School environment and birth order were also evaluated. As a direct consequence of such sleep restriction, a multitude of adverse outcomes affects the quality of life of this population, especially compromising health and daytime functioning. However, delayed biological bedtime and early awakening due to school attendance inevitably result in a condition of chronic sleep debt in this population.

Baker F.C., Willoughby A.R., Massimiliano d.Z., Franzen P.L., Prouty D., Javitz H., Hasler B., Clark D.B., Colrain I.M. These anatomical modifications could also be associated with the rise of peak spectral frequency of sleep spindles during adolescence [30], as a marker of cortical myelination [31]. To determine whether biological processes may underlie a delay of phase preference in adolescents, 183 sixth-grade boys and 275 sixth-grade girls completed questionnaires for morningness/eveningness (M/E) and pubertal status. We grouped the identified citations in the following categories: We focused on the effects of adolescent sleep deprivation and the impact of delaying school start time, excluding non-English articles and including the peer-reviewed published papers.

To date, the body of work on later school times is extensive and constantly growing, confirming the early work by Carskadon et al. Dinges D.F., Powell J.W.

Attention and vigilance are closely related to learning ability and cognitive function and, therefore, to success in school. D) school should begin earlier in the . [Google Scholar] 13. Future studies should also investigate the effects on the well-known phenomenon of sleep inertia, occurring during the transition from sleep to wake [134,135]. sleep, learning, school start time, academic performance, school health, sleep loss, adolescence.

The cost assumption is strictly dependent on the specific characteristics of the district (e.g., rural or urban), and it is mainly related to both potential overlap with elementary or middle school bus systems and eventual increase of traffic. The increase in longitudinally measured sleepiness across adolescence is related to the maturational decline in low-frequency EEG power. C. school should begin later in the morning . In this respect, it is worth pointing out that the study by Chan and colleagues [113] found positive effects following the shortest delay intervention applied (15 min), which could be considered a plausible compromise.

More specifically, we focus on the following issues: rele- as a result) involves several cognitive correlates that may harm the vant features of the sleep- wake cycle; how the circadian typology academic performance of adolescent students. Quiz 1: Biological Transitions | Quiz+ Additional research is certainly needed. The joint contribution of sleep, intelligence and motivation to school performance. We considered the available studies up to December 2019. A large part of this population does not experience adequate sleep, leading to chronic sleep restriction and/or disrupted sleepwake cycles.
