A cup of coffee can get you going in the morning, but it may also help you remember all the details of your morning meeting a bit better. The results from a recent research study from published online in Nature Neuroscience shows that coffee can actually improve your memory. The study involved asking a group of men and women to study pictures of a variety of objects and then given (or not given) the caffeine equivalent to 2 cups of coffee. The next day, the subjects were asked to perform a test that would show how well the remembered the images from previous day and the caffeine-assisted people consistently remembered more accurately than the group without caffeine. Memory wasn’t helped by just a half a cup, you needed at least the 2 cup dose to see results in the study.
These results back up previous findings that the caffeine in coffee makes you more alert and that alertness allows you to pay more attention to anything you need to remember, but this shows that it likely improves your ability to recall that information later. This isn’t to say that it is a memory pill that will suddenly turn you into Sheldon from Big Bang Theory (if it did, you probably would already have noticed that), just that you shouldn’t hesitate to take that second cup in the morning because it will probably pay off later in the work day.
