Sleep Quantity and Quality in Relation to Daytime Functioning in Children

This study examined sleep in relation to daytime functioning in 32 typically developing children (8–12 y). Participants wore actigraphs for one week and then completed tasks designed to measure emotional functioning, short-term memory, working memory, and attention. Results revealed that children slept approximately 1 h less per night than recommended. Older children had shorter sleep durations, higher sleep efficiencies, and later sleep onset times. Examination of the relationships between sleep and daytime functioning revealed that small variations in sleep were significantly associated with differences in emotional functioning and attention. Results highlight the need to increase awareness about the importance of sleep in children.
