Our olfactory nerve is responsible for controlling our sense of smell and is directly connected to the part of the brain that monitors memories and emotions.
Mood, concentration, memory recall and emotion are, thus, affected or triggered by scent. In fact, 75% of emotions generated daily are due to smell. This makes us x100 more likely to remember something we perceive through smell rather than through sight, hearing or feeling.
Research shows that there is a 40% improvement in mood after being exposed to a pleasant scent.
