Emotional and Cognitive Impact of Sleep Restriction in Children.

Several observational, cross-sectional, and longitudinal studies as well as a few well-controlled experimental studies have examined the impact of sleep loss on children's daytime functioning. The emerging results indicate that sleep plays a critical role in various aspects of daytime functioning in children, including cognitive and emotional functioning. Furthermore, studies indicate that daytime functioning may be impaired by even small amounts of sleep restriction in children.
