In each of our nostrils, two types of nerves play an essential role in our health. The olfactory and trigeminal nerves capture odors and send information to the brain, more specifically to the olfactory bulb, for interpretation. In turn, this communicates with the cortex, responsible for the conscious perception of odors, but also with the limbic system, which controls mood and unconscious emotions. This is the body's defense against bad smells or irritating or strong odors, creating aversion to those that could harm us in some way.
