Sleep problems in adolescents are not rare and can cause aggression, inattention and behavioral disorders. This study investigated the sleep habits and sleep problems of adolescents in Kırıkkale province. Of 1807 students from two high schools and five elementary schools, with a mean age of 15.1±1.61 years, 60.8% had no sleep problems, 17.2% had difficulty falling asleep, 12.7% had difficulty waking up in the morning, and 9.3% woke up frequently for no reason. Among all, 30.8% stated that they went to bed at 10:00-11:00 p.m., and mean duration of sleep was determined as 8.77±1.37 hours. Those who were exposed to domestic violence, who had a family member with an alcohol problem and who were smokers reported more sleep problems. In contrast, those with regular rituals before sleep, academic success, and who regularly played sports/exercised experienced fewer problems. To decrease sleep problems, teenagers should be recommended to undertake physical exercise, to get sufficient sleep at night, and to adopt habits before going to bed that facilitate falling asleep.
