  1. Caffeine is a crystalline compound that is found especially in tea and coffee plants and is a stimulant of the central nervous system. It is ranked as one of the most well-known and highly consumed drugs (James, 1997). Caffeine is absorbed quickly in the body when consumed as it is highly soluble (Weinberg &amp Bealer, 2001). Once absorbed, caffeine is equally transported to all body tissues. It is also secreted equally in saliva, breast milk, and semen (Chambers, 2009). Various factors affect caffeine concentration of caffeine in the body and the half- life of caffeine can go up to nine hours (James, 1997 Weinberg &amp Bealer, 2001).

  2. The purpose of this quantitative study is to investigate the relationship between caffeine consumption and sleep patterns among undergraduate students.


  1. Importance of Sleep

Sleepforms the major part of human life and all organisms require sleepfor their survival (Reinoso-Suarez, de Andrés, &amp Garzón, 2011).However, it still remains a mystery for all those who have tried tounderstand how sleep works. On average, adults require about sevenif not eight hours of sleep every day (Chaput et al, 2008). It ishighly recommended that college students should spend six to ninehours sleeping on a daily basis for their bodies and mind to functionwell (Chaput et al, 2008).This is simply because fewer hours of sleepmay result in negative effects such as weight gain and also mayresult in high mortality rates (Hublin, Partinen, Koskenuvo, &ampKaprio, 2007).

  1. Consequences of Caffeine on Sleep Patterns

Caffeinereduces sleep (Barkoukis, Matheson, Ferber, &amp Doghramji, 2012).The effects of caffeine vary among individuals depending on the timeit is consumed and how an individual is used to it (Verster,Pandi-Perumal, &amp Streiner, 2008). The duration of caffeinetogether with its ani-fatigue features coupled with its half- life ofup to nine hours always make sleep impossible among students(Chambers, 2009). This has been witnessed in students who heavily usecaffeine experiencing little sleep pattern (Institute of Medicine(U.S.) Committee on Military Nutrition Research, 2001 James, 1997).Students who consume caffeine at a higher rate usually get less sleepthan it is recommended and therefore they can experience furtherhealth consequences (Alpert, 2012). Lack of sleep due to caffeineresults to sleep debt the amount of which should be replenished so asthe student can avoid health issues that come with caffeineconsumption (Lockley &amp Foster, 2012).



Thisoutline has shown that individuals who consume caffeine at a highrate always experience less sleep when compared to those who does notuse it. Students are said to be high caffeine consumers as they candrink up to seven cups of coffee on daily basis (Johnson-Greene,Fatis, &amp Shawchuck, 1988). Student, based on this study canconsume 1000 mg of caffeine on average. The public, in general,should be emancipated based on caffeine and its consequences on sleepso they can get the proper amount of sleep (Norton, Lazev, &ampSullivan, 2011). College students should also be educated on bothsleep hygiene and the disadvantages of caffeine consumption so as toimprove their well-being and avoid future complications that comewith caffeine consumption (Stickgold &amp Walker, 2009).
