Aromas are the pleasant scents that come from various sources, such as food, flowers, and essential oils. They play a significant role in our daily experiences, influencing our mood and memories. For example, the smell of freshly baked bread can evoke feelings of comfort and warmth, while the scent of lavender is often associated with relaxation. The science of aromas is known as olfaction, which is the process of detecting and interpreting smells. Aromas are made up of tiny molecules that travel through the air and are detected by receptors in our noses. This ability to perceive different aromas helps us enjoy our surroundings and can even affect our taste.
