National Sense of Smell Day – April 26, 2025

National Sense of Smell Day is an annual event held on the last Saturday in April to start the conversation around the sense of smell. Smell is one of the five senses and helps people to recognize any harmful substances in their environment, for example, in their food or in the surrounding air. As people age, there is a natural decline in the sense of smell. The reduced ability to smell makes it vital to raise awareness about detecting such loss in the early stages so as to prevent it from getting worse by taking appropriate remedial action.

History of National Sense of Smell Day

National Sense of Smell Day was founded in 1994 by the Sense of Smell Institute (S.S.I.), the research division of The Fragrance Foundation. Various activities, designed to help children understand the importance of the sense of smell, are organized at museums and educational institutions across the U.S. One of the main reasons behind celebrating this day is to realize the role that the sense of smell plays in our daily lives.

The day also creates public awareness about the various types of disorders related to olfaction, the technical term used for the sense of smell, that has been recently discovered. Anosmia, for example, is a medical condition where people cannot smell. Another rare sensory condition is hyperosmia where people become hypersensitive to certain smells.

In evolution, the sense of smell is believed to be the oldest sense that nearly all living creatures used to have. Before the evolution of the sense of sight or touch, creatures used their sense of smell to detect dangers around them.

Aristotle was one of the first philosophers to write about the capacity to smell. Although no study or theory defines the olfactory system in detail, two American scientists, Dr. Richard Axel and Dr. Linda B. Buck did however conduct thorough research on how people perceive different odors in 1991. Their findings won them the Nobel Prize in 2004.
