The study published by the Journal of Environmental Psychology indicates that the smell of coffee may lead to the stimulation of some functions of the brain, may even make individuals more convinced that they will perform the tests they face better.

The researchers subjected the experiment to 114 students, who asked them to answer a 10-question test, so that the sample–who performed the test in a computer lab–was divided into two groups.

The first group carried out the test in a laboratory with the smell of decaf coffee and other alarms, while the other hall where the second group conducted the test was devoid of any odors. Some 70.4% of the first group members acknowledged that the smell of coffee was significantly noticeable.

The surprise of the study results that the first team grades were significantly better than their peers in the second group, whose members were not exposed to any smells. The smell of coffee also seemed to enhance students ‘ expectations about the quality of performance, based on their answers to the questions asked during the test.

Placebo effect

“Adriana Madzarov “-Professor of Business Administration at the Stevens Institute, and the researcher involved in the study-in remarks to “for our website “: “The coffee-like fragrance has helped students to perform better analytical tasks, which is already interesting; and what’s more, they also thought they were going to audition. Better, we have proven that this expectation was responsible–at least in part–for the improvement of this performance, “Hostess: ” We found that a coffee-like odor, not containing caffeine, had a similar effect to drinking coffee, as the search results indicate an imaginary effect of the smell of coffee may be responsible for The best results achieved by the first group members “.

But is it the smell of coffee that has already stimulated some of the brain functions of the sample, or is it the conviction of the research sample of what is known about the ability of coffee drink to increase the vigilance and attention that led to those good results?

To answer this question, the team designed a questionnaire that was made to the most female group of 208 people who did not participate in the previous research. They were asked about the beliefs of different scents and their perceived effects on human performance.


The participants expressed that they would feel more alert and active in the smell of coffee, compared to the smell of flowers or exposure to any kind of smell, and that exposure to the scent of coffee will increase their ability to perform the mental tasks assigned to them.

The results suggest that expectations about performance can be explained by the prevailing beliefs that the smell of coffee alone makes people more vigilant and vibrant.

Coffee history (coffee roots)

Coffee has stories and anecdotes about where it originated and came out into the “preparation ” and “roasting”, but the historians were unanimous that its genesis was by a shepherd, who observed that his sheep remained vigilant for a long time of night when taking a red plant, and invited him to try it himself; Although historians differ on the nationality of the shepherd and whether he is a Yemeni or Ethiopia, the final predominance was in Ethiopia, with the majority of historians considering that the coffee finder was a sheepherder in the state of “Lehrer ” of the Ethiopian province of “Kafa”, while historians attributed credit to the parents Yemen to exit the coffee plant to the circles “preparation ” and “roasting “.

In his book, “The mayor of the elite coffee solution”, “Abdelkader bin Mohammed al-Ansari “, one of the historians of Yemen in the 16th century, said that “a drink called coffee among the elite by Abu Abdullah Mohammed bin Saeed, known as ” al-Thani “, was found in Yemen, who knew this drink when he went out to Africa (currently Ethiopia); when he came back and drank coffee, he found many properties, including her ability to sleep and laziness, and that she inherited the body lightness and activity. ”

“Al-Ansari ” adds that “the Arabs took coffee from the Yemenis, and the Turks moved them to Europe after they named them with their accent ” Kahka “.

Although scientists differed about the date of arrival of coffee in Europe, it was likely that they arrived in the Netherlands in the early 16th century before the rest of the European countries knew it, and then moved to America in 1717 ., where it was known as the Arab name “Coffee “.

Since that time, coffee has gained popularity worldwide, growing today in more than 70 countries, and green coffee has become the second most traded commodity on the planet after oil.

“Madzarov “: In our study, we found that cafes are the third place a person can go on a daily basis in need to rest and social life, or even to work in a place where coffee is usually smelled.
