Americans may put off to the weekend catching up on sports scores, store sales, the latest news and more. But there’s a health essential that new research suggests cannot be put off for the weekend: a good night’s sleep.
The study, conducted at the University of Colorado and published in the science journal “Current Biology,” focused on a small group: three dozen healthy adults, split into three groups, with one allowed to sleep nine hours nightly, another getting just five hours of slumber, and a third with a staggered schedule. The last group, for five days, got five hours of sleep, followed by two days in which they could snooze for as long as they wished. They had to return, though, to the five-day cycle of five-hour slumbers.
Researchers followed their subjects for nine-day spans. The results will be un-welcome for proponents of weekend catch-up sleep, because it didn’t help in the ways that many of us would wish. As the Washington Post reported, those “who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced metabolic disruption that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of insufficient sleep, those gains were wiped out when people plunged right back into their same sleep-deprived schedule the next Monday.”
