Nowadays many people stay up late, especially for those people who have variable sleep schedules, such as university students. University students usually change their sleep schedules due to studying, working for a living, or working for social networking (e.g., alcohol and caffeine consumption).
Staying up late usually leads to insufficient sleep, and this situation is prevalent among university students. According to a survey done by Leon C. Lack Ph.D. in the journal “Delayed Sleep and Sleep Loss in University Students”, “A sample of 211 university first-year psychology students… accounted for about 50% of the total enrollment in the course… about 50% of the sample complained of insufficient sleep and estimated needing about half an hour more sleep on the average to feel rested.” (Lakc, 2010) Moreover, the author also realized the linkage between staying up late and the insufficient sleep, “Delayed sleep pattern presumably arises from a delay in their endogenous biological rhythms that creates difficulty in falling asleep early enough to get sufficient sleep before necessary weekday morning awakening.” (Lakc, 2010) Both delayed sleep and insufficient sleep can cause serious healthy issues, and also affect one’s working productivity. Based on the Journal named “Pathways to adolescent health sleep regulation and behavior” by Ronald E Dahl, M.D., “There is mounting evidence that sleep deprivation has its greatest negative effects on the control of behavior, emotion, and attention… the most obvious direct health consequences of insufficient sleep are high-risk behaviors associated with substance abuse and automobile accidents.” (Dahl, 2002) Delayed sleep may harass one’s circadian rhythm, and further lead to delayed...
