You are what you eat, so the old buzz phrase goes. But new research looking at people’s moods and smarts may have us one day saying you feel as well as what you smell.

Researchers in Great Britain have concluded that sniffing rosemary aromatherapy oil makes a person feel more content and gives a slight boost to performance.

The researchers exposed 20 study participants in their 20s to the scent of rosemary aromatherapy oil anywhere from four to 10 minutes.

Those who smelled the rosemary oil for less time were less likely to report feeling “content.”
