Long-term chronic exposure to insufficient sleep is associated with a decline in optimism and sociability, and an increase in subjective experiences of sleepiness and fatigue. [16] Furthermore, sleep restricted to five hours a night over the course of a week causes significant increases in self-reports of subjective mood disturbance and sleepiness.
The cognitive consequences of sleep deprivation, such as memory impairment and poor attention capacity, are well documented, but when you ask someone who's sleep deprived what their memory is like ...
Compounding this is the proven dissociation between objective performance and subjective alertness; people vastly underestimate the effect that sleep deprivation has on their cognitive performance, particularly during the circadian night. [56] Many of acute sleep deprivation's effects can be countered by napping, the longer the more beneficial ...
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. Poor sleep can increase stress, otherwise high-stress can also cause sleep disturbances". [8] As stated in a different way, the way stress and sleep are related is bidirectional in nature ...
Chronotype can affect how sleep deprivation influences mood. Those with morningness (advanced sleep period or "lark") preference become more depressed after sleep deprivation, while those with eveningness (delayed sleep period or "owl") preference show an improvement in mood. [62] Mood and mental states can affect sleep as well.
Mood. 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.
Other studies have been also looking at the specific effects of different stages of sleep on different types of memory. For example, it has been found that sleep deprivation does not significantly affect recognition of faces, but can produce a significant impairment of temporal memory (discriminating which face belonged to which set shown).
Multiple hypotheses explain the possible connections between sleep and learning in humans. Research indicates that sleep does more than allow the brain to rest; it may also aid the consolidation of long-term memories. REM sleep and slow-wave sleep play different roles in memory consolidation. REM is associated with the consolidation of ...
