Does coffee really play a role in purifying your nose from the multitude and overlap of smells? Or is it just "a blessing" trick?
When you visit a perfume shop, a major problem arises for many: after several scents have been sprayed consecutively and the aromas have become mixed together, it becomes difficult to distinguish between them and to identify the components of each fragrance individually. You find yourself lost amidst a multitude of aromatic scents. So, what is the solution?
The usual solution an employee might resort to is to give you some coffee beans so you can recover
"Your sense of smell" - this solution is scientifically unsound.
Dr. Alexis Grosowski of Blowt College demonstrated in a study he conducted on the effectiveness of coffee beans and concluded that the role of coffee beans is only to add a strong scent to your nose so that you become preoccupied with it and distract yourself from the scent of perfumes that have been inhaled.
This is done in a natural physiological way through the sense of smell. When you move away from perfume scents and breathe fresh air or smell any part of your clothes that has not been sprayed with perfume, your sense of smell will return to its natural capacity and your ability to smell will return.
Simply put, if things get mixed up, don't smell the coffee beans, try smelling something that hasn't been sprayed with perfume or breathe fresh air.
