Nap routine in Japanese nursery schools:Developmental change of diurnal naps in children and their effects 福田, 一彦 フクダ, カズヒコ Developmental process Diurnal naps Preschoolers Cessation of routine naps P(論文) During the preschool period, the number of children who take afternoon naps decreases, and finally almost no children take naps at the time of entrance to elementary schools. Study 1: We conducted actography monitoring of nursery school children. In many Japanese nursery schools, children were forced to take long afternoon naps regardless of their age. The children with lengthy afternoon naps showed clear delayed nocturnal sleep onset. Study 2: In nursery schools run by Adachi city in Tokyo, obligatory naps were discontinued after 2011. We compared children’s nighttime sleep before and after the cessation of routine naps. The children’s bedtime was significantly advanced after the nap cessation. The children fell asleep more easily after the nap cessation. Study 3: National Sleep Foundation（ 2004） surveyed American children‘s sleep and found 43% of age 3, 74% of age 4, 85% of age 5, and 98% of age 6 take no naps. We conducted a survey on the sleep of 2,573 children of age 3 to 6 living in Tokyo, and found more children take no naps during the preschool period （i.e., about 70% of age 3, 80% of age 4, 90% of age 5, and 95% of age 6）, when asked if the children take naps by their own natural need, not by preschool’s daily routine. The difference between the two surveys was thought to be attributed to the difference in the question asked. The American survey asked the parent whether their children take naps or not. They are not necessarily the percentage of the nap from the children’s own needs. Conclusions: Lengthy naps should not be taken by children who could maintain their wakefulness during the daytime. 江戸川大学 2023-03-15 eng departmental bulletin paper https://doi.org/10.50831/00001184 https://edo.repo.nii.ac.jp/records/1212 10.50831/00001184 AA12560733 江戸川大学紀要 Bulletin of Edogawa University 33 63 69 https://edo.repo.nii.ac.jp/record/1212/files/DK2023-05.pdf application/pdf 2.1 MB 2023-04-19
