The smell of warm bread might remind you of a childhood kitchen. A familiar perfume can bring back a person you miss.

Smell has a close link to both memory and mood. It reaches parts of the brain that help us feel and recall. [1]

Signals from the nose use a pathway to reach the brain. Some of these links help us store past events. [2]

Researchers have found that certain smells can bring back early personal experiences. These memories may feel especially vivid or emotional. [3]

Yet the effect is not guaranteed. One smell may remind you of school, while another person remembers a trip.

A smell often becomes tied to an event without our choice. Years later, it can bring that moment back in a flash.

This link offers a chance for reflection. Which scents make you think of people or places you once knew?
