Every now and then, science reveals something amazing. In 2014, Johns Hopkins University conducted a study that provided evidence that drinking coffee helps memory processing.
Unlike the majority of other studies in this area, this particular study looked at the brain’s pattern separation ability, which is also known as the ability to recognize a difference between two items that is similar, yet not 100% identical.
Participants were divided into two groups. One group received a 200mg caffeine tablet, and the other group received a placebo. The tablets were administered exactly five minutes after the participants were asked to observe a range of images. Salivary samples were taken before the tablets were administered, as well as after one, three and 24 hours.
Individuals who were given a 200mg caffeine tablet had improved long-term memory recalling abilities after a 24-hour period, and their pattern separation abilities worked better than the group who were given a placebo.
