“…In light of that, it is also essential to develop actions and strategies that promote sleep hygiene, i.e., which creates an environment that facilitates sleep, including this aspect in the routine of services and planning of health actions. Some strategies are building a daily routine, avoiding consuming products with caffeine before bed, avoiding using technology before bed, and adjusting the room temperature to provide a more comfortable environment [44]. Another factor that has been studied and associated with sleep quality and duration is the start time of classes, with morning students having a shorter sleep duration [45,46].…”

Does asthma cause sleep disorders … or the other way around?

“…This is the direction of the study by Estanislau et al 1 and other studies, from which it is worth mentioning one published in 2015 by Li et al 8 for in one hand they assess this association by a cross-sectional study by means of questionnaires in a big population of 20,672 children (response rate 91.9% and age range 5–12 years); and on the other, they include a meta-analysis of 12 previous studies including 38,766 children. In the cross-sectional study the find that both snoring (OR = 1.28, 95%CI: 1.01–1.62) and OSA (OR = 1.92; 95%CI: 1.34–2.76) are statistically significant asthma predictors.…”

“…In the present issue of the Jornal de Pediatria, the paper by Estanislau et al 1 assesses the association between the hours of sleep and the suffering from asthma in adolescents. The study was designed considering that the independent variable in the regression analyses is sleep, while the dependent one is asthma.…”

Paediatric asthma and non‐allergic comorbidities: A review of current risk and proposed mechanisms

“…112 Furthermore, two large population studies from South Korea and Brazil observed a negative association between asthma and sleep duration. 107,113 However, this association did not extend to studies on asthma severity. 109,114 In regards to sleep hygiene and daytime sleepiness, an association between poor asthma control with later bedtime and increased daytime sleepiness has been demonstrated, 106,110 but again, there was no association observed when focusing on asthma severity or asthma controller medication use.…”
