CONTEXT / BACKGROUND PROJECTStudents with a deficit of sleep or irregular sleep schedules are worse in school than their peers; sleep deficit with a delay of more than 2 hours sleep onset on weekends is associated with poor school performance.Infant sleep patterns are influenced by several factors: starting school schedules, family schedules, socio-demographic, daytime activities, homework and extracurricular activities. The dream education programs should include students, families and educators.These interventions should be carried out throughout the school year taking into account the start and end times of the schedule; delay time can sometimes be an option.OBJECTIVESDemonstrate that the implementation of healthy sleep habits within the school curriculum has beneficial short and long term effects.Check schedules that adapt the curriculum to chronobiology and cronopsicología favors school performance by streamlining teaching activities.Organizations participating in the project: to Spain:City Council Silla (coordinator),Health Hospital Quirón Valencia,Preschool centers, elementary and secondary schools: IES Enric Valor, IES Sanchis Guarner, CEIP El Pati, CEIP Reis Catòlics , CEIP San Roque, CEIP V. dels Desemparats.Parent's and students associations: AMPA IES Enric Valor, Sanchis Guarner IES AMPA, AMPA CEIP El Pati, AMPA CEIP Reyes Catolics, AMPA CEIP San Roque, AMPA CEIP V. Desemparats, AMPA CC Sagrada Família, Studen's Association IES Enric Valor. b) Turkey:Ünye: City district of Ordu province in the region of the Black Sea. c) Italy:Remedello: Lombardy City of 2,996 habitants.Belvi: Cerdenya City of 800 habitantsPREPARATION Formation of educational establishment: Two theoretical 4-hour sessions in which each is explained by the scientist responsible for the project.Two practice sessions 4 hours to prepare concrete measures to establish in the classroom.IMPLEMENTATION PHASE1. Application of different strategies designed.2. Making specific tutorials.3. Assessment of sleep habits of students with subjective measures by three different surveys.CONCLUSIONS - Global improvement in sleep quality of students. This improvement shows differences between the three countries studied.- Students have increased their degree of self-responsibility in deciding their own sleep schedules. This empowerment has led to a decrease in daytime sleepiness accompanied by an improvement in school grades.- The involvement of teachers in the project themselves being the designers of the measures to be taken and those responsible for its implementation in the classroom and contact with families, is key in the program.- The need for a more direct and strict health professionals with education professionals and the importance of institutional support contact is observed.The research group believes that these measures knowledge and care of the rest of the students with respect chronobiological rhythms are cost-effective and should be recommended for implementation in schools of the European Union.RELEVANT LONGER TERM BENEFITSThe second survey has confirmed the persistent academic and behavioral benefits in the first year. So the continuous introduction of measures of sleep hygiene in schools involves the persistence of benefits in school performance.
