Caffeine and studying
During certain times of year, such mid-term and final exams periods, students often will find themselves spending extra hours especially late at night “cramming” for those challenges. One substance students use is caffeine. Caffeine is a stimulant that is somewhat effective in keeping individuals awake and to some extent more alert.
Caffeine and alcohol
According to data and expert opinion, caffeine can mask sensory cues that people may rely on to determine how intoxicated they are. This means that individuals drinking these alcoholic beverages containing caffeine may consume more alcohol—and become more intoxicated—than they realize. At the same time, caffeine does not change blood alcohol content levels, and thus does not reduce the risk of harms associated with drinking alcohol.
