tell you need to keep your body in tip-top shape,” Conor Wild, Owen Lab Research Associate and the study’s lead author, detailed.
Here’s the bit that might surprise you even more: the cognitive performances of those who slept more than eight hours were “equally impaired” as the people who under-slept.
About half of the 44,000 participants admitted to sleeping under 6.3 hours per night.
Startlingly, those who slept four hours or less “performed as if they were almost nine years older,” the institute found, so accrue those sleep hours if you want to perform at your creative best.
