No, children and teens are not too young to develop sleep disorders. In fact, we are seeing sleep disorders in teens in alarming proportions. A recent study published in the journal Sleep examined insomnia in adolescents 11 to 17 years of age. The study found that one in four youths reported one or more symptoms of insomnia every day for a month. When studied a year later, more than a third of those respondents reported additional medical symptoms. Emergence of fatigue and sleepiness suggests progression of this condition.
