Sorry kids, back to school means back to bedtime. One of the odd characteristics of our time is our apparent need for scientific verification of what we should know by simple common sense. Well, help now comes in the form of a research project undertaken by University College London. The bottom line — children with a fixed and consistent bedtime performed better on tests of cognitive ability.
As Sumathi Reddy of The Wall Street Journal reported, “Researchers at University College London found that when 3-year-olds have a regular bedtime they perform better on cognitive tests administered at age 7 than children whose bedtimes weren’t consistent. The findings represent a new twist on an expanding body of research showing that inadequate sleep in children and adolescents hurts academic performance and overall health.”
The researchers in Britain were not concerned with the amount of sleep or the time of going to bed. Their concern was the function of a consistent bedtime for children and adolescents. As they reported, having a fixed bedtime turns out to have significant cognitive advantages.
The Wall Street Journal also reported on research about the amount of sleep needed by children at different ages. As Reddy explained: ”In general school-age kids—kindergarten through eighth-grade—should be getting about 10 hours of sleep, while 3- and 4-year-olds might need 11 to 13 hours, including day-time naps, said Shalini Paruthi, director of the pediatric sleep and research center at SSM Cardinal Glennon Children’s Medical Center at Saint Louis University.”
