Over 80% of American adults are consuming caffeine. This review examines the effect of caffeine on cognitive function and physical function, as most real-world activities require complex decision making, motion processing, and exercise. Caffeine exerts its effect by blocking adenosine receptors. Improvement of caffeine dose, arousal level, arousal level, attention, response time and attention, moderate (300 mg or 4 mg kg -1) to low (40 mg or 0.5 mg kg -1) to judgment or intention Conflicting higher order execution functions such as determination. At doses exceeding about 200 mg (~ 3), the effects on physical performance such as time to depletion, time trial, muscle strength and endurance, and high intensity sprints typical of team sports, It may affect your ability. Mg kg -1). Many occupations, including military, emergency personnel, transport workers, and factory shift workers, require optimal physical and cognitive functions to ensure success, workplace safety and productivity. In these cases, it may involve limiting sleep, and repeated administration of caffeine is an effective strategy to maintain physical and cognitive abilities.
Based on a number of literature on this topic, the impact of caffeine on cognition was examined. Caffeine sometimes promotes or inhibits memory and learning, but caffeine usually does not affect the performance of learning and memory tasks. Caffeine helps learn with the task of passively presenting information, and caffeine has no effect in the task of consciously learning teaching materials. Caffeine contributes to the performance of tasks that require a limited degree of working memory, but it hampers the performance of tasks that heavily depend on working memory and caffeine does not perform memory performance under suboptimal alarm conditions It seems to improve. However, most studies found that the reaction time was improved. Intake of caffeine does not seem to affect long-term memory. Significant improvement in the performance of fatigue subjects confirms that caffeine is a mild stimulant

The effect of caffeine on attention and psychological performance has been widely reviewed (see review). Most of the studies have shown that reaction times have improved, but not all studies have found the effect of caffeine on the two variables. Likewise, if multiple tests are used, not all tests are affected by caffeine, but it is clear that caffeine can help keep focus on important tasks is. However, in most cases, the test will be done after the drinking period (usually overnight), so there is controversy. It is unknown how much the effect of caffeine represents an absolute improvement in performance or a recovery in performance after withdrawal. In a recent study, we compared caffeine between consumers who stopped smoking overnight and non-consumers. Caffeine usually improves the mood and cognitive abilities of both groups
