The Science of Smell: Understanding How We Smell

Our sense of smell, which is capable of detecting around a trillion scents, is more powerful than our other senses. Smells are chemicals in the air, and our noses have receptors that detect these chemicals, sending the information to our brains. Our sense of smell is deeply connected to our emotions and memories, as the same brain regions are responsible for processing both. Smell training, which involves smelling distinctive scents regularly, can help reawaken and activate our sense of smell, even after it has been lost.
