School
A National Sleep Foundation survey found that college/university-aged students get an average of 6.7 hours of sleep each night. Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the National Chung Cheng University in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the University of Minnesota did research that compared students who went to school at 7:15 am and those who went to school at 8:40 am. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S. high school students admits to falling asleep in class at least once a week. It is known that during human adolescence, circadian rhythms and therefore sleep patterns typically undergo marked changes. Electroencephalogram (EEG) studies indicate a 50% reduction of deep (stage 4) sleep and a 75% reduction in the peak amplitude of delta waves during NREM sleep in adolescence. School schedules are often incompatible with a corresponding delay in sleep offset, leading to a less than optimal amount of sleep for the majority of adolescents.

Famous quotes containing the word school:
“There is nothing intrinsically better about a child who happily bounces off to school the first day and a child who is wary, watchful, and takes a longer time to separate from his parents and join the group. Neither one nor the other is smarter, better adjusted, or destined for a better life.”
—Ellen Galinsky (20th century)
“Mary had a little lamb,
Its fleece was white as snow,
And every where that Mary went
The lamb was sure to go;
He followed her to school one day—
That was against the rule,
It made the children laugh and play,
To see a lamb at school.”
—Sarah Josepha Buell Hale (1788–1879)
“The difference between de jure and de facto segregation is the difference open, forthright bigotry and the shamefaced kind that works through unwritten agreements between real estate dealers, school officials, and local politicians.”
—Shirley Chisholm (b. 1924)
