In an earlier study by Lieberman (1988) it was also proven the caffeine was to reduce depression when in was ingested in moderate doses (Smith, 2002). Many studies have focused with a large consumption of caffeine or with a single dose of caffeine never truly addressing the tolerance of the participants or seeing the long lasting effects of caffeine on the participants (Soar, Chapman, Lavan, Jansari & Turner, 2016).
