American society is not
nap(午睡)friendly. In fact, says David Dinges, a sleep specialist at the

to fall asleep at work is to take naps when you need them. "we have to totally
change our attitude toward napping", says Dr. William Dement of Stanford

They had 824 undergraduate(大学本科生的)students complete a health survey that included questions about sleep habits and daytime functioning,and found that students who are morning people had higher grade point averages (GPAs)than those who are night people.
“The finding that college students who are evening types have lower GPAs is a very important finding,sure to make its way into undergraduate psychology texts in the near future,along with the research showing that memory is improved by sleep,” study co-author Daniel J. Taylor said in a prepared statement.
“Further,these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法)to help students retrain their biological clock to become more morning types,“ Taylor said.
