Caffeine, Technology Affecting Teens' Ability to Stay Alert

June 2, 2009

The use of nighttime media-related technology and a reliance on caffeinated beverages are affecting teens' ability to stay alert and fully functional throughout the day, according to a study in the journal Pediatrics. Researchers asked subjects, middle and high school students aged 12 to 18 years old from a suburb of Philadelphia, about their sleep behavior, technology use and caffeine intake. According to the study, one-third of the students reported falling asleep during school and caffeine consumption among students who fell asleep was 76 percent higher. Teens typically need about 9 1/4 hours of sleep each night to function best; although for some, 8 1/2 hours is enough. Here's a little advice for teens out there: Try to avoid the TV, computer and telephone in the hour before you go to bed. Stick to quiet, calm activities, and you’ll fall asleep much more easily!
