Staying up late surfing the internet or playing on the X-Box is not going to improve your child’s performance at school. You know it, and although your kids might dispute it, a recent study of teenagers in Sweden shows it to be true.
Around 40,000 children were asked questions about how many subjects they had failed during the school year, whether their sleep was disturbed, and how long they spent asleep each night.
Analysis of the results shows adolescents who reported sleep disturbances were more likely to fail at least one subject during the school year. Also, children who reported that they didn’t sleep for many hours each night – either during the week or at the weekend – were more likely to fail at least one subject at school, when compared with children who slept at least seven to eight hours every night.
