TAMPA, Fla. (FOX 13) - If you like hitting the snooze button on weekends to catch up on lost sleep, you may need to think again, according to a new study.
The study by the journal Current Biology found those extra hours in bed won’t make much a different in your body. The extra sleep actually ends up hurting you in the long run. Researchers found weekday sleep loss had negative effects on a person's metabolism. An attempt to catch-up on sleep during the weekends did not reverse those effects.
Researchers took 36 healthy young adults and split them into three groups. One group was allowed to sleep for up to nine hours each night, and the second group could only sleep for five hours.
The third group was allowed five hours of sleep for five days. With a weekend recovery period where they could sleep as late as they wanted before returning to five hours for two nights, the study found those who were sleep-deprived snacked more at night and gained weight.
People who slept in on weekends saw mild improvements to their health, but eventually slipped back into bad eating habits that negatively affected their metabolism.
To combat sleep deprivation, the American Academy of Sleep Medicine recommends at least seven hours of sleep each night for adults. Children are expected to sleep even longer.
