Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Experimental group (with daytime classroom nap) versus control group (without nap)
Primary purpose: TREATMENT

Brief summary: Previous studies showed that insufficient sleep has a negative impact on children's physical and psychological health. Napping was found to decrease sleepiness and improve daytime functioning in adults and adolescents. The effects of napping on children, however, is unknown. The current study aims to test the effects of short daytime classroom naps on daytime functioning and behaviour in elementary school children.

Detailed description: This study is an interventional study testing the effects of short daytime nap on children's cognitive functioning and daytime behaviour. Primary school children will be randomised to either experimental (nap) or control group (no nap) by class. Measurements include parent-report questionnaires, children's self-report questionnaires, and cognitive tasks.

Eligibility criteria: Inclusion Criteria:

* Children from grade 1, 2, 3, 5, and 6
