Narrator: This is Science Today. Insomnia is as prevalent in teenagers as anxiety and mood disorders. Allison Harvey, director of the Sleep and Psychological Disorders Laboratory at the University of California, Berkeley, says sleep need during the teenage years is probably much greater than during adulthood because there's so much development going on.
Harvey: To do all that brain and body development that is happening during puberty, sleep is critical for that - critical for brain plasticity, critical for all of those aspects of development. Yet, teenager's lives are often not set to get the amount sleep that they really need.
Narrator: Harvey says teens probably need more than the average eight hours.
Harvey: In teenagers, one of the major ways that we start working with their sleep is to try and get them to regulate their sleep-wake schedule. When you look at the time to bed and the time to wake up on weekdays versus the weekends, there's a huge discrepancy.
Narrator: The key thing is, getting up about the same time every morning or at least within a two hour window. For Science Today, I'm Larissa Branin.
