Sleep–wake habits and circadian preference in Mexican secondary school

Morningness–eveningness is not associated with academic performance in the afternoon school shift: Preliminary findings

“…The results of this study indicated that time in bed decreases more in the morning shift than in the afternoon shift (7:16 vs. 9:14 hr), which is similar to what Arrona‐Palacios et al . () reported in a previous study (7:11 vs. 9:23 hr). Mexican adolescents from the morning shift had less time in bed compared to adolescents from American samples (7:28 hr), Asian samples (7:38 hr), and European samples (8:26 hr) (Gradisar, Gardner, & Dohnt, ).…”

“…Therefore, almost all parents want their children to attend school in the morning shift. Double‐shift school system studies on sleep have been scarce in Mexico (Arrona‐Palacios et al ., ; Valdez, Ramírez & García, ). Therefore, the benefits of a late school start time (afternoon school shift) on sleep habits and circadian rhythms in adolescents have not been promoted in the country.…”

“…Therefore, the benefits of a late school start time (afternoon school shift) on sleep habits and circadian rhythms in adolescents have not been promoted in the country. The results of this study and previous studies (Anacleto et al ., ; Arrona‐Palacios et al ., ; Carissimi et al ., ; Natal et al ., ; Valdez et al ., 1996) may be used as examples of how a late school start time prevents adolescents from presenting sleep restriction.…”

“…According to previous double‐shift school system studies on sleep habits, morning shift students reported shorter sleep duration and daytime sleepiness and were exposed to bright light earlier than adolescents from the afternoon shift. In contrast, afternoon shift students reported longer times in bed and later rising times and bedtimes and were exposed to bright light later than morning shift students (Anacleto, Adamowicz, Simões da Costa Pinto, & Louzada, ; Arrona‐Palacios, García, & Valdez, ; Carissimi et al ., ; Natal et al ., ). Some studies have analysed the consequences of sleep habits when adolescents change from one school shift to another (e.g., from an afternoon shift to a morning shift).…”

Análise dos parâmetros rítmicos e de sono, cronotipo e jetlag social em adolescentes: relações com o gênero, turno escolar, atividades noturnas e desempenho cognitivo

“…KOPASZ et al, 2010;DE BRUIN et al, 2017). No entanto, recentemente autores mostraram que as notas nas mesmas classes e ensinadas pelos mesmos professores mostraram um aumento de 4,5% após um atraso de 55 min para o início das aulas, que foi associado com um sono diário significativamente mais longo(DUNSTER et al, 2018).ESCRIBANO et al, 2012;MARTIN et al, 2016).Em contraste, outros descobriram que os estudantes de cronotipo vespertino são tipicamente mais privados de sono no turno escolar da manhã,(KOŠĆEC et al, 2014;ARRONA-PALACIOS et al, 2015), mostram maior jetlag social,VOLLMER et al, 2017) menor atenção, desempenho escolar e cognitivo(GOLDSTEIN, et al, 2007;VOLLMER et al, 2013;VAN DER VINNE et al, 2015) Span de Dígitos (versão inversa) do que os testados no turno da manhã. Com a análise da sonolência também mostramos que os estudantes do turno da manhã testados pela manhã eram mais sonolentos do que os do turno da manhã testados à tarde.…”
