An Hour More Sleep May Help Kids Learn

Much the same is true of adults, says Isaacson. "When you sleep late on the weekends, you find yourself repeatedly waking up a little in the morning -- which I find quite delicious, myself. When I get up, I feel fresher and better able to perform."

Almost all studies have shown that when people are deprived of sleep, their mood and ability to perform tests is a bit worse, Isaacson says.

"Having a ritualistic bedtime pattern, especially for younger kids, will help them slow down, get ready to sleep. Also, avoid caffeine and sugar before bedtime because it gives the body the wrong signals and won't let them feel sleepy," he advises.

With teenage kids, a later bedtime may be more acceptable -- since studies have shown that a teen's natural pattern of sleep is to go to bed later and wake up later, says Isaacson.
