Furthermore, teachers with high demand and with different work schedule, which may contribute to changes in SWC. The aim of this study was to describe the SWC of high school teachers in Natal/RN. Habits and knowledge about sleep, chronotype, SWC, daytime sleepiness, sleep quality and job satisfaction were described in 98 high school teachers from public and private school. These parameters were compared according to the characteristics of work, family structure and gender. Data collection was performed with the use of questionnaires in two stages: 1) "health and sleep" (general characterization of sleep habits), Horne & Ostberg questionnaire (characterization of chronotype), Epworth Sleepiness Scale and the Index of Pittsburg Sleep Quality, 2) The sleep diary for 14 days. From the results, we observe that the teachers woke up and went to bed earlier in the week and showed a reduction of time in bed around 42min comparing to weekend. This reduction in time in bed during the week was accompanied by an increase in nap duration on weekend. In addition the teachers woke up earlier on Saturdays than on Sundays, probably due to housework and leisure. The teachers' knowledge about sleep was low in relation to individual differences and effect of alcoholic beverages on sleep, and high in the consequences of sleep deprivation. The differences found in comparisons on the characteristics of work, family structure and gender were punctual, except concerning the work schedule. The teacher who started work in the morning and finished in the night, woke up earlier, went to bed later and had less time in bed, when compared to teachers who work only in two shifts. In addition, teachers with late chronotypes who begin the work in the morning had a greater irregularity in the wake up time compared to teachers with earlier and intermediate chronotypes. Half of teachers have excessive sleepiness, which was positive correlated with work dissatisfaction. In general, teachers showed IPSQ averages equivalent to poor sleep quality and the women showed worst averages. From the results, it is suggested that the SWC of teachers varies according to work schedule, leading to irregularity and partial sleep deprivation in the week, although these responses vary according to chronotype. These changes are accompanied by excessive daytime sleepiness and poor sleep quality. However, it is necessary to expand the sample to clarify the influence of variables related to work, family structure and gender together / No ambiente escolar ? de fundamental import?ncia o conhecimento sobre o ciclo sono e vig?lia (CSV), pois encontramos crian?as e adolescentes com sonol?ncia excessiva e dificuldades de aprendizagem, al?m de professores com alta demanda e hor?rio diferenciado de trabalho, o que pode contribuir para o surgimento de altera??es no CSV. O objetivo deste estudo foi caracterizar o CSV de professores do ensino m?dio de Natal/RN. Participaram da pesquisa 98 professores de escolas p?blicas e privadas, dos quais, foram descritos os h?bitos e conhecimentos sobre o sono, cronotipo, padr?o do CSV, n?veis de sonol?ncia diurna, qualidade do sono e satisfa??o profissional, comparando estas vari?veis quanto ?s caracter?sticas de trabalho, estrutura familiar e g?nero. A coleta de dados foi realizada com a aplica??o de question?rios em duas etapas: 1) sa?de e o sono (caracteriza??o geral dos h?bitos de sono); question?rio de Horne & Ostberg (caracteriza??o do cronotipo); Escala de Sonol?ncia de Epworth e o ?ndice de Qualidade do Sono de Pittsburg; 2) O di?rio de sono durante 14 dias. A partir dos resultados, observamos que os professores levantaram e deitaram mais cedo e apresentaram uma redu??o do tempo na cama em torno de 42min na semana quando comparada ao fim de semana. Esta redu??o no tempo na cama na semana foi acompanhada por uma maior dura??o do cochilo no fim de semana. Al?m disso, os professores levantaram aos s?bados mais cedo que aos domingos, provavelmente devido aos afazeres dom?sticos e lazer. O conhecimento dos professores sobre o sono foi baixo com rela??o ?s diferen?as individuais e o efeito de bebidas alco?licas sobre o sono e alto em rela??o ?s consequ?ncias da priva??o do sono. As diferen?as encontradas nas compara??es quanto ?s caracter?sticas de trabalho, estrutura familiar e g?nero foram pontuais, exceto com rela??o ao hor?rio de trabalho. Os professores que iniciavam o trabalho pela manh? e finalizavam ? noite levantaram mais cedo, dormiram mais tarde e apresentaram menor tempo na cama, em rela??o aos que trabalhavam apenas em dois turnos. Al?m disso, entre os professores que iniciavam o trabalho pela manh? e que foram classificados como vespertinos houve uma maior irregularidade no hor?rio de levantar em rela??o aos matutinos e intermedi?rios. Metade dos professores apresentou sonol?ncia excessiva, que teve correla??o positiva com a insatisfa??o com o trabalho. Em geral, os professores apresentaram m?dias do IQSP equivalentes ? m? qualidade de sono, tendo as mulheres piores m?dias. A partir dos resultados, sugere-se que o CSV dos professores varia de acordo com o hor?rio de trabalho, acarretando em irregularidade no CSV e priva??o de sono durante a semana, embora o efeito sobre irregularidade varie em fun??o do cronotipo. Estas altera??es s?o acompanhadas de sonol?ncia excessiva diurna e m? qualidade de sono. Por?m, faz-se necess?rio ampliar a amostra para esclarecer a influ?ncia das vari?veis relacionadas ao trabalho, ? estrutura familiar e g?nero em conjunto
