The scents of rosemary, lemon, lavender, and orange can help improve memory in Alzheimer’s patients. The smell of citrus can motivate people to clean their homes by using room scent diffuser. And sniffing spiced apples can lower blood pressure. If these micro-examples of the benefits of smell sound like an ad campaign for scented candles and scented oil diffuser sticks, think again: they could be case studies for how designers might improve the quality of life in cities.

As Lance Hosey points out in this past Sunday’s opinion section of the New York Times:

Whole cities can be defined by their scent. Streets-capes fill with the aroma of roasting coffee spilling from Seattle’s cafes, or the bouquet of fruit and flowers at Amsterdam’s markets, or the sugar and cinnamon wafting out of Viennese pastry shops. 

These olfactory identities don’t exist entirely by accident. Scent marketing–like when a popcorn shop lures customers in by pumping the buttery, salty smell onto the sidewalk–plays to our most basic instincts in an effort to procure a sale. But if businesses can use scents through aroma lite diffuser to target customers, or even just develop brand loyalty, why can’t urban planners and designers do the same to improve our experience of urban environments?

How can we use the power of scent to design better cities?

Maybe it needs a deep think that how to create a better and special life, but no doubts that natural scent diffuser as a carrier of scent to improve people the scenting experience and life. That aromatherapy oil diffuser electric scent machine can scent automatically anytime and anywhere.

So aromatherapy air diffuser will be a powerful tool of scenting to design better cities.
