In a study exploring insomnia among adolescents, as many as one in four reported one or more symptoms of insomnia nearly every day in the previous month and nearly half of these had sleep disturbances a year later.
Researchers say the prevalence of insomnia rivals that of depression and other mental health problems. Symptoms included trouble falling asleep, waking in the middle of the night, and having trouble getting back to sleep or non-restorative sleep. They say teens need 8 to 9 hours of sleep.
