Q: Can teens make up for late nights by sleeping in on weekends?
A: Nope. If you do badly on an exam and your teacher gives you a do-over, all is right in the world. But sleep isn’t like a makeup test. You can certainly sleep more when you have time on the weekends, but doing so won’t erase all the negative effects caused by lack of sleep on the other five days, like having difficulty learning new concepts, remembering information and making decisions. When you don’t sleep enough, you’re also less alert, and your reaction time slows, making you more accident prone. Your body works best if you get the recommended amount of sleep every night and have a similar wake-up time every day.
