Researchers now see sleep problems as a cause, and not a side effect, of teenage. All in all, the current article represents an important but early step in our exploration of the relationship between sleep, brain development, and behavior in adolescence. Given that one-third of our lives are spent asleep and that the amount and quality of sleep has profound impact on our health, cognition, and behavior, it seems prudent to devote more resources to research this understudied. In making inside the teenage brain, we seemed to hit a nerve -- a parental one -- when we began looking into the world of teenagers and how they sleep. many physical changes are happening during the teen years, including rapid gains in height and weight, hormonal influences, the development of secondary sex characteristics and continued brain. good, plentiful sleep is essential to teens development, growth, and quality of life.

Inadequate sleep is endemic in adolescence (colrin & baker, 2011). In addition to receiving less than optimal average sleep per night, variability in sleep duration and sleep-wake rhythms peak during adolescence (dahl & lewin, 2002 thorleifsdottir et al. Children and adolescents often need more sleep than adults, which is attributed to the putative function sleep serves in brain.).
