So-called "scent profiles" have been documented to improve productivity, avoid a phenomenon known as olfactory fatigue, and achieve a psychological familiarity helpful to marketers when developing brand recognition. This is one of many approaches companies are attempting to use in order to lure workers back into the city's emptying central business districts. 

Marriott, the nation’s second-largest hotel chain, has for two decades incorporated scents into all 30 of its Bonvoy properties, and (despite the HR headaches caused by allergy risks) there is now a growing interest among heavyweight commercial clients like SHVO and CBRE looking to improve indoor air quality in the wake of the pandemic.

Allison Lobay, global account manager of Air Aroma, shared with the Commercial Observer: "Some scents are associated with improved productivity. In the office, citrus fragrances are used to energize people or help them feel happy," adding, "If bosses want to soothe employees who are anxious about coming back to the office, lavender might be more appropriate, she said, for a more 'calming, relaxing, comforting' effect."
