The sense of smell is a powerful thing. Smells can trigger memories, engage endorphins, and can have a tremendous impact on the human body and mind’s sense of well being. Certain scents can affect the way we perceive our environment and create a variety of moods. Whether we perceive a scent as pleasant or unpleasant, our sense of smell is directly linked to our brain. Though as humans we utilize less of our brain capacity than animals, when it comes to smell, there is still a psychological connection between smell and emotion.
