National Sense of Smell Day

National Sense of Smell Day is an American holiday dedicated to the sense of smell. Thanks to this ability, we can better navigate the world around us. The sense of smell also helps us to survive: people will not eat food that smells bad. It is also a tool for aesthetic pleasure: breathing in the fresh frosty air, the fragrance of flowers, perfumes, etc. The holiday is celebrated annually on the last Saturday in April.


The history of National Sense of Smell Day begins in 1994. The S.S.I. initiated the holiday with the goal of increasing people’s awareness of their sense of smell and its mechanisms, as well as diseases that lead to significant impairment. It was created to raise people’s awareness of the sense of smell, how it works, and the diseases that lead to a significant deterioration in the ability to recognize odors or to disappear altogether.

The organ responsible for the sense of smell is the nose. We perceive odors with the help of olfactory cells, which transmit a signal to the brain when we perceive an aroma, and here it gives us an explanation of this aroma: sweet, spicy, etc., and also allows us to distinguish notes from it. That is, we understand that a lemon cake smells like a lemon, an apple smells like an apple, and so on.

Interesting facts

  • A disease in which a person completely loses the ability to smell is called anosmia. In hyperosmia, the sense of smell is preserved, but the person becomes overly sensitive to certain smells.
  • The sense of smell is the most ancient sense organ, which was of great importance for our ancestors. Their sense of smell was several times stronger than ours. It helped them in tracking down prey, determining the location of an enemy tribe, etc.
  • Today there is aromatherapy. Perception of certain smells allows a person to relax, relieve irritation or even help in the treatment of certain diseases.
