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. A meta-analysis of several studies regarding sleep deprivation suggests that the effects of partial sleep deprivation are underestimated.
One such study in mice showed that sleep deprivation increases gene expression of Dnmt3a1 and Dnmt3a2, which are genes that code for enzymes that establish and maintain CpG methylation. Another study found that one night of sleep deprivation causes the hypermethylation of circadian clock genes–CLOCK and CRY1. [4]
When tested on flexibility and originality on figural and verbal tests, the sleep-deprived participants had severe and persistent impairments in their performance. [4] A study tested 30 undergraduate students from seven different academic institutions, half majoring in art and half majoring in social sciences.
Sleep deprivation also has a documented effect on the ability to acquire new memories for subsequent consolidation. A study done on mice that were sleep deprived before learning a new skill but allowed to rest afterward displayed a similar number of errors on later trials as the mice that were sleep deprived only after the initial learning.

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.
Their research on 1,043 students aged 18 to 30 revealed nearly 4 in 10 qualified as being "addicted" to smartphones, a concerning trend given sleep's vital role in cognitive function and mental ...
Creatine can boost your lean muscle mass, increase your energy before a workout, and even help you sleep better. Now, a new study suggests that the supplement could even help ease the symptoms of ...
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.
