A lot of studies over the years have shown that caffeine has many health benefits. But the newest one shows that it can boost long-term memory.

In fact, some new study published in the journal “Nature Neuroscience” suggests that if you consume caffeine after a learning session, that may help you to boost long-term memory.

To find out if caffeine has an impact on the long-temp memory, researchers analyzed 160 participants between the ages of 18 and 30. On the first day of the study, the participants were shown pictures of different objects and were asked to identify them as “indoor” or “outdoor” items. After this task, some of the participants were given 200 mg of caffeine in the form of a pill, and some received a placebo tablet. The following day, the participants were shown the same pictures from the day before, as well as some new ones. The investigators asked them to look at the pictures and to identify whether the pictures were “new,” “old” or “similar to the original pictures”. From this last task, the researchers concluded that the participants who took the caffeine were better at identifying pictures that were similar, compared with participants who took the placebo. However, the investigators noted that both groups were able to accurately distinguish whether the pictures were old or new.

The research team conducted another experiments using 100 mg and 300 mg doses of caffeine. They concluded that the enhancing effect of caffeine on consolidation of memory was better after the 200 mg dose compared with the dose of 100 mg, but there was no further improvement after the 300 mg of caffeine, compared with 200 mg. From this we can see that if we want to have the benefit of a better long-term memory, due to the caffeine, we’ll need a dose of at least 200 mg of caffeine.

Another thing that the research team has found is that the memory performance was not improved if the subjects were given caffeine one hour before the test with the picture identification.

Numerous studies have shown that caffeine offers many health benefits. For example, it may not only reduce the risk of liver disease, but it may also reduce suicide risk. But, there are also some studies that show that caffeine could disrupt your sleep patterns even after hours after consuming it and that the caffeine from energy drinks may alter the heart function, which is really dangerous.

However, almost all people react different to caffeine, so you need to find out how you react and you must be careful with the dosage.
