“In real life, the daily struggles between parents and children are around these narrow problems of an extra hour, extra TV show, and so on,”said Avi Sadeh, psychology professor at Tel Aviv University.“Too little sleep and more accidents,”he said.
Sadeh and his colleagues found an extra hour of sleep could make a big difference.The children who slept longer, although they woke up more frequently during the night, scored higher on tests, Sedeh reported in the March/April issue of journal Child Development.
“When the children slept longer, their sleep quality was somewhat weak, but in spite of this their performance for study improved because the extra sleep was more significant than the reduction in sleep quality,”Sadeh said.“Some studies suggested that lack of sleep as a child affected development into adulthood and it's more likely to develop his attention disorder when he grew older.”
In earlier studies, Sadeh's team found that the fourth graders slept an average of 8.2 hours and the sixth graders slept an average of 7.7 hours.
“Previous research has shown children in elementary school need at least nine hours of sleep a night on a regular basis,”said Carl Hunt, director of the National Center on Sleep Disorder Research in Bethesde.“And high-school-age children need somewhat less,”he said, adding the results of insufficient sleep could be serious.
“A tired child is an accident waiting to happen,”Hunt said.“And as kids get older, toys get bigger and the risks get higher.”Hunt also said too little sleep could result in learning and memory problems and long-term effects on school performance.
“This is important extension of what we already know,”Hunt said of Sadeh's research,“adding sleep is as important as nutrition and exercise to good health.”
“To put it into reality,”Hunt said,“parents should make sure they know when their children actually are going to sleep and their rooms are conducive to sleeping instead of playing.”
