Getting Enough Sleep

How much sleep is needed, as kids get older and move through school? And what are the benefits of getting enough sleep? Find out.

Dr. Greene’s take on getting enough sleep…

One Key to Happiness, Self-Esteem, and Success

The less sleep children get, the more likely they are to perform poorly in school, to become depressed, and to have a poor sense of self-worth, according to a study of 2,259 Illinois middle school students published in the January-February 2004 issue of Child Development.

As these kids progressed through the middle school years, if the amount of sleep dropped (as it often does), there also tended to be a further drop in grades, and self-esteem and an increase in depression. As a general rule of thumb, most middle schoolers thrive best on an average of about 9 hours. Those in high school may find that 8 hours is enough sleep; those in elementary school often do better with at least 10.

Younger children need even more. Sometimes lack of sleep is seen as a badge of honor. But at any age, getting optimum sleep improves health. It also helps people feel better about themselves and about the world. And it is a simple way to improve performance at almost anything people care about.
