When the mind's need for rest is not satisfied, it accumulates a "sleep debt" that cannot be repaid by a single bout of sleep. “The brain keeps an accurate count of sleep debt for at least two weeks” (Myers, DeWall 107). Many college students experience sleep deprivation which results in fatigue throughout the day. Whether or not it's due to roommates or your habits, sleep deprivation is a problem. Although sleep is often overlooked and not considered a significant event, as it should normally occur every day, it is a necessity for all humans and animals. “It is said that young animals can go longer without food than without sleep” (Johnson 88). This statement shows how important the role of sleep is in life. “Approximately 70% of college students report sleep disturbances including poor sleep quality, insufficient sleep, and irregular sleep patterns” (DeMartini, Fucito 1164). Most of the time college students have trouble sleeping due to their changing schedules. On weekdays, students will sleep between classes and stay up late trying to get work done. On weekends they stay up late and wake up later in the day. “According to the National Sleep Foundation, 59% of adults ages 18 to 29 describe themselves as night owls” (Gaultney 91). Our bodies are synchronized with the 24-hour cycle thanks to the circadian rhythm (Myers, DeWall 100). If students can't fall asleep early because their "biological clock" is messed up due to stress or other reasons, they won't get enough sleep in the morning. Research has shown that people who rise earlier generally perform better in school, have more initiative, and are less likely to be depressed (Myers, DeWall 101). Other sleep deprivation factors might fall into the social category. College students tend to enjoy life and party. This is something a college student can do
