BALTIMORE — Excessive cell phone use during the day can mean restless nights and disturbed sleep for teenagers and young adults, new research suggests.
Teens who get more than 15 calls or text messages each day are more restless, consume more caffeine and alcohol, have more trouble falling asleep and staying asleep and are more susceptible to stress and fatigue than young people who receive five or fewer calls or text messages each day, shows a study presented Monday at SLEEP 2008, the annual meeting of the Associated Professional Sleep Societies.
