In The Best Resources For Helping Teens Learn About The Importance Of Sleep, I share research on teens and sleep and describe how I use them in my classroom).

Some new studies have just been published on the topic:

Researchers found that for each hour of lost sleep, levels of psychological distress rose by 5% in nearly 3,000 17-to-24-year-olds who were followed for 12 to 18 months. Overall, short sleepers were 14% more likely to report symptoms of psychological distress on a standard test, compared with people who got adequate sleep.

…teens who didn’t get enough z’s consumed more calories than their well-rested peers. The study of 240 adolescents, average age 18, revealed that teenagers who slept less than 8 hours a night on weeknights ate 2% more calories from fat per day and 3% more calories from carbs than teens who slept longer. They also tended to get their calories from snacks instead of healthful meals. Cumulatively, this behavior increases the risk of obesity and, in turn, the chances of developing cardiovascular disease later in life.
