The first state in a sleep cycle is light sleep, followed by deep sleep and a dream state called REM sleep. A complete sleep cycle lasts approximately 90 minutes and is normally repeated several times each night. The college experience is of great value in providing emerging adults with a structured environment in which they can gain knowledge, skills and independence to chart their own path, become a successful worker, a good citizen and contribute to society. One potential barrier to maximizing college success is the high prevalence of daytime sleepiness, sleep deprivation, irregular sleep schedules, and lack of nighttime sleep among college students. Daytime sleepiness is a serious problem, highlighted by 60% of college students compared to 34% of adolescents and adults.

Sleepiness is defined as the inability or difficulty in maintaining attention during the main waking period of the day, resulting in involuntary lapses into drowsiness or sleep. It is important to note that sleepiness is often circumstance-dependent, as many aspects of students' learning environments exacerbate sleepiness. For example, a lesson that does not require active participation and can take place in a dark, warm classroom can unmask hidden drowsiness. Drowsiness and irregular sleep schedules have many unwanted consequences, which negatively impact learning, memory and performance.

Dual process theory holds that certain types of memory depend on specific sleep states, such that procedural memory (knowing how) might depend on rapid eye movement (REM) sleep, and declarative memory (knowing what) on sleep. NREM. Sequential processing theory suggests that memory requires an orderly succession of sleep stages, that is, memory formation can be stimulated by slow-wave sleep and consolidated by REM sleep.

To understand the consequences of sleepiness and sleep patterns, knowledge of normal sleep and its impact on learning, memory, and performance is needed. Many college students are sleep deprived because they go to sleep late and wake up for class before they get adequate sleep. This will happen for multiple reasons; some are physiological and some behavioral. There is little doubt among healthcare professionals about the critical importance of sufficient, restful sleep in maintaining one's physical and mental health.
