What can be inferred about a student who stays up all night before an exam?

Many students believe that cutting down on sleep gives them extra time to study. Research suggests the opposite. During sleep the brain sorts the information collected during the day and stores the important parts in long-term memory. A student who stays up all night before an exam may remember less than one who goes to bed at a normal hour. Sleep also affects mood: tired people become irritable more quickly and find it harder to concentrate. Doctors recommend that teenagers get between eight and ten hours of sleep each night, although surveys show that few of them reach this number on school days.
