Scents can have immediate and powerful effects on us psychologically. Scientific research has evaluated our responses to odours generally and the implications of smelling particular aromas.
When people smell scents they categorise as pleasant, their mood is likely to improve2. This is important because when we’re in a better mood, we’re more likely to think creatively, be more flexible mentally, and get along better with others9. For example, around the world, floral scents are likely to be interpreted as pleasant smells5. When we’re in a space that smells clean to us, we behave better and in general, people are fairer and more generous3.
The ways that smells can be artificially introduced into a building depend very much on the amount of space being treated, but most applications will require a special machine. This holds a reservoir of scented oil that it vaporises and introduces directly into the air, or through the ventilation system. You can use standard oils or use an expert to create your own custom-made one. Regulating the intensity of a scent in a space is really important, so prior to choosing a signature scent, an onsite test is a must.
To determine if the concentration of a scent in an area is useful but not overwhelming, ask people who do not know that the space is scented about their experiences in the place generally. If they spontaneously mention the scent, reduce its strength. When people do not spontaneously mention the scent but do recognise it is present if asked about it directly, the levels are appropriate.
Ultimately, by actively managing scents in the workplace can create a calming, relaxing and positive atmosphere for employees, increasing their productivity, performance and overall mental wellbeing.
