Show 1422: Can You Regain Your Sense of Smell After Illness?

Of all our senses, the sense of smell often gets short shrift. Aside from Marcel Proust’s evocative description of the link between odor and memory, we don’t think much about smell. Scientists have discovered, however, that much of our social interaction relies on olfaction at a subconscious level. It plays a largely unconscious role in our choice of mates as well as in the timing of sexual activity. It is also important for the bonding between mothers and their infants. Consequently, the sense of smell is crucial for the survival of our species, even when we aren’t paying attention.

Losing our sense of smell can be devastating, as too many people learned by experience during the COVID-19 pandemic. Not only did they miss out on pleasant aromas like fresh-brewed coffee or newly mown grass, but they also were at a disadvantage in detecting if there might be gas leaking in the kitchen or a fire smoldering somewhere in the house.

Although some of those who lost their sense of smell during an acute infection subsequently regained it, others did not. Too many people are still suffering from anosmia. Is there anything that can be done to help them?

This week, our guests take two different approaches to the sense of smell. We talk with a surgeon who treats people having difficulties with that sense. In addition, a nurse describes utilizing the sense of smell for aromatherapy in integrative healing. Learn about the fascinating science of smell.
