A new study confirms that better sleep equals better learning. When a school age child receives a good nights sleep, better performance in math and languages becomes more likely.
Sleep quality and duration are linked to better math and language performance according to a study performed by researchers from McGill University and the Douglas Mental Health University in Montreal.
Researchers found that “sleep efficiency” was linked to higher academic performance in key subjects. Sleep efficiency was defined as sleep quality that relates to the amount of actual sleep time and the total time spent in bed.
The study was published in the journal Sleep Medicine. Other studies have linked sleep and general performance, this one was unique in that it examined the effect of sleep quality on specific report card grades. Grades in other subjects, such as science and art, were not affected.
“We believe that executive functions (the mental skills involved in planning, paying attention, and multitasking, for example) underlie the impact of sleep on academic performance, and these skills are more critical in math and languages than in other subjects,” says Reut Gruber, a clinical child psychologist who led the study.
