The environment where one works or studies is not neutral. Temperature, light, noise, and the aroma of the space directly influence attention span, information retention, and cognitive performance. Research on olfaction and the brain has been yielding solid results for decades. And the conclusions are clear: certain aromas activate key cognitive functions.
Part 1: The connection between smell and mental performance
The olfactory nerve connects directly to the hippocampus—the memory center—and to the prefrontal cortex, responsible for sustained attention and decision-making. No other sense has this direct access.
When the correct aroma is present in the environment, the brain receives an activation signal that improves alertness without causing stress. It is the olfactory equivalent of turning on the light in a dark room: the brain "gets going" naturally and without conscious effort.
Part 2: Rosemary, mint, and citrus — the three great activators
There are three aromatic families with consistent evidence in cognitive performance studies:
- Rosemary: The most studied in academic contexts. Its active components—1,8-cineol and camphor—are associated with improvements in working memory and processing speed. Studies in school environments documented better test results in memory tests for students exposed to rosemary compared to control groups in unaromatized spaces.
- Mint: Activates the central nervous system and improves sustained attention. Especially effective in monotonous or repetitive tasks. In office environments with administrative work, it reduces cognitive fatigue during long shifts.
- Citrus (lemon, bergamot): Generate a positive state of alertness without the tension produced by stimulants. They are the most versatile aromas for spaces with high turnover, where a quick and constant effect is needed.
Part 3: Practical applications by type of space
Academies and training centers. The sensory environment influences how students associate the space with learning. A classroom that smells good and uses activating aromas establishes positive conditioning: the brain learns to enter concentration mode when it recognizes that environment. Aromatization with rosemary or mint during class hours is a direct investment in the center's results.
Offices and workspaces. Long working hours erode concentration. Citrus and menthol aromas counteract this effect without interrupting work. Several consulting and technology companies in Europe have incorporated aromatization as part of their well-being policy, with documented improvements in productivity and employee satisfaction.
Coworking spaces. A shared workspace needs its own identity to justify choosing it over working from home. Aroma is one of the elements that contributes most to creating that identity: it makes the space memorable, pleasant, and mentally associated with productivity.
Meeting rooms and presentations. A client or candidate's first impression is formed in the first few seconds. A space that smells good conveys order, care, and professionalism immediately and without words.
Part 4: How to implement it correctly
The key is intensity and consistency. An overly intense aroma creates distraction—the opposite of the desired effect. Professional cold nebulization allows for precise control of aroma concentration in the space and programming of diffusion schedules, ensuring a constant and subtle level throughout the day.
BENDIS offers specific fragrances for work environments—green tea, fresh mint, lemon, bergamot—with professional nebulizers that cover up to 150m² and can be programmed by schedule. From €39.99/month with the device included.
Because the environment where one works is not a secondary detail. It is part of the result. bendis.es
