Anosmia Awareness Day is observed worldwide on February 27 each year. This awareness campaign was initiated by Daniel Schein, an anosmia sufferer from Woodmere, New York, to highlight the condition known as anosmia, which is the inability to perceive odors. Anosmia can result from various factors and may be temporary or permanent, significantly impacting individuals' quality of life by diminishing their ability to enjoy food and drink. Initially, the event lacked widespread recognition, but it has gained support from Fifth Sense, a UK-based charity focused on assisting those with smell and taste disorders. Fifth Sense has actively worked to promote Anosmia Awareness Day as an internationally recognized event and has launched campaigns like #LongLostSmell to connect smell with memory. Activities associated with the day include talks, symposia, and media campaigns aimed at educating the public about the condition.
