Sleep Researchers Study Value of Preschool Naps

Parents may feel it's clear that missing a nap means their young children will be grumpy and out-of-sorts, but scientists who study sleep say almost nothing is known about how daytime sleep affects children's coping skills and learning.

Now neuroscientist Rebecca Spencer at the University of Massachusetts Amherst has received a five-year, $2 million grant from NIH's Heart, Lung and Blood Institute to significantly advance knowledge about how napping and sleep affect memory, behavior and emotions in preschoolers.

"Right now, there's nothing to support teachers who feel that naps can really help young children, there's no concrete science behind that," the neuroscientist says. "But if sleep is going to enhance all these benefits of attending preschool, we need to know it."

Over the next five years, Spencer and her graduate students hope to study about 480 preschoolers between 3 and 5 years old, boys and girls in diverse communities across western Massachusetts. The research will include fact-based and emotional memory studies with and without napping, measures of physical activity levels and parent reports of their children's' nighttime sleep, to find out how classroom experience interacts with sleep and physical activity and whether daytime sleep enhances learning. The research will also explore the relationship between sleep and behavior disorders.

"I think we'll have a rich data set for examining sleep, physical activity and the child's behavior," says Spencer. "We think that the nap benefit is going to be especially useful for kids who don't get optimal overnight sleep. Culture plays a role in how late you stay up, and some kids live in noisy inner city neighborhoods. If we can help them with a nap, we want to know that."
