Sleep is very important in daily life, since it has great impact in physical and psychological development of young people, and influences the behavior and learning (Valle, 2009).
Considering that, the Brazilian Sleep Association states that teenagers “have more difficulty anticipating sleep and waking hours to adapt to morning school class, especially those starting before eight o'clock”.They also point out that sleep restriction is associated with health problems, and affects academic performance “by increasing sleepiness, reducing attention and learning readiness, which also compromises memory consolidation”(ABS, 2017).

The study was conducted from April 2018 to August 2019. After literature review, 148 students from the first to the third year of high school from a private school in São Caetano do Sul, were analyzed through the Pittsburgh Scale, Epworth Sleepiness Scale, and the SF-36 Quality of Life Questionnaire, as well as other informations such as their age and gender. Results were tabulated and statistically analyzed.

Moreover, 13,51% of students feel tired all the time, 23,65% feel tired most of the time, 22,29% feel tired currently, and only 3,37% never feel tired. Still, 52,7% feel very nervous during “most of the time” and “all the time”, and 30,4% feel discouraged and downcast during “most of the time” and “all the time”.
All students stay in school from 7:20 am to 1:00 pm, and it's seen that 98,65% of them go to bed after 22 pm, what suggests that adolescents sleeping habits and morning classes are related.
