The Effects of Caffeine on Sleep Patterns Among Adolescents

  • Lauren E Margolis Vanderbilt University


This review of literature examines whether there is a causal relationship between caffeine consumption and sleep patterns among adolescents. Literature suggests that there is a cause and effect relationship between caffeine intake and cognitive performance in adults. Researchers also found that among the adult population, consuming caffeine before sleep resulted in increased sleep onset time, reduced total sleep time, and poorer sleep quality. Specifically, adolescents ingest the majority of their total caffeine intake through caffeinated sodas. Studies have shown that adolescents consume more caffeine later in the week, which correlates with shorter total sleep time and decreased sleep quality. Thus, in review of the literature, it was determined that caffeine negatively affects sleep habits among adults, but further research should be conducted in order to conclude whether this relationship holds true among adolescents.
