The Science Behind the Familiar Scent of Home.

The distinct aroma of our homes is a combination of many scents, including air fresheners, candles, laundry detergent, cleaning products, and food. Our personal smells are tied to our unique DNA sequence, and the scents of our homes hint at where we live. The tie between human emotions and sense of smell is stronger than with other senses, and the smell of our homes becomes entangled with our recognition of comfort and security.
