When you think of the five senses, your mind might leap first to your sense of sight and all the visual wonders you might behold. However, you may be surprised how important the sense of smell plays in your day-to-day decisions, emotions, and memories.
Aroma and Memory
Scent is the sense closest linked to memory. Studies have shown that people can remember a scent with 65% accuracy after 1 year compared to loss of visual memory by 50% after only a few months. Fragrances we experience play a crucial role in how we associate with memories and places.
Aroma and Productivity
Our senses of smell can affect productivity in office environments. Specific fragrances have been found to increase alertness which in turn results in higher productivity rates. One study found that when lemon oil was diffused throughout a Japanese office building, productivity among data entry operators increased by 54%. Scents can also be used to ward off mid-afternoon brain fog by revving your concentration levels.
