7 Unbelievable Facts About What Caffeine Does to Your Body

Memory Boost

John Hopkins University of Baltimore, Maryland, conducted a study in which people who did not consume caffeine were either given a placebo or a caffeine supplement and were asked to view images 1, 3 and 24 hours apart. These pictures were changed slightly after 24 hours, and the individuals who consumed the caffeine supplement were more likely to notice the changes rather than claiming it was the same image. Caffeine is also used by many students across the world as a study-aid to have enough energy to cram the night before an exam. Caffeine has had mostly positive effects in studies of long-term memory and habitual consumption, but studies of caffeine and short-term memory are thought to be highly inconsistent.
