Teens and Sleep

Another reason to set bedtimes for your teens: Not getting enough sleep can make them crave fatty food and put them at risk for obesity.

If your teens like to pull "all-nighters", here’s another reason to send them to bed: Sleeping fewer than eight hours a night can mess with their metabolism and stimulate their appetite.

According to a study in the journal Sleep, "sleep-deprived teens not only eat more calories than those who get enough shut-eye", they also eat fattier foods. Teens need a good nine hours of sleep each night to feel rested and alert. Since adolescents are wired to stay up late, let them sleep in on weekends.
