The smell of coffee stimulates the brain and increases cognitive abilities

Working in an environment where the smell of coffee is present would stimulate our brain and increase our cognitive abilities.

Drinking coffee seems to have several benefits. In addition to the physical boost it provides, coffee can reduce the risk of heart disease, diabetes and dementia and even help us live longer. This new study published in Journal of Environmental Psychology reveals that the smell of coffee alone can help brain stimulation.

Researchers at the Stevens Institute of Technology in the United States conducted an algebra test for about 100 undergraduate business students, divided into two groups. The first answered the test in the presence of a coffee-type ambient fragrance, while the control group remained in an odorless room. The researchers found that the smell of coffee allowed higher results to the questionnaires.

“It’s not just that the smell of coffee has helped the volunteers to better meet the analytical tasks, which was already interesting,” said Adriana Madzharov, a professor at the Stevens School of Business. “But the participants also thought they would do better, and we showed that this expectation was at least partly responsible for improving performance.”

In short, smelling a coffee-like scent, which does not contain caffeine, has an effect similar to that of drinking coffee, suggesting a placebo effect of coffee odor.
