Once the magnitude of the impact of caffeine on the brain, just by smelling the aroma of coffee work any brain can increase. Do not believe? This is proof!
Apparently, just by smell the aroma of coffee without drinking the work of the brain can increase. These results are revealed by a study led by Stevens Institute of Technology in New Jersey, United States (US), which tests their theory on business students who take the algebra exam. Through this research, the results obtained that the students who smell the smell of coffee in the exam room to be better. This is because their brains react as if they are consuming caffeine. The researchers mentioned that participants thought their performance would improve if they smelled coffee. Believing in self-efficacy may also be one of the reasons they can finish the exam well.
"Coffee is known to boost energy and intelligence, reduce the risk of type 2 diabetes, protect against dementia and Alzheimer's disease, reduce the risk of heart disease, increase metabolism, and reduce the risk of premature death. With the results of this study, the possibility of one of the benefits of coffee can be obtained without having to drink it!
However, the study did not say whether the chemical effect on the brain when it smells the coffee is the same as that of caffeine when taken.
The effects smell coffee
Although the smell of coffee is said to affect the workings of the brain, but the researchers suggest the scent has a placebo effect. There is a factor believing that the scent may respond positively (or in general can be negative).
When participants recognize the smell of coffee and immediately associate it with caffeine through a cup of coffee, the brain responds immediately as they drink it. "It's not just the aroma of coffee that can make participants perform better performing analytical tasks that make the findings interesting, but participants do feel that their performance will be better, and this also contributes to the increased workings of their brains.
As evidence, the participants were divided into two groups, the group that examined in a coffee-scented room, while the other group in the room were not given any perfume. As a result, the group that tested in the coffee-scented room managed to get a higher score than the other group.
Another benefit of caffeine as a brain stimulant
In addition to improving energy levels, moods, and consciousness, caffeine is a stimulant that stimulates the central nervous system and affects the performance of the brain (psychoactive). This can help you reduce fatigue and focus more. The efficacy of other caffeine, according to a study published in the journal "Nature Neuroscience", caffeine can strengthen the consolidation of memory or memory. Meanwhile, according to research at the University of South Florida and the University of Miami, USA, found that caffeine in coffee associated with reduced risk and slow the process of dementia.
This is certainly good news for coffee lovers who not only love to smell the aroma, but also sip from the cup. If you include people who should be drinking every day, know the dose and levels of caffeine that are safe for the body.

Not only that, a can of soft drinks generally contain 54 mg of caffeine, a can of energy drinks containing at least 80 mg of caffeine, and a pack of chocolate bars containing 9-30 caffeine. "Consuming caffeine as much as 200-300 mg per day or equivalent to 2-4 cups of coffee per day is a safe limit that can be tolerated by physically healthy adults.
