ABSTRACT
Abstract The influence of a sleep education program (SEP) on the knowledge, habits, quality of sleep, and daytime sleepiness was evaluated in 40 Brazilian elementary and high school teachers [Groups: Experimental (EG=26)/Control (CG=14)]. The Health and Sleep questionnaire, Pittsburgh Sleep Quality Index and sleep logs were applied to both groups, at baseline and in reassessment three weeks after a SEP with the EG. The methodology of the SEP was based on the Meaningful Learning theory proposed by Ausubel, consisting of four fortnightly meetings, lasting 4h each. After the program, the EG showed an increase in sleep knowledge and a reduction in coffee consumption near bedtime. Besides, 17% of teachers improved sleep quality in this group. However, no changes occurred in sleep schedules and sleepiness. Nevertheless, the positive results reinforce the need for sleep education programs with teachers to spread sleep knowledge in schools and improve the sleep quality in these professionals.
Resumo A influência de um programa de educação sobre o sono (PES) nos conhecimentos, hábitos e qualidade do sono, e sonolência diurna foi avaliada em 40 professores brasileiros do ensino básico [Grupos: Experimental (GE=26)/Controle (GC=14)]. A Saúde e Sono, o Índice de Qualidade de Sono de Pittsburgh e o diário de sono foram aplicados nos grupos antes e três semanas após um PES aplicado no GE. O programa baseado na teoria da Aprendizagem Significativa consistiu de quatro encontros de 4h/cada. Após o programa, o GE aumentou os conhecimentos sobre sono e reduziu o relato de consumo de café próximo a dormir, com melhora na qualidade de sono em 17% dos professores. Embora não tenha havido diferenças nos horários de sono e sonolência, os resultados positivos reforçam a necessidade do desenvolvimento de programas educacionais sobre sono com professores para difusão do assunto nas escolas e melhora da qualidade do sono nestes profissionais.

The influence of work schedule on sleep habits and quality, and daytime sleepiness according to individual preferences in sleep schedules was assessed in 131 elementary and high school teachers through questionnaires. Teachers who initiate classes around 7:00 hr wake up earlier and show more frequency of poor sleep quality than those who start classes in the afternoon. Between them, those who have a preference for intermediate or later hours for sleep are more irregular in their wake up schedules and increase their sleep duration on the weekend compared to those with earlier sleep preferences. On the other hand, working only in the afternoon seems to provide better sleep/awake conditions for teachers, because they keep the same sleep duration during the week and on the weekend, and they are diagnosed with less daytime sleepiness. Therefore, the discussion of school start times, originally proposed for adolescents, needs to be magnified to teachers, contributing to improvement of sleep habits and life quality in school environments...
A influência do horário de trabalho nos hábitos e qualidade de sono, e sonolência diurna de acordo com preferências individuais nos horários de sono foi avaliada por questionários em 131 professores do ensino básico. Professores que iniciam as aulas ± 7:00 h acordam mais cedo e apresentam frequentemente sonolência diurna excessiva comparados aos que iniciam à tarde. Dentre estes, àqueles com preferência por horários intermediários ou tardios de sono são mais irregulares nos horários de acordar e aumentam a duração do sono no fim de semana comparados aos professores com preferência por acordar mais cedo. Em contrapartida, trabalhar somente à tarde parece proporcionar melhores condições de sono/vigília, devido não acarretar privação de sono e proporcionar menor frequência de sonolência diurna. Portanto, a discussão do horário de início das escolas originalmente levantada para adolescentes, precisa ser ampliada para professores contribuindo para melhora nos hábitos de sono e qualidade de vida no ambiente escolar...
La influencia del horario de trabajo en los hábitos y la calidad del sueño (dormir) y la somnolencia diurna según cronotipo se evaluó por cuestionarios en 131 maestros. Los maestros que empiezan las clases a las ±7:00 h despiertan más temprano y tienen con frecuencia somnolencia diurna en comparación con los maestros que inician las clases por la tarde. Entre ellos, los intermedios y trasnochadores son más irregulares en los horarios de despertar en comparación con los madrugadores. Además, aumentan la duración del sueño el fin de semana. Por otra parte, trabajar solamente por la tarde parece ofrecer mejores condiciones para el sueño y vigilia del maestro, debido no causar privación del sueño y proporcionar menor frecuencia de somnolencia diurna. Por lo tanto, la discusión del horario de inicio de las escuelas originalmente planteadas para los adolescentes, debe ampliarse a los maestros contribuyendo para mejorar los hábitos del sueño y la calidad de vida en la escuela...

The aim of this study was to characterize the sleep-wake cycle, daytime sleepiness and sleep quality of high school teachers. Ninety-eight high school teachers participated in this study. They were asked to complete the Health and Sleep, Horne & Ostberg, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index questionnaires and to keep a 14-day sleep diary. This study showed that high-school teachers wake up on average 1 h 12 min earlier (ANOVA; p < 0.05) and go to bed on average 34 min earlier (ANOVA; p < 0.05) during the week than on the weekend. This results in an average of 42 min less time in bed (ANOVA; p < 0.05) on weekdays and characterizes partial sleep deprivation. Moreover, 46% and 51% of teachers were diagnosed with excessive daytime sleepiness and poor sleep quality (χ2; p > 0.05), respectively. Therefore, high-school teachers show characteristics of partial sleep deprivation that may contribute to excessive daytime sleepiness and poor sleep quality. This situation may compromise health and quality of life, in addition to teaching performance that can affect the education of their students.

A delay in bedtime occurs in adolescence compared with childhood. However, the early waking that morning school hours impose leads to partial sleep deprivation. Although exposure to light is the most important regulator of circadian rhythm in mammals, physical exercise influences circadian synchronization. To assess the effect of morning physical exercise in sunlight on the sleep-wake cycle (SWC) in adolescents, 160 first- and second-year high-school students were exposed to classes in their usual classroom (Group C) or in a swimming pool exposed to sunlight (Group E) while physically exercising (EE; i.e., swimming) or resting (EL). At baseline, we applied Health and Sleep and Horne & Ostberg chronotype assessment questionnaires. One week later and during the intervention, we applied the Sleep Diary and Karolinska Sleepiness Scale. During the intervention we observed no changes in bedtime, time in bed and in indices of irregularity of bedtime and wake-up time. The changes observed in wake-up time (i.e., a delay in the EE group on Saturday), sleep quality (i.e., an improvement), and sleepiness (i.e., an increase) were also observed in the control group, discarding an intervention effect. We suggest that morning physical exercise in sunlight had no effect on SWC parameters, sleep quality, or daytime sleepiness, possibly because of the large irregularity in the SWC between weekdays and weekends in adolescent students as well as the low frequency and duration of exercise during the intervention. Therefore, studies that evaluate a higher frequency or duration of exercise are needed to assess its effect on the SWC in adolescents.
