School-age children who get less than the proper amount of sleep are less likely to perform well in school, according to new research.
The scientific study, conducted on 142 children in Spain, tracked how well the primary school children performed on tests of academic skills and how much sleep they received.
Most of the six and seven-year-olds were less able to communicate and work out basic maths questions when deprived of sleep, researchers found. Their spelling, grammar and comprehension also suffered, but their memory and ability to learn were less affected.
The lead researcher at the Autonomous University of Barcelona, Spain, said most children sleep less than recommended. Pupils who sleep eight or nine hours have a worse performance than those who sleep nine or 11 hours, he said.
