Sleep is a basic need that influences, and is influenced simultaneously, by the diversity of life activities, roles and contexts, assuming particular importance in adolescents. A study was developed with 400 students in 9^th and 11^th school years, of two schools in the Lisbon, assessed by the Questionnaire about Sleep for Adolescents. The quantitative results focused on sleep habits, self-perceptions and knowledge. From the qualitative exploration of the factors cited by 100 adolescents as a reason of their self-perceptions, emerged the categories of quality, relevance and attitudes. Based on these results we propose a three-dimensional model about sleep that addresses sleep habits, personal factors and environmental factors.
