Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
Sleep is also important for brain health, as poor sleep is a risk factor for cognitive issues such as memory loss. “Depriving humans of sleep leads to all sorts of problems and can cause serious ...
The effects of sleep deprivation on cognitive performance are a broad range of impairments resulting from inadequate sleep, impacting attention, executive function and memory. An estimated 20% of adults or more have some form of sleep deprivation . [ 1 ]
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.

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 ...
During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems; [3] these are vital processes that maintain mood, memory, and cognitive function, and play a large role in the function of the endocrine and immune systems. [4]
Irregular sleep schedules can cause negative impacts on learning, memory, and performance. The dual process theory determines that certain types of memory depend on specific sleep states, like REM and NREM (Non-Rem) states. REM sleep deprivation can reduce sleep-induced improvement such as visual perception, thus influencing how one learns.
