Until recently, there was little evidence supporting that coffee is beneficial when studying, studying, and exam preparation. But the results of a recent study, conducted by a group of American researchers, proved that coffee stimulates and strengthens memory.
It is known that coffee, with its caffeine content, helps you stay awake because of its stimulating effect on the body, but until now there have been few clues indicating the positive effect of coffee on memory. This has changed today, according to a study conducted by a group of researchers at the Johns Hopkins Center at the University of Baltimore, USA, and their results were published in the scientific journal Nature Neuroscience.
US researchers conducted an experiment in which they asked 73 volunteers to look at a set of photos. Then half of the participants in the experiment consumed 200 milligrams of caffeine, equivalent to two cups of espresso, and the other half did not drink caffeine. This came in an article published on the website of the German newspaper Frankfurter Allgemeine Zeitung.
Then, three samples of the participants’ saliva were taken, the first after one hour, the second after three hours, and the last after 24 hours, to measure the level of caffeine. The next day, members of the two groups were asked to look at a new set of photos and to determine which ones were among the first-day pictures and which were not among them.
The result was: Those who consumed caffeine were able to better than others remember any pictures they had seen the previous day and identify differences between similar ones. In Frankfurter Allgemeine Zeitung’s article, quoting Michael Yasa, one of the American researchers participating in the experiment, it is much more difficult to identify the differences between similar images than between known and unknown images for the brain. This was demonstrated by the experience that caffeine stimulates the brain and strengthens memory.
