The negative health effects of skimping on sleep during the week can’t be reversed by marathon weekend sleep sessions, according to sobering new study.
【小题1】 complete freedom to sleep in and nap during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays 【小题2】 (gain) nearly three pounds over two weeks and experienced metabolic disorder 【小题3】 would increase their risk for diabetes over the long term. 【小题4】 weekend recovery sleep had some benefits after a single week of insufficient sleep, those gains 【小题5】 (wipe) out when people plunged right back into the same schedule 【小题6】 (rob) of sleep the next Monday.
“If there are benefits of catch-up sleep, 【小题7】 are gone when you go back to your routine. It’s very short-lived.” said Kenneth Wright, director of the sleep and chronobiology laboratory at the University of Colorado at Boulder, who oversaw the work.
