After breakfast or lunch, "coffee" is often drunk for alarm clock and refreshment. But in the near future we may have a day to drink coffee to “improve our memory”.


A study conducted in the United States revealed that "caffeine" may improve memory. The British media BBC News reports .

According to the media, the research was conducted by a research team at Johns Hopkins University in the United States. We conducted an experiment to investigate the relationship between caffeine and memory, using people who do not take caffeine on a daily basis as subjects.

First, each subject is shown a series of pictures.


After 5 minutes, give all subjects either a tablet with caffeine (the same amount of caffeine in a large cup of coffee) or a dummy tablet.

The next day, the subjects were retested to see how much they remembered the picture shown the day before.

The picture that was prepared is similar to the one on the previous day, but slightly different . He showed them to the subjects and investigated whether they would mistakenly answer "same" or give an accurate answer "slightly different but similar". Then, it seems that more people were able to guess the picture more accurately in the group of subjects who took caffeine than in the group of subjects who did not take caffeine.


However, it is still early to be impatient after receiving this research report, saying, "I have to drink coffee every day from today!" Caffeine has also been shown to have negative side effects for some drinkers. Also, if you drink too much, it may have an adverse effect on your body.

In addition, this experiment was conducted on subjects who do not normally take caffeine. Different people may also have different amounts of caffeine that affect memory, said Michael Yassa, a professor at the university who led the study.

For now, it seems better to keep an eye on the relationship between caffeine and memory in terms of “potential”. I would like to continue to look forward to future research.
