Fragrance is like music. Personal preferences and associations greatly influence a person’s response to music’s loudness, style, and the types of harmonies being used – not to mention the lyrics – so that the response is unpredictable and its causes unclear. Much of the aroma­therapy information presented as fact today is based on folklore or inconclusive early research.

Smell 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 while visual memory sinks to 50% after only a few months.  The smells we experience play a crucial role in how we associate with memories and places. Have you ever come across a whiff of something that instantly takes you back to an old memory? Whether it reminds you of your mother’s cooking or a childhood trip to the ocean, a distinctive scent sinks into your brain and stays there.

Smell and Emotion

The perception of smell consists not only of the sensation of the odours themselves but fashion1of the experiences and emotions associated with these sensations. Smells can evoke strong emotional reactions. In surveys on reactions to odours, responses show that many of our olfactory likes and dislikes are based purely on emotional associations.

Smell and Health Care

For example, lavender fragrances have been used in nursing homes to calm residents and emergency rooms to calm worried visitors. Additionally, hospitals, treatment centers and nursing homes are prone to musky smells and malodors making it imperative that the facilities invest in a scenting solution.

Smell and Productivity

Smell is the strongest of the senses and is best able to influence brain activity. Our senses of smell can even affect productivity in office environments. Specific smells 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%.

Once you’ve recognized this ability of fragrance to alter mood and performance, the next step is figuring our which scent to use, and when. Common recommendations for getting energy, subdue anxiety, and help bring on the drowsies are below.
