In case you think I’m kidding about going to bed early tonight, here are a few links about the importance of adolescents getting sufficient sleep. For example this, from PBS:
In experiments done at Harvard Medical School and Trent University in Canada, students go through a battery of tests and then sleep various lengths of time to determine how sleep affects learning. What these tests show is that the brain consolidates and practices what is learned during the day after the students (or adults, for that matter) go to sleep.
Here’s another one from NPR, and one from the National Sleep Foundation.
