Caffeine can help increase reaction time and improve performance for military servicemen who must perform complex tasks or who need help staying alert for longer periods of time, according to a new report by the National Academy of Sciences. The report, by the academy's Institute of Medicine, found that 100 to 600 mg of caffeine, the equivalent of one to six cups of coffee, can help "maintain cognitive performance," especially in times of sleep deprivation.
