Investing in sleep is good strategy
Cram sessions can cause illness
By Katherine Manweiler
Kansan staff writer
Some students may think six to eight hours of sleep a night is an unaffordable luxury during midterms, but health officials say late-night cram sessions can do more harm than good in the long run.
Myra Strother, physician at Watkins Memorial Health Center, said sleep deprivation was a common problem for college students, especially during exam periods.
She estimated that 40 percent of the students treated at Watkins during finals last semester were sick as a direct result of not getting enough sleep.
When people's immune systems are depleted, they are more susceptible to colds, viruses and other illnesses, she said.
"We usually see them not just because they're exhausted," Strother said. "But often their immune system gets run down."
"It's too bad, because they're stay up to study, but it doesn't do them any good," she said. "It would probably be better for them to take the hours that they were planning to use to cram and sleep instead."
Sleep deprivation also lowers intellectual capacity. Studies indicate that students who do not get adequate sleep have decreased performance on tests, Strother said.
Stress levels are increased dramati-
Strother said a combination of sleep deprivation and artificial stimulants, such as caffine, could decrease students' concentration levels to the point at which students were unable to study.
She said that if students were sleepeprived and under the influence of too much caffeine, they needed to let the effects of the caffeine wear off and then go to bed.
Long-term effects on the body from sleep deprivation include memory loss, difficulty concentrating and nutritional deficits caused by a loss of appetite, Strother said.
Bob Whitman, director of the sleep disorders laboratory at the University of Kansas Medical Center, said occasional loss of sleep would not harm students.
"The general consensus is that students who have a normal sleeping pattern can tolerate extended periods with prolonged reductions in sleep of an hour or an hour and a half without consequences in performance," he said.
Alcohol increases the negative effects of sleep deprivation, Whitman said.
Bob Whitman is director of the med center's sleep disorders laboratory.
"People don't recognize the fact that their performance is decreased because they feel alert," he said. "People who deprive themselves of sleep and drink alcohol may feel that they have no problems with tasks, but the results show differently."
Whitman said it was smarter for students who felt pressed for time to limit consistently their amount of sleep to six hours a night than to pull all-night
studv sessions.
"We see three times as many stress-related problems during finals," she said.
cally when people do not get enough sleep, Strother said. Increased stress can cause ulcers, heartburn and panic attacks
Cramming for sleep often has the same results of cramming for exams, he said.
"If students consistently decrease the amount of sleep they get and then try to use a couple of days over the weekend to catch up, it won't help a wholelot," Whitman said. "Come Monday morning, they are still going to feel tired."
