Sleep deprivation has been found to affect mood as well. [47] This effect is most pronounced in those that are consistently partially sleep deprived, which is the case for many college students.

The first, a 2006 study in the American Journal of Epidemiology, found that, while white women and white men sleep over six hours a night on average, Black women sleep just 5.9 hours a night and ...
Given the significant impact of sleep deprivation on academic performance and the differing sleep patterns observed in students, educational institutions have begun to reconsider start times. For instance, a school in New Zealand changed its start time to 10:30 a.m. in 2006, to allow students to keep to a schedule that allowed more sleep.
One early study into neurochemical influences on sleep and memory was conducted with cats and demonstrated that sleep deprivation increased brain protein synthesis. There is evidence that these altered levels of proteins could increase the excitability of the central nervous system, thus increasing the susceptibility of the brain to other ...
The majority of college students fall in this age range. While sleep is critical, many college students do not reach this threshold amount of sleep, and subsequently face detrimental effects. However, it is clear that stress and sleep in college students are interrelated, instead of one only affecting the other. "Stress and sleep affect each other.
In the study, 70.6% of students reported obtaining less than 8 hours of sleep, and up to 27% of students may be at risk for at least one sleep disorder. [142] Sleep deprivation is common in first-year college students as they adjust to the stress and social activities of college life.

On the other hand, a few recent studies have supported a theory of creative insomnia, in which creativity is significantly correlated with sleep ...
