Emotions are connected to your sense of smell. Smell travels through the nose and into the part of the brain that controls our memories, ability to learn, and our moods. This part of the brain, the Limbic System, releases endorphins. Endorphins are commonly known as "feel-good" chemicals. Smells have a subtle way of effecting your emotions, which is one the benefits of aromatherapy. Light a candle and begin to feel at ease.
