A new study says the habit may not be such a good idea for your waistline -- or your health.
"Weekend catch-up sleep is not protective," said Dr. Vsevolod Polotsky, director of sleep research at the Johns Hopkins University School of Medicine. "The bottom line of this study is that even if you sleep longer on weekends, if you continue to sleep poorly, you will still eat too much, and you will still gain weight."
The common behavior of "sleeping in on the weekends doesn't correct the body's inability to regulate blood sugar if that weekend is followed by a workweek or school week full of insufficient sleep," said study author Kenneth Wright Jr., who directs the sleep lab at the University of Colorado in Boulder.
"And when we go back to getting too little sleep again," Wright said, "we're doing things that could be negative for our health long-term."
